MI-TECH concept shows how future Mitsubishi SUVs could be like

Mitsubishi Motors Corporation (MMC) has a long history of developing SUVs. In fact, together with Isuzu, it could be said that the company was the pioneer in the modern SUV which in the early 1980s was referred to as a ‘dual-purpose vehicle’. The vehicle was the Pajero and along with the Isuzu Trooper which appeared almost at the same time, consumer perception of such vehicles changed from being mere workhorses to alternatives to passenger cars.

With almost 4 decades of experience in producing SUVs, it would only be expected that MMC is now developing such vehicles which will run with electric motors, in line with industry trends for the coming decade. At the Tokyo Motor Show this year, it displayed the MI-TECH concept to give an idea of what a small-sized electrified SUV could be like.

Compact buggy-type vehicle
The design is that of a dynamic buggy-type vehicle with the familiar signature Dynamic Shield that is used for the front of the latest Triton. The new front design concept (which may be how the ‘face’ evolves) uses a satin-plated colour in the centre of the grille, with copper as a secondary colour to accentuate its expressiveness as an electrified vehicle.

T-shaped headlights are embedded in the front end to emphasize a distinguishing outward appearance. On the lower bumper, an aluminium skidplate is placed on both sides to protect the body while the centre section has an air intake.

On the sides, the highly raised over-fenders and large diameter tyres project a high level of mobility, SUV power, as well as the stability to thoroughly grip the terrain. The body radiates grandeur and sharpness with a design reminiscent of a machined metal ingot, while the use of side-steps on the carved sides balances utility with design.

The rear end design is dominated by a large and bold hexagon shape, again exuding the impression of being machined from solid metal ingot to emphasize robustness and strength. The T-shaped tail lamp shared the same design pattern used on the front end, as do the rear bumpers.

Functional cockpit with infographics
Inside, a horizontal instrument panel and clean, functional design make operating the MI-TECH easier. Keyboard-shaped switches are positioned on a centre console, and the front handgrip also functions as a hand pad to make the switches easy to operate. Functions are presented in a straightforward manner, easy to understand just by seeing them and with a reassuring feel when pressed.

The horizontal theme is further accentuated by copper lines added on the instrument panel and steering wheel. For extra peace of mind, the front windscreen presents all the relevant information in graphics such as vehicle behaviour, terrain recognition and optimal route guidance.

PHEV powertrain of the future
The power generator in the new PHEV drivetrain is a lightweight, compact gas turbine engine-generator in place of the traditional petrol engine. The gas turbine engine-generator has a powerful output for its size and weight with the added benefit of flexibility to run on a variety of fuels such as diesel, kerosene and alcohol which can be selected depending on the regions.

Building on its PHEV powertrain experience, MMC has evolved its Super All Wheel Control (S-AWC) integrated vehicle dynamics control system to operate with a Quad Motor 4WD System with front and rear Dual-Motor Active Yaw Control (AYC) units. Making the brake calipers electric has also allows for high response, high accuracy control of drive and braking force of the 4 wheels while delivering a drastic improvement in turning and traction performance.

When driving off-road and 2 of the wheels lose traction, the ability to transmit the optimal driving force to all 4 wheels makes it possible to transmit force to the 2 wheels still on the ground and keep driving. It is possible to execute 180-degree spins by counter-rotating the left and right wheels.

The MI-TECH also comes equipped with a Human Machine Interface (HMI) which displays varying information detected through sensing technology including advanced optical sensors on an augmented reality (AR) windscreen. With vehicle, road, and surrounding traffic conditions shown on the AR glass, the driver can make accurate decisions even in poor visibility without taking his eyes away from the view ahead.

Explosions that prevent electric shocks in electric vehicles after accidents

Explosions are normally associated with something negative or bad as they generate a lot of energy which can be damaging. However, there are also some explosions which can save lives – these are tiny explosions which reduce the risk of electric shocks after a vehicle has an accident.

With more and more electric cars on the road, many drivers are increasingly uncertain what they should do or not do in the event of a collision. Electric motors also present rescue crews with new challenges. In fact, like any other vehicle, electric vehicles are equipped with safety features for such events.

Deactivating electrical circuits right away
For example, Bosch semiconductors help prevent the risk of electric shock after an accident. Specially designed microchips deactivate the vehicle’s power circuits in a fraction of a second. This enables rescue crews to set to work immediately and ensures that first responders and the vehicle’s occupants remain safe.

“Our semiconductor technology plays a vital role in the safety of hybrid and electric vehicles,” said Jens Fabrowsky, Member of the executive management of Bosch’s Automotive Electronics division. Bosch supplies vehicle manufacturers with semiconductor chips for incorporation in special systems that safely disconnect the battery in the event of a collision.

“Faced with the growing number of electric vehicles that could potentially be involved in collisions, such systems are absolutely essential if we are to fulfil our mission of helping and rescuing victims of road accidents as rapidly and safely as possible,” added Karl-Heinz Knorr, Vice-President of the German firefighters association.

Higher voltage than home electrical outlets
For a lot of people, damaged cables as the result of an accident are a cause for concern: the current from the battery pack could leak into the metal bodywork of a hybrid or all-electric car. After all, these batteries are designed to deliver a voltage of 400 to 800 volts (the voltage from your home electrical outlet is 240 volts and that’s already dangerous). But they can rest assured because Bosch semiconductor chips ensure that the high-voltage battery is automatically disconnected, so that nobody at the scene of the accident – vehicle occupants, rescue crews, first responders – comes into contact with current-carrying components.

Mercedes-Benz A-Class PHEV — *New models like the Mercedes-Benz A-Class Plug-In Hybrid variant have a lot of high-voltage cables and systems which must be shut down to avoid causing harm to rescuers.*

The semiconductor devices are part of a pyrotechnical safety switch system, or pyrofuse. These systems ‘blow out’ whole sections of the cable connection to the high-voltage battery by means of miniature explosive charges, thus quickly and effectively shutting off the power circulation. Bosch semiconductors play a decisive role in these systems. If, for example, the airbag sensor detects an impact, the tiny devices – measuring no more than ten by ten millimetres and weighing just a few grams – trigger the pyrofuse. This sets off little explosions that drive a wedge into the high-voltage cable between the battery unit and the power electronics, disconnecting the two. By cutting off the flow of current this way, the risk of electric shock or fire is eliminated.

Reliability in millions of applications
The CG912 integrated airbag system IC used in the pyrofuse system is an application-specific integrated circuit or ASIC. The specific application in this case is automotive safety. “Our ASICs, which are no bigger than a fingernail and yet populated with millions of transistors, are custom-designed to activate safety functions reliably within a fraction of a second,” Fabrowsky said.

Originally developed by Bosch to trigger the release of airbags, the CG912 has performed reliably millions of times in this application. Modern vehicles contain dozens of ICs to control not only safety features such as airbags and belt tensioners but also cruise control, distance sensors, high-beam assist, lane-keeping support, rain sensors, and driver drowsiness detection. “Nowadays, there is hardly any area of automotive engineering that does not involve the use of microchips,” he noted.

Global debut for two Mitsubishi Motors concept models at Tokyo Motorshow

Visitors to the Mitsubishi Motors (MMC) booth at the coming Tokyo Motorshow later this month will be shown two new concept cars that preview the carmaker’s future technologies: the MI-TECH Concept and the Super Height K-Wagon Concept.

MI-TECH Concept
The MI-TECH Concept is said to embody the values of MMC’s ‘Drive your Ambition’ brand message under the concept of “An electric SUV that delivers unparalleled driving pleasure and confidence over all terrain in light and wind”.

The concept car features a new, downsized and lighter plug-in hybrid Electric Vehicle (PHEV) drivetrain, a 4-motor electric 4WD system and advanced driver assistance with active safety systems. The MI-TECH name is derived using the ‘M’ from Mitsubishi and the ‘I’ from ‘Intelligent, Ingenious and Inspired’, while the TECH is an abbreviation of Technology.

The MI-TECH’s advanced PHEV system is optimised with a light and compact unit for this small size SUV, using a gas turbine engine generator instead of a petrol engine generator. This allows the driver to use pure-electric driving mode and series hybrid modes, delivering the smooth and powerful performance characteristics inherent to electrified vehicles.

Its 4-motor 4WD system called Quad Motor with Dual Motor Active Yaw Control (AYC) has two motors for both the front and rear axles. This allows optimum torque to be delivered to all the wheels, bringing confidence to the driver with precise handling for the daily use and also enhanced performance for adventuring off-road.

Inside, a human-machine interface (HMI) projects a variety of information, detected by using advanced optical sensing technology, onto the windscreen of the vehicle. While the MI-PILOT driver assistance system not only alerts the driver in potential collision situations, it also supports the operation of the steering wheel and brakes.

In addition, active safety systems support the driver in avoiding collisions and mitigating any collision damage. All these systems work together to deliver a reassuring, safe and enjoyable driving experience.

Super Height K-Wagon Concept
The new-generation Super Height K-Wagon Concept answers the wishes of those drivers looking to expand their list of destinations and going further towards to the horizon. This concept features the roomy interior space as is standard of the genre while delivering the performance and functionality expected in this category, with a SUV touch.

Few details are available but MMC says it delivers nimble handling and brisk performance while maximizing interior space. It also offers reassurance and safety to all occupants with MI-PILOT driver assistance technology, Forward Collision Mitigation, mis-acceleration mitigation and other advanced active safety systems which earn it SAPO CAR (Safety Support Car) S Wide classification from the Japanese government.

*The Engelberg Tourer concept SUV, unveiled earlier, will also be on display.*

New Land Rover Defender’s Mild Hybrid Electric Vehicle system provides ‘future-proofing’

Throughout its 67-year life, the original Land Rover Defender was offered only with petrol or diesel engines. That’s not unusual since it was developed from a product of the late 1940s, long before the era of zero emissions and greater consciousness to preserve the environment. Its powertrains were robust, as required by customers, and had been improved to deliver better performance and meet progressively stricter emission control regulations.

However, when it came to developing the successor, the world had become a very different place. From the 1970s onwards, air pollution – blamed largely on exhaust emissions from motor vehicles – persuaded governments to introduce regulations forcing carmakers to reduce emissions. These regulations, especially in the more developed countries, kept getting tougher and tougher. And with rising fuel prices, there was also a need to reduce fuel consumption even if there was indifference to concerns about fossil fuel supplies diminishing and running out at some point in the future.

Electrification the way to go
For Land Rover, as for other carmakers, it was clear that there were limitations to engineering the internal combustion engine to meet toughest regulations. The better solution was to use electrification, an approach that had become increasingly viable since Toyota and Honda introduced hybrid powertrains in the late 1990s. Pure electric powertrains remain expensive due to the high technology costs but hybrids are now into the mainstream and almost every carmaker has adopted the technology.

So for the new Defender, it was clear that while less developed markets would still require conventional engines, the future dictated that there must be a hybrid powertrain under the bonnet. This led to the development of Mild Hybrid Electric Vehicle (MHEV) technology that is available from launch while a Plug-in Hybrid Electric Vehicle (PHEV) powertrain will join the range next year. This will offer silent zero-emissions driving in EV-mode, giving Land Rover owners an entirely new experience off-road.

MHEV with 48V system
A key feature of the Defender’s MHEV is its 48-volt battery pack consisting of 14 x 8Ah lithium-ion pouch cells that can store up to 200Wh of electricity. The MHEV system is not new to Land Rover, having first been used in the Evoque and has been further refined. Separate from the normal vehicle battery, it generates up to 142.5 Nm of torque which enhances acceleration.

A DC/DC converter installed at the back provides energy to the battery pack as well as the vehicle’s conventional battery. There’s also a Belt-Integrated Starter Generator which ‘harvests’ electrical energy while driving. Whenever the driver lifts off on the throttle pedal, electricity is regenerated to the battery pack where it can be utilized.

2019 Land Rover Defender — *The new Defender’s platform has been engineered for conventional petrol and diesel powertrains as well as hybrid powertrains.*

The in-line 6-cylinder 3-litre Ingenium petrol engine features both a conventional twin-scroll turbocharger and an advanced 7 kW electric supercharger. In combination with the other advanced technologies, total output is 400 ps/550 Nm with a claimed 0 – 100 km/h time of 6.1 seconds. Fuel consumption is claimed to be 10.4 kms/litre.

Software updating – without going to the service centre
The extensive array of electronic systems in the new Defender mean that ‘future-proofing’ is necessary and software updates can be sent over the air periodically. Up to 14 onboard electronic control modules, more than any previous Jaguar Land Rover vehicle, can receive updates, without the need to visit a Land Rover service centre. In this way, the Defender will get better with age. Customers in remote locations can still get the updates – all that’s required is a data connection via a satellite-phone.

Although electronic systems installed in motor vehicles these days are ‘hardened’ and able to withstand the harsh conditions during daily use, they have to endure even more severe and extreme conditions in a vehicle like the Defender. Given that many owners will go off-road and over the roughest terrain on the planet, Land Rover engineers had to conduct rigorous testing all over the world and in the most extreme conditions. Serious attention was given to electrical connections and the effects of impacts on components like the battery pack. Even in the 21^st century, the original 4×4 reborn has to maintain as well set new standards for toughness and capability.

Production of High-Voltage Batteries for BMW Hybrid Vehicles underway in Thailand

In the early years of the auto industry, the factories that produced cars and the parts for them were once confined only to the countries that the manufacturer was established in (BMW in Germany, Toyota in Japan, Ford in the USA, etc). However, as the auto industry rapidly expanded around the globe and cars were being sold in other countries as well, it made sense to produce them closer to the markets. And from the 1960s onwards, as more countries began industrialising – like Malaysia – incentives were also offered to carmakers to invest in local production.

Globalisation of the industry has led to factories being set up all over the world, some to serve a few markets and some as production hubs for regions or even the entire world. The need to have huge volumes for economies of scale that drive down costs is one reason for this approach. There are also political considerations which come into play as exports of vehicles from one country to another need to be ‘balanced’.

While the construction of new factories to make vehicles is ongoing, there is now a wave to establish factories to supply parts and systems for the coming era of electrification. The next decade will see a leap in hybrid and electric vehicles and demand will be great, so the factories must start up now in order to be able to meet that demand.

Incentives matter as well as policy clarity and stability
Choosing a country to build a new factory requires not just careful planning but also consideration of the incentives offered by the government. The investments and job opportunities as well as export potential are also attractive enough to governments to offer investments to attract carmakers. Clarity and stability of automotive policies is also important as carmakers plan over many years and they need to be assured that changes are not made just because a new minister has taken over and had other ideas about the direction.

Thailand has been good at policy stability, which is probably on reason why a number of global players built their production hubs there. Changes of government may occur but policies are maintained and that’s what matters.

BMW chooses Thailand
Following on from BMW Group Thailand’s earlier endorsement for incentives by Thailand’s Board of Investment (BoI) for a 700 million baht (about RM96 million) outlay in BMW plug-in hybrid electric vehicle (PHEV) production, the company has jointly invested with DRAXLMAIER Group in this battery assembly plant, worth 500 million baht (about RM69 million).

“This new beacon for e-mobility innovations will further unlock the competence of Thailand’s automotive industry. The incentives from BoI also symbolize the unity between the public and private sectors in this undertaking towards a sustainable future,” BMW notes.

BMW Group Thailand has thus marked another historic milestone with the inauguration of a local high-voltage battery production plant in partnership with the DRAXLMAIER Group, one of the world’s leading automotive suppliers and a partner of BMW Group since 1966. BMW Group Thailand launched the local assembly lines in July 2019 at the plant in WHA Chonburi Industrial Estate 2. The high-voltage battery assembly plant is assembling both battery modules and the battery itself.

Uwe Quaas, MD of BMW Group Manufacturing Thailand said: “One of the pillars of BMW Group’s global strategy is electrification, and BMW Group Manufacturing Thailand is underlining its commitment to this mission by taking another big step forward in our electro-mobility strategy. The start of local battery production enables us to better respond to growing domestic demand for electrified vehicles in Thailand. This new capability also strengthens the performance of Plant Rayong in fulfilling the country’s mission of sustainable mobility.”

Fully trained workforce
The high-voltage battery is a central element of partially and fully electrified vehicles and a highly sophisticated component that requires specialized skills to produce. Thanks to the advanced training and qualification programs initiated in September 2018, the staff from the DRAXLMAIER Group who have participated in the battery production training program at BMW’s Group Plant Dingolfing – the BMW Group Competence Centre for e-drive production – and the BMW Group pilot plant for e-drivetrains in Munich, are now ready for the high-tech assembly work to produce the latest generation (Gen4) of the BMW Group high-voltage batteries

This involves the use of cutting-edge production technologies onsite including laser welding, plasma activation, robotics, gluing, automated optical and electrical inline quality inspection along with end-of-line testing. The training is also focused on supporting a highly automated process, which is an important part of battery module production, as well as comprehensive quality assurance, product methodology and technology, rework, and analysis.

World-class standards and quality
Equipped with a strong grasp of battery production skills, the staff will work on battery cells provided by a supplier in the Asian region along with other imported parts – such as aluminium housing, electronics, and cables – to roll out high-voltage battery packs that meet BMW Group’s world-class standard and are in full compliance with Thailand’s local content requirement regulation.

Completed battery packs will then be transported to Plant Rayong for the production of the entire range of BMW 5-Series Plug-in Hybrid Vehicles, which has been in operation since July 2019. Since 2017, BMW Group Manufacturing Thailand has assembled four BMW plug-in hybrids at Amata City Industrial Estate, Rayong province.
