Modern vehicles come with cutting-edge security features that are intended to prevent theft. But according to a recent report, even the most advanced anti-theft safeguards can be evaded by connecting to a headlight wire. A method called CAN injection.
The headlight module of your car is where this keyless auto theft method starts, however, thieves only choose this point of entry since it gives them the simplest access to a car’s CAN bus system. If you’re wondering what a CAN bus system is, it’s the internal computer network that keeps everything running. It’s basically numerous ECUs throughout a modern vehicle that communicate with each other.
Ford has always urged drivers to keep ‘eyes forward and hands on the wheel’. It’s obvious that maintaining attention on the road ahead is important to immediately spot any danger. At the same time, both hands should be on the steering wheel to always be able to take avoiding action in an emergency. That’s why using a mobilephone when driving is dangerous and in many countries, an offence.
Over the years, various technologies have been introduced to help drivers stay focussed ahead. Head-up Displays (HUDs) are one of them, the technology having been taken from fighter aircraft. By projecting important information on the windscreen, the driver can be informed while still looking ahead.
Now Ford researchers have developed a new headlight technology that could help ensure those behind the wheel literally keep their eyes on the road. The new technology can project directions, speed limits or weather information onto the road so the driver keeps looking ahead.
The technology is intended for use at night, of course, as that is when driving can be riskier. Statistics in the UK show that 40% of collisions happen during the hours of darkness, even though there are far fewer people driving than in the daytime.
This risk is increased whenever a driver takes their eyes off the road. A vehicle travelling at 90 km/h covers 25 metres per second, meaning even a short glance at the navigation screen on the dashboard can result in ‘driving blind’ for 10 metres or more. On an unlit road, this could potentially mean missing an important sign or a bend in the road.
Ford’s researchers have therefore come up with a system that projects important information onto the road using high-resolution headlights. The technology could even provide the driver with information about changes in weather, such as rain falling, fog, slippery conditions, or a slippery road ahead.
Connecting the headlight to the navigation system could display upcoming turns, while the width of the vehicle could be projected onto the road, helping the driver to judge whether the vehicle will fit through a gap or into a parking space.
The technology could benefit other road users too. For example, a pedestrian crossing could be projected onto the road, both for the view of the driver and the pedestrian, in situations where the existing road markings are faded or unclear. Other possibilities include showing a path for the driver to follow to ensure cyclists are passed at a safe distance.
“What started as playing around with a projector light and a blank wall could take lighting technologies to a whole new level. There’s the potential now to do so much more than simply illuminate the road ahead, to help reduce the stress involved in driving at night. The driver could get essential information without ever needing to take their eyes off the road,” said Lars Junker, Features and Software, Advanced Driver Assistance Systems, Ford of Europe.
The built-in headlights in every car today have been around for about 100 years and over the decades, the lighting systems have evolved to make the illumination stronger, giving a better view of the road or ground ahead. From making headlights more powerful, the engineers have also been making them operate ‘intelligently so that optimum illumination is achieved with changing conditions.
Driving in the dark can be stressful, especially on unfamiliar, winding roads. Ford is therefore working on a new technology to increase comfort and safety when driving after sunset. The company has already done pioneering work in the camera-based recognition of traffic signs and lane markings to optimize headlights in order to better illuminate streets in the dark, especially at intersections.
Now, engineers from Ford Research and Advanced Engineering Europe are testing technology that uses real-time location data to effectively show the car the way to go. The predictive ‘smart’ headlight system directs beams into upcoming corners – even before drivers may have seen them, illuminating hazards and other road-users more quickly and effectively.
How it works
The prototype advanced lighting system uses GPS location data, advanced technologies and highly accurate street geometry information to accurately identify turns in the road ahead. An algorithm calculates the trajectory and speed of the vehicle to proactively adjust the direction of its headlights, providing optimal light coverage of bends, junctions – and even hazards lurking around the corner.
If the vehicle encounters a stretch of road where location data is not available, the system will work alongside camera and steering‑based dynamic headlight-bending technologies to continue to intelligently light the road until the location data improves.
Researchers have made extensive use of ‘digital twin’ simulation that recreates the physical world in a virtual environment. The simulator accurately calculates how light falls and reflects in the real world, enabling researchers to better visualise and optimise the technology for drivers. The Ford researchers used a simulation that reproduces the real world in a virtual environment. The simulation environment calculates the correct reflection of the headlights as in the real world, so that the researchers can visualize the lighting technology realistically and optimize it in terms of traffic safety.
“The predictive lighting technology we are now developing could one day make driving in the dark so easy that the driver basically just has to follow his headlights,” said Michael Koherr, Lighting Research Engineer, Ford of Europe. “This new map and location-based system is the next step in our search for how we can make driving at night as easy as it is during the day.”
Road Edge Detection – available today
The advanced lighting technology will complement another new technology that Ford has developed which can be especially useful on rural roads at night – Road Edge Detection. Roads in rural areas can be tricky as they may not only lack proper lane markings but also give way to open land, muddy ditches and sheer drops.
Ford’s new technology can help make rural driving easier as Road Edge Detection scans the road ahead and can gently steer the vehicle back on track when needed. Designed for use at speeds of 70 – 110 km/h, Road Edge Detection relies on a camera located below the rearview mirror to monitor road edges 50 metres in front of the vehicle and 7 metres to the side.
How it works
Where a paved road becomes a soft side, gravel hard shoulder or grass, the system provides gentle steering support as required to prevent the vehicle from drifting off the carriageway. The system features an advanced algorithm that determines when there are clear structural changes from the road to the area beside the road. It can also provide steering support on marked roads when the lane marking is obscured or hidden by snow, leaves or rain.
If the driver is still close to the edge following initial steering support, the system vibrates the steering wheel, to prompt the driver to steer. At night, the system uses the illumination from the headlights and functions as effectively as during the day.
While predictive lighting technology is still under development, Road Edge Detection is already available in Europe on certain models and will be offered in more models in future the way advanced safety systems like Pre-Collision Assist and Automatic Emergency Braking have been progressively included in almost all models.

Lexus has marked another significant advance in automotive lighting technology with the introduction of a BladeScan-type adaptive headlight system, a world-first. To be offered on coming models starting with the new RX, BladeScan gives both an extended field of forward illumination and more accurate lighting control to support safer driving at night and in poor weather.
The current RX already benefits from automatic or adaptive high-beam LED lighting as part of the Lexus Safety System+ package of active safety features, to maximise headlight illumination without the risk of dazzling other road users.
BladeScan goes further by providing more precise photometric control of the area of illumination in front of the car, with accuracy to within 0.7 degrees compared to around 1.7 degrees for the current technology. This means it can light up areas that would be difficult to see with a conventional high-beam system, such as the road margins, and give earlier illumination of road signs and pedestrians.
Longer range for pedestrian recognition
With BladeScan, pedestrian recognition at night has been improved to 56 metres in front of the RX, compared to 32 metres with the current system. This obviously makes night driving much safer as the driver will also be able to spot pedestrians from a greater distance and drive carefully.
While other manufacturers have increased the number of LEDs in their headlight systems to improve lighting resolution, Lexus’s system uses a more cost-effective array of LEDs. These are contained in a compact module located in the front corner of each headlamp, alongside the familiar triple-eye light arrangement.
Rather than shining light forwards, the LEDs in each BladeScan module cast light diagonally across two blade-shaped mirrors that rotate at high speed. The precise synchronisation of the mirror rotation and the switching on and off of the LEDs creates the shading effect; the light is then reflected into a lens which casts the beam on to the road ahead, without the risk of dazzling oncoming traffic or drivers of vehicles ahead.
The new system is another example of the brand’s reputation for technical innovation. It was the to introduce LED headlights on its LS flagship model in 2007, and the first to produce adaptive high-beam headlights, again initially for the LS, in 2012.
