My 2017 Toyota has a feature I’ve recently discovered that doesn’t just automatically turn my headlights on at night, but it will turn high beams on if I’m the only one on the road and will automatically turn them off when a car approaches – or even if I suddenly get behind another car. After observing for a bit, I’ve realized it’s scary accurate. How does this work?
Note: it doesn’t even turn them on if it’s just street lights, it seems to differentiate between street lights and headlights on cars.
In: Engineering
Auto high beam requires that one uses either radar or image data to detect on coming traffic and its distance to EGO (your vehicle) car. Upon detection of object and measurement of distance the headlamps can be placed in right state.
BTW with new headlamps with LEDs you can actually steer the headlamp beam based on recognition of environment e.g shine them on street sign in a dark alley
