This time of year, with the short short days and endless nights, a young lady's thoughts naturally turn to driving safely after dark.
Last October, we did a post called Bright Lights, Dark Road: All about Headlights about the history of the headlight. But this post is all about the future! Specifically adaptive headlights and their effect on road safety.
What are adaptive headlights and how to they work?
Adaptive headlights, as the name suggests, adapt to your car's movements. The lenses of the headlights are able to swivel from side to side and up and down.
Adaptive headlight systems are controlled by an electronic control unit (ECU) and generally include:
- A sensor for steering input to monitor the angle of the steering wheel
- Wheel speed sensors that monitor the rotation speed of each of your tires
- A yaw sensor to monitor your car's side-to-side movement (i.e. turning a corner, going around a bend)
- A level sensor to monitor whether your car is tilted forward or backwards (i.e. going up or down a hill)
- Tiny motors that operate each headlight
The ECU monitors and analyses all of the input from these components to determine where and how to move the headlights to best illuminate the road. Check out this mesmerizing video of adaptive headlights swivelling about.
