Driver assist systems in cars are instruments that can save lives. They include for example adaptive cruise control (ACC), brake assist systems, or lane departure warning systems (LDW). The latter warn the driver when he is about to leave the lane unintentionally. This is accomplished with various systems and computers that determine the vehicle’s position in the lane. When the car is in danger of leaving the road, the system activates an electric motor in the steering wheel that causes the wheel to vibrate, warning the driver. maxon motor is supplying a luxury car manufacturer with motors for this application.
