Lane Keep Assist vs Lane Departure Warning are the ADAS (Advanced Driver Assistance Systems). The purpose of a lane departure warning is to alert a driver when they are changing their lane. It also tries to rouse a dozing driver. Most systems attain this through sounds such as buzzes and lights, including dashboard symbols.
Lane keep assist includes an actuator controlling the vehicle’s steering. As a result, lane keep assist attempts to guide a drifting vehicle back onto the road without the driver’s assistance.
Certain manufacturers refer to lane keep assist systems as lane keep or lane keeping. Whatever it’s called, the system is a step beyond lane departure warning and the first move toward automated steering.
