The main components of the LKS are a camera, a processor and a control unit. The camera continuously films the road markings. The information is transmitted and handled by the control unit, which is connected to for example the speedometer, braking signal and turn indicator. When a number of criteria are met that show that the truck unintentionally is steering off course, the control unit sends a warning signal.
The LKS is easily activated or de-activated with a switch on the instrument panel.
