___ Camera-based driver support systems (KAFAS) Depending on the options fitted, various camera-based systems are available. Technical implementation is realised with a camera in the mirror base and a control unit, the KAFAS control unit. The display functions of the camera-based driver support systems are: Lane departure warningHigh-Beam Assistant (not permitted in Japan)Speed limit ( Speed Limit Info)Collision warningOvertaking banNew: Urban traffic accident preventionNew: Preventive pedestrian protectionNew: Traffic jam assistant___ Urban traffic accident prevention The camera monitors the area in front of the vehicle. The camera uses image processing to detect every vehicle (passenger cars, trucks, motorbikes) within visual range, including stationary vehicles. Based on the positions, distances and relative speeds calculated, the warning is output or braking is triggered. This function warns the driver of critical collision situations and thus prevents rear-end collisions. The brakes are also applied automatically at speeds between 3 and 60 km/h, which reduces the consequences of an accident. Accidents can be avoided up to a speed differential of approx. 18 km/h. The function is available during both day and night. The collision warning is emitted in two stages. The first stage (pre-warning) shows the warning symbol in the instrument cluster (KOMBI). The symbol flashes in the 2nd stage (acute warning). Additionally there is an acoustic warning. Both stages can be switched on or off using the assist system operating facility. The function is always available when the vehicle is started. The pre-warning can be set on the central information display (early, medium, late). Shortly before a collision the brakes are applied automatically with a medium brake force in order to reduce the severity of the impact. When an acute warning is output, the brakes are prepared to deliver emergency braking as quickly as possible. ___
