driver assistance system (automotive) (DAS)
In modern motor vehicles, driver assistance systems (FAS), Driver Assistance System( DAS), are used to support the driver in driving the motor vehicle, but also in the comfort area and in infotainment. These systems support the driver by providing visual, haptic and acoustic information that warns the driver of potential dangers. There are various driver assistance systems designed to help reduce congestion, prevent critical driving situations, avoid accidents and mitigate the consequences of accidents.
Well-known examples are the electronic stability program( ESP), lane departure warning ( LDW), lane change assistant (SWA), traffic sign recognition( TSR) and light signal recognition, start-up assistant, night vision assistant, intersection assistant, which automatically detects crossing traffic such as cyclists, overtaking assistant, lateral guidance assistant, which supports the driver in maintaining the lane and changing lanes, traffic jam assistant, which relieves the driver in stop-and-go traffic, the Attention Assistant, which monitors the driver's attention, the Predictive Brake Assistant, which intervenes when emergency braking is imminent, and the various light assistants such as the Automatic Highbeam Assistant( AHB), which detects the headlights of oncoming vehicles, the adaptive light or the dynamic cornering light, which makes driving on winding roads easier. These and other driver assistance systems are supported by rearview camera, navigation, parking assist, blind spot monitoring, long-range radar( LRR) and short-range radar( SRR).
There are also driver control aids such as the head-up display, for telephone and radio operation, climate control, etc., which already use voice recognition. The sleep warning system, which records certain driver behaviors, is also part of the driver assistance systems.
Furthermore, driver assistance systems are about information and warning systems such as the pedestrian collision warning system, which alerts the driver to pedestrians, the collision warning system, which informs the driver about vehicles ahead, the tire pressure monitoring system, which shows the driver the tire pressure, or other systems such as car-to-car communication and car-to- infrastructure communication, which inform the driver about the friction coefficient of the road surface, about weather conditions along the route, about local traffic volumes, about traffic jams and accidents, and much more.
The classic driver assistance systems have mutated into Advanced Driver Assistance System( ADAS) with many driver-assisting functions through more advanced features. They form the prerequisites for automated driving systems, as defined in SAE levels 1 and 2, and for autonomous driving.
