Motor vehicle with an assistance system for changing lane or for keeping lane and parking assistance

摘要

The motor vehicle has a track switching or a track retaining assistance system with a monitoring unit that detects a range before or behind the vehicle. The parking assistance system (8) is activated during the journey by simultaneous switching on an operation of an ultrasonic sensor (10) with an enlarged detection area (15). The system works by the information provided by the ultrasonic sensors on the part of the track change or track retaining assistance system (2,6).
