On multi-lane motorways and urban roads, the system can help the vehicle maintain a steady position behind the vehicle ahead and stay in lane. This can noticeably improve driving comfort, e.g. on long journeys and in heavy city traffic.
Assistance functions included in adaptive cruise assist are adaptive cruise control and active lane assist. Adaptive cruise control helps accelerate, brake and maintain speed and distance. The active lane assist helps keep the vehicle in the lane. This can increase driving comfort, especially on long journeys.
Working within system limits, the system detects lane markings, roadside structures, vehicles in adjacent lanes and a number of vehicles travelling ahead. Based on this information, the system derives a virtual driving path within which it then guides the vehicle. The assistance of steering intervention helps keep the vehicle in the centre of the lane. At the same time, the set speed remains constant and the system controls the distance to vehicles ahead. It is necessary to maintain control of the vehicle at all times, as adaptive cruise assist responds only within system limits.
Adaptive cruise assist uses the radar sensor built into the front of the vehicle, the front camera and the ultrasonic sensors to permanently monitor the area at the front of and to the sides of the vehicle front end.
In addition, the system is supported by a steering wheel with hands-on-wheel detection in specific steering wheel design, which detects whether the driver has their hands on the steering wheel. In this way, the system checks whether the driver is paying the necessary attention.
Thanks to the many parameters accounted for, adaptive cruise assist makes it convenient to drive at speeds between 0 and 250 km/h and in congested traffic situations. An extended automatic restart takes place in traffic jams.
Adaptive cruise assist includes:
- adaptive cruise control
- active lane assist
