Process and arrangement for constant speedkeeping through actuation of a motor vehicle's braking system.

摘要

The invention relates to a process and arrangement designed, through braking, to keep constant the speed of a motor-vehicle when travelling on downhill slopes. With the aim of producing simple actuation and deactuation of the constant speedkeeping function, the invention is characterized principally in that the constant speedkeeping function commences upon actuation of a driver-activated brake control (17). In connection with this, the lowest vehicle speed is stored as a target value within the memory of a control unit (1). The actual vehicle speed is then regulated towards the target value through activation of the vehicle brakes (4). Only once an ordinary driver-activated control (19) is activated, is the specified regulation towards the target value suspended.
