Abstract
A method of reducing the travelling speed of a vehicle which has a multi-cylinder, piston-type internal-combustion engine, a variably controllable valve drive and a collision avoidance system includes the following steps: continuously determining, by the collision avoidance system, an actual distance between the vehicle and a vehicle ahead and comparing the actual distance with a speed-dependent minimum safe distance; and braking the vehicle by switching over at least one of the engine cylinders to a compressor operation when the actual distance falls below a minimum safe distance.
