Abstract
A method and a device are for setting the longitudinal speed of a vehicle to a setpoint speed, in particular on the basis of a regulation, having controllable brakes. In operation of a cruise control system, the cruise control may be activated when the instantaneous driving speed is significantly higher than a stored setpoint speed. In this situation, there may be unwanted braking responses by the regulator, which may endanger the driver and the following road users. In such a situation, the method prevents a breaking measure from being implemented and ensures that the vehicle will coast, being braked only by the road resistance and the drag on the engine, until reaching the set speed. The driving response of the cruise control system approximates that of a human driver, so the responses of the automatic cruise control seem more intelligible for the driver.
