ABSTRACT:
The invention is based on a system for controlling the braking action in a motor vehicle by means for adjusting the braking action independently of the driver's actuation. Upon recognition of a preselectable operating mode, for which at least the longitudinal velocity of the vehicle is found to be zero, a certain braking action is exerted. An operating mode of the type in question can be present when, for example, the above-mentioned creep suppression or the above-mentioned hillholding is desired. The core of the invention consists in that, upon determination of a preselectable longitudinal vehicle velocity during this operating mode, the braking action is increased independently of the driver. As a result of the monitoring of the longitudinal vehicle velocity according to the invention during the operating mode (creep suppression mode or hillholder mode), any motion of the vehicle unwanted by the driver is reliably prevented.
