Abstract: A vehicle speed control system can be activated so as to control the vehicle speed in a modified way in response to the driver's inputs. When activated, the accelerator 30 position defines a target speed and the speed controller 22 controls both the engine 34, via and engine control unit 36 and the brakes 14, 16, via a hydraulic brake control unit 20 so as to control the vehicle speed to the target speed. The acceleration of the vehicle is also controlled according to the difference between the present vehicle speed and the present target speed.

Abstract: A process is disclosed for adjusting the speed of a vehicle travelling on a gradient to a predetermined desired speed, wherein the vehicle is equipped with an ABS and/or ASR system, comprises determining the actual speed of the vehicle travelling on a gradient, determining a control deviation for the vehicle, the control deviation being the difference between the actual speed of the vehicle and the desired speed, and actively applying the brakes of the vehicle when the control deviation is greater than a predetermined amount. Only the brakes of the downhill axle are braked so long as the control deviation is less than a predetermined control deviation, or so long as the slip of the braked wheels are less than a predetermined slip. The brakes of the uphill axle are applied only if the predetermined control deviation is exceeded.

Abstract: Systems, methods, and apparatuses are provided for controlling a braking torque of a vehicle while travelling in an at least semiautomated manner. Standstill data is received, while the vehicle is traveling in the at least semiautomated manner on an incline and/or a decline, when a temporary standstill of the vehicle is requested by the assistance system. Speed values are continuously received that describe a speed of the vehicle while the vehicle is decelerating prior to the temporary standstill. Slope data is continuously determined that describes an angle of the incline or decline. An amended speed value is continuously computed that depends on the speed value and the slope data. An electronic control signal is output to control the braking torque to bring the vehicle to the temporary standstill when the amended speed value decreases below a predetermined threshold value and the standstill data are received.
