Abstract: A process and a device for controlling the brake system of a vehicle, in which in traction control and at the beginning of the control, a braking force build-up independent on the slippage takes place, which is stopped when a sizable braking effect is detected on the spinning wheel. Alternatively or in addition to this system, it is provided that, when the vehicle decelerates in active traction control, the braking force build-up pulses and/or the braking force decrease pulses are determined as a function of the measured slippage of at least one wheel, while outside these areas the pulses are determined so that the increase in braking force takes place in steps with the same change in the braking force.

Abstract: In a brake system with a controllable hydraulic pump in a hydraulic circuit, and with at least one solenoid valve, the operating state of the valve is changed in response to a control signal. As a result of the change in the operating state of the solenoid valve, the flow resistance in the hydraulic circuit is changed. Monitoring structure is provided which, in the presence of certain operating conditions, monitor the run-down behavior of the hydraulic pump in different operating states of the solenoid valve and actuate a display device to display a malfunction of the brake system when a malfunction is detected. Additionally, or alternatively, the automatic brake control can be turned off in reaction to the detection of a malfunction. It is possible for the control unit and the hydraulic unit to be replaced separately and for the installation to be tested for proper functioning.

Abstract: The invention relates to a safety system for a motor vehicle equipped with at least one braking system corresponding to a wheel unit. Furthermore, an automatic transmission system is provided which changes its ratio automatically based on specific shift criteria. A safety-relevant signal is generated in dependence upon a detection unit which detects states critical to safety of the brake system of the motor vehicle. According to the invention, the temperature of at least one brake system is applied for generating the signal relevant to safety. The shift criteria for the automatic transmission are changed in dependence upon this safety-relevant signal.
