Abstract: A brake control system and method for motor vehicles is provided with an electronic control unit, by which, when the motor vehicle is stationary, a parking brake function can be activated manually or automatically. Its deactivation occurs upon reaching a predefined release condition. In the presence of a release condition the brake pressure, which was built up for the parking brake function, is released in a time offset manner at least in relation to the axles of the vehicle by way of the control unit.

Abstract: A brake system of a motor vehicle can activate a brake when an activation condition exists. The braking effect is reduced when a deactivation condition exists. It is suggested that at least one property of the reduction of the braking effect, e.g., the duration or the gradient of the reduction, be at least temporarily a function of a longitudinal inclination of the motor vehicle.

Abstract: A method is provided for operating a hold function for temporarily holding an operationally ready motor vehicle in a stationary state by use of a service brake. The service brake is actuated by electrohydraulic, electropneumatic or electromechanical mechanisms. The service brake can be activated within the framework of the hold function, when the speed of the vehicle is less than a preset first speed threshold, and the presence of the driver in the driver's seat is detected. The presence of the driver in the driver's seat is detected as a function of the signal of a flap sensor for detecting an opened or closed position of the flap, assigned to this flap sensor.

Abstract: A brake regulation system for motor vehicles is provided with an electronic control unit, by which an automatic parking brake function can be activated in the stationary phase of the motor vehicle and can be deactivated upon reaching a predetermined triggering condition. The control unit can determine in a wheel selective manner the coefficient of friction, or rather the adhesion between the tires and the roadway at the location of the motor vehicle, which is held so as to be stationary by use of the parking brake function. In the presence of different coefficients of friction or adhesion coefficients at the right and left wheel of at least one driven axle, the triggering condition is adapted in the direction of a longer hold of the brake pressure.

Abstract: A brake regulating system for motor vehicles is provided having an electronic control unit, by which an automatic parking brake function is activatable at a standstill of the motor vehicle, whose deactivation is performed as a function of the instantaneous drive torque, is implemented in such a way that in the event of activated parking brake function, a deactivation of the parking brake function may be suppressed if, on the basis of a function executed at a standstill of the motor vehicle, an automatic increase of the drive torque which does not result from a starting command of the driver is necessary.

Abstract: A process and device for controlling the brake system of a motor vehicle with all-wheel drive are described. The process and the device include an electronic control unit which controls at least one coupling unit for engaging and disengaging an all-wheel drive, so that at least one wheel can be decoupled, from the drive. After stopping the motor vehicle, for example on a sloping roadway, a predefined brake pressure on at least one wheel of the motor vehicle is held either depending on or independently from the extent of brake pedal actuation. The brake pressure is held until a brake pressure reduction condition is present, such as during a brake pressure holding time. During that time, the brake pressure on at least the one wheel is reduced and the wheel is decoupled from the drive to detect slippage, while at least one other wheel remains pressurized with brake pressure.

Abstract: A method of stabilizing a vehicle in the event of a loss of tire pressure is provided. A driving-stability-related system, which can be manually activated and/or deactivated, is automatically activated when a loss of tire pressure is determined or when the tire pressure is below a defined threshold. The driving-stability-related system preferably remains deactivated when it was manually deactivated again after an automatic activation, at least for a given ignition-cycle.

Abstract: A method for monitoring the thickness of at least one friction partner of a vehicle friction brake, especially the brake linings of a vehicle braking system; for each braking action, the actuating time, the applied braking pressure, the relative speed between the brake lining and the moving brake element, as well as the prevailing temperature in this region, being taken into account in a wear model in such a manner, that the wear determined by the wear model is subtracted from a starting thickness of the friction partners, in particular, the brake linings, and each wheel of the vehicle being monitored individually. A preferred polynomial formulation is specified for the wear model. In the brake lining, at least one wear stamp can also be provided, upon reaching which the current, existing brake lining thickness and/or the polynomial formulation may be appropriately corrected.
