Abstract: A method for electronically setting the brake force distribution of a desired total braking force in partial braking forces to the axle of a motor vehicle in dependence on the differential slip is provided. The differential slip is detected as the difference of the slip values of a variable representing the slip at the respective axle and is assigned to a relevant pair of axles. One of the axles is selected as a reference axle and the respective differential slip of a pair of axles is determined as the difference of the slip value at the reference axle and of the respective slip value of one of the further axles.

Abstract: A method for determining the overall-deceleration values is attainable by actuation of wheel brakes, of a utility vehicle or of a vehicle combination with several axles. For the purpose of implementing a deceleration request in the course of partial brake applications, a braking-force distribution with braking forces distributed unequally to brake units with the wheel brakes of one or more axles is undertaken. In each instance one of the brake units is selected and a larger braking force is imposed via this selected brake unit than via the other brake units. A current deceleration of the utility vehicle or of the vehicle combination is measured or ascertained and is assigned as partial-deceleration value to the respectively selected brake unit and stored and the attainable overall-deceleration values are determined as the sum of the partial-deceleration values of all the brake units.

Abstract: A method for monitoring an implementation of an assistance braking specification, requested in an automated fashion by a brake system in a vehicle includes: detecting whether an assistance braking specification which is requested in an automated fashion is present; detecting an actual dynamics variable, the actual dynamics variable including wheel dynamics of at least one wheel of the vehicle and/or of a trailer, the actual dynamics variable being assigned to a wheel which is to be braked as a result of the assistance braking specification which is requested in an automated fashion; determining a reference dynamics variable, the reference dynamics variable including driving dynamics of the vehicle and/or of the trailer; and comparing the actual dynamics variable with the reference dynamics variable. When an assistance braking specification is present: a faultfree implementation of the assistance braking specification which is requested is detected if the actual dynamics variable deviates.

Abstract: A method for controlling a vehicle deceleration depending on a differential slip between two vehicle axles in a vehicle with an ABS brake system includes detecting at least one of a target vehicle deceleration specified by the driver and an actual vehicle deceleration; and controlling a braking pressure on wheel brakes of a vehicle axle to be controlled by actuation of ABS brake valves in such a way that the braking pressure on the wheel brakes of the vehicle axle to be controlled is controlled depending on a detected actual differential slip, so that the actual differential slip corresponds to a target differential slip. The actual differential slip indicates a difference in a rotational behavior of the vehicle axle to be controlled relative to a further vehicle axle. The target differential slip is dependent on at least one of the detected actual vehicle deceleration and the detected target vehicle deceleration.

Abstract: A brake valve for a compressed air brake system of a utility vehicle includes a compressed air input configured to connect to a system pressure, a compressed air output configured to connect a brake control line, and at least one sensor configured to determine a brake valve actuation travel of an actuating element of the brake valve with a working interconnection to the brake pedal. The brake valve further includes a characteristic curve memory storing two stored characteristic curves and/or dependences and at least one determination device. The brake valve is configured to output at least two useful sensor signals, a first of which represents a brake valve output pressure and a second of which represents a percentage actuation position of the actuating element. The at least one sensor is configured to generate an actuating signal depending on the brake valve actuation travel of the actuating element.

Abstract: A method for controlling a vehicle deceleration in a vehicle comprising an ABS braking system includes detecting a setpoint vehicle deceleration predetermined by a driver; establishing a maximum deceleration and a minimum deceleration, in each case as a function of the detected setpoint vehicle deceleration; detecting an actual vehicle deceleration; and controlling a brake pressure at wheel brakes of a vehicle axle to be controlled as a function of the detected actual vehicle deceleration by controlling ABS brake valves. Controlling the brake pressure at the wheel brakes of the vehicle axle as a function of the detected actual vehicle deceleration comprises: increasing the brake pressure at the wheel brakes when the actual vehicle deceleration is less than the minimum deceleration, and limiting the brake pressure at the wheel brakes when the actual vehicle deceleration is greater than the maximum deceleration.
