  • Patent number: 11364886
    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.

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.

  • Patent number: 10414387
    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.
