  • Patent number: 10538227
    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.

  • 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.

  • Patent number: 10239505
    Abstract: A method for controlling a vehicle deceleration in a vehicle with an ABS brake system. The method includes detecting a target vehicle deceleration specified by a driver; defining a maximum deceleration and a minimum deceleration, each depending on the detected target vehicle deceleration; detecting an actual vehicle deceleration; and controlling a braking pressure on wheel brakes of a first vehicle axle and a second vehicle axle depending on the detected actual vehicle deceleration by actuation of ABS brake valves. Controlling the braking pressure by the actuation of the ABS brake valves comprises controlling the braking pressure on the wheel brakes of the second vehicle axle depending on a detected actual differential slip if the actual vehicle deceleration is less than the maximum deceleration and greater than the minimum deceleration, wherein the actual differential slip indicates the difference in a rotational behavior of the first vehicle axle.
