  • Patent number: 10889274
    Abstract: A method for electronically controlling a vehicle deceleration of a brake slip-controlled vehicle comprising a pneumatic braking system includes detecting that at least one wheel of the vehicle has a brake slip that exceeds a setpoint brake slip; in response to detecting that at least one of the wheels of the vehicle has a brake slip that exceeds the setpoint brake slip, brake slip-controlling the at least one wheel in order to prevent a lockup of the at least one wheel; determining a braking effect caused by wheel brakes on the wheels of the vehicle; and adjusting brake pressures output at the wheel brakes of one or more non-brake slip-controlled wheels in order to adjust the induced braking effect. The brake pressures at the wheel brakes of all non-brake slip-controlled wheels are adjusted.

  • Patent number: 10688978
    Abstract: A method for adjusting brake pressures on pneumatically operated wheel brakes of a motor vehicle includes setting, in a normal braking mode, a brake pressure depending on a driver brake request determined by the driver of the motor vehicle and a control unit, during reception of an external brake request which is independent of the driver brake request, in a pressure control mode, sets a resulting brake pressure at the respective wheel brakes taking into account the external brake request and the driver brake request. The method further includes terminating, after revocation of the external brake request, the pressure control mode depending on a comparison of a value representing the driver brake request and entered into the control unit with a predefined threshold value.

  • 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.

  • Publication number: 20190315324
    Abstract: A method for adjusting brake pressures at pneumatically actuated wheel brakes of a vehicle includes receiving an external braking demand. The method further includes, in response to the received external braking demand, performing, during each of a plurality of computation cycles: (i) ascertaining control signals for pressure control valves of the pneumatically actuated wheel brakes of the vehicle, (ii) continuously ascertaining a differential slip value, wherein the differential slip value is a difference between a slip of two axles of the vehicle and is determined by measuring signals supplied by speed sensors of wheels of the vehicle, (iii) evaluating the differential slip value with respect to a predefined or adjustable setpoint differential slip value, (iv) based on the evaluation of the differential slip value, adapting the ascertained control signals, and (v) releasing the adapted control signals to the pressure control valves.

  • 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: 10293801
    Abstract: A method for the adaptive control of a driver operation-dependent actual vehicle deceleration in a commercial vehicle includes determining an operating variable that indicates a displacement of a brake pedal of a brake valve demanded by the driver as well as an assistance deceleration demand, providing a mass-dependent feeling curve that associates a driver's deceleration demand with the operating variable, adapting the mass-dependent feeling curve if there is no assistance deceleration demand so that the determined operating variable is associated with an actually prevailing actual vehicle deceleration, specifying a target vehicle deceleration depending on a driver operation-dependent driver's deceleration demand determined from the corresponding feeling curve and the assistance deceleration demand if there is an assistance deceleration demand, and actuating a brake pressure corresponding to the target vehicle deceleration for adaptively adjusted, driver operation-dependent control of the actual vehicle dece

  • Patent number: 10279788
    Abstract: A method for adjusting brake pressures on pneumatically operated wheel brakes of a motor vehicle includes adjusting, in a normal braking mode, the brake pressures depending on a driver brake request; and adjusting, by a control unit in a pressure control mode, the brake pressures at the respective wheel brakes during reception of an external brake request, which is independent of the driver brake request and defined for the control unit as an external target deceleration value, as a function of a resulting target deceleration value of the vehicle deceleration. The control unit determines the resulting target deceleration value by linking the external target deceleration value according to the external brake request and a value corresponding to the driver brake request. A braking power index is determined which quantitatively represents the braking effect of the wheel brakes, and is provided to be taken into account in pressure control mode.
