  • Publication number: 20220315004
    Abstract: The disclosure is directed to a method for slip control of a vehicle wheel driven via an electric drive. The method including at least the following steps: driving the electric drive of the vehicle wheel using an actual drive torque in a torque control in a torque control step, determining a wheel speed and a wheel slip of the vehicle wheel and evaluating the wheel slip by way of an instability criterion as to whether an instability exists, upon recognizing an instability, direct or indirect transition in a slip control of the wheel slip to a setpoint slip by driving the electric drive, determining whether an end criterion for ending the slip control is satisfied; and, if the end criterion is satisfied, returning to the torque control in the torque control step.

  • Patent number: 11400906
    Abstract: An electropneumatic parking brake module (1) includes a supply connection (2), a spring-type actuator connection (4), an inlet-outlet valve unit (10) having a first switching position and a second switching position, and an electropneumatic pilot control unit (12) for outputting at least a first control pressure (p1) at the inlet-outlet valve unit (10). In the first switching position of the inlet-outlet valve unit (10), a spring brake pressure (pF) can be fed through directly from the supply connection (2) to the spring-type actuator connection (4) by virtue of the fact that the spring-type actuator connection (4) is connected to the supply connection (2), and, in the second switching position of the inlet-outlet valve unit (10), when the first control pressure (p1) is below a first threshold value, the spring-type actuator connection (4) is connected to a ventilating connection (14.3) of the inlet-outlet valve unit (10).

  • Patent number: 11292445
    Abstract: A method for operating an electropneumatic parking brake system of a vehicle combination, which includes a tractor vehicle and a trailer vehicle, includes activating, after a parking operation and braking of the vehicle combination, a trailer check function in a standstill state. The trailer check function enables a check as to whether, in the case of a decrease in the braking action of the trailer vehicle, the vehicle combination can be held in a stationary manner solely by way of the braking action of a parking brake of the tractor vehicle. The trailer check function is carried out automatically when a vehicle combination has been braked in a stationary manner independently by way of an automatic parking function.

  • Patent number: 8833868
    Abstract: A pneumatically-operated vehicle brake system has a first compressed air line in which compressed air at a controllable service brake pressure can be provided. Membrane parts of brake cylinders can be ventilated by the service brake pressure for a service brake function. A parking brake device includes a second compressed air line in which compressed air can be provided at a parking brake pressure electro-pneumatically. Brake cylinder spring brake parts can be ventilated by compressed air at the service brake pressure to provide a parking brake function. The parking brake device also has a ventilation inlet by which the second compressed air line can be ventilated to increase the parking brake pressure, and a first ventilation outlet by which the second compressed air line can be ventilated to reduce the parking brake pressure. The second compressed air line can be pneumatically connected to the first via the first ventilation outlet.

  • Patent number: 8794718
    Abstract: A valve unit for an electro-pneumatic brake control is connected to an input of an air-quantity-boosting valve for the aeration/venting thereof. A double-armature solenoid valve includes primary and secondary armatures each spring-loaded and actuated by a common magnet coil. The primary armature is a switch for a vent valve; the secondary armature is a switch for an intake valve. When the coil is not drawing current, the armatures are in spring-loaded position, the intake valve blocking intake and the vent valve venting. When a first current flows through the coil, the primary armature enters switching position, with the secondary armature in spring-loaded position; the intake valve blocking intake and the vent valve blocking venting. When a second current greater than the first flows through the coil, both primary and secondary armatures are moved into switching positions, so that the intake valve admits air and the vent valve blocks venting.

  • Patent number: 8795136
    Abstract: An actuating device includes a vehicle operating brake and parking brake. A first braking effect is generated by the parking brake independently of a braking procedure for the operating brake. The actuating device comprises a first switched state, wherein the first braking effect of the parking brake cannot be provided, and a second switched state, wherein the first (full) braking effect of the parking brake is provided. The actuating device further comprises a manually actuatable operating element for actuating the parking brake that comprises travel positions. The actuating device is switched to the second switched state in a first travel position when the parking brake is released, and to the first switched state when the parking brake is applied. Also, the actuating device is switchable to a further switched state. In an actuating method, the actuating device is switched to the further switched state in response to an actuation.

  • Patent number: 8708430
    Abstract: A pneumatic vehicle brake system includes first and second groups of wheel brakes belonging, respectively, to first and second brake circuits having first and second compressed air storage tanks for providing first and second stored pressures. At least one first circuit brake cylinder is a combined spring-store/diaphragm cylinder with a spring store part for providing a parking brake and a diaphragm part for providing a service brake. If the first circuit fails, the spring store part is deaerated to engage the parking brake. A pressure sensor for measuring the first stored pressure is connected to a control unit that controls a modulator for aerating and deaerating the spring store part. The control unit generates a signal for an electrically actuatable modulator solenoid valve if the value measured by the sensor falls below a minimum value, such that the spring store part can be aerated and deaerated via the valve.

  • Patent number: 8651588
    Abstract: An electro-pneumatic brake control device is provided for controlling the parking brake of a vehicle having compressed-air-actuated brake cylinders, at least one of which is a spring brake cylinder with a spring store part. Valve devices place the brake control device into various operating states. In a first operating state, the valve devices are at least partially supplied with current and switched such that a compressed air line to the spring store part of the spring brake cylinder is aerated. In a second state, the valve devices are at least partially supplied with current and switched such that the compressed air line is deaerated. In a third state, which can be activated in the event of failure of the electrical energy supply of the brake control device, the valve devices are switched to a currentless state such that the compressed air line is automatically deaerated in throttled manner.
