A system for multi-mode autobrake control may comprise a wheel speed sensor and a BCU electrically coupled to the wheel speed sensor. A tangible, non-transitory memory may be configured to communicate with the BCU and may have instructions stored thereon that, in response to execution by the BCU, cause the BCU to perform operations comprising receiving a wheel speed signal from the wheel speed sensor, inputting the wheel speed signal into an antiskid filter and a nominal filter, calculating an estimated aircraft deceleration rate, and determining an autobrake pressure command based on the estimated aircraft deceleration rate.

A test arrangement for functional testing of a brake control system in a vehicle, in which either a first parking brake system or a second parking brake system can be installed, wherein the brake control system has a control device with a first control module for controlling the first parking brake system, and has a second control module for controlling the second parking brake system, and wherein either the first control module or the second control module can be activated by means of a coding unit, in order to control the associated parking brake system, while the non-activated control module remains inoperative. The brake control system has a test unit with which a swap plausibility check can be carried out, which can be used to check whether the correct control module for the installed parking brake system is activated.

Accurately controlling pressing thrust regardless of an individual difference and a use situation of a brake apparatus, and the like are set forth herein. The present invention controls a motor that applies thrust to a piston that presses a brake pad, in a current variation period before an idling current period, a variation in the current and the voltage or a variation in a function including the current and the voltage in the idling current period is computed as a plurality of prospective values. At a predetermined time T0 during the current variation period, one of the plurality of prospective values is selected on the basis of the current and the voltage, and on the basis of the variation in the current and the voltage or the function related to the selected prospective value, a characteristic parameter of the motor is computed to compute a stop current of the motor.

Disclosed is a method, system, and computer readable medium including program instructions for controlling the braking of one or more vehicles in a vehicle system positioned for unloading/loading of cargo. The vehicle system includes a designated head-end and a tail-end and each of the one or more vehicles is equipped with an electronic braking system in communication with a central control via a communication network spanning across the vehicle system. A dynamic unloading/loading braking profile can be set on at least one electronic braking system on at least one vehicle. During unloading/loading of the cargo from one or more vehicles in the vehicle system, the braking on at least one of the vehicles in the vehicle system is controlled via the dynamic unloading/loading braking profile.

The invention relates to a method for carrying out a cleaning operation for at least one braking device of a braking system in a motor vehicle, said method having the following steps: setting a braking pressure by components of the braking device in accordance with a predefined braking pressure curve, wherein the braking pressure curve, during the cleaning operation, specifies braking pressures that vary over time for the braking device, correcting a setpoint motor torque that is to be provided by a drive motor of the motor vehicle and that is dependent on a braking effect brought about by the set braking pressure, the predefined braking pressure curve being selected such that a longitudinal deceleration of the motor vehicle, which is brought about by the predefined braking pressure curve, can be compensated for by a corresponding additional motor torque.
