摘要： A method and system for braking a trailer with a trailer braking system including receiving, at a controller, a brake request from a vehicle. The controller receives wheel speed signals from wheel speed sensors on the trailer. The controller determines a velocity of the trailer based on the wheel speed signals and determines a wheel speed based on one of the wheel speed signals. The controller compares the velocity of the trailer to the wheel speed to obtain a difference value. The controller determines that one of the wheels is unstable when the difference value exceeds a threshold. When unstable and when the brake request is received, the controller generates a braking signal to reduce the braking force on the one of the plurality of wheels.

摘要： The invention relates to a method for adjusting brake pressures (P) at pneumatically operated wheel brakes of a vehicle, the brake pressure at the wheel brakes being adjusted in a normal braking mode (18) depending on a driver brake request (19). When an external brake request (30) independent of the driver brake request (19) is received, and/or when particular wheels tend to lock, the brake control unit (21) takes over the adjustment of the brake pressure (P) in a pressure control mode (24). In order to ensure a smooth and constant braking behaviour of the vehicle (2) when the brake pressure is adjusted in a pressure control mode (24) upon an external brake request (30), the brake control unit (21) continuously determines, in the pressure control mode (24), from measurement signals (34) supplied by wheel (5) speed sensors (29), at least one differential slip value (42) as the difference between the slip (38) of two axles (3, 4) of the vehicle (2) before releasing the control signals for the relevant pressure control valves (20). According to the evaluation, at least one control signal (31, 32) is adapted in order to bring the differential slip value (42) closer to the set differential slip value (53).

摘要： An open-loop brake control system (10) for an automated vehicle includes a brake-unit (26) and a controller (32). The brake-unit (26) varies brake-pressure (28) to operate brakes (30) of a host-vehicle (12). The controller (32) is in communication with the brake-unit (26). The controller (32) operates the brake-unit (26) to an initial-pressure (34) to initiate braking of the host-vehicle (12) in accordance with a brake-model (36) that characterizes vehicle-deceleration (38) versus the initial-pressure (34) based on a time-of-operation (40) of the brakes (30).
