摘要:
An apparatus and method are provided for operating a pump-less rear wheel anti-lock brake system of a vehicle using speed sensors on at least one front and one rear wheel, to provide a true dynamic rear proportioning (DRP) function, and to significantly enhance braking performance in rear wheel anti-lock mode through better management of the volume of pressurized fluid supplied by the master cylinder using rear pressure control (RPC).
摘要:
Apparatus including a brake control assembly having a brake fluid accumulator assembly. The brake fluid accumulator assembly includes a brake fluid orifice, at least one brake-fluid-accumulating piston bore, a controllable bi-directional motor, and at least one piston. The brake fluid orifice is fluidly connectable to a brake apply master cylinder and is fluidly connectable to a wheel brake. The at-least-one brake-fluid-accumulating piston bore is fluidly connected to the brake fluid orifice. The motor has a first motor driving direction and an opposite second motor driving direction. The at-least-one piston is each positioned in and slidable within a corresponding brake-fluid-accumulating piston bore and is each movable by the motor, in the first motor driving direction, to move in compression within the corresponding brake-fluid-accumulating piston bore.

摘要:
A control system for actuating a trailer braking system on a trailer is disclosed. The control system includes a trailer brake controller in communication with an antilock braking controller and an electronic stability controller of a towing vehicle to receive a wheel speed, a brake pressure, a yaw rate, a lateral acceleration, and a steering angle. The trailer brake controller utilizes the wheel speed, the brake pressure, the yaw rate, the lateral acceleration, and the steering angle to determine the attitude of the towing vehicle, and to calculate a desired braking force for the trailer. The trailer brake controller sends an appropriate output to actuate the trailer braking system on the trailer to stabilize the towing vehicle during extreme braking conditions.
