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).
A pump-less anti-lock brake apparatus for controlling the rotational speeds, during a braking cycle, of only the rear brakes of a vehicle having at least one front and one rear wheel and front and rear brakes acting on the front and rear wheels respectively, the apparatus comprising:
A rear brake pressure control (RPC) apparatus for a rear brake hydraulic circuit including a fluid storage element and a master cylinder supplying a volume of pressurized brake fluid to the rear brakes during the braking cycle in a pump-less anti-lock brake apparatus controlling the rotational speeds, during a braking cycle, of only the rear brakes of a vehicle having at least one front wheel and at least one rear wheel, and front and rear brakes acting on the front and rear wheels respectively, the RPC apparatus comprising:
A method for controlling a rear brake hydraulic circuit having a fluid storage element and a master cylinder supplying a volume of pressurized brake fluid to the rear brakes during the biting cycle in a pump-less anti-lock brake apparatus controlling the rotational speeds, during a braking cycle, of only the rear brakes of a vehicle having at least one front wheel, at least one rear wheel, and front and rear brakes acting on the front and rear wheels respectively, the method comprising:
A method for providing rear pressure control (RPC) for controlling a rear brake hydraulic circuit having a fluid storage element and a master cylinder supplying a volume of pressurized brake fluid to the rear brakes during the braking cycle in a pump-less anti-lock brake apparatus controlling the rotational speeds, during a braking cycle, of only the rear brakes of a vehicle having at least one front wheel, at least one rear wheel, and front and rear brakes acting on the front and rear wheels respectively, the method comprising:
A method for providing dynamic rear proportioning (DRP) for controlling a rear brake hydraulic circuit having a fluid storage element and a master cylinder supplying a volume of pressurized brake fluid to the rear brakes during the braking cycle in a pump-less anti-lock brake apparatus controlling the rotational speeds, during a braking cycle, of only the rear brakes of a vehicle having at least one front wheel, at least one rear wheel, and front and rear brakes acting on the front and rear wheels respectively, the method comprising:
