摘要： An improved electro-hydraulic brake system (10) having features for improving the pedal feel of the system, while further having design features which contribute to the economy of manufacture of certain components of the system. The system provides for an electrically powered normal source (42) of pressurized hydraulic brake fluid, and a manually powered backup source (12) of pressurized hydraulic brake fluid to the vehicle brakes in the event of failure of the normal source. During normal braking, fluid from the backup source is redirected from the vehicle brakes to a pedal simulator. The pedal simulator (26) preferably includes arrangements of spring loaded pistons, expansion volumes, and damping orifices, together with valves selectively controlling the flow of fluid to and from the pedal simulator which provides for an improved pedal feel during vehicle braking. The brake system of the invention further includes a relatively low cost fluid separator unit which is provided which prevents intermixing of pressurized fluid between the backup source and the normal source. The fluid separator unit acts to permit the normal source to act upon the hydraulic brake fluid to the backup source to operate the vehicle brakes. The fluid separator unit is preferably embodied as a piston having two working faces, each of the same diameter.

摘要： An anti-lock brake system having a switchable orifice control valve (22) disposed between the master brake cylinder (16) and the brake assembly. The switchable orifice control valve, having a valve body, a stationary member, a movable member and a solenoid coil actuated armature. The switchable orifice control valve (22) has a normally open state, a closed state and a third state during an anti-lock mode of operation. In the third state the brake fluid from the master brake cylinder to the brake assembly flows through a calibrated re-apply orifice (38) which controls the rate at which the pressure of the fluid being applied to the brake assembly is increased at a predetermined rate. The switchable orifice control valve is held in the third state by a pressure differential orifice between the input and output ports of the switchable orifice control valve.

摘要： A copy valve (10) for an anti-lock brake system. The copy valve (10) has a housing (110, 172) enclosing four chambers (114, 116, 112, 118; 188, 202, 190, 196). A first (114, 188) and fourth (118, 196) chamber of the enclosed four chambers receives pressurized fluid directly from the first and second cylinders of a dual master brake cylinder (18). The third chamber (112, 190) receives the pressure of the (electronically) controlled brake actuator (28) while the second chamber (116) is connected to the uncontrolled brake actuator (36). In one embodiment, a single piston (178) is enclosed in the housing (172) and the first (188) and second (202) chambers are disposed at the opposite ends of the piston (178). The piston (178) has an enlarged collar (179) intermediate the two ends which is received in an annular recess (177) provided in the housing (172). The third chamber (190) is formed between a first face (194) of the piston's enlarged collar (179) and the annular recess (177) while the fourth chamber (196) is formed between the opposite face (198) of the piston's enlarged collar (179) and the adjacent face (200) of the housing (172). A throughbore (214) is provided through the piston (178) connecting the first (188) and second (202) chambers. A valve (218, 220) disposed in the throughbore (214) is open when the piston is in the second chamber (202) and closed when the piston is displaced from the second chamber (202). In another embodiment, the copy valve (10) comprises two separate pistons (140, 150) each interacting with a valve element (146; 158, 162).

摘要： Methods for brake pressure control in a vehicular antilock brake system wherein brake pressure is restored to within a window of peak brake pressure after a reduction in pressure in response to a forced departure during vehicle braking. In a preferred embodiment, the pressure reduction is adaptively controlled. The vehicle has a plurality of wheels and each wheel has brake. The method includes increasing brake pressure at a wheel so as to attain a prereduction peak brake pressure, and initiating a pressure reduction mode of operation wherein brake fluid flows from the brake of the wheel. The method also includes restoring the brake pressure at the wheel to the desired brake pressure after termination of the pressure reduction mode of operation without making actual brake pressure measurements.

摘要： A stability control system of a vehicle utilizing an electronic control unit that minimizes rollback of a vehicle as a result of wheel slip immediately following a hill start assist operation. The electronic braking control module controls actuation and de-actuation of vehicle brakes on an inclined surface. Immediately following a hill start assist operation on the inclined surface after each wheel brake is de-actuated for allowing forward movement of the vehicle up the hill, a split-mu road surface condition is detected in response to sensing wheel slip for each of the wheels. The electronic control unit determines a respective undriven, or non-dominant driven, wheel having the highest coefficient of friction among the undriven, or less dominant driven wheels, as determined by the wheel speeds. The electronic braking control module actuates the vehicle brake of the undriven, or less dominant, driven wheels having the highest coefficient of friction relative to a tire/road surface interface for reducing rollback of the vehicle. The braking of the undriven, or less dominant, driven wheel is in addition to any standard stability control braking that may already be occurring.
