A braking systemfor use with an electric vehicleincluding an electric motor/generator assembly, and a conventional electrical energy storage device. Motor/generatorselectively drives wheelsof vehicle. The braking systemincludes a motor control modulewhich is communicatively coupled to motor/generatorand which selectively causes motor/generatorto provide a regenerative braking function at wheelsof vehicle. Braking systemfurther includes an antiskid braking system which selectively provides friction braking at wheelsandof vehicle. The braking systemis effective to detect antiskid braking events at each of the wheels, to selectively provide an antiskid braking function at each of wheelswhere the antiskid braking events are detected, and to selectively disable the regenerative braking function only when an antiskid braking event is detected at either of wheels

System and method for regenerative and antiskid braking within an electric vehicle

An instrument panel for a vehicle has an anti-lock braking system and a regenerative braking system. A method is used to control the brake system indicators on the instrument panel. If it is determined that an anomalous condition exists in either the anti-lock braking system or the regenerative braking system, a first indicator is illuminated in an amber color to alert the vehicle operator of this condition. If the anti-lock braking system is active, and there is no anomalous condition detected in the anti-lock braking system, a second indicator is illuminated in green to alert the vehicle operator that the anti-lock braking system is active. Control of the first and second indicators is provided in accordance with a hierarchal structure that gives priority to an anomalous condition in the anti-lock braking system.

Vehicle and method for controlling brake system indicators

The valve of the present invention includes a housing and a valve body. The valve body includes a key piece selected so that the valve may function as a normally-on valve or a normally-off valve depending upon the key piece selected. The valve of the present invention additionally includes a first ring and a second ring wherein each ring ensures proper supply of pressurized high flow rate media through the valve.

Control valve assembly

A retainer clip includes a retainer portion having an axially extending tubular wall which is radially expandable for snap-fitted radial engagement with a reduced diameter portion of a rod such that the retainer clip is radially and axially trapped on the reduced diameter portion of the rod and can only be removed by simultaneous application of dual directional forces. The retainer clip includes the retainer portion, a washer portion, and a hinge portion integrally connecting the retainer portion and the washer portion so that the retainer clip is handled as a single part during assembly onto the rod.

Retainer clip

A pressure regulator continuously actuates the relative axial position and the tangential position of an armature relative to a valve body into the desired position so as to deliver a fluid at a constant pressure. The tangential position of the armature is determined in response to an electrical excitation of a coil resulting in a change in the magnetic forces applied to the armature. The axial position of the armature is adjusted in response to changes in the control pressure. The armature has a plurality of ports which enable fluid to enter and leave therefrom. The valve body has a plurality of ports in fluid communication with the armature ports. The armature has two elongated prongs. A compression spring is generally centrally disposed within the electromagnetic compartment of the armature. One end of the spring is secured to the armature and the other end of the spring is secured to the regulator housing. The armature is movable rotatably relative to the regulator, the spring resisting the rotational movement of the armature. The armature is movable axially relative to the regulator, the spring resisting the axial movement of the armature. A washer is positioned within the housing and about the armature. A flux path is generated through the washer, the housing, and the armature as the electrical current is varied. The rotational position of the armature relative to the washer is varied in response to the change in the current.

Pressure regulator

A control valve assembly 10 having a pair of axially opposed seats 54, 56 is disclosed. A poppet 66 is disposed in a control chamber 58 between the seats. The poppet is movable between the seats to establish an average pressure in the control chamber. The poppet is a portion of an armature 28. In one embodiment, the armature is urged in a first direction by a solenoid and in the opposite direction by a spring 76 which extends between the armature and a housing of the valve. In another embodiment, means 310, such as diaphragms 312 or 314 or the slidable engagement 318, 320 between the housing 224 and the first end 251 of the armature are provided for radially positioning the armature as the armature is moved between the seats. In still another embodiment, the armature 228 is formed of a first section 416 and a second section 418 which are jointed by a shaft 434 which is slidable with respect to the first section.
