摘要： Improvements in vehicle antilock braking systems of the type having an operator controlled master cylinder (11) and a second source (55, 57) of pressurized hydraulic fluid for selectively supplying rebuild pressure after an antilock event are disclosed. The improved system is selectively operable in one of three braking modes, a normal braking mode (119) where braking force is proportional to an operator brake pedal pressure, an enhanced anti-skid braking mode (69) where braking force may be maintained at a maximum nonskid level, and a conventional anti-skid braking mode (71) where braking force follows a cyclic pattern of fluid pressure bleed and build. The system includes circuitry (17, 19, 35, 37, 93, 95) for determining the speed of each wheel and an arrangement (59) operable independently of any vehicle wheels for determining vehicle deceleration. This comparison normally invokes the enhanced anti-skid braking mode. In the enhanced mode, the system is continually searching for an optimum wheel speed reference (39) by determining (119) on which side of the peak of a mu-slip curve the vehicle is operating, for example, by calculating the sign of the slope of the mu-slip curve at the current vehicle operating point, and then incrementing (88) a prior wheel speed reference by a value (79) which changes the wheel speed reference toward the peak (75) of the mu-slip curve thereby calculating an updated wheel speed reference to control appropriately the braking system. The accuracy of the determined vehicle deceleration, and in particular, of the accelerometer is confirmed by comparison (63) to an expected deceleration based on operator brake pressure, and the conventional anti-skid braking mode is substituted for the enhanced anti-skid braking mode in the event the determined vehicle deceleration is determined to be inaccurate. The enhanced anti-skid mode utilizes a pulse width modulated solenoid actuated two position valve (41, 43) operable in one position to provide a fluid flow path from the braking device, and in the other position to provide a fluid flow path from a second source to the braking device.

摘要： A vehicle powered by an electric motor which may be operated as a generator to effect regenerative braking of certain vehicle wheels in combination with individual friction brakes associated with other wheels. A commanded vehicle deceleration is apportioned among the wheels by determining the maximum regenerative braking deceleration achievable by drive wheels, and braking the vehicle occurs solely by regenerative braking so long as the commanded deceleration is less than the determined maximum deceleration. When a commanded deceleration exceeds the determined maximum, the regenerative braking is supplemented with friction braking of the other wheels while the maximum regenerative braking is maintained. The maximum regenerative braking of the certain wheels may be supplemented with additional friction braking of those same certain wheels, but this occurs only if the combined deceleration of the regenerative braking of the certain wheels and the friction braking of the other wheels is inadequate to achieve the commanded deceleration.

摘要： A distributor pump type fuel injection system for a diesel engine wherein the pump is driven by the engine and the control of the timing and metering of fuel being delivered to each cylinder of the engine is controlled by a single electromagnetic solenoid device. The control system includes a distribution head for distributing pulses of fuel to each cylinder, the control of the fuel to the cylinder, both metering and timing, being controlled by the above-mentioned single electromagnetic control device. The fuel system includes a metering chamber and a timing chamber, the two chambers being separated by a free piston. In the control system to be described, fuel is premetered into the metering chamber, the quantity of fuel therein being controlled by the duration of energization of the control valve during the metering portion of the cycle. The time of injection of the premetered fuel is similarly under the control of the control valve and is initiated upon energization of the control valve.

摘要： A vehicle antilock braking system having an operator controlled master cylinder for developing a first source of pressurized fluid and a second source of pressurized hydraulic fluid for selectively supplying rebuild pressure after an antilock event to simultaneously provide for actuation of each wheel braking device. A solenoid operated first flow control valve for each wheel controls communication of either the first source or second source of pressurized hydraulic fluid to the braking device and the braking device to a low pressure return. A hydraulically operated second control valve has a first inlet port connected to receive the first source of hydraulic pressurized fluid and a second inlet connected to receive the second source of hydraulic fluid and an outlet port connected to the first flow control valve. A bypass pressure regulator responsive to the first source of pressurized fluid and the second source of pressurized fluid supplies pressurized hydraulic fluid from the second source to each of the hydraulically operated second control valve when the operator controlled master cylinder supplies the first pressurized hydraulic fluid to the braking device. The pressure of the second source is directly proportional to the pressure of the first source and when sufficient to overcome a resilient member in the second control valve is supplied to the first valve to independently operate braking device.

The fluid carrying core (12) comprises: a magnetic armature (30) movable through a working gap (32) within a thin walled tube (34). The armature includes a first plurality of grooves (100) to permit fluid flow thereacross. The tube is joined to a magnetic first member (50) in a manner to form a leak-free seal (56) generally at one end of the tube. A second member (80) partially seals the other end of the tube and includes second flow means a second plurality of axial grooves (84) for receiving fluid carried to the valve (10) and for communicating same with the armature (30). Various passages are provided to carry fluid to and from the valve. The position and number of passages permit the valve to be used as a two-way valve or as a three-way valve passage means (88;64) for transporting fluid away from the valve (10).
