摘要： A flow control valve includes a sleeve formed with an inlet port and an outlet port and a spool slidably mounted in the sleeve. A fluid passage having an orifice connects a high-pressure end and a low-pressure end of the spool. An annular seal is liquid-tightly fitted in an annular groove formed in the inner periphery of the sleeve and extends into an annular groove formed in the outer periphery of the spool with a gap left therebetween. A biasing elements is provided to bias the spool in a direction opposite to the direction in which the fluid pressure differential between both ends of the spool tends to urge the spool. A seal can be effected by the annular seal and a shoulder portion of the spool defining the annular groove thereof. The seal, however allows fluid communication from the inlet port toward the outlet port through the orifice to be established with the movement of the spool.

摘要： A brake system having at least one static pressure line having a static pressure generator. The static pressure line has a bilateral driving piston having one end thereof acted on by a brake pressure and the other end acted on by a control pressure, a changeover valve capable of shutting off the fluid flow from the static pressure generator to the wheel brake, a flow control valve for controlling the control pressure of the driving piston, and an electronic control unit for giving a control command to the flow control valve. The driving piston is controlled so as to keep its predetermined neutral position while the manual input is zero, and, in a normal operation phase, so as to move in such a direction as to reduce the capacity of the static pressure line so that a manual control stroke will be shortened in a predetermined relationship with deceleration or with other braking factors closely associated with the deceleration. In an antilock control phase, the driving piston is controlled so as to move in such a direction as to increase the capacity of the static pressure line, after the fluid flow from the static pressure generator to the wheel brake has been shut off by said changeover valve.

摘要： An electronically controlled brake device for controlling a brake pressure according to a manual input. While the dynamic pressure line is functioning normally, the dynamic pressure acts on one end of a push rod associated with a brake pedal to give such a force as to counteract the control input to the brake pedal. If the dynamic pressure line fails, the push rod comes into contact with a dynamic pressure piston to transmit the control input force to a master cylinder. An electronic pressure control valve is provided to adjust the connection of the dynamic pressure source with a reservoir and with a dynamic pressure chamber in response to the commands of an electronic control unit so that its output pressure will be in a predetermined relationship with the pedal stroke. Thus in normal conditions, a desired deceleration is obtained with a shorter pedal stroke and in the failure of dynamic pressure, a minimum deceleration is obtained with a lighter pedal force.

摘要： An anti-lock brake control system for an automobile is provided with a master cylinder, a main fluid passage communicating between the master cylinder and at least one wheel brake, a recirculating passage branched off from the main fluid passage for recirculating a fluid medium back to the main fluid passage, a pump disposed in the recirculating passage for recirculating the fluid medium, a pressure regulator for reducing or increasing the brake pressure of the wheel brake and an anti-lock modulator for changing the area of the main fluid passage. The modulator is provided with a housing having a fluid chamber, a first port communicating with the master cylinder and a second port communicating with the pump, and with a movable element vertically movably accommodated in the fluid chamber. The movable element is normally located at a lower position in the fluid chamber by the gravity and moved upwards by the flow of the fluid medium discharged from the pump. The modulator is so constructed as to reduce the area of the main fluid passage when the movable element is moved upwards.

摘要： A wheel speed control system incorporating in-gear vibration detection and elimination means for use in a vehicle includes wheel speed detectors for detecting the speed of a wheel, a wheel speed control section such as an antiskid control and/or brake traction control, an in-gear wheel speed control section, and an in-gear vibration detector. When the speed of a drive wheel deviates excessively from the speed of the vehicle as measured by a non-drive wheel, the wheel speed control is operated to control the speed of the drive wheel to become nearly equal to the vehicle speed. A differential circuit is provided for taking a second order differential excess the reference level, indicating that the in-gear vibration is present, the in-gear vibration detector generates as in-gear vibration signal, which substitutes the in-gear wheel speed control for the wheel speed control to eliminate the in-gear vibration possibly caused by the wheel speed control.

摘要： A duty factor control method for electromechanical actuators which can take only mutually discrete positions. A required quantity of state R which is in intermediate condition between two discrete positions is given for every upper-level control cycle Tr. According to the R value, the durations Ta and Tb of first and second states (such as ON and OF positions) of the actuator are determined. In order to obtain the required R smoothly and quickly, the sum Tc=Ta+Tb has to be set as small as possible. But the Ta and Tb values have to be larger than their minimum values Tam and Tbm which are determined by the dynamic characteristics of the actuator. Thus, the Ta and Tb values are determined so that either Ta or Tb will be set at its minimum value Tam or Tbm while the other will take a value corresponding to R. Ta, Tb, Tam and Tbm are set as multiples of a unit cycle To so that the duration of state will be measured digitally for every unit cycle To by a counter. When it is judged that the duration of state has reached the preset value Ta or Tb, the state is changed over from one to the other. When the R value and thus Ta and Tb are renewed at the end of every cycle Tr, the state at the end of cycle Tr is maintained until its duration exceeds a renewed Ta and Tb value. Also, if necessary, either Ta or Tb may be set at zero so that one state will persist for the entire cycle Tr.

摘要： A wheel spin control apparatus for controlling the spin occurring on at least one of driven wheels of a vehicle by the application of a braking force to the driven wheel is disclosed. The apparatus includes a spin detector for detecting the spin of the driven wheel, a spin acceleration detector for detecting an acceleration of the spin, a calculator for calculating a control variable FUNC which is proportional to the sum of the spin and the spin acceleration. When the control variable FUNC exceeds above a first threshold located in a positive region, the braking force is increasingly applied to the driven wheels, and when the control variable FUNC exceeds below a second threshold located in a negative region, the braking force is decreasingly applied to the driven wheels.

摘要： A wheel spin control apparatus for use in an automotive vehicle having left- and right-hand driven wheels includes spin detectors for detecting the occurrence of an excessive wheel spin in the left- and right-hand driven wheels, and braking controllers for applying braking forces to the left- and right-hand driven wheels in response to the detection of the excessive wheel spins to suppress the excessive wheel spin, and thereafter gradually weakening the braking forces. The wheel spin control apparatus further includes a torque controller for controlling an output power of an engine employed to drive the left- and right-hand driven wheels such that the engine output power is gradually decreased as at least one of the braking forces is gradually weakened, whereby the suppression of the driven wheel effected by the braking controller is gradually taken over or superseded by the torque controller.
