    摘要: An anti-skid control system for use in a motor vehicle includes a two-position type control valve for performing increase and decrease in the braking pressure supplied to a wheel braking cylinder for braking a wheel of the motor vehicle. The control valve is operated in accordance with a signal indicative of a duty ratio from an electronic control unit. The electronic control unit estimates a balanced duty ratio whereby the current braking pressure in the wheel braking cylinder is maintained as it is and determines the duty ratio on the basis of the estimated balanced duty ratio in accordance with the locking state of the wheel.

    摘要: In a wheel slip prevention control system for preventing the slippage of the driven wheel occuring when a vehicle is accelerated, a reference speed is derived from the non-driven wheel speed and the driven wheel speed is corrected by a correction value obtained as a function of a driven wheel acceleration value and a non-driven wheel acceleration value. The throttle valve is controlled with speed corresponding to the slipping condition of the driven wheel, i.e., with a control speed derived as a function of the reference speed and the corrected driven wheel speed, so that the slippage is quickly and effectively prevented.

    摘要: Disclosed herein is a vehicle running control device having a slip preventing function where a throttle opening degree of an engine is decreased upon occurrence of slip on drive wheels at starting and acceleration to prevent slip, and a running speed control function where a vehicle running speed is controlled to a target value. The control device comprises a common drive source for the above-mentioned both functions, a reduction mechanism for generating a drive output reduced discretely by driving the drive source in a predetermined direction and in a reverse direction, and link mechanism for effecting an open/close control of a throttle by the drive output. In the running speed control operation, the open/close control of the throttle is effected through the reduction mechanism and the link mechanism by intermittently controlling a driving operation of the drive source in the predetermined direction. On the other hand, upon occurrence of the slip on the drive wheels, the throttle opening degree is decreased to prevent the slip by intermittently controlling a driving operation of the drive source in the reverse direction through the reduction mechanism and the link mechanism. Further, the link mechanism is provided with a damper mechanism for damping a repulsive force to an acceleration operating section due to forcible decrease in the throttle opening degree in the slip preventing operation.

    摘要: A pressure control valve for use in an automobile braking system includes a spool slidably movable for providing selective fluid communication between a pressure fluid source, a wheel cylinder, and a reservoir. The spool has, or is associated with, a pressure-bearing member responsive to a fluid pressure from the wheel cylinder, for applying a first biasing force to the slidable member to urge the slidable member to a position in which the wheel cylinder and the reservoir communicates with each other. An electromagnetic coil responds to an electric signal for generating an electromagnetic force to urge the slidable member to the above position. The slidable member is normally biased by a spring under a second biasing force, greater than the first biasing force, to urge the slidable member to a position in which the pressure fluid source and the wheel cylinder communicate with each other. The fluid pressure in the wheel cylinder is regulated to cause the sum of the fluid pressure in the wheel cylinder and the electromagnetic force from the electromagnetic coil to counterbalance the second biasing force.

    摘要: An anti-locking control system for use in a motor vehicle having four wheels, comprising a hydraulic pressure supply system for applying a braking pressure from a master cylinder to two pairs of wheel-braking cylinders for braking the pair of wheels and a pump provided in common for the two pairs of cylinders in the hydraulic pressure supply system to decrease both the braking hydraulic pressures in each pair of wheel-braking cylinders. The hydraulic pressure supply system includes a pair of control valves each of which is arranged to have a first position at which the master cylinder is communicated with each of the pair of wheel-braking cylinders and a suction side of the pump is disconnected to the wheel-braking cylinder and a second position for disconnection to the wheel-braking cylinder and communication with the cylinder. Also provided in the control system an electronic control unit for effecting duty control of the pair of control valves so that the time periods at which the pair of control valves are at the second positions are not overlapped with each other. With this arrangement, although the pressure-decreasing is effected by one pump provided in common for the respective wheel-braking cylinders, it is possible to adequately effect the pressure-decreasing with respect to the lower-pressure side wheel-braking cylinder.

    摘要: A solenoid valve driving device includes a bypassing current path of which one end is connected to a point between a first switching device and a first solenoid valve and another end is connected to a point between a second switching device and a second solenoid valve, and an element disposed in the bypassing current path and having a characteristic that causes current to flow from the first switching device side to a second switching device side. By adopting the above described constitution, through current generated when the first switching device is switched from an OFF-state to an ON-state during duty control of the first switching device can be suppressed by the inductance of the second solenoid valve. In this way, one solenoid valve among a pair of the first and second solenoid valves, which is not operated, has a function of suppressing the through current.
