  • Patent number: 5373454
    Abstract: A pressure device control apparatus including a pressure source having a pump, and an accumulator connected to the pump and a pressure device, and a pressure detector for detecting the pressure in the accumulator; a normally-closed type solenoid valve interposed between the pressure device and the accumulator or a fluid tank; and a control unit having a drive control device for outputting a driving signal indicative of a command to operate the pump in response to a detection pressure detected in the pressure detector becoming equal to or less than a first predetermined pressure and a drive stopping signal indicative of a command for stopping the operation of the pump in response to the detection pressure becoming equal to or more than a second predetermined pressure which is higher than the first predetermined pressure.

  • Patent number: 5184695
    Abstract: The present invention is a method for controlling the change-over between two and four-wheel drive modes of a vehicle, wherein the two-wheel drive mode is smoothly changed to the four-wheel drive mode during acceleration in the two-wheel drive mode.

  • Patent number: 5174635
    Abstract: In a hydraulic braking pressure control system for a rear wheel brake wherein a control piston normally works to provide a hydraulic braking pressure control by cooperation with a cut-off valve interposed between an input chamber leading to a master cylinder and an output chamber leading to a wheel cylinder of the brake, the cut-off valve has a valve seat piston whose pressure-receiving area facing the output chamber is larger than the pressure-receiving area facing the output chamber. This ensures that opening and closing of the cut-off valve can be repeated in accordance with the output pressure from the master cylinder, so that the output pressure from the master cylinder can be reduced and applied to the brake wheel cylinder.

  • Patent number: 5100211
    Abstract: A hydraulic braking pressure control system which includes a sleeve slidably received in a housing with opposite ends facing an output chamber connected to a brake device, and a pilot chamber connected to a control hydraulic pressure source. A control piston is slidably received in the sleeve, with one end of the control piston facing the output chamber and the other end facing a control chamber connected to the control hydraulic pressure source through a lock valve which is adapted to be closed in response to the movement of the sleeve, in a direction to increase the volume of the output chamber. A cut-off valve located between an input chamber leading to a master cylinder and the output chamber includes a valve member having a maximum amount of movement in a seating direction which is regulated to a position of the valve member spaced apart from a valve seat when a valve seat member follows movement of the sleeve in a direction to reduce the volume of the pilot chamber to the maximum amount.

  • Patent number: 4982348
    Abstract: It is an object of the present invention to provide a method for controlling the vehicle speed during acceleration of a four-wheel drive vehicle, wherein the vehicle speed during acceleration can be determined with precision. According to the above method, even if a wheel is spinning, the vehicle speed can be correctly determined without any influence of the spin, by correcting the vehicle speed during acceleration by comparison of the determined second vehicle speed, based upon the lowest speed of the four wheels, with the first vehicle speed, which is determined based upon the wheel speed.
