  • Patent number: 7357215
    Abstract: A controller controls right and left wheel drive motors based on a tire angle detected by a tire angle sensor such that the angular velocities of a pair of drive wheels about the center of a turn of the vehicle are equal to each other. The controller determines a steering speed of a steered wheel at the time a steering wheel is turned, from the tire angle detected by the tire angle sensor. Based on the steering speed, the controller controls a hydraulic pressure control motor, enabling a hydraulic pump to supply working fluid at a rate corresponding to the steering speed through a priority valve to a steering cylinder. With this arrangement, the vehicle is allowed to make a smooth turn.

  • Patent number: 6695567
    Abstract: A hydraulic device for industrial vehicles. A first motor drives a first hydraulic pump and a second hydraulic pump. The first hydraulic pump supplies hydraulic fluid to a power steering device and a brake device. The second hydraulic pump supplies hydraulic fluid to a carriage device. If an increased amount of hydraulic fluid need be supplied to the carriage device, a second motor drives a third hydraulic pump. Thus, together with the second hydraulic pump, the third hydraulic pump supplies hydraulic fluid to the carriage device.

  • Patent number: 6484081
    Abstract: A steering wheel angle sensor detects the rotational speed of a steering wheel. A wheel angle sensor detects the off-center angle of a wheel. A controller drives a motor based on the outputs of the steering wheel angle sensor and the wheel angle sensor. An oil pump generates an oil pressure according to the revolution speed of the motor. A steering valve determines the supply direction of hydraulic fluid to be supplied to a PS cylinder. The PS cylinder changes the angle of the wheel according to the given oil pressure.
