Abstract
A vehicle power steering apparatus for rotating a motor in response to a torque signal generated in response to a rotational torque of input and output steering shafts and for driving a steering direction control unit using a rotational force of said motor so as to perform power steering, comprising: vehicle velocity detecting means for detecting a vehicle velocity; rotational direction and rotational torque detecting means for detecting a rotational direction and a rotational torque of the input and output steering shafts in response to a signal generated by the rotational torque of the input and output steering shafts; controlling means for controlling the rotational direction of the motor in response to a detected rotational direction; and torque controlling means for decreasing the rotational torque of the motor in response to a detected vehicle speed signal when the vehicle speed is increased, and for increasing the rotational torque of the motor in response to the detected vehicle speed signal when a steering torque is increased.
