<P>PROBLEM TO BE SOLVED: To provide a power steering apparatus capable of continuing a power steering function even if the voltage of a power source decreases and the rotating speed of a motor decreases. <P>SOLUTION: The power steering apparatus has a power steering function to drive an oil pump by a motor to generate hydraulic pressure, and to assist in driver's steering through the hydraulic pressure. The power steering apparatus includes a power source voltage detecting unit which detects the voltage of a power source of the power steering apparatus; a motor rotating speed detecting unit which detects the rotating speed of the motor; and a control stopping unit which stops the power steering function when the voltage of the power source detected by the power source voltage detecting unit exceeds a predetermined power source voltage value, and the rotating speed of the motor detected by the motor rotating speed detecting unit is equal to or less than a predetermined motor rotating speed value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
