<p>PURPOSE:To prevent the change of the restoration force of a steering by providing a restoration force correcting control part to correct and control a return direction motor current command value transmitted from a restoration force command part, in a control device for a motor-operated power steering device with which a rear wheel steering operation device is located in juxtaposition. CONSTITUTION:A return direction motor current command value outputted from a return torque valve command part 22 based on a detecting steering angle signal from a front wheel steering angle sensor 21 is inputted to a multiplication computing part 33 of a restoration force correcting control 3. A detecting steering angle from a rear wheel steering angle sensor 4 is converted into a front and rear wheel steering angle with a code responding to a phase in a front and rear wheel steering angle by a rear wheel state deciding part 31. A multiplying factor set part 32 sets a signal being 0 to 1 and sets a correction multiplier which is decreased to a value lower than 1 with the increase in a positive value and is increased to a value higher than 1 with the increase in a negative value. A multiplication control part 33 outputs an assist torque command value by multiplying a signal inputted from a torque value indication function part 22 by the correction multiplier to control a motor 6.</p> |
