PURPOSE:To obtain a power steering equipment with a stable steering force by using the load data detected while parking or running at an extremely low speed as the load data during the travel. CONSTITUTION:The load level at the time when a state is judged that the car speed is not generated for a predetermined time or longer and the load is not changed for a predetermined time or longer is stored in memory, and this value is used during the travel to control a power steering device. The steering force is prevented from being changed by apparent load changes due to the ruggedness of the road surface, and also no time delay is generated to follow the steering force. A load sensor is constituted with link mechanism 103, 104, a clyinder 106, photo-interrupters 3a, 3b, etc. |
