摘要： In an electric power steering system for a vehicle that controls a force that urges a steering wheel toward a neutral position thereof, a control unit (21) for the system is configured such that an electric motor (9) for providing an assisting force produces a relatively large returning force when a rotational direction of a steering wheel (2) agrees with a direction of the steering torque applied to the road wheel (7), and a relatively small returning force when a rotational direction of the steering wheel disagrees from a direction of the steering torque applied to the road wheel. Thereby, the effort required for a vehicle operator to steer the vehicle is reduced and the steering feel can be thereby and otherwise improved while providing a favorable returning force that urges a steering wheel toward a neutral position.

摘要： An electric power-assist steering system that provides a steering assist control in accordance with the steering angle right after the idle stop to reduce an unpleasant steering feeling and is installed in a vehicle having an idle stop mechanism (engine controller) that automatically performs an idle stop operation in a predetermined condition. The electric power-assist steering system includes a torque sensor, a steering angle sensor for detecting a steering angle relative to a midpoint of a steering angle that is learned, an electric motor whose assist force is controlled based on the steering torque and the steering angle, and a resolver for detecting a rotational angle of the electric motor. A steering angle right after the idle stop is determined based on the steering angle detected by the steering angle sensor right before the idle stop and variation in the rotational angle detected by the resolver during the idle stop.
