Abstract: In an electric power steering system, when a motor rotation angular speed ? and a motor rotation angular acceleration ? of a steering assisting motor both exceed corresponding predetermined values ?s and ?s, respectively, an abnormal external force application-determining section determines that an external force equal to or greater than a predetermined value is applied to a steering mechanism, and sets an abnormal external force application determination flag (FLG) to 1. When the abnormal external force application determination flag (FLG) is 1, a d-axis electric current command value-calculating section activates a motor rotation angular speed-reducing section and performs field-strengthening control based on a motor rotation speed/d-axis electric current command value map.

Abstract: A recess is formed in a substrate. A bare chip, i.e., a light-emitting diode, is installed in the recess and connected to conductive members on the substrate with leads. A light-guiding layer composed of a light-guiding elastomer is disposed on the surface of the substrate.

Abstract: A first system and a second system include a first motor and a second motor for driving a steering mechanism in dependence on the rotational manipulation of a steering wheel. A first ECU and a second ECU mutually monitor abnormalities of the systems each to stop an abnormal system. When the respective systems are normal, the first ECU and the second ECU drivingly control the first motor and the second motor of their own systems to drive the steering mechanism by cooperation of the respective motors. When either one of the both systems is abnormal, the ECU of the other system solely drivingly controls the motor of its own system thereby to drive the steering mechanism. Thus, it can be realized to make the systems low in cost irrespective of the provision of the plural systems.
