The electric motor has an output shaft extending along a second axis extending generally parallel to the first axis. A first gear is rotatable about the second axis with the output shaft of the motor. A second gear in meshing engagement with the first gear is rotatable about a third axis extending transverse to the second axis. A third gear is rotatable with the second gear about the third axis. A fourth gear in meshing engagement with the third gear is rotatable with the steering member relative to the housing.

A vehicle control system includes a steering operation element configured to receive a steering operation of a vehicle by a driver, a grip detector configured to detect a gripping state of the steering operation element by the driver of the vehicle, a traveling controller configured to perform traveling control related to steering and acceleration or deceleration of the vehicle, and a determiner configured to determine on the presence or absence of execution of the traveling control or the degree of execution of the traveling control based on the gripping state.

A circuit substrate (3) is provided with first and second rigid parts (11, 12) having six metal foil layers, and a thin flexible part (13) having two metal foil layers connecting the two rigid parts. A ground wiring (51) which is shaped like a wide strip is formed on the surface metal foil layer, and a plurality of inter-rigid-part wirings (55) are formed on the inner metal foil layer in parallel lines. Outer edges (51a) of the ground wiring (51) are positioned closer to side edges (13a) of the flexible part (13) than to the inter-rigid-part wirings (55). The ground wiring (51) protects the inter-rigid-part wirings (55) from cracks.

An electronic control device includes a control command generation unit that generates and outputs a control command for controlling a first control object; a communication unit that performs communication with another electronic control device that controls a second control object; a communication abnormality determination unit that determines whether communication with the another electronic control device by the communication unit is abnormal; and a reset determination unit that determines whether the another electronic control device is reset based on a change in a sensor signal related to a state of the second control object when the communication abnormality determination unit determines that the communication with the another electronic control device is abnormal.
