US 2020/0047805 A1 · STEERING ANGLE DETECTION DEVICE AND ELECTRIC POWER STEERING DEVICE USING SAME

Abstract

A steering angle detection device includes plural control units and plural steering angle sensors. Each control unit is configured to transmit steering angle information related to a steering angle of a vehicle to an external device and transmit and receive information mutually therebetween. Each steering angle sensor is provided in correspondence to each control unit and configured to output a sensor signal corresponding to a detection value of a change in the steering angle to the corresponding control unit. One of the control units transmits, as a transmission control unit, the steering angle information to the external device at one transmission timing.
