Abstract
A power steering device includes a steering mechanism structured to steer a steerable wheel in accordance with steering of a steering wheel. A first sensor is structured to sense a specific state quantity of steering. A second sensor is structured to sense the specific state quantity. A first actuation part is structured to apply a steering force to the steering mechanism. A second actuation part is structured to apply a steering force to the steering mechanism. A first microprocessor is configured to receive an output signal from the first sensor, and control driving of the first actuation part based on the output signal received from the first sensor. A second microprocessor is configured to receive an output signal from the first sensor and an output signal from the second sensor, and control driving of the second actuation part based on the output signal received from the first sensor.
