。 Engine ignition key switch OF
In a vehicle equipped with a steering lock means capable of locking steering movement in the F state, a pulse output means outputs a pulse for each unit steering angle of the steering wheel, and the number of pulses output from the pulse output means is measured. pulse counting means for detecting the steering angle by the steering wheel, lock detecting means for detecting the locked state of the steering wheel, and pulse counting means for detecting the locked state of the steering wheel;
1. A steering angle detecting device for a vehicle, comprising: backup control means for backing up power supply to a state in which the steering angle can be detected until the steering angle is completely locked.
