WIPO Patent Application WO/2021/182799
Kind Code:
A1
Abstract:
A failure detection device for a steering angle sensor according to an embodiment comprises: a steering angle sensor including a main gear that rotates together with a steering wheel, a first sub-gear and a second sub-gear that are each engaged with the main gear and have a constant gear ratio with the main gear, a first Hall IC chip for detecting the angle of the first sub-gear, and a second Hall IC chip for detecting the angle of the second sub-gear; and a control unit that determines failure of the steering angle sensor on the basis of a first angle difference between the current angle and a previous angle of the first sub-gear as detected by the first Hall IC chip, and a second angle difference between the current angle and a previous angle of the second sub-gear as detected by the second Hall IC chip.
