Steering device

Abstract

A steering device (1) includes: a steering angle sensor (31); a grip sensor unit (8) which measures electrostatic capacitances of a plurality of electrodes (40) to (70) provided to the steering wheel (2), and acquires the presence/absence of gripping of the steering wheel (2) by the driver and the gripping position based on these measurement results of electrostatic capacitances; and an abnormality determination device (9) which determines presence/absence of abnormality in the grip sensor unit (8). The abnormality determination device (9) determines presence/absence of abnormality in the grip sensor unit (8), based on a straight grip position while going straight prior to a steering angle detection value exceeding a predetermined left-turn steering angle threshold (or right-turn steering angle threshold); and a left-turn grip position (or right-turn grip position) while turning after the steering angle detection value exceeded the left-turn steering angle threshold (or right-turn steering angle threshold).
