Original Abstract Submitted
A steering device includes: a plurality of proximity sensors having different installation positions of electrodes on the steering wheel; and a grip determination device which determines the presence/absence of gripping of the steering wheel based on filter values Ch_R_f(n), Ch_L_f(n) of measurement values from the plurality of proximity sensors. The grip determination device includes: a capacitance threshold setter which sets a reference value Ch_0 relative to the electrostatic capacitance of the electrode; and a determiner which determines the presence/absence of gripping based on the difference between the measurement values Ch_R_d(n), Ch_L_d(n) and the reference value Ch_0. The capacitance threshold setter determines the necessity for correction of the reference value Ch_0 based on a degree of similarity in change trends of the filter values Ch_R_f(n), Ch_L_f(n) of the plurality of proximity sensors.
