Original Abstract Submitted
A steering device includes a measurement circuit which measures electrostatic capacitance of an electrode provided to a steering wheel, and a grip determination device which determines presence/absence of gripping of the steering wheel based on a measurement value Ch_d from the measurement circuit. The grip determination device includes a capacitance threshold setter which sets a reference value Ch_0 for the electrostatic capacitance of the electrode, and a determiner which determines presence/absence of gripping of the steering wheel based on a difference between the measurement value Ch_d and reference value Ch_0. The capacitance threshold setter changes the reference value Ch_0(n) according to a change amount dCh_0(n) in the measurement value when the absolute value |a(n)| for the slope of the filter value Ch_d_f(n) of the measurement value was less than a predetermined slope threshold a_th.
