A current position detector for a vehicle includes: an angular speed sensor; a speed sensor; a GPS receiver; a traveling trajectory estimating element for estimating a relative trajectory based on an orientation change amount and a traveling distance, and for estimating a traveling trajectory based on the relative trajectory and a GPS signal; and an error estimating element for estimating and correcting each error of an angular speed signal, a speed signal and the GPS signal. The error estimating element estimates a gain error of the angular speed signal such that an attachment angle gain error attributed to an attachment angle of the angular speed sensor and an angular speed gain error attributed to a non-linear gain property of the angular speed sensor are independently estimated. |
