Abstract: A vehicle trajectory calculation method is provided. In the vehicle trajectory calculation method, a travel trajectory of a vehicle in a travel route is calculated based on a GPS signal received at predetermined time intervals with a GPS receiver of the vehicle during traveling. When there is an unmeasurable section where the travel trajectory cannot be normally calculated based on the GPS signal, the travel trajectory in the unmeasurable section is calculating by performing an interpolation based on the calculated travel trajectories in sections anterior to and posterior to the unmeasurable section.

Abstract: In this vehicle orientation detection method detecting the orientation of a vehicle on the basis of measurement data obtained at prescribed time intervals, as long as a speed sensed by a vehicle speed sensor is less than a threshold speed, the vehicle orientation is detected on the basis of a yaw rate sensed by a yaw rate sensor. If the speed detected by the vehicle speed sensor is greater than or equal to the threshold speed, a drift determination is performed. If not determined to be in a drift state, the vehicle orientation is detected on the basis of signals received by a GPS receiver, and if determined to be in a drift state, the vehicle orientation is detected on the basis of the yaw rate sensed by the yaw rate sensor.
