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: A vehicle drive assist system includes: a position detection device that detects a position of a vehicle; a map data acquisition device that acquires map data; a map matching device that determines the position of the vehicle on a road based on a detected position and the map data; an assist device that assists a driver's operation based on a determined position of the vehicle and a road shape ahead of the vehicle in a traveling direction indicated on the map data; a determination device that determines a possibility that the vehicle travels a wrong way on a road where the traveling direction is fixed to one way; and a cancel device that cancels drive assist when a possibility of reverse run exists.

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.

Abstract: In an apparatus for calibrating an inertial sensor configured to detect an angular velocity of a vehicle, an angular velocity estimator is configured to estimate a value for an angular velocity of the vehicle based on a value for an attitude of the vehicle and a value for a change in attitude of the vehicle estimated by the attitude estimator, and an error estimator is configured to estimate a value for an angular velocity error that is an error between the value for the angular velocity of the vehicle estimated by the angular velocity estimator and the value for the angular velocity of the vehicle detected by the inertial sensor. A calibrator is configured to calibrate the value for the angular velocity of the vehicle detected by the inertial sensor based on the value for the angular velocity error estimated by the error estimator.
