DEAD RECKONING NAVIGATION DEVICE FOR VEHICLE, DEAD RECKONING NAVIGATION METHOD FOR VEHICLE AND PROGRAM FOR DEAD RECKONING NAVIGATION METHOD FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a dead reckoning navigation device for a vehicle capable of improving accuracy of calculating velocity and a yaw rate of a vehicle.;SOLUTION: The present invention comprises: a velocity vector calculation means to calculate velocity vector of a traveling velocity of a vehicle from GPS information; a tire rotation information detection means to detect rotation information of a tire; a tire rotation velocity calculation means to calculate rotation velocity of the tire from the rotation information of the tire; a velocity calculation means to calculate velocity of the vehicle based on the information on the velocity vector; a yaw rate calculation means to calculate a yaw rate of the vehicle based on the information on the velocity vector; a first parameter calculation means to sequentially calculate a first parameter for a first relational expression between the velocity of the vehicle calculated by the velocity calculation means and the rotation velocity of the tire; and a second parameter calculation means to sequentially calculate a second parameter for a second relational expression between the yaw rate calculated by the yaw rate calculation means and the rotation velocity of the tire.;COPYRIGHT: (C)2012,JPO&INPIT
