Abstract
A vehicle position attitude calculation apparatus includes: a road structure recognition portion that acquires information, calculate a road structure shape, calculate a relative road structure lateral position, and calculate a relative road structure yaw angle; a storage portion that stores the road structure shape, the relative road structure lateral position, and the relative road structure yaw angle, an autonomous navigation portion that calculates a relative trajectory; a virtual road structure recognition portion that calculates a virtual relative road structure lateral position and a virtual relative road structure yaw angle; and an output switching portion that outputs the relative road structure lateral position and the relative road structure yaw angle, while the road structure recognition portion can recognize the road structure, and output the virtual relative road structure lateral position and the virtual relative road structure yaw angle, while the road structure recognition portion cannot recognize the road structure.
