Abstract
To provide a driving support system that can assist in driving with high energy efficiency. [Solution] A driving support system comprising: a satellite signal receiver, an inertial sensor, and an imaging device mounted on a moving body; a storage device for storing map information; a self-position estimation unit that estimates the position, attitude, and direction of the moving body based on positioning data from the satellite signal receiver, detection data from the inertial sensor, and the map information; a road surface flatness detection unit that detects the flatness of the road surface based on the position, attitude, and direction and an image from the imaging device; and a trajectory planning unit that plans the trajectory of the moving body based on the position, attitude, direction, and flatness, wherein the inertial sensor includes a sensor that detects angular velocity around the Z axis and has a bias instability of 1.0° / h or less; and the trajectory planning unit plans the trajectory to change from a first driving line to a second driving line with a smaller inclination angle.
