Abstract: Provided is a travel road recognition device that can accurately recognize a travel road end of a travel road on which an own vehicle travels. A travel road recognition device of the present invention is a travel road recognition device that recognizes the travel road end of the travel road on which an own vehicle 301 travels, and includes: a laser radar 101 that emits a laser bean from the own vehicle 301 toward the travel road; a road surface determination unit 203 that obtains a cross slope of the travel road based on coordinate values of a point cloud obtained by the laser radar 101; and a road end determination unit 204 that obtains a change point at which a slope angle changes in the cross slope of the travel road obtained by the road surface determination unit 203, and obtains coordinate values of at least one travel road end of both sides in a cross direction of the travel road based on the coordinate values of the change point.

Abstract: The present disclosure provides a vehicle coordinating device capable of improving the accuracy of following a target path of a vehicle. A vehicle coordinating device 1 that coordinates automatic driving of a vehicle 2 by a vehicle control device 21 mounted on the vehicle 2 includes a communication unit 11, a vehicle characteristic identification unit 12, and an identification accuracy estimation unit 13. The communication unit 11 is communicably connected to the vehicle control device 21. The vehicle characteristic identification unit 12 acquires a control command value of the automatic driving and a traveling locus of the vehicle 2 from the vehicle control device 21 via the communication unit 11, and identifies the vehicle characteristic used for the automatic driving. The identification accuracy estimation unit 13 estimates the identification accuracy of the vehicle characteristic by the vehicle characteristic identification unit 12. The automatic driving coordinating unit 14 coordinates the automatic driving of the vehicle 2 based on the identification accuracy estimated by the identification accuracy estimation unit 13.
