摘要:
An object recognition device detects a position of a vehicle based on a running path obtained by GPS, vehicle speed, steering angle, etc., and also detects the position of the vehicle based on a result of recognition of an object obtained using a captured image of a camera. The device computes a positioning accuracy in detecting the vehicle position, which accuracy mostly deteriorates as a movement distance of the vehicle increases. Positional data of the object on the road to be recognized is stored in a map database beforehand. A recognition range of the road of the object to be recognized is set based on the detected position of the vehicle, a position of the object stored in the map database, and the computed positioning accuracy. The object is recognized for the set recognition range by processing of the captured image of the camera.

An industrial vehicle 1 includes a brake 5 that applies a driving force or a braking force to a vehicle body 22, a lift pressure sensor 632 that detects pitching vibration of a vehicle body, and a pitching control unit 62 that calculates a pitching control torque for suppressing pitching vibration and generates a pitching control signal for causing the brake 5 to output the pitching control torque. When the industrial vehicle 1 runs under a load, the pitching control unit 62 calculates the pitching control torque based on an output value from the lift pressure sensor 632 to output the pitching control signal. The brake 5 is then driven based on the pitching control signal.

A navigation system 16 acquired information relating to a point, such as a sag 520 where a decrease in vehicle speed is induced in front of a system-mounted vehicle 100. When the system-mounted vehicle 100 has reached a predetermined distance from the sag 520 concerning the information acquired by the navigation system 16 or when a predetermined time has come before reaching the sag 520, an ECU 20 and an ACC 30 controls the traveling of the system-mounted vehicle 100 such that the inter-vehicle distance from an ordinary vehicle 200 behind the system-mounted vehicle 100 increases. Therefore, even when a vehicle control device 10a is not mounted in an ordinary vehicle 200x behind the system-mounted vehicle 100, it becomes possible to prevent a decrease in the speed of the ordinary vehicle 200x behind the system-mounted vehicle 100, thereby more effectively suppressing congestion.

An accuracy level is calculated when measuring a position of a vehicle according to map matching execution history information and map database update history information. According to the calculated accuracy level, an accuracy level is identified from a plurality of stepwise levels when performing measurement by referencing a predetermined map. A control level of support control executed according to the position of the vehicle is modified according to the identified accuracy level.
