Problems solved by technology

Forward Collision Warning System (FCW, Forward Collision Waring) and Automatic Braking System (AEB, Autonmous Emergenay Braking) can avoid or mitigate collisions. When the vehicle decelerates rapidly or perceives objects too late, ADAS cannot trigger FCW and AEB in time, which is easy Missing the latest braking time, resulting in an unavoidable collision

Abstract

The embodiment of the invention discloses a driving path determination method, device, equipment and a vehicle. The method comprises the steps of determining M candidate escape paths according to the initial position data of the vehicle and N target position data, determining a current driving path according to the initial driving path of the vehicle and the M candidate escape paths, and according to the position information of the object, determining collision information of the vehicle and the object on the current driving path, and if the collision information is matched with preset safety information, driving according to the current driving path, wherein M is apositive integer greater than or equal to N. On the basis of the embodiment of the invention, an end point sampling method is adopted, and the candidate escape paths are represented by adopting the 7-degree polynomial, so that each candidate escape path can be a complete path, and the precision of the candidate escape paths can be improved. Besides, the collision information of the vehicle and the object on the current driving path can be determined in real time, and the escape path can be updated in real time, so that the robustness of determining the driving path and the safety of vehicle driving can be improved.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a method, device, equipment and vehicle for determining a driving route. Background technique [0002] At present, Advanced Driving Assistance System (ADAS, Advanced Driving Assistance System) is widely used in automobiles, among which. Forward Collision Warning System (FCW, Forward Collision Waring) and Automatic Braking System (AEB, Autonmous Emergenay Braking) can avoid or mitigate collisions. When the vehicle decelerates rapidly or perceives objects too late, ADAS cannot trigger FCW and AEB in time, which is easy Missing the latest braking time, resulting in an unavoidable collision. Contents of the invention [0003] Embodiments of the present application provide a method, device, device, and vehicle for determining a driving route, which can improve the accuracy of candidate escape routes, and can improve the robustness of determining the driving route a...
