Problems solved by technology

Conversely, if the performance of vehicle controllers and sensors is degraded, it will increase the frequency of driver's manual driving participation, reduce the driving experience, and cause danger at the same time.
[0006] (2) Automated driving decisions are limited by sensor performance
Due to the limitation of the sensing range of on-board sensors, the vehicle can only perceive the environment around the vehicle by relying on the on-board sensors, it is difficult to obtain the global information of the vehicle's driving path, and it is difficult to find potential dangerous scenes

Abstract

According to the drive-by-wire chassis vehicle intelligent driving system based on mode switching and the control method thereof disclosed by the invention, global path information, destination information and road real-time traffic state information of vehicle driving and driving state information of other vehicles around the vehicle are acquired through vehicle networking communication, so that the vehicle sensing range is greatly expanded; therefore, the driving safety and the automatic driving performance of the vehicle are improved; according to the method, switching of the vehicle among the three intelligent driving modes under different road conditions is achieved, the cloud control automatic driving mode is preferentially adopted under the dangerous road condition, the switching frequency of the manual driving mode is reduced, the driving comfort is improved, and the driving safety is improved. The cost of a vehicle sensor and a controller is reduced, and the contradiction between the performance of the vehicle sensor and the controller and the driving comfort is reduced; by adopting the vehicle autonomous driving mode under the non-dangerous road condition, the frequency that the cloud system participates in controlling the vehicle autonomous driving is reduced, the load of the cloud system is further reduced, and the utilization rate of the cloud system is improved.
