Claim 6:
7. A control method of a drive-by-wire chassis cyber-physical system under an intelligent traffic environment, based on the system according to claim 1, comprising the following steps:
1) issuing an operating signal by the driver;
2) obtaining information of the environment perception module of the drive-by-wire chassis and sensor information of the driver input module;
3) judging, by the basic control module, the driver operation according to the sensor information of the driver input module, and transmitting driver operation information and the information of the environment perception module to the supervision platform;
4) performing, by the supervision platform, real-time monitoring and diagnosis on information of the drive-by-wire chassis, and judging whether a current driver operation conforms to a current working condition; transmitting the information of the driver operation and the environment perception module obtained by the supervision platform to the big data platform in responding to availability of the current driver operation conforms to a current working condition; and, adjusting, by the supervision platform, the driver operation according to the information of the one or more computer processors to conform to the current working condition, and transmitting the information of one or more computer processors and the adjusted driver operation information to the big data platform;
5) storing, by the big data platform, the operation information transmitted by the supervision platform;
6) analyzing, by the big data platform, the driver operation information transmitted by the supervision platform; feeding back the driver operation information to the supervision platform in response to an analysis result of the driver operation information in the supervision platform as an ideal driving operation; and feeding back the ideal driving operation information obtained by data analysis to the supervision platform in response to an error between the analysis result of the driver operation information and the ideal driving operation information;
7) forming, by the supervision platform, a real-time local optimal solution for the vehicle according to the feedback information, and feeding back the local optimal solution to a drive-by-wire chassis supervised by the current supervision platform; and
8) generating, by the, an optimal traveling strategy corresponding to the local optimal solution, and transmitting the optimal traveling strategy to the steering control unit, the braking control unit and the driving control unit to control an output current of a motor in the execution module, so that a controller controls other execution mechanisms in the execution module to complete output to the vehicle.
