Problems solved by technology

[0002] The FSAC (Chinese College Student Driverless Formula Contest) racing car is unmanned on a predetermined track, which is not suitable for all road conditions. In addition, the current unmanned driving technology is not yet mature, and it is not possible to realize completely autonomous unmanned vehicles under many working conditions. Therefore, it is very necessary to switch between unmanned and manned driving states. The traditional switching solution is to install a steering actuator clutch, which will inevitably make the steering system more complicated and the design and processing costs will be high.

Abstract

The invention relates to a general steering system and control method for driverless formula racing cars, including a power device, a steering angle monitoring device connected with the front wheels of the racing car for monitoring the steering angle, and a steering wheel angle connected with the steering wheel for monitoring the steering wheel angle A monitoring device, wherein the steering angle monitoring device is connected to the steering wheel angle monitoring device through the second steering transmission rod, the power device is connected to the steering angle monitoring device, and the power device provides power for the entire steering system; the invention can realize precise control of the automatic steering of the racing car , and does not need to install a gear separation device to eliminate the huge steering resistance of the steering gear, it can realize the switching between manned driving and unmanned driving. The structure is simple, which reduces the design and processing cost of unmanned formula racing cars, and has certain versatility.
