Problems solved by technology

[0003] 1. After the untested throttle control system is directly installed in the automobile electronic control system, due to the quality of components, welding process, assembly process and other reasons, the system will inevitably have certain faults. If the electronic control system after production is completed If there is a short-circuit fault, it will cause damage to the power supply and other circuits of the original electric control system of the car after it is directly installed in the electric control system of the car, which will increase the difficulty of later system debugging. When the vehicle electronic control system is used to troubleshoot, additional costs will be added, which will also affect the factory consistency of the original vehicle electronic control system, and there will be certain safety hazards
[0004] 2. Due to the small operating space of the vehicle, it is not convenient to adjust the relevant circuit parameters of the throttle control system on the vehicle, and after the connection of the additional throttle control system is completed, the entire system needs to be powered on for parameter adjustment, which will affect the original vehicle. The control system works normally. Therefore, this method is not convenient for later modification and debugging, which will affect the progress of the project and prolong the production cycle accordingly.
[0005] At present, there is no special detection and debugging platform to detect and calibrate the performance and parameters of the throttle control system after production. Therefore, it is very useful to design a detection and debugging system specially applied to the throttle control system of autonomous vehicles. necessary
