Abstract

Aiming at the application defects of traditional temperature control box in vehicle-mounted scenario, a vehicle-mounted temperature control box based on TEC was developed to control ambient temperature and diagnose hardware faults through UDS protocol. Firstly, the simulation analysis of the temperature control model is carried out, and the fuzzy temperature control algorithm based on the dynamic adjustment of the stretching factor is used to achieve a better response effect than the traditional fuzzy control. Then design temperature detection circuit, CAN communication circuit, H bridge drive circuit and ECU program. Finally, the experimental test shows that the system can communicate with the upper and lower machines through the UDS protocol, realize the temperature control and fault detection functions in the variable theory domain, and achieve the expected effect of the system.
