Benefits of technology

[0023] (1) This invention has strong adaptability to various vehicle models. The system has a built-in vehicle model identification module, which supports two identification methods: configuration code reading and hardware feedback detection. It can automatically determine whether a vehicle is equipped with an electric sunroof without manual configuration. It designs exclusive ventilation execution schemes for vehicles with and without sunroofs. Vehicles with sunroofs work together with the sunroof drive mechanism and the rear pressure relief valve to exhaust air, while vehicles without sunroofs only exhaust air through the rear pressure relief valve. At the same time, the two vehicle speed thresholds can be flexibly adjusted by calibration tools according to the aerodynamic characteristics of the vehicle model and the sealing performance of the vehicle body. It can adapt to all models of different levels and configurations without developing separate system hardware and strategies for a single model.
