When the door switch sensor acquires a door switch signal to be closed, the seat heating and ventilation controller judges that the door switch state is closed, and when the door is closed, whether heating or ventilation is required in a corresponding area is continuously judged.
Step S4, when the opening and closing state of the vehicle door is closed, the seat heating and ventilation controller respectively acquires an in-vehicle temperature signal and an out-vehicle temperature signal through a temperature sensor, and determines whether the seat heating requirement or the seat ventilation requirement exists according to the in-vehicle temperature signal and the out-vehicle temperature signal; it will be appreciated that the ECU receives the vehicle interior and exterior temperature signal and determines whether there is a seat heating or ventilation demand.
In a specific embodiment, when the acquired temperature signal in the vehicle and the acquired temperature signal outside the vehicle meet a preset seat ventilation condition, the seat heating and ventilation controller judges that a seat area has a seat ventilation requirement; when the acquired temperature signals in the vehicle and the acquired temperature signals outside the vehicle do not meet preset seat ventilation conditions, the seat heating and ventilation controller judges that the seat area does not have the seat ventilation requirements;
when the seat area does not have the seat ventilation requirement, judging whether the acquired temperature signals in the vehicle and the acquired temperature signals outside the vehicle meet preset seat heating conditions; when the preset seat heating condition is satisfied, the seat heating and ventilation controller determines that the seat area has a seat heating requirement, and when the preset seat heating condition is not satisfied, the seat heating and ventilation controller determines that the seat area does not have a seat heating requirement.
