Vehicle Seat Climate Control During Ignition-Off Operation

The system dynamically adjusts the operation state of heating wire and ventilation motor based on real-time detection of user presence and environmental conditions. When a user is detected in the vehicle, the system activates seat heating/ventilation functions; when no user is present, the system deactivates these functions to save power. This dynamic adaptation resolves the contradiction between maintaining user comfort and reducing unnecessary power consumption.

The system implements feedback mechanisms by continuously monitoring vehicle ignition state, user presence detection signals, and environmental temperature conditions. Based on this feedback, the control unit intelligently determines whether to activate or deactivate seat heating and ventilation functions, ensuring energy is consumed only when actually needed for user comfort, thereby eliminating wasteful power consumption during ignition-off periods.

The existing vehicle control unit is enhanced to perform multiple functions: it continues to manage normal vehicle operations while also detecting user presence, monitoring environmental conditions, and controlling seat heating/ventilation functions during ignition-off periods. By making the control unit universal and multi-functional, the system achieves intelligent power management without adding significant hardware complexity, as the same processor handles diverse control tasks.

The control system automatically determines whether to activate seat heating or ventilation functions by itself, using built-in sensors and pre-programmed logic to detect user presence and environmental conditions. This self-service capability eliminates the need for complex additional control circuits or manual intervention, allowing the system to intelligently manage power consumption while maintaining relatively simple architecture.
