Abstract

The disclosure provides a seat heating control system and method that heat the seats by introducing high-pressure gas compressed by the compressor of the air conditioning system into the heat exchanger through an electronic throttle valve that coupled the air conditioning system and the seat heating control system. The high-pressure gas exchanges heat in the heat exchanger to raise the temperature and heat the seat, then flows out of the heat exchanger and re-enters the compressor to achieve circulation of the gas within the air conditioning system. This enables heating when the seat surface temperature is low without additional heating consumption, improving the vehicle's economy, power performance, and environmental friendliness.

Dependent claims

A seat heating control system, the vehicle comprising an air conditioning system, the air conditioning system comprising a compressor with an outlet, the compressor being configured to compress low-pressure gas into high-pressure gas for output through the outlet, the seat heating control system is in communication with the compressor, the seat heating control system comprises:

a temperature sensor configured to sense the surface temperature of the seat;
a heat exchanger disposed on the seat;
an electronic throttle valve located between the outlet and the heat exchanger and configured to communicate with or isolate the compressor from the heat exchanger. When the compressor is connected to the heat exchanger, high-pressure gas flows into the heat exchanger for heat exchange, generating heat to heat the seat;
and
a controller configured to determine whether the surface temperature is below a predetermined heating temperature;
and control the electronic throttle valve to open when the surface temperature is determined to be below the predetermined heating temperature, and configured to control the electronic throttle valve to close when the surface temperature is determined to reach a predetermined cutoff temperature.
