Resistance heater control method, device and system and vehicle

Номер: CN116378800A
Принадлежит:

The invention discloses a resistance heater control method, device and system and a vehicle, and relates to the field of vehicle control. The method comprises the steps that the first working state of a vehicle engine and the first environment temperature of the environment where a vehicle is located are obtained; based on the first working state and the first environment temperature, whether a ventilation pipe of the engine is heated or not is judged; and in response to heating of the ventilation pipe of the engine, a resistance heater is controlled to start working, and the resistance heater is located at the joint of the ventilation pipe and an air inlet pipe of the engine. According to the invention, the technical problem of abnormal operation of the engine caused by ice blockage of the pipeline in the prior art is solved.
