The embodiment of the invention provides a vehicle heating method and an electronic control unit. The method comprises the steps that: a water temperature, engine oil temperature and environment temperature of an engine of a vehicle are obtained when the electronic control unit is powered on; whether to heat the vehicle or not is determined according to the water temperature, engine oil temperature and environment temperature; and when that vehicle heating is conducted is determined, vehicle heating prompt information is output to a user, the vehicle heating prompt information is used for prompting the user to control the vehicle to conduct in-situ idling. Automatic and accurate judgment of vehicle heating is achieved, whether vehicle heating is conducted or not does not need to be determined manually according to experience, the accuracy of vehicle heating judgment is improved, and unnecessary vehicle heating is avoided. Therefore, waste of related resources is reduced.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a method for warming up a vehicle and an electronic control unit. Background technique [0002] For some reasons (for example, the vehicle is placed for a period of time), it is necessary to warm up the vehicle before the vehicle starts, that is, the engine needs to be idled in situ, and the engine does not perform external work at this time. After the warm-up is completed, the vehicle starts to drive. [0003] At present, when warming up the car, the driver generally determines whether the vehicle needs to be warmed up based on experience. For example, if the vehicle has been left for a period of time, the driver judges that the car needs to be warmed up before starting, and the driver performs related operations. To control the engine to idle in place, that is, to warm up the car. [0004] However, when the car is warmed up, it is necessary to m...
