The embodiment of the invention provides a gas intake heating control method, device and system. According to the gas intake heating control method, the temperature parameters and the attribute parameters are acquired through an ECU, and then the target gas intake heating quantity and heating time needed by ignition are determined out based on the temperature parameters and the attribute parameters. A gas intake heater is controlled to work according to the target gas intake heating quantity and the heating time. The temperature parameters comprise at least one of the environment temperature,the gas intake temperature, the water temperature and the oil temperature. The attribute parameters at least comprise one or more parameters in a heater material, the lowest gas intake temperature needed during engine ignition, the minimum heating gas intake quantity needed during ignition and gas intake and leakage losses corresponding to low temperature. Thus, by means of the gas intake heatingcontrol method, the gas intake quantity and the heating time can be adjusted according to the temperature parameters, and then the efficiency of vehicle cold starting can be improved.
Description
technical field [0001] The invention relates to the technical field of heating control, in particular to an intake heating control method, device and system. Background technique [0002] The inventor found that the power of the current air intake heater is a fixed value, so that when the intake air is heated, the heat of the intake air is also a fixed value, and the method is relatively simple. Moreover, based on the current air intake heater, when the vehicle is started at low temperature, there will be phenomena such as slow start or failure to start. [0003] Therefore, how to provide an air intake heater, an intake air heating control method, device and system, which can improve the efficiency of vehicle cold start, is a major technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, an embodiment of the present invention provides an air intake heater, an intake air heating control method, device and syst...
