Abstract

The invention provides a diagnosis method and device of a heat dissipation system, a vehicle, electronic equipment and a storage medium. The method comprises the following steps: determining a vehicle operating state, and initiating a diagnostic program, collecting current environment temperature, temperature of gas passing through an intercooler and the current water temperature of an engine; and determining the water temperature of the engine under full load according to the current environment temperature, the temperature of the gas passing through the intercooler, the current water temperature of the engine, a preset ratio of the heat dissipation power of the radiator, the ratio sum of the heat dissipation power of the intercooler and the environment temperature under full load, anddetermining whether the heat dissipation system breaks down or not according to the water temperature of the engine under full load. The technical problem that in the prior art, the timeliness of a diagnosis mode is poor is solved, and meanwhile due to the fact that whether the heat dissipation system breaks down or not can be diagnosed in real time, safe operation of a vehicle is guaranteed.

Description

technical field [0001] The present application relates to the technical field of vehicle heat dissipation, and in particular to a diagnosis method, device, vehicle, electronic equipment and storage medium of a heat dissipation system. Background technique [0002] The heat dissipation system of the vehicle is an essential part to ensure the operation of the vehicle. In the existing heat dissipation system, an intercooler and a radiator are generally included. When the vehicle is running, when the radiator is blocked, the heat dissipation efficiency of the cooling system cannot be guaranteed, and the vehicle engine will overheat. In order to avoid this situation, it is necessary to detect the state of the cooling system. [0003] In the prior art, the vehicle is subjected to a bench test to diagnose whether there is a fault in the cooling system. Generally, by making the vehicle run in an extremely hot environment and under full load, the water temperature of the engine is...
