The corresponding relation between the heat load of the whole vehicle and the heat dissipation state is preset, the current heat dissipation state can be determined based on the heat load of the whole vehicle, and different heat dissipation states are used for reflecting different heat dissipation quantity requirements.
And S102, if the heat dissipation state is the first state, starting a water cooling device of the hydrogen fuel cell engine.
The cooling device of the hydrogen fuel cell engine comprises an air cooling device and a water cooling device, wherein the air cooling device dissipates heat through a fan, and the water cooling device dissipates heat through spray cooling water.

Specifically, the heat load of the entire vehicle corresponding to the second state is greater than the heat load of the entire vehicle corresponding to the first state, that is, the heat dissipation amount required when the heat dissipation state is the second state is greater than the heat dissipation amount required when the heat dissipation state is the first state. When the heat dissipation state is the second state, the water cooling device and the air cooling device are used for dissipating heat together, so that the requirement of large heat dissipation capacity is met.
According to the heat dissipation control method, the current heat dissipation state is determined according to the current heat load of the whole vehicle, and then the heat dissipation mode adopted currently is determined, when the heat dissipation state is the first state, heat dissipation is carried out through the water cooling device, and when the heat dissipation state is the second state, heat dissipation is carried out through the water cooling device and the air cooling device together. By adopting the heat dissipation control method, the heat dissipation mode can be adjusted in real time according to the change of the heat load of the whole vehicle, the heat dissipation is avoided only by adopting a high-efficiency heat dissipation mode, excessive energy is consumed in the heat dissipation, and the condition of energy waste is caused.

Specifically, the first preset interval C1 is (a, b), the third preset interval C3 is [0, a ]. if the entire vehicle thermal load is in the third preset interval, the current heat dissipation state is the third state, the heat dissipation state is the heat dissipation requirement corresponding to the third state, and is smaller than the heat dissipation requirement corresponding to the first state.
In one embodiment, the method further comprises: and acquiring the ambient temperature, and if the ambient temperature is less than a preset temperature threshold value, starting a drain valve of a liquid collector of the water cooling device under the condition that the vehicle is not in a running state.
Specifically, after water cooling plant sprays the cooling water, the cooling water is in water cooling plant's liquid trap, and it can be 1 ℃ to predetermine the temperature threshold, if ambient temperature is less than predetermine the temperature threshold, probably leads to the cooling water refrigeration in the liquid trap, consequently, when obtaining that ambient temperature is less than predetermine the temperature threshold, opens the liquid trap drain valve to the cooling water in the discharge liquid trap, avoided the cooling water to freeze at low temperature environment, thereby lead to water cooling plant's liquid trap by the condition of frost crack.
When the vehicle is in a running state, the temperature acquisition assembly arranged on the vehicle can be used for acquiring the ambient temperature periodically, and if the acquired ambient temperature is less than a preset temperature threshold value, a drain valve of a liquid collector of the water cooling device is started when the vehicle is detected not to be in the running state, so that cooling water in the liquid collector is discharged.
