Liquid-cooled intercooler leakage online processing method and device and vehicle

The invention belongs to the technical field of vehicles, and discloses a liquid-cooled intercooler leakage online processing method and device and a vehicle. The online leakage processing method for the liquid-cooled intercooler comprises the steps that the actual humidity value of air in an air guide pipe of the liquid-cooled intercooler is obtained; judging whether the actual humidity value is greater than a standard preset value; if the actual humidity value is greater than the standard preset value, the liquid-cooled intercooler leaks, and the liquid inlet and the liquid outlet of the liquid-cooled intercooler are closed, so that the liquid-cooled intercooler is isolated from the cooling liquid tank, the amount of cooling liquid in the cooling liquid tank entering a gas guide pipe through leakage and then entering an engine combustion chamber is greatly reduced, and the cooling efficiency is improved. And the damage risk of the engine is reduced. The liquid-cooled intercooler and the cooling system of th
