The invention relates to a parameter determination method, an overheating protection method, a parameter determination device, an overheating protection device, computing equipment and a vehicle. The parameter determination method comprises the steps that on the basis of a first current value and first duration time of an electric device, actual heat of the electric device in the process of reaching a first temperature is obtained, and the actual heat is used as a heat threshold value for activating an overheat protection function; based on the second current value of the electric device and the second duration time, the second heat production amount of the electric device in the process of reaching the second temperature is obtained, and the second heat production amount is used as a heat threshold value for deactivating the overheating protection function; and obtaining the heat dissipation speed of the electric device based on the heat production amount of the electric device in the process of reaching the first temperature, the corresponding duration time and the actual heat amount. Through the method, the parameters can be simply and quickly determined so as to be applied to overheating protection.
