The invention relates to the technical field of vehicles, in particular to an electric drive assembly for a vehicle, a control method of the electric drive assembly and the vehicle, and aims to solve the problem that an existing electric drive assembly cannot reasonably monitor the temperature of a motor rotor. The electric drive assembly for the vehicle comprises a motor shaft, a motor rotor, a motor end cover and a motor shell, the motor rotor is installed on the motor shaft, the motor shaft is installed in the motor shell in a pivoted mode, the motor end cover covers the motor shell, the electric drive assembly further comprises an eddy current stator, the eddy current stator is installed on the inner side wall of the motor end cover, and the eddy current stator is installed on the inner side wall of the motor end cover. The eddy current stator is provided with a temperature sensor, and the temperature sensor is used for obtaining the temperature of the motor rotor and is in communication connection with a controller of the electric drive assembly. The temperature sensor is arranged on the eddy current stator to obtain the temperature of the motor rotor, the motor is controlled based on the obtained temperature of the motor rotor, and magnetic steel demagnetization and bearing damage caused by temperature rise of the rotor are avoided while high-speed operation of the rotor is met.
