The embodiment of the invention provides a control method and a control device for obtaining the temperature of a motor rotor and a vehicle. The control method applied to the motor controller comprises the steps that when the vehicle meets the preset estimation condition, the first stator temperature, the first rotor temperature, the first motor rotating speed and the first motor output torque ofthe motor in each control period within the first preset time before the current control period are obtained and input into a radial basis function neural network obtained through pre-training, and afirst temperature deviation is obtained; and a second rotor temperature of the current control period is obtained according to the second stator temperature of the current control period. According tothe technical scheme provided by the embodiment of the invention, by obtaining the basic parameters of the motor and obtaining the first temperature deviation between the stator and the rotor by utilizing the radial basis function RBF neural network, the rotor temperature is further obtained, and the rotor temperature can be estimated and obtained in real time and the precision of the rotor temperature can be ensured compared with the prior art when the vehicle runs.
