Vehicle digital key positioning method and device and vehicle

The invention relates to a vehicle digital key positioning method and device and a vehicle. The vehicle digital key positioning method comprises the steps that model information of a user terminal where a digital key is located is acquired; acquiring a received signal strength indicator (RSSI) value of the digital key; determining a compensated RSSI value by using a Gaussian process regression model according to the acquired model information and the acquired RSSI value; and positioning the digital key according to the compensated RSSI value. Therefore, each digital key and each vehicle type do not need to be calibrated, so that the calibration workload is reduced; compared with a neural network, the method has the advantages that the compensated RSSI value is determined by using the Gaussian process regression model with small operand, so that the computational power is saved; compared with a linear compensation method, the accuracy of RSSI compensation is guaranteed, and the positioning accuracy of the digital key is high.
