The invention discloses a vehicle rear wheel steering positioning method based on multi-sensor information fusion, which relates to the technical field of data encryption, and comprises the following steps: acquiring and preprocessing vehicle rear wheel data through sensors, monitoring the vehicle rear wheel data, dynamically adjusting parameter setting of the sensors according to a monitoring result, and when a vehicle generates a drift error, turning the vehicle rear wheel steering positioning method. A self-adaptive filter is used for calibration, the reading of a sensor is automatically adjusted, based on the calibrated vehicle rear wheel data, a deep learning model CNN is used for extracting a vehicle rear wheel feature vector from the calibrated vehicle rear wheel data, and based on the vehicle rear wheel feature vector, an MLP is used for constructing an information analysis fusion model. And inputting the feature vectors of the rear wheels of the vehicle into the information analysis fusion model to obtain comprehensive feature vectors, accurately positioning the positions of the rear wheels of the vehicle by using a support vector machine (SVM) based on the comprehensive feature vectors, outputting a positioning result, adjusting the steering angle of the rear wheels according to the positioning result, and feeding back the result to the control unit.
