The embodiment of the invention discloses a model training method, an ultrasonic sensor calibration method and device, a vehicle and a storage medium. The method comprises the steps that a training data set is acquired, and the training data set comprises an echo signal data set, a two-dimensional spectrogram data set corresponding to the echo signal data set and a parameter data set, the echo signal data set is obtained by performing data labeling on initial echo signals acquired at different acquisition sampling points by an ultrasonic sensor arranged on a target vehicle, and the parameter data set comprises related parameters of the target vehicle acquired at different sampling points; and iteratively training the to-be-trained model through the training data set until a training end condition is met to obtain a data augmentation model, and the data augmentation model is used for carrying out data augmentation on the echo signal data set to obtain a simulated echo signal set corresponding to the echo signal data set. By performing data augmentation on the echo signal data, the data acquisition efficiency is improved, and threshold curve calibration is accelerated.
