Specifically, the signal characteristic value of the elastic wave signal acquired by the sensor may be compared with a pre-stored reference characteristic value to obtain corresponding information of the touch object. For example, converting an elastic wave signal into a corresponding voltage signal, and then obtaining a signal characteristic value of the voltage signal according to a signal waveform characteristic of the voltage signal; then, a characteristic model can be established through a machine learning algorithm and/or a deep learning algorithm according to a voltage signal converted when a preset touch object touches the vehicle; calculating to obtain a signal characteristic value of the voltage signal according to the voltage signal and the characteristic model; in this embodiment, a feature model may also be established by a support vector machine algorithm according to a voltage signal converted by a predetermined touch object touching the vehicle and a corresponding reference feature value; specifically, in actual work, a worker can collect elastic wave signals generated when different objects touch a vehicle in advance, convert the elastic wave signals into voltage signals, train the voltage signals as input signals through a machine learning algorithm and/or a deep learning algorithm to obtain a feature model for extracting signal feature values in the voltage signals, and manually analyze feature parts with higher differences in the voltage signals to obtain feature values corresponding to the voltage signals, wherein the feature values are reference feature values corresponding to the voltage signals; at the moment, the voltage signal is used as input, the reference characteristic value is used as output, and a characteristic model is established through a deep learning algorithm or a machine learning algorithm; therefore, when an actual accident occurs, the voltage signal converted from the elastic wave signal can be analyzed and calculated through the characteristic model to obtain a corresponding signal characteristic value. Certainly, in actual work, a feature model can be obtained by collecting a large number of voltage signals generated by touch and utilizing the voltage signals through a machine learning algorithm and/or a deep learning algorithm, a signal feature value of the touch can be obtained through the feature model and the voltage signals generated by actual touch of a user in a later period, and then the type information of an object can be obtained according to the signal feature value; the invention is not limited in detail, and those skilled in the art can select the application according to the actual needs.
