Abstract:

To meet the need of automatic identification of test types, which is aimed at automatic processing of vehicle handling and stability test evaluation indicators, this paper proposes a vehicle handling and stability test type recognition method based on convolutional neural network. On the basis of analyzing the image characteristics of the test type data, a vehicle handling and stability test type recognition model based on convolution neural network is established, which consists of 1 input layer, 3 convolution layers, 3 batch normalization layers, 2 Max-pooling layers, 5 linear rectification function (ReLU) layers, 3 full connection layers, 2 Dropout layers, 1 Softmax layer and 1 classification layer. The model is trained and verified using 2 250 groups of data collected from the tests. The accuracy of type recognition is 99.33%, and the average recognition time is 0.05 s. The results show that the vehicle handling and stability test type recognition method based on convolutional neural network proposed in this paper can effectively distinguish different test types, which can be used for automatic processing of vehicle handling and stability test results, and can significantly improve the automatic processing level of vehicle handling and stability test.
