Under the L3 level automatic driving condition, the driver is in the state of leaving the driving link. Real time detection of the driver's non-driving task is an important mechanism to ensure the safe operation of the L3 level automatic driving system for the automatic driving system to understand the driver's state and evaluate the driver's emergency ability according to the driver's state. For the detection and evaluation of drivers' non-driving tasks, this study built L3 level automatic driving conditions in the real vehicle cockpit driving simulator, carried out real non-driving task collection tests on 40 subjects, carried out 10 kinds of real non-driving tasks experiments such as mobile device operation and turning around to pick up items, and constructed the corresponding real operation data set. By integrating wavelet transform convolution into MobileViT architecture, combined with backbone network optimization, embedding position adjustment and convolution kernel parameter reconstruction, the MobileViT-WT model is established by integrating multi-scale processing and enhanced local global attention mechanism. The test results show that the model achieves 93.85% classification accuracy for non-driving tasks on the self-built data set, and the accuracy of the generalized test set is 82.90%, which is 5.15% higher than the original model, and the number of parameters is 11% lower than the original model. The reasoning delay of the model processing image is only 8.0 ms. The research results can provide optimization for man-machine takeover and safety early warning of L3 automatic driving.
