Vehicle collision identification method, optimization method, equipment and storage medium

The invention discloses a vehicle collision recognition method and device and a storage medium, and relates to the technical field of computers, the method comprises the steps that multiple sub-signals of a vehicle in a preset time period are acquired, and the multiple sub-signals are used for reflecting the running state of the vehicle in the preset time period; processing each sub-signal by using a long short-term memory network to obtain a processed sub-signal vector; according to a preset rule, splicing the processed sub-signal vectors to obtain a signal fusion vector for collision identification; inputting the signal fusion vector into a classifier network to obtain a collision result; wherein the long and short-term memory network and the classifier network are obtained through training of historical features and historical labels, the historical features are obtained through a plurality of sample sub-signals of a historical time period, and the historical labels are obtained through historical collisio
