Tandem hybrid power tracked vehicle energy management strategy based on predicted vehicle speed change

The invention discloses a tandem type hybrid power crawler energy management strategy based on predicted vehicle speed change. Comprising the following steps: (1) establishing a longitudinal dynamic model of the tandem hybrid crawler; (2) establishing an A-ECMS energy management strategy model for the tandem type hybrid power crawler; (3) predicting speed change values by using an LSTM (Long Short Term Memory) method, dividing the change values into a positive type and a negative type, classifying the predicted speed change values under different symbols by adopting a Kmeans method respectively, and obtaining threshold values in the speed change values; and (4) for the speed change value of which the absolute value is greater than the threshold value under the corresponding symbol, adjusting the equivalent factor of the corresponding A-ECMS, comparing the obtained comprehensive fuel consumption with the comprehensive fuel consumption obtained by the A-ECMS, and taking the power distribution condition of the A
