An energy allocation method based on off-road condition prediction

Abstract

The invention relates to an energy distribution method based on off-road condition prediction, belonging to the technical field of electric transmission, which solves the problem of energy managementof hybrid tracked vehicles in the prior art. The invention relates to an energy distribution method based on off-road condition prediction, comprising the following steps: according to vehicle historical driving information, establishing an off-road environment condition identification model of tracked vehicle based on SVM; Detecting current vehicle driving information in real time, inputting themodel, and predicting current vehicle driving condition; Predicting the vehicle speed and acceleration at the next time, and calculating the vehicle power demand at the next time according to the predicted current vehicle driving condition and the predicted values of the vehicle speed and acceleration at the next time; Based on the next time power demand, the model predictive control strategy is adopted, and utilizing the dynamic programming as an optimization algorithm to obtain the next time optimal energy distribution mode. The energy distribution of the tracked vehicle under complex off-road conditions is realized, and the power performance and fuel economy of the tracked vehicle are improved.
