Based on a pure electric vehicle, we have adopted a new dual motor coupling drive system to realise a smooth switch between the single motor and dual motor modes, without experiencing power interruption, and a switch between dual motor and single motor modes without experiencing power interruption and with minimum impact. Also, the structural characteristics and working mode are analysed, and the parameter matching and control strategy of the new power system are studied. Taking the 100 km power consumption as the optimisation goal, a non-dominated sequencing genetic algorithm (NSGAII) with elite strategy is adopted to optimise the coupling drive system. The results of the experiment show that the control strategy of the dual motor multimode drive system improves the vehicle economy by 12%. |
