Abstract:
The driving strategy of the driver is one of the critical factors which affect the energy consumption of the vehicle. However, it is often overlooked in the researches of energy management. Moreover, there are few studies devoted to formulating specific driving strategies which consider the driving preference of the driver. This study proposes a multi-objective optimized driving strategy for dual-motor electric vehicles based on the intelligent algorithms, which mainly studies the flat road sections, the long uphill road sections, and the vehicle acceleration sections. The acceleration duration, energy consumption, and driving comfort are defined as the optimized objectives. For the economy performance, the optimized driving strategy designs the travel speed trajectory according to the given road information to guide and adjust the driving behavior, so that the vehicle can be driven economically. In the process of studying vehicle multi-objective acceleration strategy, NSGA-II, MOPSO, PESA-II and SPEA2 were adopted to solve the multi-objective optimization problem with three conflicting objectives. And the performance comparison and statistical analysis of the four algorithms were carried out. Finally, a spliced driving cycle was constructed to validate the effectiveness of the driving strategy. The results indicated that the proposed driving strategy has an excellent performance towards driving assistance. © 2021 Elsevier B.V.
