前、后轴双电动机驱动纯电动客车的 转矩分配策略.

To solve the coordination problem between the driving anti-skid strategy and the optimal torque distribution strategy, based on the real-time particle swarm optimization algorithm, a comprehensive torque distribution strategy with the consideration of stability and economy of vehicles was proposed. The driving anti-skid strategy with slip rate as control target could output the front and rear axle torque constraints. By the particle swarm optimization with real-time optimization as optimization method and with front and rear axle torque constraints as dynamic constraint condition, the optimal torque distribution strategy could run normally when the anti-skid strategy took effect. Based on AVL-Cruise and Simulink platform, a joint simulation model of vehicle economy was established to analyze the optimization effect. The results show that under the three selected cycle conditions, the power consumption per hundred kilometers is averagely decreased by 4. 79%, and the driving mileage is averagely increased by 5. 49%. The comprehensive torque distribution strategy can improve the fuel economy on the premise of ensuring the longitudinal stability of bus. [ABSTRACT FROM AUTHOR]
