【摘要】：针对纯电动汽车的动力性能不足提出了基于模糊控制的纯电动汽车加速转矩控制优化策略。首先基于模糊控制对驾驶员加速意图进行识别,将加速意图分为急加速模式和一般加速模式。然后根据加速意图识别结果,在不同的加速模式下利用模糊控制对基准转矩进行不同程度的转矩补偿,提高电机转矩输出。仿真和实车实验结果表明,相比较于传统控制方法,加速转矩控制优化策略能有效地识别驾驶员的加速意图,并根据识别结果进行相应的转矩补偿以更快的响应加速意图,显著提高了纯电动汽车的动力性能。
[Abstract]:An optimization strategy for acceleration torque control of pure electric vehicles based on fuzzy control is proposed for the lack of power performance of pure electric vehicles. Firstly, the driver's acceleration intention is identified based on fuzzy control, and the acceleration intention is divided into rapid acceleration mode and general acceleration mode. Then according to the recognition result of acceleration intention fuzzy control is used to compensate the reference torque in different acceleration modes to improve the torque output of the motor. The results of simulation and actual vehicle experiments show that compared with the traditional control method, the optimization strategy of ATC can effectively identify the driver's acceleration intention, and make the corresponding torque compensation according to the recognition result to respond faster to the acceleration intention. The power performance of pure electric vehicle is improved significantly.
