| 摘 要： | 通过分析工况和驾驶风格对制动能量回收的影响，提出了一种考虑工况和驾驶风格耦合影响的制动能量回收方法。通过驾驶员在环实验平台采集了踏板信号与车速信号；定义了制动力的工况修正因子α和驾驶风格修正因子β，并分别利用正态分布与t分布的方法确定了其变化范围，在此基础上，制定了制动能量回收策略。利用采集的工况数据和驾驶风格数据，通过学习向量量化（LVQ）神经网络训练了工况和驾驶风格识别模型。最后，建立仿真模型对制动能量回收策略进行仿真验证，结果表明：在工况和驾驶风格耦合影响下，所提出的制动能量回收策略的能量回收效率更高，整车的经济性得到进一步提高。

| Abstract: | The influences of driving cycles and driving styles on braking energy recovery were analyzed, and a method of braking energy recovery was proposed by considering the coupling effects of driving cycles and driving styles. The pedal signals and velocity signals were collected by the driver-in-loop experimental platform. The driving cycle correction factor α and driving style correction factor β of the braking forces were defined, and their ranges were determined by using normal distribution and t distribution methods respectively, and then, the braking energy recovery strategy was established. The collected data of driving cycles and driving styles were used to train the recognition models of driving cycles and driving styles through learning vector quantization neural network. Finally, a simulation model was established and the braking energy recovery strategy was verified. The results show that the energy recovery efficiency of the braking energy recovery strategy proposed herein is higher, which considers the coupling influences of driving cycles and driving styles, and the economy of the vehicles is improved. |
