混合動力汽車電子差速控制系統(tǒng)的研究

摘要：為了研究混合動力汽車的電子差速特性，通過分析汽車轉(zhuǎn)向軌跡，提出了一種新的電子差速控制方法。由于汽車轉(zhuǎn)向行駛時內(nèi)、外側(cè)車輪轉(zhuǎn)速與轉(zhuǎn)向角和車體速度之間為非線性關(guān)系，采用神經(jīng)網(wǎng)絡(luò)模型參考自適應(yīng)的控制方法。仿真結(jié)果證明，該電子差速系統(tǒng)魯棒性好，具有一定的可行性。

Abstract: In order to study the electronic differential control of Hybird Electric Vehicle, a novel method is introduced by analyzing the trajectory. Considering the nonlinear feature of the rotation speeds of the inner and outerwheels in relation to the vehicle speed and steering angle, it uses neural network model reference adaptive control to the differential system. The results of simulation verify the novel electronic differential has good robustness and the feasibility.
