【摘要】：針對純電動(dòng)汽車的動(dòng)力性能不足提出了基于模糊控制的純電動(dòng)汽車加速轉(zhuǎn)矩控制優(yōu)化策略。首先基于模糊控制對駕駛員加速意圖進(jìn)行識別,將加速意圖分為急加速模式和一般加速模式。然后根據(jù)加速意圖識別結(jié)果,在不同的加速模式下利用模糊控制對基準(zhǔn)轉(zhuǎn)矩進(jìn)行不同程度的轉(zhuǎn)矩補(bǔ)償,提高電機(jī)轉(zhuǎn)矩輸出。仿真和實(shí)車實(shí)驗(yàn)結(jié)果表明,相比較于傳統(tǒng)控制方法,加速轉(zhuǎn)矩控制優(yōu)化策略能有效地識別駕駛員的加速意圖,并根據(jù)識別結(jié)果進(jìn)行相應(yīng)的轉(zhuǎn)矩補(bǔ)償以更快的響應(yīng)加速意圖,顯著提高了純電動(dòng)汽車的動(dòng)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.
