摘要
为了提高纯电动汽车制动时的稳定性及安全性并兼顾再生制动的效能,提出了分层架构的复合制动系统设计,建立制动驾驶意图识别模型,使电动汽车制动时,判断制动需求强度并进行制动工况划分,进而采取适宜的制动力分配策略。仿真实验结果表明:该复合控制系统在典型城市道路工况运行时满足驾驶制动需求,与无控制策略制动效果相比,制动效能及能量回收有明显的提高。
In order to improve the braking stability and safety of pure electric vehicle and take account of the regenerative braking efficiency,a layered composite braking system was proposed.Through the analysis of composite braking system working mode,this paper proposes a composite braking control strategy based on driver intention recognition to judge braking demand intensity and divide the braking condition and then to adopt appropriate braking force distribution strategy when the electric car is braking according to road sensors data fusion based on the current vehicle running state and driving intentions.The simulation results show that the composite control system can meet the driving braking requirements in typical urban road conditions,and braking efficiency and energy recovery are obviously improved compared with the braking effect without control strategy.
