包含能耗制动的功率分流HEV制动控制策略的研究

摘要

通过分析电制动过程中能耗制动系统的工作和控制过程,为功率分流混合电动车提出了一种包含能耗制动的机电联合制动控制策略,采用试验数据和数学模型相结合的方式建立了整车仿真模型,选用典型城市驱动循环工况进行了仿真.结果表明,提出的制动控制策略能保证整车制动过程中蓄电池的充电安全性,并可高效地回收制动能量.%By analyzing the working and controlling process of the energy consuming braking system, an e-lectro-mechanical braking control strategy incorporating energy consuming braking is proposed for a power-split HEV. By combining test data and mathematical formulae, a vehicle simulation model is built, on which a simulation is conducted with UDDS driving cycle. The results demonstrate that with the braking control strategy proposed, the charging safety of batteries in braking process can be ensured, and the braking energy is reclaimed efficiently.
