基于单轮台架制动能量回收控制算法的研究

电动汽车在制动情况下提供一个良好制动性能的同时保证其能进行能量回收是电动汽车能量回收控制系统的一个重要特性。针对此特性,以本实验室的单轮ABS制动台架为原型,提出了一套控制算法,不仅合理地分配了制动器制动力和电机制动力之间的关系,而且顾及到了制动时进行制动能量回收的问题,使得电动汽车在获得制动安全性的前提下有一个良好的经济适用性,这对延长电动汽车的续驶里程有着重要的实际意义。

Research of Braking Energy Recovery Control Algorithm Based on Single Wheel Bench

Electric vehicle can provide a good braking performance under braking,while energy recovery can be guaranteed is an important feature for the electric vehicle control system.We propose a control algorithm which takes single-wheel ABS brake in our laboratory as the prototype bench,which can allocate the relationship between the braking force and the electronic brake force properly,and meanwhile,the braking energy recovery is also considered when the electric vehicle is under braking.It can make the electric vehicle has a good economic fitness in the premise of getting a safety brake,which has an important practical significance to extend driving range of electric vehicles.
