中文摘要:基于电动伺服系统对制动能量回收控制策略进行研究。首先对电动伺服制动系统的部件组成和工作机理进行分析;然后取车速和制动强度双参数对制动模式进行划分,并兼顾整车经济性和车辆安全性对电液制动力进行协调分配,使用制动强度、初始车速、电池SOC对电动机制动扭矩进行修正;分析了轮缸压力控制理论,并给出压力控制需求,基于电动伺服系统提出前馈加三闭环反馈的轮缸压力控制算法,实现轮缸压力的精确控制,通过仿真跟随正弦曲线目标压力对提出的算法进行验证,结果表明此压力控制算法可以满足控制需求;最后在纯电动整车平台上对提出的制动力分配策略和压力控制算法进行验证,并以制动能量回收率为节能评价指标,对制动能量回收策略进行经济性评价,试验结果验证了提出的制动力分配策略和压力控制算法的有效性和可行性。该制动能量回收策略能显著提高制动能量回收率,改善整车经济性。

Abstract:With the development of new-energy vehicles, braking energy recovery as an important means to save energy and protect environment of the new-energy vehicles causes attention widely. The control strategy of braking energy recovery based on electric servo system was studied. Firstly, the operational principle and key components of the electric servo system were analyzed and the braking modes were divided based on the vehicle speed and braking intensity. Secondly, the distribution strategy of braking force considering the economy and security of the vehicle was researched. The motor braking force was corrected by using the intensity of the brake, vehicle speed and SOC. The control theory of pressure was analyzed and control requirements were provided. The pressure-control strategy was studied based on the feedforward and feedback, aiming to control the pressure precisely and validate the control results of pressure by using Matlab/Simulink and AMESim co-simulation. Finally, the control strategy of the braking energy recovery was validated by the real-vehicle test and the economy of the vehicle was evaluated by using the rate of braking energy recovery. The rate of braking energy recovery of NEDC cycle can reach 71.38%. The results showed that the distribution strategy of braking force and the pressure control algorithm were valid and feasible and the control strategy of braking energy recovery can increase the rate of braking energy recovery and raise the economy of the vehicle significantly. Therefore, the control strategy of braking energy recovery based on electric servo system was valid and feasible. The control strategy presented can provide a useful reference for the design of braking energy recovery system for electric vehicles.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
