电动物流车制动能量回收控制策略研究

Control Strategy of Braking Energy Recovery for Electric Logistics Vehicle

目前,续航里程问题依旧是限制电动汽车发展的重要问题之一。将某电动物流车作为研究的目标车辆,分析制动能量回收系统结构和限制因素,设计基于路面附着系数识别的制动能量回收控制策略,对电机再生制动力接入制动系统的工作点进行优化,建立Simulink控制策略,结合Cruise整车模型在中国典型城市工况和NEDC循环工况下进行联合仿真,对仿真结果进行分析验证。

At present,the range problem is still one of the important problems limiting the development of electric vehicles.Will be an electric car logistics as the research target,analysis of braking energy recovery system structure and constraints,design based on the identification of the tire-road friction coefficient of brake energy recovery control strategy,the motor regenerative braking brake system access to the set-point optimization,establishing Simulink control strategy,combined with the Cruise vehicle model under the condition and the NEDC cycle conditions in typical cities in China under the joint simulation,analyzes the results of simulation verify.
