【摘要】 制动状态下的能量回馈是提高电动汽车燃油经济性和延长行驶里程的一项重要技术,在制动状态下,车辆的动能通过电机转化成为电能存储到电池中。本文在分析比较国内外先进能量回馈制动系统控制策略的基础上,针对混合动力轿车的特点,提出了EQ7200HEV混合动力轿车的制动能量回馈系统控制策略,初步实现了能量回收制动力矩和液压制动力矩的合理分配及协调工作,采用dSPACE开发系统,建立了相关仿真模型,通过仿真分析对控制逻辑进行了优化。更多还原

【Abstract】 Energy Regeneration during braking is an important technique for electric vehicles to improve their fuel economy and extend their driving range. During deceleration, kinetic energy of the vehicle can be regenerated into the battery by the actions of motor as electrical energy. On the basis of analysis and comparison of various types regenerative braking system, This Paper put forward the control strategy of regenerative braking system on hybrid electric vehicle of EQ7200HEV. Hydraulic torque and Regenerative torque can assort with each other under this control strategy. We use dSPACE developing system and simulation models to achieve the optimized results of the control logics.更多还原
