摘要
以ISG(integrated startor and generator)型混合动力长安轿车为原型,提出了基于HEV(hybrid electric vehicle)制动力分配的制动系统压力协调控制策略,建立了HEV再生制动离线仿真模型。研制了HEV摩擦制动液压实验系统,构建了dSPACE环境下的混合动力再生制动硬件在环仿真试验平台,进行了不同制动强度下的再生制动系统性能实验,验证了制动力分配和制动压力协调控制的正确有效性。
With a focus on a Changan hybrid electric vehicle （HEV） with an integrated startor and generator （ISG）, strategies for braking force distribution and coordinated pressure control are put forward, and a dynamic braking control model is constructed for off-line simulation. A hydraulic braking system for HEV and a regenerative braking rig are built in dSPACE environment. deceleration events are carried out, which show the strategies for braking Tests and analyses of different force distribution and coordinated pressure control for HEV are reasonable and available.
