电动四驱混合动力汽车扭矩分配控制

Torque Distribution Control of Electric Four-wheel Drive Hybrid Vehicle

为了更大限度地提高电动四驱混合动力车型燃油经济性及动力性的优势,该文对汽车的起步、匀速、加速及减速4种行驶工况进行了分析,对在上述工况下的能量流以相应的速度阀值进行划分,提出电动四驱混合动力车型行驶经济性关键控制参数的2种调整方案,达到了混合动力系统节能减排的目标。

In order to improve the fuel economy and power performance advantage of electric four-wheel drive hybrid vehicle, four driving conditions including starting, uniform speed, acceleration and deceleration are analyzed. Under the conditions, energy flow is divided according to the corresponding speed threshold, and two kinds of adjustment scheme of key control parameters for electric four-wheel drive hybrid＇s driving economy are put forward. The goal of energy saving and emission reduction for hybrid power system has been achieved.
