在现有的汽车领域中,对汽车的排放要求越来越高,汽车的油耗需要降到5L或更低,作为汽车中油耗较高的豪华纵置车,目前横置双电机混动机构已经在国内产生大批量推广应用效应,并且油耗很低,可以达成油耗低于5L的目标,但是目前纵置双电机混动机构应用较少。
另外,目前随着电动车的逐渐普及,消费者对于电动车的接受度越来越高,有调研机构发现购买并驾驶过电动车的消费者绝大部分再换车的时候还是会选择电动车,不再能接受传统燃油车的驾驶感受。因此,为了满足消费者电动车驾驶感受需求,同时还没有里程焦虑,需要汽车厂家开发基于电驱为主的双电机混动机构。
然而,目前的增程式电动车有一个比较大的缺点是在车辆电池电量不足的情况下,增程模式的电动车油耗很高,尤其是在高速行驶的时候。同时,增程模式下电动车的性能出现明显下降,只能实现基础行驶要求。现有的汽车的混动机构一般采用横向分布的设置,这样,空间的利用率不高,会增加汽车的宽度要求,使得汽车的结构更加的复杂。
