The invention relates to the technical field of electric vehicles, in particular to an automobile power system, an extended-range electric automobile and a control method.The system comprises an engine and a first motor integrating driving, power generation and starting; the first clutch is arranged between the engine and the first motor; the second clutch is arranged between the first motor and the first driving shaft; the first motor achieves the starting function, the power generation function and the driving function through cooperation between the first clutch and the second clutch. Therefore, the problems of large logic control difficulty, high cost for realizing a four-wheel drive function and the like caused by the fact that a range-extended generator of a range-extended electric vehicle only provides a power generation function and the structure of a hybrid drive form is complicated in the prior art are solved.
本申请涉及电动车辆技术领域,特别涉及一种汽车动力系统、增程式电动汽车及控制方法,其中,系统包括:发动机和驱动发电启动一体的第一电机;设置于发动机和第一电机之间的第一离合器;设置于第一电机和第一驱动轴之间的第二离合器;其中,第一电机通过第一离合器和第二离合器之间的配合实现启动功能、发电功能以及驱动功能。由此,解决了相关技术中增程式电动汽车增程发电机仅提供发电功能,混合驱动形式结构复杂,导致控制逻辑难度大,实现四驱功能成本较高等问题。
