Allocating method and device for electricity generating power of hybrid electric vehicle in series connection mode

The invention relates to an allocating method and device for electricity generating power of a hybrid electric vehicle in a series connection mode. The allocating method comprises the following steps of when the power source of the hybrid electric vehicle is in the series connection mode, allocating ISG electricity generating power for driving the vehicle and charging a power battery according to the order of priority of power requirements for driving the vehicle and power requirements for charging the power battery; and when braking energy is recycled, prior allocating TM electricity generating power for charging the power battery. According to the technical scheme of the allocating method and device disclosed by the invention, when the allocation of the electricity generating power to the power requirements for driving the vehicle and the power requirements for charging the power battery is considered in the series connection mode, the ISG electricity generating power is allocated to preferentially meet the requirements for driving the vehicle, so that certain vehicle power performance is guaranteed; when the braking energy is recycled, the TM electricity generating power is preferentially allocated to charge the power battery, so that better economical efficiency can also be achieved.
