The invention provides a driving mode control method and device of a plug-in hybrid vehicle and a vehicle-mounted terminal. The method comprises the steps that the road condition between the current position of a vehicle and a destination and the remaining power of the vehicle are acquired, and a speed limit value is determined according to the road condition and the remaining power; acquiring the current speed of the vehicle in real time; if the current speed of the vehicle is not smaller than the speed limit value, the vehicle is controlled to be driven by fuel oil; if the current speed of the vehicle is smaller than the speed limit value, the vehicle is controlled to be driven by a battery. Battery driving is adopted at the low speed, fuel driving is adopted at the high speed, the speed limit value is determined according to the current driving road condition and the remaining electric quantity, it can be guaranteed that fuel is not consumed at the low speed in the whole driving process, meanwhile, electric energy of a power battery can be fully utilized, the speed limit value is set more reasonably, and the purpose of saving oil consumption is truly achieved.

    本发明提供一种插电式混动车辆的驱动方式控制方法、装置及车载终端。该方法包括:获取车辆当前位置与目的地之间的路况及车辆的剩余电量,并根据路况及剩余电量确定速度限值;实时获取车辆当前的速度;若车辆当前的速度不小于速度限值,则控制车辆由燃油驱动;若车辆当前的速度小于速度限值,则控制车辆由电池驱动。本发明低速时采用电池驱动,高速时燃油驱动,速度限值根据当前的行驶路况及剩余电量确定,可以保证整个行驶过程中低速不消耗燃油,同时动力电池的电能又能得到充分利用,速度限值设置更合理,真正达到节约油耗的目的。
