The invention relates to a control method for a transmission structure of a hybrid vehicle. The control method comprises the steps that the optimal working interval of an engine is obtained; monitoring battery pack electric quantity of the vehicle; the driving mode of the transmission structure is switched according to the obtained optimal working interval and the monitored electric quantity, and when the running speed of the vehicle is in the optimal speed interval corresponding to the optimal working interval of the engine, the transmission structure enters a fuel oil direct drive mode; when the vehicle speed is lower than the optimal speed interval and the battery pack is sufficient, the transmission structure enters a pure electric mode; when the vehicle running speed is lower than the optimal speed interval and the battery pack is insufficient, the transmission structure enters a low-speed range extending mode; and when the running speed of the vehicle is higher than the optimal speed interval, the transmission structure enters a high-speed hybrid mode. The invention further provides a transmission structure of the hybrid vehicle capable of executing the control method. According to the embodiment of the invention, the engine always works or does not work in the optimal working interval, so that the fuel efficiency of the engine is improved.
本发明涉及一种混动车辆的传动结构的控制方法,包括:获取发动机的最佳工作区间;监测车辆的电池组电量;和根据获取的最佳工作区间和监测的电量,切换传动结构的驱动模式,其中,当车辆行驶速度处于与发动机的最佳工作区间相对应的最佳速度区间时,传动结构进入燃油直驱模式;当车速低于最佳速度区间且电池组电量充足时,传动结构进入纯电模式;当车辆行驶速度低于最佳速度区间且电池组电量不足时,传动结构进入低速增程模式;和当车辆行驶速度高于最佳速度区间时,传动结构进入高速混动模式。本发明还提供了一种能够执行所述控制方法的混动车辆的传动结构。通过本发明实施例,发动机始终在最佳工作区间内工作或不工作,提升了发动机的燃油效率。
