The invention provides a vehicle energy-saving method and device based on road condition fusion, and the method comprises the steps: obtaining the environment information of a vehicle, and the environment information comprises the current road condition information, the traffic light information and the vehicle position information; based on the traffic signal lamp information and the vehicle position information, determining a driving distance from the vehicle to a traffic signal lamp intersection; based on the driving distance, the current road condition information and the traffic signal lamp information, calculating an allowable vehicle speed range of an intersection without waiting for passing through the traffic signal lamp; determining an output efficiency interval of a motor of the vehicle based on the allowable vehicle speed range; based on the output efficiency interval, the optimal vehicle speed of the vehicle is determined; and controlling the vehicle to run at the optimal vehicle speed according to the optimal vehicle speed. Therefore, the vehicle is prevented from waiting at the intersection of the traffic signal lamp, namely the vehicle is prevented from starting after parking, and the purpose of saving the energy consumption of the vehicle is achieved.

    本申请提供一种基于路况融合的车辆节能方法及装置,该方法包括:获取车辆的环境信息,所述环境信息包括当前路况信息、交通信号灯信息及所述车辆位置信息;基于所述交通信号灯信息和所述车辆位置信息,确定所述车辆到交通信号灯路口的行驶距离;基于所述行驶距离、所述当前路况信息和所述交通信号灯信息,计算无需等待通过所述交通信号灯路口的允许车速范围;基于所述允许车速范围,确定所述车辆的电机的输出效率区间;基于所述输出效率区间,确定出所述车辆的最优车速;根据所述最优车速,控制所述车辆以所述最优车速行驶。从而可避免车辆在交通信号灯路口等待,即避免车辆停车后再起步,以达到节约车辆能耗的目的。
