The invention discloses a vehicle control method and a vehicle control system, and the method comprises the steps: obtaining a pre-driving route of a vehicle, the pre-driving route being divided into k road segments, k being an integer greater than 1; the target SOC of the k road sections is determined, the target SOC of the i-th road section is related to road condition information of road sections before and/or after the i-th road section, and i = 2, 3, 4,..., k-1; and when the vehicle runs on the pre-running route, at least one of an engine and a motor of the vehicle is controlled according to the actual SOC of the power battery of the vehicle and the target SOC of the road section where the vehicle is located. Therefore, according to the method, the road sections are divided for the pre-driving route of the vehicle, and the target SOC corresponding to each road section is determined, so that the vehicle works according to the target SOC of each road section when driving on each road section, and the vehicle can pass on the pre-driving route with lower energy consumption.

    本申请公开了一种车辆控制方法及车辆控制系统,其中,方法包括:获取车辆的预行驶路线,预行驶路线被划分为k个路段,k为大于1的整数;确定k个路段的目标SOC,其中,第i个路段的目标SOC与第i个路段之前和/或之后的路段的路况信息相关,i=2,3,4,…,k‑1;当车辆在预行驶路线行驶时,根据车辆动力电池的实际SOC和车辆所在路段的目标SOC,对车辆的发动机和电机中的至少一个进行控制。由此,该方法通过对车辆的预行驶路线划分路段,确定各个路段对应的目标SOC,使得车辆在各个路段行驶时根据路段的目标SOC工作,可实现车辆以更低的能耗在预行驶路线上通行。
