The invention provides an engine start-stop control method and device, a storage medium and a vehicle, and belongs to the technical field of vehicle control. The method comprises the steps that the current remaining oil quantity of the vehicle and/or the current remaining capacity of a power battery are/is obtained; based on the current remaining oil quantity and/or the current remaining capacity, the target start-stop limiting frequency is determined; and forbidding the motor to start the engine under the condition that the start failure times of the motor failing to successfully start the engine reach the target start-stop limit times. According to the embodiment of the invention, the number of times of starting the engine by the motor can be reasonably limited according to the current remaining oil quantity of the vehicle and/or the current remaining capacity of the power battery, so that the vehicle can retain more electric quantity of the power battery in a low-oil-quantity or oil-free scene, and the situation that the engine is ineffectively dragged by the motor for many times is effectively avoided; and the electric quantity of the power battery is further reduced or even over-discharged.

    本申请提供了一种发动机启停控制方法、装置、存储介质和车辆,属于车辆控制技术领域,方法包括:获取车辆的当前剩余油量和/或动力电池的当前剩余容量;基于当前剩余油量和/或当前剩余容量,确定目标启停限制次数;在检测到电机未能成功启动发动机的启动失败次数达到目标启停限制次数的情况下,禁止电机启动发动机。本申请实施例能够根据车辆的当前剩余油量和/或动力电池的当前剩余容量,对电机启动发动机的次数进行合理限制,使得车辆能够在油量较低或无油场景下,保留动力电池更多的电量,进而有效避免电机多次无效拖动发动机,造成动力电池电量进一步降低甚至过放的情况发生。
