The invention provides a control mode switching method and device, a vehicle and a storage medium, the method is applied to the technical field of vehicles, and the method comprises the steps that in the process that the vehicle is switched from a pure electric four-wheel drive mode to a direct drive mode, if a target gear is an odd gear, whether the odd gear is available or not is judged; when it is determined that the odd gears are unavailable, whether the vehicle meets the preset condition of switching to the series connection mode or not is judged; and under the condition that it is determined that the vehicle meets the preset condition, an engine of the vehicle is controlled to be in a running state, and a second clutch is controlled to be closed, so that the vehicle is switched to a series connection mode from a pure electric four-wheel drive mode. The method can ensure the power performance of the vehicle, improve the driving safety of the vehicle, and avoid the safety problem caused by stall of the vehicle due to power shortage of a high-voltage battery since the engine is frequently started and the engine is forbidden to start after the engine is frequently started.
本申请提供了一种控制模式切换的方法、装置、车辆和存储介质,该方法应用于车辆技术领域,该方法包括:在车辆从纯电四驱模式切换至直驱模式的过程中,若目标挡位为奇数挡,则判断奇数挡是否可用;在确定奇数挡不可用的情况下,判断车辆是否满足切换至串联模式的预设条件;在确定车辆满足预设条件的情况下,控制车辆的发动机处于运行状态,并控制第二离合器闭合,以使车辆从纯电四驱模式切换至串联模式。该方法能够保证车辆动力性能,提高车辆驾驶安全性,避免车辆频繁启动发动机,以及频繁启动发动机后禁止发动机启动,进而导致高压电池亏电使车辆出现失速情况引发的安全问题。
