The invention provides a catapult starting control method, device and system, a vehicle and a storage medium, and belongs to the technical field of vehicle control, the method comprises the steps that under the condition that a catapult starting function of the vehicle is activated, the vehicle is controlled to enter an idling electric four-wheel drive mode, and the rotating speed of an engine is controlled to be increased to the target rotating speed; under the condition that the rotating speed of the engine is increased to the target rotating speed, the clutch is controlled to be closed to a sliding friction state; and under the condition that it is detected that the brake pedal is loosened, the clutch is controlled to be completely closed, so that the vehicle is switched to the direct drive mode from the idling electric four-wheel drive mode. According to the embodiment, when the ejection starting function of the vehicle is activated, the rotating speed of the engine is controlled to rise to the target rotating speed, the clutch is controlled to be closed to the sliding friction state, when it is detected that the brake pedal is loosened, the clutch can be rapidly controlled to be completely closed, and therefore the engine can rapidly output torque; the vehicle can enter a direct drive mode at a lower vehicle speed, and the hundred-kilometer acceleration performance of the vehicle is effectively improved.

    本申请提供了一种弹射起步控制方法、装置、系统、车辆和存储介质,属于车辆控制技术领域,方法包括:在车辆的弹射起步功能激活的情况下,控制车辆进入怠速电四驱模式,并控制发动机的转速升高至目标转速;在发动机的转速升高至目标转速的情况下,控制离合器闭合至滑磨状态;在检测到制动踏板松开的情况下,控制离合器完全闭合,以使车辆从怠速电四驱模式切换至直驱模式。本申请实施例通过在车辆的弹射起步功能激活时,控制发动机的转速升高至目标转速并控制离合器闭合至滑磨状态,能够在检测到制动踏板松开时,快速控制离合器完全闭合,以使发动机能够快速输出扭矩,让车辆能够在更低的车速进入直驱模式,有效提升车辆的百公里加速性能。
