The invention discloses a vehicle ejection starting control method and device, a storage medium and a vehicle. The method comprises the following steps: in response to an ejection starting signal of a vehicle, acquiring a turbocharging rotating speed lower limit value of an engine of the vehicle; determining an input rotational speed upper limit value of a transmission of the vehicle and an input rotational speed lower limit value of the transmission of the vehicle based on the turbocharged rotational speed lower limit value; determining an input torque threshold value of a gearbox of the vehicle based on the input rotation speed upper limit value and the input rotation speed lower limit value; the original input demand torque of the gearbox is adjusted based on the input torque threshold value, and the target input demand torque of the gearbox is obtained; and based on the target input demand torque, catapult starting of the vehicle is controlled. The technical problem that large enough generated power is needed due to the fact that a catapult starting motor for controlling the vehicle needs to reserve large torque is solved.

    本发明公开了一种车辆的弹射起步控制方法、装置、存储介质和车辆。该方法包括:响应于车辆的弹射起步信号,获取车辆的发动机的涡轮增压转速下限值;基于涡轮增压转速下限值,确定车辆的变速器的输入转速上限值和车辆的变速器的输入转速下限值;基于输入转速上限值和输入转速下限值,确定车辆的变速箱的输入扭矩阈值;基于输入扭矩阈值调整变速箱的原始输入需求扭矩,得到变速箱的目标输入需求扭矩;基于目标输入需求扭矩,控制车辆的弹射起步。本发明解决了由于控制车辆的弹射起步电机需要储备大的扭矩而导致的需要足够大的发电功率的技术问题。
