The invention provides a vehicle ejection starting control method and device, a storage medium and a vehicle, and belongs to the technical field of vehicle control. When it is determined that a driver has an ejection starting intention, a locking mechanism of a hydraulic torque converter is controlled to be in a locking state, and a clutch is controlled to be in an opening state; after a launch starting function is activated, an engine can be controlled to operate at a target engine rotating speed, and a motor operates in a locked-rotor state; after it is detected that the brake pedal is loosened, the clutch is controlled to be closed based on the current motor rotating speed of the motor; and when it is detected that the clutch is completely closed, the engine is controlled to output according to the target engine torque. According to the embodiment of the invention, the hydraulic torque converter is kept in the locking state in the ejection starting process, and the engine operates at the target engine rotating speed, so that after the brake pedal is released, the engine can output the torque at the maximum capacity, and then the engine is matched with the motor to provide the maximum torque output for the vehicle, and the ejection starting performance of the vehicle is improved.

    本申请提供了一种车辆弹射起步控制方法、装置、存储介质和车辆,属于车辆控制技术领域,本申请实施例通过在确定驾驶员存在弹射起步意图时,控制液力变矩器的锁止机构为锁止状态,并控制离合器为打开状态,能够在弹射起步功能激活后,控制发动机运行在目标发动机转速,电机运行在堵转状态;并在检测到制动踏板松开后,基于电机的当前电机转速,控制离合器闭合;进而在检测到离合器完全闭合时,控制发动机按照目标发动机扭矩输出。本申请实施例通过在弹射起步的过程中保持液力变矩器为锁止状态,发动机运行在目标发动机转速,使得在制动踏板松开后,发动机能够以最大能力输出扭矩,进而配合电机为车辆提供最大扭矩输出,提升车辆的弹射起步性能。
