The invention discloses a launch control method, device and equipment for a vehicle and a medium. In response to the ejection starting operation that a driver steps on an accelerator and a brake at the same time, the output torque of the engine is controlled to be increased from the initial torque to the preset maximum torque, and the first engine torque actually output by the engine in the increasing process is obtained; based on the first engine torque and the maximum bearing torque of the clutch, a first demand torque is determined, and the motor is controlled to operate according to the first demand torque; in response to brake loosening operation of the driver, the output torque of the engine is controlled based on the preset maximum torque, and the second engine torque actually output by the engine is obtained; and on the basis of the second engine torque, the maximum bearing torque of the clutch and the maximum bearing torque of the transmission, the second demand torque is determined, the motor is controlled to operate according to the second motor demand torque, the clutch is prevented from being abraded during ejection starting, meanwhile, the dynamic property of the vehicle is improved, and the use experience of a user is improved.
本发明公开了一种车辆的弹射起步控制方法、装置、设备及介质。响应于驾驶员同时踩踏油门和刹车的弹射起步操作,控制发动机的输出扭矩从初始扭矩上升为预设最大扭矩,并获取上升过程中发动机实际输出的第一发动机扭矩;基于第一发动机扭矩和离合器的最大承受扭矩,确定第一需求扭矩,并控制电机按照第一需求扭矩运行;响应于驾驶员的刹车松开操作,基于预设最大扭矩控制发动机的输出扭矩,并获取发动机实际输出的第二发动机扭矩;基于第二发动机扭矩、离合器的最大承受扭矩和变速器的最大承受扭矩,确定第二需求扭矩,并控制电机按照第二电机需求扭矩运行,实现了避免弹射起步时磨损离合器的同时提升了车辆的动力性,提升了用户的使用体验。
