The invention discloses a vehicle flameout prevention control method and device and a storage medium. The method comprises the steps that a gear clutch protection control signal is obtained; the engine rotating speed, the turbine rotating speed of the hydraulic torque converter and the oil temperature of the hydraulic torque converter are collected in real time; outputting an engine control strategy according to the engine speed and the target idle speed to regulate and control the engine speed or the engine torque; and/or outputting a hydraulic torque converter pressure control strategy according to the rotating speed of the engine, the target idle speed, the turbine rotating speed of the hydraulic torque converter and the oil temperature of the hydraulic torque converter so as to regulate and control the control pressure of a lockup clutch in the hydraulic torque converter. According to the technical scheme, by controlling the rotating speed and the torque of the engine and the pressure of the lockup clutch of the hydraulic torque converter in real time, the flameout problem caused by clutch protection triggering under the low-adhesion road small accelerator power upshift working condition of a vehicle can be effectively solved, and meanwhile the driving willingness of a driver can be effectively guaranteed.

    本发明公开了一种车辆防熄火控制方法、设备和存储介质。其中,该方法包括:获取挡位离合器保护控制信号;实时采集发动机转速、液力变矩器涡轮转速和液力变矩器油温;根据发动机转速和目标怠速转速输出发动机控制策略,以调控发动机转速或发动机扭矩;和/或,根据发动机转速、目标怠速转速、液力变矩器涡轮转速和液力变矩器油温输出液力变矩器压力控制策略,以调控液力变矩器中闭锁离合器的控制压力。本发明的技术方案,通过对发动机转速和发动机扭矩以及液力变矩器闭锁离合器压力的实时控制,能够有效解决车辆在低附着力路面小油门动力升挡工况下因触发离合器保护而导致的熄火问题,同时能够有效保障驾驶员的驾驶意愿。
