The invention discloses an engine start-stop control method, device and equipment and a storage medium, and the timing for starting an engine is determined according to a comparison result between a load resistance value and a load resistance value under a preset driving condition. After the engine is started, in order to avoid the situation that the started engine stops running in advance due to the fact that the started engine does not meet the control requirement, accurate recognition is conducted on the air pressure requirement of the reference air cylinder by combining the air pressure value change rate of the reference air cylinder, and whether the engine is adjusted to be running continuously or stopped in the preset running mode is determined. On the basis, the accuracy of vehicle control requirement judgment before and after the engine is started is improved, the engine starting and stopping mode suitable for the current vehicle is determined, accurate control over engine starting and stopping is achieved, and frequent starting and stopping of the engine in a short time due to the fact that the engine stops running under the condition that the control requirement is not met is avoided.
本申请公开了一种发动机启停控制方法、装置、设备及存储介质,通过负载阻力值与预设的行驶状况下的负载阻力值之间的对比结果,确定开启发动机的时机。在发动机启动后,为避免启动后的发动机由于未满足控制需求提前停止运行,结合参考气缸的气压值变化率,对参考气缸的气压需求进行准确识别,确定在预设运转方式下,对发动机的调整方式为持续运行,还是停止运行。基于此,本申请通过提升对发动机启动前、启动后,车辆控制需求判断的准确性,确定适用于当前车辆的发动机启停方式,实现对发动机启停的准确控制,避免发动机在未满足控制需求的情况下,停止运行,导致短时间内发动机的频繁启停。
