The invention provides a control method and system for an engine of a vehicle, a storage medium and the vehicle, and the control method comprises the steps that S1, the gas path torque of the engine is obtained; s2, calculating a torque difference between the gas path torque before filtering and the gas path torque after filtering; s3, determining a gas path torque change value according to the torque difference and a transmission gear; s4, determining a gas path torque request value according to the gas path torque change value and the gas path torque; and S5, the engine is adjusted according to the gas path torque request value. Therefore, in the working process of the engine, the gas path torque is properly adjusted, the fire path torque of the engine is prevented from being lower than the fire path minimum torque, it is ensured that the engine can respond stably, the torque response of the engine is more accurate, the response precision of the engine under the sliding working condition or interference of a transmission controller or interference of a vehicle body stabilizing system is improved, and the service life of the engine is prolonged. And the working stability of the engine is improved.
本申请提出了一种车辆的发动机的控制方法、控制系统、存储介质以及车辆以及车辆,所述控制方法,包括:S1:获取发动机的气路扭矩;S2:计算滤波前的气路扭矩与滤波后的气路扭矩的扭矩差;S3:根据所述扭矩差以及变速器档位确定所述气路扭矩变更值;S4:根据所述气路扭矩变更值以及气路扭矩确定气路扭矩请求值;S5:根据所述气路扭矩请求值调整所述发动机。由此,在发动机的工作过程中,通过调整适当调整气路扭矩,避免发动机的火路扭矩低于火路最小扭矩,以确保发动机可以稳定响应,使发动机的扭矩响应更加准确,提高滑行工况、变速器控制器干涉或车身稳定系统干涉时发动机的响应精度,以提高发动机的工作稳定性。
