The invention discloses an engine control method, device and equipment of a hybrid vehicle, a storage medium and a product, and relates to the technical field of vehicle control, and the engine control method of the hybrid vehicle comprises the steps that the roughness of a road surface and the vehicle speed of the vehicle are obtained; determining the road noise of the vehicle based on the roughness and the vehicle speed; determining the maximum rotating speed of an engine of the vehicle according to the road noise; a preset efficient working rotating speed interval of an engine of the vehicle is determined; and engine control is conducted based on the engine maximum rotating speed and the preset efficient working rotating speed interval. The operation of the engine is limited according to the vehicle speed and the road surface roughness, and the noise of the engine is covered by the road noise, so that the noise generated by the engine during working is not obvious, and the non-inductive intervention of the engine is realized. Meanwhile, according to the scheme, other hardware does not need to be added, and the production and maintenance cost of the vehicle is saved.

    本申请公开了一种混动车辆的发动机控制方法、装置、设备、存储介质及产品,涉及车辆控制技术领域,所述混动车辆的发动机控制方法,包括:获取路面的粗糙度和车辆的车速;基于粗糙度和车速确定出车辆的路噪;根据路噪确定出车辆的发动机最大转速;确定出车辆的发动机的预设高效工作转速区间;基于发动机最大转速和预设高效工作转速区间进行发动机控制。由于是根据车速和路面粗糙度来限制发动机的运行,通过路噪掩盖发动机噪声,使得发动机工作产生的噪声不明显,进而达到发动机无感介入。同时,本申请的方案无需增加其他硬件,节约了车辆的生产和维护成本。
