本发明涉及车辆技术领域,尤其涉及一种整车发动机瞬态控制方法及车辆,整车发动机瞬态控制方法包括如下步骤:S1、TCU识别驾驶员对发动机存在动力需求,控制AMT的实际挡位降低至需求挡位;S2、所述发动机的烟度限制MAP切换为降挡瞬态控制烟度限制MAP’,并控制所述发动机按照所述降挡瞬态控制烟度限制MAP’中对应所述需求挡位的烟度限制值工作,所述发动机的烟度限制MAP对烟度的限制大于所述降挡瞬态控制烟度限制MAP’对烟度的限制。本发明能够提升发动机的瞬态动力输出的响应速度,从而保证整车动力,降低油耗。

    The invention relates to the technical field of vehicles, and in particular relates to a finished vehicle engine transient control method and a vehicle. The finished vehicle engine transient control method comprises the following steps: S1 a TCU identifies that a driver has a power demand on an engine, and controls the actual gear of an AMT to be reduced to a demand gear; and S2 the smoke intensity limit MAP of the engine is switched into downshift transient control smoke intensity limit MAP ', the engine is controlled to work according to the smoke intensity limit value corresponding to the required gear in the downshift transient control smoke intensity limit MAP', and the limit of the smoke intensity limit MAP of the engine on the smoke intensity is larger than the limit of the downshift transient control smoke intensity limit MAP 'on the smoke intensity. The response speed of transient power output of the engine can be increased, so that the power of the finished vehicle is guaranteed, and oil consumption is reduced.
