The invention relates to an engine idle speed control method and device, a vehicle and a computer storage medium, and belongs to the technical field of engine control. The engine idle speed control method comprises the steps that when an engine is in an idle speed working condition, the real-time temperature value of a cab is obtained; determining an engine idle speed target value based on the cab real-time temperature value and a preset cab target temperature value; and on the basis of the engine idle speed target value, the engine idle speed is controlled through a closed-loop PID control algorithm combined with feedforward control, so that the error between the cab real-time temperature value and the cab target temperature value is within a preset range. According to the method, large fluctuation of the controlled idle speed can be avoided, meanwhile, the controlled idle speed value can be reduced by setting the temperature difference, and the economical efficiency of the whole vehicle is better.
本发明涉及一种发动机怠速控制方法、装置、车辆及计算机存储介质,属于发动机控制技术领域,其中,该发动机怠速控制方法包括:当发动机处于怠速工况时,获取驾驶室实时温度值;基于所述驾驶室实时温度值与预设的驾驶室目标温度值确定发动机怠速目标值;基于所述发动机怠速目标值采用结合前馈控制的闭环PID控制算法对发动机怠速进行控制,以使所述驾驶室实时温度值与所述驾驶室目标温度值的误差在预设范围内。本发明可以避免控制的怠速转速存在较大波动,同时,温差的设定可以使控制的怠速转速值降低,整车经济性更优。
