The embodiment of the invention provides an engine working condition determination method, a vehicle control unit and a vehicle, which can determine the global optimal working condition of an engine from multiple dimensions such as economy, NVH (Noise Vibration and Harshness) and operating environment in the vehicle driving process, so that the engine can work based on the global optimal working condition; therefore, the driving requirements of the vehicle in different driving states are met. The method for determining the working conditions of the engine comprises the steps that the first engine operation working condition of the vehicle is determined, and the first engine operation working condition is related to the real-time required power of a driver and the real-time vehicle speed; real-time operation environment parameters of the vehicle are obtained, wherein the real-time operation environment parameters comprise the remaining electric quantity, the gradient and the altitude; determining a corresponding second engine operation condition according to the real-time operation environment parameters; and determining an optimal engine operation condition according to the first engine operation condition and the second engine operation condition.

    本申请实施例提供了一种发动机工况的确定方法、整车控制器及车辆,能够在车辆行驶过程从经济性、NVH以及运行环境等多个维度确定出发动机的全局最优工况,使得发动机可以基于全局最优工况来工作,从而满足车辆在不同行驶状态下的行驶需求。其中,发动机工况的确定方法包括:确定车辆的第一发动机运行工况,其中,第一发动机运行工况与驾驶员实时需求功率以及实时车速相关;获取车辆的实时运行环境参数,实时运行环境参数包括剩余电量、坡度以及海拔;根据实时运行环境参数确定出对应的第二发动机运行工况;根据第一发动机运行工况与第二发动机运行工况确定出最优发动机运行工况。
