The invention provides a vehicle variable working condition strategy generation method and device and a vehicle, and relates to the technical field of vehicle control, and the vehicle variable working condition strategy generation method comprises the steps that actual working condition data and target working condition data are obtained, and the working condition data comprise torque and rotating speed; a path space image is acquired, and the path space image is generated based on the vehicle performance image; a preset path planning algorithm is adopted, path optimization is carried out on the basis of the path space image, and the optimal path of the vehicle changing from the actual working condition data to the target working condition data is determined; and generating a vehicle variable working condition strategy based on the optimal path. The calibration cost can be reduced, and the vehicle variable working condition strategy generation efficiency can be improved.

    本发明提供了一种车辆变工况策略生成方法、装置及车辆,涉及车辆控制技术领域,所述车辆变工况策略生成方法包括:获取实际工况数据与目标工况数据,其中,工况数据包括扭矩和转速;获取路径空间图像,其中,路径空间图像基于车辆性能图像生成;采用预设的路径规划算法,在路径空间图像的基础上进行路径寻优,确定车辆从实际工况数据变动至目标工况数据的最优路径;基于最优路径生成车辆变工况策略。本发明能降低标定成本,提高车辆变工况策略生成效率。
