Engine working condition whole vehicle economical efficiency simulation method, device and equipment and storage medium

The invention relates to an engine working condition vehicle economy simulation method, device and equipment and a storage medium, and relates to the technical field of vehicle simulation, and the method comprises the steps: obtaining the actually measured required torque, target vehicle speed and target gear of an engine based on a CAN bus; pID control is carried out according to the actually measured required torque of the engine, the target vehicle speed and the target gear to obtain simulated required torque of the engine; obtaining an engine simulation rotating speed based on the engine simulation demand torque and the target gear; and determining the vehicle economy of the engine according to the engine simulation rotating speed, the actually measured required torque of the engine and a preset engine universal characteristic table. According to the application, the actually measured required torque of the engine is taken as simulation input, and the simulation rotating speed of the engine is ensured to
