The present invention provides a calculation method, system, storage medium and equipment for engine fuel consumption demand. The calculation method includes: obtaining the current water temperature in the cooling water tank in real time, and judging whether the current water temperature in the cooling water tank is greater than a preset water temperature threshold; When the current water temperature in the cooling water tank is greater than the preset water temperature threshold, the cooling fan group is turned on, and the target output power of the cooling fan group is obtained; calculated according to the target output power of the cooling fan group and the engine power demand The real-time fuel consumption calculated by the present invention can more accurately reflect the working state of the engine and the real fuel consumption.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a calculation method, system, storage medium and equipment for engine fuel consumption requirements. Background technique [0002] In the process of calculating engine fuel consumption, it is usually necessary to consider the impact of the cooling fan group on engine fuel consumption. In the prior art, the assessment of the impact of the cooling fan group on engine fuel consumption is mainly to consider The fuel consumption is obtained by multiplying the power of the fully-on state of the group by the empirical proportion coefficient. In actual working conditions, some cooling fans in the cooling fan group are on and some are off. The switching status of each cooling fan needs to be determined according to the Therefore, the real-time output power is different. If the cooling fan is controlled by the gear, the working power corresponding to the different gear of the cooling fan is also...
