Zusammenfassung:The invention discloses an engine universal characteristic detection method and module. The detection method comprises the following steps: the front wheels of a vehicle are driven separately, the vehicle is put in the direct gear, and the resistance of the transmission system is collected; the front wheels of the vehicle are driven separately, the vehicle is put in the direct gear, the vehicle isput at full throttle, and the wheel-side force at the maximum driving force is collected; the maximum driving force is calculated according to the resistance of the transmission system and the wheelwheel-side force at the maximum driving force; the actual load is calculated according to the maximum driving force and the resistance of the transmission system; the wheel-side power is calculated according to the actual load and the vehicle speed; the fuel consumption per 100 kilometers is obtained; the instantaneous fuel consumption is calculated according to the fuel consumption per 100 kilometers and the vehicle speed
