METHOD FOR MEASURING AUTOMOBILE HORSEPOWER AND ITS APPLICATION ON CHASSIS DYNAMOMETERS

摘要

The present invention provides a more accurate device and method for measuring automobile horsepower, specifically the internal combustion engine, ICE horsepower at the crankshaft, or the electric motor(s') horsepower, or the combined ICE and electric motor(s') horsepower. It applies to automobiles that do not incorporate, or can disengage, regenerative braking, RGB. The proposed device and method measures horsepower in real road test conditions, through the utilization of an accelerometer that performs measurements of the automobile velocity, acceleration and deceleration, whereas the method provided may be also applied to chassis dynamometers, resulting into a more accurate horsepower measurement by such dynamometers.
