  • Vehicle parasitic loss and drive line efficiency test fixture and method
    Patent number: 7530263
    Abstract: A testing apparatus that is used for measuring a vehicle's parasitic loss and overall, loaded efficiency utilizes an external electric drive motor, as an input, connected to the engine crankshaft of the vehicle and dynamometers connected to each driving wheel hub, to measure output at the wheels. Although its wheels with tires are removed, the vehicle remains largely intact and rests upon vehicle supports, which are mounted to a track system under the vehicle. The track system permits the drive motor and dynamometers to adjust and accommodate any vehicle for efficiency analysis. A computer monitors the driving motor input and output at the dynamometers to calculate efficiency.
