| Abstract(E) | A broadly applicable procedure for measuring fuel economy of heavy-duty Hybrid Electric Vehicles (HEVs) is lacking. The classical approach of fuel economy testing is to follow a velocitytime sequence (drive cycle) with the vehicle on a dynamo test bench. However, these velocity-time sequences do not reveal hybrid drive train performance under different operating conditions. In this paper, a distance-based method is suggested to test heavy-duty HEV fuel economy. It is hereby standard practice that heavy-duty vehicles tend to use full throttle during acceleration, regardless their current power-to-weight ratio. Using this method, the sequence/cycle is evaluated for different vehicle masses, and for both optimal decelerations, which maximizes the recoverable energy, as well as legal maximum deceleration rates, which minimizes the route drive time. Simulations reveal that these operating conditions have large influence on the hybrid system performance; fuel economy improvement of heavy-duty HEV, compared to conventional heavy-duty vehicles, under different operating conditions could vary as much as 1 to 40 %. |
