Abstract

According to the powertrain and vehicle parameters of a self-developed parallel hybrid electric vehicle, the longitudinal dynamics analysis was carried out, and the simulation model was built. Using the dynamic programming global optimization algorithm, the shift schedule for a HEV automated manual transmission was studied. The results show that: through the obtained optimal economy shift schedule, the operation regions of engine and motor are optimized, the output power efficiency of powertrain is improved and the fuel consumption was nearly 12% lower than the HEV with the original shift strategy.
