The interest in autonomous electrified vehicles has rapidly increased in recent years. In this paper, a speed trajectory generation method based on speed and road grade preview over a short horizon is presented, to improve energy efficiency of the autonomous power split HEV and BEV. The speed trajectory is generated by minimizing the required cumulative over the the horizon wheel power, including regenerative power. We confirm by simulations that the generated speed profiles improve MPG (or MPGe) even though only a short horizon preview information is used with small deviation permitted from the nominal speed profile.
