Predictive powertrain limit strategy for autonomous / autonomous vehicles

摘要

An expanded powertrain interface and strategy for an autonomous driving controller to control powertrain torque (or vehicle acceleration/deceleration) capability at the current operating point, in addition to capability for subsequent operating points at a future time based on predictive assessment of powertrain energy management, subsystem contraints/limits, and capability in the future. The powertrain interface and strategy applies to a vehicle with electrified powertrain control (hybrid electric vehicle (HEV) or pure battery electric vehicle (BEV)) with an autonomous driving (AD) capability (either full or semi-automated driving). This powertrain interface and strategy may also be used with non-electrified powertrain (conventional) systems based on available combustion engine torque at the target vehicle speed and gear.
