摘要： Hybrid-electric powertrain control systems and methods include a set of sensors configured to measure a set of operating parameters of a set of components of the hybrid-electric powertrain that are each a constraint on minimum/maximum motor torque limits for the electric motors thereby collectively forming a set of constraints and a controller configured to perform a linear optimization to find the best engine torque values that are attainable subject to a set of constraint inequalities as defined by current vehicle state and as monitored by the set of sensors, and control the hybrid-electric powertrain based on the best engine torque values to avoid excessive torque commands that could damage physical components of the hybrid-electric powertrain and/or could cause undesirable noise/vibration/harshness (NVH) characteristics.
