    摘要： A method for adaptive real-time optimization of a power or torque split in a vehicle having a first propulsion source (M1), a second propulsion source (M2) and a reinforcement-learning-based split controller for controlling a power or torque distribution between the first and second propulsion sources (M1, M2). The method comprises: initializing an optimal power or torque split matrix (S*) and a learning feedback variable ( λ *) of the reinforcement-learning-based split controller; obtaining a vehicle power setpoint (P SP ) or torque setpoint (TQ SP ) from a vehicle driver or a vehicle autonomous driving system; calculating a first optimal power or torque setpoint (P1 SP , T1 SP ) for the first propulsion source (M1) and a second optimal power or torque setpoint (P2 SP , T2 SP) for the second propulsion source (M2) based on a power split value derived from optimal power or torque split matrix (S*) and the vehicle power setpoint (P SP ) or torque setpoint (TQ SP ); controlling the first propulsion source (M1) using the first optimal power or torque setpoint (P1 SP , T1 SP ), and controlling the second propulsion source (M2) using the second optimal power or torque setpoint (P2 SP , T2 SP ); using a machine learning algorithm of the reinforcement-learning-based split controller for calculating a learning feedback variable ( λ ) based on measured or estimated power or torque output feedback, wherein the learning feedback variable ( λ ) represents an optimization criteria; updating the optimal power or torque split matrix (S*) when the calculated learning feedback variable ( λ ) represents an improvement in terms of the optimization criteria over the previous learning feedback variable ( λ *).
