System, method, and apparatus for controlling power output distribution in a hybrid power train |
摘要 |
A method includes defining an application operating cycle and a number of behavior matrices for a hybrid power train that powers the application, each behavior matrix corresponding to operations of the hybrid power train operating in a parallel configuration. The method includes determining a number of behavior sequences corresponding to the behavior matrices and applied sequentially to the application operating cycle, confirming a feasibility of each of the behavior sequences, determining a fitness value corresponding to each of the feasible behavior sequences, in response to the fitness value determining whether a convergence value indicates that a successful convergence has occurred, and in response to determining that a successful convergence has occurred, determining a calibration matrix in response to the behavior matrices and fitness values. The method includes providing the calibration matrix to a hybrid power train controller. |

1. A method, comprising:
defining an application operating cycle for a vehicle, wherein the vehicle includes a hybrid power train structured to power the vehicle and a hybrid power train controller; defining a plurality of behavior matrices for the hybrid power train, wherein each behavior matrix corresponds to operations of the hybrid power train operating in a parallel configuration, the operations comprising operations of power providing components comprising a portion of the hybrid power train, wherein the power providing components comprise an internal combustion engine and at least one electrical torque provider; determining a plurality of behavior sequences, each behavior sequence corresponding to one of the behavior matrices and comprising a sequential set of values comprising the corresponding behavior matrix applied sequentially to the application operating cycle; confirming whether each of the behavior sequences is feasible; determining a fitness value corresponding to each of the behavior sequences confirmed to be feasible; in response to the fitness value corresponding to each of the confirmed feasible behavior sequences, determining whether a convergence value indicates that a successful convergence has occurred by determining whether an incremental improvement in a characteristic fitness value is lower than a convergence threshold value; in response to determining that a successful convergence has occurred, determining a calibration matrix in response to the behavior matrices and the fitness values; and controlling the hybrid power train with the hybrid power train controller in response to the calibration matrix. |
