Abstract
At least some embodiments of the present disclosure are directed to systems and methods of online power management for hybrid powertrains. In some embodiments, the hybrid powertrain control system is configured to conduct a brake-thermal-efficiency (BTE) estimation procedure when the powertrain is in operation by operating the hybrid powertrain at a plurality of speeds for a plurality of designated power levels and select certain BTE operating conditions to update the power management.
Claims20
A method of online power management for a hybrid powertrain, the method comprising:
- receiving, by a controller comprising one or more processors, measurement data when the hybrid powertrain is in operation, the measurement data comprising fuel flow rate data;
- pausing, by the controller, a power management of the hybrid powertrain when the hybrid powertrain is in operation;
- operating, by the controller, the hybrid powertrain at a plurality of speeds for a plurality of designated power levels;
- determining, by the controller, a plurality of brake-thermal-efficiencies (BTEs) based on the measurement data, each BTE of the plurality of BTEs being determined for one of the plurality of designated power levels at one of the plurality of speeds when the hybrid powertrain at a steady state;
- and
- selecting, by the controller, a BTE from the plurality of BTEs for each of the plurality of designated power levels, the selected BTE corresponding to a speed.
A system of online power management for a hybrid powertrain, the system comprising:
- one or more memories having instructions;
- and
- one or more processors configured to execute the instructions to perform operations comprising:
- receiving measurement data when the hybrid powertrain is in operation, the measurement data comprising fuel flow rate data;
- pausing a power management of the hybrid powertrain when the hybrid powertrain is in operation;
- operating the hybrid powertrain at a plurality of speeds for a plurality of designated power levels;
- determining a plurality of brake-thermal-efficiencies (BTEs) based on the measurement data, each BTE of the plurality of BTEs being determined for one of the plurality of designated power levels at one of the plurality of speeds;
- and
- selecting a BTE from the plurality of BTEs with a corresponding speed for each of the plurality of designated power levels.
