Power closure panel system performance optimizer
A power optimizer system for power closure panels includes a closure panel power actuator system comprising at least a motor operatively connected to a vehicle closure panel. A controller is configured to determine an optimal electrical current draw for the power actuator system according to one or more inputs relating at least to a vehicle battery status, a vehicle ambient temperature, a vehicle grade, and a vehicle climate control system status. Methods of modeling/optimizing the appropriate electrical current draw for power closure systems operating in varying voltage, temperature, grade, and climate control system conditions relative to a vehicle, or other similar mechanisms are also described.
1. A power optimizer system for a vehicle, comprising:
a power actuator comprising at least a motor operatively connected to a vehicle closure panel; and
a controller configured to determine an optimal electrical current draw for the motor according to one or more inputs relating at least to a vehicle battery status, a vehicle-exterior ambient temperature, a vehicle grade, and a vehicle climate control system status.
2. The system of claim 1 , wherein the powered closure panel is selected from the group consisting of a liftgate, a decklid, a tonneau cover, a side-hinged door, a hood, a trunk, a moving glass panel, and a tailgate.
3. The system of claim 1 , wherein the input relating to the vehicle climate control system status comprises a determination of a heating, ventilation, and air-conditioning (HVAC) blower setting.
4. The system of claim 3 , wherein the input relating to vehicle climate control system status comprises an input indicative of the HVAC blower being set to a maximum speed or the HVAC blower being set to an off position.
5. The system of claim 1 , further including one or more on-board or remotely located sensors or controllers for providing the one or more inputs relating at least to the vehicle ambient temperature, vehicle grade, vehicle battery status, and vehicle climate control system status.
6. The system of claim 1 , wherein the vehicle battery status comprises an input indicative of a vehicle battery voltage condition.
7. The system of claim 1 , wherein the controller is further configured to determine the optimal electrical current draw for the motor according to an additional input of a vehicle passenger cabin air extraction rate.
8. The system of claim 7 , wherein the controller is further configured to receive inputs from one or more air flow sensors associated with one or more vehicle air extractors.
9. The system of claim 8 , wherein the power actuator is further configured to provide a soft close functionality to the vehicle closure panel.
10. A vehicle including the system of claim 1 .
11. A method for optimizing electrical current draw of a vehicle power closure, comprising:
providing a power actuator comprising at least a motor operatively connected to a vehicle closure panel and to a closure panel lift member;
providing a controller configured at least to determine an optimal electrical current draw for the power actuator according to one or more inputs relating at least to a vehicle battery status, a vehicle-exterior ambient temperature, a vehicle grade, and a vehicle climate control system status; and
providing the determined optimum electrical current draw to the motor.
12. The method of claim 11 , including operatively associating the power actuator with a power closure selected from the group consisting of a liftgate, a decklid, a tonneau cover, a side-hinged door, a hood, a trunk, a moving glass panel, and a tailgate.
13. The method of claim 11 , including, by the controller, determining the vehicle climate control system status according to a heating, ventilation, and air-conditioning (HVAC) blower setting.
14. The method of claim 13 , including, by the controller, determining the HVAC blower setting as one of a maximum speed or an off position.
15. The method of claim 11 , including operatively connecting the controller to a pulse width modulation module to provide the determined optimum electrical current draw to the motor.
16. The method of claim 11 , including providing one or more on-board or remotely located sensors or controllers for providing the inputs relating at least to the vehicle ambient temperature, vehicle grade, vehicle battery status, and vehicle climate control system status.
17. The method of claim 11 , including further configuring the controller to determine the optimal electrical current draw for the motor according to an additional input of a vehicle passenger cabin air extraction rate.
18. The method of claim 17 , including configuring the controller to receive inputs from one or more air flow sensors associated with one or more vehicle air extractors.
19. The method of claim 18 , further including configuring the power actuator to provide a soft close functionality to the vehicle closure panel.
