Abstract
A power optimizer system for power closure panels includes a closure panel power actuator system comprising at least a motor operatively connected to a lift-assist member and a closure panel counterbalancing member. A controller is configured at least to determine an optimal electrical current draw for the power actuator system according to one or more inputs relating at least to a vehicle ambient temperature and grade. One or more sensors are provided for providing the one or more inputs. The controller may also further be configured to receive a vehicle battery voltage condition input for calculating the optimum electrical current draw consistent with the environmental conditions to efficiently control the power actuator system motor. Methods of modeling/optimizing the appropriate electrical current draw for power closure systems operating in varying voltage, temperature and grade conditions relative to a vehicle, or other similar mechanisms are also described.
