Power Management for vehicle door system
First Claim
Patent Images
1. A vehicle door system comprising:
- an actuator configured to adjust a position of a door;
a power source; and
a controller configured to control the actuator with energy provided by the power source, wherein the controller is configured to;
identify a charge level of the power source;
compare the charge level to at least one threshold; and
in response to the charge level being less than the at least one threshold, control the actuator to release the door, wherein the controller controls the actuator limiting a rate of motion of the door after the release, wherein the at least one threshold of the charge level is sufficient to supply operating energy to the actuator to complete the limiting of the rate of motion of the door after the release over the rotational path of the door to a rest position.

Abstract
A vehicle door system is disclosed. The system comprises an actuator, a power source, and a controller. The actuator is configured to adjust a position of a door. The controller is configured to control the actuator with energy provided by the power source. The controller is further configured to identify a charge level of the power source and compare the charge level to at least one threshold. In response the charge level being less than the at least one threshold, the controller is configured to output a warning signal.
