Abstract

Powered retractable vehicle step assist systems and methods are provided. The steps systems are configured for installation (e.g., after market installation) and use with a vehicle. The system can include a stepping member movable between a retracted position and a deployed position with respect to the vehicle. The system can further include a vehicle interface configured to electronically communicate with an existing communication bus of the vehicle, such as through a connection with an existing electronics port of the vehicle. A controller of the step system can be configured to process information received from the vehicle interface and, based at least partly on the processing of the information, cause movement of the stepping member between the retracted position and the deployed position.

First claim

What is claimed is:

1. A method of controlling an after-market powered vehicle step system installed on a vehicle, comprising:
electronically obtaining door status information from a digital communication bus of the vehicle, via a pre-existing connector of the vehicle;
electronically processing the door status information according to an algorithm to determine that movement of a stepping deck of the powered vehicle step is appropriate;
transmitting the door status information to electronic componentry of the powered vehicle step system via a wired connection; and
commanding a motor of the powered vehicle step which is drivably coupled to the stepping deck to cause movement of the stepping deck between a retracted position and a deployed position.

2. The method of claim 1 , wherein the door status information is generated by pre-existing componentry of the vehicle.

3. The method of claim 1 , wherein the door status information is generated in response to user actuation of a handle of a door of the vehicle.

4. The method of claim 1 , wherein the door status information is obtained without reliance on disassembly of any portion of any door of the vehicle.

5. The method of claim 1 , wherein the door status information is provided to the step system via an existing electrical connector of the vehicle without reliance on modification of existing electrical componentry of the vehicle.

6. A method of controlling an after-market powered vehicle step system installed on a vehicle, comprising:
electronically obtaining door status information from a digital communication bus of the vehicle;
electronically processing the door status information according to an algorithm to determine that movement of a stepping deck of the powered vehicle step is appropriate; and
commanding a motor of the powered vehicle step which is drivably coupled to the stepping deck to cause movement of the stepping deck between a retracted position and a deployed position,
wherein said electronically obtaining comprises obtaining the door status information via a plug-in connection to the digital communication bus.

7. A powered vehicle step system configured for use with a vehicle system, comprising:
a stepping deck;
a motor drivably coupled to the stepping deck;
a controller configured to:
receive door status information electronically obtained from a digital communication bus of the vehicle;
electronically process the door status information according to an algorithm to determine that movement of the stepping deck is appropriate; and
command the motor to cause movement of the stepping deck between a retracted position and a deployed position,
wherein the system is configured to electronically obtain the door status information via a pre-existing connector of the vehicle, and wherein the door status information is transmitted to electronic componentry of the powered vehicle step system via a wired connection.

8. The system of claim 7 , wherein the door status information is generated by pre-existing componentry of the vehicle.

9. The system of claim 7 , wherein the door status information is generated in response to user actuation of a handle of a door of the vehicle.

10. The system of claim 7 , wherein the door status information is obtained without reliance on disassembly of any portion of any door of the vehicle.

11. The system of claim 7 , wherein the door status information is provided to the step system via an existing electrical connector of the vehicle without reliance on modification of existing electrical componentry of the vehicle.

12. A powered vehicle step system configured for use with a vehicle system, comprising:
a stepping deck;
a motor drivably coupled to the stepping deck;
a controller configured to:
receive door status information electronically obtained from a digital communication bus of the vehicle;
electronically process the door status information according to an algorithm to determine that movement of the stepping deck is appropriate; and
command the motor to cause movement of the stepping deck between a retracted position and a deployed position, wherein the system is configured to electronically obtain the door status information via a plug-in connection to the digital communication bus.
