Retractable truck step with can bus interface
First Claim
1. A controller area network (CAN) bus interface that controls an entry and exit step comprising:
- a CAN node on a vehicle;
said CAN node monitors a CAN bus to detect when action from a person requires an entrance and exit step to be extended or retracted;
said action from said person changes a door opening or closing;
upon said action said CAN node commands said exit step to extend or retract;
said command is a wired command or a wireless command, andsaid CAN node is added to a pre-existing vehicle CAN bus vehicle.

Abstract
Improvements using a door sensors or monitoring the vehicle CAN bus to determine when a door is opened or closed to simplify installation of a retractable door step to send a wireless or wired command to a step. Upon door movement the transmitter sends an open status message to a receiver where the message data is stored and the controller determines the correct responses. The step remains lowered until the receiver stops receiving messages indicating a door is closed or the transmitter on an open door has timed out ceasing transmissions. The step extension mechanism is a two-bar link that transfers rotation from a sealed waterproof motor and transmission to extend and retract the step.

7. A retractable truck step with wireless door sensor comprising:
-
at least one motor connected to at least one transmission that extends and retracts at least one automated vehicle entrance and exit step; said at least one automated vehicle entrance and exit step is placed at a driver side of said vehicle and at a passenger side of said vehicle; said least one motor that is connected to at least one transmission is sealed from water intrusion; at least one sensor that detects when a door is opened and or closed; said sensor emitting a wireless signal to a receiver when said door is opened and closed; said wireless signal includes vehicle ID information, and a receiver that receives said emitted wireless signal to operate said motor. - View Dependent Claims (8, 9, 10, 11, 12)

13. A retractable truck step with controller area network (CAN) bus interface comprising:
-
a CAN node on a vehicle; said CAN node monitors a CAN bus to detect when action from a person requires an entrance and exit step to be extended or retracted; said action from said person is a change in a door opening or closing; at least one motor connected to at least one transmission that extends and retracts at least one automated vehicle entrance and exit step; said at least one automated vehicle entrance and exit step is placed at a driver side of said vehicle and at a passenger side of said vehicle, and upon said action said CAN node commands said at least one motor to extend or retract said at least one automated vehicle entrance and exit step, and said at least one transmission is with a torsion bar link between said at least one motor and at least one idler linkage. - View Dependent Claims (14, 15, 16, 17)
