Method for operating a power sliding door and a power liftgate using remote keyless entry system
First Claim
1. A method for controlling the operation of at least one power sliding door and a power liftgate in a minivan, said method comprising:
- providing a RKE system user input interface comprising a RKE transmitter and a RKE receiver;
monitoring said RKE system for a change of state in a first control module;
producing an actuation signal in response to a user request in said RKE system;
receiving said actuation signal from said RKE system in a first control module;
interpreting said actuation signal in said first control module;
determining an action in response to said actuation signal in said first control module comprising monitoring status inputs from an ignition switch and monitoring gear position information from a transmission controller;
broadcasting an actuation message by said first control module;
receiving an actuation message from said first control module in a second control module; and
directing the movement of at least one of said at least one power sliding door and said power liftgate in a second control module utilizing at least one electric motor.

Abstract
A method for operating a power sliding door and a power liftgate in an automobile, such as a minivan, using a remote keyless entry (RKE) is comprised in a control system that includes a user input interface for receiving sliding door actuation requests from a user. The actuation signals are carried to a body control module (BCM) where the request is broadcast to a power sliding door module (PSDM) over a serial data bus communications network meeting the SAE J1850 multiplex communications protocol standard. Upon receipt of the actuation message the PSDM monitors several operating conditions of the automobile and makes a determination whether or not to carry out the power sliding door activation request. Power sliding door actuation is controlled by the PSDM via electric motors located at or near the power doors. A power liftgate module (PLGM) controls the power liftgate actuation upon via electric motors located at or near the liftgate. The user input interface includes interior switches as well as a RKE system.

8. A method for controlling the operation of at least one power sliding door and a power liftgate in a minivan, said method comprising:
-
providing a RKE system user input interface comprising a RKE transmitter and a RKE receiver, said RKE transmitter comprising a plurality of input switches, said input switches comprising an unlock switch, a lock switch, a left doors switch, a right doors switch, a liftgate switch and a panic switch, and wherein said RKE transmits a radio frequency signal to said RKE receiver; monitoring said RKE system for a change of state in a first control module; producing an actuation signal in response to a user request in said RKE system; receiving said actuation signal from said RKE system in a first control module; interpreting said actuation signal in said first control module; determining an action in response to said actuation signal in said first control module comprising monitoring status inputs from an ignition switch, monitoring gear position information from a transmission controller, and disregarding an activation input originating from said RKE system when a first status input is received from said ignition switch and said gear position monitored from said transmission controller indicates that said minivan is not in park; broadcasting an actuation message by said first control module; receiving an actuation message from said first control module in a second control module; and directing the movement of at least one of said at least one power sliding door and said power liftgate in a second control module utilizing at least one electric motor. - View Dependent Claims (9, 10, 11, 12)
