Abstract:
A system for synchronizing the operation of multiple actuators used to extend and retract a slide-out room of a vehicle, the system comprising:a first slide assembly including a first slide member adapted to be connected to the slide-out room, the first slide member moveable relative to a stationary member of the vehicle along a path of travel between an extended and a retracted position; a second slide assembly including a second slide member adapted to be connected to the slide-out rooe remote from the first slide member, the second slide member moveable relative to the stationary member of the vehicle along any starting position of the path of travel between an extended and a retracted position; first and second powered actuators operably coupled to the first and second slide members, respectively, for moving the first and second slide members between extended and retracted positions; first and second sensors operably associated with the first and second slide members, respectively, the first and second sensors operable for generating signals indicative of the relative position of the first and second slide members at any position along the path of travel between the extended and retracted positions; and a synchronization controller in electrical communiaction with the first and second sensors and the first and second powered actuators, the synchronization controller operable to monitor the generated signals and adjust the relative distance of travel of the slide members so as to enable the slide members to extend or retract in substantial unison to a completed position.
