Automatic automotive power window system and method of controlling an automatic automotive power window system
First Claim
1. An automotive power window system comprising:
- a motor arranged for mechanically actuating a window regulator mechanism for moving a window glass between an open position and a closed position;
a first signal link and a second signal link each coupling the motor to a controller, the controller being physically remotely located from the motor;
the first signal link arranged for communicating a high priority data at a high data rate, the high priority data being associated with motor operation in an automatic operating mode; and
the second signal link arranged for simultaneously with communication of the high priority data on the first signal link communicating a low priority data at a low data rate, the low priority data being associated with operating commands for the motor.

Abstract
An automatic power window system (10) includes a motor module (12) and a controller (14) physically remotely located from the motor module. The motor module and the controller are coupled by a first signal link (16) and a second signal link (18). The first signal link is arranged to carry a limited number of high priority communication data at high speed, while the second signal link is arranged to carry virtually any number of low priority communication data at low speed. The high priority communication data may represent an operating condition of the motor during automatic operation. The operating condition is preferably simply and reliably indicated by the presence, absence or transition of a signal on the first signal link. The low speed communication data represents a plurality of operating data each of which are indicated by a plurality of time-multiplexed signals.

10. A system for automatic actuation of a window regulator within a motor vehicle comprising:
-
a motor operatively coupled to the window regulator for providing driving torque thereto; a controller physically remotely located from the motor; a first signal link coupling the motor to the controller, a second signal link coupling the motor to the controller and a power signal link coupling the motor to the controller each of the first signal link, the second signal link and the power signal link comprising a separate physical connection; the motor including a signal generator for generating a high priority data signal on the first signal link at a high data rate; the second signal link arranged for communicating a low priority data signal at a low data rate, the low priority data being associated with operating commands for the motor; and the controller including a signal detector for detecting a presence of the signal on the first signal link, the controller being responsive to the presence for coupling electrical power to the motor over the power signal link for automatic operation. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of automatically operating a power window system in a motor vehicle, the power window system including a window regulator arranged for opening and closing a window glass, a motor coupled to the window regulator for providing driving torque thereto, a controller physically remotely located from the motor, a first signal link coupling the motor and the controller, a second signal link coupling the motor and the controller and a power signal link coupling the motor and the controller, the method comprising the steps of:
-
detecting one of a presence, an absence and a transition of a signal on the first signal link; and responsive to one of the presence, the absence and the transition of the signal, selectively permitting automatic operation. - View Dependent Claims (17, 18, 19, 20)
