Integrated one touch up and down windowlift motor with direct sense for anti-pinch
First Claim
1. A windowlift control system for controlling movement of a window of a vehicle, the system comprising:
- a DC brush motor constructed and arranged to cause movement of the window up and down, and electronics integral with the motor constructed and arranged to control the motor to selectively move the window up and down, the electronics including;
analog obstruction signal input constructed and arranged to receive an analog obstruction signal from an obstruction sensor, associated with the window, that directly senses an obstruction in a travel path of the window, digital obstruction signal input constructed and arranged to receive a digital obstruction signal from an obstruction sensor, associated with the window, that directly senses an obstruction in a travel path of the window, and switch decoding inputs constructed and arranged to signal manual mode of operation of the motor to move the window in a manual up or down mode, and a one-touch mode of operation of the motor to move the window in an express up or an express down mode, whereby during the one-touch up mode of operation, the electronics is constructed and arranged to cause the motor to stop and reverse in the express up mode when the digital obstruction signal input or the analog obstruction signal input indicates that an obstruction is in a path of the upwardly moving window.

Abstract
A windowlift control system 10 is provided for controlling movement of a window of a vehicle. The system 10 includes a DC bush motor 12 constructed and arranged to cause movement of the window up and down, and electronics 14 integral with the motor for controlling the motor to selectively move the window up and down. The electronics includes analog obstruction signal inputs 18, 20 for receiving analog obstruction signals from an obstruction sensor 16, associated with the window, that directly senses an obstruction in a travel path of the window. The electronics includes digital obstruction signal inputs 22, 24 for receiving digital obstruction signals from an obstruction sensor 16′, associated with the window, that directly senses an obstruction in a travel path of the window. The electronics also includes switch decoding inputs 23, 25, 27 for signaling a manual or one-touch up mode of operation of the motor to move the window in an upward direction. The signal decoding inputs also allow for a manual or one touch down mode of operation of the motor to move the window downwardly.
