发明名称 Adjustable motor control circuit for power windows
摘要 <p>An apparatus (10) and a method for controlling a power window drive motor (12). A first RC circuit (110, 106) is used to provide a first time limit and a second RC circuit (114, 106) is used to provide a second time limit. A switch (28) is actuatable to provide a signal having a time duration. A logic circuit (132) determines whether the time duration of the signal from the switch (28) exceeds the first time limit. The motor (12) is operated to move a window (14) through a predetermined range of movement responsive to the time duration of the signal from the switch (28) exceeding the first time limit. The logic circuit (132) determines whether the time duration of operation of the motor (12) exceeds the second time limit. The motor (12) is stopped responsive to the time duration of operation of the motor exceeding the second time limit. The second time limit is set independent of the first time limit using two exchangeable resistors (110, 114).</p>
