摘要： A vehicle seat system includes a motor moving a seat along a path between mechanical limits. A sensor measures the position of the seat along the path. A control module defines a soft-limit when the sensor detects that movement of the seat has stopped for a first predetermined time interval, but the motor is activated. The control module subsequently ceases movement of the seat at the soft-limit when no movement of the seat is detected for a second predetermined time interval less than the first predetermined time interval, indicating a soft stall. The control module defines a hard-limit after a predetermined number of soft stalls. The control module subsequently ceases activation of the motor just before the seat reaches a hard-limit.
