Position and speed determination for a closure

摘要

A control (36) utilizes a unique linear motor for a vehicle closure system (20) that has a plurality of rungs (26) crossing between side pieces. The rungs (26) are made to provide an individual signal to a sensor (34) such that the sensor (34) can identify the location of the closure (21) as it passes the rungs (26). In one example the distance between adjacent rungs (26) is varied such that each of the distances are unique. In this way, the control (36) can identify the actual location of the closure (21) by identifying the particular signal. In other embodiments the rungs (26) are made to each be individual in some fashion. As an example, the size of each rung can be varied.
