Method for controlling seat adjuster of motor vehicle, by which the range of adjustment is divided into large number of coded incremental steps monitored by incremental generator and sensor

摘要

The adjustment range of a seat is divided into a large number of coded incremental steps. At intervals, mechanical position stops (MA1,MA2) are set, monitored by an incremental generator and sensor to determine the actual position of the seat. Before each stop, a soft stop (SS1,SS2) is designated, set, e.g. by the control system based on the occupants weight. Errors in the control and monitoring systems can result in an error between measured and actual positions so that the soft stop requires to be reset. For this, zones (EB1,EB2) are set in which it is permissible to reset the soft stop.
