Memory seat with soft and hard travel limits
First Claim
1. A vehicle seat system comprising:
- a seat movable along a path;
a motor driving said seat on said path;
a sensor generating a signal indicating the movement of said seat on said path;
a controller activating said motor to move said seat along said path and receiving said signal from said sensor, said controller ceasing activation of said motor and defining a first soft limit when said sensor detects that said movement of said seat has stopped for a first predetermined time interval at a first position, said controller ceasing activation of said motor and defining a first hard limit when said sensor detects that said movement of said seat has stopped for a second predetermined time interval at said defined first soft limit, said second predetermined time interval less than said first predetermined time interval.

Abstract
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.

6. A method for controlling a vehicle seat system including the steps of:
-
a) moving a seat along a path to a first position where said seat contacts a travel limit; b) detecting that movement of said seat has stopped at said first position on said path; c) defining a first soft limit at said first position based upon said step b); d) moving said seat along said path to said first soft limit and causing said seat to contact said travel limit; e) detecting that movement of said seat has stopped at said first soft limit; f) defining a first hard limit at said first soft limit based upon said step e); g) moving said seat along said path toward said first hard limit; and h) ceasing movement of said seat along said path before detecting that movement of said seat has stopped at said first position. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

16. A vehicle seat system comprising:
-
a seat moveable along a path; a motor driving said seat on said path; a sensor generating a signal indicating the movement of said seat on said path; a controller receiving said signal from said sensor, said controller defining a first soft limit at a first position on said path based upon said controller detecting that movement of said seat has stopped at said first position for a first predetermined time interval based upon said signal from said sensor, said controller ceasing movement of said seat along said path upon detecting that movement of said seat has stopped at said first soft limit for a second predetermined time interval less than said first predetermined time interval based upon said signal from said sensor. - View Dependent Claims (17)
