SYSTEM AND METHOD FOR SENSORLESS REMOTE RELEASE ACTUATING SYSTEM
First Claim
1. A method for configuring a controller to operate a motor to position a seat, the controller including an integrated current sensor, the seat including a latch operatively coupled to the motor, the method comprising:
- determining an operating profile of the motor under one or more operating conditions, wherein the operating profile represents motor current values during activation of the latch, and wherein the activation of the latch includes at least one latch pulling condition and one latch release condition;
analyzing the operating profile in order to correlate the profile to the position of the latch; and
loading the controller with instructions to enable comparison of a real-time current measured by the integrated current sensor to the stored operating profile, wherein the analysis enables determination of the latch condition in real-time.

Abstract
A method for configuring a controller to operate a motor to position a seat, in which the controller includes an integrated current sensor and the seat includes a latch operatively coupled to the motor, includes determining an operating profile of the motor under one or more operating conditions, wherein the operating profile represents motor current values during activation of the latch, and wherein the activation of the latch includes at least one latch pulling condition and one latch release condition. The method further includes analyzing the operating profile in order to correlate the profile to the position of the latch. The method also includes loading the controller with instructions to enable comparison of a real-time current measured by the integrated current sensor to the stored operating profile, wherein the analysis enables determination of the latch condition in real-time.

9. A method for controlling the operation of a motor to position a seat, the seat including a latch operatively coupled to the motor, the motor including a controller with an integrated current sensor and a pre-determined operating profile of the motor during operation of the latch, the method comprising:
-
initiating operation of the motor; obtaining real-time motor current values from the current sensor; comparing the motor current values to the pre-determined operating profile; determining if the latch has released; and based on the determination, ceasing or continuing operation of the motor. - View Dependent Claims (10, 11, 12, 13)

14. A remote release actuating system for releasing a vehicle seat latch, the seat latch coupled to a cable including at least one latch pulling condition and one latch release condition, the system comprising:
-
a gear assembly including a gear case containing a transmission, the gear assembly coupled to the cable; a biasing member configured to bias the cable in a first position; and a motor having an output shaft operatively coupled to the gear assembly, the motor further including a motor driver with a solid state switch and an integrated current sensor to provide a measurement of the current flowing to the motor; and a controller loaded with an operating profile of the motor, the controller configured to compare the current obtained from the current sensor to the operating profile and determine the state of the latch without the use of a position sensor. - View Dependent Claims (15, 16, 17, 18)
