Abstract

A method for configuring a controller to operate a motor to position a seat, wherein the controller includes an integrated current sensor, the seat includes a buckle operably coupled to the motor, the method includes determining one or more An operating curve of the motor under an operating state, wherein the operating curve represents a motor current value during the triggering of the locker, and wherein the triggering of the locker includes at least one of a locker tightened state and a locker unlocked state . The method further includes analyzing the operational curve to correlate the curve with a position of the buckle. The method further includes loading the controller with instructions to enable comparison of the real-time current measured by the integrated current sensor with a stored operating curve, wherein the analysis enables real-time determination of the latch state.

Description

Background technique [0001] The present invention relates to a remote release actuation system for retracting and releasing a cable. [0002] Many conventional actuation systems, such as those used for seat adjustment, use external position sensors (eg, encoders, resolvers, Hall effect sensors, potentiometers, etc.) to provide position feedback to the controller. While operationally adequate for this purpose, external position sensors add additional cost and weight to the system and are often susceptible to failure. Contents of the invention [0003] In one embodiment, the present invention provides 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 lock operatively coupled to the motor buckle. The method includes determining the operating curve of the motor in one or more operating states, wherein the operating curve represents motor current values ​​during activation of ...
