1. A latch control method, comprising the steps of:
- providing a latch, which receives power from a motor associated with an H-bridge circuit;
monitoring said latch with a magnetoresistive sensor that obtains latch feedback data from said latch; and
controlling said latch based on said latch feedback data utilizing a microcontroller, which controls said latch, by controlling an interaction of said H-bridge circuit and said motor with said latch, wherein an output of said microcontroller is proportional to an error or a change in a measurement derived from said sensor and said latch.

Abstract
Latch control methods and systems include a latch that receives power from a motor associated with an H-bridge circuit. A sensor can be provided for monitoring the latch, wherein the sensor obtains latch feedback data from the latch. A microcontroller controls the latch based on the latch feedback data, by controlling an interaction of the H-bridge circuit and the motor with the latch. Additionally, a microprocessor processes instructions for controlling the interaction of the H-bridge circuit and the motor with the latch. Such instructions can be implemented as Proportional Integral Derivative (PID) control instructions.
