AI Technical Summary
Technical Problem
In existing technologies, seat Hall sensors are prone to positional shifts after repeated adjustments, leading to a decline in user experience, and existing solutions increase overall vehicle cost or hardware complexity.
Method used
By dynamically adjusting the percentage amplification factor of the seat motor, the minimum step size accuracy within the software is ensured to be equal to or correspond to one Hall effect value, avoiding rounding errors, achieving closed-loop control, and avoiding hardware modifications.
Benefits of technology
It effectively prevents Hall position deviation, improves user comfort, reduces the cost of vehicle seat anti-deviation control, and reduces manual correction operations.

Abstract
This invention belongs to the field of automotive seat control technology, providing a variable-precision seat anti-Hall offset control method, system, and application. The method includes: acquiring the track length of the seat motor's running path; comparing the total Hall effect count with a reference value, dynamically selecting a percentage amplification factor calculation strategy, and setting the minimum step precision of the percentage position within the software so that the minimum step precision equals or corresponds to one Hall effect count; multiplying the target position percentage by the percentage amplification factor to obtain the target percentage value within the software, and calculating the target Hall effect position; after the seat motor reaches the target Hall effect position and stops, dividing the current percentage value within the software by the percentage amplification factor to obtain the true percentage position of the seat motor and providing feedback for closed-loop control of the seat motor's position. This invention does not involve any hardware changes and solves the problem of Hall effect offset caused by repeated seat movement through a variable-precision software adjustment method.
