Abstract
Disclosed is an anti-pinch control system. The anti-pinch control system includes a motor configured to generate driving force for moving a seat of a vehicle, a current measurement sensor configured to measure a current value generated in the motor, a hall sensor configured to measure a revolution per minute (RPM) of the motor, and a controller configured to derive an average of current values measured by the current measurement sensor during an edge generating time during which a specific number of edges are generated by the hall sensor, and to set, to an anti-pinch value, a value obtained by adding a rising value, corresponding to current that increases when a pinch occurs in the seat, to the average, wherein the controller derives the average for each specific RPM and updates the anti-pinch value.
Claims11
An anti-pinch control system comprising:
- a motor configured to generate driving force for moving a seat of a vehicle;
- a current measurement sensor configured to measure a current value generated in the motor;
- a hall sensor configured to measure a revolution per minute (RPM) of the motor;
- and
- a controller configured to derive an average of current values measured by the current measurement sensor during an edge generating time during which a specific number of edges are generated by the hall sensor, and to set, to an anti-pinch value, a value obtained by adding a rising value, corresponding to current that increases when a pinch occurs in the seat, to the average,
- wherein the controller derives the average for each specific RPM and updates the anti-pinch value.
