The application is Third row SUV Power Folding Seats. They are one-touch automated Power Folding Seats. Touch of button folds or unfolds the seat. A embedded control module is connected to DC brush motors. Obstacle Detection Algorithm is running in the control module.
This is closed loop control system. Control module controls motors and motors provide hall pulses to the control module.
Please try to explain following statement:
"Since the gearing of the stow motors are protected by a clutch, it’s not possible to use motor stall to detect the end positions STOW and TAILGATE - resulting in the need to utilize the obstacle detection algorithm to detect these positions."
What are STOW and TAILGATE positions?
