摘要： A system is provided for utilizing belt movement information in a motorized seat belt (MSB) control system algorithm to achieve better levels of comfort and safety. The MSB control system algorithm controls execution of multiple modes including a no friction mode, a stowage mode, a slack reduction mode, an out of position warning mode, a medium pull-back mode, and a high pull-back mode. The MSB control system algorithm also controls execution of a low power mode initiated after the other vehicle modules are put to sleep to provide the ability to stow the seat belt after the vehicle has been turned off for some period of time. The MSB control system algorithm also controls belt monitoring functions defined based on a buckle switch state that indicates the buckled or unbuckled state of the seat belt. Belt monitoring consists of belt movement being converted to counts based on a resolution provided by a belt movement sensor.
