US Patent 10377342 Self-driving vehicle systems and methods

A seat-belt monitoring system can be used with self-driving vehicles. A self-driving vehicle can include a belt sensor configured to detect a buckled state of a seat belt. The self-driving vehicle can include an occupancy sensor configured to detect a rider sitting in a seat. The seat-belt monitoring system can receive buckle and occupancy data from multiple self-driving vehicles and then can respond in ways configured to promote increased seat belt use.
