Disclosed are a seat belt wireless communication system and method. The seat belt wireless communication system includes sensing units provided in respective seats and configured to sense whether or not to fasten seat belts, sub-ECUs provided in the respective seats and configured to transmit signals indicating whether or not to fasten the seat belts, sensed by the sensing units, through wireless communication, and a main ECU provided in a vehicle and configured to perform wireless communication with the respective sub-ECUs, to wake up the sub-ECUs through wireless communication, to determine whether or not to fasten the seat belts of the respective seats by receiving the signals from the sub-ECUs after wake-up of the sub-ECUs, and to determine, when the main ECU does not receive a corresponding one of the signals from at least one of the sub-ECUs B, that the corresponding sub-ECU has failed.

The present invention relates to an anti-abandonment system comprising: a first sensor (2) associable with a restraining device (R) placed in the vehicle, a second sensor (3) associable with a fastening tab or with a fastening buckle of a safety belt of the vehicle. The anti-abandonment system comprises a control unit connected to the first and second sensors and configured to perform a control procedure comprising the steps of: determining, as a function of the signal emitted by the first sensor, the presence of a child and/or an infant on the restraining device; determining, as a function of the signal emitted by the second sensor, a fastened or unfastened condition of the safety belt, defining an alarm condition in the event that the control unit determines the presence of a child and/or an infant on the restraining device and at the same time the unfastened condition of the safety belt. The present invention also regards a process for warning of a potentially hazardous situation relative to the presence of an infant/child inside a vehicle.

The techniques of this disclosure relate to a vehicle occupancy-monitoring system. The system includes a controller circuit that receives occupant data from an occupancy-monitoring sensor of a vehicle. The controller circuit determines an occupancy status of respective seats in a cabin of the vehicle based on the occupancy-monitoring sensor. The controller circuit indicates the occupancy status of the respective seats on a display located in a field of view of occupants of the vehicle. The display is integral to one of a roof light module, a door panel, or a headliner of the cabin. The system can improve passenger safety by alerting the operator and other occupants about the occupancy status of the passengers.
