Vehicle-Occupant Alert System

A method comprising:

• receiving occupant data, including radar data, from an occupancy-monitoring sensor configured to detect a presence of at least one object inside a vehicle;
• determining whether an operator of the vehicle has exited the vehicle based on the occupant data;
• responsive to detecting a presence of the at least one object inside the vehicle, determining, based at least in part on the radar data, a classification of the at least one object;
• responsive to determining the classification of the at least one object, determine, based on the occupant data, that the at least one object remains inside the vehicle for a time exceeding a first threshold since the operator has exited the vehicle, the first threshold determined based in part on the classification of the at least one object;
• and
• output an alert indicating that the at least one object remains inside the vehicle when the time exceeds the first threshold.

A computer-readable storage media comprising instructions that, when executed, configure at least one processor to:

• receive occupant data, including radar data, from an occupancy-monitoring sensor configured to detect a presence of at least one object inside a vehicle;
• determine whether an operator of the vehicle has exited the vehicle based on the occupant data;
• responsive to detecting a presence of the at least one object inside the vehicle, determine, based at least in part on the radar data, a classification of the at least one object;
• responsive to determining the classification of the at least one object, determine, based on the occupant data, that the at least one object remains inside the vehicle for a time exceeding a first threshold since the operator has exited the vehicle, the first threshold determined based in part on the classification of the at least one object;
• and
• output an alert indicating that the at least one object remains inside the vehicle when the time exceeds the first threshold.
