An occupant state detection system includes an occupant monitoring apparatus, an occupant state detection apparatus, and a determination apparatus. The occupant state detection apparatus includes one or more processors and one or more memories. The one or more processors cooperate with one or more programs included in the one or more memories to receive occupant monitoring data from the occupant monitoring apparatus and determination data from the determination apparatus. On the basis of the determination data, the one or more processors make assignment of a part to be monitored, of an occupant in a vehicle, to be monitored by the occupant monitoring apparatus, to detect a physical state of the occupant.

Occupant state detection system

An occupant state detection system includes first and second occupant monitoring apparatuses, a determination apparatus, and an occupant state detection apparatus. The first and second occupant monitoring apparatuses monitor a physical state of an occupant in a vehicle in different methods. The occupant state detection apparatus includes one or more first processors and one or more first memories. Upon receiving data indicating that the vehicle is in a stopped state from the determination apparatus, the one or more first processors cooperate with one or more programs in the one or more first memories to: make assignment of a part to be monitored and data to be acquired, of the occupant in the vehicle, to be detected by the first and second occupant monitoring apparatuses; and detect the physical state of the occupant on the basis of first and second occupant monitoring data from the first and second occupant monitoring apparatuses.

An occupant state detection system includes an occupant monitoring apparatus, a determination apparatus, and an occupant state detection apparatus. The occupant state detection apparatus includes one or more processors and one or more memories. The one or more memories store data including traveling-state comparative data and stopped-state comparative data. The one or more processors cooperate with one or more programs included in the one or more memories to receive occupant monitoring data from the occupant monitoring apparatus and determination data from the determination apparatus. On the basis of the determination data, the one or more processors compare the occupant monitoring data with the traveling-state comparative data on the condition that the vehicle is in the traveling state, and compare the occupant monitoring data with the stopped-state comparative data on the condition that the vehicle is in the stopped state, to detect a state of the occupant in the vehicle.
