A system to detect an occupant left in a vehicle includes a sensor, a determiner, and a controller. The sensor outputs a radio wave and detects a wave reflected by the occupant being left in the compartment. The determiner determines whether the occupant is left in the compartment, at least based on a detection result from the detected reflected wave. The controller selects a radio wave to be output from the sensor from those of different frequencies including a first radio wave a second radio wave lower in frequency than the first radio wave. The controller is configured to switch from the first radio wave to the second radio wave when the occupant is leaving the vehicle, and cause the determiner to determine whether the occupant is left, based on a detection result from the reflected wave detected by the sensor which output the second radio wave.

System for detecting occupant being left in vehicle

A vehicle-interior monitoring apparatus for a vehicle includes a sensor and a determiner. The sensor is configured to output a millimeter radio wave toward a vehicle cabin of the vehicle and detect a millimeter reflection wave from an in-vehicle object including an occupant in the vehicle cabin of the vehicle and baggage in the vehicle cabin of the vehicle. The determiner is configured to determine a type of the in-vehicle object in the vehicle cabin of the vehicle based on a detection level of the millimeter reflection wave detected by the sensor. The determiner is configured to perform a determination, the determination including determining that the in-vehicle object is either one of a child as the occupant or the baggage based on a tendency of a change in the detection level of the millimeter reflection wave detected by the sensor.

Vehicle-interior monitoring apparatus

An attachment structure of a vehicular module to a ceiling of a vehicle cabin of a vehicle includes a design member. The design member is configured to attach, to the ceiling, the module including an in-cabin sensor configured to perform detection in the vehicle cabin, and includes a securing portion configured to be secured to a vehicle-body ceiling member of the vehicle or an interior ceiling member disposed on a vehicle cabin side of the vehicle-body ceiling member, a downward protrusion protruding downward from the securing portion, and a design constituent extending from the downward protrusion and covering the securing portion. In an accommodating space defined between the downward protrusion and the design constituent, the in-cabin sensor is supported by the design member in such a manner that, above the accommodating space, a gap is left between the in-cabin sensor and the vehicle-body ceiling member or the interior ceiling member.

Attachment structure of vehicular module to ceiling of vehicle cabin

A vehicle-interior monitoring apparatus for a vehicle includes a millimeter-wave sensor, a determiner, and a movement sensor. The millimeter-wave sensor outputs a millimeter radio wave toward a vehicle cabin of the vehicle and detects a millimeter reflection wave from an in-vehicle object including either one of an occupant and baggage in the vehicle cabin. The determiner determines a type of the in-vehicle object based on a detection level of the detected millimeter reflection wave. The movement sensor detects movement of the vehicle. The determiner re-determines that a determined in-vehicle object is either one of the baggage and a child as the occupant based on a positional change of the determined in-vehicle object upon the movement sensor detecting the movement of the vehicle, the determined in-vehicle object being the in-vehicle object of which the determiner has determined the type based on the detection level of the millimeter reflection wave.

An alert system configured to output an alert about an occupant being left in a vehicle includes an external-environment camera, a determiner, and an alert controller. The external-environment camera captures images at least one of which includes the occupant outside the vehicle. The determiner determines whether a child including an infant is likely to have been left in the vehicle. The alert controller outputs an alert if the child is likely to have been left in the vehicle. The determiner determines whether the child is likely to have been left in the vehicle, based on a change in the images from one of a presence state and an absence state of a person or an object outside the vehicle in a first image of the images to another of the presence state and the absence state of the person or the object in a second image of the images.

Alert system to output alert about occupant left in vehicle

An alert system outputs one or more alerts about an occupant being left in a vehicle. The alert system includes an in-vehicle object detector and an alert controller. The in-vehicle object detector detects objects in a vehicle compartment, including the occupant. If the occupant is left in the compartment after a driver has left the vehicle, the alert controller controls outputting of the one or more alerts to mobile terminals of persons including the driver. If the driver has left the vehicle, the alert controller causes the in-vehicle object detector to begin a detection processing for detecting the occupant being left in the compartment. If the occupant is left in the compartment, the alert controller determines whether the mobile terminal of the driver is left in the compartment. The alert controller switches outputting of the one or more alerts to among the mobile terminals of the persons in accordance with whether the mobile terminal of the driver is left in the compartment.

Alert system for vehicle to output alert about occupant being left in vehicle

An alert system includes an in-vehicle object detector and an alert controller. The in-vehicle object detector detects objects in a vehicle compartment, including an occupant. The alert controller is configured to control execution of alert output operations if the occupant is left in the compartment after the vehicle's driver has left the vehicle. The alert output operations include at least an output operation of an alert to a mobile terminal of the driver. The alert controller is configured to cause the in-vehicle object detector to begin a detection processing for detecting the occupant being left in the compartment if the driver has left the vehicle, determine whether the mobile terminal of the driver is left in the compartment, and switch between the alert output operations in accordance with whether the mobile terminal of the driver is left in the compartment.
