United States Patent 10666901
Abstract:
A system in a vehicle comprises one or more sensors configured to obtain occupant information indicating a stress level of an occupant of the vehicle. The system also includes a wireless transceiver in communication with a mobile device including a camera configured to monitor the occupant, and a controller in communication with the one or more sensors and the wireless transceiver, wherein the controller is configured to determine a stress-level of the occupant utilizing at least the occupant information, initiate a video conference session on the mobile device between the occupant and one or more contacts of the occupant in response to the determination of the stress level of the occupant exceeding a threshold, and output on a vehicle display the video conference between the occupant and the one or more contacts.

An in-vehicle camera 103 may be mounted in the vehicle to monitor occupants (e.g. a driver or passenger) within the vehicle cabin. The in-vehicle camera 103 may be part of an occupant status monitoring system (OSM). The in-vehicle camera 103 may be utilized to capture images of an occupant in the vehicle. The in-vehicle camera 103 may obtain facial information about an occupant, such as eye-movement of the occupant and head-movement of the occupant, as discussed further below. The in-vehicle camera may be a color camera, infrared camera, or time of flight camera. The in-vehicle camera 103 may be mounted on a head rest, in the headliner, or located on a mobile device (e.g. tablet or mobile phone) to capture the driver's face, especially the driver's eyes.
A controller may receive driver status data from the OSM to determine an abnormal situation within the vehicle. The OSM employs one or more activity sensors such as a driver-facing camera, an occupant-facing camera, a health scanner, and an instrument panel to monitor activities performed by the driver or occupants (e.g. passengers in the vehicle). Based on the activity sensors, the OSM may determine whether the driver is, for example, distracted, sick, or drowsy as the abnormal situation.
A controller may receive occupant status data from the OSM to determine an abnormal situation within the vehicle. The OSM may employ one or more activity sensors such as a occupant-facing camera, a health scanner, and an instrument panel to monitor activities performed by occupants. For example, an occupant-facing camera may be employed in a vehicle headliner, vehicle headrest, or other area of the vehicle to monitor activity of the occupant. The OSM may also employ a mic that is in communication with a voice recognition (VR) engine that can detect fussiness of a child (e.g. baby) or irregular crying or sounds from the child. Based on the activity sensors, the OSM may determine whether the occupant or driver is, for example, fuss, experiencing motion sickness, hunger and fever.
