Referring to
The detecting the status of a door may include performing an image analysis by comparing the at least one image with a pre-stored baseline image of the vehicle or vehicle opening and/or determining a distance between reference points in the at least one image. The image analysis may then be used to determine whether one or more from among a window, a moon roof, a hood, a front passenger side door, a rear passenger side door, a front driver side door, a rear driver side door, and a rear hatch or trunk are and output a status indicating which doors from among the front passenger side door, rear passenger side door, front driver side door, rear driver side door, and rear hatch or trunk are ajar.
It is then determined whether a function from among a plurality of functions is to be performed based on the detected status of the door in operation S220. For example, it may be determined to alert of the status of the door when one or more from among a front passenger side door, a rear passenger side door, a front driver side door, a rear driver side door, and a rear hatch or trunk is detected to be open by a vehicle camera such as an external facing vehicle camera. Other conditions for alerting of the status of the door may also be considered by the determining whether to alert of the status of the door. The one or more conditions may include whether an occupant is present or not present in the vehicle, whether the driver, mobile device of the driver, or key of the vehicle are present in the vehicle or are moving away from the vehicle, and the state of the transmission of the vehicle.
The plurality of functions may also include one or more from among vehicle theft alarm control, interior lighting control, park assist control, vehicle running board up and down control, engine control, inhibiting start/stop functions of a vehicle, preparing engine for startup, adaptive cruise control, and loading an occupant profile including settings such as seat position, steering wheel position, infotainment settings, etc., from memory. Another example of a function that may be performed may be to detect ingress or egress of an occupant based on the detected status of the door or openings of a vehicle. For example, a sequence of door openings and closings and initiation or operation of vehicle functions and controls may be detected and analyzed to determine which seats have occupants and whether occupants are entering and leaving a vehicle.
In operation S230, the determined function is performed. For example, a notification alerting of the status of the door is output if the determining determines to alert of the status of the door. The outputting the notification may include displaying an indicator including a graphical illustration corresponding to the status of the one or more doors. Moreover, the outputting may include transmitting the alert to a mobile device of a user if the occupant is not present in the vehicle. In addition, if one or more of aforementioned conditions are met, the notification may be displayed on a display in the vehicle or may be transmitted to mobile device associated with an operator or owner of the vehicle.
The image from the side view camera may be analyzed to determine which combination of doors, windows, and/or entrances to a vehicle are open. For example, the image from the side view camera may be analyzed to determine whether one or more from among the front passenger side door, rear passenger side door, front driver side door, and rear driver side door are open.
