Preferred exemplary embodiments will hereinafter be described in conjunction with the appended drawings, wherein like designations denote like elements, and wherein:
There is provided a system and method for carrying out an evacuation drill for a vehicle in which occupants are evacuated from the vehicle. The system, which may be referred to as a vehicle evacuation drill monitoring system, is used to carry out the method, which is a method of carrying out an evacuation drill for a vehicle in which one or more occupants are evacuated from the vehicle. At least according to embodiments, the method includes the steps of: receiving a vehicle evacuation drill start input at a vehicle from an evacuation drill operator conducting an evacuation drill; initiating an evacuation countdown timer that defines a temporal extent of an evacuation phase of the evacuation drill in which one or more occupants are to evacuate a passenger cabin of the vehicle; and when it is determined that no occupants remain within the passenger cabin of the vehicle at of or before expiration of the evacuation countdown timer, providing an evacuation drill successful execution indicator indicating that the evacuation drill was successful.
According to embodiments, the vehicle evacuation drill monitoring system includes one or more occupant detection sensors (e.g., life detection sensors) installed in a vehicle, as well as a controller subsystem configured to receive sensor data from the one or more occupant detection sensors and to perform the method of carrying out an evacuation drill for the vehicle in which one or more occupants are evacuated from the vehicle. In embodiments, the vehicle evacuation drill monitoring system further includes a human-machine interface (HMI) output device, such as an audio speaker or an electronic display (e.g., liquid crystal display (LCD) screen), which is configured to receive an evacuation drill execution indicator from the controller subsystem and to provide the evacuation drill execution indicator to a user, such as an evacuation drill manager overseeing the vehicle evacuation drill. The evacuation drill execution indicator may be an evacuation drill unsuccessful execution indicator, evacuation drill successful execution indicator, or an evacuation drill incomplete execution indicator.
According to embodiments, the method further includes a fake evacuation drill detection mechanism that determines whether there are occupants present within the passenger cabin of the vehicle prior to beginning an evacuation phase of the evacuation drill. In embodiments, the fake evacuation drill detection mechanism is performed by activating occupant detection sensors that detect occupants present within a passenger cabin of the vehicle, which may be carried out in response to receiving the vehicle evacuation drill start input. The evacuation phase refers to a portion of the evacuation drill in which occupants are to evacuate the passenger cabin of the vehicle, which extends temporally from an evacuation start time to an evacuation end time. According to implementations, the fake evacuation drill detection mechanism enables verification of an evacuation drill being carried out at the vehicle through detecting occupants within the vehicle, such as within a passenger cabin of the vehicle. More specifically, the fake evacuation drill detection mechanism enables verification that occupants are located within the vehicle (specifically, the passenger cabin) at or prior to an evacuation start time whereat the evacuation phase of the evacuation drill begins.
According to embodiments, there is provided a data management hub that is configured to obtain vehicle evacuation drill execution results (e.g., the evacuation drill successful execution indicator, the evacuation drill unsuccessful execution indicator) from vehicle evacuation drill monitoring systems. In this regard, the data management hub is also referred to as an evacuation drill monitoring data hub or system that includes a computer system that is configured to receive vehicle evacuation drill execution results, which may be accompanied with other, related data, such as identification (e.g., phone number) of the evacuation drill operator (or vehicle operator, which may be the same individual), date and time of the vehicle evacuation drill execution results, and an amount of time the evacuation drill (or portion thereof, such as the evacuation phase) took.

With reference to
The method 200 begins with step 210, wherein a vehicle evacuation drill start input is received from an evacuation drill operator. The evacuation drill operator is the person conducting a vehicle evacuation drill at a vehicle and, where more than one person is conducting the vehicle evacuation drill, the evacuation drill operator is any one or more of the persons conducting the vehicle evacuation drill. The vehicle evacuation drill start input is an input used to initiate a vehicle evacuation drill at a vehicle. In embodiments, the vehicle evacuation drill start input is received at the controller 14 from any suitable HMI input device, such as from a mobile device (e.g., smartphone) that sends a wireless message (e.g., Wi-Fi™, Bluetooth™, cellular SMS). In other embodiments, the evacuation drill operator presses a pushbutton that is wired to the controller in a manner so that the controller detects depression of the pushbutton. The method 200 continues to step 220.
Steps 220-240 represent a fake evacuation drill detection mechanism or process 221 that is used to determine whether there are occupants present within the passenger cabin of the vehicle prior to beginning an evacuation phase of the evacuation drill.
In step 220, occupant detection sensors that detect occupants present within a passenger cabin of vehicle are activated. For example, in one embodiment, the controller 14 sends a sensor capture request to each of the occupant detection sensors 16 via the communications bus 30. According to other embodiments, other suitable form of communication between the controller 14 and the occupant detection sensors 16 may be used. The method 200 continues to step 230.
In step 230, it is determined whether occupants are present within the passenger cabin of the vehicle. The occupant detection sensors 16 provide a sensor capture result to the controller 14, indicating whether there was a positive detection or not—that is, whether an occupant was detected or not. The sensor capture result may be in any of a variety of forms when received from the occupant detection sensor 16; for example, the sensor capture result may include raw sensor measurements that are then interpreted at the controller 14; in other embodiments, the sensor capture result output by the occupant detection sensors 16 provides a clear indication with minimal to no processing being required as the sensor capture result itself directly indicates a positive or negative detection. When no occupants are detected, the method 200 continues to step 240; otherwise, the method 200 continues to step 250.
In step 240, an evacuation drill incomplete execution indicator is provided to an evacuation drill operator, such as the same evacuation drill operator that provided the vehicle evacuation drill start input. The evacuation drill incomplete execution indicator indicates to the evacuation drill operator that the vehicle evacuation drill was not performed or at least was not fully performed and so is therefore considered incomplete. According to embodiments, the any “indicator” discussed herein to be provided to a person may be provided using any suitable HMI output device, such as an audio speaker, graphics on a display (e.g., on the evacuation drill operator's smartphone), etc. The method 200 then ends, although one or more steps (or the entire method) may be repeated in order to attempt to complete a vehicle evacuation drill at the vehicle. Accordingly, the fake evacuation drill detection mechanism or process 221 enables verification that occupants are located within the vehicle (specifically, the passenger cabin) at or prior to the start of an evacuation phase of the evacuation drill.
In step 250, an evacuation phase of the vehicle evacuation drill begins and is monitored. This step 250 begins with step 252, wherein an evacuation countdown timer is initiated. The evacuation countdown timer defines a temporal extent of an evacuation phase of the evacuation drill in which one or more occupants are to evacuate a passenger cabin of the vehicle. The evacuation countdown timer may be predefined/predetermined, such as through setting the evacuation countdown timer to a fixed value, such as 5 or 10 minutes. In other embodiments, the evacuation drill operator may specify an amount of time for the evacuation countdown timer. The method 200 continues to step 254.
In step 254, it is determined whether occupants are present within the passenger cabin of the vehicle and, in step 256, it is determined whether occupants are present within the passenger cabin of the vehicle. These steps 254, 256 are analogous to steps 220 and 230, respectively, and the discussion of those steps 220, 230 is hereby incorporated and attributed to steps 254, 256 to the extent that discussion is not inconsistent with the express discussion of steps 254, 256. When no occupants are detected, the method 200 continues to step 258; otherwise, the method 200 continues to step 259.
In step 258, an evacuation drill unsuccessful execution indicator is provided to an evacuation drill operator, such as the same evacuation drill operator that provided the vehicle evacuation drill start input and/or other indicators. The evacuation drill unsuccessful execution indicator indicates to the evacuation drill operator that the vehicle evacuation drill was performed and resulted in an unsuccessful end result in that an occupant was detected at the end of an evacuation phase of a vehicle evacuation drill.
In step 259, an evacuation drill successful execution indicator is provided to an evacuation drill operator, such as the same evacuation drill operator that provided the vehicle evacuation drill start input and/or other indicators. The evacuation drill successful execution indicator indicates to the evacuation drill operator that the vehicle evacuation drill was performed and resulted in a successful end result in that no occupants were detected at the end of an evacuation phase of a vehicle evacuation drill.
The step 240 is analogous in operation to each of steps 258, 259, although the indicators and the information they indicate is different, and so that corresponding disclosure of the step 240 is hereby incorporated and attributed to each of steps 258, 259 to the extent that discussion is not inconsistent with the express discussion of steps 258, 259. The method 200 then ends, although one or more steps (or the entire method) may be repeated in order to attempt to carry out a successful vehicle evacuation drill (such as when the first iteration resulted in an evacuation drill unsuccessful execution indicator).
