For the purposes of presenting a brief and clear description of the present invention, a preferred embodiment will be discussed as used for a front-loading truck, specifically to detect individuals who are accidentally dumped into the hopper of the truck. However, other embodiments are contemplated, including different types of trucks, as well as any other suitable commercial or larger vehicle, in which such safety systems would be desirable.

Referring now to FIG. 1 there is shown a perspective view of an embodiment of the truck camera and safety system 10 (hereafter known as “system”). The system 10 generally includes a truck 11 having a lift arm mechanism 12 and a hopper 13, which is visible in FIG. 2. While a front-loading lift arm mechanism 12 is shown, the present system 10 may be utilized with any type of truck that includes any possible commercial vehicle. In the shown embodiment, at least one camera 21 is disposed within the hopper 13. The system 10 further includes exterior cameras for additional monitoring and safety. In the shown embodiment, the exterior cameras 21 include a rear camera 22 mounted to a rear end of the truck 11, a front camera 23 mounted to a front end of the truck 11, and a pair of side cameras 24, each side camera 24 mounted to a side of the truck 11.

All of the cameras 21, 22, 23, 24 are configured to record and display video via a vehicle control interface, which includes a dash monitor 25 disposed within the vehicle cabin. The cameras 24 are numbered and positioned such that a full 360 degree view of the surroundings of the truck 11 may be monitored by the operator. The cameras 24 may be positioned in such away that is advantageous to keeping them operating as intended. For example, the front camera 23 may be positioned under the upper cabin shroud, to prevent debris and trash from accidentally contacting and damaging the front camera 23. The remaining cameras 23 may include similar advantageous positioning that uses elements of the truck to shield the cameras 23. In other embodiments, the cameras 23 include additional shielding elements attached to their housings.

Referring now to FIG. 2, there is shown a top plan view of an embodiment of the truck camera and safety system 10. Further, the hopper cameras 21 are adapted to provide a view of the entire interior area of the hopper 13. The system 10 further includes temperature sensors 31 disposed within the hopper 13, which are configured to detect the temperature of items falling into the hopper 13 as the lift arms 12 dump a container into the hopper 13. In some embodiments, the temperature sensors 31 are independent sensors, while in other embodiments, the temperature sensors 31 are embedded within the hopper cameras 21, in that the hopper cameras 21 may be infrared cameras 21A. The front 23, rear 22, and side 24 cameras are shown in one position, but may occupy any desired position on the body of the truck.

The hopper cameras 21 and any separate temperature sensor modules 31 ideally will be located somewhere beneath the cab protector portion of the vehicle. In this way, the camera 23 is protected from damage as debris is dumped into the hopper 13. Preferably, the front camera 23 is positioned inside of the cab on the windshield. Additional shrouds and guards may be included to protect the cameras 21, 23 from snow, ice, and other cold weather hazards. In the shown embodiment, the hopper 13 includes at two cameras 23 adapted to provide a total image of the interior of the hopper 13 for the operator via the display screen of the vehicle control interface.

Referring now to FIG. 3, there is shown a diagram of the components of an embodiment of the truck camera and safety system 10. The exterior system components include all of the cameras 20, which includes the exterior cameras and hopper cameras 21, as well as any independent temperature sensors 31. Each camera 20, 21 and temperature sensor 31 includes an independent power supply in some embodiments, but may be hard wired to a single power supply in other embodiments, which may be the vehicle battery or a separate onboard power supply for the system 10. Further, each camera 20, 21 and sensor 31 may include a wireless transceiver 41 for communicating wirelessly with a control module's wireless transceiver 42 via a network such as a LAN, WLAN, Bluetooth connection, Wi-Fi connection, or any other suitable wireless communications protocols. Some embodiments may instead include all hard-wired connections between components of the system 10.

The control module is operably connected to the cameras 20 and the temperature sensors 31 via wired or wireless connections. Similarly, the control module is also operably connected to one or more vehicle systems via a vehicle control interface. The vehicle control interface is preferably a single control unit that is disposed within the cabin of the vehicle. The vehicle control interface includes a display screen 25 that displays status alerts, images from the exterior and hopper cameras 20, and other information. The vehicle control interface may further include a speaker 26 for emitting audible alarms, as well as input controls 28 such as buttons, touchscreens, keypads, or the like for controlling the system's operation. In some embodiments, the main control module is integrated within the housing of the vehicle control interface.

The control module further includes a processor 44, a non-transitory computer readable medium operatively connected to the processor, which may be a flash memory, hard disc, or any other suitable memory type, and a logic 46 stored in the non-transitory computer readable medium that, when executed by the processor 44, causes the system 10 to perform a method.

The method includes detecting, via the temperature sensors 31, a temperature within the hopper 13. If the temperature detected is above a predetermined threshold temperature, such that there is a likelihood a person is currently in the hopper 13, then the system 10 automatically deactivates the overall system 10. This will prevent injury from occurring to the individual in the hopper 13, and further prevent damage from occurring to the truck itself.

Other vehicle systems may be automatically controlled in order to increase the safety provided by the present system 10. For example, the truck camera and safety system 10 further includes an in-vehicle alarm, such that the system 10 activates the in-vehicle alarm, emitting a sound through the vehicle control interface speaker 26 if the temperature detected is above the predetermined threshold temperature. The system 10 may further be configured to operate the vehicle's own alarm 16, horn, or other sounding devices, in order to alert the operator and surrounding individuals of the detected danger. In other embodiments, the further deactivates the lift arm mechanism 12 if the temperature detected is above a predetermined threshold temperature. Likewise, the system 10 may further be configured to activate one or more vehicle lights if the temperature detected is above a predetermined threshold temperature. These additional alert methods ensure that the vehicle operator is notified when an individual accidentally falls within the hopper 13 or otherwise becomes dangerously close to the exterior of the vehicle.

In some embodiments, the control module further comprises an image recognition module, wherein the image recognition module is configured to scan recorded images from the exterior and hopper cameras 21, and automatically detect the presence of an individual within the hopper 13 or within the viewing area of the exterior cameras 20. This may further enhance the safety of the present system, by providing an additional mechanism for detecting when individuals are too close to the vehicle or if they are accidentally in the hopper 21. In this way, the present invention greatly enhances the safety of current trucks and other commercial vehicles, which will prevent individuals from being injured by the trucks and prevent the trucks themselves from becoming damaged.
