Trailer Camera Network for Vehicle Situational Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to effectively enhance driver situational awareness, particularly in critical maneuvers like lane changing, turning, and backing up, due to limited viewing areas and lack of real-time environmental data within and around the vehicle.
Innovation Solution
A system of strategically located sensory communication devices, including cameras and sensors, connected to a user network via an onboard access point, which activate upon triggering events to transmit real-time vehicle information, allowing drivers or remote users to access and analyze this data for improved situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple sensory communication devices are strategically located on the vehicle to expand viewing areas, then driver situational awareness is improved, but device complexity and energy consumption increase
Solution Approach 1:
The system divides the vehicle monitoring into multiple independent sensory communication devices positioned at different locations (front, rear, sides, interior). Each device independently captures data from its specific zone, and the onboard access point aggregates these segmented views into a comprehensive situational awareness system, resolving the contradiction by distributing complexity across modular components.
Solution Approach 2:
The sensory communication devices are designed to perform multiple functions: capturing video, audio, and environmental data; detecting triggering events; and transmitting information through a unified onboard access point. This multi-functionality reduces the need for separate specialized systems, improving situational awareness while controlling overall system complexity.
2Loss of information
If sensory communication devices are activated continuously to provide real-time data, then situational awareness is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous activation, the sensory communication devices operate periodically based on triggering events such as vehicle motion detection, door opening/closing, or manual activation. The onboard access point manages power states, activating devices only when needed and placing them in sleep mode otherwise, thereby maintaining real-time information availability when required while significantly reducing overall energy consumption.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors detect vehicle state changes (motion, door status, ignition state) and automatically trigger appropriate sensory communication devices. This event-driven feedback loop ensures real-time monitoring is activated only when the vehicle state warrants it, optimizing the balance between information availability and energy usage.
3Measurement precision
If multiple triggering events are monitored to activate specific devices, then operational precision is improved, but measurement and detection difficulty increases
Solution Approach 1:
Different triggering events are assigned to specific sensory communication devices based on their location and function. For example, motion sensors on the exterior trigger exterior cameras, while interior sensors trigger interior monitoring devices. This segmentation of detection responsibilities simplifies the complexity of monitoring multiple event types by distributing detection tasks across specialized components.
Data Source
AI summary
A method for enhancing situational awareness in a transportation vehicle including combination tractor and a trailer. The method includes locating a plurality of cameras on the trailer of the vehicle. Each camera is equipped with a camera wash system including a wash nozzle, dryer, and defroster. The cameras are operatively connected to a local area user network via an onboard access point. The onboard access point communicates with a data bus of the vehicle. At vehicle start-up, the cameras are automatically paired with a computing device located inside the tractor. The computing device includes a display screen and graphical interface with icon tabs representing each of the connected cameras. Using the icon tabs rendered on the display screen of the computing device, a selected camera and associated camera wash system can be manually activated.
