Refuse Vehicle Camera View Prioritization Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refuse vehicle systems lack an efficient method to prioritize and display camera views, particularly during reverse operations, leading to potential obstacles being missed due to inconsistent or moving camera views.
Innovation Solution
A refuse vehicle system equipped with multiple cameras and a controller that assigns priority values to different camera views based on operating conditions, such as reverse operations, and automatically selects and displays the most relevant views to the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple cameras are installed to capture different views, then the coverage of monitoring area is improved, but the complexity of view selection and display management increases
Solution Approach 1:
The system segments the monitoring area into multiple zones (hopper area, lift assembly area, rear area) and assigns dedicated cameras to each zone. This segmentation allows the controller to selectively activate and display only the relevant camera views based on current operational needs, rather than managing all camera feeds simultaneously, thus reducing display management complexity while maintaining comprehensive coverage.
Solution Approach 2:
The system dynamically adjusts which camera views are displayed based on real-time operational conditions. The controller automatically switches between different camera feeds (hopper camera, lift assembly camera, rear camera) depending on the vehicle's operational state, such as whether the lift assembly is raised or lowered, ensuring the operator always sees the most relevant view without manual intervention.
2Loss of information
If camera views are switched frequently to show different areas, then the information completeness is improved, but the operator's ability to focus on critical areas is reduced
Solution Approach 1:
The system uses feedback from sensors detecting the lift assembly position and vehicle operational state to automatically determine which camera view should be displayed. When the lift assembly is raised, the system switches to the hopper camera view; when lowered, it switches to the lift assembly camera view. This feedback-driven automatic switching ensures information completeness about critical areas without requiring frequent manual view changes that would disrupt operator focus.
Solution Approach 2:
The camera selection system operates autonomously, self-managing the switching between different camera views based on pre-programmed criteria related to vehicle operation. The controller automatically selects and displays the appropriate camera feed without operator input, allowing the operator to maintain focus on the primary task while the system handles view management independently.
3Loss of information
If the camera system displays all available views simultaneously, then the information completeness is improved, but the display interface complexity and space requirements increase
Solution Approach 1:
The system extracts and displays only the essential camera view relevant to current operations, rather than showing all available views simultaneously. Based on the operational state (lift assembly position, vehicle movement), the controller selectively extracts and presents the most critical camera feed to the operator, maintaining information completeness about safety-critical areas while simplifying the display interface to show only one primary view at a time.

AI summary
A refuse vehicle includes a chassis, a body coupled to the chassis and defining a refuse compartment, a lift assembly configured to lift a refuse container to dump contents thereof into the refuse compartment, a display interface, a plurality of cameras positioned to capture a plurality of different views from the refuse vehicle, and a controller. The controller is configured to assign priority values to the plurality of different views, compare the priority values, and display, on the display interface, at least one of the plurality of different views based on the comparison of the priority values.
