Vehicle Cargo Height Calculation and Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles carrying large cargo, such as bicycles, risk collisions with height limit facilities like tunnels due to inadequate height calculations, as existing systems fail to accurately assess the total vehicle-cargo height and provide timely warnings or control measures.
Innovation Solution
A vehicle system equipped with an imaging device to capture cargo images, a display unit to show the cargo height, and a processor to calculate the total vehicle-cargo height, which outputs warnings and controls the vehicle to prevent collisions by decelerating or stopping when the total height exceeds the facility's height limit, and informs the driver if the vehicle can pass safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cargo is loaded on the roof of a vehicle, then the vehicle can carry large items such as bicycles or camping equipment, but the total height of the vehicle and cargo may exceed the height limit of facilities such as tunnels, causing collision risk
Solution Approach 1:
The system performs preliminary actions by calculating the total height of the vehicle and cargo before the vehicle reaches the height limit facility, and provides advance warning to the driver. This allows the driver to take preventive measures (such as removing cargo or choosing an alternative route) before the collision risk becomes actual, thus resolving the contradiction between cargo carrying capability and collision risk.
2Object-affected harmful factors
If the vehicle decelerates or stops to prevent collision with height limit facility, then collision risk is reduced, but the vehicle's travel time and productivity are reduced
Solution Approach 1:
The system implements feedback by continuously monitoring the vehicle's position relative to height limit facilities, calculating total height, and providing real-time warning messages to the driver. This feedback loop enables the driver to make informed decisions about whether to decelerate, stop, or continue, allowing collision prevention while minimizing unnecessary interruptions to travel efficiency.
3Reliability
If the system provides detailed cargo height calculation and warning functions, then collision prevention capability is improved, but the system complexity increases
Solution Approach 1:
The system applies self-service by utilizing the vehicle's existing imaging devices (such as rearview cameras) and display units (such as infotainment screens) to perform cargo height calculation and warning functions. By repurposing existing components rather than adding dedicated new hardware, the system achieves reliable collision prevention capability while minimizing the increase in system complexity.

AI summary
A vehicle and a method for controlling the vehicle are provided. In particular, the vehicle includes an imaging device that is configured to acquire an image of a cargo loaded onto the vehicle and a display unit that is configured to display the image of the cargo acquired by the imaging device. Additionally, a processor is then configured to calculate a height of the cargo when the cargo displayed on the display unit is selected, and calculate a total height that is a sum of the height of the cargo and a height of the vehicle. Accordingly, the processor determines whether the vehicle is capable of safely passing through a detected height limit facility without the risk of a potential collision with the cargo.
