Vehicle Underside Height Detection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle object detection systems fail to accurately determine the height of objects relative to the underside sections of vehicles, leading to potential scratches or contact during maneuvers like parking and backing up, as conventional cameras provide misleading visual cues about object height.
Innovation Solution
A vehicle object detection system comprising a vehicle body structure, sensing devices, and a controller that processes data from cameras and sensors to display the height of detected objects relative to the underside sections, providing visual and audible warnings to prevent contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cameras are angled downward to provide visual contact confirmation, then object contact detection is improved, but object height measurement accuracy deteriorates
Solution Approach 1:
The system transitions from 2D camera images to 3D spatial understanding by using multiple sensors (cameras, LIDAR, ultrasonic sensors) to capture depth and distance information. The controller processes data from multiple angles and dimensions to calculate accurate object height relative to the vehicle underside, resolving the contradiction between contact detection and height measurement precision.
Solution Approach 2:
The controller acts as an intermediary that receives raw data from multiple sensing devices and transforms it into meaningful height information. By using LIDAR for precise distance measurement and ultrasonic sensors for proximity detection, the system mediates between the camera's visual contact confirmation and the need for accurate height data, combining multiple measurement approaches to achieve both goals.
2Productivity
If vehicles with low clearance are used, then maneuverability and parking efficiency are improved, but risk of contact damage with objects increases
Solution Approach 1:
The system performs preliminary detection of objects in the vehicle's path using multiple sensors before contact occurs. The controller continuously monitors the environment and provides early warning to the operator about potential contact risks, allowing the driver to take preventive action before damage occurs, thus enabling low-clearance vehicles to operate safely in tight spaces.
Solution Approach 2:
The system provides continuous feedback to the operator through visual and audible warnings about detected objects and potential contact risks. This real-time feedback loop allows the driver to adjust maneuvers to avoid contact, enabling efficient use of low-clearance vehicles without increasing damage risk.
3Measurement precision
If multiple sensing devices are added to detect object height, then measurement accuracy is improved, but system complexity increases
Solution Approach 1:
The system uses multi-functional sensing devices that can perform multiple detection tasks. For example, cameras provide both visual contact confirmation and spatial positioning information, while LIDAR provides both distance measurement and object轮廓 detection. The controller integrates data from these devices to achieve accurate height measurement without requiring separate dedicated sensors for each function, thus reducing overall system complexity.
Solution Approach 2:
The system merges multiple sensing functions into an integrated detection platform. The controller combines data from cameras, LIDAR, and ultrasonic sensors into a unified object model, achieving accurate height and distance measurement through data fusion rather than through separate independent systems, thereby reducing complexity while maintaining high measurement precision.

AI summary
A vehicle object detection system includes a vehicle body structure, a sensing device, a video display and a controller. The vehicle body structure defines a passenger compartment and has an underside section a predetermined height above ground. The sensing device detects height of an object within a prescribed area adjacent to the underside section as the vehicle body structure approaches the object. The video display is viewable from within the passenger compartment and displays images representing the prescribed area adjacent to the underside section of the vehicle body structure. The controller is configured to process object information received from the sensing device in order to determine the height of the object, and display images on the video display representing the object along with a representation of the height of the object relative to the underside section and images representing the underside section of the vehicle.
