Around-View Display Boundary Control for Undistorted Parking Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems struggle to accurately display the vehicle's surroundings without distortion during parking, particularly when obstacles are present, as they fail to effectively combine and adjust camera and ultrasound sensor data to provide a clear, undistorted view of the environment.
Innovation Solution
A driver assistance apparatus equipped with multiple cameras and ultrasound sensors that combine image and detection data to generate around-view data, adjusting the display boundaries based on obstacle location and vehicle conditions, such as speed and door opening, to ensure accurate and undistorted visualization of the surroundings.

Engineering Contradiction Analysis
1Loss of information
If camera image data is combined to display around-view data during parking, then the driver can see the vehicle surroundings, but the display shows distortion of surrounding obstacles
Solution Approach 1:
The system dynamically changes the boundary angle parameters of the around-view display based on vehicle conditions (door opening state, driving speed). When the door is opened or speed exceeds a threshold, the boundary angle is adjusted from a first reference angle to a second reference angle, which compensates for the distortion caused by camera combination and provides an accurate representation of obstacle shapes and positions.
2Ease of operation
If the boundary angle is fixed at a first reference angle, then the around-view display is simple, but the obstacle shape becomes distorted when door opens or vehicle moves
Solution Approach 1:
The boundary angle of the around-view display is made dynamic rather than fixed. The system automatically adjusts the boundary angle from a first reference angle to a second reference angle based on real-time vehicle conditions such as door opening state and driving speed. This dynamic adjustment ensures reliable and accurate obstacle position display while maintaining system simplicity through automated control.
3Device complexity
If the around-view display uses a fixed boundary angle, then the display configuration is simple, but it cannot adapt to different driving conditions such as door opening or speed changes
Solution Approach 1:
The display configuration adapts dynamically to different driving conditions through automated boundary angle adjustment. When the door opening detector detects door opening or the speed detector detects speed exceeding a threshold, the system automatically changes the boundary angle from the first reference angle to the second reference angle, enabling the display to adapt to various driving scenarios without increasing operational complexity.
Solution Approach 2:
The system uses feedback from door opening detectors and speed detectors to automatically adjust the around-view display boundary angle. The detectors provide real-time information about vehicle conditions, and the control unit uses this feedback to switch between different reference angles, ensuring the display remains accurate and adaptable across different driving conditions.

AI summary
A vehicle includes a first camera mounted on the vehicle to have a first field of view facing a front or rear of the vehicle and configured to acquire first image data, a second camera mounted on the vehicle to have a second field of view facing a left or right side of the vehicle and configured to acquire second image data, and a display. The vehicle also has a controller configured to display first around-view data in which the first image data and the second image data are combined so that a boundary between the first image data and the second image data becomes a first reference angle on the display. The controller is also configured to combine the first image data and the second image data so that an angle between the boundary and a driving direction of the vehicle becomes a second reference angle greater than the first reference angle based on an opening of a door or trunk lid or gate of the vehicle.
