Automatic Parking BEV Display Switching for Obstacle Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic parking systems require user intervention to switch between wide-range and narrow-range displays of surrounding images, which can lead to delayed or inappropriate display of obstacle and parking section proximity, potentially causing discomfort and safety issues during automatic parking.
Innovation Solution
An automatic parking assistance system that includes a BEV-image display unit and a condition holding unit, which automatically switches from a wide-range to a narrow-range Bird's-Eye View image display when obstacle or section proximity conditions are met, allowing timely and appropriate visualization of the vehicle's surroundings without user operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display mode is switched manually by user instruction, then the user can control the display, but the display switching is delayed and requires user intervention
Solution Approach 1:
The display control unit automatically switches between wide-range and narrow-range display modes based on proximity information from sensors, eliminating the need for manual user input. The system serves itself by using its own sensor data to control display behavior, resolving the contradiction between ease of operation and response time.
Solution Approach 2:
The system uses feedback from proximity sensors to automatically adjust display mode. When the sensor detects that the vehicle is close to an obstacle or parking section, the display control unit receives this feedback and automatically switches to narrow-range mode, eliminating delay and user intervention requirements.
2Area of stationary object
If the display shows wide-range view, then the user can see the overall surroundings, but the proximity of obstacles and parking sections is not emphasized
Solution Approach 1:
The display field of view dynamically changes based on vehicle proximity to obstacles or parking sections. The system transitions from wide-range display during normal conditions to narrow-range display when proximity is detected, allowing the display area to adapt to operational needs and prevent information loss.
Solution Approach 2:
The display system applies different display qualities to different situations: wide-range view for general surroundings and narrow-range view for critical proximity situations. This local differentiation ensures that obstacle proximity information is emphasized when needed while maintaining overall situational awareness.
3Loss of information
If the display switches to narrow-range view automatically, then obstacle proximity is emphasized, but the overall surrounding context is reduced
Solution Approach 1:
The display field of view dynamically adjusts between wide and narrow ranges based on real-time proximity conditions. This dynamic switching ensures that the narrow-range view is only used when necessary for obstacle proximity emphasis, while the overall surrounding context is maintained during normal operations.
Solution Approach 2:
The system periodically monitors proximity conditions and switches display modes accordingly. This periodic assessment ensures that the narrow-range view is activated only when obstacle proximity requires emphasis, maintaining the balance between detailed information and overall context.

AI summary
An automatic parking assistance system (10) includes a BEV-image display unit (47), and a condition holding unit (48). The BEV-image display unit (47) is configured to output a Bird'-Eye View image (32) in a predetermined area on a monitor (24). The BEV image (32) is an image that is obtained by imaging surroundings of the vehicle (200) including the vehicle (200) itself and depicts the surrounding as viewed from above. The condition holding unit (48) holds an obstacle proximity condition and a section proximity condition. The obstacle proximity condition defines that distance between the vehicle (200) and an obstacle (29) is shorter than predetermined first distance during the automatic parking. The section proximity condition defines that distance between the vehicle (200) and a parking section (38) of a parking position (36) scheduled at a time of the automatic parking is shorter than predetermined second distance. The BEV-image display unit (47) switches display in the predetermined area of the monitor (24) from wide-range display of a wide-BEV image (32a) to narrow-range display of a narrow-BEV image (32b) that is obtained by narrowing a field of view of the wide-BEV image (32a) and depicts enlarged surroundings of the vehicle (200) when the obstacle proximity condition or the section proximity condition is satisfied.
