Solution Overview

Problem

Conventional automatic parking systems experience frequent switching of display screens during automatic parking, which can be inconvenient for users, especially when there are many obstacles, as they require frequent updates of the vehicle's surroundings, leading to discomfort and difficulty in grasping the relative positional relationship between the vehicle and obstacles.

Innovation Solution

An automatic parking assistance system that includes a traveling-direction display unit, a Bird's-Eye View (BEV) image display unit, a condition holding unit, and an area adjustment unit, which adjusts the display mode between BEV priority and traveling-direction priority modes based on obstacle and parking section proximity conditions to reduce screen switching frequency, ensuring timely and appropriate image display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the display screen frequently switches to show obstacle information when obstacles are detected, then the user can grasp the surrounding situation more accurately, but the switching frequency becomes too high causing inconvenience and discomfort

Engineering Contradiction:
Improvesurrounding situation informationVSAvoiddisplay stability
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display mode dynamically adjusts between BEV priority mode and traveling-direction priority mode based on real-time conditions (obstacle proximity, parking section proximity, and vehicle traveling direction). This dynamic adaptation allows the system to provide appropriate information at different stages of the parking process without excessive switching, resolving the contradiction between information completeness and display stability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes display parameters (which mode is prioritized) based on changing conditions during automatic parking. By monitoring obstacle proximity, parking section proximity, and vehicle traveling direction, the system adjusts the display mode to show relevant information only when necessary, reducing unnecessary switching while maintaining situational awareness.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the system displays detailed obstacle information during automatic parking, then the user can monitor the surroundings better, but the display switching becomes frequent and uncomfortable

Engineering Contradiction:
Improvesurroundings monitoringVSAvoiddisplay control complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The display control is segmented into distinct modes (BEV priority mode and traveling-direction priority mode), each serving specific functions. This segmentation simplifies the control logic by dividing the complex display management into manageable segments, where each mode has clear entry and exit conditions based on vehicle state and environmental factors.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically transitions between display modes based on real-time conditions. The display control complexity is managed by implementing dynamic switching rules that activate specific modes only when their corresponding conditions are met, avoiding the need for complex continuous adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If the display mode switches frequently to update obstacle positions, then the information remains current, but user comfort decreases due to excessive switching

Engineering Contradiction:
Improveobstacle position accuracyVSAvoiduser adaptation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system changes display parameters based on vehicle traveling direction and proximity conditions. By monitoring whether the vehicle is moving forward or backward, and the proximity to obstacles and parking sections, the system adjusts the display mode to show current obstacle positions without causing excessive switching that would require user adaptation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The display system uses feedback from vehicle sensors (traveling direction, proximity detectors) to determine when mode switching is appropriate. This feedback mechanism ensures that display updates occur only when necessary to maintain accurate obstacle position information, avoiding unnecessary switches that would disrupt user experience.

Inventive Principle:
Principle #23Feedback

AI summary

An automatic parking assistance system (10) includes a traveling-direction display unit (46), a BEV-image display unit (47), a condition holding unit (49), and an area adjustment unit (48). The traveling-direction display unit (46) is configured to display a traveling-direction image (31) in a traveling-direction display area (52) on a monitor (24) inside a vehicle (200). The BEV-image display unit (47) is configured to display a Bird's-Eye View image (32) in a BEV-display area (51) on the monitor (24). The condition holding unit (49) holds an obstacle proximity condition and a section proximity condition. The area adjustment unit (48) switches display on the monitor (24) between a BEV priority mode and a traveling-direction priority mode by adjusting size of each of the traveling-direction display area (52) and the BEV-display area (51). In the BEV priority mode, the BEV-display area (51) is wider than the traveling-direction display area (52). In the traveling-direction priority mode, the traveling-direction display area (52) is wider than the BEV-display area (51). The area adjustment unit (48) switches the display from the BEV priority mode to the traveling-direction priority mode when the obstacle proximity condition or the section proximity condition is satisfied.
