Solution Overview

Problem

Existing vehicle information display devices struggle to clearly differentiate and emphasize the object of attention when multiple objects are present in the surrounding area, leading to confusion and potential interference between object marks and other objects, making it difficult for drivers to recognize the intended object.

Innovation Solution

A vehicle information display device and method that dynamically adjust the emphasis of the vertical component of the object mark based on the number of surrounding objects, suppressing the emphasis when multiple objects are detected to prevent interference and ensure clear recognition of the primary object, while maintaining emphasis when few or no objects are present.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a frame-like object mark with vertical direction components is displayed to emphasize the object, then the correspondence between the object mark and the object is strengthened, but when multiple objects exist in the lateral direction, the vertical direction component blurs and interferes with other objects, making it difficult to recognize which object the mark refers to

Engineering Contradiction:
Improvecorrespondence between object mark and objectVSAvoidinterference between object mark and other objects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by making the vertical direction components of the object mark selectively visible or invisible based on the detection result. When multiple objects are detected in the lateral direction, the vertical components are made invisible to prevent interference, while when few objects are detected, the vertical components are visible to strengthen correspondence. This local modification of display quality resolves the contradiction between strengthening correspondence and preventing interference.

Inventive Principle:
Principle #3Local quality

2Measurement precision

If the vertical direction component of the object mark is displayed to strengthen emphasis, then the object recognition is improved, but the focus position deviates in the lateral direction causing the vertical component to blur

Engineering Contradiction:
Improveobject recognition accuracyVSAvoidfocus position accuracy
Core Design Contradiction:
Measurement precisionVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by dynamically adjusting the visibility of the vertical direction components based on the number of detected objects. The display system transitions between static states (vertical components visible or invisible) according to real-time detection results, optimizing both recognition accuracy and focus position precision for different operational conditions.

AI summary

A vehicle information display device (1) including: a subject detecting sensor (10), that detects an object (A) positioned in a surrounding area of the vehicle and an object (B) different from the object (A); a display portion (40), that has a display area (31) that displays an object mark corresponded to the object (A) to emphatically display the object (A) detected by the subject detecting sensor (10), and displays the second object mark so that when a number of objects (B) that are in the vicinity of the detected object (A) and are detected by the subject detecting sensor (10) is large, the emphasizing degree of the vertical component of the second object mark is suppressed in comparison with the emphasizing degree of the vertical component of the first object mark when the number of objects (B) is small or no object (B) is detected.
