Solution Overview

Problem

Existing vehicle remote control methods require precise input positions on a touch panel, leading to failures if the input position deviates, preventing the vehicle from executing predetermined functions.

Innovation Solution

The system detects the input position of a touch operation on a touch panel and dynamically adjusts the gesture determination area, allowing gestures to be input at arbitrary positions, ensuring vehicle functions can be executed regardless of input position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the input position of the gesture is preliminarily specified on the touch panel, then the gesture recognition accuracy is improved, but the ease of operation deteriorates because the user must precisely input at the specified position

Engineering Contradiction:
Improvegesture recognition accuracyVSAvoidease of gesture input
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The gesture determination area is made variable rather than fixed. The area dynamically adjusts its position and size based on the detected touch input position, allowing the system to accommodate user input at any location on the touch panel while maintaining accurate gesture recognition

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The parameters of the gesture determination area (position and size) are changed based on the input position. When a touch is detected, the system calculates a new gesture determination area centered at or near the input position, thereby adapting the recognition parameters to the user's actual input location

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If a fixed gesture determination area is used, then the device complexity is reduced, but the adaptability deteriorates because gestures cannot be recognized at arbitrary positions

Engineering Contradiction:
Improvegesture control system complexityVSAvoidgesture input position flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The system implements a dynamic gesture determination area that automatically adjusts its parameters based on the touch input position, providing adaptability without requiring complex manual configuration or multiple predefined areas

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The variable gesture determination area serves multiple functions: it enables gesture recognition at any position on the touch panel, adapts to different gesture sizes, and maintains consistent recognition accuracy across the entire touch panel surface

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A vehicle remote control method is provided, which controls a vehicle (V) having an autonomous travel control function to execute autonomous travel control. The method includes detecting an input position at which a touch operation is performed by an operator (U) on a touch panel (211) of a remote operation device (21) and making a gesture determination area (Gal) variable in accordance with the input position. The gesture determination area (Gal) is an area in which a gesture (G4b) for remotely controlling the vehicle (V) is received. The method further includes detecting the gesture (G4b) from the gesture determination area (Gal) and determining whether or not the detected gesture (G4b) is a command gesture (G4) that is preliminarily set. When the gesture (G4b) is the command gesture (G4), the vehicle (V) is controlled to execute the autonomous travel control.
