Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for vehicles face usability degradation when communication is lost, as emergency stop information is always displayed clearly, potentially neglecting other safety checks.
Innovation Solution
A remote control apparatus that predicts an emergency stop position based on vehicle state information and adjusts the visibility of the stop position indicator based on communication reliability, ensuring safety while minimizing usability impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency stop position indicator is always displayed clearly on the display device, then the operator can be aware of safety information when communication is lost, but the usability of the remote control apparatus is degraded and other safety checks may be neglected
Solution Approach 1:
The patent applies dynamics by making the display characteristics of the emergency stop position indicator dynamically adjustable based on communication reliability. The control unit changes the display parameters (such as brightness, color, or visibility) of the indicator according to the calculated communication reliability between the vehicle and remote control apparatus. When communication is reliable, the indicator is displayed with lower prominence; when communication reliability decreases, the indicator becomes more prominent, thus adapting the safety information display to current operational conditions without permanently degrading usability
Solution Approach 2:
The patent implements parameter changes by modifying the display parameters of the emergency stop position indicator based on communication reliability thresholds. The control unit calculates communication reliability and adjusts display parameters (such as luminance, contrast, or visibility) accordingly. This allows the system to maintain high usability under normal conditions while ensuring safety information is prominently displayed when communication reliability deteriorates, effectively resolving the contradiction between safety and usability
2Reliability
If the emergency stop position indicator is displayed with high noticeability, then safety is ensured when communication is lost, but the operator may be excessively conscious of the indicator even when communication reliability is high
Solution Approach 1:
The system dynamically adjusts the noticeability of the emergency stop position indicator based on real-time communication reliability assessment. When communication reliability is high, the indicator is displayed with subdued characteristics to prevent operator distraction. When communication reliability drops below thresholds, the indicator automatically increases in noticeability, ensuring safety information is prominent only when needed, thus eliminating the harmful effect of constant operator awareness while maintaining safety assurance
3Ease of operation
If communication reliability is continuously monitored and display adjusted, then optimal balance between safety and usability is achieved, but the system complexity increases
Solution Approach 1:
The patent implements feedback by continuously monitoring communication reliability between the vehicle and remote control apparatus and using this information to adjust the display characteristics of the emergency stop position indicator. The control unit calculates communication reliability based on signal quality metrics and automatically modifies display parameters accordingly. This closed-loop feedback system optimizes the balance between safety and usability without requiring complex manual intervention, as the system self-adjusts based on real-time communication conditions

AI summary
The present disclosure proposes a technique regarding a remote control apparatus for remotely driving or assisting a vehicle by communicating with the vehicle. The remote control apparatus comprises a display device and one or more processors. The one or more processors is configured to execute acquiring an image captured by a vehicle camera and traveling state information of the vehicle, displaying the image on the display device, predicting a position where the vehicle emergently stops when communication with the vehicle is lost based on the traveling state information, and displaying an object indicating the predicted position on the display device to be superimposed on the image. The displaying the object on the display device includes calculating a reliability of the communication with the vehicle, and changing an appearance of the object such that noticeability of the object is lower as the reliability is higher.
