Solution Overview
Problem
Existing remote support systems for vehicles lack effective visualization of the vehicle's outer trajectory during turning, which hinders the remote driver's ability to accurately support vehicle travel, especially under low image resolution and high communication delay conditions.
Innovation Solution
A remote support apparatus that wirelessly communicates with the vehicle to acquire and display images, including a set steering angle line indicating the vehicle's predicted outer movement during turning, with adjustable visibility based on image resolution and communication delay, and automatic vehicle stopping functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remote support apparatus displays the set steering angle line to help recognize future travelling of the outer portion of the vehicle during turning, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The display information is segmented into different types (set steering angle line, predicted stop position, communication status indicators). Each segment serves a specific function, allowing the remote driver to process information hierarchically and improving ease of operation without overwhelming the system complexity
Solution Approach 2:
The set steering angle line shows the predicted future trajectory of the vehicle outer portion before the actual turning occurs. This preliminary visualization allows the remote driver to anticipate and plan steering actions, improving operational ease by providing advance information about vehicle behavior
2Measurement precision
If the set steering angle is set to a small angle when image resolution is low to ensure accurate trajectory representation, then the measurement precision is improved, but the loss of information increases
Solution Approach 1:
The system dynamically changes the set steering angle parameter based on image resolution quality. When resolution is low, a smaller steering angle is selected to ensure the predicted trajectory remains within the visible image area, maintaining measurement precision. When resolution is high, larger steering angles can be displayed, reducing information loss about the full vehicle trajectory
Solution Approach 2:
When image resolution is low, the system displays only a partial trajectory (smaller steering angle) that is guaranteed to be visible, rather than attempting to show the complete trajectory which would extend beyond the image boundaries. This partial action maintains precision for the visible portion while accepting limited information about the full trajectory
3Reliability
If the set steering angle is adjusted based on communication delay to maintain accurate trajectory prediction, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The system continuously monitors communication delay between the vehicle and remote support apparatus, and uses this feedback to dynamically adjust the set steering angle. When delay is high, a smaller angle ensures the predicted trajectory remains accurate for the delayed image data. This feedback mechanism improves reliability by adapting to real-time communication conditions
Solution Approach 2:
The set steering angle is not fixed but dynamically adjusted based on communication delay conditions. The system transitions between different steering angle values depending on the current communication state, making the trajectory prediction adaptive and reliable under varying network conditions without requiring complex real-time recalculation
4Loss of information
If the remote support apparatus provides comprehensive trajectory information including set steering angle line, then the loss of information is reduced, but the device complexity increases
Solution Approach 1:
The system merges multiple pieces of trajectory information (set steering angle line, predicted stop position, current vehicle position) into a single integrated display. This combination provides comprehensive trajectory information that reduces loss of information about vehicle behavior, while the unified display approach avoids the complexity of separate display systems for each information type

AI summary
A remote support apparatus remotely supports a travelling of a vehicle. The remote support apparatus communicates wirelessly with the vehicle. The remote support apparatus wirelessly acquires an image of a view in a travelling direction of the vehicle and display the acquired image by a displaying device of the remote support apparatus. The image is taken by an imaging device of the vehicle. The remote support apparatus displays a set steering angle line in the image displayed by the displaying device. The set steering angle line is a line along which an outer portion of the vehicle during vehicle turning is predicted to move when the vehicle turns at a set steering angle.
