Vehicle Control System Distance Monitoring and Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems for remote automatic moving, such as remote parking, require users to be within a prescribed distance to monitor the vehicle, but fail to alert users when they exceed this distance, potentially leading to unawareness of vehicle stops and decreased attention to surroundings.
Innovation Solution
A vehicle control system that includes a control device on the vehicle and an operation terminal carried by the user, using position determination units to measure distance and issue warnings when the user is beyond a threshold, allowing the vehicle to stop and alert the user, while enabling continued monitoring of surroundings without constant attention to vehicle warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle stops when the user exceeds the prescribed distance, then user safety is improved, but the user may not recognize the reason for stopping
Solution Approach 1:
The system implements feedback by transmitting information to the operation terminal when the distance exceeds the threshold, notifying the user of the stopping reason. This closed-loop feedback ensures the user understands why the vehicle stopped, maintaining both safety and user awareness.
2Reliability
If the vehicle requires continuous user monitoring, then safety is improved, but the user cannot pay attention to surroundings
Solution Approach 1:
The system enables self-service by allowing the vehicle to autonomously monitor its own operation status and independently determine when to stop based on distance thresholds. This reduces the need for continuous user attention while maintaining safety through automated self-monitoring capabilities.
Solution Approach 2:
The system uses feedback to notify the user only when necessary (when distance exceeds threshold), rather than requiring continuous monitoring. This selective feedback approach maintains safety while freeing the user to attend to surroundings during normal operation.
3Loss of information
If the vehicle issues continuous warnings, then user awareness is improved, but the user becomes distracted from surroundings
Solution Approach 1:
The system applies periodic action by issuing warnings only at specific moments when the distance threshold is exceeded, rather than continuously. This intermittent warning approach maintains user awareness of distance constraints while minimizing distraction from surroundings during normal operation.
Solution Approach 2:
The feedback mechanism is designed to activate only when the distance exceeds the threshold, providing information on demand rather than continuously. This conditional feedback maintains awareness without creating constant distraction.

AI summary
A vehicle control system includes: a control device mounted on a vehicle and configured to execute remote automatic moving processing; an operation terminal configured to be carried by a user and to transmit a control signal to the control device based on an input by the user; and a position determination unit mounted on the vehicle and/or the operation terminal and configured to measure a distance between the operation terminal and the vehicle. When the control device determines that the distance exceeds a first threshold based on a signal from the position determination unit, the control device stops the vehicle and transmits an output signal to the operation terminal, the output signal being a signal to cause the operation terminal to output a fact that the distance exceeds the first threshold.
