Remote Vehicle Support With Blind-Spot Speed Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In remote control systems for vehicles, blind spots can lead to increased operator burden due to frequent remote control requests and insufficient determination time, resulting in sudden deceleration and safety issues.
Innovation Solution
A remote support system that calculates a blind spot elimination position and generates a speed plan for autonomous vehicle travel to ensure deceleration at a predetermined allowable rate, reducing operator burden and maintaining safety by providing sufficient determination time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the area for remote control is set based on blind spots, then remote control requests are sent frequently, but the burden on the remote operator increases
Solution Approach 1:
The system calculates a blind spot elimination position in advance and generates a speed plan before the vehicle reaches the blind spot area. The vehicle is decelerated gradually along a predetermined route to reach this position, allowing the remote operator sufficient time to prepare and reduce the burden of frequent sudden remote control requests.
2Productivity
If remote control determination is based on actually detected information, then determination time for the remote operator is insufficient, but the burden on the remote operator increases
Solution Approach 1:
The system performs preliminary deceleration control to bring the vehicle to a controlled stop at the blind spot elimination position before the remote operator needs to make a determination. This advance action provides the operator with sufficient time to assess the situation and make a decision, reducing operational burden while maintaining efficient determination.
3Loss of time
If sudden deceleration control is applied to wait for remote control start, then the vehicle can wait for remote operator, but safety is reduced and traffic flow is disrupted
Solution Approach 1:
Instead of sudden deceleration, the system implements dynamic, gradual deceleration control that adjusts the vehicle's speed along a predetermined route to reach the blind spot elimination position smoothly. This dynamic approach maintains vehicle safety and minimizes disruption to traffic flow while still allowing the vehicle to wait for the remote operator in a controlled manner.

AI summary
At least one processor of a vehicle is configured to execute at least one program to: generate a speed plan for a first travel route from a blind spot elimination position to a position specified by a control standby condition, the speed plan specifying a speed of the vehicle for a position on the first travel route so as to meet a requirement that the vehicle be decelerated at a predetermined allowable deceleration or less for a predetermined time from the blind spot elimination position to satisfy the control standby condition; and instruct, for a second travel route from a current position of the vehicle to the blind spot elimination position, the vehicle to travel along the second travel route by autonomous driving so as to cause the vehicle to reach a speed specified by the speed plan at the blind spot elimination position.
