Remote Guide Path Planning for Autonomous Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles often get into trouble when they encounter obstacles or cannot automatically plan a path due to traffic control, road construction, or other issues, leading to delays and increased labor costs when manual assistance is required.
Innovation Solution
A method and apparatus that allow autonomous vehicles to request a guide path from a monitoring platform, which displays a map, changes track points based on user input, determines a guide path, and transmits path information to the vehicle, enabling it to travel along the guide path, thus reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If assistant personnel are assigned to help the vehicle get out of trouble, then the vehicle can be helped to resolve path planning failures, but it causes delay in handling and increases labor costs
Solution Approach 1:
The patent uses virtual track points as a digital copy representation of the vehicle's path on the map. By manipulating these virtual track points remotely through a terminal device, the system can plan and adjust paths without requiring physical presence of assistant personnel at the vehicle location, thus resolving the contradiction between reliable path planning and handling delay
Solution Approach 2:
The patent introduces a terminal device as an intermediary between the vehicle and the operator. The terminal device receives path planning requests from the vehicle, displays the map with track points, and allows remote manipulation of track points to generate optimized paths. This intermediary enables asynchronous path planning, eliminating the need for immediate physical intervention and reducing handling delays
2Reliability
If assistant personnel are assigned to the vehicle, then the vehicle can be helped to get out of trouble, but it increases labor costs
Solution Approach 1:
The virtual track points serve as a digital interface that replaces the need for physical assistant personnel. The terminal device allows remote manipulation of these track points to generate paths, converting the need for physical human labor into automated digital processing, thereby significantly reducing labor costs while maintaining autonomous driving reliability
Solution Approach 2:
The system enables the vehicle to autonomously request path planning assistance through the terminal device when it encounters obstacles or planning failures. The vehicle initiates the process by sending its current state and receiving the optimized path, making the system self-servicing rather than requiring continuous human supervision, thus reducing labor costs

AI summary
The present disclosure provides a method and apparatus of determining a guide path, and a method and apparatus of controlling driving of a vehicle. The method of determining the guide path may be performed by a monitoring platform and includes: displaying a map for a predetermined range of a vehicle in response to receiving a guide request transmitted by the vehicle, wherein the map includes a plurality of first track points for the vehicle; changing a position of at least one of the plurality of first track points in the map in response to a target operation on the at least one first track point, so as to obtain a plurality of second track points; determining the guide path for the vehicle according to the plurality of second track points; and transmitting path information indicative of the guide path to the vehicle.
