Autonomous Vehicle Remote Instruction With Trajectory-Based Sensor Limiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle remote instruction systems for autonomous driving vehicles transmit unnecessary sensor information, increasing data capacity and requiring efficient methods to reduce this while ensuring accurate remote instructions based on external situations.
Innovation Solution
A vehicle remote instruction system that uses a transmission information limitation unit to set a limited information range for sensor data transmission based on the external environment and trajectory of the autonomous driving vehicle, selecting only necessary sensor information and adjusting sensor detection areas as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all sensor information is transmitted to the remote commander, then the remote commander can issue accurate remote instructions, but the data capacity increases
Solution Approach 1:
The transmission information limitation unit extracts and transmits only the necessary sensor information related to the external situation (such as objects in the detection area, trajectory, and environmental conditions) while excluding unnecessary sensor data. This extraction approach ensures that the remote commander receives sufficient information to issue accurate remote instructions without being overwhelmed by excessive data capacity.
2Area of stationary object
If sensor detection area is expanded to cover all external situations, then complete external environment is monitored, but data transmission burden increases
Solution Approach 1:
The system adjusts the sensor detection area dynamically based on the specific external situation and trajectory of the autonomous driving vehicle. Instead of maintaining a fixed large detection area, the sensor focuses on locally relevant regions that are important for the current situation, thereby monitoring necessary external environments while reducing the overall data transmission burden.
3Productivity
If transmission information limitation is applied to reduce data capacity, then data transmission efficiency improves, but information completeness may be compromised
Solution Approach 1:
The transmission information limitation unit preliminarily determines and transmits information about the external situation (including detected objects, trajectory, and environmental conditions) before the remote commander needs to issue instructions. This preliminary transmission of relevant information ensures that when the remote commander receives the data, the information is already complete and organized for making accurate remote instruction decisions, thus maintaining information completeness while improving transmission efficiency.

AI summary
In a vehicle remote instruction system, a remote commander issues a remote instruction relating to travel of an autonomous driving vehicle based on sensor information from an external sensor that detects an external environment of the autonomous driving vehicle. The vehicle remote instruction system sets a range of information to be transmitted to the remote commander among the sensor information detected by the external sensor, as a limited information range, based on the external situation or an external situation obtained based on map information and a trajectory of the autonomous driving vehicle.
