Teleoperation Vehicle Control System for Difficult Driving Situations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in handling difficult driving situations such as heavy traffic, incorrect navigation, and driver emotional states, leading to inefficient or undesirable operations.
Innovation Solution
A vehicle control system that includes sensors to capture real-time signals, switching to a teleoperation mode when necessary, and connects with a teleoperation server to select a suitable teleoperator based on location, time zone, and licensing, allowing remote control of the vehicle for safer and cost-effective operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous vehicle operates in autonomous mode, then automation level is improved, but reliability deteriorates in difficult driving situations
Solution Approach 1:
The patent introduces a teleoperation server as an intermediary between the autonomous vehicle and remote operators. When the autonomous vehicle encounters difficult situations (heavy traffic, incorrect navigation, driver emotional states), it automatically connects to the teleoperation server, which then connects to a human operator for remote assistance, thus maintaining high automation while ensuring reliability through human intervention when needed
Solution Approach 2:
The system dynamically switches between autonomous mode and teleoperation mode based on real-time assessment of driving conditions. The vehicle operates autonomously in normal conditions but transitions to teleoperation when difficulties are detected, creating a flexible system that adapts its automation level to match situation requirements
2Reliability
If teleoperation mode is activated, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complexity of teleoperation from the vehicle itself and places it in a separate teleoperation server. The vehicle only needs minimal components (sensors, communication module) to detect difficult situations and initiate connection, while the complex teleoperation infrastructure (operator matching, communication management) is handled by the external server, thus improving reliability without significantly increasing vehicle complexity
3Reliability
If teleoperation server selects operators based on multiple criteria, then service quality is improved, but processing time increases
Solution Approach 1:
The teleoperation server pre-establishes connections with multiple potential operators and maintains their availability status before being needed. When a vehicle requires teleoperation, the server can immediately connect to a pre-vetted operator who matches the required criteria (location, time zone, licensing), rather than searching for and vetting operators in real-time, thus ensuring quality selection without excessive delay

AI summary
A vehicle control system to provide driving assistance for a vehicle include a plurality of sensors and circuitry. The plurality of sensors captures one or more signals associated with the vehicle. The circuitry identifies a trigger input to change a current operation mode of the vehicle to a teleoperation mode of the vehicle. The circuitry further transmits, in the teleoperation mode, the captured one or more signals to a teleoperation server of a plurality of teleoperation servers. The circuitry further receives, in the teleoperation mode, one or more vehicular instructions from the teleoperation server based on the transmitted one or more signals. The circuitry further controls, in the teleoperation mode, at least one component of the vehicle based on the received one or more vehicular instructions to control movement of the vehicle.
