Remote Vehicle Guidance for Complex Semi-Autonomous Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle guidance systems face challenges in handling complex situations such as intersections, hilltops, and crowded areas, where road routing is not visible to driving-environment sensors, leading to increased risk of errors and accidents during semi-automated control.
Innovation Solution
Implementing a method for remote control of motor vehicles, where request signals are sent to check if the vehicle can be remotely controlled or if the driver is ready to take over, generating and outputting control signals for semi-automated guidance, ensuring safe and efficient navigation through difficult areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the motor vehicle uses semi-automated guidance in complex situations (intersections, hilltops, crowded areas), then the vehicle can attempt to handle these scenarios autonomously, but the risk of errors and accidents increases due to limited sensor visibility
Solution Approach 1:
A remote control system acts as an intermediary between the vehicle and the driver/environment. When the vehicle encounters complex situations beyond its automated handling capability, the system establishes a communication link with a remote operator who can provide guidance or take control, thereby bridging the gap between automated limitations and safe operation
Solution Approach 2:
The system performs preliminary checks to determine whether the vehicle is ready for remote control or if the driver is prepared to take over before actually transferring control. This advance preparation ensures that control transitions occur only under safe conditions, preventing accidents during the handover process
2Productivity
If the system transfers remote guidance back to the motor vehicle or driver, then autonomous operation is restored, but control transitions may cause delays or safety issues if not properly managed
Solution Approach 1:
Before transferring control back to the vehicle or driver, the system performs preliminary readiness checks to ensure the vehicle is capable of autonomous operation or the driver is prepared to take control. This prevents unsafe transitions and ensures continuous safe operation
Solution Approach 2:
The system implements feedback mechanisms to monitor the vehicle's readiness status and driver preparedness level during control transfer. Based on this feedback, the system determines whether conditions are appropriate for transferring control back, creating a closed-loop safety mechanism

AI summary
A method for the at least semi-automated guidance of a motor vehicle. The method includes: receiving request signals, which represent a request from the motor vehicle that it is to be remotely controlled in order to guide the motor vehicle in an at least semi-automated manner; checking, in response to the receipt of the request signals, whether the request can be met; if so, generating remote control signals for the at least semi-automated remote control of a lateral and longitudinal guidance of the motor vehicle; and outputting the generated remote control signals in order to guide the motor vehicle in an at least semi-automated manner on the basis of the generated remote control signals.
