Remote Vehicle Control Safety Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote vehicle control systems lack efficient safety checks, leading to potential risks during remote operation, as they do not ensure that safety conditions are met before generating and outputting control signals.
Innovation Solution
A method that involves receiving and checking safety condition signals prior to generating remote control signals for motor vehicle operation, ensuring that safety conditions such as communication integrity, latency, and system redundancy are satisfied before allowing remote control, and automatically switching to emergency modes if conditions are not met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If remote control signals are generated and outputted without checking safety conditions, then the productivity of remote control operation is improved, but the reliability of remote control safety deteriorates
Solution Approach 1:
The patent applies preliminary action by checking safety conditions before generating and outputting remote control signals. The control unit verifies that safety conditions are met prior to allowing remote control operation, preventing unsafe operations from occurring in the first place
Solution Approach 2:
The patent implements feedback by continuously monitoring safety conditions and using this information to control whether remote control signals are generated. The control unit receives safety condition signals and uses this feedback to dynamically enable or disable remote control functionality based on current safety status
2Reliability
If safety condition checks are implemented before remote control, then the reliability of remote control safety is improved, but the complexity of the control system increases
Solution Approach 1:
The control unit performs multiple functions: it generates remote control signals, monitors safety conditions, evaluates whether safety conditions are met, and controls signal output based on safety status. By consolidating these functions into a single control unit, the system achieves comprehensive safety management without proportionally increasing overall system complexity
Solution Approach 2:
The patent merges the safety monitoring function with the remote control signal generation function in the same control unit. This integration allows safety checks to be performed within the existing control architecture rather than adding separate independent safety systems

AI summary
A method for controlling a motor vehicle remotely. The method includes: receiving safety condition signals, which represent at least one safety condition that must be satisfied, so that the motor vehicle may be controlled remotely; checking if the at least one safety condition is satisfied; generating remote control signals for controlling the motor vehicle remotely, based on a result of the check as to whether the at least one safety condition is satisfied; and outputting the remote control signals generated. A device, a computer program and a machine-readable storage medium, are also described.
