Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote control systems for vehicles face safety concerns such as poor operator ergonomics, plausibility checks for operating steps, and potential misuse, which hinder their practical and series use due to unresolved safety aspects and regulatory approval issues.
Innovation Solution
A system comprising a vehicle and remote control with transceivers that enable signal exchange for initiating driving maneuvers, featuring position-based enabling/disabling of remote control, seat occupancy checks, and use of sensors like acceleration and position sensors for intuitive control, along with image data and collision monitoring to enhance safety and ergonomics, and integration with infrastructure information for precise navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control of vehicle is enabled for convenient parking and maneuvering, then ease of operation is improved, but safety risks increase due to potential misuse and lack of operator presence
Solution Approach 1:
The system performs preliminary safety checks before enabling remote control operation. It verifies that the vehicle is in a safe location (not on public roads), that no occupants are present, and that the environment is suitable for remote operation. These preliminary actions prevent unsafe remote control scenarios from occurring in the first place.
Solution Approach 2:
The system continuously monitors vehicle position, occupancy status, and environmental conditions during remote control operation. It provides feedback to the remote control device about the current safety status and can terminate remote control if unsafe conditions develop, ensuring ongoing safety throughout the operation.
2Reliability
If comprehensive safety checks and position verification are implemented, then safety is improved, but device complexity increases
Solution Approach 1:
The system uses multi-functional components that serve multiple purposes. For example, the position sensors not only determine location for remote control enabling but also support navigation and collision avoidance. The occupancy sensors serve both safety verification and operational control functions, reducing the need for separate dedicated components.
Solution Approach 2:
The patent combines multiple safety verification functions into a unified control system. Position verification, occupancy detection, and environmental assessment are integrated into a single remote control enablement decision process, managed by a central control unit that coordinates all safety checks and operational control in one system.
3Reliability
If seat occupancy checks are performed to ensure no occupants are present, then safety is improved, but ease of operation is reduced due to additional操作步骤
Solution Approach 1:
The system automatically performs occupancy detection and verification without requiring manual intervention from the user. The occupancy sensors continuously monitor the vehicle interior, and the control system automatically determines whether remote control can be enabled based on occupancy status, eliminating the need for users to manually check or report occupancy.
