Vehicle Remote Control Position-Based Safety Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for vehicles lack effective mechanisms to prevent unintentional operation, which can lead to accidents when the remote control device is activated by someone other than the owner or is unintentionally pressed, potentially causing the vehicle to move unexpectedly.
Innovation Solution
A vehicle control method that includes a communication unit, a position acquiring unit, and a controller to determine the location of the remote control device and restrict vehicle operations based on its position, signal strength, and proximity, sending notifications or altering the vehicle's path to prevent accidental movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control function is enabled for convenient vehicle operation, then ease of operation is improved, but safety deteriorates due to unintentional activation by unauthorized persons or accidental button presses
Solution Approach 1:
The system continuously monitors the position of the remote control device relative to the vehicle and uses this feedback to dynamically enable or disable remote control functions. When the device is detected inside the vehicle or within a predetermined unsafe distance, the system provides feedback by restricting remote control operations, thereby preventing unintentional activation while allowing convenient operation when the device is in safe positions.
Solution Approach 2:
The patent introduces an intermediary safety mechanism that acts as a mediator between the remote control device and the vehicle's driving operations. This intermediary layer checks the position of the remote control device and determines whether to permit or restrict command transmission, thereby preventing harmful effects without eliminating the convenience of remote control operation.
2Adaptability or versatility
If remote control allows vehicle movement from any location, then adaptability is improved, but reliability deteriorates due to increased risk of accidents when device is lost or stolen
Solution Approach 1:
The system dynamically adjusts the permitted remote control range based on real-time position detection. Rather than using a fixed remote control range, the system adapts the operational parameters by monitoring whether the remote control device is inside or outside the vehicle, enabling flexible control that maintains reliability by restricting operations when the device is in unsafe locations while preserving adaptability when safe.
3Object-affected harmful factors
If position detection is implemented to prevent unauthorized control, then safety is improved, but device complexity increases due to additional position acquiring unit and processing requirements
Solution Approach 1:
The position acquiring unit serves multiple functions: it detects whether the remote control device is inside the vehicle, determines the device's position relative to the vehicle, and provides this information for both safety restrictions and operational enablement. This multi-functional approach implements comprehensive safety checks without requiring separate complex systems for each function, thereby limiting unauthorized control while managing device complexity.

Function Achieved in This Case
Enhances safety by preventing unintentional vehicle movements and reducing the risk of accidents by ensuring that remote control operations are only performed when the device is in the owner's possession or within a predetermined distance, thereby minimizing the risk of collisions.
Implementation Method 1
obtain a signal strength of the instruction signal delivered from the remote control device and received via a low-frequency antenna in order to determine the position of the remote control device

AI summary
A vehicle includes: a communication unit performing communication with a remote control device and receiving an instruction signal for remotely controlling a driving operation of the vehicle from the remote control device; a position acquiring unit detecting a position of the remote control device when the communication unit receives the instruction signal from the remote control device; and a controller restricting the remote control of the driving operation of the vehicle based on the detected position of the remote control device.
