Vehicle Position Detection for Automated Door and Engine Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyless access methods for vehicles are cumbersome in certain situations, requiring manual intervention for tasks like starting or stopping the engine, locking/unlocking doors, and opening/closing compartments, which can be inefficient, especially during delivery operations.
Innovation Solution
A method that uses radio signals to detect the position and movement of a device, such as a smartphone or RFID chip, relative to the vehicle, allowing for automated triggering of actions like starting/stopping the engine, opening/closing doors, and locking/unlocking compartments based on predefined conditions, using a logic control unit and actuators to perform configurable actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual key interaction is used for vehicle operations, then control and security are maintained, but operation time and efficiency are reduced
Solution Approach 1:
The vehicle system automatically detects the portable device's position and movement relative to the vehicle, and autonomously triggers appropriate actions (locking, unlocking, opening compartments, starting engine) without requiring manual key interaction. The system serves itself by monitoring device position and executing predetermined actions based on automated detection.
Solution Approach 2:
The patent replaces manual mechanical key operations with an automated electronic detection and control system. Radio frequency signals are used to detect the portable device's position and movement, substituting the mechanical key insertion and turning actions with electronic field-based detection and automated actuator-driven operations.
2Ease of operation
If automated position detection is implemented, then operation convenience is improved, but device complexity increases
Solution Approach 1:
A portable device acts as an intermediary between the user and the vehicle system. The portable device carries identification data and communicates with the vehicle's detection system, mediating the interaction and enabling automated recognition and authentication without requiring complex direct integration between the user and vehicle control systems.
Solution Approach 2:
The vehicle control unit serves multiple functions: it detects the portable device's position, determines movement relative to the vehicle, authenticates the device, and triggers various actions (locking, unlocking, opening compartments, starting engine). This multi-functionality consolidates what could be separate complex systems into a single integrated control unit.
