Mobile Device Vehicle Control via Telecommunications Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote vehicle control systems are limited by a small activation radius and are typically integrated with the key chain, failing to address issues like lost or locked keys.
Innovation Solution
A system utilizing a mobile communication device to initiate vehicle functions through a telecommunications network, including a recognition module, authentication module, query module, and communication module, which allows locking, unlocking, and starting vehicles via command signals, using mobile identification numbers and vehicle identification numbers stored in a subscriber database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key fob is used for remote vehicle control, then vehicle functions can be controlled remotely, but the control radius is limited and keys can be lost or locked inside the vehicle
Solution Approach 1:
The patent introduces a mobile communication network as an intermediary between the user and the vehicle. Instead of direct short-range communication between key fob and vehicle, the system uses cellular networks to relay commands, enabling remote control from any location with network coverage rather than being limited to proximity of the vehicle.
Solution Approach 2:
The system creates a functional copy of the key fob capability within the mobile communication network. The mobile phone acts as a virtual key, replicating the authentication and control functions of a physical key fob but with extended range through network infrastructure.
2Adaptability or versatility
If a mobile communication device is used to control vehicles remotely, then control radius is extended, but system complexity increases
Solution Approach 1:
The patent leverages the universal mobile communication network infrastructure already in place for voice and data services. By making the network multi-functional to also support vehicle control, the system avoids building dedicated infrastructure, thus managing complexity while achieving extended control radius.
Solution Approach 2:
The system uses existing mobile devices that users already carry and are familiar with. The mobile phone's existing capabilities (communication, authentication) are utilized for vehicle control, eliminating the need for users to learn new devices or procedures, thereby managing operational complexity.
3Reliability
If authentication is implemented to secure vehicle control, then security is improved, but operation time increases
Solution Approach 1:
The system performs authentication in advance by pre-registering mobile devices and vehicles in a database, establishing trusted relationships before control is needed. This preliminary setup enables faster subsequent authentication, reducing the time penalty during actual vehicle control operations.
Solution Approach 2:
The system implements efficient feedback mechanisms where the vehicle and mobile device can quickly verify each other's identity through pre-established authentication credentials. The feedback loop is optimized to confirm legitimacy rapidly, minimizing the time users perceive during the authentication process.
Data Source
AI summary
A method and system for implementing vehicle functions through a mobile device are provided. More particularly, a technique is implemented for initiating selected vehicle functions through a remote mobile device such as a mobile phone, rather that through a key fob. The system includes network functionality contained within the primary switching element of the network, e.g., a mobile switching center (MSC), to receive an access code (such as *89) from a user. The switching element subsequently transmits command signal(s) via a base station to a vehicle to perform vehicle functions such as locking, unlocking and starting.
