Remote Vehicle Startup Direct Communication Permission Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The center type remote startup system for vehicles is prone to failure when communication disruptions occur between the terminal, center server, and vehicle, preventing users from remotely operating the vehicle's driving devices.
Innovation Solution
Incorporating a direct communication permission unit in at least one of the center server, terminal, and vehicle to enable direct communication between the terminal and vehicle without passing through the center server, using communication standards like Bluetooth or Wi-Fi, and employing a communication availability determination unit to assess and permit direct communication when disruptions exceed a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct communication between terminal and vehicle is enabled, then reliability is improved, but device complexity increases
Solution Approach 1:
The communication system is segmented into two distinct paths: direct communication (terminal to vehicle) and indirect communication (terminal through center server to vehicle). This segmentation allows the system to switch between communication paths based on availability, improving reliability without requiring complete redesign of the entire system.
Solution Approach 2:
The system changes the communication parameter from single-path to multi-path by introducing direct communication as an alternative route. This parameter change enables the system to adapt to different communication conditions and maintain reliability when the center server path is unavailable.
2Ease of operation
If direct communication is always permitted, then ease of operation is improved, but security increases risk
Solution Approach 1:
The direct communication permission is made dynamic rather than static. The permission unit adjusts the communication mode based on real-time conditions, permitting direct communication only when the center server path is disrupted. This dynamic adjustment maintains ease of operation when needed while minimizing security risks by limiting direct communication to appropriate scenarios.
Solution Approach 2:
The center server acts as an intermediary that verifies and authorizes direct communication. Even when direct communication is permitted, the system maintains the center server's role in overseeing the communication flow, reducing security risks while enabling operational continuity.
3Reliability
If communication disruption detection is implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The permission unit implements feedback mechanisms to detect communication disruptions between the terminal and center server. By continuously monitoring communication status and receiving feedback about connectivity, the system can automatically switch to direct communication mode when disruptions are detected, improving reliability without requiring complex manual intervention.

AI summary
A remote startup system includes a terminal; a center server configured to communicate with the terminal and receive a startup request from the terminal; and a vehicle on which a driving device is mounted, the vehicle being configured to communicate with the center server, receive the startup request from the center server, and start up the driving device, wherein at least one of the center server, the terminal, and the vehicle includes a direct communication permission unit configured to permit direct communication in a case where the communication between the terminal and the center server or between the center server and the vehicle is disrupted, the direct communication being transmission or reception of information on the startup of the driving device based on the startup request, the direct communication being performed between the terminal and the vehicle directly without passing through the center server.
