USB Adapter Link for Multi-Seat Mobile Vehicle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems have limited flexibility in controlling vehicle functions using mobile terminals, as they primarily allow only information reception at the main driver's seat and charging or information transmission at other seats via Bluetooth, restricting the use of mobile terminals for vehicle control.
Innovation Solution
Implementing a vehicle control method using universal serial bus (USB) connections between mobile terminals, adapters, and cockpit domain controllers, allowing for the establishment of communication and control of vehicle functions such as air conditioning, window, seat, and ambient lamp adjustments through a universal serial bus protocol, with master and slave adapter interfaces for managing streaming media data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth connection is used for mobile terminal communication with vehicle, then wireless communication is enabled, but vehicle control functionality is limited and flexibility is reduced
Solution Approach 1:
The patent applies universality by enabling the USB adapter interface to serve multiple functions: it provides both charging capability and vehicle control functionality through a single physical interface. The adapter can handle different communication protocols and support various mobile terminal types, making the system more versatile without requiring separate dedicated interfaces for each function.
Solution Approach 2:
The USB adapter acts as an intermediary device between the mobile terminal and the vehicle's cockpit domain controller. It mediates the communication by receiving control instructions from the mobile terminal via USB connection and forwarding them to the vehicle system, thereby enabling enhanced vehicle control flexibility while maintaining system architecture integrity.
2Adaptability or versatility
If multiple adapter interfaces are provided for mobile terminal access, then more seats can control vehicle functions, but managing streaming media data transmission becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the adapter interfaces into master and slave roles. The master adapter interface handles streaming media data transmission and has priority access, while slave interfaces are restricted from transmitting streaming media but can still control vehicle functions. This segmentation resolves the complexity of managing multiple active transmission channels while enabling multi-seat control capability.
3Productivity
If USB protocol is used for vehicle control instructions, then communication efficiency is improved, but compatibility with existing Bluetooth systems may be reduced
Solution Approach 1:
The USB adapter serves as an intermediary that handles protocol conversion and instruction formatting. It receives control instructions from the mobile terminal using USB protocol and translates them into appropriate commands for the vehicle's existing control systems, thereby maintaining compatibility with legacy Bluetooth-based systems while utilizing the higher efficiency of USB communication.

AI summary
The invention relates to a vehicle control method and device, a vehicle, an adapter, a terminal and a medium in the technical field of vehicle engineering. In response to determining that a mobile terminal accesses the cockpit domain controller through the adapter interface, a universal serial communication connection between the mobile terminal and a terminal interface of an adapter and between a vehicle interface of the adapter and the adapter interface is established (S11); a vehicle control instruction forwarded by the adapter is received (S12), and the vehicle control instruction is generated by the mobile terminal in response to a user operation and transmitted to the adapter; and vehicle control corresponding to the vehicle control instruction is executed (S13) using the cockpit domain controller.
