USB Adapter Vehicle Control Across Seats via Cockpit Domain Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems lack flexibility in controlling vehicle functions from mobile terminals, as they can only receive information from the main driver's seat and other seats can only charge or receive information via Bluetooth, limiting the ability to control vehicle features like windows, air conditioning, and passenger seats from other seats.
Innovation Solution
Implementing a vehicle control method using a universal serial bus (USB) connection between a mobile terminal, an adapter, and a cockpit domain controller, allowing for universal serial communication and direct transmission of vehicle control instructions without protocol conversion, enabling control of various vehicle functions from any seat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth connection is used for mobile terminal access, then wireless communication is enabled, but control capability is limited to information reception only
Solution Approach 1:
The patent introduces a USB adapter as an intermediary device that connects the mobile terminal to the vehicle's USB interface. This adapter enables the mobile terminal to send control instructions to the vehicle system, transforming the limited Bluetooth information-reception mode into a full control capability mode where windows, air conditioning, and seat functions can be controlled from any seat.
2Adaptability or versatility
If USB connection is implemented across all seats, then control flexibility is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by using the existing USB interface standard across all vehicle seats. Instead of implementing complex wireless control systems or dedicated control interfaces for each seat, the solution leverages the universal USB connection standard that mobile terminals already possess, allowing any seat to control vehicle functions through a simple USB plug-and-play connection.
3Adaptability or versatility
If protocol conversion is required for communication, then compatibility is improved, but communication efficiency decreases
Solution Approach 1:
The patent achieves homogeneity by using the same USB communication protocol throughout the entire communication chain - from the mobile terminal's USB interface, through the USB adapter, to the vehicle's USB-connected control units. This eliminates the need for protocol conversion between different communication standards, thereby maintaining high communication efficiency while ensuring compatibility across all components.

AI summary
A vehicle control method, an adapter interface, apparatus and computer readable medium for improving in vehicle connectivity. The in-vehicle connectivity is improved by: in response to determining that a mobile terminal accesses the cockpit domain controller through the adapter interface, 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; a vehicle control instruction forwarded by the adapter is received, 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 using the cockpit domain controller.
