Vehicle Body Controller Mode Change via Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems do not allow drivers to easily change the operation modes of body controllers, such as door, seat, and steering wheel modules, without visiting an auto repair shop, as these systems lack direct communication capabilities with the driver information system.
Innovation Solution
A control apparatus that includes a key input unit for selecting operation modes, a multimedia CAN communications unit for sending and receiving signals through a gateway, and a conversion unit to convert signals between multimedia CAN and body CAN networks, enabling users to change operation modes of body controllers like DDM, PSM, SCM, and IPM directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If body controllers use preset operation modes for controlling vehicle components, then the control functions are reliable and stable, but the ease of operation deteriorates because users cannot directly change modes through the driver information system
Solution Approach 1:
The patent introduces a gateway as an intermediary device that bridges the multimedia CAN network (driver information system) and the body CAN network (body controllers). The gateway includes a multimedia CAN communication unit, body CAN communication unit, and conversion unit that translates between different CAN protocols, enabling users to change operation modes through the driver information system without directly accessing body controller internals.
Solution Approach 2:
The gateway is designed with multi-functional capabilities to handle both multimedia CAN and body CAN communications simultaneously. It can receive operation mode selection signals from various body controllers (DDM, PSM, SCM, IPM), convert between different communication protocols, and manage multiple operation modes (automatic locking/unlocking, seat easy access, steering easy access, power supply blocking) through a single unified interface.
2Adaptability or versatility
If body controllers communicate through dedicated body CAN network, then the communication reliability is maintained, but the adaptability deteriorates because the driver information system cannot access and change operation modes
Solution Approach 1:
The gateway serves as a protocol translation intermediary between the multimedia CAN network and body CAN network. The conversion unit within the gateway translates messages between different CAN protocols, allowing the driver information system to send operation mode selection signals that are reliably delivered to the appropriate body controllers while maintaining the integrity of both communication networks.
Solution Approach 2:
The vehicle's communication system is segmented into two distinct networks: the multimedia CAN network for driver information and entertainment functions, and the body CAN network for vehicle control functions. The gateway provides controlled interaction between these segmented networks, allowing selective access to body controller operation modes while maintaining network independence and reliability.
3Ease of operation
If users want to change operation modes of body controllers, then the ease of operation improves, but the loss of time increases because users must visit auto repair shops
Solution Approach 1:
The system enables self-service operation mode changes by allowing drivers to directly select and change operation modes through the driver information system interface. The gateway automatically processes these selection signals, translates them to the appropriate body CAN protocol, and delivers them to the target body controllers, eliminating the need for professional repair shop intervention and saving users significant time.
Solution Approach 2:
The gateway implements a feedback mechanism where it receives operation mode selection signals from the driver information system, processes them through the conversion unit, sends them to the appropriate body controllers, and then receives confirmation signals back. This feedback loop ensures reliable mode changes while providing users with immediate confirmation that their selection was successfully processed, eliminating the need for external verification at repair shops.
