Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems require new electronic control devices to be installed or replaced in vehicles for additional control functions and lack precision in considering road and traffic conditions, limiting their ability to provide comprehensive and autonomous vehicle control.
Innovation Solution
A vehicle control system that utilizes an external electronic control unit, which communicates with sensors and actuators within the vehicle to receive and transmit control signals, enabling the application of new control functions and precise vehicle control through communication with a user's terminal, such as a smartphone or tablet, and includes a domain control unit to process sensor data and send control signals to actuators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If new electronic control devices are installed or replaced in vehicles for additional control functions, then vehicle control functionality is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent introduces an external electronic control unit as an intermediary device that communicates with the vehicle's existing electronic control devices through a communication interface. This external unit can provide additional control functions without requiring physical installation or replacement of devices inside the vehicle, thereby resolving the contradiction between functionality and complexity
Solution Approach 2:
The control system is divided into two segments: the vehicle's existing electronic control devices and an external electronic control unit. This segmentation allows the vehicle to gain additional control functions through the external unit while keeping the internal device structure simple and unchanged
2Measurement precision
If conventional electronic control devices are used for vehicle control, then device simplicity is maintained, but measurement precision and control accuracy deteriorate due to inability to comprehensively consider road and traffic conditions
Solution Approach 1:
The external electronic control unit acts as a mediator that receives and processes additional information about road and traffic conditions, then transmits processed control signals to the vehicle's existing devices. This intermediary approach enables higher measurement precision without requiring complete redesign of the internal control system
Solution Approach 2:
The external electronic control unit is designed to perform multiple functions: receiving vehicle information, processing additional environmental data, making control decisions, and communicating with various vehicle systems. This multi-functionality improves control precision while avoiding the need to add multiple separate devices
