Solution Overview
Problem
Existing road-to-vehicle wireless communication systems face challenges in enabling prompt external control of vehicles, particularly in scenarios requiring urgent action such as accident prevention or stolen vehicle recovery, due to delays and complexities in data transmission and interpretation.
Innovation Solution
An in-vehicle wireless communication apparatus that includes a wireless communication unit for communicating with out-of-vehicle apparatuses and a processing unit that transmits and receives control data, allowing direct output to the vehicle's network without intermediate interpretation, enabling rapid external control by transmitting data in a predefined format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control data is transmitted through multiple processing stages with interpretation, then the control system can perform complex data validation and processing, but the response time increases and external control becomes slower
Solution Approach 1:
The system segments control data transmission into two distinct paths: a normal path for regular control operations that includes interpretation and validation, and an emergency path for urgent external control that bypasses interpretation. This segmentation allows the system to maintain reliable data validation for normal operations while enabling rapid response for emergency situations through the bypass mechanism.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the in-vehicle wireless communication apparatus with the capability to receive and forward control data directly to the in-vehicle network without interpretation. The data format and transmission protocols are predetermined, allowing the system to act immediately when emergency control is required without waiting for interpretation or validation steps.
2Measurement precision
If control data undergoes interpretation by the in-vehicle control apparatus, then the system can ensure proper processing and control accuracy, but the control speed decreases
Solution Approach 1:
The in-vehicle wireless communication apparatus serves as an intermediary that can handle control data in two ways: for normal operations, it forwards data through the in-vehicle control apparatus for interpretation and accuracy assurance; for emergency operations, it acts as a direct mediator that bypasses the interpretation step and delivers control data straight to the in-vehicle network, achieving both accuracy and speed through context-dependent routing.
Solution Approach 2:
The system dynamically adjusts the control data processing path based on the urgency of the control request. The in-vehicle wireless communication apparatus can switch between interpretation mode (for normal control accuracy) and bypass mode (for emergency control speed), making the system adaptable to different operational requirements and achieving optimal balance between accuracy and speed.
3Adaptability or versatility
If the system uses standard wireless communication protocols with data interpretation, then the system is more adaptable to different control scenarios, but the data transmission complexity and processing time increase
Solution Approach 1:
The system segments the data processing function into interpretation processing (for adaptable control scenarios) and direct transmission processing (for simplified emergency control). This segmentation reduces the overall processing complexity by providing a direct path that bypasses interpretation, while maintaining adaptability through the available interpretation path for non-emergency scenarios.
