Vehicle Safety System Prognosis Data Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety systems and automated driver assistance systems operate independently, leading to ineffective interventions in fully automatic vehicle operations, as they are designed for manual driving and lack accurate prognosis data for future vehicle guidance measures.
Innovation Solution
A standardized data interface is introduced to transmit prognosis data from a driver assistance system or independent prognosis module to the safety system, allowing for accurate prediction of future vehicle guidance measures and degree of automation, enabling early and appropriate interventions in fully automatic operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standardized data interface is introduced to transmit prognosis data from driver assistance system to safety system, then the safety system can function effectively in fully automatic mode with accurate future vehicle guidance measures, but the device complexity increases due to additional interface and data transmission infrastructure
Solution Approach 1:
The standardized data interface is designed to serve multiple functions: it transmits prognosis data from the driver assistance system to the safety system, and also supports data exchange in both manual and fully automatic driving modes. This multi-functional interface reduces the need for separate communication channels for different operating modes, thereby limiting the increase in system complexity while achieving reliable safety system operation across all modes.
Solution Approach 2:
The standardized data interface acts as an intermediary component that bridges the driver assistance system and the safety system. This mediator enables accurate transmission of prognosis data about future vehicle guidance measures, allowing the safety system to make informed decisions without requiring direct integration or complex point-to-point connections between systems.
2Object-affected harmful factors
If prognosis data transmission is implemented for early interventions, then accident risk is reduced through timely safety system responses, but the loss of time for data processing and transmission increases
Solution Approach 1:
The driver assistance system continuously generates and transmits prognosis data about future vehicle guidance measures before critical situations arise. By having this data available in advance through the standardized interface, the safety system can evaluate potential hazards and prepare intervention strategies without waiting for actual emergency conditions, thus reducing response time despite the added data transmission step.
Solution Approach 2:
The standardized data interface enables continuous feedback loops where prognosis data flows from the driver assistance system to the safety system, which then monitors and evaluates this data in real-time. This feedback mechanism allows the safety system to maintain an up-to-date understanding of future vehicle guidance measures and intervene promptly when hazards are detected, minimizing the effective response time.
3Adaptability or versatility
If the safety system monitors driver activities in manual operation, then driver autonomy is maintained with late interventions, but the loss of information about accurate future vehicle guidance measures occurs in fully automatic mode
Solution Approach 1:
The standardized data interface dynamically adapts to different operating modes. In manual driving mode, the safety system monitors driver activities and intervenes late to preserve driver autonomy. In fully automatic mode, the same interface provides the safety system with accurate prognosis data about future vehicle guidance measures from the driver assistance system, enabling the safety system to have the information it needs without requiring separate monitoring mechanisms for each mode.
