Autonomous Driving Alert System for Route Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving systems in vehicles often fail to switch to autonomous operation due to malfunctioning communication devices, leading to safety concerns as drivers become complacent on frequently used routes and may not be alerted to non-autonomous road sections.
Innovation Solution
A driver assistance system with an operating mode detection unit that assesses the possibility of autonomous driving based on stored route use data and communicates with vehicle-external devices to generate alerts for the driver through signaling units when autonomous operation is not possible, using a combination of database, navigation systems, and vehicle-to-infrastructure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous driving operation is implemented on road sections with communication devices, then driving automation and convenience are improved, but safety deteriorates when communication devices malfunction and drivers become complacent
Solution Approach 1:
The system continuously monitors the operational status of communication devices and provides feedback to the driver through the signaling unit. When a malfunction is detected, the system alerts the driver to switch from autonomous to manual driving mode, creating a closed-loop feedback mechanism that maintains safety despite automation
Solution Approach 2:
The operating mode detection unit proactively detects malfunctions in communication devices before they compromise safety. By identifying issues with vehicle-external communication devices in advance, the system can warn the driver and prevent unsafe autonomous operation, rather than reacting after a problem occurs
2Ease of operation
If drivers rely on autonomous systems for frequently used routes, then ease of operation is improved, but safety deteriorates due to driver complacency and lack of attention
Solution Approach 1:
The system provides continuous feedback about the actual operational mode to the driver, preventing complacency by making the system's limitations transparent. When autonomous operation is not possible despite driver expectations, the signaling unit alerts the driver, maintaining situational awareness and safety
Solution Approach 2:
The system preemptively counteracts driver complacency by detecting when autonomous operation cannot be performed and alerting the driver before unsafe conditions develop. This preliminary warning prevents the harmful effect of driver inattention from manifesting
3Reliability
If the system continuously monitors communication device status and route use data, then safety is improved, but device complexity increases
Solution Approach 1:
The operating mode detection unit performs multiple functions: monitoring communication device status, analyzing route use data, determining autonomous operation feasibility, and triggering warnings. By consolidating these diverse functions into a single multi-functional unit, the system achieves enhanced safety without proportionally increasing overall system complexity
Solution Approach 2:
The system combines communication device monitoring, route data analysis, and driver alerting into an integrated safety monitoring system. By merging these functions that work together toward the common goal of safety, the patent reduces the complexity that would arise from separate independent systems
Data Source
AI summary
The disclosure relates to a driver assistance system for a vehicle. The driver assistance system has an operating mode detection unit and a signaling unit. The operating mode detection unit is configured to detect whether autonomous operation of the vehicle is possible for a road section and, in case autonomous operation of the vehicle is not possible, to generate a signal and/or message taking into account stored route use data and send it to the signaling unit. The signaling unit is configured to receive the signal and to generate signaling for the driver.
