Vehicle Controller Degradation for Hacking-Safe Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems lack effective methods to handle cyber hacking, particularly in level 4 autonomous driving where the system controls all driving functions, leading to undefined operational strategies for controllers when hacking occurs.
Innovation Solution
An apparatus and method that includes a hacking monitoring system to detect hacking attempts, sets a safety zone, and adjusts controller performance to guide the vehicle into the safety zone, reducing or stopping functions of compromised controllers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system maintains full controller performance for autonomous driving operations, then driving functionality is preserved, but system vulnerability to hacking increases
Solution Approach 1:
The patent implements dynamic performance adjustment of controllers based on security risk levels. When hacking is detected, the system transitions from full performance mode to reduced performance mode, dynamically adapting controller operations to balance safety and functionality. This is achieved through real-time monitoring of controller states and adjusting performance parameters accordingly.
Solution Approach 2:
The system changes operational parameters of controllers based on security conditions. When a controller is identified as compromised, the system modifies performance parameters (such as power output, response speed, or operational limits) to reduce the impact of potential hacking while maintaining essential driving functions. This parameter adjustment allows the system to operate in a degraded but safe manner.
2Object-affected harmful factors
If the system reduces controller performance to mitigate hacking risks, then system security is improved, but driving capability deteriorates
Solution Approach 1:
The patent segments the control system into multiple independent controllers, each managing specific driving functions. When hacking is detected in one controller, only that specific controller's performance is adjusted, while other controllers continue to operate at full capacity. This segmentation allows the system to maintain essential driving capabilities even when individual controllers are compromised.
Solution Approach 2:
The system applies partial performance reduction only to affected controllers rather than shutting down the entire system. By maintaining full performance in unaffected controllers and applying reduced performance selectively, the system preserves sufficient driving capability while mitigating the specific security risk posed by the hacked controller.
3Reliability
If the system implements comprehensive hacking monitoring and controller performance adjustment, then security response capability is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the hacking monitoring system continuously observes controller states and communicates security risk levels to the vehicle control device. This feedback loop enables automatic performance adjustment without requiring complex manual intervention systems. The monitoring system provides real-time information about controller integrity, and the control device responds by adjusting performance parameters based on predefined security protocols.
