Autonomous Vehicle Failure Routing and Safe Parking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicle systems lack effective mechanisms to manage failures during autonomous driving, which can lead to accidents if countermeasures are not prepared.
Innovation Solution
An autonomous vehicle control apparatus and method that includes a processor to determine the driving mode and execute logic for parking or driving, maintaining inter-vehicle distances, and navigating through congestion sections, even when failures occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous vehicle maintains standard driving operations, then normal driving efficiency is preserved, but the vehicle becomes vulnerable to accidents when failures occur
Solution Approach 1:
The system performs preliminary actions by pre-defining alternative driving routes and parking locations before failures occur. The processor stores multiple driving routes including alternative routes that avoid ramps, and identifies suitable parking locations in advance, enabling rapid response when failures are detected without requiring complex real-time decision-making
Solution Approach 2:
The control apparatus acts as an intermediary between the failure detection and the physical vehicle response. When a failure is detected, the control apparatus mediates the transition from normal driving mode to failure response mode by automatically executing pre-planned alternative routes or parking maneuvers, bridging the gap between failure detection and safe vehicle state
2Reliability
If the vehicle parks immediately upon failure detection, then safety is prioritized, but the vehicle may not reach its destination or complete its driving task
Solution Approach 1:
The system dynamically adjusts its response based on the vehicle's current state and location. The processor determines whether to execute alternative driving routes or parking mode logic based on real-time assessment of the driving situation, allowing the vehicle to continue to its destination when safe to do so, while prioritizing safety when necessary
Solution Approach 2:
The system changes operational parameters based on failure conditions. When failures are detected, the processor modifies driving parameters by selecting alternative routes with different characteristics (avoiding ramps) or changing the destination parameter to the nearest suitable parking location, thereby adapting the driving task to the failed state while maintaining productivity
3Stability of the object's composition
If the vehicle uses alternative driving routes avoiding ramps, then stability is improved during failures, but travel time increases due to longer routes
Solution Approach 1:
The system performs preliminary routing calculations to identify alternative routes that avoid ramps before failures occur. The processor stores these pre-calculated alternative routes, enabling immediate switching to stable driving paths when failures are detected, eliminating the need for time-consuming real-time route recalculation

AI summary
An apparatus and method for controlling a vehicle may comprise a processor and a memory. The processor determines whether a current driving situation of a broken vehicle in which the failure occurs is a parking mode or a driving mode, executes the parking mode logic to search for a parking location of the broken vehicle and parks the broken vehicle at the parking location, when the current driving situation is the parking mode, executes the driving mode logic such that the broken vehicle drives on driving route excluding a ramp while the broken vehicle maintains a first inter-vehicle distance from a forward vehicle, when the current driving situation is the driving mode, and executes the driving mode logic such that the broken vehicle drives while the broken vehicle maintains a second inter-vehicle distance longer than the first inter-vehicle distance, when the driving route includes a congestion section.
