Autonomous Driving Mode Shift for Hazard Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems fail to effectively mitigate accident risks in situations where multiple vehicles are driving in aggressive modes, such as sport or sport-plus modes, leading to increased likelihood of accidents due to aggressive driving maneuvers.
Innovation Solution
A vehicular hazard mitigation system that uses processors and memory to determine if a base vehicle is in an enhanced response driving mode and if other vehicles are within its alert zone, autonomously shifting the base vehicle's mode to a non-enhanced response driving mode to reduce aggressive driving tendencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a vehicle operates in enhanced response driving mode (sport mode), then driving performance and engine response are improved, but accident risk increases when other vehicles are in proximity
Solution Approach 1:
The system continuously monitors the driving environment by detecting other vehicles in proximity and automatically adjusts the driving mode based on this feedback. When another vehicle is detected in the alert zone, the system transitions from enhanced response mode to non-enhanced mode, and vice versa, creating a closed-loop control system that adapts to real-time conditions.
Solution Approach 2:
The driving mode is made dynamic rather than static, allowing automatic transition between enhanced response and non-enhanced modes based on the presence of other vehicles. This dynamic adjustment enables the vehicle to optimize performance when safe and reduce risk when other vehicles are nearby, without requiring manual driver intervention.
2Power
If multiple vehicles operate in enhanced response driving modes simultaneously, then individual vehicle performance is improved, but overall traffic safety deteriorates
Solution Approach 1:
Each vehicle independently monitors its environment and adjusts its driving mode based on detected conditions, creating a distributed feedback system across multiple vehicles. This prevents the escalation of aggressive driving behaviors that would occur if all vehicles maintained enhanced response modes simultaneously.
Solution Approach 2:
The system changes the operational parameters of the vehicle (driving mode) based on external conditions. By transitioning between enhanced response and non-enhanced modes, the vehicle adjusts its power delivery, steering response, and other performance parameters to match the safety requirements of the current traffic situation.
3Reliability
If autonomous control is implemented to switch driving modes, then accident prevention is improved, but system complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting unsafe conditions and switching driving modes without requiring driver input or complex external intervention. The vehicle monitors its own environment and autonomously adjusts its operating parameters, reducing the need for complex human-machine interfaces while maintaining high safety standards.
Solution Approach 2:
The autonomous control system integrates multiple functions into a single unified mechanism: environmental sensing, condition evaluation, mode selection, and execution of driving mode changes. This multi-functionality reduces overall system complexity compared to having separate systems for each function.

AI summary
A vehicular hazard mitigation system includes one or more processors and a memory communicably coupled to the processors. The memory may store a vehicular hazard mitigation module including computer-readable instructions that when executed by the processors cause the processors to determine a base vehicle currently driving in an enhanced response driving mode. After determining the base vehicle, at least one alert zone of the base vehicle is determined. A determination is then made as to whether at least one other vehicle is currently in the at least one alert zone of the base vehicle. If at least one other vehicle is currently in the at least one alert zone of the base vehicle, the vehicular hazard mitigation module may autonomously control operation of the base vehicle to shift the driving mode of the base vehicle from the enhanced response driving mode to a non-enhanced response driving mode.
