Vehicle Hazard Switch Logic During Driver Trouble Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems struggle to accurately determine the intention of passengers or drivers when operating the hazard switch during driving trouble tackling control, leading to inappropriate stopping or continuation of critical safety controls.
Innovation Solution
The vehicle control apparatus is designed to differentiate between the intentions of passengers or drivers by monitoring the timing and context of hazard switch operations relative to the initiation of driving trouble tackling control and hazard lighting processes, allowing for precise control of deceleration and hazard lighting processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system is structured to stop driving trouble tackling control when the hazard switch is operated, then the ease of operation is improved, but the reliability deteriorates because the control may be stopped when the passenger intends to announce the situation to those around
Solution Approach 1:
The system performs preliminary action by starting the hazard lighting process at a predetermined timing before potentially stopping the driving trouble tackling control. This ensures that the hazard lighting is already active to announce the situation to those around when the passenger operates the hazard switch, while still allowing the control to be stopped if the driver intended to use the switch to halt the control
Solution Approach 2:
The system uses feedback by monitoring the operation timing of the hazard switch relative to the driving trouble tackling control state. When the hazard switch is operated during the hazard lighting process, the system feedbacks this information to determine whether to stop the driving trouble tackling control, thereby resolving the contradiction between ease of operation and reliability
2Productivity
If the hazard lighting process is started at a predetermined timing as part of driving trouble tackling control, then the productivity is improved by automating the safety response, but the device complexity increases due to timing coordination requirements
Solution Approach 1:
The system merges the hazard lighting process with the driving trouble tackling control by integrating the timing coordination into the control flow. The hazard lighting process is started at a predetermined timing as part of the driving trouble tackling control, eliminating the need for separate control mechanisms and reducing overall device complexity while maintaining automated safety response

AI summary
A vehicle control apparatus includes a memory storing instructions; a processor operatively coupled to the memory and configured to execute the instructions stored in the memory, in which the instructions cause the vehicle control apparatus to: (i) start driving trouble tackling control based on determining that a driver of the vehicle is in a driving trouble state where the driver has trouble driving the vehicle, and (ii) start a hazard lighting process that is configured to turn on one or more hazard lights at a predetermined timing as a process of the driving trouble tackling control, and after execution of the driving trouble tackling control has started, turn on the one or more hazard lights without stopping the driving trouble tackling control based on determining that a hazard switch is operated before the predetermined timing in which the hazard lighting process is performed.
