Vehicle Flashing Light Frequency Switching for Uniform Signal States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconsistency in flicker frequencies of vehicle flashing lights due to priority conflicts leads to nonuniform flicker states, making it difficult for drivers and external personnel to determine the vehicle's real state, increasing the risk of traffic accidents.
Innovation Solution
A method and apparatus that determine a switching moment based on the current and requested flicker frequencies to ensure consistent flicker frequencies before and after switching, ensuring uniformity and enabling accurate state recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If direct interruption processing is performed when a high-priority flashing light request conflicts with a low-priority flashing light, then the high-priority request is responded to immediately, but the flicker state becomes nonuniform and the transition is not smooth
Solution Approach 1:
The control device determines a switching moment before actually switching the flicker frequency, based on the current working state and flicker frequency of the flashing light. This preliminary determination ensures that the transition occurs at an optimal time, maintaining uniform flicker state while still responding to high-priority requests.
Solution Approach 2:
The system dynamically adjusts the switching moment based on the current working state and flicker frequency of the flashing light. Rather than using a fixed interruption method, the switching moment is determined adaptively to ensure smooth transitions and maintain flicker uniformity throughout the state change.
2Stability of the object's composition
If no processing is performed when a low-priority flashing light request conflicts with a high-priority flashing light, then the current high-priority state is maintained, but the driver and external personnel cannot know the real state of the vehicle
Solution Approach 1:
The control device uses feedback from the current working state and flicker frequency to determine the appropriate switching moment. This feedback mechanism ensures that the system maintains stability while still providing visible feedback to the driver and external personnel about the vehicle's real state through controlled transitions.
Solution Approach 2:
The system employs periodic flicker action with determined switching moments to communicate vehicle state information. By transitioning at calculated moments rather than continuously or never, the system maintains stability while periodically providing visible state information to users.
3Loss of time
If the flicker frequency is switched immediately upon receiving a flashing light switching request, then the response time is reduced, but the flicker frequency becomes nonuniform during transition
Solution Approach 1:
The control device performs preliminary determination of the switching moment based on current working state and flicker frequency before executing the frequency switch. This preliminary action reduces the effective transition time while ensuring that the actual switching occurs at an optimal moment, maintaining frequency precision.
Solution Approach 2:
The system dynamically determines the switching moment based on real-time working state and flicker frequency conditions. This dynamic approach optimizes both response time and frequency precision by adapting the switching moment to current system conditions rather than using a fixed or immediate switch.

AI summary
The present application provides a vehicle flashing light control method and apparatus, a vehicle and a storage medium. The method comprises: when a flashing light switching request is received, and a flashing light corresponding to the flashing light switching request and a current flashing light are the same flashing light, obtaining a first flashing frequency and a working state of the current flashing light, and a second flashing frequency of the flashing light corresponding to the flashing light switching request the working state comprising an on state and an off state of the flashing light, determining a switching moment according to the first flashing frequency and the working state of the current flashing light and the second flashing frequency; and switching a first flashing frequency output of the current flashing light to a second flashing frequency output at the switching moment, the working state being different from the working state of the current flashing light, such that the consistency of the flashing states before and atter switching can be avoided, the alternate occurrence of the on state and the off state of the flashing light and the unification of the flashing frequencies before and after switching are realized. and a driver and people outside the vehicle know the real state of the vehicle and traffic accidents are reduced.
