Lane Change Safety Display With Real-Time Risk Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lane change assistance systems fail to provide real-time, intuitive danger level information, making it difficult for drivers to make safe driving decisions during lane changes.
Innovation Solution
A method and apparatus that determine a lane change safety status in real-time and dynamically display it using a visual indicator, such as a dashboard progress bar or head-up display, based on vehicle and target vehicle speed and acceleration data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a driver uses accelerated lane change method, then lane change speed is improved, but safety deteriorates due to insufficient acceleration and too short vehicle distance
Solution Approach 1:
The system continuously monitors the distance to the following vehicle and provides real-time feedback to the driver through visual displays and haptic feedback, enabling the driver to adjust acceleration based on the dynamic safety assessment. This closed-loop feedback mechanism allows the driver to achieve faster lane changes while maintaining safety by adjusting behavior based on real-time data.
Solution Approach 2:
The safety assessment is not static but dynamically updated throughout the lane change process. The system calculates safety status at multiple stages (before lane change, during lane change, after lane change) and adjusts the safety level indication in real-time, allowing the driver to respond to changing conditions and optimize both speed and safety.
2Reliability
If a driver uses braking and waiting method, then safety is improved, but productivity deteriorates due to miss of lane change opportunity
Solution Approach 1:
The system performs preliminary safety assessment before the lane change is initiated and provides advance warning to the driver. By calculating the safety status in advance and providing visual indicators, the driver can make informed decisions about whether to proceed with the lane change, avoiding unnecessary braking and waiting while maintaining safety.
Solution Approach 2:
The system empowers the driver with the information needed to make safe lane change decisions independently. Rather than automatically controlling the vehicle, the system provides real-time safety assessment and lets the driver self-adjust their driving behavior, balancing safety and efficiency based on the displayed information.
3Loss of information
If a system uses buzzing reminder method, then information transmission is achieved, but ease of operation deteriorates because driver cannot intuitively learn risk dynamically
Solution Approach 1:
The system uses color-coded visual indicators (green, yellow, red zones) to represent different safety levels, making the risk information immediately intuitive and easy to understand. This visual representation allows the driver to quickly grasp the safety status without needing to interpret complex data or rely on auditory warnings alone.
Solution Approach 2:
The system transforms the one-dimensional auditory warning (buzzing) into a two-dimensional visual display with spatial positioning. The safety status is displayed as a visual indicator showing both the current safety level and the trend (improving or worsening), providing richer information in a more intuitive format that enhances driver understanding.

AI summary
The present disclosure provides a method and an apparatus for assisting in vehicle lane change. The method comprises: determining a lane change safety status corresponding to a current lane change behavior of a vehicle; and dynamically displaying the lane change safety status to enable a driver to dynamically receive information about changes in danger level throughout an entire lane change process.
