Lead Vehicle Braking Warning System Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lead vehicle braking warning systems only indicate if a lead vehicle is braking, without distinguishing the type or severity of deceleration, which can lead to inadequate responses from following vehicles.
Innovation Solution
A lead vehicle braking warning system installed in a host vehicle, equipped with a speed sensor, detector, display, and electronic controller, which determines the deceleration rate of a lead vehicle and displays specific images indicating light, medium, or hard braking conditions to the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a simple brake warning light system is used, then the device complexity is reduced, but the information provided to the driver is insufficient
Solution Approach 1:
The braking condition information is segmented into multiple discrete levels (light, medium, hard braking) and displayed separately. The display device divides the braking condition display area into multiple segments, each representing a different severity level, allowing the system to provide detailed information without requiring a completely complex new system architecture.
Solution Approach 2:
The system adds a new dimension of information display by showing not just whether braking is occurring, but the severity level through multiple display segments. This dimensional expansion of information presentation allows more comprehensive data communication without proportionally increasing hardware complexity.
2Loss of information
If multiple display segments are used to show different braking conditions, then the information completeness is improved, but the device complexity increases
Solution Approach 1:
The display device is designed to perform multiple functions: it can show different braking severity levels, indicate various vehicle states, and provide warning information. By making the display system multi-functional, the patent reduces the need for separate dedicated indicators for each function, thereby managing complexity while providing comprehensive information.
3Ease of operation
If the system provides detailed braking information, then the driver response accuracy is improved, but the processing requirements increase
Solution Approach 1:
The system monitors changes in deceleration parameters and transitions the display between different braking condition segments based on these parameter changes. By focusing on detecting parameter changes rather than continuously processing all possible variables, the system provides accurate real-time information while managing electronic control complexity.

AI summary
A lead vehicle braking warning system includes a speed sensor, a detector, a display and an electronic controller. The speed sensor measures current speed of a host vehicle. The detector detects current speed of a lead vehicle relative to the speed of the host vehicle. The display has a braking condition display area configured to display each of a plurality of braking conditions of the lead vehicle for the operator of the host vehicle. The electronic controller is in electronic communication with the speed sensor, the detector and the display. The electronic controller determines whether or not the lead vehicle is currently decelerating and determine which one of a plurality of braking conditions is currently being experienced by the lead vehicle and display information identifying the current one of the plurality of braking conditions of the lead vehicle within the braking condition display area of the display.
