Brake Feedback System Evaluating Auxiliary Brake Usage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy vehicle operators face challenges in evaluating and reducing fuel consumption and wear caused by incautious driving and unfavorable traffic conditions, particularly in the use of brake systems, as existing systems fail to accurately assess the driver's use of auxiliary brakes and provide effective feedback.
Innovation Solution
A brake feedback system that evaluates the driver's choice of braking systems by comparing the use of auxiliary brakes with total braking system usage during a braking action, calculates a brake assessment value, and provides recommendations for improved braking practices through a presentation means, encouraging the use of auxiliary brakes to reduce wear and fuel consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If auxiliary brakes are used more frequently, then wear on brake lining and brake drums is reduced, but the driver may not know how to use them optimally without proper evaluation feedback
Solution Approach 1:
The system provides feedback to the driver by evaluating their brake system choices and presenting information about preferred braking systems. The brake choice evaluation means compares the driver's use of brake systems with optimal usage patterns and delivers feedback through a presentation means, enabling the driver to learn and improve their brake selection decisions while reducing wear through better auxiliary brake utilization.
2Force
If the service brake is used on long downhill slopes, then immediate braking force is provided, but overheating of brake discs and drums occurs causing brake failure and increased wear
Solution Approach 1:
The system changes the operational parameters of the braking system by encouraging the use of auxiliary brakes that operate at lower temperatures. The evaluation means assesses whether the driver is using auxiliary brakes appropriately for conditions like long downhill slopes, and provides feedback to promote parameter changes in braking behavior that prevent overheating while maintaining effective braking force.
3Measurement precision
If existing brake evaluation systems are used, then basic brake usage is tracked, but accurate assessment of driver's auxiliary brake usage and provision of effective feedback is not achieved
Solution Approach 1:
The system addresses the information loss by implementing a comprehensive feedback loop. The brake choice evaluation means not only measures auxiliary brake usage with improved precision but also processes this information and delivers actionable feedback to the driver through a presentation means, ensuring that the driver receives the information needed to improve their braking behavior.
Solution Approach 2:
The system segments the evaluation process into distinct components: tracking auxiliary brake usage, comparing with optimal patterns, calculating evaluation results, and delivering feedback. This segmentation enables more precise measurement of auxiliary brake usage and ensures that feedback information is systematically processed and delivered to the driver.

AI summary
A brake feedback system for a vehicle comprising a brake choice evaluation means arranged to evaluate the driver's choice of braking system, e.g. auxiliary brakes and service brake, by comparing the driver's use of at least one braking system, with a total use of the braking systems in the vehicle during a braking action, wherein the driver's use of at least one auxiliary brake system is determined based upon at least one brake power model of the at least one auxiliary brake system, and wherein the brake choice evaluation system is arranged to grade the driver's choice of braking system and to feedback recommendations about a preferred braking system and/or function to the driver on a presentation means.
