Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As vehicles age, the braking distance increases due to brake pad and disc wear, leading to safety concerns as the braking distance exceeds the design safety range, and existing technologies lack a solution to dynamically adjust braking pressure based on varying traveling conditions using artificial intelligence.
Innovation Solution
A brake control system that includes a measuring apparatus to monitor vehicle speed, brake pad wear, traveling distance, and braking pressure, and a controller connected to a processor using an AI model to learn and adjust the braking pressure to maintain a safe braking distance by comparing initial and current braking distances and applying additional pressure as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the vehicle operates for a long duration, then the vehicle accumulates traveling experience, but the braking distance increases due to brake pad and disc wear
Solution Approach 1:
The system dynamically changes the braking pressure parameter based on the vehicle's operating duration and wear level. As the brake pad wear level increases over time, the controller adjusts the braking pressure to compensate for the increased braking distance, thereby maintaining safe stopping distances despite prolonged vehicle operation
Solution Approach 2:
The measuring apparatus continuously monitors the braking distance and brake pad wear level, providing feedback to the controller. The controller uses this feedback to adjust the braking pressure in real-time, creating a closed-loop control system that maintains optimal braking performance throughout the vehicle's operating life
2Length of moving object
If the braking pressure is increased to reduce braking distance, then the braking distance decreases, but the wear of brake pad and disc accelerates
Solution Approach 1:
The system dynamically adjusts the braking pressure based on the real-time wear level of the brake pad and disc. Rather than using a fixed high pressure, the controller modulates the braking pressure to match the current condition of the braking components, reducing unnecessary wear while maintaining safe braking distances
Solution Approach 2:
The system performs preliminary assessment of the brake pad wear level and predicts the required braking pressure adjustment before actual braking occurs. This allows the controller to prepare the optimal braking pressure that achieves safe stopping distance without excessive wear
3Device complexity
If a fixed braking pressure is used, then the control system is simple, but the braking distance cannot adapt to varying traveling conditions and wear levels
Solution Approach 1:
The brake control system performs self-adjustment by automatically monitoring its own operating conditions (brake pad wear level, traveling distance, vehicle speed) and autonomously adjusting the braking pressure accordingly. This self-service capability enables the system to adapt to varying conditions without complex external control

Function Achieved in This Case

AI summary
The present disclosure discloses a brake control system for use in a vehicle and a control method thereof. A brake control system may be configured to include a brake pad for braking the vehicle by pressing a brake disc provided in the vehicle, a measuring apparatus for measuring the vehicle speed, the wear level of the brake pad, the traveling distance of the vehicle, the braking distance of the vehicle, and the braking pressure applied by the brake pad to the brake disc at braking, and a controller connected with the measuring apparatus and for controlling an operation of the brake pad. The controller may compare an initial braking distance, which is a design value of the braking distance before initial traveling of the vehicle, with a current braking distance, which is a braking distance after traveling of the vehicle during a certain duration, and increase the braking pressure of the brake pad in response to the amount of increase in the braking distance, when the amount of increase in the braking distance, which is a difference value between the current braking distance and the initial braking distance, is out of a setting range. The brake control system may transmit and receive a wireless signal in a mobile communication network constructed according to 5G (Generation) communication.
