Abstract
Systems and methods for detecting wear in a braking system of a vehicle. The system includes a microphone and an electronic controller configured to receive an audio signal from the microphone, determine at least one sound characteristic of the audio signal, determine, based upon the at least one sound characteristic, a condition of a braking component of the braking system, generate a notification regarding the condition, and perform at least one selected from the group of sending the notification to a display for output to a user, storing the notification in a memory, and modifying operation of the vehicle.
Claims18
A system for monitoring brake wear in a braking system of a vehicle, the system comprising:
- a microphone;
- and
- an electronic controller configured to
- receive an audio signal from the microphone,
- determine a sound characteristic of the audio signal,
- determine, based upon the sound characteristic, a condition of a brake component of the braking system, wherein the condition of the brake component indicates a percentage of wear of the brake component, and wherein the percentage is correlated to the determined sound characteristic,
- generate a notification regarding the condition, and
- perform at least one selected from the group of sending the notification to a display for output to a user, storing the notification in a memory, and modifying operation of the vehicle.
A method for monitoring brake wear in a braking system of a vehicle, the method comprising:
- receiving, with an electronic controller, an audio signal from a microphone;
- determining, with the electronic controller, a sound characteristic of the audio signal;
- determining, with the electronic controller, a condition of a brake component of the braking system based upon the sound characteristic, wherein the condition of the brake component indicates a percentage of wear of the brake component, and wherein the percentage is correlated to the determined sound characteristic;
- generating, with the electronic controller, a notification regarding the condition;
- and
- performing, with the electronic controller, at least one selected from the group of sending the notification to a display for output to a user, storing the notification in a memory, and modifying operation of the vehicle.
