Abstract
A self monitoring vehicle braking system includes multiple sensors that gather data associated with the braking system. The data includes wheel speed, road inclination, moisture associated with a surface of the braking system, and audio associated with the road. A processor receives the data from the sensors and processes the data to determine whether a condition of the braking system falls within defined limits and provides to the driver of the vehicle an indication of the braking system condition.
Claims20
A self monitoring braking system suitable for a vehicle on a roadway comprising:
- a plurality of sensors for monitoring data associated with said braking system, said data including:
- speed of a wheel associated with said vehicle;
- inclination of said roadway;
- moisture associated with a surface of said braking system;
- and
- audio associated with said roadway;
- and
- a processor that receives said data from said plurality of sensors and processes said data to determine whether a condition of said braking system falls within defined limits and provides to a driver of said vehicle an indication of said condition of said braking system.
