Control system and method for brake bleeding
First Claim
1. A system comprising:
- a force sensor detecting one or more forces generated by a machine assembly acting to move a brake lever of a vehicle in order to open a valve of an air brake system of the vehicle;
an encoder detecting displacement of the machine assembly as the machine assembly acts to move the brake lever;
an acoustic sensor monitoring one or more sounds generated during or after the machine assembly acts to move the brake lever; and
a controller determining that the brake lever has been moved to a position to open the valve of the air brake system to release the air brake system based on the one or more forces that are detected, the displacement that is detected, and the one or more sounds that are monitored.

Abstract
A robotic system validates brake bleeding by detecting one or more forces generated by a machine assembly acting to move a brake lever of a vehicle in order to open a valve of an air brake system of the vehicle. The system also detects displacement of the machine assembly as the machine assembly acts to move the brake lever, monitors one or more sounds generated one or more of during or after the machine assembly acts to move the brake lever, and determines that the brake lever has been moved to a position to open the valve of the air brake system to release the air brake system based on the one or more forces that are detected, the displacement that is detected, and/or the one or more sounds that are monitored.

10. A method comprising:
-
detecting one or more forces using a force sensor, generated by a machine assembly acting to move a brake lever of a vehicle in order to open a valve of an air brake system of the vehicle; detecting displacement using an encoder, of the machine assembly as the machine assembly acts to move the brake lever; monitoring one or more sounds using an acoustic sensor, generated during or after the machine assembly acts to move the brake lever; and determining using a controller, that the brake lever has been moved to a position to open the valve of the air brake system to release the air brake system based on the one or more forces that are detected, the displacement that is detected, and the one or more sounds that are monitored. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method comprising:
-
detecting one or more of; a force using a force sensor, generated by a machine assembly acting to move a brake lever of a vehicle in order to open a valve of an air brake system of the vehicle; displacement using an encoder, of the machine assembly as the machine assembly acts to move the brake lever;
orsound using an acoustic sensor, generated during or after the machine assembly acts to move the brake lever; and determining using a controller, that the brake lever has been moved to a position to open the valve of the air brake system to release the air brake system based on one or more of the force, the displacement, or the sound that is detected. - View Dependent Claims (17, 18, 19, 20)
