VEHICLE BRAKE CONTROL SYSTEM AND METHOD

Abstract:

A brake control system includes one or more processors communicatively connected to at least one sensor configured to output at least one property measurement of air in a brake pipe of a vehicle braking assembly. The one or more processors are configured to determine, based on the at least one property measurement, a pressure reduction lower limit (PRLL) in the brake pipe. The one or more processors are further configured to control movement of a vehicle system that includes the brake pipe to enforce the PRLL by preventing a pressure reduction in the brake pipe that is less than the PRLL while one or more air reservoirs of the vehicle braking assembly are at a reduced charge state.
