Abstract
A brake control system is provided for a vehicle having steerable front wheels, left and right brake units for braking left and right rear wheels, and a single manually operated brake input device. A main brake valve has a supply port, a return port, an outlet and a valve spool for controlling communication therebetween. The valve spool is coupled to a brake input device. A normally open left turn valve controls communication between the outlet and the left brake unit. A normally open right turn valve controls communication between the outlet and the right brake unit. A normally open balance valve controls communication between the left and right brake units. The system includes a brake input device sensor, a turn angle sensor and a vehicle speed sensor. A control unit controls the left and right turn valves and the balance valve as a function of signals from the sensors.
