Abstract
A vehicle includes at least one wheel, a parking brake associated with the at least one wheel and a service brake associated with the at least one wheel, and a braking control system. The braking control system interprets operator on/off commands to the parking brake. The service brakes are actuated instead of or in addition to the parking brake when a parking brake application is ordered and the vehicle speed falls outside a preferred vehicle speed range. If the vehicle is stopped and the parking brake is engaged, the parking brake is not disengaged responsive to an operator command until the service brake condition is within a preferred ready range.
