Abstract
A vehicle brake system for a vehicle comprises at least one source of pressurized air for pressurizing the vehicle brake system, and a brake actuator configured to receive air from the source of pressurized air. A control is operatively associated with the source of pressurized air for selective application of the brake actuator. A supplemental parking brake control system is in communication with the control and the brake actuator. The control system is responsive to data indicative of gradient and speed vehicle conditions. The control system is configured to send a signal to the brake actuator to allow gradient and speed dependent supplemental parking. The control system is configured to prevent application of the brake actuator.
