Abstract
An electro-pneumatic vehicle braking system including a control line, a modulator valve for controlling the supply of pressurised fluid to at least one brake actuator, a primary valve assembly and a secondary valve assembly, the primary valve assembly and the secondary valve assembly each being fluidly communicable with a source of pressurised fluid, and each of the primary and secondary valve assemblies being fluidly communicable with a control valve assembly, the control valve assembly being configurable in a first configuration to enable fluid communication between the primary valve assembly and the modulator valve, to provide a pneumatic control signal to the modulator valve, in a second configuration to enable fluid communication between the secondary valve assembly and the modulator valve, to provide a pneumatic control signal to the modulator valve, and in a third configuration in which fluid communication between either of the primary and secondary valve assemblies and the modulator valve is prevented and fluid communication between the control line and the modulator valve is enabled, to provide a pneumatic control signal to the modulator valve.
