Abstract
A vehicle braking system comprising an electro-hydraulic braking system of the type which operates normally in a brake-by-wire mode wherein hydraulic pressure is applied to braking devices at the vehicle wheels ( ) in proportion to the driver's braking demand as sensed electronically at a brake pedal ( ), and which, if the brake-by-wire mode should fail, operates in a push-through mode wherein hydraulic pressure is applied to the braking devices at the vehicle wheels ( ) by way of a master cylinder ( ) coupled mechanically to the braked pedal ( ), and an electric parking braking system for enabling the braking devices to be actuated for parking braking purposes. For supplementing the push-through braking provided by the electro-hydraulic braking system in the event that the brake-by-wire mode has failed, it is arranged that the operation of the brake pedal ( ) by the driver also causes operation of the electric parking braking system.
