Abstract
An electro-hydraulic braking system of the type capable of operating 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, wherein when it is detected that there exists within the system a prescribed category of non safety-critical fault, it is arranged that the driver is caused to experience a modified, different to usual, travel/force behaviour characteristic through the braking pedal when braking.
