Abstract
An electronic braking system for a vehicle wherein control of the vehicle brakes is achieved by the use of electric control signals generated at a brake pedal in response to a driver's braking demand and an electronic controller which is adapted to control the supply of fluid under pressure from a power source to the brakes in accordance with said electronic signals corresponding to the driver's demand, the system being adapted to raise the brake pressure to a first predetermined level(jump-in) at a prescribed level of initial brake pedal travel and to release the brake pressure (reverse jump-in) as a second predetermined level, which is lower than at jump-in. The jump-in brake pressure level can be arranged to be variable with vehicle speed. In some cases, the brakes are arranged to be prefilled to a low pressure at a low pressure at an early stage in the pedal travel and then maintained at that low level until jump-in is triggered, whereupon the braking pressure is raised to the jump-in level. In other cases where jump-in is not necessarily used, the prefill pressure is maintained at that level until actual brake demand exceeds the prefill pressure whereupon the brake pressure is then controlled in accordance with actual brake demand.
