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…
