Abstract
A vehicle braking system includes a wheel cylinder, a brake pedal, a master cylinder, a master cylinder circuit, a primary braking unit operable to generate a braking force at the wheel cylinder in a primary mode, decoupled from the master cylinder circuit, a secondary braking unit including a second electrically-actuated pressure generating unit and operable to generate a braking force at the wheel cylinder in a secondary mode of operation, a plurality of valves configured to provide anti-lock braking at the wheel cylinder upon loss of traction during braking in the primary mode of operation, and a controller programmed to actuate the plurality of valves and further programmed to actuate the second electrically-actuated pressure generating unit upon loss of traction in the primary mode of operation to generate pulsations within the master cylinder circuit to provide a feedback force at the brake pedal indicative of the anti-lock braking.
