Vehicle braking system and method of operating the same

A method of operating a vehicle braking system, the method comprising:

• actuating an electronically controlled pressure generating unit;
• pressurizing fluid along a first fluid pressurization path defined from the electronically controlled pressure generating unit, through the master cylinder, and to a first wheel cylinder;
• and
• pressurizing fluid along a second fluid pressurization path defined from the electronically controlled pressure generating unit to a second wheel cylinder, the second path bypassing the master cylinder,
• wherein the first path is pressurized concurrently with the second path.

A vehicle braking system comprising:

• a first wheel cylinder;
• a second wheel cylinder;
• a master cylinder including a first piston and a second piston;
• a braking input device coupled to the master cylinder;
• an electronically controlled pressure generating unit separate from the master cylinder;
• a first valve positioned between the electronically controlled pressure generating unit and the master cylinder;
• a second valve positioned between the master cylinder and the second wheel cylinder, and
• a third valve positioned between the electronically controlled pressure generating unit and the second wheel cylinder;
• wherein the vehicle braking system is operable to provide braking in a first configuration in which the first valve is in an open position, the second valve is in a closed position, and the third valve is in an open position such that the vehicle braking system operates as a brake-by-wire system with direct feedback to the braking input device.
