Abstract
The braking system comprising an input mechanism, such as a brake pedal or a brake lever, actuated by a vehicle operator during brake application. A sensor senses the pressure exerted on the brake pedal and delivers a first electrical signal in accordance with that pressure. The system also includes a source of brake fluid under a constant fluid pressure and pressure modulators in fluid communication with the source and the wheel cylinders. An electronic control unit responds to the first signal and delivers to the pressure modulators a second electrical signal proportional to the first signal to cause the pressure modulators to communicate to the wheel cylinders a fluid pressure proportional to the second signal to apply the brake with a braking force proportional to the applied pressure. The braking system also provides an anti-skid function, traction control function, and braking force proportioning function.
