US Patent 10112587 Electronic braking system

A vehicle braking system includes a service brake pedal and a sensing device configured to monitor a position of the service brake pedal. A processing device is configured to control an amount of braking force provided by the vehicle braking system as a function of the position of the service brake pedal. The braking system further includes a return spring operatively coupled to the service brake pedal and configured to provide a substantially linear pedal effort feedback during an initial range of motion of the service brake pedal. Additionally, a damping device that operates in compression as the service brake pedal is depressed is configured to provide a substantially non-linear pedal effort feedback during a subsequent range of motion of the service brake pedal.
