  • Regenerative braking system and method for controlling a regenerative braking system
    Patent number: 9260087
    Abstract: A brake system for a vehicle having a hydraulic brake system and a regenerative brake system and a method of controlling the same is provided. The brake system may include a brake pedal having a range of motion and configured to control the application of the hydraulic brake system based upon a position of the brake pedal within the range of motion. The brake system may further include a brake controller configured to determine an inflection position of the brake pedal, the inflection position being a position of the brake pedal within the range of motion when the hydraulic brake system begins to apply a brake pressure over a predetermined threshold, wherein the brake controller applies the regenerative brake system based upon inflection position.

  • Method of detecting an in-range failure of a brake pedal position sensor
    Patent number: 8634985
    Abstract: A method of detecting an in-range failure of a brake pedal position sensor includes calculating the difference between a minimum position and a maximum position of the brake pedal position sensor. The calculated difference is weighted to define a fast test weighted input value and/or a full test weighted input value. A cumulative test result value is incremented by the fast test weighted input value and/or the full test weighted input value. The cumulative test result value is filtered to define a moving average of the cumulative test result value after each incremented occurrence. The moving average of the cumulative test result value is tracked to determine if the brake pedal position sensor is functioning properly.
