Regenerative braking system and method for controlling a regenerative braking system

摘要

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.

1. A brake system for a vehicle having a hydraulic brake system and a regenerative brake system, comprising:
a brake pedal having a range of motion and configured to control application of the hydraulic brake system based upon a position of the brake pedal within the range of motion; and a brake controller configured to determine an inflection position of the brake pedal, the inflection position corresponding to 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 the inflection position, and the brake controller is further configured to update the inflection position when a gradient of a current brake position and at least one periodically sampled brake position is less than a predetermined amount.
