Method of controlling the brake bias in a vehicle braking system

摘要

A method and system for controlling the overall brake bias in a vehicle braking system having both frictional and regenerative braking devices. The method comprises receiving a brake bias command and determining a desired brake bias based on the brake bias command. The method further comprises changing the brake bias in the vehicle braking system to achieve the desired brake bias through the operation of one or more regenerative braking devices. The system comprises one or more regenerative braking devices, each configured to apply negative torque to one of a first axle or a second axle of the vehicle, and an electronic module, for example, an electronic brake control module (EBCM) that is configured to perform the above-described methodology.

1. A method of controlling the overall brake bias in a vehicle braking system having both frictional and regenerative braking devices, comprising the steps of:
receiving a brake bias command; determining a desired brake bias based on the brake bias command, wherein brake bias relates to the amount of negative torque applied to a first axle of the vehicle by one or more braking devices operatively coupled thereto compared to the amount of negative torque applied to a second axle of the vehicle by one or more braking devices operatively coupled thereto; and changing the overall brake bias in the vehicle braking system to achieve the desired brake bias through the operation of one or more regenerative braking devices; wherein a brake bias between one or more frictional braking devices operatively coupled to the first axle and one or more frictional braking devices operatively coupled to the second axle remains the same throughout the changing of the overall brake bias.
