Vehicle brake control system

摘要

A vehicle brake control system includes a regenerative braking control component, a frictional braking control component, a calculating component and a controlling component. The regenerative braking control component controls a regenerative braking device to provide a regenerative braking torque. The frictional braking control component controls a frictional braking device to provide a frictional braking torque. The calculating component calculates a regenerative braking torque filter processing value based on a fluctuation frequency of the regenerative braking torque. The controlling component, during a first condition, operates a motorized power assist control device based on the regenerative braking torque filter processing value, instead of the regenerative braking torque, to moderate the frictional braking torque, such that the regenerative braking torque and the moderated frictional braking torque provide a target braking torque based on a braking operation.
