REGENERATIVE BRAKING IN THE PRESENCE OF AN ANTILOCK BRAKING SYSTEM CONTROL EVENT

摘要

A hybrid electric vehicle includes at least one wheel, a friction brake, a motor, and at least one controller. The friction brake is coupled to the wheel and configured to provide friction brake torque, and the motor is coupled to the wheel and configured to provide regenerative brake torque. The controller is configured to command the motor to provide a regenerative brake torque to satisfy a low frequency torque component or a high frequency torque component of a required antilock wheel brake torque during an antilock braking event.

1. A vehicle comprising:
a wheel; a friction brake coupled to the wheel and configured to provide friction brake torque; a motor coupled to the wheel and configured to provide regenerative brake torque; and at least one controller configured to filter a requested antilock wheel brake torque into different frequency components and command the motor to provide a regenerative brake torque to satisfy one of the frequency components during an antilock braking event.
