Abstract

A system for controlling regenerative braking in an electrified vehicle to prevent or minimize reduction of overall braking torque during wheel slip events includes an antilock braking system adapted to transmit an antilock braking system active signal and a regeneration powertrain interfacing with the antilock braking system. The regeneration powertrain is adapted to inhibit regenerative braking torque reduction responsive to receiving the antilock braking system active signal during a high deceleration braking event. A method for controlling regenerative braking in an electrified vehicle to prevent or minimize reduction of overall braking torque during wheel slip events is also disclosed.
