ACTIVE TORQUE STEER COMPENSATION DURING NEGATIVE POWERTRAIN TORQUE FOR HYBRID AND ELECTRIC VEHICLES

摘要

A system and method for compensating for drive influences of a drive train of a vehicle, where the vehicle has a traction motor and a power steering system including a servomotor configured to provide torque to a vehicle steering rack, include commanding the servomotor to apply a compensation torque to the vehicle steering rack. The compensation torque is applied in response to a predicted drive influence caused by a regenerative braking torque.
