- 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.

- 1. A method of compensating for drive influences in a drive train of a vehicle equipped for regenerative braking and having a power steering system including a servomotor configured to provide torque to a vehicle steering rack, the method comprising:
commanding the servomotor to apply a compensation torque to the vehicle steering rack in response to a steering rack difference magnitude exceeding an associated threshold due to a regenerative braking event.
