    摘要: A method and apparatus for limiting an assistance-torque demand on an actuator, for example a servomotor, of a power steering system. An assistance-torque demand is received and examined based on a predetermined limit criterion. If a violation of the limit criterion is ascertained, a transient assistance-torque limit is adopted and progressively reduced so long as the violation of the limit criterion is ascertained. The assistance-torque demand is limited based on the transient assistance-torque limit. The limited assistance-torque demand is sent to an interface of the actuator of the power steering system.
