Abstract

The invention relates to a method and an apparatus for electrically controlled assistance to a vehicle. In order to stabilize a vehicle in the event of oversteering, the invention provides that a nominal yaw damping torque is determined and is multiplied by an oversteer signal such that an additional torque is produced which is added, via an actuator in an electrically assisted power steering system, to its nominal torque, and is introduced into a vehicle steering system.
