摘要： Methods for providing steering assistance for an electromechanical steering system having a redundant control unit with a primary and a secondary control path. Respective primary and secondary control paths each have a computing unit, gate driver module, and power module. The method includes detecting an applied steering torque; calculating a primary and secondary motor target torque in the primary computing unit as a function of the applied steering torque; transmitting the primary motor target torque to a primary motor controller of the primary computing unit; determining primary motor currents to operate a primary electric motor or a primary winding group of the electric motor in the primary motor controller; transferring the secondary motor target torque from the primary computing unit to a secondary motor controller and determining secondary motor currents for operation of a secondary electric motor or a secondary winding group of the electric motor.

摘要： Methods and systems for operating a vehicle occupant protection device of a steer-by-wire steering system. The system includes a steering wheel and an adjustable steering column connected to the steering wheel which can be adjusted between a retracted position and a deployed position via an adjustment mechanism. The steer-by-wire steering system has a feedback actuator to which a driver's request for a steering angle can be applied by a driver via the steering wheel, and which outputs a feedback signal to the steering wheel in response to the driver's request and a driving state of the motor vehicle. The method includes detecting an accident, detecting a hands-off situation or a hands-on situation, and when a hands-off situation has been detected, moving the steering column into an accident position by means of the adjustment mechanism, and triggering a steering wheel airbag during or after the adjustment process.
