#CMT# #/CMT# The method involves determining self aligning torque basic value (Mrsm), tracking torque basic value (Mshm) and steering torque. Two weighting factors are determined based on the steering torque. A modified self aligning torque and a modified tracking torque are determined based on the determined basic values with the help of determined weighting factors. A correcting variable (Mem) for steering wheel actuator (10) is determined from the modified self aligning torque and the modified tracking torque. The steering wheel actuator is controlled according to the correcting variable. #CMT#USE : #/CMT# Method for controlling a steering wheel actuator i.e. electric motor, in a steer by wire steering system in a vehicle. #CMT#ADVANTAGE : #/CMT# The correcting variable for steering wheel actuator is determined from the modified self aligning torque and the modified tracking torque and the steering wheel actuator is controlled according to the correcting variable, thus preventing system instabilities and ensuring desired system performance with minimum expenditure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a steer by wire vehicle steering system. Mem : Correcting variable for steering wheel actuator Mrsm : Self aligning torque basic value Mshm : Tracking torque basic value 10 : Steering wheel actuator 12 : Steer by Wire vehicle steering system. |
