Electromechanical servo-steering system for vehicles, has correction unit with setpoint device which releases uncorrected motor-input signal according to driver command

摘要

The electromechanical servo-steering system has a correction unit with a setpoint device (29) which releases the uncorrected motor-input signal according to the driver command. The correction unit is provided with a failure model (28). A superposition gear shift (31) is provided, in which a correction signal is disabled on the uncorrected motor-input signal according to the driver command. The corrected motor-input signal is circulated from the correction signal for controlling a motor. An independent claim is included for a method for setting the moment-variations in a servo-steering system, where the moment variations are determined by drive motor.
