A method for determining a supporting torque - setpoint value for an electric motor-driven power steering system

摘要

A process for the determination of a supporting torque - set value (m_U) for an electric motor-driven power steering system comprises the following steps:a) it is a steering torque (m_sens) determined;b) it is a vehicle speed (v) determined;c) it is a motor angle speed (ω) is determined;d) from a predetermined set of characteristic curves (20), at least as a function of the vehicle speed (v) and the motor angle speed (ω) a characteristics field output size (k_Klf, M_Klf) ; ande), starting from the detected steering torque (m_sens) , while taking into account the characteristics field output size (k_Klf, M_Klf) the supporting torque - desired value (m_U) for the power steering system is determined.
