ABSTRACT:
An electric power steering system for vehicles (200) including a drive control circuit (30, 45, 53) for giving a drive signal (Va) to an electric motor (18) for producing auxiliary torque to be applied to an output shaft (5), taking into consideration an output signal (S.sub.1, S.sub.2) from a steering torque detection mechanism (31) for detecting steering torque (Ts) acting on an input shaft (4). The steering system (200) further comprises a mechanism (35) for detecting the steering speed (Ns) of the input shaft (4) and a mechanism (115, 116, 122-126, 130-132) for detecting the steering acceleration (dNs) of the input shaft (4), and the drive control circuit (30, 45, 53) is adapted to give the motor drive signal (Va) to the electric motor (18), taking into consideration an output signal (S.sub.3, S.sub.4) from the steering speed detecting mechanism (35) and an output signal (dNs) from the steering acceleration detecting mechanism (115, 116, 122-126, 130-132) in addition to the steering torque signal (S.sub.1, S.sub.2). The drive control circuit (30, 45, 53) includes a microcomputer unit (30) adapted to determine and output a control signal (T.sub.3, T.sub.4) constituting the basis of the motor drive signal (Va) in an address designation manner in dependence of the steering torque signal (S.sub.1, S.sub.2), the steering speed signal (S.sub.3, S.sub.4), and the steering acceleration signal (dNs).
