Abstract
A power steering control apparatus for a motor vehicle which ensures an appropriate steering force conforming to the prevailing road condition and hence the safety for the motor vehicle even when the wheels are locked due to hard brake applied on a slippery road. The apparatus includes a first microcomputer for determining a driving torque of a steering assist motor on the basis of steering torque information generated upon steering of a steering wheel and pseudo vehicle speed information to thereby generate and output a driving signal for the steering assist motor on the basis of the driving torque, and a second microcomputer for generating the pseudo vehicle speed signal on the basis of wheel rotation speed signals and acceleration/deceleration signal of the motor vehicle to thereby generate and output a brake actuation signal for wheels of the motor vehicle on the basis of the pseudo vehicle speed signal, the acceleration/deceleration information and brake application information. The first microcomputer may further include a memory for storing steering assist characteristics according to which the torque of the assist motor is changed.
