- the steering torque signal output from the high-pass filter 31 and the steering torque signal output from the peak hold unit 34 are multiplied by the multiplication unit 35. Since the steering torque signal output from the multiplication unit 35 is obtained by multiplying the signals processed by the high-pass filter 31 and the band-pass filter 32, the phase of the steering torque signal output from the torque sensor 12 is larger.

- the electric motor 10 is controlled by the assist correction current calculated based on the rectangular wave
- the steering feeling of the steering wheel 1 is deteriorated.
- the rectangular wave steering torque signal output from the limiter 38 is converted into a sine wave by the low-pass filter 39.
- the steering torque signal output from the low-pass filter 39 changes with a constant amplitude regardless of the magnitude of the steering torque signal (solid line in FIG. 4) output from the torque sensor 12. .

Therefore, the vibration of the steering wheel 1 is effectively suppressed.

Further, the assist correction current is compensated by the correction current compensator 36 so as not to attenuate even if the steering torque signal output from the torque sensor 12 is attenuated. Torque continuously acts at a constant magnitude in a direction that cancels vibrations input to the rack shaft 5. Therefore, vibration generated in the steering wheel 1 can be effectively suppressed by a simple method.

Is done.
- the reason for monitoring the vehicle speed is that vibration of the steering wheel 1 often occurs especially when the vehicle is traveling at high speed. Therefore, the vibration suppression control of the steering wheel 1 is performed only when the vehicle is traveling at high speed. Therefore, the predetermined range is set to 70 to 150 km / h, for example.
- the vibration of the steering wheel 1 is not a phenomenon that occurs only when the vehicle is traveling at a high speed, but is noticeable when the vehicle is traveling at a high speed and also when the vehicle is traveling at a low speed.
- the steering speed is monitored because vibration of the steering wheel 1 hardly occurs when the steering wheel 1 is cut and easily occurs when the steering wheel 1 is held. That is, the vibration of the steering wheel 1 is unlikely to occur when the steering wheel 1 is strongly gripped, and is likely to occur when the steering wheel 1 is lightly gripped. Therefore, when the steering angular speed is equal to or lower than a predetermined speed, for example, 10 deg / s, it is determined that the steering wheel 1 is being steered, and vibration suppression control of the steering wheel 1 is performed.

- the limiter variable processing unit 53 gradually increases or decreases the limit value set by the limiter 38 based on the determination result of the execution condition determination unit including the vehicle speed determination unit 50 and the steering angular velocity determination unit 51. Specifically, when the execution condition is switched from not established to established in the execution condition determining unit, that is, the vehicle speed determining unit 50 determines that the vehicle speed is out of the predetermined range, or the steering angular velocity determining unit 51 From the state where it is determined that the steering angular speed exceeds the predetermined speed, the vehicle speed determination unit 50 determines that the vehicle speed is within the predetermined range, and the steering angular speed determination unit 51 determines that the steering angular speed is equal to or less than the predetermined speed.
- the limiter variable processing unit 53 gradually increases the limit value set by the limiter 38 from 0 Nm to a predetermined upper limit value.
- the output signal output from the gain multiplier 37 through the limiter 38 gradually increases from 0 Nm to the upper limit value, so that the assist correction current gradually increases.
- the vehicle speed determination unit 50 determines that the vehicle speed is within the predetermined range, and the steering angular speed determination unit 51 determines the steering angular speed.
- the limiter variable processing unit 53 gradually decreases the limit value set by the limiter 38 from the upper limit value to 0 Nm. As a result, the output signal output from the gain multiplier 37 through the limiter 38 gradually decreases from the upper limit value to 0 Nm, so that the assist correction current gradually decreases.
- the limit value set by the limiter 38 is Since the variable processing unit 53 gradually increases or decreases, the assist correction current can be changed smoothly. Therefore, the operation of the electric motor 10 can be made smooth.
- the time when the limit value set by the limiter 38 is gradually increased from 0 Nm to the upper limit by the limiter variable processing unit 53 and the time when the limit value is gradually decreased from the upper limit to 0 Nm may be the same time or different times.
- the switcher 52 shown in FIG. 5 and the limiter variable processing unit 53 shown in FIG. 6 may be used in combination. Specifically, when the execution condition is switched from not established to established in the execution condition determination unit, the limit value set by the limiter 38 is gradually increased from 0 Nm to the upper limit value in the limiter variable processing unit 53 while the execution condition is changed. When the execution condition is switched from established to not established in the condition determining unit, the switch 52 may add 0 A to the assist base current. Further, when the execution condition is changed from not established to established in the execution condition determining unit, the assist correction current is added to the assist base current by the switch 52, while the execution condition determining unit is changed from established to not established. When the switching is performed, the limit value set by the limiter 38 in the limiter variable processing unit 53 may be gradually decreased from the upper limit value to 0 Nm.
