| 1. A testing apparatus for a steering apparatus including a torque sensor which detects a steering torque, a steering actuator
which applies a steering force to a steering mechanism, and a controller which controls the steering actuator based on an
output of the torque sensor, the testing apparatus comprising:
a test signal generating unit which generates a test signal of a sine sweep waveform simulating an output signal of the torque
sensor;
a driving signal generating unit which generates a driving signal according to the test signal generated by the test signal
generating unit and supplies the driving signal to the steering actuator; and
a torque signal monitoring unit which acquires a torque signal outputted from the torque sensor.
