Abstract
The testing apparatus tests 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 apparatus includes 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.
