ABSTRACT:
A running control function of a motorcar is inspected on an inspecting apparatus which is provided with rolls for mounting thereon each of wheels of the motorcar. The control function operates to control rotational speeds of wheels depending on a difference in rotational speed between front and rear wheels or right and left wheels of the motorcar. The motorcar is caused to run in a condition in which each of the wheels of the motorcar is mounted on each of the rolls. When a rotational speed of a first roll for mounting thereon one of front and rear wheels or one of right and left wheels and a rotational speed of a second roll for mounting thereon the other of the front and rear wheels or the other of the right and left wheels have both increased to a predetermined speed, the first roll is decelerated. A judgement is made as to whether the running control function is acceptable or not based on a correlation between a change in rotational speed of the first roll and a change in rotational speed of the second roll during the step of deceleration.
