Description

  The present invention relates to a vehicular travel test apparatus capable of automatically performing a travel test on a two-wheeled vehicle using a chassis dynamo or the like.

  Conventionally, this type of vehicle running test apparatus is installed on the floor around the vehicle and twists the accelerator grip or the like using a rod-like attachment or the like that is connected to the accelerator grip or the like that is the operation target portion of the vehicle. Then, a running test of the vehicle was performed (for example, Patent Document 1).

  Thereby, since it can operate | move instead of a person, the driving test apparatus for vehicles which can aim at labor saving was provided.

However, ATV (All Terrain Vehicle), whose demand has been increasing in recent years, is strongly subject to reaction from the front, rear, left and right during driving, and it is difficult to control acceleration / deceleration of ATV with a grip type accelerator, so there is a risk of running away. Unlike the conventional type of twisting accelerator, it is driven by the type of accelerator that turns the lever.
For this reason, since the conventional vehicle running test apparatus could not operate this lever and the running test could not be performed, the running test was performed by connecting the wire that was disassembled and pulled out from the ATV accelerator part. It took time and labor, and there was a possibility that trouble would occur in ATV by this decomposition.
