Vehicle performance inspection apparatus and vehicle performance inspection method

A vehicle performance inspection apparatus for individually evaluating the operational states of an LSD control and a TRC control, said apparatus comprising:

• left and right pairs of parallel receptive support rollers, one of the receptive support rollers of each pair being a driving receptive support roller and the other being a driven receptive support roller, for receiving and supporting the left and right wheels of the driving section of a vehicle,
• main clutch means for connecting or disconnecting the left and right driving receptive support rollers,
• main rotational frequency detecting means for detecting the rotational frequencies of the driving receptive support rollers,
• left and right motors that can be connected to or disconnected from the left and right driving receptive support rollers through left and right clutch means and can also act as voltage generating means as loads,
• left and right torque detecting means for detecting the driving torques between the left and right voltage generating means as loads and the driving receptive support rollers associated therewith,
• left and right rotation detecting rollers that can subordinatively be rotated by causing them to be forcibly brought into contact with the left and right wheels received and supported on the left and right driving receptive support rollers and driven receptive support rollers, and
• left and right rotational frequency detecting means for detecting the rotational frequencies of the wheels through said rotation detecting rollers.

A vehicle performance inspection apparatus for individually evaluating the operational states and performance of an ABS control, an LSD Control and a TRC control, said apparatus comprising:

• main clutch means for connecting or disconnecting the left and right driving receptive support rollers,
• main rotational frequency detecting means for detecting the rotational frequencies of the driving receptive support rollers,
• left and right motors that can be connected to or disconnected from the left and right driving receptive support rollers through clutch means and can also act as voltage generating means as loads,
• left and right first torque detecting means for detecting the driving torques between the left and right voltage generating means as loads and the driving receptive support rollers associated therewith,
• left and right rotation detecting rollers that can subordinatively be rotated by causing them to be forcibly brought into contact with the left and right wheels received and supported on the left and right driving receptive support rollers and driven receptive support rollers,
• left and right rotational frequency detecting means for detecting the rotational frequencies of the left and right wheels through said left and right rotation detecting rollers,
• left and right inertial rotating means that can be connected to or disconnected from said left and right rotation detecting rollers through left and right change-over clutch means and can be rotated inertially by the above subordinative rotation, and
• left and right second torque detecting means for detecting the driving torques between the rotation detecting rollers for said left and right wheels and the inertial rotating means associated with said rotation detecting rollers.
