A control device of a dynamometer system includes a mechanical loss arithmetic unit that generates a loss compensation signal corresponding to loss torque generated in a dynamometer body in a state where a load is connected, on the basis of an angular velocity detection signal, a characteristic vibration suppression control circuit that generates a compensation signal in order to suppress a characteristic vibration of a swinging element, and a torque current command signal generating unit that generates a torque current command signal by subtracting the compensation signal from an upper level torque command signal. The characteristic vibration suppression control circuit is provided with a normative model arithmetic unit, deviation compensator, model input generating unit, and differential compensator that generates a correction signal by subjecting a torque signal obtained by the normative model arithmetic unit to a differential operation.

A vehicle testing device including a cooling device, which is capable of freely selecting a part to be cooled and a wind direction in accordance with a purpose of a test is provided. The vehicle testing device that tests a test piece that is a vehicle or a part of the vehicle includes a rotating body on which the test piece is placed, and a cooling device that sends air from a side of the test piece to at least a part of the test piece in order to cool the test piece placed on the rotating body.

One example is test system for testing the propulsion system(s) of vehicles. The test system includes a retention fixture, a linking device, a test logic, a measurement device and a result logic. The retention fixture is for rigidly mounting first and second vehicles to the retention fixture. The linking device links propulsion systems of the first and second vehicles so that the propulsion systems operate a different rates. The test logic subjects the second vehicle's propulsion system to a propulsion test. The measurement device measures at least one parameter associated with the propulsion system of the first vehicle while the first vehicle is subjected to the propulsion test. The result logic determines if the first vehicle under test passed the propulsion test based, in part, on the at least one parameter and generates an indication if the first vehicle passed or failed the propulsion test.

A vehicle inspection apparatus includes: an exciter roller (3) configured to apply vibration to a vehicle (6); a control device 5 configured to control the exciter roller (3); and a vibration setting unit (the control device (5)) configured to set a vibration that is input to a wheel (7) of the vehicle (6) when abnormal noise generated in the vehicle (6) is detected. The control device (5) provides a range of vibrations including the vibration set by the vibration setting unit and applies the range of vibrations to the vehicle (6).

The disclosure provides a position changing device capable of reducing the size of the entire device in a plane. A position changing device (30) includes four pulley mechanisms (40). In the pulley mechanism (40), a toothed belt (45) is wound around a driving pulley (41) and a driven pulley (43), and is held between the driving pulley (41) and an idler roller (42) by the idler roller (42) and held between the driven pulley (43) and an idler roller (44) by the idler roller (44), and when the driving pulley (41) is driven by a driving mechanism (46), the position of a movable base plate (31) is changed.

Provided are a vehicle inspection system and a vehicle inspection method that can align a vehicle with a constant location of a bench testing machine. The present invention comprises: a bench testing machine that rotatably supports wheels of a vehicle, using rollers that are provided for each of the wheels; and a monitor device that is positioned in a fixed location with regard to the bench testing machine and displays, toward a camera, an image resembling an exterior environment, wherein the bench testing machine has a location adjustment device (turning mechanism, test bench control device) that adjusts the location of the vehicle in the vehicle width direction such that the relative location of the camera in the vehicle width direction with regard to the monitor device is constant.

A vehicle securing apparatus is provided for pulling and securing a test vehicle provided to a vehicle testing device. The column stands on the pedestal. The vehicle securing apparatus includes a column, a traveling and rotating part, and a pedestal. The traveling and rotating part is structured to be coupled with a chain for pulling the test vehicle, and arranged coaxially with the column, and structured to travel vertically and rotate horizontally. The pedestal is structured to be attached to an arbitrary portion of a slide rail of the vehicle testing device.

The present invention relates to a method of positioning at least one wheel support of a vehicle dynamometer in relation to the position of a wheel in the longitudinal direction of a vehicle standing on the vehicle dynamometer. The wheel support is positioned using a drive unit for adjusting the position of the wheel support. The positioning takes place with a vehicle located on the vehicle dynamometer, wherein the vehicle is held in place during the positioning at least in relation to its longitudinal direction. The positioning of the wheel support takes place as a function of a variable that represents a three to be applied by the drive unit and/or a torque to be applied by the drive unit and/or the power consumption of the drive unit and/or the work done by the drive unit when the wheel support is moved along a defined distance when a specific movement profile of the wheel support is achieved during movement in a direction corresponding to the longitudinal direction of a vehicle standing on the vehicle dynamometer.
