A bumper for a mobile platform of a guided test platform includes a first end, a second end residing opposite the first end, a first surface extending between the first and second ends, and a second surface extending between the first and second ends and residing opposite the first surface. The bumper defines a ramp structure extending between the bumper first end and the bumper second end. The ramp structure is structured to guide a wheel of a vehicle in a direction away from the first surface as the wheel moves along the second surface in a direction from the bumper first end toward the bumper second end.

The disclosure provides an excitation device, in which a vibration in a front-rear direction generated by excitation actuators is input to second bars via excitation arms and excitation shafts, and four wheels are vibrated by the vibrations of the second bars, so as to rotate a vehicle on at least one of a yaw axis, a pitch axis, and a roll axis. A controller controls a phrase and an amplitude of the operation of each of four piston rods of four excitation actuators.

A pedal actuator (41) of an automatic vehicle driving device (1) is supported by a pedal actuator support (51) by mounting a pedal actuator support bracket (61) to the pedal actuator support (51) and fixing the pedal actuator support bracket (61) with a lock pin (67). In the automatic vehicle driving device (1), when mounting the pedal actuator support bracket (61) to the pedal actuator support (51), by connection between a support-side connector (53) and a bracket-side connector (63), electrical connection between the pedal actuator support (51) and the pedal actuator support bracket (61) is also completed.

A transmission actuator unit (131) configured by combination of a selecting actuator (133) and a shifting actuator (134) is mounted on an upper surface of a connection box unit (101). A connection box frame (102) is slidably supported along guide rails (20) between a pair of main beams (15a) of a slanting frame (11). By sliding the connection box unit (101), it is possible to adjust a height position of the transmission actuator unit (131) to a height position of a shift lever.

A transmission actuator unit (131) is fixed on a actuator support plate (105) of a connection box unit (101) through a pair of lock mechanisms (143). A pair of grommets (121), with which lock pins (144) are engaged, are provided at both of a front side and a rear side of the actuator support plate (105). Then, the transmission actuator unit (131) can be selectively mounted on the actuator support plate (105) in either of two attitudes that are reversed 180 degrees according to vehicle types. Since a base plate of the transmission actuator unit (131) is mounted on the actuator support plate (105) settled in a horizontal attitude, rigidity of support of the transmission actuator unit (131) and the actuator support plate (105) is high.

A pedal actuator support bracket (61C) is provided at a front end portion of a frame (11) supported at a driver's seat of a vehicle. An actuator housing (78) is provided so that a base end side of the actuator housing (78) is supported by the pedal actuator support bracket (61C) so as to be able to pivot upward and downward relative to the pedal actuator support bracket (61C). A rack shaft (80) protrudes from a top end side of the actuator housing (78) and moves forward and backward along a longitudinal direction of the actuator housing (78). A pivotal plate (87) is connected to a top end of the rack shaft (80) so as to be able to pivot upward and downward and placed on a pressing surface of a clutch pedal (47) so as to overlap this pressing surface and fixed to the clutch pedal (47).

A method of evaluating integrated running energy of a vehicle in a wind tunnel may include estimating change in fuel efficiency according to change of vehicle parts thereby facilitating precise measurement of running energy.

In a vehicle action simulation method according to the present invention, a behavior of an actual vehicle during travel is predicted, and an attitude of a tire and a rotational speed of a rotary drum are changed to reproduce a transient change in a tire attitude that occurs during the travel of the actual vehicle on the tire while the predicted behavior of the actual vehicle during travel is reflected, stress applied to the tire in contact with the rotary drum of a tire ground contact characteristic measuring portion is measured, tire ground contact characteristics are calculated, the behavior of the actual vehicle during travel is predicted while vehicle characteristics predicted from the tire ground contact characteristics are reflected, and the prediction, the reproduction, the measurement of stress, and the calculation are performed in parallel.

A safety fence for a vehicle testing device includes a fixed fence part structured to be arranged substantially in parallel with a wheel of a test vehicle, wherein the test vehicle is placed on a roller exposed through a roller opening of a pit cover. A first foldable fence part is attached to an end portion of the fixed fence part, and structured to swing outwardly of the fixed fence part. A second foldable fence part is attached to an end portion of the first foldable fence part, and structured to swing outwardly of the first foldable fence part. A third foldable fence part attached to a lower end portion of the fixed fence part, and structured to be arranged in parallel with the fixed fence part.
