になる。The performance of a power system refers to how efficiently the power from the engine is transmitted to the ground via the power transmission system to move and stop the vehicle.
This is usually acceleration/braking performance and maximum speed. Items such as maximum traction force (hill climbing) performance are subject to evaluation. Also, what is the performance of the suspension system? How to suppress vehicle body movement (vibration) while driving. Spring characteristics are the key to improving riding comfort.

．データがかなり異なったものになって，採取データの
信頼性が損なわれる。In the case of power plants, these performance evaluations are based on how many seconds it takes to cover a predetermined distance, for example, 200 meters, on a flat paved road, generally about 1 to 2 km in length, called a fixed test site, in terms of acceleration, and in terms of maximum speed. Regarding the maximum traction force, how many km/h it can reach, how much traction it can pull, and the braking. This evaluates how many meters the vehicle can stop at a predetermined speed. Therefore, there is a difference between rainy or snowy weather when the road surface is prone to slipping and other times. The data will be significantly different and the reliability of the collected data will be compromised.

いる。Also, what is the performance of the suspension system? In general, protrusions called obstacle plates are placed on the above-mentioned fixed test site or on the paved road surface, and tests called single obstacle plate crossing and continuous obstacle plate crossing are conducted to determine the speed at which the obstacle plate is approached, the magnitude of vehicle body sway, and control. The degree of hand seat acceleration and other factors are measured to determine whether ride comfort is good or bad.

が損なわれるという問題があった。However, the said obstacle plate... It is a heavy item and difficult to secure to a paved road surface. Also, in tests with high vehicle speeds. The obstacle plate was displaced by the impact when it collided with the track of the test vehicle. There was a problem in that it required a lot of effort to rearrange. Furthermore, performance evaluation of suspension systems utilizes natural terrain. Referred to as a driving test on corrugated ground or rocky ground, this test collects the same data as the above-mentioned ground test, evaluates the heat generating capacity of oil dampers, and evaluates strength and durability, and evaluates practicality in a more realistic manner. However, this is also a test against natural terrain,
Even data collected at the same testing site. In case of heavy rain or heavy snow. Since the course (topography) was changed, there was a problem in that the reliability of the collected data was lost.

Additionally, vehicle maneuverability evaluation tests can be conducted without being affected by the weather or the topography of the test site. Another object of the present invention is to provide a vehicle maneuverability evaluation test device that can improve the reliability of collected data.

好な性能を有することになる。(a) Single Obstacle Board Crossing Test Each vibration excitation pressure actuator (4) and each support roller (3) are positioned directly below the wheels of the test vehicle (1). In addition, in this vehicle maneuverability evaluation test device, the number of vibration actuators (4) is 8 on each side, 16 in total, and the reason for this is largely related to this overpass test. That is,
This type of test vehicle (1) is mostly composed of 4 to 7 wheels on each side, and if there are 8 wheels on each side, considering one of the ten α, this type of test vehicle (1) Compatible with most models. Here, to simplify the explanation, a test vehicle (1) with six wheels on one side and a spacing of lm between the wheels is used when an obstacle of 20 cm height is Fi. (protrusion) at a vehicle speed of 1 Bkm/h will be explained. The above data is input into the control device (16) of the control room (14). Each pressure device in the hydraulic chamber (20) is
When the test is started with a stand-up command from the control device (16), the vibration hydraulic actuator (4) directly below the I wheel is operated in the extension direction to push the first wheel up by 20 cm. At a vehicle speed of 18 km/h, the time it takes for 6 wheels to travel 5 meters is 1 second, so the 2nd wheel, 3rd wheel, 4th wheel, and 5th wheel are pushed up 20 cm at 0.2 second intervals. , the 6th wheel will be pushed up 20cm in 1 second. Then,
Vehicle speed 1B on a fixed ground test road with 20cm protrusions
It is possible to obtain the same vibration of the vehicle body as when passing at km/h. At this time. On the test vehicle (1), data such as pitch and roll angles of the vehicle body, angular velocity, displacement of the center of gravity on the sprung mass, and acceleration of the driver's seat can be obtained from onboard measuring instruments such as gyros and accelerometers, and this data is recorded by a data recording device ( l5) and record it here. Also, the hydraulic actuator for vibration (4) {!
! The data of II also measures the excitation displacement, speed, and load (hydraulic pressure), and sends this to the data recording device (15), where it is recorded. It should be noted that the suspension system will have better performance if the amount of vibration and acceleration of the sprung mass of the vehicle body is smaller in response to the same vibration input.

Excite the wheels of the In this way, the same vehicle body vibration as when driving the test vehicle (1) on natural terrain can be obtained.
