向かって走行する。[Prior Art] In general, in a lobe-traction type vehicle collision test device, it is necessary to avoid making large-scale modifications to the towed vehicle, and on the other hand, it is necessary to avoid making large-scale modifications to the towed vehicle. It is necessary to disconnect the towed vehicle. Therefore, in normal collision test equipment, the towing rope and the vehicle are rarely directly connected, and a towing trolley (called a dolly) is often interposed between the two. Therefore,
To illustrate these relationships in a relatively common example, a lobe clamp mechanism at the bottom of the towing truck grips the towing lobe running below the truck running groove rail, while a lobe clamp mechanism at the top of the truck grips the towed lobe. There is a latch-like structure that hooks the towing bracket attached to the vehicle. Then, when you reach the disconnection point, you will see a disconnection installed on the ground! By position a, both the lobe clamp 81611 and the latch-like mechanism are released, and the vehicle then coasts independently toward the collision target.

置は当然のことながら無人で作動させる必要がある。On the other hand, there are various purposes for vehicle experiment equipment, and there are some that allow a vehicle to collide head-on with a fixed object, completely damaging the vehicle on the spot, and others that allow vehicles to collide head-on with a fixed object, completely damaging the vehicle on the spot. There is also a risk that the test vehicle may run out of control after a collision. Therefore, a vehicle braking system after a collision is essential for the intruder's equipment, and even with the former equipment, there are cases where the test vehicle is stopped in front of the collision object during a preliminary test run. Yes, vehicular V1 motion equipment is required in almost every facility. Naturally, this device must be operated unattended.
ところで、従来、車輌衝突実験装置に於ける無人実車制
動方法あるいは装置の一実施例として、第４図で示すよ
うな一実施例があった。Incidentally, in the past, there has been an example as shown in FIG. 4 as an example of an unmanned vehicle braking method or device in a vehicle collision test apparatus.

圧制御回路により作動してブレーキベタル６を踏み込む
アクチュエータである。An actuator 5 is provided in front of the brake pedal 6 of the vehicle and is actuated by a pneumatic control circuit to depress the brake pedal 6.

人の被試験車輌にブレーキがかかる。In the above configuration, when the vehicle collides with the object, the steel ball 1 falls from the receiver 4 due to the impact of the collision, and the valve body 2
is switched. Then, the actuator 5 is actuated by the pressure medium, and its suppressing member 7 depresses the brake pedal 6 of the vehicle. As a result, the brakes are applied to the unmanned test vehicle released from the tow truck.

乏しかった。However, this embodiment had the following problems. In other words, the shock-sensing switch method has the disadvantages of false detection due to the vibration of the vehicle during traction acceleration, and the possibility of not detecting it if the shock received by the vehicle under test is unexpectedly small. It is extremely difficult to set the value of the shock to be applied, and this sensing mechanism alone lacks reliability.

A flexible compressed air pipe filled with compressed air is extended from the M vehicle, a blind plug is attached to the tip of the compressed air pipe, and the blind plug is connected or attached to the towing truck, and the towing truck and the vehicle under test are separated. By doing so, the blind stopper is automatically pulled away from the tip of the compressed air pipe, and the pressure inside the compressed air pipe decreases, and the braking system of the vehicle is activated via a pneumatic or electric circuit that detects this decrease in pressure. The purpose is to operate the actuator that operates the .
