Problems to be disclosed by the invention

When conducting an automated driving test of a vehicle in a room, use a rope to secure the vehicle so that it does not move. But you have to rotate the tires. Moreover, since the handle is turned, it is necessary to be able to change the direction from side to side.

Means for solving the problem

The position does not move, but tires and the like are placed on a plurality of spherical bodies that rotate in all directions.

This embodiment is shown in FIG.
The four tires A of the automobile were placed on a platform B on which a tire or the like consisting of a plurality of four freely rotatable balls is placed. Next, the rope D was attached to the base B on which an automobile, a tire, etc. are placed, and each rope was strongly pulled and tied to the anchor C.
And when I started the car engine and rotated the tires, the tires rolled on multiple balls. Next, when I turned the handlebar, the handlebar turned without any resistance.

This embodiment is shown in FIG.
Load is added to the rotation of the tires to allow the car to climb a hill. Also, when the steering wheel is turned, a load is applied to the rotation of the tire. FIG. 2 shows a device for varying the load when the vehicle actually runs, climbs a hill, and turns the steering wheel. The controller E receives the operation command of the experiment from the control cable G by CAN. Alternatively, the instruction is given from the keyboard F. Then, an instruction to apply a brake from the controller E goes to the brake in the holding body, and the rotation of the spherical body becomes heavy. Lighten the load when it becomes flat. The height J of the table on which the tires and the like were placed was 150 mm, and the width K was 1200 mm.

This embodiment is shown in FIG.
In the second embodiment, the load is applied by bringing the brake shoe into contact with the spherical body, but in this method, the left and right sides of the tire or the like are sandwiched by two rollers, and an electric brake is attached to these rollers to control the load from the outside. To do. By reversing the electric current, the electric brake also functions as a motor and can accelerate an automobile or the like.

This example is shown in FIG.
Sensors such as cameras and radars are installed in vehicles to monitor the front, side, diagonal direction and rear. At this time, it is a device for experimenting how to attach and move the sensor when the vehicle climbs a slope and shifts horizontally. It also serves as a device for actually experimenting with changes in power.
A stand on which a tire or the like is placed is attached to the movable body N, and the movable body movable joint portion is used as an axis to incline vertically. In addition, you may incline to right and left. In addition, this device may be equipped with a device for raining, a mechanism for darkening, brightening, and changing the temperature.

If a vehicle is equipped with a collision prevention mechanism or an automatic driving mechanism, it is necessary to test about 300,000 km before sales. In this case, it is important to test in the room before testing on the test track or on the actual road.
At this time, the platform on which the tires are placed becomes an important device.
