Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings. It should be understood that the following embodiments are used to illustrate the present invention, but not to limit the present invention.
[0021] Such as Figure 1-3 As shown, a wheel active retraction system of a dummy car on an unmanned driving system test platform, the system includes a retraction mechanism fixed on the frame of the dummy car, a pneumatic control system and a high-pressure supply mechanism, the retraction mechanism includes wheels 1, The wheel 1 is a wide tire of an assembly, and both sides of the wheel 1 are installed on the load-bearing arms 2 with bolts, and the other ends of the two load-bearing arms 2 are fixedly connected with the middle load-bearing shaft 5, and the middle load-bearing shaft Both ends of 5 are provided with bearings 4 and are fixed on the vehicle frame of the fake car by bearings 4 and flange 3, and the middle bea...

The invention discloses an active wheel retraction system of a dummy car on an unmanned driving system test platform, comprising: a retraction mechanism, a pneumatic control system and a high-pressure supply mechanism; The load-bearing shaft forms a fixed whole, which can make the wheel and the middle load-bearing shaft rotate around the axis together. The pneumatic control system adjusts the telescopic state of the wheel through a double-acting cylinder, and the high-pressure supply mechanism inflates the pneumatic control system. The invention can actively control the telescopic state of the wheels, so that the fake car on the test platform can not only have better obstacle-crossing driving performance during the test of the unmanned driving system, but also can reduce the fake car on the test platform when it collides with other real test vehicles. The height is to avoid direct collision impact and protect the core components of the unmanned driving system.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a wheel active retraction system of a fake car on an unmanned driving system test platform. Background technique [0002] Unmanned driving system test platform vehicles generally use a simplified body model to simulate the driving state of the real vehicle, but once the traditional test platform vehicle collides with the real test vehicle, it is easy to cause damage to the core components of the unmanned driving system. [0003] With the development of unmanned driving technology, the method of integrating the driving system on the chassis and simplifying the body with a detachable soft structure to form a test platform fake car has begun to attract people's attention. Contents of the invention [0004] In view of this, the present invention provides a wheel active retraction system of the dummy vehicle on the test platform of the unmanned driving system, which enables the ...
