Abstract

The invention discloses a wheel active retraction system of an unmanned driving system test platform dummy vehicle. The wheel active retraction system comprises a retraction mechanism, a pneumatic control system and a high-pressure supply mechanism, wherein a force bearing arm, a rocker arm and a middle force bearing shaft in the retraction mechanism form a fixed whole, wheels and the middle forcebearing shaft can rotate around the axis together, the pneumatic control system adjusts telescopic states of the wheels by means of a double-acting cylinder, and the high-pressure supply mechanism inflates the pneumatic control system. According to the wheel active retraction system, wheel telescoping state control can be carried out actively, so that the test platform dummy vehicle has good obstacle crossing driving performance when an unmanned driving system test is conducted, and the height of the test platform dummy vehicle can be reduced when the test platform dummy vehicle collides withother test real vehicles, thereby avoiding direct collision impact and protecting 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 ...
