Device and method for testing emergency braking function of autonomous vehicle

Abstract

The invention discloses a device for testing the emergency braking function of an autonomous vehicle through combination of virtuality and reality, and the device comprises a positioning module which comprises an antenna and an inertia measurement unit, and a scene design module comprising a map storage unit, an autonomous vehicle management unit, a virtual target vehicle management unit and a scene test evaluation calculation unit; and once the autonomous vehicle runs to reach a triggering condition, the relative position and the movement track of the virtual target vehicle are planned on the map, and motion information of the virtual target vehicle is implanted into the autonomous vehicle by means of protocol. A scene test evaluation calculation unit compares the relationship between the vehicle head position of the autonomous vehicle and the vehicle tail position of the virtual target vehicle, if the vehicle head position of the autonomous vehicle and the vehicle tail position of the virtual target vehicle are not overlapped, the test is passed, and otherwise, the collision is indicated. The emergency braking function of the autonomous vehicle is tested in a virtuality and reality combined mode, and the device has the advantages of being low in cost, high in efficiency and high in success rate.

Description

technical field [0001] The invention relates to the technical field of automobile safety detection, in particular to a test method for testing the emergency braking function of an automatic driving vehicle in the China New Car Assessment Program (CNCAP). More specifically, the present invention relates to a device and method for testing the emergency braking function of an autonomous vehicle. Background technique [0002] With the continuous development of autonomous driving technology, people have higher and higher requirements for vehicle intelligence and safety performance, especially for high-level autonomous vehicles. In the prior art, testing equipment such as a flexible model car, a control chassis car and a driving robot are usually used to complete the whole test. At present, the test equipment that meets the standard requirements is imported from abroad, with a set cost of about 30 million yuan; and the installation and commissioning of the test equipment takes a ...

Problems solved by technology

At present, the test equipment that meets the standard requirements is imported from abroad, with a set cost of about 30 million yuan; and the installation and commissioning of the test equipment takes a long time, the whole test takes about 10 minutes, but the preparation time in the early stage takes 4-5 hours, which is time-consuming People cannot meet the needs of batch testing; due to the accuracy limitation of testing equipment, the success rate of each test meeting the requirements is only 80%
