ADAS virtual development and test system

Abstract

The invention provides an ADAS virtual development and test system, which comprises an acquisition unit used for acquiring a real traffic environment, a virtual driving unit used for simulating real driving behaviors, a real-time simulation unit used for simulating a real or virtual environment and vehicle driving attitude, and a display unit used for displaying information. The ADAS virtual development and test system regards a real traffic scene which is shot by a real vehicle in advance and projected to an annular screen as input of road information of a real-time simulation machine, can reflect the driving behaviors of a driver in the real environment, comprises various kinds of interference, noise and sudden incidents in the real environment, so that the assessment and development of an ADAS product are more credible, reliable and true; and through the assessment of comparing test results of the tested ADAS product with a standard algorithm stored in the real-time simulation machine, the ADAS virtual development and test system can obtain digital assessment results while testing is performed.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an ADAS virtual development and testing system. Background technique [0002] In recent years, with the development of my country's economy and the improvement of people's living standards, cars are no longer out of reach in people's eyes. It is very common for ordinary families to own one or more cars, but with the rapid increase in the number of cars However, the development speed of my country's urban traffic construction is far behind the growth rate of automobiles. Therefore, the safety of automobiles has become the most important part of automobile technology research. In order to ensure the driving safety of drivers and reduce the In case of injury in dangerous situations, driver assistance systems emerge as the times require. Advanced Driver Assistance Systems (ADAS) uses various sensors installed on the car to collect environmental data inside and outside the car in time t...

AI Technical Summary

Problems solved by technology

At present, major automobile manufacturers mainly use the actual road test method to test the performance of ADAS products. Although the actual road test can provide a real traffic environment, the risk factor of the test process is very high, and the road environment and experimental conditions provided are extremely limited.

Moreover, ADAS systems usually have multiple on-board control systems working together, such as lane departure warning, front emergency braking, blind spot alarm, etc. The system functions are complex, so the actual road test workload is huge, and it is difficult to meet the current increasingly shortened automotive product development. cycle requirements

[0004] In addition, the ADAS system has very strict requirements on real-time performance, and needs to exchange data with different types of sensors in real time (such as cameras, laser radars, millimeter-wave radars, vehicle CAN buses, GPS, etc.), and due to the highly complex interaction between various systems Therefore, a new method for testing and evaluating ADAS products is needed
