The invention relates to an automatic driving simulation software co-simulation test method and system, and relates to the technical field of automatic driving test, and the method comprises the steps that: a vehicle in-loop module and a simulation driving module send test scene information to a Broker module based on an MQTT protocol; the driving simulation module obtains test scene information from the Broker module, changes the driving behavior of a virtual traffic vehicle of the vehicle in the ring module according to the test scene information, and sends the changed driving behavior information to the Broker module; the vehicle in-the-loop module obtains the driving behavior information from the Broker module, and imports the driving behavior information into the test scene information to obtain new test scene information; and automatic driving test is performed on the to-be-tested automatic driving vehicle based on the new test scene information. According to the invention, the complexity of a communication structure and the communication cost are reduced, the expansion of the number of nodes is more flexible and simpler, and the dynamic IP communication requirement is met.
Description
technical field [0001] The present application relates to the technical field of automatic driving testing, in particular to a method and system for co-simulation testing of automatic driving simulation software. Background technique [0002] Autonomous driving simulation software is a simulation technology gradually developed with the evolution of autonomous driving technology, and it plays an increasingly important role in the process of autonomous driving vehicles. For self-driving cars, it is generally believed that each self-driving system needs 16 billion kilometers of driving data to complete the performance test of self-driving cars. However, if a fleet of 1,000 self-driving test vehicles is configured, it will cost about It takes about 50 years to complete the mileage test of 16 billion kilometers. It can be seen that it is not realistic to conduct the performance test of the self-driving car through the actual road test, which requires a lot of time and cost. There...
