Testing system and testing method

Abstract

The embodiment of the invention relates to the field of driving testing systems, and discloses a testing method and a testing system. The testing system comprises a traffic simulating module, an interface interaction simulating module and a measured object, wherein the traffic simulating module is used for simulating a traffic environment in the running process of a tested vehicle and simulating the tested vehicle; the interface interaction simulating module extracts a sensor signal of the tested vehicle from traffic information and scrambles the sensor signal with environmental information; the measured object is used for determining a next control instruction of the tested vehicle according to the scrambled sensor signal of the tested vehicle and transmitting the next control instructionto the traffic simulating module. Through the testing method and the testing system, when an automatic driving function of the vehicle is tested, influence of the environment on a vehicle sensor is considered, and weather conditions and disturbing vehicle behaviors which are closer to the reality are set, so that a tested driving scene is more real, and the automatic driving function of the vehicle is conveniently verified.

Description

technical field [0001] The embodiments of the present invention relate to the field of driving system testing, in particular to a testing system and testing method. Background technique [0002] As people's demand for vehicle functions increases, more and more vehicle manufacturers provide vehicles with automatic driving functions, providing convenience for users to drive vehicles. However, in the development process of the automatic driving controller, it is necessary to test its driving function and safety function. The traditional test method is: install it on a real vehicle for testing, and cooperate with relevant real interfering vehicles and traffic participant models, such as dummy , false obstacles, etc., to achieve standard working condition testing. The advantage of this method is that the environment under test is completely real, and the test accuracy of the standard working condition is high, but there are also some problems, such as: the real vehicle and the m...

Problems solved by technology

[0004] The inventors found that there are at least the following problems in the prior art: Although the existing HIL technology can conveniently complete the development and verification of the automatic driving control strategy, it only has signal-level data interaction

The verification of the real automatic driving function also needs to consider the influence of weather and environment on the sensor, the characteristics of the wireless channel, and the driver's driving experience. Complex and changeable driving scene requirements
