V2V-based test method and test system for vehicle emergency brake early warning system

Abstract

The invention relates to the field of V2V equipment testing, in particular to a V2V-based test method and test system for a vehicle emergency braking early warning system. The test method comprises the following steps: constructing a test case which at least comprises test road conditions of a straight lane, a curve and a ramp of a single lane and test road conditions of a straight lane and a curve of two adjacent lanes; driving the target vehicle and the background vehicle on the test road condition according to the test case, recording early warning information sent by the target vehicle, and recording running time information of the target vehicle and the background vehicle; and analyzing whether the early warning information meets a test index or not according to the runtime information. The test system simulates a test scene through the test case construction module, and is wide in coverage and high in pertinence; the running time information of the target vehicle and the background vehicle is obtained through the test module, the synchronism is high, and the accuracy is high; and a test index is generated through the first test module. On the whole, according to the test method and system, the simulated test scene is complete, the key performance evaluation indexes of the system are mature, and the test reliability is high.

Description

technical field [0001] The invention relates to the field of V2V equipment testing, in particular to a testing method and testing system of a V2V-based vehicle emergency brake warning system. Background technique [0002] V2X communication (Vehicle to Everything communication, the connection between the vehicle and everything) belongs to a category of the Internet of Things. V2X is a communication system, which is specially used to connect the car with the surrounding environment. It is mostly used for intelligent driving, and the first task of realizing intelligent driving is networking. Apart from the various sensors and cameras used in intelligent driving, the Internet of Vehicles can also be considered as an extension of sensing technology. [0003] V2V communication (vehicle-to-vehicle communication, communication between vehicles) refers to wireless-based data transmission between motor vehicles, sending vehicle position and speed information to other vehicles through...

Problems solved by technology

However, a large amount of research work is mainly aimed at the development of the basic functions of the product, and the overall technical requirements of the test standard are relatively rough.

As a real-vehicle test and verification scheme for the vehicle emergency brake warning system before the product goes on sale, the current simulated test scenarios are incomplete and cannot cover various complex positional relationships and speed differences between vehicles, and the built test system is not perfect. Various runtime information (such as positioning, speed, acceleration, etc.) of the vehicle cannot be accurately obtained in real time, and the key performance evaluation indicators of the system are immature, so it is impossible to accurately evaluate the V2V performance of the test vehicle, resulting in the overall low reliability of the test
