Test method and test system of vehicle braking system

Abstract

The embodiment of the invention discloses a test method and a test system for a vehicle braking system. The method comprises the steps that the initial position of an obstacle model and the position of a distance detector are determined, and the distance detector is used for detecting the distance between a detected vehicle and the distance detector; determining a target distance; wherein when the distance between the detected vehicle and the collision point is a target distance, the obstacle model moves from the initial position to the collision point in a first motion mode, and the detected vehicle travels to the collision point in a second motion mode, so that the obstacle model and the detected vehicle reach the collision point at the same time; the distance detector is used for detecting the distance between the detected vehicle and the distance detector; when the distance between the detected vehicle and the distance detector is the target distance, the obstacle model is controlled to move from the initial position in a first movement mode, and the detected vehicle is controlled to run in a second movement mode; and when the obstacle model and the tested vehicle arrive at the collision point, obtaining a braking system test result so as to simplify the test process of the vehicle braking system.

Description

technical field [0001] The present invention relates to the field of vehicles, in particular to a testing method and testing system of a vehicle braking system. Background technique [0002] With the development of vehicle intelligent technology, the automatic emergency braking system (AEB) has become an important function to improve the driving safety of the vehicle, and it has been more and more widely configured in the vehicle. [0003] At present, AEB is usually tested in the scenario where obstacles such as pedestrians, bicycles, and battery cars cross the front of the vehicle. The AEB test method is as follows: control the vehicle equipped with AEB to drive to the position of the obstacle in front of the vehicle at different speeds, test the braking and early warning of the vehicle without human intervention, and test the AEB configured on the vehicle. Usually the obstacle is replaced by the obstacle model of a person or a car, and the obstacle model is controlled to ...

Problems solved by technology

[0005] However, when the AEB test is performed using the above method, the above two base stations need to be installed, which makes the test process of the vehicle braking system more complicated
