Abstract

For checking whether a physical layer of a FlexRay bus system or a FlexRay bus node meets the consistency requirement of a FlexRay bus protocol, the invention provides a FlexRay bus physical layer test method combining a local test method with a collaborative test method. An upper computer and several test FlexRay nodes are used for respectively forming one test FlexRay network and one under-test FlexRay network through a USB (Universal Serial Bus)-to-FlexRay network (or equipment with similar functions), thus, a FlexRay bus physical layer test platform is built. The upper computer downloads the test cases and the test commands to the test FlexRay nodes through the test FlexRay network, and obtains the test result by comparing and analyzing the communication content of the test network and the under-test network.

Description

A kind of FlexRay bus physical layer method of testing
Technical field
The present invention relates to a kind of method of the FlexRay of being used for bus physical layer test, this method is used for checking tested FlexRay node or FlexRay bus system physical layer whether to satisfy the coherence request of FlexRay bus protocol.
Background technology
FlexRay is a kind of high speed confirmability that is used for automobile; The bus system that possesses failure tolerant; FlexRay is through transmission information in the time slot of confirming; And the failure tolerant on two passages and the transmission of redundant information, satisfied new x-by-wire system design thought to the rate of information throughput especially failure tolerant and deterministic ever-increasing demand of time.Since exist subjective factor for understanding by the described FlexRay bus protocol of natural language, therefore, particularly important for the testing protocol consistency checking work of FlexRay bus physical layer.In order to check FlexRay node or FlexRay bus system physical layer whether to satisfy the coherence request of FlexRay bus protocol, need to propose a kind of FlexRay bus physical layer method of testing.
Summary of the invention
For whether the physical layer of checking FlexRay bus system or FlexRay node satisfies FlexRay bus protocol coherence request, the present invention proposes the FlexRay bus physical layer method of testing that a kind of local test method combines collaborative method of testing.Host computer and several tests FlexRay node are formed a test FlexRay network and a tested FlexRay network respectively through USB-to-FlexRay (the perhaps equipment of similar functions), make up a FlexRay bus physical layer test platform (as shown in Figure 1).Host computer draws test result through Content of Communication and tested network communication content on contrast, the judgement test network.Test command and test case arrive test node through test FlexRay network download.Wherein each test FlexRay node all has microcontroller and 2 road FlexRay communication systems, wherein one the road is connected to test FlexRay network, and another road is connected to tested FlexRay network.
Description of drawings
Accompanying drawing 1 is a kind of FlexRay bus physical layer test principle figure, wherein:
1. be host computer PC;
2. be test FlexRay network;
3. be tested FlexRay network;
4., 5. ... 6. be respectively FlexRay node 0, FlexRay node 1 ... FlexRay node n-1.
Embodiment
A kind of FlexRay bus physical layer of the present invention method of testing; Utilize host computer and several tests FlexRay node to form a test FlexRay network and a tested FlexRay network respectively, make up a FlexRay bus physical layer test platform (shown in accompanying drawing 1) through USB-to-FlexRay (the perhaps equipment of similar functions).Wherein each test FlexRay node all has microcontroller and 2 road FlexRay communication systems, wherein one the road is connected to test FlexRay network, and another road is connected to tested FlexRay network.
Wherein test network is the passage of test FlexRay node and host computer.To test FlexRay node, each is tested the correlation behavior information of FlexRay node and also returns host computer through this network through this network download for all test commands of host computer and test case.
Microcontroller is the processing center of test FlexRay node; Main processing is from the information of test network; Carry out the order of dependence test use-case; Explain that test case order and monitoring lower floor are provided with the relevant information of service and processing FlexRay controller, comprise FlexRay Frame and FlexRay controller state.Monitoring, be embodied as FlexRay physical layer to be tested operational environment and network failure service are set.
Host computer is responsible for coordinating the work of whole test platform, and through the result to the FlexRay bus node that comes the analysis of the self-test FlexRay network and the tested FlexRay network information, draw to be tested or the test of FlexRay bus system physical layer.This judge conclusion comprises 3 kinds of situation:
(1) passes through
Observed result satisfies test purpose, meets coherence request fully.
(2) failure
Observed result does not satisfy coherence request.Failure can be divided three classes: observed result does not reach test purpose; Test result satisfies test purpose but has mistake; Uncertainly whether satisfy test purpose.
(3) uncertain
Observed result satisfies coherence request, but does not determine whether to reach test purpose.

Claims (2)

1. FlexRay bus physical layer method of testing; It is characterized in that: this method combines collaborative method of testing for the local test method; Utilize host computer and several tests FlexRay node to form a test FlexRay network and a tested FlexRay network respectively, make up a FlexRay bus physical layer test platform through USB-to-FlexRay (the perhaps equipment of similar functions).Host computer draws test result through Content of Communication and tested network communication content on contrast, the judgement test network.Test command and test case arrive test node through test FlexRay network download.
2. according to the described test of claim 1 FlexRay node; It is characterized in that: each test FlexRay node all has microcontroller and 2 road FlexRay communication systems; Wherein one the road be connected to test FlexRay network, another road is connected to tested FlexRay network.
