Embodiment 1

[0062] One of the test methods and test equipment implementations applicable to the vehicle navigation multimedia terminal of the present invention, such as figure 1 as shown,

[0063] It includes a computer test terminal 1, a data transponder 2 and a vehicle navigation multimedia terminal 3 under test.

[0064] Wherein, the computer test terminal 1 is the initiator of the whole test, responsible for generating the test data required by the test personnel, starting the test and sending the test data to the data transponder 2, receiving and processing the data sent from the vehicle navigation multimedia terminal 3 under test Feedback. The module structure of the computer test terminal 1 of the present embodiment is shown in figure 2 : The test items that have have real vehicle simulation test 101 and non-real vehicle simulation test 102 two big categories, no matter what kind of test project, present embodiment all provides manual test 104 and automatic test 105 two kinds o...

Embodiment 2

[0087] One of the implementations of a test method and test equipment applicable to a vehicle navigation multimedia terminal of the present invention, this embodiment is based on embodiment 1, and further clarifies the functional modules of the computer test terminal 1 . Such as figure 2 As shown, the test items of the real vehicle simulation test 101 of the computer test terminal 1 include ACC switch simulation 107, steering wheel control simulation 109, radar information simulation 108, air conditioning operation simulation 110, and vehicle status information simulation 111; The test items include touch screen operation 112 and panel button operation 113 . There are two test methods of manual test 104 and automatic test 105 when testing the above test items. If the automatic test 105 mode is selected, the pre-test path file 106 must be made at first. During the production process, testers can choose various simulation test operations provided by the test system, and set t...

Embodiment 3

[0092] One of the implementation modes of a test method and test equipment applicable to a vehicle navigation multimedia terminal of the present invention, this embodiment is based on the embodiment 1, and further clarifies the implementation structure of the data transponder 2 . Such as figure 1 As shown, the computer test terminal 1 is connected to the data transponder 2 using a USB port, and the data transponder 2 is connected to the tested vehicle navigation multimedia terminal 3 in the form of can-bus and GPIO ports, so as to transmit data that requires real vehicle simulation. For the test item data, the data transponder 2 is connected with the vehicle navigation multimedia terminal 3 under test in the form of uart serial port, so as to transmit the test item data not simulated by the real vehicle. The main task of the transponder 2 is to realize data distribution and correct transmission.

[0093] image 3 is the implementation diagram of the data transponder 2. The...

Abstract

A test method and test equipment suitable for a vehicle navigation multimedia terminal, comprising: a computer test terminal, a data transponder and a vehicle navigation multimedia terminal to be tested. The computer test terminal distributes the test item data and parameters through the data transponder, sends the test item data and test instructions to the vehicle navigation multimedia terminal, and the obtained test response information is fed back to the computer test terminal through the data transponder. The test equipment and method can not only test the vehicle navigation multimedia terminal connected to the real vehicle, but also carry out the real vehicle simulation test on the vehicle navigation multimedia terminal disconnected from the real vehicle; both manual testing and automatic testing can be performed. The test equipment and method also have the function of sending test feedback information to the Internet vehicle comprehensive service platform. The invention provides a convenient multi-port connection mode, in which data transmission follows a specific communication protocol. The invention has a simple and practical structure, and is suitable for vehicle navigation multimedia terminals used in various vehicle types.

Description

technical field [0001] The invention relates to the technical field of vehicle equipment testing, in particular to a testing method and testing equipment suitable for vehicle navigation multimedia terminals. Background technique [0002] With the rapid development of the automobile industry, a car navigation multimedia terminal integrating driving navigation, radio, USB / SD / DVD video player, Bluetooth call, digital TV and other functions has gradually become the standard configuration of the car. [0003] In the prior art, the vehicle navigation multimedia terminal must undergo strict testing before leaving the factory, and the traditional method is manual testing. However, manual testing is time-consuming and laborious, and the process is cumbersome and inefficient. [0004] China's invention patent application (patent application number: 201210484382.0) discloses a "vehicle diagnostic equipment and method based on automotive multimedia terminals". , but not for testing an...
