Example two
Fig. 7 is a schematic flowchart of a method for testing an onboard remote communication box according to a second embodiment of the present application, where the method of the present embodiment may be executed by the onboard remote communication box testing system according to the first embodiment.
As shown in fig. 7, the method for testing the vehicle-mounted remote communication box of the embodiment includes:
s101, the upper computer sends a test instruction to the TBOX to be tested.
In this embodiment, the upper computer sends a test instruction to the TBOX to be tested by executing the test script, and the test instruction may be a query instruction or a control instruction as needed. The query instruction is used for querying relevant information of the vehicle, such as position information, attitude information, state information and the like, and the control instruction is used for controlling equipment or components on the vehicle, such as a vehicle door, a vehicle lamp, an air conditioner and the like.
Optionally, in this embodiment, as shown in fig. 3 or fig. 4, the upper computer may send the test instruction to the TBOX to be tested through the TSP platform, that is, the upper computer sends the test instruction to the TSP platform first, and then the TSP platform forwards the test instruction to the TBOX to be tested.
It can be understood that when functions of the to-be-tested TBOX under various scenes need to be tested, the functions can be implemented by sending a plurality of test instructions to the to-be-tested TBOX, such as a vehicle door closing instruction, an air conditioner opening instruction, a position information query instruction, an oil quantity query instruction, and the like.
S102, the TBOX to be tested generates a first CAN message comprising a test instruction, and the first CAN message is sent to a CAN communication box through a CAN bus, so that the CAN communication box forwards the first CAN message to a CANoe tool.
In this embodiment, for convenience of distinguishing and describing, the CAN message generated by the TBOX to be detected is called a first CAN message.
In the step, in order to meet the communication requirement of the CAN network, when the TBOX to be tested receives the test instruction, according to the test instruction and the generation rule of the CAN message, a CAN message including the test instruction, namely a first CAN message is generated and sent to the CAN bus, and meanwhile, the CAN communication box collects the first CAN message from the CAN bus and transmits the collected first CAN message to the CANoe tool in the upper computer through the data line.
S103, the CANoe tool processes the first CAN message to generate a second CAN message, and the second CAN message is sent to the CAN communication box, so that the CAN communication box forwards the second CAN message to the TBOX to be detected.
In this embodiment, for convenience of distinction and description, the CAN packet generated by the CANoe tool is called a second CAN packet.
In the step, after receiving the first CAN message, the CANoe tool analyzes the first CAN message to obtain a test instruction, then executes the TBOX test engineering to simulate the vehicle to execute the test instruction to obtain response data corresponding to the test instruction, and finally generates a second CAN message including the response data according to the generation rule of the CAN message.
It will be appreciated that the response data may vary from test instruction to test instruction. Exemplarily, if the test command is a position information query command, the response data is the current position information of the vehicle; and if the test command is a vehicle door closing command, the response data is the state of the vehicle door after the closing command is executed.

And S105, the upper computer checks the response data according to the target test case to generate a test result.
In this step, after receiving the response data, the upper computer verifies the response data by using a test case corresponding to the test instruction, i.e., a target test case, according to the test script to generate a test result.
It can be understood that the test instructions are different, and the test cases are also different, for example, the car door closing instruction corresponds to different test cases with the position information query instruction. And if the test instruction sent in the test is the vehicle door closing instruction, the test case corresponding to the vehicle door closing instruction is the target test case for verifying the response data.
The test cases corresponding to different test instructions are also written and stored on the upper computer, and each test case comprises expected response data corresponding to different test instructions. If the expected response data corresponding to the door closing command is as follows: the door is closed.
In a possible implementation manner, in this step, the upper computer judges whether the received response data is consistent with the expected response data in the target test case or not by executing the test script, and generates a corresponding test result, specifically, if the response data is consistent with the expected response data, a first test result is generated, and the first test result is used for indicating that the test is passed; and if the response data is inconsistent with the expected response data, generating a second test result, wherein the second test result is used for indicating that the test does not pass.
Optionally, before S101, the method of this embodiment further includes:
and the upper computer sends a power-on control instruction to the program-controlled power supply so that the program-controlled power supply supplies power to the TBOX to be detected. As can be seen from fig. 5, the upper computer can send a power-on control instruction to the program-controlled power supply by executing the power supply switching script, so that the program-controlled power supply operates in a power supply state, thereby ensuring normal operation of the to-be-tested TBOX.
In this embodiment, a test instruction is sent to a to-be-tested TBOX by an upper computer, the to-be-tested TBOX generates a first CAN message including the test instruction, and the first CAN message is sent to a CAN communication box through a CAN bus, so that the CAN communication box forwards the first CAN message to a CANoe tool, the CANoe tool processes the first CAN message to generate a second CAN message, and sends the second CAN message to the CAN communication box, so that the CAN communication box forwards the second CAN message to the to-be-tested TBOX, and the second CAN message includes response data of the test instruction; analyzing the second CAN message by the TBOX to be detected to obtain response data, and feeding back the response data to the upper computer; and the upper computer checks the response data according to the target test case to generate a test result, wherein the target test case is a test case corresponding to the test instruction. Under the condition of not depending on actual vehicles and manual intervention, the automatic test of the TBOX is realized, and the test efficiency and accuracy of the TBOX are improved.
