Problems solved by technology

[0003] 1) Testing on a real vehicle requires the cooperation of other ECU components, but if other ECU components are developed and then tested, the development progress of the Internet of Vehicles will obviously lag behind the development progress of the complete vehicle
[0004] 2) It is relatively difficult to test the rollover alarm function on a real vehicle, and there is a risk of the vehicle falling
[0005] 3) Some faults are difficult to appear during the test on the real vehicle, resulting in incomplete testing of the Internet of Vehicles system
[0006] 4) The working voltage state of the Internet of Vehicles system cannot be adjusted, or the adjustment is laborious, and it is impossible to test whether the Internet of Vehicles system can work normally under different working voltage states

no. 1 example

[0053] Such as figure 1As shown, the IoV testing system may include: a host computer 101 , a mobile terminal 102 , a background data server 103 and an IoV testing platform 104 . The Internet of Vehicles test platform 104 includes a vehicle CAN bus 10 , a vehicle ECU 20 , a vehicle T-BOX 40 and a CAN-BOX / VSPY 50 .

[0054] The vehicle-mounted ECU 20 is connected to the vehicle-mounted CAN bus 10 , and is used to execute corresponding actions according to instruction data obtained from the vehicle-mounted CAN bus 10 or according to manual operations.

[0055] In this embodiment, the vehicle-mounted ECU 20 generally includes ECU components directly related to the Internet of Vehicles system. Specifically, the vehicle-mounted ECU 20 may include, for example, one or more of a PEPS controller, a BCM controller, an instrument panel controller, and an audio head unit.

[0056] The Internet of Vehicles test platform 104 also includes a clutch switch simulation device, a brake switch ...

[0071] This embodiment is a further optimization of the first embodiment. Combine below figure 2 The Internet of Vehicles test platform 102 of this embodiment will be further described.

[0072] Such as figure 2 Shown is a schematic diagram of the Internet of Vehicles test platform of the embodiment of the present invention. The Internet of Vehicles test platform 102 can be configured as a vertical cabinet. The cabinet is embedded with a switch 201 related to the test, an indicator light 202 and a vehicle ECU 20 . The cabinet also adds components such as power fuses, circuit breakers, and cooling fans ( figure 2 not shown).

[0073] Specifically, buttons 201 for simulating a clutch switch, a brake switch, a lock switch, an unlock switch, a door status switch, and a danger alarm switch are provided on the cabinet, and the above switches can be simulated to be turned on or off by manual buttons to change the state of the vehicle. The cabinet is also provided with indica...

[0079] Such as image 3 Shown is a flow chart of a test method based on the first embodiment of the Internet of Vehicles test system, which mainly includes the following steps:

[0080] In step S310, the mobile terminal 102 sends instruction data to the vehicle CAN bus 10 via the background data server 103 and the vehicle T-BOX40, or the host computer 101 sends instruction data to the vehicle CAN bus 10 via the CAN-BOX / VSPY50 .

[0081] In this embodiment, the mobile phone mobile terminal 102 sends a remote control instruction to the background data server 103, such as: remotely open the door, remotely turn on the low beam, and remotely start the instruction, and the background data server 103 forwards the remote control instruction to the vehicle T- BOX40 is uploaded to the vehicle CAN bus 10 by the vehicle T-BOX40. Or, the instruction data sent by the host computer via CAN-BOX / VSPY50. or,

[0082] The fault data simulation unit 70 in the host computer 101 generates CAN b...

Abstract

The invention discloses an Internet of Vehicles test system and a test method thereof. The Internet of Vehicles test system comprises an upper computer, a mobile phone terminal, a background data server and an Internet of Vehicles test platform. The Internet of Vehicles test platform comprises a CAN bus; a vehicle-mounted ECU which executes corresponding actions according to the instruction data obtained from the CAN bus or manual operation; a Vehicle-mounted T- BOX which is used for uploading the state data on the CAN bus to a background data server so that the mobile phone terminal can readthe state data; a CAN-BOX / VSPY which uploads the data on the CAN bus to an upper computer, so that the upper computer monitors whether the data on the CAN bus are correct or not. The Internet of Vehicles system does not need to be tested on a real vehicle, and many problems caused by testing on the real vehicle are avoided.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a testing system and a testing method for the Internet of Vehicles. Background technique [0002] With the continuous development of the Internet of Vehicles system, the testing of the functions of the Internet of Vehicles system has also received extensive attention. Since multiple ECUs (Electronic Control Units) of the entire vehicle are involved in testing the IoV system, testing and verification is usually performed on a real vehicle at present. However, testing and verification of the Internet of Vehicles system on a real vehicle generally has the following defects: [0003] 1) Testing on a real vehicle requires the cooperation of other ECU components, but if other ECU components are developed and then tested, the development progress of the Internet of Vehicles will obviously lag behind the development progress of the complete vehicle. [0004] 2) It is r...
