Problems solved by technology
Since this static platform uses corresponding signals to replace the input and output of the driving part, the test data is limited and it is impossible to test the relevant signals of the driving part.
In addition, because there is no driving part, it is impossible to simulate the user's driving conditions, and the data obtained in this way may not be true and credible

Embodiment Construction
[0026] The present invention first discloses a vehicle dynamic diagnosis test platform, referring to figure 1 as shown, figure 1 A schematic structural diagram of the vehicle dynamic diagnosis test platform is revealed. The vehicle dynamic diagnosis test platform 100 includes a real vehicle platform 102 and a three-way device 104 . The real vehicle platform 102 has driving capability and has real vehicle components. That is, the real vehicle platform 102 has the basic functions of a commercially available vehicle, and can be regarded as a test platform based on an actual vehicle. The real vehicle components of the real vehicle platform 102 include a controller 121 and an execution unit 122 . It should be noted that the controller 121 and the execution unit 122 already exist in the actual vehicle, and in a commercially available vehicle, the controller 121 and the execution unit 122 are connected to each other according to a prescribed correspondence to realize various funct...

The invention discloses a finished automobile dynamic diagnosis and test platform which comprises a real automobile platform and a three-way device, wherein the real automobile platform has driving capability and provided with real automobile parts including a controller and an execution member. The controller is connected with the execution member through the three-way device, the controller is connected with the three-way device through pins and leads, and the execution member is connected with the three-way device through pins and leads. During dynamic driving or static status of the real automobile platform, disconnection, short out and other statues of the corresponding pins of the controller and the execution device are achieved by means of plugging of the pins of the three-way device and signal interference to simulate failures. The invention further discloses a finished automobile dynamic diagnosis and test method.
Description
technical field [0001] The invention relates to vehicle diagnosis and testing technology, more specifically, relates to a vehicle dynamic diagnosis test platform and a test method. Background technique [0002] The most important problem faced in the after-sales service of vehicles is: how to achieve a quick response to the faults complained by the aftermarket, that is, how to quickly find out the cause of the faults that caused the complaints and make improvements. In order to find the cause of the complaining faults, it is necessary to simulate these complaining faults and find the problem during the simulation. Also, care must be taken during the simulation to not cause damage to the vehicle. [0003] In the process of simulating and reproducing these complained failures. It is necessary to conduct electrical on-off and load experiments on a certain pin of the vehicle's on-board controller or on-board sensor, so the pin needs to be picked out with a pick. For the actua...
