Problems solved by technology
In the simulation test, for example, the dynamic simulation test engineer uses the vehicle model provided in the vehicle dynamic simulation test software to test the vehicle dynamics and economy, and the vehicle handling stability simulation test engineer uses the vehicle stability However, this type of simulation test is a pure simulation test without the participation of a real vehicle controller, so the test results cannot truly reflect the performance of the vehicle
On the other hand, HIL test engineers use simple vehicle models and test benches to conduct basic functional tests of real vehicle controllers. However, this test method can simulate limited working conditions and cannot accurately test vehicles under the control of real vehicle controllers. Most of the power, economy and vehicle stability tests

The invention provides a combined type HIL test system and a control method thereof. The system comprises a plurality of simulation test platforms for testing the performance of a vehicle according to vehicle models provided by multiple corresponding simulation test software and outputting vehicle performance parameters, a communication module, an HIL test platform which interacts with the multiple simulation test platforms through the communication module so as to synchronously obtain the vehicle performance parameters from the multiple simulation test platforms and carry out HIL test on the vehicle according to the vehicle performance parameters. According to the system and the method, complex model parameters of the multiple complex simulation test software can be used to realize the multiple vehicle performance tests under a real controller, and the accuracy of a test result is high.
Description
technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a combined HIL testing system and a control method thereof. Background technique [0002] At present, the vehicle performance test is basically divided into two types: simulation test and HIL (hardware-in-the-loop, hardware-in-the-loop) simulation test. In the simulation test, for example, the dynamic simulation test engineer uses the vehicle model provided in the vehicle dynamic simulation test software to test the vehicle dynamics and economy, and the vehicle handling stability simulation test engineer uses the vehicle stability However, this type of simulation test is a pure simulation test without the participation of a real vehicle controller, so the test results cannot truly reflect the performance of the vehicle. On the other hand, HIL test engineers use simple vehicle models and test benches to conduct basic functional tests of real vehicle controllers. However, ...
