Description

technical field [0001] The present application relates to automobile testing technology, and in particular, to a testing system, a vehicle simulation device, a testing device and a testing method. Background technique [0002] With the rapid development of automotive technology, the requirements for the on-board electronic control unit (ECU) are getting higher and higher. Before being applied to the vehicle, there can be a test system to verify the function of a single ECU and the functional logic interaction between multiple ECUs. [0003] At present, the test system includes the LabCar test system. The LabCar test system can be understood as a hardware-in-the-loop system including several ECUs, and has simulated vehicle sensors and actuators (or actuators). To detect the response of the vehicle's electrical and electronic system in a normal working environment, the LabCar test system can also artificially inject faults to detect the response of the vehicle's electrical an...

AI Technical Summary

Problems solved by technology

However, in the face of the integration verification test stage, this low-integration LabCar test system is relatively isolated and thin, and there are few test services that can be covered, which cannot meet the needs of large-scale test verification in the integration verification stage.

[0006] For example, when the LabCar test system changes the ECU interface or switches between different projects, the software and hardware of the test device are greatly changed, the system flexibility is very low, it cannot be quickly adapted, and the repetitive workload is large, resulting in a development cycle. Longer, wasting test resources

Moreover, relying on the ECU's own logic function to realize data interaction, it is easy to cause the function failure of the vehicle simulation device caused by the failure of a single ECU

[0007] On the other hand, when multiple LabCar test systems are in parallel, each single vehicle test system is relatively isolated and cannot interact with data and logic functions, and lacks overall unified scheduling, which severely limits the coverage of business end-to-end tests , leading to low efficiency of test verification execution and waste of manpower and material resources

[0008] Therefore, the applicant believes that the existing LabCar testing system cannot meet the needs of large-scale testing traffic
