Problems solved by technology

That is, the widely existing hardware-in-the-loop simulation systems are all aimed at a single controller. The disadvantage of a single test is mainly that when a single controller is used for closed-loop testing, the communication function test between the real controller and the virtual controller is incomplete, and the current control The accuracy of the device test is not high, the test piece is single, and the test content such as the logic function test and fault recurrence of key electrical devices cannot be fully realized
[0003] Therefore, the existing technology has the defect of not being able to discover the potential bugs of the collection system and insufficient product performance in advance

Abstract

The invention relates to a vehicle control unit and motor controller combined test system and method, and relates to the technical field of automobiles, and the system comprises a first hardware platform, a second hardware platform and an upper computer; the first hardware platform is used for executing a preset model for simulating the working environment of the vehicle control unit and is also used for injecting a fault state into the vehicle control unit; and the second hardware platform is used for executing a preset model for simulating the working environment of the motor controller, andis also used for injecting a fault state into the motor controller and an upper computer in signal connection with the first hardware platform and the second hardware platform. The upper computer isused for controlling the two hardware platforms, the vehicle control unit and the motor controller are subjected to combined testing, various working conditions and fault conditions can be simulated,the testing precision is improved, logic function testing during cooperative work of the vehicle control unit and the motor controller is achieved, and the accuracy of functional testing of the vehicle control unit and the motor controller is effectively improved.

Description

technical field [0001] The present application relates to the field of automobile technology, in particular to a system and method for joint testing of a vehicle controller and a motor controller. Background technique [0002] At this stage, component testing is based on discrete systems. Only when the vehicle is debugged will the discrete systems be combined into a collective system and debugged on the real vehicle. That is, the widely existing hardware-in-the-loop simulation systems are all aimed at a single controller. The disadvantage of a single test is mainly that when a single controller is used for closed-loop testing, the communication function test between the real controller and the virtual controller is incomplete, and the current control The accuracy of the device test is not high, the test piece is single, and the test content such as the logic function test and fault recurrence of key electrical devices cannot be fully realized. [0003] Therefore, the prior ...
