Background

The common verification process of the current new energy power assembly system relates to three layers: one is an actuator level, and the key point is that the structure and the performance of hardware design meet the design requirements; one is a controller level, and the key points are function and signal level verification; the other layer is the verification of the power assembly system layer, which mainly aims at verifying that the function and the performance of the assembly system meet the design requirements. Generally, a three-electrical system of a new energy power system carries out function test and performance verification of an independent motor driving system, function test and performance verification of a battery energy storage system and function test and performance verification of a finished automobile control system.

After the motor parameter and the battery parameter are verified to meet the requirements through the power system verification device, whether the motor parameter and the battery parameter meet the performance requirements of the whole vehicle is verified through the whole vehicle joint debugging device, the difference between a whole vehicle performance simulation result and a real vehicle test value is reduced, the performance of a power system of the electric vehicle is improved, and safe and reliable operation of the whole vehicle is guaranteed.

According to the technical scheme, after assembly parameter simulation is adopted, a theoretical value of a system performance parameter is obtained; the performance of the power system is verified through the material object rack, the condition of the parameter and the actual condition is verified, but the technical scheme has the following defects.

Disadvantage 1: after a sample piece is trial-manufactured, the motor actuator or the battery module cannot be adjusted for the second time, the current common means needs to be trial-manufactured again and then verified by a dynamometer bench, and the cost is consumed due to the redesign and adjustment;

and (2) disadvantage: developing a motor actuator or a battery module in the early stage, synchronously developing and verifying the motor actuator or the battery module with a control power driving module, verifying a common control power driving module, independently verifying the common control power driving module by adopting a power level test rack, and performing certain iterative design and multiple adjustment and correction on the matching of the common control power driving module and the motor actuator or the battery module;

disadvantage 3: at present, after a motor system and a battery energy storage system are developed, the function and performance verification of a power assembly system level can be carried out, and the processes of reasonable parameter matching verification and iterative repeated design exist. The development period is long and the development cost is low.

The HiL (Hardware-in-the-Loop) Hardware-in-Loop simulation test system simulates the running state of a controlled object by running a simulation model through a real-time processor, and is connected with an ECU (electronic control unit) to be tested through an I/O interface to carry out comprehensive and systematic test on the ECU to be tested. In consideration of safety, feasibility and reasonable cost, the HiL hardware loop simulation test becomes a very important loop in the ECU development process, the number of real vehicle road tests is reduced, the development time is shortened, the cost is reduced, the software quality of the ECU is improved, and the risk of an automobile factory is reduced.
