Embodiment Construction
[0056]In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.
[0057] The vehicle controller 50 in the vehicle is the core component of control decision-making of the vehicle. The vehicle controller 50 is used for torque distribution. The rationality of torque distribution determines the driving performance of the vehicle. The vehicle controller 50 needs to be fully tested before being used. The performance test of the vehicle controller 50 generally adopts a hardware-in-the-loop simulation test system. In the prior art, a hardware-in-the-loop simulation test system is used to construct a vehicle model and a road surface model through software, and ...

The invention relates to an in-the-loop simulation testing system of a vehicle control unit. The in-the-loop simulation testing system comprises a motor rack system, a driving operation platform, a simulation control system, the vehicle control unit and a motor controller. The vehicle control unit is electrically connected with the driving operation platform and used for receiving a control signal. The motor controller receives a demand torque signal and transmits a current control signal to the motor rack system. During testing, the driving operation platform receives an operation instructionand outputs the control signal. The vehicle control unit outputs the demand torque signal to realize operation of the motor rack system. According to the in-the-loop simulation testing system of thevehicle control unit, hardware and software are combined, and the in-the-loop simulation testing system is closer to the operation state of a complete vehicle, and improves the testing accuracy of thevehicle control unit.
Description
technical field [0001] The present application relates to the technical field of automobiles, in particular to a vehicle controller-in-the-loop simulation test system and a control method thereof. Background technique [0002] Now the simulation technology is widely used in the design and development of electric vehicles, especially the vehicle power system. The introduction of simulation technology into the development of automobile power system has accelerated the speed of automobile design and development. According to the different participating simulation models, it can be divided into physical simulation, mathematical simulation and hardware-in-the-loop simulation. [0003] The vehicle controller in the automobile is the core component of the control decision-making of the vehicle. The vehicle controller is used for torque distribution. The rationality of torque distribution determines the driving performance of the vehicle. The vehicle controller needs to be fully...
