In this paper, we propose an enhanced PI speed control algorithm to improve the engagement performance by synchronizing the engine rotation speed and the rotation speed of the drive motor at engine start in a parallel hybrid vehicle. By shortening the engine clutch engagement time as much as possible, the EV acceleration response characteristic, which is a disadvantage of the parallel hybrid vehicle, can be improved and the energy used to maintain heavy engine rotation can be minimized. The proposed algorithm has been validated through simulation using Matlab and vehicle test results on Grandeur hybrid vehicle

Recently, The skill that model can be applied to embedded software development project through model-based design workflow by using MATLAB/simulink is on the rise. In these days, there are many cases to partially generate code of the targer processor in the form of Rapid Prototype, but in this paper, we generate and compile the entire code of the target processor work through the process. Performed without hand coding of the target processor code generation and compile work and was debugging target processor for controlling the actual motor to be able to control. The design of the algorithm, depending on the type of motor can be controlled using the Rapid Prototype. Use Simulink’s, RAppID Toolbox’s library and needed user library for the target’s setting and designing algorithm. User library is created by MATLAB/Simulink’s Legacy code tool function, TLC(Target Language Compiler), S-Function(Systems-Function). When the design is done, go through the debugging process after code generation and compile task. To perform current control of IPMSM and to measure execution time and were able to get satisfactory results.

The 4WD TMED vehicles have a drive system with a rear wheel drive system added to the existing front wheel drive 2WD TMED system. The system has the NVH problem of 4WD booming and transfer rattle noise, as in the existing 4WD vehicles. The main cause of the NVH problem is engine torque fluctuations. The existing solution to this problem is to solve the problem by adding a noise reduction device or increasing the coupling torque. In this paper, we propose an electric-engine fluctuation canceling (EFC) algorithm that can solve the NVH problem by canceling the engine torque fluctuation to the drive line. HSG speed was used to generate EFC motor torque, and Band Pass Filter and RLS Adaptive Filter technology were used. The EFC torque is added to the feed-forward term to the existing motor torque command to eliminate engine torque fluctuations. The proposed EFC algorithm has been verified through actual vehicle tests, and it has been validated that it has an improved effect over or equal to the existing NVH improvement method.
