Recently, due to improvement of vehicle driving performance improvement by independent operation per vehicle wheel and fuel efficiency improvement by simplification of driving system, the study on independently operable in-wheel motor is actively in progress. The commercialization, however, is delayed due to security of durable performance and credibility of actuator, security of vehicle safety in case of drive motor malfunction, and reduced ride & handling performance due to weight increase of wheels. In this study, in order to resolve the ride & handling issue and fuel efficiency among such, electric vehicle applied with independent operation was modelled using MATLAB/Simulink, and CarSim was utilized to perform dynamic analysis of vehicle. The simulation environment thus constructed was used to execute development and verification of control algorithm for vehicle steering performance improvement in order to secure base technology for driving performance improvement of independently operated vehicle.

Nowadays researches about the Eco-friendly vehicle, hybrid electric vehicle, fuel cell vehicle and electric vehicle are under active proceeding. Since most of the new energy vehicle has a motor, the regenerative braking system can be used to improve the vehicle energy utilization efficiency. The regenerative braking system can transform the kinetic energy to the electric energy through the motor in the regenerative braking. This technology played a significant role in achieving the high energy usage. When using EMB, cooperative control with regenerative brake system is necessary and the solution how to respond to EMB’s failure has to be made clear. In this paper analyzes some classification and causes of fail of regenerative brake system for fuel-cell vehicle with EMB and researches analyzing method by adding inverter model to EV simulator for fault diagnosis. In addition this paper investigates the behavior of the vehicle based on Fault diagnosis and fail safe when EMB failure occurs in running.

The purpose of this paper is to construct a control algorithm for improving the driving efficiency of 4-wheel-drive in-wheel electric vehicles. The main parts of the vehicle were modeled and the input-output relations of signals were summarized using MATLAB/Simulink. A performance simulator for 4-wheel-drive in-wheel electric vehicles was developed based on the co-simulation environment with a commercial dynamic behavior analysis program called Carsim. Moreover, for improving the driving efficiency of vehicles, a torque distribution algorithm, which distributes the torque to the front and rear wheels, was included in the performance simulator. The effectiveness of the torque distribution algorithm was validated by the SOC simulation using the FTP-75 driving cycle.
