Crosswind is one of the major factors that affects on driving stability. Therefore, in order to make up for it, the performance evaluation for MDPS which assist to ensure vehicle driving stability is very important. But the driving stability evaluation of vehicle system for crosswind is difficult to take a vehicle test due to environment restriction. In this paper, we want to develop the method and criteria of evaluating driving stability for crosswind of MDPS with HiLS quantitatively. The purpose of this study is to help the vehicle development by reviewing and applying for the method which can evaluate driving stability for crosswind under various condition in virtual driving environment based on MDPS HiLS.

In this study, The control Logic is developed for assisting driver"s maneuver at urgent steering to avoid an obstacle at front. The start point of control is decided by driver"s intention. For appropriate steering assist torque to avoid the sudden obstacle target yaw rate is created through lane recognition of Camera Sensor and the relative distance from forward vehicle with Radar Sensor. Yaw moment is created to follow the target yaw rate as mentioned through steering torque of MDPS and differential braking with ESC module. Lastly, actual vehicle test is performed to verify it.

This paper propose improved longitudinal safety system on near cut-in situation by vehicle to vehicle communication. Some longitudinal active safety systems used Radar sensor and Camera sensor such as AEB(Autonomous Emergency Braking) system and ACC(Adaptive Cruise Control) system have blind spot zones because of sensor"s Field of View. When a target vehicle in lane near the subject vehicle try to cut in rapidly in this area, Sensors can"t recognize that and Safety systems don"t work normally. Therefore To prevent this situation, this paper design the longitudinal safety system based on V2V communication. and the performance evaluation was conducted to verify this system through Software-In-the-Loop-Simulation.

As a part of the X-by-wire technology, brake-by-wire system replaces hydraulic brake system with electrical components. The EMB system is typical shape of BbW. So, in this research a hardware-in-the-loop simulation of the EMB is developed in order to test and assess the EMB system. For using to compare with EMB HiLS system, CBS HiLS system is also developed. Finally, the performance evaluation was conducted to compare both systems by using the constructed EMB/CBS HiLS system.
