Abstract

Recently, Direct Yaw-moment Control (DYC) system has become a standard active safety device in automobile market. DYC system activates to stabilize vehicle motion to prevent the vehicle from falling into unstable driving situation like spin or plow by applying braking forces in order to induce additional yaw moment input. However, the relationship between driving characteristic of a human and the activation state of DYC system has not been researched. Therefore, we evaluate the effect of DYC system considering human driving behavior by using a driving simulator which is installed with DYC algorithm, reproducing emergency driving situation. From the results of the experiment of emergency obstacle avoidance for 5 objects, it is concluded that the DYC system is effective to stabilize the vehicle in the situation of emergency obstacle avoidance, and the effect of the DYC system is different depending on the characteristic of the driver.
