Abstract

In order to provide a natural feeling in turn for general drivers in daily driving, a method was examined for adjusting the pitching behavior produced by steering in control of acceleration and deceleration linked with lateral motion. In consideration of the characteristic that the pitch angle response is twice the steering frequency, a control law was devised to reduce unnatural feeling in turn. The effect of the control law and the controlled variable was verified by simulation, and it was confirmed that the timing at which the pitching behavior occurs can be adjusted without impacting the rolling behavior. Next, actual vehicle tests were conducted, and the vehicle behavior was confirmed to be similar to that in the simulation. In addition, sensory evaluation showed that the method is effective in enhancing the feeling in turn, and that there is an appropriate value for the control strength.
