초록
Recently, the information of road grade is becoming more important in the intelligent vehicle system. First, road grade can be used to compensate the unexpected load on the powertrain system. Also, road grade information is important when observing its global position accurately. In this research, the observation of pitch motion is proposed to make the road grade data accurate. First, its linear behavior with some dominant variables is analyzed by simulation using CarSim. And also, time constant with first order dynamic system is introduced to reflect its delay behavior in vehicle pitch motion.
