The climbing and road bank angle are the one of the most important information for active safety systems. But unfortunately, it isn’t easy to simply calculate since the angle is estimated from 2axis accelerometer which is also including driving acceleration and lateral slip angle. So current estimation algorithm requires complex equations and many variables from other sensors in order to extract the angles from measured acceleration. In this paper, a new angle estimation method based on 3axis accelerometer has been introduced with relatively simple equations. The performance of new approach has been evaluated by measuring the calculated angles.
