Abstract:
1. A method of measuring a tilt angle of a traveling road, the method comprising: detecting, by a vehicle speed sensor, a vehicle speed; detecting, by a longitudinal acceleration sensor, a longitudinal acceleration of a vehicle; detecting, by a yaw rate sensor, a yaw rate of the vehicle; receiving, by a controller, an input of a signal of the vehicle speed sensor, the longitudinal acceleration sensor, and the yaw rate sensor; calculating, by the controller, a traveling acceleration based on the detected vehicle speed; calculating, by the controller, a first tilt angle of the traveling road based on the traveling acceleration and the longitudinal acceleration; determining, by the controller, when a value of the detected yaw rate is equal to or greater than a predetermined value; and calculating, by the controller, a second tilt angle to apply a compensation value set to the first tilt angle in response to detecting the yaw rate equal to or greater than a predetermined value to measure the tilt second angle while the vehicle is turning.
