Rotational Angle SensorRotational Angle Sensor

The navigation system's rotational angle sensor senses the vehicle's changes in direction to the left or right. This information combined with the signals from the wheel speed sensors indicating the distance travelled allows the navigation control unit to calculate the route being taken and the curve radius. This data is used for the purpose of dead reckoning navigation. Not only does dead reckoning navigation boost the accuracy of vehicle positioning, it also enables route calculation to be carried out in situations where the vehicle is unable to receive GPS signals, for example when driving through a tunnel.
