Yaw Rate Sensor
When the vehicle turns left or right, the yaw rate sensor outputs a voltage. However, the sensor outputs an offset voltage when the vehicle is stopped. The audio-navigation unit calculates the relative bearing of the vehicle from the offset voltage. Since the vehicle may generate the yaw rate even when it is stopped (when the vehicle is spun on a turn table), the audio-navigation unit inhibits the incorrect calculation using the yaw rate sensor temperature information.
