20080201038 | Determination of the Actual Yaw Angle and the Actual Slip Angle of a Land Vehicle - In a method for determining the actual yaw rate and slip angle of a vehicle, a slip angle characteristic is first determined by a driving condition sensor system, a yaw rate sensor and a position determination system. If the slip angle characteristic remains below a threshold value, the actual yaw angle is adjusted to match the actual speed vector angle. Otherwise, the actual yaw angle is determined by a continuous value integration using yaw rate sensor values and the slip angle is calculated as the difference between the yaw angle and the speed vector angle. The slip angle is reliably determined with sufficient accuracy, without the need for additional sensors, if the values of the slip angle increase over several seconds. in addition, the yaw angle is reliably determined over long periods of time and the deviations in the values that occur in the integrating methods are adjusted at frequent intervals. | 08-21-2008 |
