    摘要: In a method for operating a vehicle with wheel suspensions which each have a characteristic curve, the characteristic curve generates a relation between the weight of the vehicle, applied to each wheel suspension, and the respective height of the vehicle at the wheel suspension point. At least two height sensors detect the height at the wheel suspensions, a reference height is associated with the height sensors and represents a pre-defined loading state of the vehicle. The method provides: detecting the height, determining the forces applied to the vehicle, determining the acceleration of the vehicle on the basis of the forces applied to the vehicle, determining an estimated value for the mass of the vehicle from the forces and the acceleration of the vehicle, and determining values representing the reference heights from at least the estimated value for the mass of the vehicle, the characteristic curves of the wheel suspensions, and the detected heights.

    摘要: 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.
