    摘要: A system, method and computer program product is provided for detecting if a vehicle has spun. A normal force and a lateral force of each of a front and rear axle of a vehicle is estimated. A coefficient of friction representative of a surface is estimated. Lateral momenta of the front and rear axles based on the coefficient of friction and the normal and lateral forces is calculated. Whether a surplus momentum is present, is determined. If the surplus momentum is present, a yaw rate of the vehicle is integrated respect to time to obtain a vehicle rotation estimation.

    摘要: A vehicle-behavior detecting apparatus including a first-yaw-moment calculating unit, a second-yaw-moment calculating unit, and an indication-value calculating unit. Based on a linear bicycle model, the first-yaw-moment calculating unit calculates a first-yaw-moment during constant-speed turning. The second-yaw-moment calculating unit reads the longitudinal acceleration detected by an acceleration sensor in addition to the parameters read in the first-yaw-moment calculating unit, and calculates a second yaw moment during acceleration or deceleration. The indication-value calculating unit calculates a variation value in the yaw moment showing the vehicle behavior from the difference between the first yaw moment during constant-speed turning and the second yaw moment during accelerated or decelerated turning. The variation in the yaw moment due to the vehicle-load shift during accelerated or decelerated turning is compensated for by the variation value.

    摘要: A control system (24) for controlling a safety system (40) of an automotive vehicle includes a plurality of wheel speed sensors (30) generating a plurality of wheel velocity signals, a steering angle sensor (39) generating a steering actuator angle signal, a yaw rate sensor (28) generating a yaw rate signal, a longitudinal acceleration sensor (32) generating a longitudinal acceleration signal and a pitch angle generator generating a pitch angle signal and a controller (26). The controller (26) generates a longitudinal vehicle velocity in response to the plurality of wheel speed signals, the steering angle signal, the yaw rate signal, the lateral acceleration signal and the pitch rate signal. The controller (26) may determine a slip-related longitudinal velocity and a non-slip longitudinal velocity as intermediate steps.
