    摘要: A method and system (18) for determining a side slip angle for an automotive vehicle (10) includes various sensors such as a yaw rate sensor (28), a speed sensor (20), a lateral acceleration sensor (32), a roll rate sensor (34), a steering angle sensor (35), and a longitudinal acceleration sensor (36). Each of the sensors are coupled to a controller (26) that determines a side slip angle velocity in response to the sensor signals. The side slip angle velocity is compensated for due to gravity and vehicle attitude changes. Also, the side slip angle velocity is compensated for due to the non-linearity of the side slip angle. The side slip angle velocity is integrated, preferably with an anti-drift integration filter (to determine an integrated side slip angle). A steady state side slip angle is also determined based on the sensors such as the yaw rate sensor and the lateral acceleration sensor. The steady state side slip angle is filtered using a steady state recovery filter (74). The integrated side slip angle and the steady state side slip angle are combined to form a side slip angle estimate.

Positioned within the housing (52) are a roll angular rate sensor (31), a yaw angular rate sensor (30), a pitch angular rate sensor (32), a lateral acceleration sensor (27), a longitudinal acceleration sensor (28), and a vertical acceleration sensor (29). The vehicle (10) also has a safety system (38). The controller (26) determines a roll misalignment angle, a pitch misalignment angle and a yaw misalignment angle as a function of the sensor outputs of the roll rate, the pitch rate, the yaw rate, the lateral acceleration, the longitudinal acceleration and the vertical acceleration. The motion variables the vehicle along the vehicle body-fixed frames, including the roll rate, the pitch rate, the yaw rate, the lateral acceleration, the longitudinal acceleration and the vertical acceleration, are then compensated based on the detected sensor misalignments and the sensor outputs of the roll rate, the pitch rate, the yaw rate, the lateral acceleration, the longitudinal acceleration and the vertical acceleration.
