    摘要： A vehicle (10) includes a control system (18) that is used to control a vehicle system. The control system determines an axle torque, and longitudinal forces at each tire in response to the axle torque. Lateral forces at each tire are determined in response to the longitudinal forces. The control system of the vehicle is determined in response to the longitudinal and lateral forces.

    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.
