Abstract:
A method for computing a vehicle body slip angle in a vehicle movement control, comprising the steps of:computing a tire slip angle .alpha. from a yaw rate .gamma., a vehicle speed V, a vehicle body slip angle .beta. which is given as an initial value or a preceding computed value and a road wheel steering angle .delta.;computing a cornering force Y from a dynamic model of the tire by taking into account at least the tire slip angle .alpha.; andcomputing a hypothetical vehicle body slip angle .beta..sub.e from the cornering force Y, the vehicle speed V and the yaw rate .gamma.;wherein the tire slip angle .alpha. is computed by feeding back only the hypothetical vehicle body slip angle .beta..sub.e while the yaw rate .gamma. and the vehicle speed V are based on measured values.
