Abstract
A method of ensuring stability and good quality of yaw torque control even in the case of road surface transversal inclination and/or a rolling motion of the vehicle requires a transversal inclination identification. This is done by calculating the transversal inclination angle .alpha..sub.q, When a transversal inclination is identified, the calculating device of the vehicle can be set to counteract the transversal inclination vigorously. Calculation of the transversal inclination angle .alpha..sub.q is based on a coordinate transformation. The value a.sub.qm measured by the transverse accelerometer fixed to the vehicle is related to a value a.sub.q of the ground-related transverse acceleration calculated from other sensor signals pursuant the equation EQU a.sub.qm =a.sub.q cos .alpha..sub.q -g sin .alpha..sub.q. The solution of this equation provides the transversal inclination angle .alpha..sub.q.
