1. A method for monitoring vehicle handling of a vehicle with respect to vehicle stability using a measured variable reflecting a yaw rate or lateral acceleration of the vehicle and a steering angle value, the method comprising the acts of: normalizing gradients of regression lines of the measured variable and the steering angle value to the same units; comparing normalized gradients of the regression lines of the measured variable to normalized gradients of the regression lines of the steering angle continuously over a plurality of analysis time windows; and upon detecting a significant deviation between the gradients, concluding an unstable driving condition of the vehicle.
