Abstract:
A method for determining an unstable driving condition of a motor vehicle, comprising the steps of:during a cornering of the vehicle, measuring at least one of (a) a lateral acceleration and (b) a yaw rate of the vehicle using a measuring device, and measuring a road speed of the vehicle using a speedometer; measuring a steering angle of the vehicle; computing, as a function of the steering angle and the road speed, a value of at least one of (a) the lateral acceleration and (b) the yaw rate; and determining at least one of (a) a first difference between the measured lateral acceleration and the computed lateral acceleration and (b) a second difference between the measured yaw rate and the computed yaw rate, and further comprising the step of generating a rating factor as a function of at least one of the first and second differences, and wherein the rating factor is weighted for the range 0 to 1.
