Abstract:
A device for producing first, second, third and fourth electrical signals indicating vehicle speed, yaw rate, lateral acceleration and roll rate of a vehicle body of a vehicle, respectively, comprising:means for detecting a vehicle speed, so as to produce the first electrical signal;means mounted on the vehicle body as positioned substantially at a center of gravity of the vehicle body for detecting a turn rate of itself around a vertical axis thereof, so as to produce the second electrical signal;means mounted on the vehicle body as vertically shifted from the turn rate detection means for detecting an acceleration applied thereto in a horizontal direction transverse to a longitudinal axis of the vehicle body;means for calculating a product of the vehicle speed detected by the vehicle speed detection means and the turn rate detected by the turn rate detection means, so as to produce the third electrical signal; andmeans for calculating a quotient of a difference between the transverse acceleration detected by the transverse acceleration detection means and the above-mentioned product divided by a vertical shift distance of the transverse acceleration detection means relative to the turn rate detection means and integrating the quotient on a time basis, so as to produce the fourth electrical signal.
