特徴とする車両走行状態量演算装置。 A turning radius calculating means is provided for calculating a turning radius when the vehicle is running based on the rotational speed difference between the left and right wheels or a steering angle signal, and the running state quantity of the vehicle is calculated based on the calculated value of the turning radius calculated by the turning radius calculating means. A vehicle running state quantity calculation device that calculates a vehicle speed, a vehicle speed detection means for detecting a vehicle speed, a minimum turning radius setting means for setting a minimum value of a turning radius that can actually occur based on a vehicle speed signal from the vehicle speed detection means; and if the calculated value of the turning radius calculated by the turning radius calculation means is smaller than the minimum value of the turning radius set by the minimum turning radius setting means, the calculated value of the turning radius is set as the minimum turning radius. 1. A vehicle running state quantity calculation device, comprising a replacement means for replacing the value with a minimum value set by the means.
