Method and device for calculating turning radius of vehicle taking load movement thereof into consideration

摘要

A method of and a device for determining a turning radius of a vehicle, accurately, without being influenced by the load movement of the vehicle, are disclosed. The rotational angular velocities of left and right tires are detected, respectively. The turning radius of the vehicle is determined, based on the detected rotational angular velocity, by taking a change in effective rolling radiuses due to the load movement of the vehicle into consideration.
