Abstract
This paper describes a developement of realtime measurement system of the road friction between a tire and road when the car is turning a corner. The priciple of the measurement system is by solving the equation between the lateral force of a tire from the centrifugal force and the lateral force from the deformation of the tire. To solve the equation, the informations of car velocity, weight acting on the tire, turning radius, slip angle, modulus of rigidity of the tire, and so on are required. In this paper, we propose the concet for the measureing system. The consideration of the lateral force is explained. The experimental setup for the measurement system is introduced, and the experimental results are shown for the feasibility of the proposed measurment system for road friction.
