Abstract
A washer-type strain sensor, which generates an output representing a load acting thereon, is arranged between the vehicle body and the wheel. A dynamic load acting on the wheel is measured on the basis of the outputs of the strain sensor when the vehicle is traveling. A lateral force, a lateral-force coefficient, a slip angle, and steering characteristics of the wheel are obtained on the basis of the measured dynamic load, and thereby the cornering characteristics of the wheel are obtained.
Claims9
A method for measuring dynamic characteristics of a wheel of a vehicle, the vehicle having a vehicle body, the method comprising:
- providing a washer shaped strain sensor having an inner bore, the strain sensor generating an output representing a load acting on the strain sensor;
- arranging the strain sensor between the vehicle body and the wheel;
- measuring the dynamic load acting on the wheel based on the outputs of the strain sensor when the vehicle is traveling;
- and
- obtaining dynamic characteristics of the wheel based on the measured dynamic load,
- wherein cornering characteristics of the wheel are obtained based on the measured dynamic load, the vehicle having front and rear wheel and front and rear axles,
- wherein slip angles of the front and rear wheels are respectively obtained, and wherein steering characteristics of the wheel are obtained based on the slip angles of the front and rear wheels.
