Claim 0:
1. A system for evaluating performance of a vehicle device having a friction component, the system comprising:
a rotation speed determination unit configured to determine a rotation speed of the friction component of the vehicle device;
a hydraulic pressure determination unit configured to determine a hydraulic pressure acting on the friction component;
a temperature determination unit configured to determine a temperature of the friction component;
a friction coefficient modeling unit configured to predict and output a friction coefficient on a basis of three or more input values, including the rotation speed determined by the rotation speed determination unit, the hydraulic pressure determined by the hydraulic pressure determination unit, and the temperature of the friction component determined by the temperature determination unit; and
a torque determination unit configured to determine an operating torque of the friction component using the friction coefficient output from the friction coefficient modeling unit,
wherein the friction coefficient modeling unit is configured to construct and output a map of friction coefficients determined on a basis of input values including a variation in the rotation speed of the friction component, a variation in the hydraulic pressure acting on the friction component, and a variation in the temperature of the friction component.
