Frictional coefficient estimating method for e.g. passenger car, involves estimating frictional coefficient within linear range of tire using single track model, and measuring speed of vehicle from wheel angle and greed rate

摘要

The method involves estimating frictional coefficient between road and a tire of a motor vehicle within a linear range of the tire using a single track model, and measuring characteristic speed of a vehicle from a wheel angle and a greed rate. The characteristic speed is derived from a transfer factor of a transfer function of the wheel angle to the greed rate. The frictional coefficient is estimated based on the nominal characteristic speed. An independent claim is also included for a control device for a motor vehicle.
