Abstract


  • The tire-road friction coefficient is critical to

    vehicle longitudinal, lateral and roll dynamics and control

    because tire is the only contact part between the vehicle body

    and the road. However, direct measurement of tire-road

    friction coefficient is impossible in practice. This paper

    presents a novel cost effective method for vehicle tire-road

    friction coefficient estimation. This method only needs the

    measurements of the wheel angular velocity, the traction/brake

    torque and the longitudinal acceleration, which are all

    available from the commonly installed sensors in ordinary

    passenger vehicles, and can be used to estimate the individual

    tire-road friction coefficient. There are three steps in the

    proposed method. Firstly, the longitudinal slip ratio is

    estimated by using a nonlinear filter with the measured wheel

    angular velocity. Then the tire longitudinal force is estimated

    by using a Kalman filter with the measured traction/brake

    torque and longitudinal acceleration. At last, the friction

    coefficient is estimated by using the recursive least squares

    (RLS) method and the results obtained from the first two steps.

    Numerical simulations are provided to validate the

    effectiveness of the proposed method. It is shown by the

    simulation results that the proposed method is effective in

    estimating the tire-road friction coefficient.
