| 摘要 |
The present invention relates to a method for estimating the rolling resistance of a wheelset of a moving vehicle and the effective radii of the wheels of said wheelset, said vehicle being equipped with at least two wheels (1) fitted with tyres, the method comprising: measuring or estimating the value of the angular velocity Omega at which each of the wheels (1) of the wheelset rotates, - measuring or estimating the value of the driving torque tau applied to the wheelset, characterized in that the method employs an observer of the wheel dynamics based on the theory of the slip modes, the input signals of which are the value of the angular velocity Omega of each wheel (1) of the wheelset and the value of the driving torque tau applied to the wheelset (1). |
