Hi all, I need to calculate the friction coefficient between road and the tyre of the car. I came across few answers like which solves as from the following torque equation. Engine torque = braking torque + acceleration troque + Inertial torque + drag torque + rolling resistance. For braking, Engine torque = 0. and the braking torque is assumed to be Cp * (Braking pressure).Acceleration torque is taken as (F = (Mue)* (Normal force i.e., the weight on the wheel)). The inertial component is taken as J*(omega_dot). where omega_dot is the derivative of angular velocity of the wheel. is the inertial torque component significant? can it be neglected? How can the Mue of the road at slip = 0 be calculated as the Mue varies with the slip?
