    Force on wheels in an accelerating vehicle

    Assume that a motorcycle of mass m has two wheels that are equidistant from its centre i.e the force on each wheel is m*g/2. If the motorcycle accelerates forward, will the two forces on each wheel (measured instantaneously) remain the same? If not, how can one mathematically describe the...

    Estimating Wheel Torque From Engine Torque

    Very helpful, thanks. If I can't obtain vehicle speed from CAN, I assume that I could get a decent estimate from GPS?

    Estimating Wheel Torque From Engine Torque

    It seems possible to obtain engine torque and RPM from a truck CAN bus. I'd like to estimate tractive force at the wheels given these two values. How should I go about computing torque at the wheels? Wouldn't I need gear ratio, which doesn't seem obtainable from the CAN bus? Do I need to...
