HI, I am facing a problem using newton vehicle. I have real parameters for heavy truck. When I applied the same torque as given by the manufacturer, maximum speeds are no where near the expected. At the same time my vehicle climbs up any gradient, if I set the mass to a lower value. Main problem, I observed here is with the rolling resistance, I mean, the vehicle comes to a constant speed at a particular torque, but this torque is increasing from gear to gear(with the vehicle speed). The variation so much, which is not expected. How can I avoid this? Friction values are not effecting my speed. very low friction values reduce the speed too much. but beyond certain value, its not effecting at all. Any Idea????
