cemorsel Posted March 6, 2015 Share Posted March 6, 2015 Hi, we have a vehicle model that will run scripts for engine torque, rpm, efficiency, etc. I calculate a torque value from car engine to geartrain and differentials, then apply the torque to the wheels, Unigine handles the physics beyond that point. I need to fetch the rolling resistance experienced by the wheel, so that I can take into consideration the negative torque feedback to the engine to use it as engine load. Is there a way I can "get" the current forces on the wheel? Cem. P.S.: I am using JointWheel by the way. Link to comment
unclebob Posted March 6, 2015 Share Posted March 6, 2015 Hi, Cem! It's possible to get linear & angular velocities from the wheel. To do so you need to get a BodyRigid from wheel node and then call getAngularVelocity / getLinearVelocity Link to comment
cemorsel Posted March 9, 2015 Author Share Posted March 9, 2015 Not velocity, I'm asking for reaction forces on wheels i.e. how much torque is exerted on the wheel by the road. Link to comment
unclebob Posted March 10, 2015 Share Posted March 10, 2015 Unfortunately, total accumulated force and torque are internal BodyRigid variables so you can't get them. Link to comment
