How can I see/export the load of the Vehicle Body in Simscape Driveline which is attached to a drivetrain? For example, I have a engine which transfers 400Nm of torque trough a gearbox and a differential to the Vehicle Body. When I measure the torque via the torque sensor, it will just display the torque from the engine (considering the ratios). But how can I see the load from the Vehicle Body, which depends on the vehicle mass, vehicle speed etc.? The difference between those values should control the speed of the vehicle. Thanks!
