How to obtain vehicle engine rotation speed or current gear in isaac sim

Omniverse Isaac Sim
1

Hello everyone, I am researching vehicle dynamics in isaac sim and I am very grateful to nvidia for providing the physX Vehicle toolkit.
But I encountered a lot of data that I couldn’t obtain during use, such as engine rotation speed, current gear of the vehicle, and so on.
But these are GitHub - NVIDIA-Omniverse/PhysX: NVIDIA PhysX SDK It’s all inside.

But I didn’t find these variables in isaac sim physxSchema
PhysxSchemaPhysxVehicleAPI Class Reference (nvidia.com)

Can anyone know how to get it? Thank you.

Hi Vulcan.Shao,
Not sure about the connection to Isaac Sim. But on an omni.physx level, there are APIs to query these parameters, assuming you created a vehicle with an engine. See the method getVehicleDriveState() in IPhysX.h
