Transmission and Drivetrain

Transmissions, torque converters, differentials, and controllers

In powertrains, the transmission and drivetrain comprise the driveline. Transmissions convert engine torque to drive shaft torque. Drivetrains convert the drive shaft torque to axle torque. Use the transmission and drivetrain blocks to assemble drivelines for torque capacity sizing and gear ratio impact on performance.

Featured Examples

Conventional Vehicle Reference Application

Conventional Vehicle Reference Application

Simulate a full vehicle model with an internal combustion engine, transmission, and associated powertrain control algorithms. Use for powertrain matching analysis and component selection, control and diagnostic algorithm design, and hardware-in-the-loop (HIL) testing.
