Modeling Transmission Systems and Vehicle Performance

SimDriveline provides sample transmission subsystems and vehicle component blocks.

Transmission Templates

SimDriveline provides models for the Lepelletier 6- and 7-speed, Simpson 4-speed, and Ravigneaux 4-speed transmissions. These subsystems can be used as templates to guide you in modeling your transmission systems. You can modify the topology of the model or values for gear ratios, shaft inertias, and clutch characteristics through the component blocks in the model.

The Lepelletier 7-speed transmission block masks the detailed model. You can use the standard transmission sample models as templates. Click on image to see enlarged view.

Vehicle Components

SimDriveline includes simple vehicle component models that let you model a complete powertrain and its impact on a vehicle’s motion performance. These models enable early evaluation of overall system performance. As with the transmission templates, you can add the detail required for your own powertrain and vehicle dynamics models.



Simple vehicle component models included in SimDriveline.

The Vehicle Components library includes the following:

• Gasoline and Diesel Engine blocks—for modeling the relationship between torque, engine speed, and throttle, with the throttle value assigned through a Simulink input signal
• Tire model—for evaluating the forces and moments associated with the tire-road interaction and calculating the rotational speed of the tire and wheel axle
• Longitudinal Vehicle Dynamics model—for evaluating the response of the vehicle to the accelerations and torques generated by the driveline
