Mechanical Simulation Adds Electric Powertrains for CarSim and TruckSim 2019.1
ANN ARBOR, Mich., July 25, 2019 – Mechanical Simulation Corporation has released the 2019.1 versions of the vehicle dynamics simulation tools CarSim and TruckSim, which are well known for providing high-fidelity math models that reproduce physical test results, yet run fast enough on the computer to support real-time simulation with hardware in the loop.
CarSim and TruckSim support many options for extending the vehicle models, and those options have been used in the automotive industry to interface VehicleSim products with external powertrain models, in addition to the built-in model with an internal combustion engine with traditional transmissions, differentials, and clutches. As electric and hybrid powertrains have become more popular, Mechanical Simulation has been adding support for electric and hybrid powertrains as part of the built-in model options.
According to Dr. Yukio Watanabe, Senior Development and Consulting Engineer, “Given the use of electric and hybrid powertrains, there is a need for vehicle simulations to represent newer powertrains without requiring additional software.” The more recent releases of CarSim and TruckSim have provided increasing support for electric powertrains. Version 2018.1 included a validated Simulink model for a hybrid powertrain that made use of an improved interface between the native vehicle model and external models made in Simulink. In version 2019.0, the same hybrid math model was included as a built-in module for the vehicle model. In the new 2019.1 release, the built-in module was extended to simulate electric-only powertrain.
CarSim and TruckSim users can now choose between three different built-in powertrain system modules: conventional internal-combustion engine, pure electric motor, or a hybrid of those. Watanabe notes that “the new capabilities enable CarSim/TruckSimusers to predict detailed battery usages with re-generative brakes under fuel economy tests such as EPA driving cycles.” The model specifies motor torque characteristics, the number of battery packs, battery open-circuit voltage, etc. with moderate power management controller.
