The paper describes the concept of a wheeled vehicle control system with a hybrid powertrain in SiL (Software in the Loop) technology using the NI LabVIEW software. The modeled control system has been constructed based on a mathematical model of a wheeled vehicle and the mathematical models of powertrains. The control of powertrains is provided with type PI controllers for the internal combustion engine and the linear-quadratic regulator (LQR) for the DC motor.
