The work presents simulation models of the control and monitoring system, the study of the dynamics of the parameters of the elements of a hybrid car using simulation modeling in Matlab / Simulink environment is performed. A series-parallel drive of driving wheels is considered. The electric drive is carried out from an asynchronous electric motor. The model includes energy consumption regulation and control subsystems, calculation and state control of the battery, internal combustion engine, electric drive, mechanical model of the car, simulator of driver's influence on the fuel pedal, driving mode control system. The changes in the operating parameters of the hybrid vehicle components and the vehicle itself on the given driving modes are presented. The results obtained correspond to the real values for the selected class of cars.

Information about the parameters of the fuel supply is necessary to assess the operational and environmental performance and condition of the diesel engine of the car and tractor. To obtain such information, a special sensor is required, which is highly sensitive and is not built into the power system. The paper provides an analytical description of the processes in the overhead electromagnetic diesel fuel injection sensor. According to the selected electromagnetic circuit, an equivalent circuit is presented. Reasonable assumptions are made for the converter under consideration. Analytical dependences of electrical and magnetic parameters of a non-linear sensor circuit are presented. The conditions for obtaining the maximum sensitivity of the sensor are determined. An algorithm for calculating the magnetic circuit is presented. For the selected design parameters and operating current, the optimal frequency and supply voltage were determined.
