Control of Hybrid Power Unit with a Mechanical Transmission in High-Speed Caterpillar Vehicles

Abstract

The properties of a hybrid power unit in which a mechanical transmission rigidly connects the internal combustion engine to the driving wheels are considered. In this transmission, the torque created by the parallel electric field is summed with the torque generated by the engine in the event of overloading. The control algorithms developed for the electric power prevent its opposition to the mechanical power under any circumstances.
