Cars with an internal combustion engine consume a large amount of fuel and emit harmful substances into the environment with exhaust gases. The ecology problem is especially acute in large cities and near federal highways. At the same time, emissions from automobile transport are growing at a faster pace, and its share in emissions of harmful substances from the transport complex is 89%, because the number of cars is increasing annually. One of the effective directions in solving the problem is the use of electric drive in car designs [1,2]. In transport engineering, such companies as FordMotors, GeneralMotors, Chrysler, Reno, Fiat, Pegeot, Volkswagen, TokyoElectricPowerCo, AseaBrownBoveri and others are engaged in the development of electric drives used in cars and their electrical equipment. [3,4,5]. An example is the development of Volkswagen. This car consists of a diesel engine, a small electric motor and a sodium sulfur battery. When driving at low speeds, the drive wheels are driven by an electric motor, then the internal combustion engine is launched, which provides wheel drive at steady speeds. In this case, the electric motor goes into generator mode. The prototype allowed consuming 4 liters of fuel per 100 kilometers and reducing the toxicity of exhaust gases by 60% compared with a serial internal combustion engine. A hybrid car has two energy sources: an internal combustion engine and an electric motor. Each of the engines complements the disadvantages of the other. In this case, the energies of two engines are combined. The matching element or summing reducer can be various types of reducers: chain, belt, gear, planetary, etc. When summing the energy of two engines, it is necessary to coordinate the rotational speeds of the shafts of the internal combustion engine and the electric motor, which are interconnected via a summing reducer.
