Nowadays, good distribution of electric vehicles and hybrid electric ones is reached. The article describes the prospects of development of medium cargo urban vehicles with hybrid powertrains using components manufactured in Russia. It also describes the advantages and disadvantages of the chosen scheme of powertrain. This requires good analysis and depends on type of the vehicle and key component features. The need to apply the test benches for experimental studies is justified. Also the aim of this article is to study a reasonability of key components manufactured in Russia. The authors describe the construction of an experimental vehicle with a hybrid powertrain. They also developed an algorithm of the vehicle operation with a hybrid powertrain during its movement in the urban cycle, which takes in the drive into account a power balance.

In this article the authors analyze various energy recovery systems of hybrid vehicles. Conclusions on inadequacy of existing technical solutions were drawn. The article also describes principles of selecting an energy recovery device that meets the performance level requirements of a hybrid vehicle. The authors describe the construction of an experimental vehicle with a hybrid powertrain. They also developed an algorithm of the operation of a vehicle with a hybrid powertrain during its movement in the urban cycle, which takes power balance in the drive into account. Results of the experimental research of a vehicle confirmed existence of limitations associated with a mounted energy storage device and electrical components. In addition, requirements for an "ideal" battery were specified.

The authors describe a project technology of solving multi-criteria parametric optimization problems in the field of motor transport. This technology is based on a two-stage approach. Stage 1 is optimization of performances of units and devices of a car, presented as a generalized description. Stage 2 is optimization of design parameters of units and devices of real designs. Performances of units and devices should be moved close to “optimal” ones obtained at the previous stage. Test items (two- and tri-axial cars) used for verification of the mathematical description are presented in the article. Application software STABCON 2.0 was developed for solving design and finishing tasks in the field of automotive industry. The software system is flexible and can be adjusted for solving design problems in the field of automotive technology beyond limits of controllability and stability properties. A designer can use previously created models. The authors draw a conclusion on the need for setting up a competence center for training industry experts and assisting them in solving optimal design tasks.
