ANALYSIS OF THE USE OF A HYBRID DRIVE SYSTEM IN URBAN TRAFFIC CONDITIONS

Abstract

The continued reduction of fuel consumption by vehicles leads to an increase in the share of hybrid and electric vehicle drives in the automotive market. There are many approaches, such as to focus only on the introduction of electric vehicles, however, using this type of drive requires additional infrastructure, reconstruction of many systems and has a long charging time, with which consumers are not entirely satisfied. Therefore, one of the leading types of passenger car drives is currently a hybrid drive. It does not require reconstruction of the entire infrastructure, only changes in vehicle drive systems. The costs related to this are relatively small compared to, for example, the construction of a network of new charging stations. Knowing the electric drive operating share in a vehicle with a hybrid system is used as a determinant of the profitability of using electric drives. The article estimated the share of electric and hybrid mode operation in urban traffic conditions. The research object was a Toyota C-HR vehicle equipped with a fourth generation hybrid drive. The analysis of the drive's operation allowed to determine the conditions of energy flow and determine the share of electric mode operation in the total driving time and in relation to the distance travelled.
