The article deals with the study results of the quality of new cars in the production control process in the delivery condition to the consumer. The research was conducted on the basis of resource tests and using information-statistical analysis. The quality assessment of new cars and their role in customer satisfaction is given.

The article analyzes the approaches to the creation of the concept of a virtual test bench for testing the digital twin of the automotive industry product. Such components of the digital platform as suspension area, power plant, braking and cooling systems are being investigated. The problem of the implementation in the digital twin of such important units as the attachment points of units and assemblies on the vehicle body frame, even surface, driver dummy, the scheme of attachment of body elements, etc is studied. The importance of the implementation of such benches as platforms for assessing the indicators of the vehicle passive safety or as stand for assessing the water tightness of the vehicle body is considered. A number of results that illustrate development areas and success of the authors of the article in these areas are presented. It is shown that the digital platform can be used for certification and rating tests, assessing the comfort and visibility of the driver's cab.

The paper is devoted to the development of a method for optimizing the tread pattern to push aside the water from the road contact patch. This technique works with ready-made tread patterns of any type. Today, the methodology under consideration is relevant, since it prevents the occurrence of one of the most common causes of road accidents - aquaplaning. Currently, it is impossible to eliminate the risk of such an effect. It can only be reduced by slowing down or ensuring a uniform load on all wheels, trying to drive through the puddle with all four wheels.

The presented work is devoted to the problem of developing an electronic control system for the oxygen sensor heater of an automobile internal combustion engine.

The paper deals with the problem of assessing the characteristics of a vehicle body on the example of a car body. Such systems allow not only to reduce the cost of design, but also to obtain a number of important estimates that are not available at the stage of full-scale tests. An assessment system based on a virtual platform and a digital twin is considered. It is shown that the acceptable accuracy of the estimates is provided by the sufficient accuracy of the mathematical model. Considerations on approaches to designing the structure of such software systems are presented. The problems of modeling and evaluation based on the digital twin of the designed product are considered. The relationship between the model, on the basis of which it is supposed to evaluate the characteristics, and the models of adjacent vehicle systems, requiring a similar approach based on a digital virtual platform, is considered. Attention is paid to the main estimated parameters of the model and limitations.
