ABSTRACT
This article sets out the tasks for monitoring the operational characteristics of vehicles. In addition, the longevity of
the car, the suitability for loading and unloading, ease of loading and unloading of passengers, the level of safety, the
reserve of the vehicle in the distance before maintenance or repair, the complexity of these works, the number of
seats for passengers convenience, protection of the div or cabin from rain and dust, heating and ventilation
efficiency, noise reduction and other similar indicators.
KEYWORDS

INTRODUCTION
The technical readiness of any product can be assessed
by comparing it with the technical readiness of
something else similar. In the same way, the readiness
of each vehicle to operate can only be compared with

other vehicles of the same size and type. You can’t
compare in terms of the performance of the
structures, for example, a van designed to lift light
loads and a self-propelled dump truck for lifting heavy
loads.
There are a large number of different performance
indicators of vehicles that can be considered
independently. E.A.Chudakov recommended 13 of the
following performance indicators of vehicles:
dynamics, economy, reliability, manoeuvrability,
stability, easy handling, smooth movement, simplicity
of maintenance, capacity, walking reserve, usability,
usability and manoeuvrability. In addition, for example,
the longevity of the vehicle, its suitability for loading
and unloading, ease of loading and unloading of
passengers, the level of safety, and the reserve of the
vehicle in the interval before maintenance or repair.
THE MAIN PART
During operation, the technical readiness of the
product or material changes as a result of specific
changes in the product (vehicle, unit, part) or material
(fuel, oil, etc.) and changes in its constituent elements.
For example, fuel consumption during transportation
depends not only on the operating conditions or the
design of the car but also on the current state of the
car's ignition and fuel supply system, the degree of
wear of the cylinder-piston group, the angle of
installation of the front wheels. and so on. Therefore,
in the implementation of the purposes of road
transport and its technical operation, the technical
condition of vehicles, the reliability of which is
interrelated with the above concepts of technical
operation: technical condition, operation, reliability,
technical readiness, consideration for a comprehensive
assessment of the target scheme is very important.
Technical readiness is a set of features that determine
the suitability of a vehicle, process equipment, unit,
part, or material for a specific purpose, to the extent
that it can perform the tasks assigned to it during its
operation. Technical preparation consists of several
features (Figure 1). Each feature is characterized by one
or more parameters called indicators and which can
take different quantitative values during operation.
In analyzing or evaluating quality, the following chains
are considered in sequence: in product evaluation and
testing: indicators – parameters features - technical
training;
After submitting the requirements to the products:
technical readiness - features - parameters - indicators.

Figure 1 The logical structure of the concept of technical training
Fig. 1 shows examples of four quality characteristics
indicators. Thus, one of the parameters of the fuel
efficiency (feature) of the car is to control the fuel
consumption, which has a quantitative value of 71/100
km (indicator) for this particular model.
The following basic technical and operational
characteristics (M) of cars are usually considered:
Load-carrying capacity;
Dynamics (gravity-velocity property);
Capacity;
Manoeuvrability;
Productivity;
Security;
Reliability.
Technical
and
operational
characteristics
are
determined during the design and production process;
are carried out at different stages of the production
and operation process. In this research paper, we
explore features such as fuel efficiency, dynamics
(average maximum speed), productivity, and
durability. Based on the monitoring of these features,
a system will be developed to assess the feasibility of
the interaction of vehicles with operational and
technical measures. All currently known methods of
planning the periodicity of maintenance (M) of
individual units and components of the car can be
divided into 3 groups.
Simple - by changing the appearance of the object
(method of analogy and comparison);

Statistical - according to the allowable level of
probability of trouble-free operation (feasibility,
economic and probability and statistical test
method);
On the allowable value of changes in the technical
parameters of the object.
An analysis of the available methods for determining
the periodicity of maintenance shows that all of them
are designed to perform the method of maintenance
and repair according to the operating time, ie.
CONCLUSION
According to the analysis, the most promising method
that requires future development is the statistical-test
method. Using this method, it is possible to schedule
the optimal periodicity of the M for each vehicle on a
computer. In addition, the statistical test method also
allows determining the optimal periodicity of
maintenance and current repairs (M and CR) to
diagnose the technical condition of individual elements
of the vehicle to prevent inefficient operation of
vehicles.
