01.08.2020

Every day the road can present new difficulties, but you will always save control over the car on complex coatings, lifts, winding roads and during unexpected maneuvers of other drivers thanks to the progressive electronic control system.

Feel absolute protected in Sorento Prime. The rigid power structure of the body is created with the use of high-strength steels, and six airbags are included in standard equipment. Highest level The safety is confirmed not only by laboratory crash tests, but also imitation of real collisions.

Circular Review Function 360 °

The system facilitates parking and maneuvering in limited space. Thanks to the four cameras, the display shows the view of the car from the height, which helps the driver to verify the surveillance of the situation from its angle in any direction during parking or maneuvers.

※ Working conditions: Inclusion, transmission lever in D / R / N positions, speed up to 20 km / h.

ESC (System currency stability) Controls the speed and direction of the car movement.

At the same time, the system constantly compares the parameters obtained from the sensors (ABS sensor, digging, acceleration, rotation of the steering wheel) with the driver's actions and manages the loss of the car's thrust, due to which drum can occur.

When the system (ESC) detects the loss of control, it instantly transmits an individual braking force on each wheel.

Anti-lock System (ABS) It ensures that friction does not lose with the braking between the wheels of the car and the road surface. When the driver suddenly hits the brake pedal, there is the likelihood that the machine will come out from under the control and rolling on the road. The main task of the anti-lock system is to avoid the emergence of such a situation.

Lifting Needed in cases where the car begins to move on an uneven road. The system ensures that the car does not roll back on steep rise, and has a number of significant advantages. First, with its help, the car on the rise is swept away from the place that the driver eliminates from the need to use parking brake. Secondly, the safety of both the driver and pedestrians enhances.

Principle of operation of the system such - when the driver ceases to harm the brake pedal, reduced pressure in brake system Begins to slow down gradually. The help system for lifting will come into effect when several factors match: the road rise will exceed 5%, the car will be headed, and the driver will prescribe on the brake pedal.

Kia Sorento. Prime is equipped with frontal and side airbags, protecting the driver and front passenger, as well as two security curtains that are serving to protect everyone who is in the cabin.

Emergency braking systemi need in order to in a dangerous situation on the road brake mechanism The car acted with maximum efficiency. According to statistics, when the system is running emergency braking braking distances Reduced by 15-20% percent. This is sometimes enough to avoid a serious collision, a crash or accident.

System BAS - by speed, with which the driver ride on the brake pedal determines whether the emergency braking situation was created on the road. The electronic control unit data on the speed of pressing the pedal is transmitted from the velocity sensor for the rod of the vacuum amplifier. In the case when the signal value moves for the established level of the norm, the stem drive electromagnet is activated. A vacuum brake amplifier begins to the brake pedal - so the emergency braking process is started. He begins to act earlier than aBS system.

Safety belt pretension system in emergency situations (EFD)

Seat belts on the front kia seats Sorento Prime is equipped with special EFD pretensioners. IN emergency situation Belts are stretched in advance, firmly holding the driver and front passenger in the chairs, which provides additional protection in the event of a collision.

Era-Glonass Emergency System

In unforeseen cases, the system will connect you to the operator to clarify whether everything is in order, or will cause emergency services.

LED headlights with dynamic near light function

Headlight headlamps can additionally highlight turns, providing better visibility in the dark. In addition, the rotating optics adapts to the corner of the rotation of the steering wheel, mass and velocity of the car.

In active head restraints A special mobile lever is built-in, which is located in the back of the chair. When the car faces an obstacle, the inertia pushes the driver in the chair, and its weight presses on this lever. In this case, the mechanism of opposition immediately begins to work - even before the driver's head leans back, the active head restraints are moved to it and soften the force of impact. After that they take initial position. It is worth noting that for the most efficient work, headrests must be previously adjusted.

The active head restraints come into effect when the machine faces an obstacle to a small or medium speed, as well as in some cases to drive to the car from behind. It is in such situations that the probability of injury increases due to the effect of "whip".

Integrated Active Control System (VSM) Helps the car to retain a stable position with simultaneous braking and turning the rotation, especially on a wet, slippery or uneven surface due to the collaboration of the stabilization and electric power steering system, based on the information collected by the sensors, the stabilization system and the steering power system will come into operation as soon as the car starts Slip and return it to a safe trajectory.

High Strength Steel (AHSS)

The Kia Sorento Prime design uses more than 52.7% high-strength steel. This unique steel grade is used to enhance the front, rear and side parts of the car, as well as in those bodies that experience maximum loads.

Rear subframe.

Hard rear subframe provides high resistance on the road.

Vertical rear shock absorbers

Vertical location rear shock absorbers It helps to smooth the negative effect from riding uneven roads and provides even greater comfort in the cabin.

Intellectual system automatic parking Spas.

This system is created to help you both with parallel and perpendicular parking. It automatically recognizes the suitable machinery, turns the steering wheel and evaluates the distance to other machines. All you need to do is press on gas and brake, and switch the transfers of your Sorento Prime.

Blind Zone Monitoring System (BSD)

The monitoring system of blind zones uses sensors that scan space on the sides and behind the car for the dangerous proximity of other vehicles in the zone of zero visibility. If the object is detected, the driver will notify the visual signal on the side mirrors and the central display. If the driver has turned on the turn signal, and another car is detected in the blind zone, the warning beep is turned on.

People are the most difficult link in a chain of events to unfold a new production system and the modernization of the old. Resistance to workers overcoming is easier than the middle link and top managers.

In the first All-Russian Forum "Leisure production for Russia" / 1 / was witnessed - almost two and a half hundred enterprises entered into the way of optimizing production and solve similar problems.

As the study of ICSI (Institute for Comprehensive Strategic Studies) "Distribution of LEAN Manufacturing Practice in Russia", it is the enterprises of black and non-ferrous metallurgy, as well as the entire spectrum of mechanical engineering led by a car industry are most prone to the introduction of "lean production".

Studying the Toyota production system (Toyota Production System, TPS), American analysts based on Japanese developments created their techniques, combining them in lean system Manufacturing or Lean Production. In Russia, she gained fame as Lin, she is "leaning production."

The most popular tools of "lean manufacturing" in Russia is quality management (69% of those who stated on the experience of the use of lin), elements of visualization of workplaces (30%) and reserves management (25%). Such a set, firstly, is due to the existing in the work of enterprises with narrow places. Secondly, these tools of Lin are relatively simple in mastering and implementation: they do not require preliminary transformations in production and can be implemented in a short time on separate pilot sections.

Figure 1 - Statistics Using Lin Technologies

Value Stream Map, VSM Flow Map is a diagram that displays each motion of the information streams of information necessary in order to fulfill the Consumer Order / 1 /.

VSM makes it possible to immediately see the bottlenecks of the technological flow and based on its analysis to identify all non-production costs and processes. Such cards are created on all pilot areas, and if you wish, it is not difficult to understand where and with what losses it is necessary to put up.

VSM is created in order to see the entire flow as a whole and give managers, technologists and the opportunity to speak in one language about the problems of different streams of flow. When building a VSM, you can see all the losses that are in the stream.

Since VSM reflects the stream status at a certain point in time, there are at least two types of cards of different states: the current state and status of the long-term perspective (future state).

Various software tools makes it possible to build VSM in graphical form, but the entire analysis of losses, bottlenecks, etc. It is not an automated process.

The concept of VSM is currently considered only on a narrow range of specialties, mainly on CAD specialties and various directions of automation of production. However, the use of this tool is possible in all places where there is a final product. For example, when creating a software product, configurations of accounting programs, assembling server OS, etc. The Internet offers a large number of remote and full-time training courses VSM and related technologies. But in many universities it does not attach attention.

Comprehension and description of the flow of value creation begins with a pencil sketch of the motion scheme of materials and information in the production process. After that, a map of the current state is obtained. This state is not perfect, on the map you need to search and note the bottlenecks for further upgrades. After that, the VSM process begins - the analysis process, which is to convert the current VSM card to the card of the future state.

Tools for VSM analysis are rarely used when learning the VSM concept itself. For some reason, it is believed that this tool is quite effective even with manual analysis, enough tools for drawing VSM schemes.

But there are several software tools that can help when analyzing. The most flexible and powerful among them is an add-in for Microsoft Visio, called EVSM. It allows not only graphically to make VSM cards, but also to calculate a large number of temporal parameters, the resource utilization ratio, time time, draw graphs of the process, numerically and graphically compare the results of certain changes in the scheme (to simulate the change results). This program is supplied as in a paid form (about $ 600) and in the form of a 30-day version and version for students.

In addition, the program provides the ability to solve and transport the problem (moving products between stages) with the use of "Spaghetti" -diagram.

Combining the VSM concept with EVSM type tools helps to study the creation management problems in more detail. various products In many areas of industry, small and medium businesses. And the teaching of these technologies specialties that are associated with the management of any processes of production or product creation will significantly increase the understanding of the optimization of such processes.

We think that when using such tools as EVSM, when training a wide range of future specialists to immediately instill them the foundations of "lean manufacturing" and the skills for analyzing real production processes.

Author Good, but I am also angry! asked a question in the section Choosing a car, motorcycle

What is an integrated active control system in a car and is it worth overpaying for it when buying a car? And got the best answer

Answer from F [Active]
Integrated car dynamics management system
VEHICLE DYNAMICS INTEGRATED MANAGEMENT, VDIM)
VDIM is an electronic car stabilization system in which all known systems are integrated. active security, steering amplifiers and engine management.
Having complete information about the current state obtained from the sensors located throughout the car, VDIM not only optimizes the operation of the anti-lock system of the brakes, the PACP holder system TopMoGo YCILI, the control and anti-infrared systems, but also improves the main dynamic characteristics car.
VDIM simultaneously controls power installation, Transmission and braking system in accordance with the conditions of movement, and also stabilizes the behavior of the car on a road surface with a low clutch coefficient.
The new dynamics management system is not so "intrusive" as the usual stability control systems, but it is much more efficient: if conventional security systems are activated immediately after the limit was reached technical capabilities Car, VDIM is activated long before the onset of this moment. As a result, the framework of the operation of active safety systems is expanding, and due to this, the softer and predictable behavior of the car is ensured, since these systems act more accurately, more softly and flexible

VSM complex at Hyundai Protein crossover will provide more confident car management in sophisticated conditions - on a wet, uneven or slippery road.

Modern cars Every year only adds to the number of electronics, becoming everything is technological, perfect and safer. AND new crossover Hyundai Cretage did not exception from the list. Set of management stabilization Hyundai Creta. - VSM system - also applies to the number electronic assistants driver.

Immediately it should be noted that this option is not in the list of basic equipment. It is only available for Krett in Active equipment (but only for versions with automatic transmission), as well as for top equipment Comfort.

Some terminology

The stabilization control complex is one of the ESC system elements (dynamic stabilization). The main task of VSM is to preserve the stability of the crossover under conditions of sharp braking or acceleration, when it occurs on an uneven, slippery and wet coating, since in such conditions, the degree of adhesion of the tires with the surface changes dramatically and unpredictable.

Briefly about ESC and VSM systems.

VSM work algorithm on Hyundai Cret

Activation of this complex on the parcktails occurs automatically when the conditions listed below:

Driver Krett rides on a winding road at a speed of over 15 km / h;
Activated a set of dynamic stabilization - ESC;
During braking on uneven coating, the speed of the krett exceeds 20 km / h.

However, it is worth remembering when the VSM system will not work:

Riding a reverse;
Movement under the condition of the disabled ESC complex - in this case the ESC OFF EXC indicator is on;
During the descent or lift;
If the electric power steering wheel - EPS flashes or flashes.

It is also necessary to take into account that in the process of the operation of the VSM complex, a specific sound can be heard. And the brake pedal flies. These are signs of the system's correct operation and they are not evidence of malfunction.

The benefit from the VSM complex is obvious.

Activation and deactivation of VSM

To enable the VSM Hyundai Craft system, you must press the ESC OFF key. At the same time, the control lamp ESC Off goes out. To disable the specified complex, you need to press the key again, as a result of which the ESC OFF indicator will light up.

However, it is necessary to be attentive, since if the ESC and EPS system indicator does not go out, there is a possibility of the release of the VSM complex. In this case, it is strongly recommended to move the cape to the diagnosis in the Dealer Center Hyundai.

Precautions

The presence of the mass of electronic systems in the car can play and evil joke with the owner. Negative side It is that the Krett winner begins to rely too much on electronics, neglecting precautionary measures during a ride.

IMPORTANT TO REMEMBER - Electronic systems Are not unconditional guarantor of security.

Nevertheless, it is clearly not worth it for electronics.

This means that the presence of a VSM complex of the VSM complex does not mean that it is possible to straighten with impunity. By itself, the VSM system is not able to prevent an accident. Therefore, it is always necessary to observe the distance to traveling ahead of the car and not exceed the speed allowed by the rules. Especially relevant in bad weather, on an uneven, wet or slippery road.

Separately, it is worth noting the moment associated with the wheels of Hyundai Prost. They must be the same. In case the crossover bus or discs differ in size, the VSM system may not work correctly. Therefore, it is extremely recommended to ride with different wheels, especially if we are talking about a long trip.

This system provides an additional improvement in the stability of the vehicle and the reaction on the steering wheel when moving on a slippery road or detect changes in the friction coefficient between the right and left wheels during the braking process.

Working system VSM.

During VSM, it is possible to control the steering wheel. If the VSM system functions normally, light ripples are felt in the car. This is the result of brake management and does not indicate a malfunction.

The VSM system does not function in the following situations:

Turning off the VSM system

To turn off the system, press the ESP OFF button, the ESP OFF () indicator will also light up.

Fault indicator

The VSM system can be deactivated automatically (in addition to pressing the ESPOFF switch). Such automatic deactivation indicates a malfunction in the power steering system with electronically control (EPS) or VSM system. If the ESP () indicator or the EPS control lamp continues to burn, refer to the authorized KIA dealer to check the system.

FOR YOUR INFORMATION

The VSM system is designed to facilitate the passage of turns at speeds of more than 15 km / h (9 mph).
The VSM system is designed to facilitate braking on roads with inhomogeneous coating at speeds of more than 30 km / h (18 mph / hour). The coating of such roads is made of materials with different friction coefficients.

CAUTION

The stabilization control system (VSM) cannot replace good safe driving, and is only an additional feature. The driver is obliged to always control the speed and distance until the coming vehicle is ahead. During the movement, always hold the steering wheel.
Yours vehicleEven when installed system VSM, always listens to the driver. Always observe the usual security measures when driving, including the selection of speed according to the road situation, including when rainy weather and with slippery road surface.
If the car is installed on the car or tires of various sizes, the VSM system can function incorrectly. The dimensions of the replacement of tires must be the same as the original tires.
