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.
Putting complete information About the current state obtained from the sensors located throughout the car, VDIM not only optimizes the operation of the anti-lock brake system, the PACP hold system of TopMoGO YCILLY, bonus and anti-chassing 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 the usual security systems are activated immediately after the limit of the technical capabilities of the car, VDIM is activated long before this moment has been achieved. 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

One of the main problems facing automakers is to improve the safety of the car, including in the process of movement. For this, the car is equipped with various devices that help the driver to cope with the control in the most difficult situations. One of them is an integrated VSM active control system.

About forces and moments

The torque developed by the engine enters the wheels, and the car begins to move. So very simplistic, you can describe the process of moving it. However, at the beginning of movement, maneuvering and braking, a variety of forces affect the car, and the nature of their exposure depends on the speed, the state of the road and the actions of the driver.

Sometimes these actions are erroneous and incorrect, which may be an accident. To avoid this, the developers are invented not one electronic deviceproviding assistance to the driver in difficult conditions. Without touching them all, it is enough to mention the most famous and all for hearing everyone:

  • ESP - a course stability system (from different manufacturers It carries a different name - ESC, DSC, DTSC, etc. In the future, the text will be used the most common ESP abbreviation);

The operation of any of the similar devices of active control is based on constant control of signals from sensors. According to them, the controller is determined by the inconsistency of the real mode of movement of the car to what should be, they also take the necessary measures, for example, it resets the speed, slows down or unlock the wheel, changes the engine operation mode.

VSM active control system

It is worth mentioning another, somewhat specialized, but useful integrated VSM control system. It does not work by itself, only complete with ESP and ABS. If ABS provides stability when braking, TCP during acceleration, ESP prevents lateral displacements and is engaged in stabilizing the position of the car during maneuvers, then the VSM system as it were as an integrated, combining all other nodes and driver actions.

The VSM system combines the steering motor, ESP and ABS. As the manufacturers of auto with VSM declare, the stabilization control system opposes the erroneous acts of the driver, i.e. If the critical situation is performed in the critical situation to control the car, the VSM will counteract them.

In a more understandable presentation, this means that if the driver, when performing a maneuver, turns the steering wheel not to the other side, it will require significant efforts. Whereas, with the right steering, nothing like that does not happen.

Tasks that vsm solves

If you try to summarize which tasks a similar integrated system solves, the following can be noted:

  1. relief effort on the steering wheel in parking and maneuvering at low speed;
  2. increase at high speed of the steering wheel torque;
  3. an increase in the reactive force of the wheels when they return to the middle position;
  4. adjustment of the position of the front wheels when driving on the road with a slope, lateral wind, the difference in pressure in wheels;
  5. improving stability (coursewa).

Thus, the stabilization of the position of the car on the road during the movement, the VSM system is engaged in the same way as ESP, ABS and other similar to the device assignment. The difference between them will be that VSM through an electromechanical amplifier has an impact on steering wheel, not on the brakes. In other words, the effect on the steering wheel and brakes is combined.

This is especially true when overclocking or braking on different surfaces (one wheel on ice, water or other coating, other on asphalt). As a rule, as a result, the car begins to pull away. To correct the situation on the steering mechanism, control signals are fed by adjusting the position of the car. In principle, the considered situation is typical for the operation of a similar management system. The possibility of driving may be repeated with sharp maneuvering, in which case VSM will also help keep the car from driving.

It should be noted that such a device is not included in standard complete set car.

Such an active control system as VSM, primarily ensures the stability of the car on the course, when it is moved along the different coating under different wheels. In this case, not only signals to slow down the individual wheel are formed, but also on steeringThanks to which the car continues to move at the specified course, and it is possible to avoid its drift.

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

Feel absolute security 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 (Curriculum System) 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 safety airbags that protect the driver and front passengerAs well as two security curtains serving to protect everyone who is in the cabin.

Emergency braking systemi need so that in a dangerous situation on the road braking mechanism of the car acted with maximum efficiency. According to statistics, when operating an emergency braking system, the brake path is 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. IN the electronic unit Control 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. The brake pedal begins to influence vacuum amplifier Brakes - so the emergency braking process is launched. He begins to act earlier than aBS system.

Safety belt pretension system in emergency situations (EFD)

Safety belts on the front seats KIA SORENTO PRIME are 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 the 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

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

Intelligent SPAS Auto Parking System

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 to others. vehicle in zone 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.

One of the main problems facing automakers is to improve the safety of the car, including in the process of movement. For this, the car is equipped with various devices that help the driver to cope with the control in the most difficult situations. One of them is an integrated VSM active control system.

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 manufacturing toyota system (Toyota Production System, TPS), American analysts based on Japanese developments have created their own techniques by combining them into the LEAN Manufacturing or Lean Production system. 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 VSM concept with EVSM type tools helps to study the problems of creating 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.
