Audi experts assume that in the future, about 90 percent of innovations related to the car will be implemented on the basis of a key technology - electronics. In the car of the future, intelligent systems will exchange information in real time. Through the Internet, the car will be connected to the whole world, through numerous sensors it will receive data on its surroundings, and at the same time, driving will remain uncomplicated.

Onboard power grid in development
The introduction of innovative ideas is gradual, many of them have already been implemented, others are being implemented with an interval of several months. For example, already in the middle of 2001, the collection of electrical circuit diagrams of Audi included some circuits that will only be valid from 2002.
New principles of power supply are being intensively developed. In today's 12-volt production car, the battery is the result of a compromise. The battery is designed both for starting the engine and for supplying consumers. However, the requirements that must be met in this case partially contradict each other. During the start of the engine, the battery must deliver a current in the range from 300 to 500 amperes, that is, provide more power, while various devices that include microprocessors can suffer from a decrease in voltage.
Onboard network of the future: Separate batteries provide reliable stable start-up and uninterrupted power supply. The charging-decoupling module prevents voltage drops when starting the engine and discharging of the battery due to consumers. 1 - lighting installation (onboard network), 2 - starter, 3 - engine control unit (onboard network), 4 - starting battery, 5 - other consumers (e.g. sliding roof control), 6 - supply battery, 7 - generator, 8 - charging-interrupting module.
It is difficult to create a battery that would satisfy these two requirements. In the future on-board network, these functions will be divided between the starting and supply batteries. Thanks to this, a reliable cold start will be ensured even with a charge of the supply battery of only 30%.
However, the future on-board networks of Audi vehicles will primarily be distinguished by the presence of the MMI multimedia interface. This interface provides comfortable control, it combines the various controls of individual systems with one logic. All this creates the prerequisites for controlling future complex systems without lengthy preliminary driver training.
control with multimedia interface on the center console: Key 1 is used to directly select the main functions, selection is made using the turn control 2 The four corners of the display correspond to the four keys 3 that are located around the control. Reset is carried out using key 4.
The advances that have been made in networking, as well as a powerful processor for menu-driven control, allow the interfaces of all components to be combined in one place.
This remote control concept will work on the principle of space-separated placement of indicator elements and controls. For the most important menus, there are four pairs of specially fixed (physical) keys, four programmable keys, depending on the context, allow you to jump to individual sub-functions. The key element for all functions is the master turn/push button. The control panel between the shift lever and the armrest in the middle of the seat provides the driver with a comfortable (blind) control.
Two high-resolution color displays are used as indicator elements. One is located in the middle of the combined instrument panel and the other (bigger size) - in the upper part of the middle console. Both displays are in the driver's primary field of vision.
Due to the importance of temperature control, a separate control was deliberately chosen to control the air conditioner, however, this element was created on the basis of the same simple and understandable logic.
Telematics opens up new possibilities
The navigation system is more and more flexible and adapted to the needs of the driver. In addition to current services such as automatic emergency call in the event of an airbag deployment and dynamic route guidance using a navigation system, the introduction of an information service is envisaged as the next step in the development of telematics. This service allows the driver to contact an Audi service center at the touch of a button.
When planning a route in the memory of a special device, you can store data on several (up to five) information points. With the introduction of a new generation of devices that use the achievements of telematics, Internet technologies and their corresponding standards are beginning to be used in the car. Based on the services known today, new services are being created that are based on the use of Internet technologies. The far-reaching integration of telematics and automotive electronics promises to bring big returns.

Don't be afraid of electronics!
True, so far you have to deal with parts that have been installed in a car throughout its history: a battery, a starter and a generator. Together they are responsible for starting the engine. When performing a joint task, these details depend on each other. Without a battery, the starter does not rotate, without a starter, the engine and generator do not work, without a generator, the battery cannot be recharged.
The current is produced in the engine room and the working conditions are not ideal. Sometimes it's cold in the engine compartment, sometimes it's hot, often it's not only humid, but really damp. Therefore, current sources (battery and generator) sometimes become a source of irritation. Since many consumers of electricity are located in unprotected places, their malfunctions inevitably occur. In view of the foregoing, it is not so rare to work with electrical equipment. Despite the complexity of this equipment, you should not lose heart if nothing happens when you press a switch. Often the cause of the defect is a loose wire or a corroded contact. Many faults can be fixed by simple means, even if you are not a professional electrician. Naturally, you need to know something from electrical engineering, so we will explain some concepts to you and give you appropriate recommendations.
