Description

The utility model relates to automotive telecommunications devices designed to provide the driver with operational information about the location of the vehicle, about the traffic situation, as well as for conducting telephone conversations by mobile phone, including while driving.

As you know, an increase in traffic intensity leads to an increase in danger for both the person driving the vehicle and those around him. An increase in the number of cars leads to traffic jams and reduces the comfort of using vehicles due to time losses caused by these jams. The widespread use of mobile phones in everyday practice, the possibility of receiving and making phone calls, and making phone calls from a car makes the transport situation even more difficult, especially when drivers use mobile communications while driving.

The emergence of problems of ensuring comfort and safety in the conditions of intensive traffic and information flows has led to the appearance on the market of special telecommunications devices that combine the functions of navigation systems with global GPS positioning (Global

Position System), which provide the driver with information about the vehicle’s location, the most convenient driving route, etc., and hands-free devices (the so-called “hands-free” or “hands-free” devices), eliminating the need to hold a mobile phone in hand during a conversation . To notify drivers about the traffic situation, about the accumulation of vehicles on highways, about accidents, about the meteorological situation and much more, which is useful and necessary to know when driving a car, in a number of countries a TMS (Traffic Message Channel) service is offered in RDS standards ( Radio Data System) or RBDS (Radio Broadcasting Data System), implemented using FM (Frequency Modulation) radio stations that transmit special encoded information on the air at a frequency of 57 kHz with a speed of 1187.5 bps. Devices are proposed and implemented that make it possible to receive, decode and display this information for drivers of vehicles.

The well-known telecommunication devices, to one degree or another, solve the problem of providing drivers with the necessary information about the traffic situation, navigation, implement comfortable mobile communication conditions, however, the problem of the safety of drivers, their vehicles and surrounding people as a whole has not been solved. One of the reasons for this is that controlling these devices requires additional driver attention, distracting them from control of the road and traffic.

A car device for making speakerphone on a mobile phone is known (model "SK3100", technical description, issue V14 / 06/04, company Parrot S.A., www.say-parrot.com), comprising a main unit,

including the BLUETOOTH transceiver module, as well as an external microphone and a display unit electrically connected via cables, equipped with controls for making a call.

The disadvantage of this device is the inconvenience of its use while driving, due to the lack of the ability to use SIM (Subscriber Identity Module) card data of any BLUETOOTH mobile phone when receiving and making calls, as well as the need to manually select the subscriber's phone number using the controls located on the display unit, in which the driver is forced to remove his hand from the steering wheel and reduce control over the traffic situation on the road. In addition, this device does not provide the driver with operational information about the road situation, in particular about the presence of traffic jams and about the ways of optimal movement.

A universal automobile device for making hands-free calling on a mobile phone with BLUETOOTH is known (RF patent No. 45215, published 04/27/2005 with priority of 12/20/2004), containing a main unit including a BLUETOOTH transceiver module and also electrically connected via cables a remote microphone, a display unit, additionally equipped with a module for reading and storing data of the SIM card of a mobile phone, and a remote control optically connected to the display unit.
