The present invention relates to a vehicle GPS receiver having a hands-free function, and in particular, by connecting a mobile phone to a vehicle GPS receiver to enable hands-free calls, a separate phone call for a mobile phone to a vehicle equipped with a vehicle GPS receiver The present invention relates to a GPS receiver for a vehicle having a hands-free function by which a mobile phone call can be made using an additional function of the vehicle GPS receiver, thereby increasing the user's convenience.

In recent years, the use of mobile phones has been explosively increasing, and due to the widespread use of automobiles, mobile phones are frequently used when driving a car.

However, because using a mobile phone while driving could cause a safety accident due to the driver's declining concentration, the driver had to use the cell phone very carefully while looking ahead.

In order to alleviate this inconvenience, a hands-free device has been invented that allows a driver to make a phone call while not driving by hand while driving.

The hands-free device is to make a phone call with the other party using a speaker or the like without holding the mobile phone by hand.

1 is a perspective view showing an example of an automobile hands-free device of a conventional mobile phone, wherein the hands-free device includes a cradle 2 on which the mobile phone 1 is mounted and a hands-free main body 4 for controlling the hands-free function to be performed. It is included.

The hands-free main body 4 is connected to a speaker 8, a power cord 5 receiving power provided from a vehicle, a cord 3 connected to the cradle 2, and the like.

The cradle 2 is installed at a position (for example, an instrument panel position close to the driver's seat) where the user can conveniently mount the mobile phone 1 in a vehicle interior, and the mobile phone mounted on the cradle 2. Between (1) and the holder (2) is usually connected by a curl cord (curl cord) (6), the mobile phone (1) and the curl cord (6) is to be connected and disconnected.

Meanwhile, recently, a GPS receiver which receives a GPS signal in a vehicle and uses traffic information has been widely used.

This is to be associated with the vehicle navigation system to warn when a car is close to a point of caution when driving, such as an accident-prone area or a sharp curve area, on the road.

GPS is short for Global Positioning System. It uses satellites floating in orbit around the earth to provide accurate location and time regardless of weather. It is also called satellite positioning system.

The GPS receives the navigation messages from the satellites and determines the location by calculating the location at the receiver. Since four or more satellites are always located in the field of view at all times on Earth, the user can select the appropriate four of these satellites. It selects and receives the time signal from them and measures each distance.

Since the positions of the four satellites are known, the three-dimensional position of the user's latitude, longitude, and altitude and the visual deviation of the clock can be known from this measurement.

The transmission frequency from the satellite is two waves of L1 (1,575.42 MHz) and L2 (1,227.6 MHz), and the navigation signal uses CDMA (Code Division Multi Access) method including navigation information of 50 bps (speed of sending 50 bits per second). use.

In other words, the receiver needs to know from which satellite the signal it received comes from. Since each satellite carries its own data at the same frequency, it cannot be distinguished by the frequency and is identified with the independent ID assigned to each satellite. .

The receiver has the IDs of all the satellites, and when a signal comes in, it finds a matching ID among the IDs it has, and obtains navigation data from it and calculates its position.

Each satellite simultaneously generates two different frequencies L1 and L2. The information superimposed on these two carriers consists of PRN (Pseudo-Random Noise) codes and navigation messages. This PRN code is divided into P code and Coarse Acquisition (C / A) code. The C / A code is also known as a private signal and can be used by individuals or groups that are not specifically authorized, but the P code is encrypted. You need permission to use it. The L1 carrier carries the C / A and P codes, and the L2 carrier carries only the P code.

GPS has been applied to many parts, and in the mobile communication field such as a mobile phone, it shows its location along with a map, and provides information such as various traffic, shopping, and restaurants nearby, and also saves lives. It is used in emergency situations, and it is also used in car navigation systems that allow users to find the place they want to go through the navigator attached to the car. In addition, it is widely applied to military and aviation control.

Such a GPS receiver typically includes a GPS engine unit for receiving GPS satellite signals, a memory in which a traffic information database is embedded, a notification unit for audibly or visually notifying when a specific signal is received from the GPS engine unit; A central processing unit connected to the GPS engine unit, a memory, and a notification unit, respectively, and having a program embedded therein to control the entire system; It is composed of a power supply unit for supplying power to the central processing unit.

Therefore, in the case of installing a vehicle GPS receiver in a vehicle, although a hardware element that can be used as a hands-free device is provided, a separate hands-free device must be installed for a convenient mobile phone call. Due to such hands-free devices and cables connecting them, the front part of the vehicle is complicated, and there is a problem that can lead to confusion in its operation.

The present invention is to solve the above-mentioned shortcomings, without having to install a separate hands-free device for the call of the mobile phone in the vehicle equipped with the vehicle GPS receiver, so that the mobile phone call can be made using the additional function of the vehicle GPS receiver Another object of the present invention is to provide a GPS receiver for a vehicle having a hands-free function that can increase user convenience.
