According to one embodiment of the present invention, the deceleration information generating unit 130 may generate deceleration information on deceleration of the vehicle speed based on the strength of the speed sensing signal. For example, the deceleration information generating unit 130 can confirm that the external device 200 and the vehicle 1 are close to each other as the intensity of divergence from the external device 200 decreases. Also, the deceleration information generating unit 130 may generate deceleration information for decelerating the speed of the vehicle at the moment the intensity of the speed sensing signal emitted from the external device 200 is sensed. When the deceleration information generating unit 130 detects the speed sensing signal emitted from the external device 200, the deceleration information generating unit 130 generates the deceleration information, Can generate deceleration information for deceleration of the speed of the vehicle 1. [

The deceleration information generating unit 130 may be configured to decelerate the vehicle 1 using the deceleration information as a priority when the speed limit information of the speed storage unit 160 is greater than or equal to the information obtained from the plurality of vehicle deceleration information providing apparatuses 100. [ Lt; RTI ID = 0.0 > deceleration < / RTI >

3, the deceleration information generating unit 130 generates the deceleration information using the speed and distance of the first vehicle 2 that is running in front of the automobile 1 and the speed and distance of the second car that is running in the rear of the vehicle 1. [ (Not shown) that detects the speed and distance of the vehicle 3 based on information provided from a vehicle detection unit (not shown).

According to an embodiment of the present invention, a vehicle sensing unit (not shown) may sense the traveling speed of the first vehicle 2 running in front of the vehicle 1. [ In addition, the vehicle sensing unit (not shown) can sense the distance between the vehicle 1 and the first vehicle 2 running in front of the vehicle 1. In addition, the vehicle sensing unit (not shown) can sense the traveling speed of the second vehicle 3 running in the rear of the vehicle 1.

The deceleration information generating unit 130 generates deceleration information on the basis of the distance between the first vehicle 2 and the vehicle 1 in order to prevent collision with the first vehicle 2 running in front of the vehicle 1, Lt; / RTI >

The deceleration information generating unit 130 can not detect the forward situation when the situation is on the foggy road, so that it is possible to generate safer deceleration information than the deceleration information on the day when the fog is not present. In other words, the deceleration information generating unit 130 can generate the deceleration information for performing the decelerating driving within a predetermined range of the distance of the external device 100 at the days when the safety braking distance is required longer than the clear day have.

According to one embodiment of the present invention, the deceleration information generating unit 130 may generate deceleration information on deceleration of the speed of the vehicle 1 based on the car information of the car 1.

[ The deceleration information generating unit 130 may generate deceleration information of the automobile 1 based on the predicted degree of tire wear. For example, when the tire is replaced on the same day, since the degree of wear is not so severe, information for starting deceleration from a position located within a certain area from the external device 200 can be generated. On the contrary, if the tire replacement period is long and the distance traveled after the tire replacement period is long, the tire wear is serious and the braking distance may be long. Therefore, information for starting the deceleration from the external device 200 Can be generated.

The deceleration information providing unit 140 may provide the deceleration information generated by the deceleration information generating unit 130 according to an embodiment of the present invention. The deceleration information providing unit 140 may provide the deceleration information generated by the sound output or the display output based on the generated deceleration information.

The position detection unit 150 may provide the detection result to the deceleration information generation unit 130 and the deceleration information providing unit 140.

According to another embodiment of the present invention, the position detector 150 may estimate the speed of the vehicle based on the position information of the vehicle sensed by the GPS. The position detection unit 150 can detect the position of the automobile 1 at specific time intervals and estimate the speed of the automobile 1. [ The position detection unit 150 may provide the estimated speed of the automobile 1 to the speed sensing unit 110, but the present invention is not limited thereto.

According to one embodiment of the present invention, the deceleration information generating unit 130 may generate map data and traffic condition data corresponding to detection results of the current position value, moving speed value, moving direction, etc. of the car received from the position detecting unit 150, Lt; / RTI >

Since the speed storage unit 160 receives the map data for the current location of the vehicle from the server even if the 2D or 3D map data for all the areas is not stored by receiving the data from the external server in real time, The storage space can have an unnecessary advantage.

The traffic condition data corresponding to the detection result of the current position value, the moving speed value, the moving direction, etc. of the automobile may include traffic information (e.g., traffic congestion period, A bundle area, a movable intermittent camera installation area, a fixed intermittent camera installation area, and the like), and can provide the latest traffic information for the area where the vehicle is currently located.

According to one embodiment of the present invention, the speed storage unit 160 may be a database storing limit speed information corresponding to an area set by a specific radius from the current position of the vehicle. The speed limit information may be illustratively a portable type vehicle installed in a specific radius (e.g., in the form of a circle having a constant radius of 100 m, 300 m, 500 m, 2 km, or the like, Or the data of the position of the fixed intermittent camera, the shooting direction of the intermittent camera, or the speed limit of the current position of the vehicle.

In addition, the speed storage unit 160 may update the position information of the external device 200 by storing the speed sensing signal sensed by the signal sensing unit 120 in correspondence with the GPS position information. In addition, the speed storage unit 160 stores information on real-time traffic conditions (e.g., congestion zone, accident occurrence area, accident bundle area, movable intermittent camera installation zone, fixed intermittent camera installation zone, etc.) May be updated.

The deceleration information generating unit 130 determines whether the moving speed of the vehicle detected through the speed sensing unit 110 exceeds the previously stored limit speed in the speed storing unit 160 and then determines whether the current moving speed of the vehicle The deceleration information for decelerating the speed of the vehicle can be generated when it is determined that the speed limiter 160 has exceeded the previously stored speed limit. Illustratively, the deceleration information may be a phrase indicating the speed limit of the current position and information on the running speed of the current car. In other words, the deceleration information may be information that allows the driver to grasp the speed limit of the current position and the speed of the vehicle, such as the speed limit of the current position: 80 km, the speed of the vehicle: 100 km, and decelerates.

According to an embodiment of the present invention, the storage unit (not shown) associates the speed sensing signal detected by the signal sensing unit 120 with the position information of the GPS for acquiring the position information of the vehicle 1, The location information of the mobile terminal 200 can be stored. The storage unit (not shown) stores and updates the position information of the external device 200, so that it is possible to provide more accurate timing of the deceleration information when the occupant of the automobile 1 travels a lot.

According to one embodiment of the present invention, the deceleration information providing unit 140 may provide the generated deceleration information to the control module of the vehicle 1.
