Hereinafter, a travel guidance system according to an embodiment of the present invention will be described.

1 is a schematic view showing a main configuration of a travel guidance system according to an embodiment of the present invention.

1, a travel guidance system 100 according to an embodiment of the present invention includes a road information collection device 10, a user terminal device 20, a travel information providing device 30, and a communication network 40 Lt; / RTI >

The road information collecting device 10 collects road surface information of a road during a vehicle operation through various devices installed in the vehicle and provides the collected information to the driving information providing device 30 in real time.

Here, the road surface information collection process will be described in more detail.

Generally, roads on roads have good roads. On the other hand, there are roads with good roads. On the other hand, there are roads with slippery roads due to rain or snow, slippery roads due to environmental and local influences, It maintains various conditions such as road surface.

As described above, when the road surface is not good, the frictional force between the tire and the road surface is reduced, so that the normal vehicle braking control is not performed, thereby causing a serious accident such as a collision with a nearby vehicle.

Therefore, the vehicle is equipped with a device such as an electronic stability program in order to prevent the vehicle from being operated differently from the driver's intention when the vehicle is running.

Such a driving safety device independently controls each of four wheels instantaneously in order to maintain stability when the vehicle tries to slip, thereby enhancing the stability of driving on a dry road surface, a comb, a cobbled road, and an eye path.

For example, an anti-lock brake system (hereinafter abbreviated as "ABS"), which is mounted on four wheels of a vehicle to prevent the wheel from being locked during braking based on information collected through a wheel sensor that senses the speed of the wheel ), A pressure sensor for detecting the pressure of the master cylinder so as to control the braking force to each wheel by using the pressure of the master cylinder mounted on the engine, a pressure sensor mounted on the steering wheel and determining the steering effort based on the angular velocity of the steering wheel A steering wheel angular velocity sensor, etc., which can be included in the traveling safety device.

In addition to the driving safety device, there may be various devices that can automatically control the vehicle according to the weather conditions. For example, the device may be installed in a windshield class, Rain sensor for detecting information and operating the wiper of the vehicle, wiper operation sensor for detecting the operation of the wiper, and outdoor temperature sensor for automatically operating the air conditioner by measuring the outside temperature of the vehicle .

In this way, the road information collecting apparatus 10 collects road surface information using various devices provided in the vehicle, that is, a driving safety apparatus, and devices capable of automatically controlling the vehicle according to the weather conditions.

In other words, when the ABS is operated while the vehicle is running, it can be judged that the current road surface is slippery. In addition, when the outdoor air temperature detected through the outdoor temperature sensor is below zero, the present road surface can be judged to be in a slippery freezing state. Further, when the wiper is actively operating through the wiper operation sensor, it can be determined that the amount of rain is lowered.

Thus, the road surface information is collected by using various devices provided in the vehicle, or information detected through the device.

Then, the road information collecting apparatus 10 confirms the vehicle position information at the time when road road surface information is collected together with the collected road surface information, and then transmits the road surface information and the vehicle position information to the travel information providing apparatus 30 do.

Here, the road surface information may be collected in real time and transmitted to the driving information providing device 30, but when the various devices provided in the vehicle start to operate, the road surface information is transmitted to the driving information providing device 30 Alternatively, the road surface information may be collected for a predetermined period or a predetermined interval and then transmitted to the travel information providing apparatus 30. [

More specifically, when the destination information is input from the user, the user terminal device 20 confirms the current user location information, and transmits the destination information to the destination Information and user location information to the travel information providing device 30 and displays the travel route on the pre-stored map data when the travel route and the arrival scheduled time are received from the travel information providing device 30, Means a device capable of outputting.

Such a user terminal 20 may be implemented in various forms such as a navigation device, a smart phone, a tablet PC, a PDA (personal digital assistant), a portable multimedia player (PMP) And the like. Any device can be applied to the user terminal 20 of the present invention as long as it can display the traveling route to the user through the map data.

Although the road information collecting apparatus 10 and the user terminal apparatus 20 are illustrated as independent apparatuses in an embodiment of the present invention, the present invention is not limited thereto, The terminal device 20 may be implemented as a single device.

Preferably, the road information collecting apparatus 10 and the user terminal apparatus 20 may be devices located in the vehicle.

That is, since it is necessary to collect current road surface information while driving the vehicle and to guide a traveling route suitable for the user when driving the vehicle, it is preferable that the device is present in the vehicle 50 as shown in FIG. 1 , But is not limited thereto.

The running information providing apparatus 30 is a device capable of providing various information related to running information to a vehicle for smooth running of the vehicle. In particular, the running information providing apparatus 30 of the present invention is a device When the information is received, the estimated arrival time corresponding to the traveling route and the traveling route to the destination is calculated and transmitted to the user terminal 20. [

Thereafter, when road surface information and vehicle position information are received from at least one road information collecting device 10, the risk level is determined based on the road surface information, and a user who is likely to pass through the area corresponding to the vehicle position information After the terminal device 20 is extracted, the estimated arrival time previously transmitted to the extracted user terminal device 20 based on the risk level is adjusted and retransmitted.

C & When the vehicle location information (for example, area B) is received, the risk condition information preset in the area corresponding to the vehicle location information is confirmed.

Here, the risk condition information is a measure that can be used to determine how much difference there is in comparison with the state of the original road surface. For example, the road condition information may include a predetermined threshold value or road surface information And may be condition information on the number of the information collecting apparatuses 10.

For example, if the preset risk condition information in area B is set to "dangerous" when "ABS operation oil, wiper operating state strong, ambient temperature is below zero" or "ABS operation possible" The above road surface information is in a state corresponding to a risk.

That is, since the ABS is currently operating in the B zone, the road information providing apparatus 30 is currently in a slippery state on the road surface, and the wiper is operating strongly, so that a large amount of rain or snow is falling, -5 ° C, it is judged that the road is in a state of being frozen and in a state corresponding to the degree of risk that requires a great deal of attention in running the vehicle.

Therefore, since the road surface of the current area B is in a dangerous state, the travel information providing device 30 transmits the travel route information previously transmitted to the user terminal device 20, And extracts the user terminal 20 which is highly likely to pass through the area B.

Thereafter, when the user terminal device 20 of the first vehicle 50a is extracted as having a high possibility of passing through the area B, the estimated arrival time information previously transmitted to the user terminal device 20 of the first vehicle 50a is The time required to pass through the area B is adjusted according to the risk, and the time is again transmitted to the user terminal device 20 of the first vehicle 50a.

On the other hand, when the risk condition information is condition information on the number of the road information collecting apparatuses 10 providing road surface information, the road information collecting apparatus 10 that simultaneously provides the road surface information on the B area includes 10 or more If it is between 5 and 10, it can be judged to be "at risk."

First, when the service control unit 33 receives the destination information (for example, the B / B building) and the user location information (for example, the guide A building) from the user terminal 20 of the first vehicle 50a, Searches for the travel route from "Guro A building" to "Song B building B".

Here, the traveling route searching method can search the traveling route by taking various information such as the information about the traffic congestion state and the weather information into consideration while searching the traveling route, but it is a known technique, so a detailed description will be omitted.

Thereafter, when a traveling route passing through areas A, B and C from "Gurogu A building" to "Songpa B building" is set, the service control part 33 calculates a scheduled arrival time corresponding to the traveling route, And the estimated arrival time to the user terminal 20 of the first vehicle 50a that has transmitted the destination information and the user location information.

Thereafter, the service control unit 33 receives three kinds of road surface information of "ABS operating oil, strong wiper operating state, ambient temperature -5 deg. C" from the road information collecting apparatus 10 of the second vehicle 50b, When the vehicle location information (for example, area B) at the time when the road surface information is collected is received, the risk level is determined based on the received road surface information.

Here, the risk level is determined by comparing with the predetermined risk condition information, and the predetermined risk condition information can be set as shown in Table 1 below.

area ABS Information About wiper operation Ambient temperature Risk Area B U River Zero Prize U - - medium radish medium video Ha

The risk condition information shown in Table 1 is set as risk condition information corresponding to region B and the received road surface information is compared with the risk condition information as a result of " Since the road surface condition of the area B is in a "risky" state requiring a driver's deep attention, the service control unit 33 can notify the driver of the vehicle The vehicle that is likely to pass through the area is extracted.

Here, a vehicle driver who is likely to pass through the area (area B) can confirm based on the traveling route that has been transmitted to the user terminal 20 of the vehicle.

In the above example, since the traveling route previously transmitted to the user terminal device 20 of the first vehicle 50a passes through areas A, B, and C, the service control section 33 sets the first vehicle 50a to B It is extracted to the driver of the vehicle who is likely to pass through the area, and the expected arrival time of the vehicle, which corresponds to the traveling route, is confirmed by the user terminal device 20 of the first vehicle 50a.

Thereafter, the service control unit 33 confirms the predetermined safe running speed in response to the risk in order to adjust the estimated arrival time in accordance with the risk. For example, if the recommended safe operating speed in region B is 60 km, the safe running speed in the "at risk" state can be 30 km.

Thereafter, the estimated arrival time can be adjusted differently based on the confirmed safe running speed.

In addition, in the embodiment of the present invention, the risk condition information is determined by comparing with the predetermined threshold value for each road surface information, but the present invention is not limited thereto and can be set from various viewpoints.

For example, when the road surface information is received from the road information collecting apparatus 10 of a plurality of vehicles simultaneously operating in the area B, the road surface information is received from one road information collecting apparatus 10, It may be judged to be higher.

When the number of the road information collecting apparatuses 10 providing the road surface information after a certain period of time decreases, the risk may be lowered step by step in the case of determining the risk according to the number of the road information collecting apparatuses 10.

To this end, the service control unit 33 of the present invention includes a risk determination module 33a for determining a risk level by comparing with predetermined risk condition information, a travel guidance module for searching and setting a travel route, 33b.

As described above, the travel information providing apparatus 30 according to the embodiment of the present invention can provide a more accurate arrival scheduled time to the vehicle driver based on the road surface information collected from a plurality of other vehicles, It is possible to more accurately measure the current road surface state during driving through the device.

The traveling information providing apparatus 30 of the present invention may be implemented as one or more servers operating in a server-based computing mode or a cloud mode. In particular, the information transmitted and received through the travel guide system 100 may be provided through a cloud computing function that can be permanently stored in the cloud computing device on the Internet. Here, cloud computing utilizes Internet technology in digital terminals such as desktops, tablet computers, laptops, netbooks and smart phones to provide virtualized IT (Information Technology) resources such as hardware (server, storage, (Database, security, web server, etc.), service, data, etc. on demand. In the present invention, all information transmitted and received between the road information collecting device 10, the user terminal device 20, and the travel information providing device 30 is stored in the cloud computing device on the Internet and can be transmitted anytime and anywhere .

5 is a schematic flowchart for explaining a driving guidance method in the driving information providing apparatus according to the embodiment of the present invention.

Referring to FIGS. 1 and 5, first, the travel information providing apparatus 30 receives user location information and destination information from the user terminal 20 of the first vehicle 50a in step S101. Then, the travel information providing device 30 searches for the travel route to the destination based on the user location information. It is possible to search by taking into account traffic congestion situation information for each road when searching for a traveling route. Thereafter, when the travel route is set, the travel information providing device 30 calculates the estimated arrival time corresponding to the set travel route (S105).

Then, the travel information providing device 30 transmits the travel route and the estimated arrival time to the user terminal 20 of the first vehicle 50a in step S107.

Thereafter, the travel information providing device 30 determines whether the road surface condition is different from the normal road surface on the basis of the road surface information received through the road information collection device 10 of the second vehicle 50b, In the case of a different state than normal, it is also possible to retransmit by adjusting the estimated arrival time previously transmitted to the first vehicle 50a.

This will be described with reference to Figs. 6 and 7. Fig.

6 is a schematic flowchart for explaining a road surface information collecting method in a road information collecting apparatus according to an embodiment of the present invention.

Referring to FIGS. 1 and 6, the road information collecting apparatus 10 collects road surface information from various devices provided in the vehicle in step S201.

Here, the road surface information can be collected through the running stabilizing device for stable vehicle driving and the device capable of automatically controlling the vehicle according to the weather conditions.

For example, information on the ABS operation is collected through an ABS device that prevents the wheel from being locked during braking based on information collected through a wheel sensor, pressure information detected through a pressure sensor provided in the master cylinder is collected, The measured information from the running stabilizer for stable driving of the vehicle such as the angular velocity information detected by the steering wheel angular velocity sensor mounted on the steering wheel can be collected and used as road surface information.

In addition, it is also possible to collect rain amount information detected through a rain sensor mounted on a windshield, to collect information on wiper operation detected through a wiper operation sensor, The information measured from a device that can automatically perform various controls on the vehicle according to a weather condition can be used as road surface information.

Thereafter, the road information collecting apparatus 10 transmits the road surface information collected at step S203 and the vehicle position information at the collected time to the travel information providing apparatus 30.

Hereinafter, a method of calculating the estimated arrival time in the travel information providing device 30 will be described in more detail.

FIG. 7 is a specific flowchart for explaining a scheduled arrival time calculation method for traveling guidance according to an embodiment of the present invention.

1 and 7, the travel information providing apparatus 30 receives road surface information and vehicle location information collected from the road information collecting apparatus 10 in step S301.

Then, based on the received road surface information, the risk level is determined (S303) to determine whether the road surface condition of the corresponding area is different from the normal road surface condition.

The risk can be judged from various viewpoints. For example, according to the number of the road information collecting apparatuses 10 that judge the risk by comparing with a predetermined threshold value for each road surface information, Can be determined.

As a result of the risk assessment, the current road surface condition of the corresponding area can be used to provide information on the road surface condition, such as "dangerous" or "dangerous" It is possible to extract and provide the vehicle driver who is expected to pass through the area.

At this time, it is also possible to check the safe running speed according to the road surface condition and transmit the same together.

That is, the predetermined safe running speed is confirmed in response to the risk (S305), the user terminal device 10 likely to pass through the area corresponding to the vehicle location information is extracted (S307), and the extracted user terminal device 10 to the user terminal 10 (S309), based on the safe traveling speed (S309).

As described above, according to the driving guidance method according to the embodiment of the present invention, when the road surface condition differs from the normal road surface on the basis of the information collected through the road information collection device 10, It is possible to calculate the expected arrival time.

Hereinafter, a driving guidance method according to an embodiment of the present invention will be described in detail with reference to FIG.

In step S403, the travel information providing device 30 sets the travel route to the destination based on the user location information. Then, the travel information providing device 30 calculates the estimated arrival time corresponding to the travel route in step S405, and then transmits the travel route and the estimated arrival time to the first vehicle 10a (S409).

Thereafter, the driving route and the estimated arrival time information are outputted through the user terminal device 20 of the first vehicle 50a (S409) and provided to the user, and the user can perform the vehicle operation based on this.

The second vehicle 50b, which is driving the road on the traveling path of the first vehicle 50a, collects road surface information during vehicle operation through various devices provided in the vehicle in step S411.

The second vehicle 50b transmits the road surface information collected in step S413 to the travel information providing device 30 together with the vehicle location information of the second vehicle 50b.

Here, the road surface information may be transmitted for a predetermined period of time, or may be transmitted to the travel information providing apparatus 30 only when the road surface information is collected for the first time.

The travel information providing device 30 receives the information and determines the risk level based on the road surface information in step S415.

Here, the risk may be determined by comparing with a predetermined threshold value for road surface information, or may be determined according to the number of road information collecting apparatuses 10 providing road surface information.

Thereafter, if it is determined that the road surface condition is different from the normal condition, the driving information providing device 30 extracts a vehicle, for example, the first vehicle 50a likely to pass through the area in step S417.

In order to adjust the estimated arrival time previously transmitted to the first vehicle 50a in step S419, the travel information providing device 30 confirms the predetermined safe travel speed in response to the risk, After adjusting the time (S421), the adjusted arrival scheduled time is transmitted to the first vehicle 50a (S423).
