Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering notification method and apparatus,

[0001] The present invention relates to a steering notification method and apparatus thereof for an emergency in a vehicle condition, and it can inform the steering direction through a vehicle internal system when an emergency occurs, or inform the outside or another vehicle The present invention relates to a steering notification method and an apparatus therefor in a vehicle emergency situation.

As the spread of automobiles increases, automobiles are becoming a necessity for modern people, and the demand for convenient car service related to vehicle management and maintenance is increasing.

On the other hand, as the technology of automobiles develops, the control of the important parts of the present automobiles is mostly performed by electronic control. Therefore, devices capable of acquiring information of various vehicles as well as electronic control from such devices and providing various services to the driver have been developed and commercialized and used.

In recent years, techniques for communicating information using automobiles based on a wireless communication and a position information system (GPS) using a satellite have been applied as telematics.

Telematics is a combination of telecommunication and informatics. It combines a GPS (Global Positioning System) and a GIS (Geographical Information System) with a car. It is a comprehensive information system that guides the driver through the terminal and informs traffic information in real time. On the other hand, telematics is also called automotive telematics in that it uses an auto PC that can exchange e-mails in the car and retrieve various information through the Internet. The driver can remotely diagnose the vehicle through the wireless network, and can use various information such as traffic, life information, emergency rescue, etc. with the auto PC equipped with the wireless modem, and can transmit the telephone message to the office and friends, (e-mail), or download an audio book (audio-book).

In general, telematics can be classified into three types of services: traffic information and navigation system services, vehicle maintenance services such as safe driving, vehicle protection and fault diagnosis, and entertainment and communication services for users, To this end, GPS (Global Positioning System) technology, Geo-graphic Information System (GIS) and Intelligent Transport Systems (ITS) Can be provided.

On the other hand, even if the vehicle is equipped with such a tallematics system, the accident can not be completely prevented. Especially, in case of emergency, accidents caused by incorrect steering of the driver occupy a large part in all accidents.

On the other hand, a method of controlling the output ratio for steering stability of the emergency brake by means of the telematics system has been proposed, but it has not brought about a substantial effect.

The current steering power control method for steering safety has a weak aspect in coping with sudden braking accidents. Especially, the risk of damage to the collision object or the passenger on board is remained because it depends on the operation of the driver without consideration of human injury.

In order to solve this problem, techniques for improving the safety of the vehicle and the passengers have been continuously developed. In recent years, not only the safety of vehicles but also the technology for minimizing the damage of objects and persons around them has become a trend.

However, although ABS systems for steering assist have been developed to prevent vehicle slippage or accidents at the time of the current rapid braking, there is a need to rely on driver operation after the emergency brakes at present and to reduce the damage No attempt is made.

In order to solve the above-mentioned problems, the present invention provides a steering direction according to a state of a vehicle interior and exterior based on various sensors and vehicle control technologies currently developed, thereby minimizing loss of life and property damage, Can provide a new function.

It is another object of the present invention to provide a system technique capable of informing a desired steering direction at the time of emergency braking or accident prediction, or automatically informing a steering direction to the outside.

According to another aspect of the present invention, there is provided a method of notifying an emergency situation of a vehicle, comprising: sensing a state of the vehicle using at least one sensor; Determining whether the vehicle is in an emergency state based on the sensed state of the vehicle; Determining a steering path if it is determined that the vehicle is in the emergency state; And performing steering direction announcement based on the determined steering path.

According to another aspect of the present invention, there is provided an emergency notification apparatus for a vehicle, comprising: at least one sensor unit for sensing a state of the vehicle; An emergency situation determiner for determining whether the vehicle is in an emergency state based on the sensed state of the vehicle; A steering path determining unit that determines a steering path when it is determined that the emergency is present; And a controller for controlling the steering direction notification based on the determined steering path.

According to the embodiment of the present invention, the steering direction of the vehicle can be informed by interlocking with the vehicle internal system and the external system according to the present invention.

As a result, it is possible to minimize damage to persons and damage to property, and to improve vehicle safety.

The notification device 100 may operate in association with a web storage that performs a storage function of the storage unit on the Internet.

The control unit 110 typically controls the overall operation of the notification device 100. For example, emergency situation determination, steering path determination, steering direction notification method determination, and related control and processing are performed.

The control unit 110 may acquire state information of the vehicle sensed by at least one sensor included in the sensor unit 130 and may determine whether the vehicle is in an emergency based on the sensed state information of the vehicle.

If it is determined that the vehicle is in an emergency, the control unit 110 may determine the steering path and perform the steering direction notification based on the determined steering path.

The electric-field control unit (ECU) 150 may control the overall length of the vehicle according to the steering notification signal of the control unit 110 to perform the steering notification. For example, the control unit 110 can perform a steering notification by controlling the headlights of the vehicle's front and rear lights or the output of the HUD system according to the steering notification signal.

Meanwhile, the controller 110 may be connected to a plurality of modules for determining an emergency situation and determining a steering path. The emergency determination unit 140 may determine whether the vehicle is in an emergency based on the sensed data from the sensor unit 130 and transmit the result to the control unit 110. The damage analysis unit 160 analyzes the vehicle And outputs the collision expected damage degree for each route based on the state information to the control unit 110.

1, the control unit 110 is shown as a separate module from the emergency determining unit 140 and the damage analyzing unit 140. However, the present invention is not limited to this, The control unit 140 and the damage analysis unit 140. The operation of the control unit 110 will be described below in more detail.

For example, the control unit 110 may output a degree of damage according to the path based on the sensed state of the vehicle, and may determine a path that minimizes the degree of damage to be the steering path.

Also, the controller 110 may select the steering direction notification method, and may perform the steering notification corresponding to the steering path through the output unit 170 according to the selected steering direction notification method. The steering direction notification method may include at least one of an internal notification or an external notification.

In particular, when the steering direction notification method is an external notification, the control unit 110 may transmit a steering notification signal to the ECU 150 to control at least one of the headlights corresponding to the steering path or the rear light.

On the other hand, the control unit 110 may determine whether or not to determine an emergency situation based on the brake pressure, and may determine an emergency situation based on the surrounding object or vehicle information acquired through the sensor unit 130. [

FIG. 2 is a flowchart illustrating an operation method of the notification device 100 according to an embodiment of the present invention.

First, the vehicle where the notification device 100 is located starts operating (S100).

Thereafter, the control unit 110 determines whether it is an emergency situation (S110).

The control unit 110 may transmit the sensing data to the emergency situation determination unit 140 and determine whether the emergency situation is based on the emergency state information received from the emergency state determination unit 140. [

Here, the emergency determining unit 140 may determine the urgency by recognizing the pressure and time of the brake from the sensing data. In addition, the emergency determining unit 140 can determine the emergency situation by determining the motion of a nearby object or vehicle from the sensing data, and calculating the possibility of collision with the vehicle including the notifying device 100. [

Further, the control unit 110 can receive the motion information of the surrounding vehicle through the communication unit 120 using the inter-vehicle communication, and the emergency situation determination unit 140 calculates the possibility of collision according to the motion information of the vehicle around the vehicle , And can determine whether or not it is an emergency situation.

If it is determined that the vehicle is in an emergency, the control unit 110 determines a steering path (S120). In order to determine the steering path, the control unit 110 may use the damage analysis unit 160. The damage analysis unit 160 may output the degree of damage according to the path based on the sensing data, and the control unit 110 may determine the path having the minimum degree of damage for each path as the steering path.

Here, the degree of damage may include personal injury or material damage. The degree of personal damage can be calculated based on the internal sensing data as the degree of damage to the passengers in collision and the degree of physical damage can be calculated on the basis of the external sensing data to the degree of damage to the external object or the vehicle at the time of the collision.

In addition, the human damage degree can be calculated by the external sensing data when the collision object is discriminated as a person.

The physical damage degree can be calculated in proportion to the impact amount, and the personal injury degree can be calculated by multiplying the physical damage degree by a predetermined weight value.

The control unit 110 may include a separate module for route determination. The control unit 110 may include a path determination unit.

The path determining unit may determine the steering path that minimizes the degree of damage using the internal and external sensing data received from the sensor unit 130. [

In addition, the path determining unit may determine a path through which the collision damage is minimized as a steering path by predicting the traveling path of the external object.

Then, the controller 110 performs the steering notification according to the determined steering path (S130).

The control unit 110 generates a steering notification signal and transmits the steering notification signal to the ECU 150 to control the steering notification to be performed. Also, the controller 110 may generate a steering notification signal and transmit the steering notification signal to the output unit 170 to control the steering notification to be performed. The control unit 110 determines which electric or power output unit is to be controlled according to the steering notification method, and can transmit the corresponding control signal.

3 is a flowchart illustrating an operation method of a notification device according to another embodiment of the present invention.

Referring to FIG. 3, when a steering path is determined in the path determination unit of the control unit 110 (S200), the control unit 110 selects a notification method (S210).

The control unit 110 can select a notification method according to a preset notification method according to user input. In addition, the notification method may include an internal notification or an external notification.

Then, the controller 110 can perform the steering direction notification according to the selected notification method (S220). The control unit 110 may determine a target total output unit or target output unit to which the steering direction notification signal is to be transmitted according to the selected notification method, and may transmit the steering direction notification signal to the determined total or target output unit.

4 is a view for explaining internal notification methods according to an embodiment of the present invention.

According to the embodiment of the present invention, the control unit 110 performs the steering direction notification using the HUD of the vehicle. For example, the control unit 110 may convert the determined damage minimization steering path into image data that can be displayed on the HUD, and transmit the converted image data to the front HUD through the ECU 150 to be displayed on the HUD.

Also, the controller 110 may control the display unit included in the output unit 170 to display the steering direction notification.

Meanwhile, as shown in FIG. 4, the display HUD direction indication indicator e may be displayed in the HUD. This can be a general direction indicator by the navigation operation of the vehicle.

However, there is a need to distinguish between the direction indication of the navigation route navigation using the HUD and the steering direction notification according to the emergency situation judgment. Accordingly, the control unit 110 can distinguish the navigation direction indicator e and the steering direction notification a, b, c, and d from the HUD.

The distinction method of the steering direction notification may be color, size, shape, flashing, or visual effect. For example, the control unit 110 can be controlled so that the steering direction announcement (a, b, c, or d) is displayed in the state that the navigation direction indication e is displayed on the HUD. Also, for example, the control unit 110 may be controlled so that the steering direction notice (a, b, c, or d) is displayed after changing the navigation direction indication e to be not displayed in the HUD.

As shown in FIG. 4, there are (a) a fixed arrow display system, (b) an arrow flashing system, (c) a progressive arrow display system, or (d) Method, and the like.

Meanwhile, according to the embodiment of the present invention, in the case of the internal notification, the steering direction can be informed by using the motion of the steering apparatus in the internal electric field. For example, the control unit 110 may determine the current preferred steering direction and steering angle according to the determined damage minimization steering path, and may control the rotational resistance value or the feedback value of the steering wheel corresponding to the steering direction and the steering angle.

In addition, according to another embodiment of the present invention, the controller 110 can move the steering device in the steering direction by a predetermined small value in the case of the internal notification. In this case, there is no effect on the control of the vehicle, but there is an effect that the user can instantly notify the user of the desired steering direction.

According to the embodiment of the present invention, in the case of the internal notification, the control unit 110 can notify the steering direction of the steering wheel using the magnitude of the vibration attached to the steering wheel. In this case, when rotating in a specific direction, there is an effect of guiding the driver to steer in a direction in which vibration does not occur by generating vibration.

Meanwhile, according to the embodiment of the present invention, the control unit 110 may inform the steering direction through the output unit 170 by voice.

According to the embodiment of the present invention, in the case of the internal notification, the control unit 110 may automatically inform the steering direction by controlling the warning light inside the vehicle. At this time, the color of the warning light indicating the steering direction can be controlled differently from that of the conventional warning light color.

5 is a flowchart illustrating an operation method of a notification device according to another embodiment of the present invention.

Referring to FIG. 5, first, the controller 110 determines a steering path (S400), and selects a notification method according to the determined steering path (S410).

Then, the controller 110 determines whether the external notification is performed according to the selected notification method (S420).

If an internal notification other than the external notification is selected, the controller 110 transmits the steering direction notification signal to the internal electric field to control the internal notification as described above (S440).

If the external notification is selected, the controller 110 transmits the steering direction notification signal to an external field located outside the vehicle, and controls external notification to be described later (S430). The external notification can be performed by controlling the lighting of the headlamp, the side mirror or the tail lamp according to the direction.

6 to 8 are diagrams for explaining external notification methods according to an embodiment of the present invention.

As shown in FIG. 6, when the steering direction is determined, the control unit 110 may transmit a control signal for controlling the rear indicator light (or tail lamp) corresponding to the determined steering direction to the ECU 150. As a result, the vehicle can inform the external vehicle of the steering direction in accordance with the backward indicator light.

In particular, according to the embodiment of the present invention, the direction indication using the tail lamp and the steering direction notification according to the emergency situation judgment can be distinguished from each other. As shown in FIG. 6, the distinguishing method may include color, size, shape, lighting time, flicker timing, etc., and may be lit separately from the existing taillight direction display.

In addition, when the steering direction is determined, the controller 110 controls the color of the rear indicator light corresponding to the determined steering direction to inform that the vehicle is in emergency. For example, by controlling the color of the rear indicator light with the red flickering signal, not only the emergency situation is noticed but also the steering direction can be informed to the external vehicle together.

7, when the steering direction is determined, the controller 110 controls the lighting of the side mirrors corresponding to the determined steering direction to notify the emergency situation and notify the external vehicle of the steering direction.

The control unit 110 can distinguish between the direction display using the existing side mirror and the steering direction notification based on the determination of the emergency situation.

Particularly, according to the embodiment of the present invention, as shown in FIG. 7, the distinguishing method may include color, size, shape, lighting time, flicker timing, etc., .

8, when the steering direction is determined, the control unit 110 transmits a control signal for controlling the direction of the headlamp to the determined steering direction to the ECU 150 to notify the emergency situation, Direction can be easily grasped by the opposite driver, and at the same time can be informed to the external vehicle.

The method according to the present invention may be implemented as a program for execution on a computer and stored in a computer-readable recording medium. Examples of the computer-readable recording medium include a ROM, a RAM, a CD- , A floppy disk, an optical data storage device, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet).

The computer readable recording medium may be distributed over a networked computer system so that computer readable code can be stored and executed in a distributed manner. And, functional programs, codes and code segments for implementing the above method can be easily inferred by programmers of the technical field to which the present invention belongs.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
