CAR NAVIGATION SYSTEM, STEERING WHEEL AND COVER FOR CAR NAVIGATION, CAR COMPRISING THE SAME, AND METHOD FOR GUIDING DRIVING DIRECTIONS USING THE SAME }

The present invention relates to a car navigation system, a steering wheel and a cover for a car navigation system, a car including the same, and a car driving guide method using the same. More specifically, the information about a car driving direction is provided using a tactile signal of a driver. The present invention relates to a car navigation system, a steering wheel and a cover for car navigation, a car including the same, and a vehicle driving guidance method using the same.

In general, a navigation system of a vehicle receives a radio wave containing information through a GPS device using three or more satellites to determine the current position and current speed of the vehicle, and maps the current position of the vehicle to a mass information storage medium. After reading the display on the display unit, the driver can know the current position, speed, driving direction and road information of the vehicle through the screen displayed on the display unit.

1 shows an interior view of a car using a conventional navigation system. The conventional car navigation system uses a visual method through the display unit screen 20 or an auditory method using a speaker as a means for transmitting such information to the driver. However, when the information is displayed on the display unit and guided by using a visual method, the user holds the steering wheel 10 of the car for driving and continues to obtain the information provided by the navigation system. 20) It should be watched. As a result, the driver may not be able to look forward, and there is a risk that the concentration of attention to the forward look increases the risk of an accident. In addition, in the method of guiding the voice information by using an acoustic means such as a speaker to guide the information, the voice information is not clearly transmitted due to music, broadcast, or conversation that the driver hears while driving. The voice information has a disadvantage in that the driver cannot concentrate on music or conversation. Therefore, the conventional navigation system uses only visual or auditory means for information on the direction of travel of the vehicle, and when the driver pays attention to this, there is a problem in that the concentration of the driver's front is lowered. In addition, in the case of the information transmission method using voice, the information is transmitted to non-drivers who do not need the steering information, which interferes with conversation or sleep. Therefore, navigation and driver's 1: 1 information transfer method are required rather than voice transmission method.

The present invention has been proposed in view of the above-described problems of the prior art, and an object of the present invention is to provide a navigation system for changing a navigation direction information into a tactile signal and transmitting the same to a driver.

In one embodiment of the present invention, the plurality of vibration units are spaced apart at intervals provided with three or more within the driver hand width range, and the control unit is located at the driver hand position sensed by the sensor unit to guide the right turn or the left turn. Corresponding plurality of vibration units vibrate sequentially in a clockwise or counterclockwise direction, respectively. In this case, the controller does not vibrate the vibration motor that does not correspond to the sensed driver hand position.

In another embodiment of the present invention, the control unit vibrates a plurality of vibration unit corresponding to the sensed driver hand position in a zigzag manner to guide the U-turn rotation, the strength of vibration as the distance of the rotation point is closer Can be increased gradually.

In addition, the control unit may vibrate the plurality of vibration motors simultaneously at a predetermined time interval when the specified speed of the road on which the vehicle is driven, the sensing unit may be provided in the vibration unit, The vibration unit may be a vibration motor.

The present invention also provides a steering wheel cover for a vehicle navigation system in which a plurality of vibration units are provided to vibrate the plurality of vibration units in response to vehicle driving information from the outside.

The present invention also comprises a plurality of vibration motors spaced at a predetermined interval; And a sensing unit for sensing the gripped driver hand position, wherein the driving information is guided by vibrating a vibration motor corresponding to the driver hand position sensed by the sensing unit. It provides a steering wheel, the vibration motor can be spaced apart at intervals provided with three or more within the width of the driver's hand.

In one embodiment of the present invention, when the traveling direction of the vehicle is a right turn or left turn, the plurality of vibration motors corresponding to the sensed driver hand position vibrate sequentially in a clockwise or counterclockwise direction, respectively, In the case of the U-turn rotation, a plurality of vibration motors corresponding to the sensed driver hand position may vibrate in a zigzag manner.

The present invention further provides a vehicle including the steering wheel for vehicle navigation.

The present invention provides a new vehicle driving guidance method to achieve the above object, the vehicle driving guidance method comprising the steps of receiving information from the outside of the vehicle driving direction; And transmitting tactile information corresponding to the received information to a driver by a vibrator provided in the steering wheel. In another embodiment of the present invention, the vehicle driving guide method is gripped by the steering wheel. The method may further include sensing a position of the driver's hand. Further, the driver transmission of the tactile information by the vibrator is performed by vibrating only the vibrator corresponding to the position of the driver's hand held by the steering wheel.

In another embodiment of the present invention, when the driving direction of the vehicle is a right turn or a left turn, a plurality of vibration motors corresponding to the sensed driver hand position vibrate sequentially in a clockwise or counterclockwise direction, respectively.

The present invention also comprises the steps of identifying the driving information including the current location of the vehicle based on the map data stored in the storage medium; And sequentially or simultaneously vibrating only the vibration unit corresponding to the position of the driver's hand holding the steering wheel, among the plurality of vibration units provided in the vehicle steering wheel, to guide the traveling direction of the vehicle from the driving information. When the driving direction of the vehicle is a right turn or a left turn, a plurality of vibration motors corresponding to the driver's hand position vibrate sequentially in a clockwise or counterclockwise direction, respectively.

In the vehicle navigation system and the steering wheel for navigation according to the present invention, the vibration order of the plurality of vibration motors is sequentially rotated in a specific direction so that information about the traveling direction is intuitively transmitted to the user through the user's hand holding the steering wheel. There is an advantage to be delivered. In addition, navigation information may be transmitted even when the user puts his hand on any position of the steering wheel by using a vibration unit formed of a plurality of motors, and navigation information may be transmitted to the driver even when the user puts one hand up. In addition, the use of the tactile signal to transmit navigation information has the effect of not disturbing the driver's eyesight or hearing and preventing the driver's forward attention. Eliminating the voice steering information that can be, and can deliver the actual necessary steering information only to the driver, there is an advantage that can reduce the disturbance caused by the voice not only the driver but also the passengers. Furthermore, since only the vibration motor in contact with the actual driver's hand is vibrated to transmit driving information to the driver, the driver can recognize very fast and immediate driving information, which is the same as or similar to the prior art based on visual information. The level of information transfer can be communicated to the driver.

Hereinafter, with reference to the accompanying drawings, it will be described in detail for the present invention.

2 is a front view of a steering wheel 100 (also referred to as a “handle” and herein referred to as a “steering wheel”) according to one embodiment of the invention. Referring to the drawings, the steering wheel 100 of the present invention is provided with a plurality of vibration motors (110, 120, 130, etc.) at regular intervals along the circumference. These vibration motors are electrically connected to the control unit, so that the control unit vibrates the vibration motors in a predetermined manner.

In one embodiment of the present invention, by using the steering wheel cover provided with the vibration motor, the vibration sensation to the driver. In this case, the effect of the present invention can be achieved simply by mounting the cover provided with the vibrator in the conventional vehicle, and the portability of the navigation system according to the present invention can be increased. However, not only a separate cover, but also a vibration motor may be provided on the steering wheel itself, in any case as long as the driver holding the steering wheel can receive the vibration sensation by the vibration motor all fall within the scope of the present invention.

In particular, the present invention focuses on the fact that when the plurality of vibration motors vibrate sequentially in one direction, the directionality is intuitively transmitted to the driver who holds the steering wheel, in particular, the steering wheel rotates 180 degrees than during normal driving. When the user rotates the vehicle rapidly, such steering wheel rotation occurs, or even when the steering wheel is gripped with only one hand, the directionality of the steering direction transmitted to the driver is constantly transmitted. I focused on the point. In addition, the vibration motor may be replaced with any kind of vibration unit as long as it can give the driver tactile information, which is within the scope of the present invention.

In the navigation system of the present invention, the vibration motor is vibrated in order to provide driving directions and dangerous information of the vehicle. That is, the controller of the navigation system transmits a vibration command to the vibration motor according to vehicle driving information such as left turn and right turn, and the vibration motor receives the electric signal to perform vibration.

Furthermore, the navigation system and the navigation steering wheel of the present invention include the sensing unit, which senses a driver's hand held by the steering wheel during driving. The sensing unit may be any type as long as it can accurately sense the gripped driver's hand position. In addition, in one embodiment of the present invention, the sensing unit is provided in the plurality of vibration motors, which is also just one embodiment of the present invention, and the present invention is not limited thereto.

According to the present invention, in particular, only the vibration motor contacted by the driver's hand is vibrated by the controller according to the driver's hand position information sensed by the sensing unit, thereby delivering very quick and immediate tactile information to the driver. That is, when vibrating all vibration motors provided in the steering wheel, inevitable delay of information transmission may occur, which in turn halves the effects of the present invention compared to the immediate transmission effect of the prior art by visual and audio information. Therefore, the present invention vibrates only the vibration motor corresponding to (ie, in contact with) the gripped driver's hand position in order to remedy this shortcoming, thereby achieving an immediate information transfer effect of visual and voice information levels.

Hereinafter, a driving information transmission method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing a steering wheel for a vehicle navigation and a driver's hand holding the same according to an embodiment of the present invention.

Referring to FIG. 3, the driver grips the vibration motors indicated by reference numerals 120, 130, and 140 among the vibration motors, and the vibration motors are spaced at predetermined intervals. In particular, in the present invention, the separation interval of the vibration motor is preferable if the driver's hand can contact at least three or more vibration motors, which is if the vibration motor is in contact with the driver's hand is less than three vibration direction of the driver This is because it is difficult to deliver immediately.

Hereinafter, a driver transmission method of steering information according to a vehicle navigation system and a steering wheel for navigation according to the present invention will be described in detail.

4 is a view illustrating a steering wheel when guiding a right turn signal or a left turn signal to a driver.

Referring to FIG. 4, when guiding information of a right turn, the controller vibrates a plurality of vibration motors provided around the steering wheel 100 at predetermined time intervals. That is, in order to allow the user to intuitively recognize the right turn signal, the vibration motor is sequentially vibrated in the clockwise direction (hereinafter referred to as 'first direction') from the driver's point of view of the driving direction of the vehicle. At this time, the initial market position of the vibration motor is preferably the first vibration motor 120 in the counterclockwise direction among the plurality of vibration motors in contact with the driver's hand, and then the sequential vibration proceeds clockwise. However, when the continuous time is progressed, since the tactile transmission is performed only by the traveling direction rather than the initial position of the vibration motor, the first vibration motor 120 in the counterclockwise direction does not necessarily have to be the initial position.

Specifically, the meaning of vibrating sequentially in the first direction, at a specific time (t), only the vibration motor 120 in contact with the sensed driver's hand performs the initial vibration and the remaining vibration motor does not vibrate. After a certain time, only another vibration motor 130 that is clockwise spaced at time t + 1 vibrates and the remaining vibration motor does not vibrate. In the same process, the vibration motor at time t + 2. Only 140 vibrates and the other vibration motor does not vibrate. Thereafter, the process is repeated, the vibration motor vibrates in the order of 120, 130, 140. However, the vibration motors 110 and 150 that do not come into contact with the driver's hand in the above process do not vibrate, thereby preventing unnecessary vibration motors that cannot directly give tactile information to the driver, thus providing immediate and quick tactile information. Can be given to the driver.

As such, when the plurality of vibration motors provided around the steering wheel 100 vibrate sequentially in the first direction, the driver holding the steering wheel by hand recognizes the right turn signal intuitively only through the touch of the hand. You can do it. Furthermore, the configuration of the present invention has the advantage that the direction of the steering direction can be intuitive to the user, regardless of the initial state of the steering wheel (for example, rotated 180 degrees) or the number of gripped driver hands. .

Similarly, in the left turn, the vibration of the sequential vibration motor proceeds counterclockwise from the driver's position among the vibration parts held by the driver. At this time, it is preferable that the first vibration motor 140 is a starting position in the clockwise direction, and then, the sequential vibration is repeated in the order of 140, 130, and 120.

As described above, the present invention can easily provide the rotation signal to the driver (see FIG. 7) not only to the driver who holds the steering wheel with both hands (see FIGS. 5 and 6) but also to the driver who holds only a specific part of the steering wheel using only one hand. Can be delivered immediately by the tactile information. To this end, it is preferable that the palm of the driver contacts three or more vibration motors, such as 'A' and 'B' of FIG. 5. The steering wheel for navigation of the above configuration vibrates only the vibration motor in contact with the driver's hand in sequence, thereby transmitting certain driving information to the driver regardless of the initial position of the steering wheel or the direction of the gripped hand.

In addition, in one embodiment of the present invention, the steering wheel according to the present invention can vibrate a plurality of vibration motors in contact with the driver's hand in various ways to guide the U-turn rotation in a predetermined manner, an embodiment of the present invention In the example, the U-turn rotation is guided by vibrating the plurality of vibration motors in a zigzag manner. That is, the zigzag method here means that each individual vibration unit vibrates at a predetermined time interval, but the direction thereof is changed sequentially. For example, referring to FIG. 3, first, the vibration unit 120 vibrates, and the vibration unit 130 and 140 next to each other vibrate, and then vibrates to 120 through 130 units from the vibration unit 140. This vibration will continue several times. In this case, the driver may receive tactile information distinguished from the one-way vibration. However, the above configuration is only one example of the present invention, it is possible to allow the user to recognize the U-turn information by various vibration configurations, which is within the scope of the present invention.

Furthermore, the present invention provides a method in which all vibration motors repeat vibration and non-vibration at regular time intervals to warn the driver when the speed of the vehicle exceeds the prescribed speed of the road or when the speed of the vehicle needs to be reduced due to the bumps. Provides a navigation system and method. In addition, the vibration motor of the steering wheel may be controlled so that the vibration intensity also increases gradually as the distance of the rotation point to start the left and right rotation or the U turn rotation is getting closer.

According to another embodiment of the present invention, there is provided a vehicle driving direction guidance method using the navigation system. This is as follows.

The present invention provides a vehicle driving guidance method comprising the steps of receiving vehicle driving information from the outside; And transmitting driving information corresponding to the received information to a driver by a vibrator provided in the steering wheel. That is, according to the present invention, after receiving driving information (for example, rotation information such as a right turn) from a navigation device provided in the vehicle, driving information corresponding thereto is generated by the vibration unit provided in the steering wheel. It is delivered to the driver by the tactile information. In this case, the tactile information may be transmitted to the driver by vibrating only the vibration motor contacting the driver's hand in the steering wheel as described above or sequentially. The vibration method of the vibration motor is as described above, and will be omitted below.

In addition, the present invention may determine the current position of the vehicle based on the map data stored in the storage medium, and then guide the driving direction by a method of sequentially moving the vibration portion of the steering wheel to guide the driving direction of the vehicle. There will be. At this time, the vibration portion of the steering wheel is limited to the range in direct contact with the driver's hand in the steering wheel, the vibration is performed by a plurality of vibration motor provided in the steering wheel. That is, only the vibration motor directly contacting the driver's hand among the plurality of vibration motors provided in the steering wheel is repeatedly vibrated in a predetermined direction, and the driver holding the steering wheel can be guided in the direction of movement by sensing the vibration. will be.
