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 a current position and a current speed of a 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 driving direction of the vehicle, and when the driver pays attention to this, there is a problem that the driver's concentration on 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 addition, the present invention provides a tactile signal for the driving direction of the vehicle through a steering wheel that is held by the driver to provide a steering wheel for steering, a wheel cover, and an automat including the steering information which can be directly transmitted only to the actual driver. For the purpose of

In addition, an object of the present invention is to provide a driving guidance method of a vehicle that can directly deliver the vehicle progress information to the actual driver.

The present invention for the above purpose, a plurality of vibration motor provided along the circumference of the steering wheel; And a controller for guiding vehicle progress information by controlling the vibration motor, wherein the controller provides a navigation system for a vehicle, wherein the plurality of vibration motors vibrate simultaneously or sequentially. In one embodiment of the present invention, the plurality of vibration units are provided in a handle cover mounted to the steering wheel, and the control unit vibrates the plurality of vibration motors sequentially in a first direction or turns left to guide a right turn. In order to guide the plurality of vibration motor may be sequentially vibrated in the second direction.

In an embodiment of the present invention, the control unit simultaneously vibrates two or more adjacent vibration motors of the vibration motors to guide the U-turn rotation, and the control unit gradually increases the intensity of the vibration as the distance of the rotation point approaches. Can be.

The controller may vibrate the plurality of vibration motors at predetermined intervals at a time when the specified speed of the road on which the vehicle is driven is exceeded.

The present invention is a steering wheel to achieve the above object; And a plurality of vibration motors spaced apart from each other at predetermined intervals on the steering wheel, wherein the plurality of vibration motors vibrate to guide the progress information of the vehicle. . The present invention also provides a steering wheel cover for a vehicle navigation system, characterized in that a plurality of vibration units are provided to vibrate the plurality of vibration units in response to vehicle driving information from the outside.

In this case, when the traveling direction of the vehicle is a right turn, the plurality of vibration motors may vibrate sequentially in the first direction, and when the traveling direction of the vehicle is a left turn, the plurality of vibration motors vibrate sequentially in the second direction. can do.

In addition, when the driving direction of the vehicle is a U-turn rotation, it is possible to simultaneously vibrate two or more adjacent vibration motors of the vibration motor.

Furthermore, the present invention includes a plurality of vibration motors around a steering wheel of a vehicle for guiding a vehicle driving direction, comprising: a first step of identifying a current position of a driving vehicle; A second step of recognizing information on a road corresponding to the current location; And a third step of guiding a driving direction of the vehicle based on the information of the road; wherein, in the third step, the plurality of vibration motors vibrate simultaneously or sequentially. to provide. In the third step, when the driving direction of the vehicle is a right turn, the plurality of vibration motors are vibrated in the first direction, and when the vehicle is turned left, the plurality of vibration motors are sequentially vibrated in the second direction.

Furthermore, the present invention comprises the steps of identifying the current position of the vehicle based on the map data stored in the storage medium; And vibrating the vibrating unit provided in the steering wheel sequentially or simultaneously to guide the driving direction of the vehicle. The vibrating unit may be a vibration motor.

In the exemplary embodiment of the present invention, when the traveling direction of the vehicle is a right turn, the plurality of vibration motors are rotated in a first direction, and when the traveling direction of the vehicle is a left turn, the plurality of vibration motors are sequentially rotated in a second direction. It can vibrate.

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.

Furthermore, the use of the tactile signal to transmit navigation information has the effect of not disturbing the driver's vision or hearing, and not disturbing the driver's forward attention, which is unnecessary for driving, and in severe cases, for driving. By eliminating voice steering information that may be disturbing and delivering only necessary steering information to the driver, there is an advantage of reducing the disturbance caused by the voice not only to the driver but also to the vehicle passenger.

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

2 to 3 are front views 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 is provided with the vibration motor, to deliver a vibration feeling 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.

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 holding the steering wheel, in particular, the steering wheel is rotated 180 degrees than during normal driving. State (i.e., when the user rotates the vehicle sharply, such steering wheel rotation occurs), or even when the steering wheel is gripped with only one hand, the direction of the steering direction transmitted to the driver is constantly transmitted. I was focused on. 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.

2 is a view of a steering wheel when guiding a right turn signal to a driver. In this case, when guiding information of a right turn, the controller vibrates a plurality of vibration motors provided around the steering wheel 100 in sequence. At this time, in order to make the user intuitively recognize the right turn signal, the vibration motor is vibrated sequentially in a clockwise direction (hereinafter referred to as 'first direction') from the driver's point of view of the vehicle's traveling direction. Specifically, the meaning of vibrating sequentially in the first direction, at any particular time (t), only the vibration motor 110 performs the vibration and the remaining vibration motor does not vibrate. After a certain time passes, only the vibration motor 120 vibrates at the time t + 1 and the remaining vibration motor does not vibrate. In the same process, only the vibration motor 130 vibrates at the time t + 2 and the other The vibration motor does not vibrate. The motor that performs the vibration moves sequentially in the clockwise direction, that is, the first direction.

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 may intuitively recognize the right turn signal only through the touch of the hand. It will be possible. 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 hands.

In addition, the vibration motor for starting the vibration of the plurality of vibration motor may be a motor provided at any position of the steering wheel. For example, in an embodiment of the present invention, if a vibration motor (110 in FIG. 2, hereinafter referred to as a 'starting vibration motor') located at the top of the steering wheel 100 from the driver's position starts vibration first, In the case of a right turn, the first motor 120 in the clockwise direction of the vibration motor vibrates at regular time intervals.

However, according to the present invention, if the vibration is rotated at least once regardless of the starting point, and the direction of the sequential vibration of the vibration motor is maintained, constant steering information is given to the driver regardless of the position of the user's hand and the steering wheel's position. I can deliver it. That is, in the present invention, since the steering direction is transmitted to the driver by the direction of the sequential vibration of the vibration motor, regardless of the position of the starting vibration motor and the like, the direction of the steering wheel and the gripped hand are not affected by the direction. It will be delivered.

Then, as shown in the arrow direction of Figure 2, it is preferable that the vibration motors located immediately next to the clockwise direction of the starting vibration motor 110 to vibrate sequentially. This is because not only the driver who holds the steering wheel with both hands but also the driver who holds only a certain part of the steering wheel using only one hand can easily transmit the right turn signal. Further, in the present invention, irrespective of the position of the starting vibration motor and the like, as long as the vibration motor vibrates sequentially with a constant directionality, the directionality of the sequential vibration of the vibration motor is determined by the initial position or direction of the steering wheel and the gripped hand. It can deliver a certain direction to the driver regardless of location.

3 is a view of a steering wheel when guiding a left turn signal to a driver. In this case, when guiding the information of the left turn, the control unit vibrates a plurality of vibration motors provided around the steering wheel 100 in sequence, and in this case, in order for the user to intuitively recognize that the left turn signal, the driving direction of the vehicle From the driver's point of view, the vibration motor vibrates sequentially in the counterclockwise direction (hereinafter referred to as 'second direction'). Specifically, the meaning of vibrating sequentially in the second direction, at any particular time (t), only the vibration motor 110 performs the vibration and the remaining vibration motor does not vibrate. After a certain time passes, at time t + 1, only another vibration motor positioned adjacent to the counterclockwise direction of the vibration motor 110 vibrates and the remaining vibration motor does not vibrate as shown in FIG. 3. do. In this manner, when the plurality of vibration motors provided around the steering wheel 100 vibrate sequentially in the second direction, the driver holding the steering wheel by hand may intuitively receive a left turn signal through the touch of the hand. It will be recognized.

The vibration motor for starting the vibration among the plurality of vibration motors may be any motor. In an embodiment of the present invention, if the driver sees a vibration motor (110 of FIG. 2, hereinafter referred to as a 'starting vibration motor') located at the top of the steering wheel 100 to start vibration first, in case of a left turn The vibration is made sequentially in the second direction. However, this is only one example of the present invention. If the vibration rotation having a constant direction is made more than once regardless of the starting point, steering information may be transmitted regardless of the position of the user's hand. That is, the position of the starting vibration motor shown in FIG. 3 is limited to one embodiment of the present invention, and the position of the starting vibration motor may be any position as long as the direction of the sequential vibration is the same, which is within the scope of the present invention.

3, the vibration motors located next to the counterclockwise direction of the starting vibration motor 110 may vibrate sequentially. As described above, the right turn signal can be easily transmitted not only to the driver who holds the steering wheel with both hands (see FIGS. 4 and 5) but also to the driver who holds only a specific part of the steering wheel using only one hand (see FIG. 6). In addition, the direction of the sequential vibration of the vibration motor may transmit a constant direction to the driver regardless of the steering wheel initial position and the direction of the gripped hand.

In addition, in one embodiment of the present invention, the steering wheel according to the present invention, two or more adjacent vibration motors of the plurality of vibration motors to vibrate at the same time to guide the U-turn rotation may move sequentially in the U-turn direction. In this case, by the simultaneous vibration of two or more vibration motors, the driver receives the progress information distinguished in terms of intensity from the left turn or right turn information by one sequential vibration of the vibration motor, and further, the two or more vibration motors. This gives the driver the direction of vibration, which allows the driver to recognize information in the U-turn direction, such as a right or left U-turn.

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.

In the case of guiding the navigation information using the steering wheel according to the present invention, the driving information may be guided even in various hand states of the driver. That is, even when the steering wheel is straightened as shown in FIG. 4 or the steering wheel is staggered as shown in FIG. 5, a plurality of vibration motors are always located in the palm of the user so that the driver can detect the sequential vibration of the vibration motor. It will be able to recognize the progress of the car. It is preferable to adjust the size of the vibration motor and the distance between the vibration motor and the vibration motor so that three or more vibration motors positioned at the part of the steering wheel gripped by the driver are always located (parts A and B of FIG. 4). Reference). This is because at least three vibration motors are preferably in contact with the driver's hand in order to recognize whether the driver vibrates sequentially in the first direction or sequentially in the second direction through the hand. .

In the steering wheel of the present invention, since the plurality of vibration motors vibrate sequentially or simultaneously, the driving information is provided to the driver through the tactile sense. As shown in FIG. 6, when the driver holds the steering wheel with one hand, It can be seen that the progress information regarding the driving of the car can be easily transmitted to the driver.

According to another embodiment of the present invention, there is provided a vehicle driving direction guidance method using the navigation system. Looking at this, the present invention is a method for guiding the vehicle driving direction with a plurality of vibration motors around the steering wheel of the vehicle, the first step to determine the current position of the driving car and the current position identified in the first step A second step of recognizing the information of the road corresponding to the based on the step and a third step of guiding the driving direction of the vehicle based on the information of the road in the second step. In the third step, the vibration of the steering wheel is transmitted to the driver's hand to guide the driving direction. For this purpose, the plurality of vibration motors provided in the steering wheel are vibrated simultaneously or sequentially. In this case, when the traveling direction of the vehicle is a right turn in the third step, the plurality of vibration motors are sequentially vibrated in the first direction, and when the traveling direction of the vehicle is left, the plurality of vibration motors are rotated in the second direction. It is preferable to vibrate sequentially.

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. In addition, the vibration portion of the steering wheel is provided by a plurality of vibration motors provided inside the steering wheel and vibrating them independently of each other. That is, the plurality of vibration motors provided in the steering wheel are sequentially vibrated in a predetermined direction along the circumference of the steering wheel, and the driver holding the steering wheel may be guided by the driving direction by detecting the vibration.
