JP 2000-221051

  In the conventional technology, no consideration is given to a case where a route for turning right or left at an intersection continuously for a short distance is set. In other words, in the conventional technology, it is guided after passing through the first intersection in the second and subsequent intersections among consecutive intersections, and thus driving operation for the second and subsequent intersections is performed. One cannot keep up with the heart in advance. Therefore, the driver must hesitate to perform the driving operation for the second intersection.

  The present invention has been made in view of the above problems, and provides a technique capable of guiding a driving operation to a driver in advance by a vibration mode of a vibrating body with respect to a curve continuously existing in front of the host vehicle. For the purpose.

  In order to achieve the above object, according to the present invention, information indicating N (N is an integer of 2 or more) curves continuously existing forward from the position of the host vehicle on the route is acquired, and the foremost is obtained. When the host vehicle reaches a predetermined position from the curve, the vibrating body provided at a position where the driver of the host vehicle can contact is vibrated in a vibration mode corresponding to the mode of the N curves. . According to this configuration, the driver can recognize that a plurality of curves are continuously present ahead of the host vehicle before reaching the plurality of curves. Further, the driver can associate a curve mode with the vibration mode. As a result, the driver can associate the driving operation performed when traveling along the curve from the aspect of the curve.

  The route information acquisition means only needs to be able to acquire information indicating the route of the host vehicle, and various configurations can be employed. The information indicating the route of the host vehicle may be information indicating a route with which the host vehicle is likely to travel, may be information indicating a recommended route obtained as a result of the route search, or manually by the driver. The information which shows the driving | running | working schedule path | route set by (1) may be sufficient, and the information which shows the presumed path | route obtained by a learning process from the past driving | running route may be sufficient. A road that the navigation device 10 determines to be a road may be handled as information indicating the route of the host vehicle.

  In the own vehicle position information acquisition means, various configurations for acquiring information indicating the position of the own vehicle can be employed. For example, using a signal from a GPS satellite, a signal from various sensors or cameras mounted on the vehicle, and map information, correction is made based on the locus on the map, and the position of the host vehicle is specified. You may acquire the position of the own vehicle by vehicle-to-vehicle communication or road-to-vehicle communication.

  The curve information acquisition means acquires information indicating N (N is an integer equal to or greater than 2) curves that are continuously present forward from the position of the host vehicle on the route. A curve refers to a point where the traveling direction of the road or the traveling direction of the host vehicle is not straight, such as a curve or corner along the road, or an intersection where a right turn or a left turn is set as a route. The N curves that exist continuously indicate N curves in which the distance between adjacent curves in the order of passage on the route is equal to or less than a predetermined distance. The distance between the curves may be derived from the end of the curve, the center of the curve, or the like, or may be derived from a reference position preset for each curve. The curve information acquisition means determines whether there are a plurality of curves that continue forward from the position of the host vehicle, the route acquired by the route information acquisition means, and the position of the host vehicle acquired by the host vehicle position information acquisition means. If it exists, information indicating the mode of the curve is obtained. The form of the curve includes the distance between each curve and the host vehicle, the number of continuous curves, the distance between each curve, the direction in which each curve bends, and the like. The degree of bending of each curve may be included.

  In the vibrating body control means, it is only necessary that the plurality of curve modes acquired by the curve information acquisition means are associated with the vibration modes of the vibrating body to vibrate the vibrating body. The vibrating body control means controls at least one vibrating body provided at a position where the driver of the host vehicle can come into contact. As for the vibration mode, it is only necessary that the curve mode can be generated intuitively or in a mode that can be associated with learning, and various vibration modes can be adopted.

  For example, the vibrating body control means generates a vibration corresponding to the Mth curve (M is an integer not less than 1 and not more than N-1) near the position of the host vehicle on the route before the vibration corresponding to the M + 1th curve. May be. That is, instead of simultaneously generating vibrations corresponding to the curves, the vibration generation time is shifted, and the vibrations corresponding to the curves existing in front are generated in order from the position of the host vehicle. According to this configuration, the driver is more intuitive that the curve corresponding to the M + 1th vibration is located behind the curve corresponding to the Mth vibration on the basis of the position of the vehicle. Can be associated with.

  In addition, the vibrator control unit increases the interval between the vibration corresponding to the Mth curve and the vibration corresponding to the M + 1th curve as the distance between the Mth curve and the M + 1th curve is longer. Also good. That is, the vibration generation interval is associated with the distance between successive curves. According to this configuration, the driver can intuitively associate the distance between the curves.

  Further, the vibrating body control means may generate the vibration corresponding to the Mth curve as a vibration stronger than the vibration corresponding to the M + 1th curve. That is, the vibration corresponding to the curve located closer to the own vehicle on the route is stronger and the vibration corresponding to the curve located farther is weaker. According to this configuration, the driver can intuitively associate that the curve corresponding to the strong vibration is closer to the host vehicle on the route than the curve corresponding to the weak vibration. Note that strong vibration refers to vibration with a high frequency or vibration with a large amplitude.

  Further, the vibrator control means may guide the Mth curve by generating a predetermined unit vibration M times. According to this configuration, the driver can easily associate that the M unit vibrations are vibrations corresponding to the Mth curve from the position of the host vehicle. Note that the unit vibration may be vibration within a predetermined unit time, and the mode of vibration is not limited. That is, a specific vibration may be generated within a specific period so that the number of times can be counted, and the vibration may be continuous or discrete.

  Furthermore, the vibration body control means may vibrate the vibration body provided on the right side for the driver when guiding a right turn with respect to the curve, and may vibrate the vibration body provided on the left side when guiding a left turn. According to this configuration, the driver intuitively associates a curve that turns to the right when it feels vibration of the vibrating body provided on the right side, and a curve that turns to the left when it feels vibration of the vibrating body provided on the left side. Can do.

  Furthermore, the vibrating body control means may select N vibrating bodies corresponding to the positions of the N curves with respect to the position of the host vehicle, and vibrate the selected vibrating bodies. For example, the vibration body provided closer to the driver's head in a state where the driver is seated in the driver's seat has a curve closer to the position of the own vehicle, and the vibration body provided closer to the driver's thigh front. You may make it match | combine the curve far from the position of the own vehicle. In this case, the driver can recognize that the vibration by the vibrating body close to the head corresponds to a curve close to the position of the host vehicle. As long as each position of the N curves with respect to the position of the host vehicle can be associated with each position of the vibrating body with respect to the reference position of the seat on which the driver is seated, the arrangement and quantity of the vibrating bodies, There is no particular limitation on how to associate with.

  Furthermore, as in the present invention, information indicating the mode of N curves (N is an integer of 2 or more) continuously present forward from the position of the host vehicle in the route is acquired, and a predetermined position is obtained from the foremost curve. A method of vibrating a vibrating body provided at a position where the driver of the host vehicle can come in contact with a mode of vibration corresponding to the mode of the N curves when the host vehicle arrives at It is also applicable. The navigation device, program, and method as described above may be realized as a single device, or may be realized using components shared with each part of the vehicle. Is included. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also established as a recording medium for a program for controlling the navigation device. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.

And a vibrating body controller 21d. In addition, the storage medium 30 stores map information 30 a for implementing a route guidance function by the navigation program 21. The map information 30a includes node data indicating nodes set on a road, link data indicating connection between nodes, data indicating a target, and the like, and is used for specifying the position of the own vehicle and guiding to a destination. Is done. The curve points, corner points, and intersection positions on the road are stored as node data.

  The route information acquisition unit 21a acquires a recommended route from the position of the host vehicle to the destination by searching based on the map information 30a and information indicating the position of the host vehicle (hereinafter referred to as host vehicle position information). This is a module that outputs as information indicating the route (hereinafter referred to as route information). The route information includes, for example, node data indicating nodes set at intersections on the route, and link data indicating connection between nodes. If no destination is set, a road determined to be a road may be treated as the route of the host vehicle.

  The own vehicle position information acquisition unit 21b is a module that specifies the own vehicle position information and outputs the own vehicle position information. The own vehicle position information acquisition unit 21b displays the position information acquired from the signal output from the GPS receiver 40, the signal output from the gyro sensor 41, and the signal output from the vehicle speed sensor 42 on the map using the map information 30a.

In this specification, a curve refers to a location where the traveling direction of the road or the traveling direction of the host vehicle is not straight, such as a curve or corner along a road, an intersection where a right turn or a left turn is set as a route, and the like. The N curves that exist continuously indicate N curves in which the distance between adjacent curves in the order of passage on the route is equal to or less than a predetermined distance.

As for the mode of vibration, it is only necessary that the driver can generate the vibration in a mode in which the driver can associate the mode of the curve intuitively or by learning.
The configuration of the navigation device 10 has been described above.

(2) Vibration body control processing:
Next, the vibrator control process executed by the navigation device 10 in the above configuration will be described. When the navigation program 21 is executed by the navigation device 10, the route information acquisition unit 21a, the vehicle position information acquisition unit 21b, the curve information acquisition unit 21c, and the vibrating body control unit 21d perform the process shown in FIG. This vibrating body control process is repeatedly executed every predetermined time. Before the vibration body control process is executed, the route information acquisition unit 21a acquires route information.

  First, the host vehicle position information acquisition unit 21b acquires host vehicle position information (step S100). Specifically, the position information acquired from the signal output from the GPS receiver 40, the signal output from the gyro sensor 41, and the signal output from the vehicle speed sensor 42 is used as the basis of a map locus using the map information 30a. To determine the position of the vehicle.

  Next, the route information acquisition unit 21a determines whether route guidance is being performed (step S105). In this embodiment, the destination is set by the user, and it is determined whether route guidance to the destination is being implemented. If route guidance is not being performed, the vibrator control process is terminated. Next, the curve information acquisition unit 21c determines whether a curve exists within X meters ahead of the host vehicle on the route (step S110). Specifically, for example, it is determined whether a curve exists within 500 meters.

  When the curve exists within X meters, the curve information acquisition unit 21c acquires the curve information of the first curve closest to the vehicle as viewed from the position of the host vehicle (step S115). Specifically, for example, information indicating the distance from the position of the host vehicle to the first curve and the turning direction of the host vehicle in the first curve (for example, turning right or turning left) is acquired. If it is not determined in step S110 that a curve exists within X meters, the vibrating body control process is terminated.

  Next, the curve information acquisition unit 21c determines whether the second curve exists within Y meters from the first curve (step S120). Specifically, for example, it is determined whether the next curve exists within 200 meters ahead of the first curve on the route. When the second curve exists, the curve information acquisition unit 21c acquires the curve information of the second curve (step S125). Specifically, for example, information indicating the distance from the first curve to the second curve and the turning direction of the host vehicle in the second curve is acquired. When it is determined that the second curve does not exist, the process proceeds to step S140.

  Next, the curve information acquisition unit 21c determines whether or not the third curve exists within Y meters from the second curve (step S130). Specifically, for example, it is determined whether the next curve exists within 200 meters from the second curve on the route. When the third curve exists, the curve information of the third curve is acquired (step S135). Specifically, for example, information indicating the distance from the second curve to the third curve and the turning direction of the host vehicle in the third curve is acquired. If there is no third curve, the process proceeds to step S140. Finally, the vibrating body control unit 21d vibrates the vibrating body in a vibration mode corresponding to the acquired curve information (step S140).

  This vibrating body control process is a process repeatedly executed every elapse of a predetermined time, and therefore the current position of the host vehicle is updated every elapse of the predetermined time. In this embodiment, two or more right / left turn guidance intersections on a route are cases where each distance between adjacent intersections in the order of passage on the route is within 200 meters, and the first number of those consecutive intersections When the previous intersection is kept ahead of the vehicle within 500 meters, the vibrating body is controlled in the vibration mode set in step S140. Note that the vibration guidance according to the vibration mode set in step S140 may be repeatedly performed until the first intersection is passed, or may be performed only once before passing the first intersection. .

The flow of the vibrator control process shown in FIG. 3 has been described above. Next, the vibration mode of the vibrating body performed in step S140 when the above processing is executed will be described. FIG. 4 is a diagram for explaining an operation example by the vibrator control process, and shows a route of the host vehicle. In front of the position P of the host vehicle on the route, there is a first intersection I ₁ that is a right turn intersection at a distance D ₀ first, and a second intersection I that is a left turn intersection at a distance D ₁ from the intersection I _1. There are _two . Further there is a third intersection _{I 3} is a right turn intersection from the intersection _{I 2} a distance _{D 2} away. Further, the distance _{D 0} 500 meters distance _{D 1} 200 meters distance _{D 2} as is 150 meters for explaining an example of a vibration mode.

(2-1) Example of vibration mode 1:
FIG. 5A is a diagram showing an example of a vibration mode in the case of guiding the route as described above. The horizontal axis represents the time axis. The upper stage shows the vibration timing of the vibrating body 43b on the front right side of the seating surface, and the lower stage shows the vibration timing of the vibrating body 43a on the left side of the front surface of the seating surface. Vibration of the right vibrator for the driver seated to the effect that a right turn at the intersection I ₁ · I ₃ in the driver's seat, by transmitting instruction to turn left at the intersection I ₂ by vibration of the left vibrator, the driver It can be intuitively associated to turn right when the vibration of the vibrating body provided on the right side is felt, and to turn left when the vibration of the vibrating body provided on the left side is felt.

  Also, instead of generating vibrations corresponding to each curve at the same time, the vibration generation time is shifted and the vibrations are generated in order starting from the vibration corresponding to the intersection existing in front of the vehicle position. The driver can intuitively associate that the intersection corresponding to the vibration is located behind the intersection corresponding to the vibration felt first on the basis of the position of the host vehicle on the route. Moreover, it can be associated that the intersection corresponding to the vibration felt third is further behind.

Further, an interval (time T ₁ ) between the vibration corresponding to the intersection I ₁ and the vibration corresponding to the intersection I ₂ (time T ₁ ), and the interval (time T ₂ ) between the vibration corresponding to the intersection I ₂ and the vibration corresponding to the intersection I ₃ are set. By associating the distances D ₁ and D ₂ with each other, the driver can intuitively associate the distance between the curves. The distance _{D 1} is to indicate that longer than the distance _{D 2,} at least the time _{T 1} is set longer than the time _{T 2.}

  Furthermore, by performing guidance of the Mth curve (M is an integer not less than 1 and not more than N-1) -th curve near the position of the host vehicle by generating a predetermined unit vibration M times, for example, two units The driver can easily associate that the vibration is vibration corresponding to the second intersection from the position of the host vehicle. Note that the unit vibration may be vibration within a predetermined unit time, and the mode of vibration is not limited. That is, a specific vibration may be generated within a specific period so that the number of times can be counted, and the vibration may be continuous or discrete. The frequency and the intensity of vibration are arbitrary.

(2-2) Example 2 of vibration mode:
FIG. 5B is a diagram illustrating another example of the vibration mode. The description which overlaps with Example 1 of a vibration aspect is abbreviate | omitted, and demonstrates the characteristic of Example 2. FIG. In FIG. 5B, in order from the uppermost stage to the lowermost stage, the vibrating body 43f on the backrest upper right side, the vibrating body 43e on the upper left side of the backrest, the vibrating body 43d on the rear right side of the seating surface, the vibrating body 43c on the rear left side of the seating surface, and the right side on the front surface of the seating surface. The vibration timings of the six vibrating bodies 43b and the vibrating body 43a on the left side of the front part of the seating surface are shown.

As shown in FIG. 5B, the guidance of the _first intersection I ₁ from the front (closest to the own vehicle) with reference to the position of the own vehicle is the back vibration of the upper right vibrating body 43 f and the second intersection I ₂ . guiding vibration of the vibrating body 43c of the seating surface rear left side, carried out by the vibration of the vibrating body 43b of the seat presence section right side third guide intersection I _3. This is based on the position of the driver's seat that can be in contact with the head of the driver seated in the driver's seat (for example, a headrest) as the reference position, and the vibrators 43e and 43f provided closest to the reference position are the first. The second intersection of the vibrating bodies 43c and 43d provided at the second closest position from the reference position, and the third intersection of the vibrating bodies 43a and 43b provided at the third closest position from the reference position In the case of a right turn, the vibrating body on the right side is vibrated, and in the case of a left turn, the vibrating body on the left side is vibrated.

  In this way, the vibration provided at a position closer to the driver's head in the state where the driver is seated in the driver's seat, the vibration provided at a position farther from the driver's head at an intersection closer to the position of the host vehicle. By associating an intersection that is farther from the position of the host vehicle with the body, the driver can recognize that the vibration caused by the vibrating body closer to the head corresponds to the intersection closer to the position of the host vehicle.

(2-3) Example 3 of vibration mode:
FIG. 5C is a diagram illustrating another example of the vibration mode. The description which overlaps with Example 1 and Example 2 of a vibration aspect is abbreviate | omitted, and the characteristic of Example 3 is demonstrated. In Example 3, the vibration corresponding to the intersection located closer to the own vehicle on the route is stronger and the vibration corresponding to the intersection farther away is weaker. FIG. 5C shows that the vibration corresponding to the intersection I ₁ is the strongest and the vibration corresponding to the intersection I ₃ is the weakest. In this way, the driver can intuitively associate that the intersection corresponding to the strong vibration is closer to the host vehicle on the route than the intersection corresponding to the weak vibration. Note that the strong vibration refers to, for example, vibration with a large frequency or vibration with a large amplitude.

  As described above, according to the present embodiment, the driver can recognize that a plurality of intersections are continuously present in front of the host vehicle before approaching the plurality of intersections. Further, the driver can associate the mode of the intersection with the vibration mode. As a result, the driver can associate the driving operation performed when traveling at the intersection from the aspect of the intersection.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention, and obtains information indicating a plurality of curve modes existing continuously forward from the position of the host vehicle on the route, and corresponds to the plurality of curve modes. As long as the vibrating body provided at a position where the driver of the host vehicle can contact is vibrated, various other embodiments can be employed. For example, the selection method of the N vibrating bodies corresponding to the positions of the N curves with respect to the position of the host vehicle is not limited to the above-described example 2 of the vibration mode, and each of the N curves with respect to the position of the host vehicle is not limited. As long as the position can be associated with each position of the vibrating body with respect to the reference position of the seat on which the driver is seated, there is no particular limitation on the arrangement and quantity of the vibrating body and how to associate with each position. The vibration body provided at a position closer to the head may be associated with a curve farther from the host vehicle.

  When each intersection is associated with a different vibrating body as in the vibration mode example 2, the vibrations corresponding to each intersection may be simultaneously vibrated without providing a time difference. Even if a plurality of vibrating bodies vibrate simultaneously, different vibrating bodies vibrate, so that the driver can associate the position of the vibrating body and the order and distance of the intersection.

  Furthermore, in the above-described embodiment, the configuration in which route guidance is performed using a plurality of vibrators has been described, but the number of vibrators may be one. In this case, for example, only that there are N curves ahead of the host vehicle on the route is guided by repeating unit vibrations M times in order from the Mth, as in Example 1 and Example 3 of the vibration mode. May be. In other words, the configuration may be such that guidance on information about whether to turn left or right is omitted.

  In the above embodiment, the configuration in which the vibrating body is provided in the driver's seat has been described. However, the vibrating body is provided in the handle, for example, as shown in FIG. 5A or FIG. May vibrate the left side of the handle.

  Furthermore, the information indicating the route of the host vehicle may be information indicating a route that is likely to travel by the host vehicle, and is not limited to the recommended route obtained as a result of the search described in the above embodiment. Information indicating a travel schedule route manually set by the driver or information indicating an estimated route obtained from a past travel route by a learning process may be used.

  In the above-described embodiment, the configuration in which up to three consecutive intersections are guided in advance has been described. However, the number of intersections to be guided in advance by vibration may be two at the maximum or four or more. Good.
