Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a notification device for a navigation system that guides a travel route of a vehicle from a current position to a destination set via a display, and in particular, provides a guidance direction when passing through an intersection on a driver's seat. The present invention relates to an apparatus that effectively supports route guidance by driving and notifying a vibrating body.
[0002]
[Prior art]
  Conventionally, a navigation system for a vehicle such as an automobile is divided into a plurality of areas, such as road guidance information such as major intersections and interchanges, that is, map information is provided in the control device as fixed information, and from a current location to a set destination Based on the travel route (travel route) of the vehicle, the map is displayed on the display while sequentially switching, and the travel route of the vehicle is displayed on the map by overlapping the travel route. To guide you.
[0003]
  By the way, recently, when a route is guided based on the moving route, when the intersection approaches, the distance to the intersection, the name of the intersection, and the turning direction are displayed on a part of the display, and Japanese Patent Laid-Open No. 7-209007. As described in the "Navigation device", an intersection guidance function that guides you to "Pawn !, approximately 300m, right on the Umeda intersection" is also added by voice. You can definitely pass in the direction along. In this case, the intersection direction guidance starts approximately 700 m before, and the intersection guidance is performed by display and voice over a plurality of times, such as a position 300 m before and a position 100 m before.
[0004]
  Here, in general, a car radio and an audio device are generally provided as a standard or an option, so that driving can be enjoyed while listening to radio broadcasting or listening to favorite music. That is, the driver often drives the car while looking at the movement route displayed on the display by the navigation system and listening to favorite music.
[0005]
[Problems to be solved by the invention]
  As described above, when a vehicle equipped with a navigation system is used to travel to a destination based on the travel route displayed on the display, the driver checks the front and sides visually, and further backs up with a rearview mirror. While traveling while confirming, the user will see the moving path of the display and may overlook the distance to the intersection and the guidance direction at the intersection. In particular, when the intersections are continuous, the guidance directions at these intersections may be displayed at the same time, and there is a problem that the guidance direction at the next intersection is not known.
[0006]
  On the other hand, as described in Japanese Patent Application Laid-Open No. 7-209007, intersection guidance is performed by voice, but when listening to car radio or favorite music, if the volume is loud, the intersection guidance by voice is missed. It also happens. Therefore, it is conceivable to increase the voice of the intersection guidance, but there is a problem that it causes trouble for passengers listening to music. Especially for hearing impaired people, they rely solely on the guidance display at the intersection, but as mentioned above, they will see the moving path of the display between runs, and they will miss the direction of guidance at the next intersection. There is a problem that it disappears and panics when approaching the intersection.
[0007]
  It is an object of the present invention to be able to notify a driver by vibrating a vibrating body when guiding a moving path through which a vehicle moves through a display, to be able to notify the guidance direction at each intersection by the vibration of the corresponding vibrating body, Prior to vibration by the body, it can be notified by the seat belt, the degree of approach to the intersection can be notified by the magnitude of vibration, the vibration form of the vibration body can be corrected according to the driving state of the automobile, and the bending angle of the intersection is driven by the vibration body It can be notified by the period.

  Next, the vibrating bodies 25 to 27 provided on the driver's seat 22 will be described with reference to FIGS.
  The driver's seat 22 includes a horizontal seat cushion 23 on which the driver sits during driving, and a seat back 24 that is pivotally supported by a rear end portion of the seat cushion 23 and supports the driver from the rear side. It is made up of.
[0034]
  Then, circular recesses are formed in the left and right surface portions where the driver's left and right thighs are in contact with each other in the vicinity of the front end of the seat cushion 23. , R vibration body) 25 is provided, and a cylindrical left vibration body (hereinafter referred to as L vibration body) 26 is provided in the left concave portion. Further, a circular concave portion is formed in the vicinity of the lower end of the seat back 24 and in the central portion in the width direction where the driver's waist is in contact, and one central vibrating body (hereinafter referred to as a W vibrating body) 27 is formed in the concave portion. Is provided.
[0035]
  Since these vibrating bodies 25 to 27 have the same configuration, the R vibrating body 25 will be described. As shown in FIG. 3, an electric circular magnet 31 having a thin coil built in a protective case 30, and this magnet An eccentric weight 32 that functions as a rotor pivotally supported by 31 is provided. That is, when a drive signal is supplied to the magnet 31 from the drive circuit 14 (see FIG. 1) via the connection cord L, the eccentric weight 32 is rotationally driven by the cooperation of the magnet 31 and the eccentric weight 32. The entire R vibrator 25 is vibrated by the centrifugal force acting on the eccentric weight 32 during this rotation.
[0036]
  Here, the magnet 31, the eccentric weight 32, etc. act as a drive motor. Furthermore, the rotational speed of the eccentric weight 32 can be changed by changing the frequency or voltage of the drive signal supplied to the magnet 31, thereby changing the drive gain G (vibration magnitude) of the vibrating bodies 25 to 27. Can do.
  On the other hand, the electric seat belt device 35 for the driver sitting on the driver's seat 22 will be briefly described. As shown in FIG. 4A, one end of the seat belt 36 is fixed to the fixing portion 37. The seat belt retractor 40 is wound around the buckle portion 38 and the shoulder support portion 39.
[0037]
  Here, as shown in FIG. 4B, the retractor 40 is connected to a drive motor 41 connected to the drive circuit 17, and the tension of the seat belt 36 is driven by driving the drive motor 41. Can be changed. By the way, the seat belt 36 can be vibrated by repeating the forward rotation and the reverse rotation at a high speed for each minute time.
  Next, a notification control routine executed by the control unit CU will be described with reference to the flowcharts of FIGS. In the figure, reference sign Si (i = 1, 2, 3,...) Indicates each step.
[0038]
  When the navigation system 1 is turned on, the route guidance control program described above is executed first, and after preparation work necessary for route guidance, such as setting a destination, is performed, a map and a movement are displayed on the liquid crystal display 9. The route is displayed, and the vehicle is guided based on the displayed moving route and starts moving toward the destination. Simultaneously with the start of this movement, notification control is started.
  When this control is started, first, partial movement route data ahead of a predetermined distance (for example, about 1 km) from the current position is read based on the set movement route data (S1).
[0039]
  Next, based on the partial movement route data, when not approaching the destination (S2: No), when road traffic information is received by the light / radio beacon receiver 13 (S3: Yes), the W vibrator 27 is driven in the first pattern for a predetermined time (S4). That is, as shown in FIG. 9, the W vibrating body 27 vibrates with a drive gain G of G0 (minimum gain at which the driver can feel vibration), such as “Beep, Beep,... For example, the first pattern in which the period is continued twice is vibrated for about 3 seconds. Thereby, it is notified that the road traffic information has been received.
[0040]
  By the way, when there is no intersection from the current position to a position ahead of the predetermined distance (S5: No), S1 to S5 are repeatedly executed. When an intersection is detected ahead (S5: Yes), the distance X from the current position to the next intersection is calculated based on the intersection information and the partial movement route data (S6). When this intersection distance X is 700 m or more which is the notification preparation distance (S7: No), the process returns to S1 without any notification.
[0041]
  However, when the intersection distance X has been shortened to less than 700 m which is the notification preparation distance, but is 300 m or more which is the predetermined notification distance (S7: No, S8: Yes), when the drive motor 41 is not driven in a vibrating manner (S13: No), the seat belt 36 of the retractor 40 is vibrated by repeatedly driving the drive motor 41 forward and backward at high speeds every minute time (S14). Next, the W vibrating body 27 is driven in the second pattern (S15). That is, as shown in FIG. 9, the W vibrating body 27 has a drive gain G of “G0” and the vibration period is continued three times at a time, such as “Beep Beep, Beep Beep,... It is vibrated by the second pattern. Thereby, the next intersection is not approached to the predetermined notification distance, but is notified that it is within the notification preparation distance.
[0042]
  Here, the W vibration body 27 actually vibrates after the warning is made through the vibration of the seat belt 36 of the seat belt retractor 40 as the vehicle approaches the intersection. The uncomfortable feeling can be effectively reduced with a simple mechanism. By the way, when moving to the predetermined notification distance toward the intersection, based on the vehicle speed signal, when the traveling state is changed, processing for changing the vibration mode of the drive gain G of the W vibrating body 27 is executed according to the change. (S16).
[0043]
  That is, in this vibration form changing process, the drive gain G of the W vibrator 27 is driven with a gain slightly weaker than the gain G0 in the acceleration state, and is more than the gain G0 in the deceleration state. It is driven with a gain slightly increased by (Δ). On the other hand, when the vehicle speed returns from the acceleration state or the deceleration state to the steady state, the vehicle returns to the original drive gain G0 and is driven.
  Next, when the intersection distance X is shortened to less than the predetermined notification distance of 300 m (S7 / S8: No, S9: Yes), the W vibrator 27, the R vibrator 25, Each of the L vibrating bodies 26 is driven.
[0044]
  That is, using the distance as a parameter, a notification point is set at a point about 300 m before the intersection, and when the route guidance is performed before each intersection, the W vibrator 27 is driven before reaching the notification point, After reaching the notification point, the vibrators 25 to 27 are selectively driven according to the guidance direction.
  When the guidance direction at the next intersection is a left turn (S17: left turn), the L vibrator 26 is driven under the driving condition of the driving gain G of “G0” and the driving cycle T of “T0”, and in the third pattern. Driven (S18).
[0045]
  As shown in FIG. 9, the third pattern has a driving cycle T0 of about 2 seconds, and periodically repeats the vibration period with a driving gain G of G0, such as “Beep, Beep, Beep, Beep, ...”. To vibrate. That is, the vibration of the L vibrating body 26 can accurately and reliably recognize that the guidance direction at the next intersection is the “left direction”.
[0046]
  Further, when the guidance direction at the next intersection is a right turn (S17: right turn), the R vibrating body 25 is driven under a driving condition where the driving gain G is “G0” and the driving cycle T is “T0”, and in the third pattern. Driven (S19). That is, the vibration of the R vibrating body 25 can accurately and reliably recognize that the guidance direction at the next intersection is the “right direction”. When the traveling state is changed based on the steering angle signal while moving toward the intersection until the intersection distance X reaches 300 m to 101 m, the driving of the R vibrating body 25 or the L vibrating body 26 is changed according to the change. A process of changing the vibration mode of the gain G is executed (S20).
[0047]
  That is, in this vibration mode changing process, when the R vibrating body 25 is driven in the right turn state, the drive gain G is driven with a gain slightly increased (Δ) from the drive gain G0. Alternatively, when the L vibrator 26 is driven, the drive gain G is driven with a gain slightly weaker than the drive gain G0 by (Δ). Conversely, when the R vibrating body 25 is driven in the left turn state, the driving gain G is driven with a gain slightly weaker than the driving gain G0 (Δ), or the L vibrating body. When the drive 26 is driven, the drive gain G is driven with a gain slightly increased by (Δ) from the drive gain G0.
[0048]
  By the way, when returning to the straight traveling state, the driven R vibrating body 25 or L vibrating body 26 returns to the original driving gain G0 and is driven. On the other hand, when the guidance direction at the next intersection is straight (S17: straight), the W vibrating body 27 is driven under the driving condition where the driving gain G is “G0” and the driving cycle T is “T0”, and in the third pattern. Driven (S21). In other words, the vibration of the W vibrating body 25 can accurately and reliably recognize that the guidance direction at the next intersection is “straight forward”.
[0049]
  When the traveling state is changed based on the vehicle speed signal while moving toward the intersection until the intersection distance X reaches 300 m to 101 m, the vibration of the drive gain G of the W vibrating body 27 is changed as in S16. A process of changing the form is executed (S22). Next, when the intersection distance X is shortened to less than 100 m (S7 to S9: No, S10: Yes), the currently driven W vibrating body 27, R vibrating body 25, or L vibrating body 26 has a drive gain G. Is driven in the third pattern under the driving condition of “G1” and the driving cycle T is “T0” (S23). Here, drive gain G1> drive gain G0.
[0050]
  When the traveling state such as acceleration or deceleration is changed while moving toward the intersection until the intersection distance X reaches 50 m, the driving gain G of the W vibrating body 27 is accelerated as in the case of S22. A process for changing to the drive gain (G1−Δ) at the time of deceleration is executed (S24) while sometimes changing to the drive gain (G1 + Δ). Further, when the traveling state such as right turn or left turn is changed, the drive gain G of the driven R vibrating body 25 or L vibrating body 26 is set to the drive gain (G1 + Δ) in substantially the same manner as S20. ) Or processing for changing to drive gain (G1−Δ) is executed (S25).
[0051]
  Next, when the intersection distance X is reduced to less than 50 m (S7 to S10: No, S11: Yes), the currently driven W vibrating body 27, R vibrating body 25, or L vibrating body 26 has a drive gain G. Is driven with the third pattern under the driving condition where “G2” is set to “G2” and the driving cycle T is “T0” (S26). Here, drive gain G2> drive gain G1. While moving toward the intersection until the intersection distance X reaches 50 m, the drive gain G of the W vibrating body 27 is changed to the drive gain (G2 + Δ) during acceleration while the drive gain during deceleration while moving toward the intersection. The process of changing to (G2−Δ) is executed (S27).
[0052]
  Further, in substantially the same way as S25, when turning right or left, the drive gain G of the driven R vibrating body 25 or L vibrating body 26 is set to drive gain (G2 + Δ) or drive gain (G2−Δ). ) Is changed (S28).
  Next, when the intersection distance X is shortened to less than 30 m (S7 to S11: No, S12: Yes), the currently driven W vibrating body 27, R vibrating body 25, or L vibrating body 26 has a drive gain G. Is driven with the third pattern under the driving condition where “G3” is set to “G3” and the driving cycle T is “T0” (S29). Here, drive gain G3> drive gain G2.
[0053]
  While moving toward the intersection until the intersection distance X reaches 10 m, the drive gain G of the W vibrating body 27 is changed to the drive gain (G2−Δ) at the time of acceleration while driving at the time of deceleration as in S27. A process of changing to the gain (G2 + Δ) is executed (S30). Further, in substantially the same way as S28, when turning right or left, the drive gain G of the driven R vibrating body 25 or L vibrating body 26 is set to the driving gain (G3 + Δ) or the driving gain (G3−Δ). ) Is changed (S31).
[0054]
  Finally, when the intersection distance X reaches 10 m (S7 to S12: No), the currently driven W vibrating body 27, R vibrating body 25, or L vibrating body 26 sets the drive gain G to “G4. And the driving cycle T is driven under the driving condition of “Tα” set according to the turning angle of the intersection (S32). Here, drive gain G4> drive gain G3. Here, the turning angle of the intersection is obtained based on the map information and the intersection information. Further, as shown in FIG. 10, the driving cycle Tα corresponding to the turning angle of the intersection is obtained by calculation based on the data of the driving cycle table with respect to the turning angle of the intersection.
[0055]
  That is, when the turning angle is such that a general cross-shaped intersection turns at a substantially right angle (90 °), the normal driving cycle T is “T0”, but the driving cycle T is set shorter as the turning angle increases. Next, based on the current position and the partial movement route data, S32 to S33 are repeatedly executed until the intersection is passed (S33: No). When the vehicle passes through the intersection (S33: Yes), the driving of the driven W vibrating body 27, R vibrating body 25 or L vibrating body 26 is stopped (S34), and the process returns to S1.
  By the way, based on the read partial movement route data, when the destination approaches, for example, about 200 m to 300 m ahead (S2: Yes), the W vibrating body 27 is driven in the fourth pattern (S35).
[0056]
  That is, as shown in FIG. 9, the W vibrating body 27 is driven by the fourth pattern in which the driving gain G is “G0” and the vibration period is continuous, such as “B ...”. The fact that the destination is approaching is notified by the vibration of the W vibrating body 27 by the fourth pattern. Next, similarly to S16, the process of changing the drive gain G of the W vibrator 27 to the drive gain (G2−Δ) at the time of acceleration while changing to the drive gain (G2 + Δ) at the time of deceleration is executed (S36). ). And while moving (S37: No) until it arrives at the destination, S35-S36 are repeatedly performed. Finally, when the vehicle arrives at the destination (S37: Yes), the driving of the W vibrator 27 is stopped (S38), and the process returns to S1.
[0057]
  Next, the effect | action of alerting | reporting control at the time of the route guidance by the navigation system 1 comprised in this way is demonstrated.
  For example, as shown in FIG. 11, the liquid crystal display 9 displays a road map in the vicinity of the current position while traveling, and the travel route ML to be guided to the destination is displayed by, for example, “red thick line”. Furthermore, the current positions V1 to V7 of the host vehicle are displayed with “red triangle marks”. At this time, it is assumed that there is an intersection K that bends to the left in an acute angle in front of the traveling road. However, it is assumed that there is a left curve LC and a right curve RC on the way to the intersection K.
[0058]
  Then, when the vehicle travels to the vehicle position V1 by the route guidance by the movement route ML, that is, when the vehicle approaches the distance X of about 700 m with respect to the intersection K, first, the vibration of the W vibrating body 27 is notified in advance. From immediately after the seat belt 36 of the tractor 40 is vibrated, the W vibrating body 27 is moved from the vehicle position V2 that is a notification point (a position about 300 m before the intersection K to a predetermined notification distance) to the first position. Driven in two patterns. During this movement, the drive gain G is changed to the drive gain (G0−Δ) during acceleration, and is changed to the drive gain (G0 + Δ) during deceleration.
[0059]
  That is, when the driver swings rearward due to acceleration and presses the W vibrating body 27, the W vibrating body 27 is driven with a weak driving gain (G0−Δ), while the driver is driven by deceleration. When swinging forward and moving away from the W vibrating body 27, the W vibrating body 27 is driven with a strong drive gain (G0 + Δ), so that the magnitude of vibration transmitted to the driver is substantially constant, and at the intersection. The direction of guidance can be constantly notified to the driver.
[0060]
  And since it makes a left turn at the intersection from the time when it travels to its own vehicle position V2 until it moves to its own vehicle position V3 (approximately 100 m before intersection K), the L vibrator 26 has a drive gain G0 and a drive cycle T0. Driven. By moving the left curve LC in the middle of the movement, when the vehicle turns left, the left leg thigh is lifted up as the driver swings to the right, but the drive gain G of the L vibrator 26 is increased. By changing to (G0 + Δ), the L vibrating body 26 vibrates more greatly, so that the vibration of the L vibrating body 26 can be notified to the driver with substantially the same strength.
[0061]
  Next, the vehicle makes a left turn at the intersection from the time when the vehicle travels to the vehicle position V3 until the vehicle moves to the vehicle position V4 (approximately 50 meters before the intersection K), so that the L vibrator 26 has the drive gain G1 and the drive cycle T0. It is driven by. By moving the right curve RC in the middle of the movement, when the vehicle turns to the right, the thigh of the left leg sinks into the seat cushion 23 as the driver swings to the left side. Since the drive gain G is changed to (G1−Δ) and the L vibrating body 26 vibrates to a smaller extent, the vibration of the L vibrating body 26 can be notified to the driver with substantially the same strength.
[0062]
  Next, the vehicle makes a left turn at the intersection from the time when the vehicle travels to the vehicle position V4 until the vehicle moves to the vehicle position V5 (approximately 30 meters before the intersection K). Therefore, the L vibrating body 26 has the drive gain G2 and the drive cycle T0. It is driven by. Further, since the vehicle turns left at the intersection from the time when the vehicle travels to the vehicle position V5 to the time when the vehicle moves to the vehicle position V6 (approximately 10 m before the intersection K), the L vibrating body 26 has the drive gain G3 and the drive cycle T0. Driven. From the time when the vehicle travels to the vehicle position V6 to the time when the vehicle moves to the vehicle position V7 that passes through the intersection K, the L vibrator 26 is driven with a drive gain G4 and a drive cycle Tα that is slightly shorter than T0. As a result, it can be seen that the intersection K bends slightly sharply.
[0063]
  Here, the notification control and the control unit CU shown in FIGS. 5 to 8 correspond to the notification control means, and the retractor 40 that winds up the seat belt 36, the drive motor 41 that rotationally drives the retractor 40, and the like add vibration. This vibration adding means corresponds to the notice means. Further, the notification device is configured by the control unit CU, the notification control program, the vibrating bodies 25 to 27, and the like.
[0064]
  As described above, the R vibrating body 25 and the L vibrating body 26 are provided in different portions on the seat cushion 23 of the driver's seat, and the W vibrating body 27 is provided at the center in the width direction of the seat back 24 of the driver's seat. When the distance from the current position to the intersection is a predetermined notification distance (for example, about 300 m) or more, the W vibrating body 27 of the seat back 24 is driven. It is possible to reliably notify that it is present.
[0065]
  In addition, since the distance from the current position to the intersection is less than the predetermined notification distance, the W vibrating body 27, the R vibrating body 25, and the L vibrating body 26 are driven in accordance with straight travel, right turn, and left turn, respectively. Even if the driver overlooks the movement route ML displayed on the liquid crystal display 9 or misses the intersection guidance by voice, as long as the driver is sitting on the driver's seat 22 in any posture, the next intersection is reached. Can be informed that the distance has been approached within the predetermined notification distance, and at the same time, the guidance direction at the intersection can be effectively and reliably notified. In addition, passengers who are listening to radio broadcasting and music will not bother passengers other than the driver.
[0066]
  In particular, when a hearing-impaired person drives, even if the guidance direction at the next intersection displayed on the display is overlooked, the guidance direction at the intersection can be reliably notified by the vibration of the vibrating body. Moreover, since only one vibrating body 25 to 27 is driven to notify the guiding direction, the guiding direction can be effectively notified by a small number of vibrating bodies, and driving when driving these vibrating bodies 25 to 27 is performed. Electric power can be minimized.
[0067]
  In addition, since the W vibrating body 27 actually vibrates after the warning is issued through the vibration of the seat belt 36 of the seat belt retractor 40, the driver's surprise and uncomfortable feeling can be easily and effectively realized by the warning. Can be relaxed.
  Furthermore, since the driving cycle T of the vibrators 25 to 27 is shortened as the turning angle of the intersection K is larger, the degree of the bending angle can be effectively and easily notified by the driving cycle T.
[0068]
  Next, a modified embodiment in which the embodiment is partially modified will be described.
1] The predetermined notification distance at the time of route guidance may be configured to be arbitrarily set by the driver manually, or may be corrected so as to increase as the traveling speed increases.
2] When going straight at the intersection, the three vibrators 25 to 27 may be simultaneously driven to notify the user.
3] A pair of left and right vibrating bodies (WR vibrating body and WL vibrating body) is provided on the seat back 24, and the WR vibrating body and the R vibrating body 25 are simultaneously driven when turning right, while the WL vibrating body and the L vibrating body when turning left. 26 may be driven simultaneously. Alternatively, a plurality of vibrators may be provided in different portions of the seat cushion 23 and the seat back 24, and a combination of these may be vibrated to notify a right turn or a left turn.
[0069]
4] Prior to vibrating the vibrating bodies 25 to 27 when approaching the intersection, a warning is given by sounding a buzzer or flashing a lamp instead of the warning vibration of the seat belt 36 by the seat belt retractor 40. You may do it.
5] The drive gain G of the vibrating bodies 25 to 27 may be continuously increased as the intersection is approached.
6] The basic drive gain G0 of the vibrators 25 to 27 can be set to an arbitrary size by manual operation according to the driver's preference, according to the driver's favorite size. Good.
[0070]
7] When passing through the intersection and moving away from the intersection, the drive gain G of the vibrators 25 to 27 may be gradually decreased and the drive cycle T may be gradually increased.
8] When traveling on an expressway, the approach of a branch or an interchange may be notified by the vibrations of the vibrators 25 to 27, and may be driven with a vibration pattern different from that of a general road.
[0071]
9] The notification point described above may be set as a parameter time to reach each intersection determined by taking the vehicle speed into account. That is, based on the current traveling speed (for example, about 50 km / hour), a notification point is set at a point (for example, about 400 m before the intersection) before a predetermined time (for example, about 30 seconds) before reaching the intersection. You may do it. In this case, especially when the vehicle is congested and the traveling speed is slow, the notification point is provided at a point very close to the intersection (for example, 20 to 30 meters before), and the seat cushion vibrating body at an optimal time related to the vehicle speed. Can be effectively notified of the guidance direction at the intersection.
[0072]
10] The vibrating bodies 25 to 27 may be constituted by actuators that generate vibrations electrically, such as piezoelectric elements and solenoids.
11] The storage medium for storing the map information and the audio information may be various media capable of storing information at a high density, such as a DVD (digital video disk).
12] The present invention should not be construed as being limited to the above-described embodiments and modifications, and within the scope of the technical idea of the present invention, existing techniques and those skilled in the art can be used to control each part of the above-described embodiments. However, various modifications may be made based on obvious technology.
