Description

  The present invention relates to an intersection non-stop driving support system or the like in which an object of a system is achieved by accurately driving a vehicle between a starting point and a destination at a predetermined time, and a vehicle driver travels while driving from the starting point to the destination point. The present invention relates to a vehicle travel state information display method capable of accurately grasping the course of the vehicle and correcting an appropriate travel speed for ensuring arrival at a destination at a predetermined time.

  For energy saving, emission reduction, and traffic safety, “recommended requirements for non-stop passing through the intersection for each vehicle traveling at the fixed distance before the intersection toward the intersection. Various conditions necessary for calculating driving conditions or driving conditions such as time and recommended driving speed are calculated and reported for each vehicle, and the vehicle that receives the notification is necessary for the reported driving conditions or for calculating the reported driving conditions. An intersection nonstop traveling support system that calculates traveling conditions from various information, travels toward the intersection under the traveling conditions, and passes through the intersection in a nonstop manner without encountering a red light has been proposed.

  In this intersection non-stop driving support system, the vehicle is driven at a recommended traveling speed corresponding to the recommended required time for each vehicle from a certain distance before the intersection to the destination point, that is, the intersection to be passed next. When there is an error between the actual travel speed and the recommended travel speed, it is most important that the actual travel speed can be appropriately corrected to achieve arrival at the destination according to the recommended required time. However, in the method of comparing and displaying the recommended travel speed and the actual travel speed using the conventional in-vehicle display device, the method for correcting the recommended travel speed for reaching the target point in the recommended required time is unclear.

Japanese Patent Application No. 2004-212440 Japanese Patent Application No. 2005-63217 JP 2004-93422 A

  According to the present invention, in the intersection non-stop driving support system, a recommended traveling speed, an actual traveling speed, a recommended traveling distance, an actual traveling distance so that the vehicle can accurately arrive at the destination at the recommended time when traveling between the starting point and the destination point. The present invention relates to an accurate display method of vehicle travel state information such as travel distance, recommended required time, and actual travel time.

  That is, in the intersection non-stop driving support system, the vehicle travels at the recommended traveling speed corresponding to each vehicle in order to reach the destination point, that is, the intersection to be passed next from the starting point in the recommended required time. There is a need. More precisely, the average running average speed of the section becomes the recommended traveling speed at a speed below the maximum allowable speed without passing the specific section over the forward traveling vehicle or overtaking the following vehicle. It is necessary to travel as follows.

Therefore, during traveling between the starting point and the destination point, the recommended traveling speed corresponding to each vehicle and the actual traveling speed are simply displayed in comparison, and the driver only travels so that the actual traveling speed of the vehicle becomes the recommended traveling speed. The goal cannot be achieved. That is, once the actual travel speed deviates from the recommended travel speed, even if the actual travel speed is corrected to the recommended travel speed, the actual average travel speed between the starting point and the destination point does not match the recommended travel speed, and the intersection is accurate. Non-stop driving support will not be possible.
Here, for the accurate definition / calculation method of the recommended required time, recommended required speed, allowable maximum speed, recommended driving speed range, etc. corresponding to each vehicle in the intersection non-stop driving support system, see Japanese Patent Application No. 2004-212440. Since it is described in detail in Japanese Patent Application No. 2005-63217, description thereof is omitted here.

Also in the car navigation system, when the predicted travel time from the start point to the destination point is presented and the target travels, the predicted travel speed (= (start-point distance) / (predicted travel time)) and actual travel By simply displaying and comparing the speeds, the actual travel time from the starting point, the actual travel distance, etc. are unknown and the driver's request to travel in the predicted travel time cannot be satisfied.
The present invention provides an optimal vehicle traveling state information display method that solves the above problems.

The basic concept of the present invention is common to both the intersection non-stop driving support system and the car navigation system as follows.
That is, the actual travel distance from when the vehicle passes through to the present time is calculated and detected at regular intervals by, for example, time-integrating the number of vehicle speed pulses of the vehicle, and the recommended travel speed or predicted travel speed (= The total travel distance / predicted travel time) is compared and displayed for the recommended travel distance or the predicted travel distance.

  By displaying in this way, whether or not the actual mileage from the starting point to the current point is in line with the target, and if not, how much the target value is added or deficient should be corrected in the future. For example, it is possible to accurately inform the vehicle driver whether the destination can be reached at the recommended travel time or the estimated travel time, and the travel time information in the intersection non-stop driving support or the car navigation system can be effectively used.

First, the case of an intersection non-stop driving support system will be specifically described.
In the intersection non-stop driving support system, the actual driving distance from the starting point to the current time, and the recommended driving distance or the recommended driving distance range upper and lower limit values when traveling at the recommended driving speed or the recommended driving speed range upper and lower limit values are set for a certain time ΔT. Calculate and update every other time for comparison. By looking at this comparison display, the vehicle driver travels by adjusting the actual travel speed so that the actual travel distance matches the recommended travel distance or the actual travel distance falls within the upper and lower limits of the recommended travel distance range. In this case, however, it goes without saying that the actual traveling speed must not exceed the allowable maximum speed. By traveling in this way, the actual traveling speed deviation during traveling can be corrected, and the actual traveling average speed can be matched with the recommended traveling speed, that is, arrival at the destination point within the recommended required time can be facilitated.

  In the above description, the actual travel distance and the recommended travel distance or the upper and lower limit values of the recommended travel distance range are compared and displayed. It is equivalent.

  In addition, a time-distance plane is formed on the display device, and the travel distance characteristics Lr (t) or Lrmax (t) when traveling at the recommended travel speed from the starting point to the destination or the recommended travel speed range upper and lower limit values, There is also a method of displaying Lrmin (t), and updating and comparing / displaying the mileage characteristic Ls (t) by actual traveling from the starting point to the present time at a constant time ΔT. This display method clarifies the actual travel progress with respect to the travel progress that should be the target from the starting point, and the method of correcting the travel toward the future destination point of the vehicle driver.

  In other words, the vehicle driver must make sure that the travel distance characteristic Ls (t) due to actual travel matches the travel distance characteristic Lr (t) due to travel at the recommended travel speed or within the travel distance characteristic range due to travel within the recommended travel speed range upper and lower limit values. By traveling, it is possible to arrive at the destination within the recommended required time or within the recommended required time allowable range so that the travel distance characteristic Ls (t) by actual driving is entered in Lrmin (t) to Lrmax (t).

The same applies to the travel time display in the car navigation system.
Update the actual travel time to the present with respect to the estimated travel time between the start point and the destination point, and the actual travel distance to the present with respect to the distance between the start point and the destination point at regular time intervals or every constant distance travel. Compare and display.
Alternatively, as in the case of the intersection non-stop driving support system, a time-distance plane is formed on the display device screen, and an estimated travel time-travel distance characteristic from the starting point to the destination point is displayed on the time-distance plane. The distance characteristics may be updated at regular intervals for comparison / display.
From this, it becomes clear whether the travel up to the present time is faster or slower than the predicted travel time, and how to travel in the future in order to reach the destination as predicted.

Further, in the intersection non-stop traveling support system, a vehicle that travels following an intersection non-stop traveling with a regular inter-vehicle distance can pass non-stop at an intersection to be passed next with a special exception.
However, as a special case, if the vehicle that is traveling non-stop at the intersection is scheduled to pass the next intersection just before the green light at the intersection is extinguished, in other words, the actual traveling speed of the vehicle that is traveling non-stop at the intersection Is excluded if it is very close to the maximum permissible speed.

  In this special case, if the vehicle following the vehicle that is traveling non-stop at the intersection follows the vehicle that is traveling non-stop at the intersection, the vehicle that is traveling non-stop at the intersection is just before the green light extinction. This is because the intersection will reach the intersection immediately after passing through the intersection, and at this time, the intersection may have the green light changed to red. (For details of this reason, see Japanese Patent Application Nos. 2004-212440 and 2005-63217)

  Therefore, a vehicle traveling at the recommended travel speed knows the intersection arrival time that should pass next to the vehicle at the same time when calculating the recommended travel speed, or compares the recommended travel speed acquired by the vehicle with the maximum allowable speed, The arrival time is displayed on the following vehicle only when there is enough room to allow the following vehicle to pass by the same green light or when the recommended traveling speed of the own vehicle is not very close to the maximum allowable speed. The following display is not performed when there is no allowance at the intersection arrival time or when the recommended traveling speed is close to the allowable maximum speed. This method is very effective for improving the practicality of the intersection non-stop driving support system.

As described above, the present invention can improve the feasibility of the intersection non-stop traveling support system, and can greatly reduce the load of the vehicle driver for traveling the vehicle while maintaining the recommended traveling speed or the recommended traveling speed range.
In the car navigation system, the travel time information can be effectively used, and the convenience for the user can be greatly improved.

In the intersection non-stop driving support system, in addition to displaying the recommended driving speed or the recommended driving speed range upper and lower limit values and the actual driving speed on the in-vehicle display device, in addition to the recommendation on the time-distance plane according to the present invention. The travel distance characteristic Lr (t) or the recommended travel distance range upper / lower limit characteristic Lrmax (t), Lrmin (t) and the actual travel distance characteristic Ls (t) are compared and displayed.
In addition, a display device for displaying “intersection non-stop traveling” for the following vehicle is provided at the rear of the vehicle.
The travel time display in the car navigation system displays the predicted travel time and the actual required time up to the current time, and the distance to the destination and the actual travel distance up to the current time.

  Here, the “recommended travel distance”, “actual travel distance”, “recommended travel distance range”, and “actual travel distance” are supposed to be “recommended travel speed” in the explanation display of 303, 304, 307, and 308, respectively. ”,“ Actual travel average speed ”,“ Recommended travel speed range ”,“ Actual travel average speed ”are (actual travel distance from the start point to the current point) / (recommended travel distance from the start point to the present point) = (Actual average traveling speed up to the current time after passing through the starting point) / (recommended traveling speed up to the current time after passing through the starting point).

Therefore, the functional block diagram of FIG. 1 is changed as shown in FIG. 4, and there is a method of directly comparing the recommended travel speed and the actual travel average speed as shown in the explanation instead of the comparison calculation of the recommended travel distance and the actual travel distance.
In FIG.
404 receives the recommended travel speed vopt and the actual travel distance calculation unit 403 output Ls (t), and every time a ΔT elapsed signal of the ΔT timer 401 is output, the actual travel distance calculation unit 403 output Ls (t) at that time That is, Ls (ΔT), Ls (2ΔT), Ls (3ΔT),...

Here, 401 and 403 are the same as 101 and 103 in FIG.

  In the functional block diagram of FIG. 2, it is needless to say that the recommended travel distance range upper and lower limits and the actual travel distance can be displayed in comparison with the recommended travel speed range upper and lower limits and the actual travel average speed. .

  With the above display, the vehicle driver can know how much the actual running average speed up to the present time after passing through the starting point was in excess or deficiency compared to the recommended running speed. 3 (a), the actual traveling average speed display 304 matches the recommended traveling speed display 303, and in FIG. 3 (b), the actual traveling average speed 310 falls within the recommended traveling speed range 307 to 308. Each vehicle can travel accurately to the destination in the recommended time required.

A display example of Example 2 is shown in FIGS. 5 (a) and 5 (b).
In FIG. 5 (a), the current actual traveling speed display 502 is displayed on the display screen 501, and at the same time, a time-travel distance plane 505 having a horizontal axis time 503 and a vertical axis travel distance 504 is formed. In a non-stop driving system at a point or intersection, a driving distance characteristic Lr (t) 506 based on a recommended driving speed, and a driving distance characteristic Ls (t) 507 based on actual driving from the starting point to the present point, a predicted driving distance from the present point to the destination point The characteristic Ls (t) 508 is updated and compared / displayed for each predetermined time ΔT.
Here, the travel distance characteristic Ls (t) 508 predicted from the present time to the target point is the value of the travel distance characteristic Ls (t) 507 at the current time t from the starting point to the present time and the recommended travel distance characteristic Lr (t). It is obtained by connecting the value of the target point distance value at the recommended required time topt.

  The functional block diagram of the vehicle running state display related part for realizing this display example is the same as FIG. However, the content displayed on the display unit 405 is the travel distance characteristic Lr (t) on the time-travel distance plane instead of the recommended travel speed vopt, and the actual travel average speed Ls (ΔT) / (ΔT), Ls (2ΔT ) / (2ΔT), Ls (3ΔT) / (3Δ),..., Instead of the actual travel distance characteristic Ls (t) on the time-travel distance plane.

  In FIG. 5B, the current actual traveling speed display 510 is displayed on the display screen 508, and at the same time, a time-travel distance plane 513 having a horizontal axis time 511 and a vertical axis travel distance 512 is formed. The travel distance characteristic Lrmax (t) 514 and the travel distance characteristic Lrmin (t) 515 according to the recommended travel speed range upper limit value voptmax and the recommended travel speed range lower limit value voptmin in the non-stop travel system at the destination point, that is, from the start point to the present time The travel distance characteristic Ls (t) 516 by traveling and the travel distance characteristic Ls (t) 517 by prediction from the current point to the destination point are updated and compared / displayed for each predetermined time ΔT.

  By this comparison and display, the actual driving state from the time of passing through the starting point to the present time is clarified. When the vehicle driver drives to the destination point in the future, in the case of the display of FIG. In the display shown in FIG. 5 (b), when the travel distance characteristic 517 by actual travel is within the allowable error range of the recommended travel time topt when arriving at the destination point, the intersection non-point is obtained. Stop driving can be achieved.

  In addition, although the display example regarding the intersection non-stop traveling was described in the second embodiment, the travel time display in the car navigation system can be performed in the same way. That is, in the car navigation system, instead of the recommended travel speed in the intersection non-stop travel system, the predicted travel speed (= (distance between start point and destination point) / (predicted travel time)) may be used.

A display example of Example 3 is shown in FIG. This example is an example of the car navigation system of the present invention.
In FIG. 6, the actual travel time 604 from the start point to the present time with respect to the predicted travel time 602 is displayed on the display screen 601, and the remaining time with respect to the predicted travel time, that is, (predicted travel time) − (actual travel distance to the current time). 605, and the actual travel distance 606 to the current time with respect to the total travel distance 603 from the starting point to the destination point, the remaining distance 607 with respect to the total travel distance, that is, (total travel distance)-(actual travel distance to the current time), Each is shown in comparison.

  The same display is also used in the intersection non-stop driving system so that the driver's ratio of the actual elapsed time to the recommended required time matches the ratio of the starting point-to-target point driving distance to the starting point--target point distance. It is also possible to travel non-stop at the intersection by traveling in

As described above, the present invention can improve the feasibility of the intersection non-stop driving support system and greatly reduce the load on the vehicle driver to reach the destination in the recommended required time.
In the car navigation system, the travel time information can be effectively used, and the convenience of the car navigation system user is greatly improved.
