That is, it waits until the support point Q comes to exist around the vehicle C. On the other hand, when it determines with the assistance point Q existing around the vehicle C, the control part 20 determines whether the deceleration of the vehicle C was complete
- the case where the deceleration is completed means that the vehicle speed is equal to or lower than a predetermined threshold value (for example, 3 km / hour) or that the vehicle speed is decreased by a predetermined amount (for example, 5 km / hour) or more. This is when the accelerator pedal is depressed.

Further, the number of decelerations is the number of remaining distances L representing the position of the deceleration point A recorded as a travel log, and the number of passes is the number of “passes” recorded as a travel log.
- step S115: Y the control unit 20 learns that the target flag is turned on for the support point Q where the deceleration of the vehicle C has ended by the function of the exclusion unit 21c.
- Information is updated (step S120). That is, the control unit 20 updates the position of the support point Q, the target vehicle speed, and the target flag in the learning information. Specifically, the control unit 20 acquires a position corresponding to the median value of the remaining distance L representing the positions of the plurality of deceleration points A recorded as the learning log as the position of the new support point Q.
- control unit 20 adds the number obtained by subtracting 1 from the number of times of deceleration (number of times of deceleration-1) and the current target vehicle speed and the vehicle speed when it is determined that the deceleration is completed in step S105.
- the updated target vehicle speed is obtained by calculating the value and dividing the total value by the number of decelerations.
- the control unit 20 sets the target flag in the learning information to ON. That is, if the target flag is originally OFF, the target flag is switched to ON. If the target flag is originally ON, the target flag is kept ON. Thereby, deceleration support can be implemented at the support point Q where the vehicle C is highly likely to decelerate.
- step S115: N the control unit 20 causes the target flag to be turned off for the support point Q where the deceleration of the vehicle C is ended by the function of the exclusion unit 21c.
- the learning information is updated (step S125).
- the control unit 20 updates the target vehicle speed and the position of the support point Q as in step S120.
- step S125 the control unit 20 sets the target flag in the learning information to OFF. That is, if the target flag is ON, the target flag is switched to OFF, and if the target flag is originally OFF, the target flag remains OFF. Thereby, it is possible to prevent the vehicle C from being decelerated at the support point Q where the possibility that the vehicle C is decelerated is small.
- step S105: N when it is not determined that the deceleration of the vehicle C has been completed at the support point Q (step S105: N), the control unit 20 records “pass” as a travel log by the function of the exclusion unit 21c, and the new road The flag is set to OFF (step S130).
- the control unit 20 deletes the oldest remaining distance L or “passing”. , "Pass” is recorded as a new travel log.
- the control unit 20 sets the new road flag to OFF as an initial state.
- the control unit 20 determines whether the deceleration probability is less than the exclusion threshold (for example, 30%) (step S135).
- the control unit 20 sets the target flag for the support point Q where the deceleration has not been performed to OFF by the function of the exclusion unit 21c (step S135).
- S140 That is, if the target flag is ON, the target flag is switched to OFF, and if the target flag is originally OFF, the target flag remains OFF. Thereby, it is possible to prevent the vehicle C from being decelerated at the support point Q where the possibility that the vehicle C is decelerated is small.
- the exclusion threshold that is the deceleration probability when the target flag is switched from ON to OFF is set to a value smaller than the target threshold that is the deceleration probability when the target flag is switched from OFF to ON.
- step S135: N the control unit 20 uses the function of the exclusion unit 21c to drive the vehicle C on the new road section following the support point Q. It is determined whether or not (step S145). Specifically, after passing the support point Q, when the vehicle C has traveled a predetermined distance (for example, 100 m), if the travel road section cannot be identified by the map matching of the travel road identifying unit 21a, the vehicle C is newly established. Determine that you are driving on the road.
- a predetermined distance for example, 100 m
- step S145: N the control unit 20 uses the function of the exclusion unit 21c to start the support point management process (step S100).
- “passing” is recorded as a travel log in the learning information about the support point Q through which the vehicle C has passed, and the system waits until the vehicle C travels the support point Q next time. In this case, the new road flag corresponding to “pass” as the travel log remains set to OFF as the initial state.
- step S145: Y the control unit 20 uses the function of the exclusion unit 21c to determine the support point Q for which deceleration has not been performed.
- the new road flag of the travel log is set to ON (step S150).
- the control unit 20 determines whether or not traveling on the new road following the support point Q has continued two or more times without decelerating at the support point Q (Ste S155). Specifically, the control unit 20 excludes the support point Q from the deceleration support target when the new road flag in the latest travel log is ON and the new road flag in the previous travel log is ON. To do.
- step S155: N If it is not determined that driving on the new road following the support point Q without decelerating at the support point Q has been continued twice or more (step S155: N), the control unit 20 performs support point management. Return to the beginning of the process (step S100). That is, “passing” is recorded as a travel log in the learning information about the support point Q through which the vehicle C has passed, the new road flag for the “passing” is set to ON, and then the vehicle C Wait until you drive Q.
- step S140 the control unit 20 performs step S140. Execute. That is, if it continues two or more times on the new road following the support point Q without decelerating at the support point Q, the deceleration does not occur regardless of whether or not the deceleration probability is less than the exclusion threshold.
- the target flag for the support point Q that was not performed is set to OFF. In other words, if it continues two or more times on the new road following the support point Q without decelerating at the support point Q, it will be early without waiting for the deceleration probability to be less than the exclusion threshold.
- the target flag for the support point Q is set to OFF. Thereby, as shown in FIG. 2C, the support point Q where the new road section R 4 is newly established can be excluded from the object of the deceleration support at an early stage, and unnecessary deceleration support can be prevented from being implemented.
- the control unit 20 excludes the support point Q from the target of deceleration support. Also good. In this case, the support point Q at which the new road section R 4 is newly established can be excluded from the target for deceleration support earlier than in the embodiment.
- the control unit 20 determines whether to exclude the support point Q from the target of driving support. An operation for designating may be accepted.
- control unit 20 does not necessarily have to determine whether or not the vehicle C is traveling on the new road based on the map matching result. For example, when the navigation terminal 10 receives update data of the map information 30a from a server on the network, the control unit 20 may associate the reception date with each link data included in the update data. Then, the control unit 20 does not decelerate at the support point Q. If the reception date and time of the link data corresponding to the road section on which the vehicle C travels following the support point Q is within a predetermined period from the present, You may exclude the point Q from the object of deceleration assistance.
- the control unit 20 does not decelerate the vehicle C at the support point Q, and the number of times that the vehicle C has traveled on the new road section R 4 following the support point Q is equal to or greater than a threshold value (two times).
- the threshold value may be set according to the operation of the driver.
- the support point Q is excluded from the deceleration support target by setting the target flag to OFF, but the control unit 20 decelerates the support point Q by deleting the learning information about the support point Q. You may exclude from support object.
- the support point management process does not necessarily have to be executed in the navigation terminal 10 mounted on the vehicle C.
- the support point management process is executed in a server that acquires information indicating a travel route or a decelerated point from the vehicle C. May be.
- the support point acquisition unit may acquire a support point registered as a deceleration support target, and may acquire a support point that is effectively registered as a deceleration support target from a recording medium or a communication medium.
- the support point is a point where deceleration support is performed, and the point where deceleration support is performed may be a point where deceleration support is started or a point where deceleration support ends.
- the support point may be a point learned based on the deceleration history of the vehicle. This is because even if the support point is learned based on the deceleration history, the driving route of the driver can change due to the new construction of the new road.
- the support point may be a restriction point (a temporary stop point, a railroad crossing, etc.) on the map that needs to be decelerated. This is because even if a restriction point has been set in the past, the restriction point can be abolished along with the establishment of a new road.
- a restriction point a temporary stop point, a railroad crossing, etc.
- the exclusion means may exclude the support point from the object of the deceleration support when the vehicle travels on the new road following the support point without decelerating at the support point.
- the exclusion means identifies the road on which the vehicle is traveling at the stage where the vehicle has traveled a predetermined distance after passing through the support point, or after the predetermined period has elapsed, and if the road is a new road, It may be determined that the vehicle has traveled on a new road.
- the exclusion means obtains the vehicle speed at a stage where the vehicle has traveled a predetermined distance after passing through the support point or a stage where a predetermined period has elapsed, and travels on a road (new road) if the vehicle speed is equal to or less than a threshold value. It may be determined that it is not. This can prevent erroneous determination that the vehicle is traveling on the new road when the vehicle enters the facility after passing through the support point.
- the exclusion means is used when the traveling direction of the vehicle at the stage where the vehicle has traveled a predetermined distance after passing through the support point or after a predetermined period has deviated by more than a predetermined reference from the direction of the road where the support point exists.
- the support point may not be excluded from the deceleration support target.
- the deceleration support may be to generate a braking force in the braking portion of the vehicle regardless of the driver's operation, or to guide the driver to the deceleration timing.
- To exclude a support point from the target of deceleration support may be to delete the support point from the database in which the support point is registered, or not to delete the support point but to flag it as a target for deceleration support May be set.
- the exclusion means may determine that the road that has traveled following the support point is a road that has been defined as a new road in the map information, and has traveled on the new road following the support point. For example, when the time when a new road is established is recorded in the map information or when the data corresponding to the new road is recorded in the map information, the road on which the vehicle is running is the new road. It can be determined whether or not.
- the vehicle further includes a traveling road identifying unit that identifies a traveling road on which the vehicle is traveling based on the traveling locus of the vehicle and the map information, and the excluding unit includes a new road when the traveling road cannot be identified. It may be determined that the vehicle is running. In addition, when the traveling road cannot be specified, the information on the road on which the vehicle is traveling is not yet recorded in the map information, and the vehicle is traveling on a newly constructed road after the creation of the map information. Can be judged. In this configuration, it is possible to determine that the vehicle is traveling on the new road without waiting for the provision of map information recording information on the new road.
- the traveling road specifying means may specify a road having a shape that matches the traveling locus of the vehicle as a traveling road by known map matching.
- the exclusion means may exclude the support point from the object of the deceleration support when the vehicle has not decelerated at the support point and the number of times the vehicle has traveled on the new road following the support point exceeds a threshold value. Good.
- the support point is excluded from the target of deceleration support. Can be prevented. For example, when a vehicle enters a facility near the support point without decelerating at the support point, it is possible to prevent the support point from being excluded from the target of deceleration support.
- the method for managing support points can be applied as a program or method.
- the system, 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, and include various aspects. It is a waste.
- some changes may be made as appropriate, such as a part of software and a part of hardware.
- the invention is also established as a recording medium for a program for controlling the apparatus.
- 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.

(3)他の実施形態:
本発明の支援地点管理システムは、車両Cに搭載されたナビゲーション端末10によって実現されている。ナビゲーション端末10は、CPU,RAM,ROM等を備える制御部20と記録媒体30とを備える。制御部20は、記録媒体30やROMに記憶されたプログラムを実行する。本実施形態において制御部20は、このプログラムの一つとして支援地点管理プログラム21を実行する。
次に、支援地点管理処理について説明する。支援地点管理処理は、所定の時間周期または走行距離周期ごとに実行される処理である。なお、支援地点管理処理を実行する期間において、走行道路特定部21aの機能により制御部20は、所定の時間周期または走行距離周期ごとに車両Cが走行している走行道路区間を特定している。まず、支援地点取得部21bの機能により制御部20は、学習情報DB30bの各学習情報から支援地点Qを取得し、車両Cの周辺に支援地点Qが存在するか否かを判定する(ステップS100)。車両Cの周辺とは、公知の経路探索手法によって予め探索された走行予定経路上における車両Cの周辺を意味する。走行予定経路上における車両Cの周辺とは、走行予定経路上における現在位置から前方300m以内かつ当該現在位置から後方30m以内の範囲を意味する。本実施形態において、走行予定経路上の走行道路区間を車両Cが走行していることとする。
支援地点Qにて減速することなく、当該支援地点Qに続いて新設道路を走行することが1回でも生じた場合に、制御部20は、当該支援地点Qを減速支援の対象から除外してもよい。この場合、前記実施形態よりも早期に、新設道路区間R4が新設された支援地点Qを減速支援の対象から除外できる。なお、車両Cが支援地点Qにて減速することなく、当該支援地点Qに続いて新設道路区間R4を走行した場合、制御部20は、支援地点Qを運転支援の対象から除外するか否かを指定する操作を受け付けてもよい。
