Description

本発明は割込車両判定装置に関し、特に、自車両の周辺に存在する他車両が割込車両であるか否かを判定する割込車両判定装置に関するものである。   The present invention relates to an interrupting vehicle determination device, and more particularly to an interrupting vehicle determination device that determines whether or not another vehicle existing around the host vehicle is an interrupting vehicle.

車両の走行支援装置の1つとして、自車両の周辺に存在する他車両を検出し、当該他車両の中から自車両が走行する車線に割り込んでくる割込車両を判定して、所定の警報の報知及び走行制御を行う割込車両判定装置が実用化されている。例えば、特許文献1には、他車両を追跡して走行軌跡を推定し、その走行軌跡が所定の割込車両特有の特徴を有するときに、当該他車両を割込車両であると判定する技術が記載されている。
特開2003−281700号公報
As one of the vehicle travel support devices, another vehicle existing around the host vehicle is detected, and an interrupted vehicle that enters the lane in which the host vehicle travels is determined from the other vehicle, and a predetermined alarm is issued. An interrupting vehicle determination device that performs this notification and travel control has been put into practical use. For example, Patent Document 1 discloses a technique for estimating a travel locus by tracking another vehicle, and determining that the other vehicle is an interrupt vehicle when the travel locus has characteristics specific to a predetermined interrupt vehicle. Is described.
JP 2003-281700 A

しかしながら、上記の技術では、他車両の走行軌跡の推定が安定しない場合は、割込車両ではない車両を割込車両として誤判定してしまう問題がある。すなわち、現在の他車両を検出する技術においては、自車両の近傍に存在する他車両が、自車に接近しようとしているのか、自車から離れようとしているのかを判定する精度は必ずしも高くはない。そのため、先行車両の動きや自車両の動きによっては、自車両の近傍に存在しているだけの他車両を割込車両と誤判定してしまい、誤制御又は誤警報を行ってしまう場合がある。   However, in the above technique, there is a problem that a vehicle that is not an interrupted vehicle is erroneously determined as an interrupted vehicle when the estimation of the travel locus of the other vehicle is not stable. That is, in the current technology for detecting other vehicles, the accuracy of determining whether another vehicle existing in the vicinity of the own vehicle is approaching or leaving the own vehicle is not necessarily high. . Therefore, depending on the movement of the preceding vehicle and the movement of the own vehicle, other vehicles that exist only in the vicinity of the own vehicle may be erroneously determined as interrupted vehicles, and erroneous control or false alarms may be performed. .

本発明は、かかる事情に鑑みてなされたものであり、その目的は、誤判定をより減少させた割込車両判定装置を提供することにある。   This invention is made | formed in view of this situation, The objective is to provide the interruption vehicle determination apparatus which reduced the misjudgment more.

本発明は、自車両の走行状況を取得する自車両状況取得手段と、他車両状況取得手段によって取得された他車両の走行状況と自車両状況取得手段によって取得された自車両の走行状況とに基づき、他車両が割込車両であるか否かを判定する割込判定手段と、を備え、割込判定手段は、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満たさないときは、他車両が割込車両である可能性が第1閾値以上のときに、他車両を割込車両であると判定し、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満すときは、他車両が割込車両である可能性が第1閾値より高い第2閾値以上のときに、他車両を割込車両であると判定する割込車両判定装置である。   The present invention relates to a host vehicle status acquisition unit that acquires the driving status of the host vehicle, a driving status of the other vehicle acquired by the other vehicle status acquisition unit, and a driving status of the host vehicle acquired by the host vehicle status acquisition unit. And determining whether or not the other vehicle is an interrupted vehicle, wherein the interrupt determining unit determines whether one of the traveling status of the other vehicle and the traveling status of the own vehicle satisfies a predetermined condition. If not satisfied, when the possibility that the other vehicle is an interrupted vehicle is greater than or equal to the first threshold, it is determined that the other vehicle is an interrupted vehicle, and one of the traveling status of the other vehicle and the traveling status of the host vehicle When the vehicle satisfies a predetermined condition, an interruption vehicle determination device that determines that the other vehicle is an interruption vehicle when the possibility that the other vehicle is an interruption vehicle is equal to or higher than a second threshold that is higher than the first threshold. It is.

この構成によれば、割込判定手段は、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満たしているか否かにより、他車両を割込車両であると判定する閾値を第1閾値より高い第2閾値に変更する。そのため、常に一定の条件で割込車両であるか否かの判定を行う場合と比較して、誤判定のおそれを減少させることができる。   According to this configuration, the interrupt determination means determines whether the other vehicle is an interrupted vehicle based on whether one of the traveling status of the other vehicle and the traveling status of the host vehicle satisfies a predetermined condition. Is changed to a second threshold value higher than the first threshold value. Therefore, the risk of erroneous determination can be reduced as compared with the case where it is always determined whether or not the vehicle is an interrupted vehicle under certain conditions.

この場合、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満すときとは、他車両のうち自車両が走行する車線を先行して走行する先行車両が変わったときとすることができる。   In this case, when one of the traveling conditions of the other vehicle and the traveling condition of the host vehicle satisfies a predetermined condition, the preceding vehicle that travels ahead of the lane in which the host vehicle travels changes among other vehicles. It can be.

先行車両が変わったとき、すなわち、それまでの先行車両が先行車両でなくなるときは、先行車両ではなくなった他車両の位置が自車両近傍であり、かつ走行軌跡が自車両と重複しやすいため、当該他車両を割込車両と誤判定しやすいが、このような場合に、割込車両である可能性が第1閾値より高い第2閾値以上のときに当該他車両を割込車両であると判定することにより、誤判定のおそれを減少させることができる。   When the preceding vehicle changes, that is, when the preceding preceding vehicle is no longer the preceding vehicle, the position of the other vehicle that is no longer the preceding vehicle is in the vicinity of the own vehicle, and the traveling locus is likely to overlap with the own vehicle. Although it is easy to mistakenly judge the other vehicle as an interrupted vehicle, in such a case, when the possibility that the other vehicle is an interrupted vehicle is equal to or higher than a second threshold higher than the first threshold, By determining, the possibility of erroneous determination can be reduced.

この場合、先行車両が変わったときとは、先行車両の車線変更および自車両の車線変更のいずれかによって先行車両が変わったときとすることができる。   In this case, the time when the preceding vehicle has changed can be the time when the preceding vehicle has changed due to either the lane change of the preceding vehicle or the lane change of the host vehicle.

先行車両の車線変更および自車両の車線変更のいずれかによって先行車両が変わったときは、先行車両ではなくなった他車両の位置が自車両近傍であり、かつ走行軌跡が自車両と重複しやすいために当該他車両を割込車両と誤判定しやすいが、他車両を割込車両であると判定する閾値を第1閾値より高い第2閾値に変更することにより、誤判定のおそれを減少させることができる。   When the preceding vehicle changes due to either the lane change of the preceding vehicle or the lane change of the own vehicle, the position of the other vehicle that is no longer the preceding vehicle is in the vicinity of the own vehicle, and the traveling locus is likely to overlap with the own vehicle. Although it is easy to erroneously determine the other vehicle as an interrupted vehicle, the risk of erroneous determination is reduced by changing the threshold value for determining the other vehicle as an interrupted vehicle to a second threshold value that is higher than the first threshold value. Can do.

一方、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満すときとは、自車両が所定の旋回半径以下で旋回しているときであるものとすることができる。   On the other hand, the time when one of the traveling conditions of the other vehicle and the traveling condition of the host vehicle satisfies a predetermined condition may be a time when the host vehicle is turning at a predetermined turning radius or less.

自車両が所定の旋回半径以下の小さい旋回半径で旋回しているときは、自車両近傍の他車両が割込車両である可能性は低いため、割込車両である可能性が第1閾値より高い第2閾値以上のときに当該他車両を割込車両であると判定することにより、誤判定のおそれを減少させることができる。   When the host vehicle is turning with a small turning radius equal to or less than the predetermined turning radius, the possibility that the other vehicle in the vicinity of the host vehicle is an interrupting vehicle is low. By determining that the other vehicle is an interrupted vehicle when it is equal to or higher than the high second threshold, the risk of erroneous determination can be reduced.

あるいは、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満すときとは、自車両と他車両との相対速度が所定の相対速度以上であるときであるものとすることができる。   Alternatively, when any of the traveling conditions of the other vehicle and the traveling condition of the host vehicle satisfies a predetermined condition, the relative speed between the host vehicle and the other vehicle is equal to or higher than a predetermined relative speed. be able to.

自車両と他車両との相対速度が所定の相対速度以上と大きいときは、自車両近傍の他車両が割込車両である可能性は低いため、割込車両である可能性が第1閾値より高い第2閾値以上のときに当該他車両を割込車両であると判定することにより、誤判定のおそれを減少させることができる。   When the relative speed between the host vehicle and the other vehicle is greater than a predetermined relative speed, the possibility that the other vehicle in the vicinity of the host vehicle is an interrupted vehicle is low. By determining that the other vehicle is an interrupted vehicle when it is equal to or higher than the high second threshold, the risk of erroneous determination can be reduced.

一方、本発明においては、自車両の運転者の運転状態を取得する運転状態取得手段をさらに備え、割込判定手段は、運転状態取得手段によって検出された運転者の運転状態が所定の条件を満たすときは、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満すときであっても、他車両が割込車両である可能性が第1閾値以上のときに、他車両を割込車両であると判定することが好適である。   On the other hand, in the present invention, it further comprises driving state acquisition means for acquiring the driving state of the driver of the host vehicle, and the interrupt determination means is configured such that the driving state of the driver detected by the driving state acquisition means satisfies a predetermined condition. When satisfying, even if any of the traveling status of the other vehicle and the traveling status of the host vehicle satisfy a predetermined condition, the possibility that the other vehicle is an interrupted vehicle is greater than or equal to the first threshold, It is preferable to determine that the other vehicle is an interrupted vehicle.

この構成によれば、割込判定手段は、運転状態取得手段によって検出された運転者の運転状態が所定の条件を満たすときは、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満すときであっても、他車両が割込車両である可能性が第1閾値以上のときに、他車両を割込車両であると判定する。そのため、運転者の運転状態によっては割込車両の判定に用いる閾値に低い方の第1閾値を適用し、割込車両を判定できない可能性を減少させて、安全性を担保することができる。   According to this configuration, when the driving state of the driver detected by the driving state acquisition unit satisfies a predetermined condition, the interrupt determination unit determines whether the traveling state of the other vehicle or the traveling state of the host vehicle is predetermined. Even when the above condition is satisfied, it is determined that the other vehicle is an interrupted vehicle when the possibility that the other vehicle is an interrupted vehicle is greater than or equal to the first threshold value. Therefore, depending on the driving state of the driver, the lower first threshold value is applied to the threshold value used for determination of the interrupted vehicle, and the possibility that the interrupted vehicle cannot be determined is reduced, thereby ensuring safety.

本発明の割込車両判定装置によれば、誤判定をより減少させることができる。   According to the interrupting vehicle determination device of the present invention, erroneous determination can be further reduced.

The face orientation sensor 17 is for detecting the direction in which the driver's face during driving is facing, and functions as driving state acquisition means described in the claims. The detected signal is output to the preceding vehicle selection unit 20 and the interrupted vehicle determination unit 30. In addition, as a driving | running state acquisition means, you may provide the sensor which detects a driver | operator's dozing.

先行車選択部20は、演算を行うマイクロプロセッサ、マイクロプロセッサに各処理を実行させるためのプログラム等を記憶するROM、演算結果などの各種データを記憶するRAM及び12Vバッテリによってその記憶内容が保持されるバックアップRAM等により構成されている。先行車選択部20は、アクセルペダル12からのスロットル量、車速センサ13からの車速信号、ヨーレートセンサ14からのヨーレート信号、操舵角センサ15からの操舵角信号及びウィンカーSW16からのウィンカー表示などに基づいて求められる自車両の走行状態から自車両の進路を推定するとともに、この推定結果と他車両の位置とを比較し、他車両が自車両の進路前方に存在すると判断された場合に、この他車両を先行車両として認識する。また、先行車選択部20は、このような先行車両の認識をフレーム毎に行うことによって、先行車両が前フレームの時と入れ替わったか否かも判定する。先行車選択部20によって認識された先行車に関する情報は、割込車両判断部30に出力される。なお、自車両の進路を推定する際に、ステレオカメラ11で検出された白線情報などを用いてもよい。   The preceding vehicle selection unit 20 is stored in memory by a microprocessor that performs calculations, a ROM that stores programs for causing the microprocessor to execute each process, a RAM that stores various data such as calculation results, and a 12V battery. A backup RAM or the like. The preceding vehicle selection unit 20 is based on the throttle amount from the accelerator pedal 12, the vehicle speed signal from the vehicle speed sensor 13, the yaw rate signal from the yaw rate sensor 14, the steering angle signal from the steering angle sensor 15, the winker display from the winker SW 16, and the like. The path of the host vehicle is estimated from the travel state of the host vehicle, and the estimated result is compared with the position of the other vehicle.If it is determined that the other vehicle is ahead of the path of the host vehicle, Recognize the vehicle as a preceding vehicle. The preceding vehicle selection unit 20 also determines whether or not the preceding vehicle has been replaced with the previous frame by recognizing the preceding vehicle for each frame. Information regarding the preceding vehicle recognized by the preceding vehicle selection unit 20 is output to the interrupt vehicle determination unit 30. Note that white line information detected by the stereo camera 11 may be used when estimating the course of the host vehicle.

割込車両判断部30も、演算を行うマイクロプロセッサ、マイクロプロセッサに各処理を実行させるためのプログラム等を記憶するROM、演算結果などの各種データを記憶するRAM及び12Vバッテリによってその記憶内容が保持されるバックアップRAM等により構成されている。割込車両判断部30は、ミリ波センサ10及びステレオカメラ11によって取得された他車両の走行状況と、アクセルペダル12、車速センサ13等によって取得された自車両の走行状況と、先行車選択部20からの先行車に関する情報とに基づき、他車両が割込車両であるか否かを判定するためのものであり、特許請求の範囲に記載の割込判定手段として機能する。   The interrupted vehicle determination unit 30 also holds the stored contents by a microprocessor that performs calculations, a ROM that stores programs for causing the microprocessor to execute each process, a RAM that stores various data such as calculation results, and a 12V battery. The backup RAM etc. are comprised. The interrupting vehicle determination unit 30 includes a traveling state of another vehicle acquired by the millimeter wave sensor 10 and the stereo camera 11, a traveling state of the host vehicle acquired by the accelerator pedal 12, the vehicle speed sensor 13, and the like, and a preceding vehicle selection unit. This is for determining whether or not the other vehicle is an interrupted vehicle based on the information on the preceding vehicle from No. 20, and functions as an interrupt determining means described in the claims.

割込車両判断部30は、他車両が割込車両であるか否かを判定する基準となる閾値として、少なくとも2通りの閾値を有しており、他車両の走行状況及び自車両の走行状況のいずれかが後述する所定の条件を満たさないときは、誤判定をしにくい状況にあるものとして、判定基準としてより緩やかな基準となる低い閾値を用いて割込車両であるか否かの判定を行う。一方、他車両の走行状況及び自車両の走行状況のいずれかが後述する所定の条件を満たす場合は、誤判定をしやすい状況にあるか、割込車両が存在する可能性が低い状況にあるものとして、判定基準としてより厳しい基準となる高い閾値を用いて割込車両であるか否かの判定を行う。あるいは、割込車両の判定を行う間隔を通常より長くするか、割込車両の判定を完全に中止するようにしても良い。割込車両を判定する基準となる閾値としては、例えば、他車両の自車両に対する横位置、距離、横方向速度等を用いることができる。   The interrupting vehicle determination unit 30 has at least two threshold values as thresholds for determining whether or not the other vehicle is an interrupting vehicle, and the traveling status of the other vehicle and the traveling status of the host vehicle. If any of the above does not satisfy a predetermined condition described later, it is difficult to make a misjudgment, and it is determined whether or not the vehicle is an interrupted vehicle by using a lower threshold that is a more gradual criterion as a criterion. I do. On the other hand, if one of the traveling conditions of the other vehicle and the traveling condition of the host vehicle satisfies a predetermined condition to be described later, it is likely that an erroneous determination is likely to occur, or that there is a low possibility that an interrupting vehicle exists. As a thing, it is determined whether or not the vehicle is an interrupted vehicle by using a high threshold value that is a stricter criterion. Alternatively, the interval for determining the interrupted vehicle may be set longer than usual, or the determination of the interrupted vehicle may be completely stopped. As a threshold value serving as a reference for determining an interrupted vehicle, for example, a lateral position, a distance, a lateral speed, and the like of another vehicle with respect to the host vehicle can be used.

さらに、割込車両判断部30は、顔向きセンサ17からの信号が、運転者の運転状態が適切でないことを示しているときは、他車両の走行状況及び自車両の走行状況のいずれかが後述する所定の条件を満たす場合であり、誤判定をしやすい状況にあるか、割込車両が存在する可能性が低い状況にある場合であっても、判定基準としてより緩やかな基準となる低い閾値を用いて割込車両と判定しやすくし、安全を担保する。   Furthermore, when the signal from the face direction sensor 17 indicates that the driving state of the driver is not appropriate, the interrupting vehicle determination unit 30 determines whether the driving state of the other vehicle or the driving state of the own vehicle is This is a case where a predetermined condition that will be described later is satisfied, and even if it is in a situation where it is easy to make a misjudgment or in a situation where there is a low possibility that an interrupting vehicle exists, a low standard that is a gradual criterion Using a threshold value, it is easy to determine that the vehicle is an interrupted vehicle and ensures safety.

It is composed of a backup RAM or the like. Note that the preceding vehicle selection unit 20, the interrupted vehicle determination unit 30, and the travel control unit 40 may be configured to be integrated in hardware or partially shared. The travel control unit 40 includes a buzzer 51 for notifying the driver of a predetermined alarm, a display 52 for displaying a predetermined display for the driver, a throttle control 53 for controlling the amount of air supplied to the engine, and each wheel.

By controlling the throttle control 53, the brake control 54, and the like, the driving force and braking force applied to the vehicle are adjusted, and constant speed control, follow-up control, and slow acceleration / slow deceleration control are executed.

次に、図2を参照して、ACCシステム1の動作について説明する。図2は、ACCシステム1による走行支援制御の処理手順を示すフローチャートである。この制御は、車両の電源がオンにされてからオフにされるまでの間、先行車選択部20、割込車両判断部30及び走行制御ユニット40によって所定のタイミングで繰り返し実行される。   Next, the operation of the ACC system 1 will be described with reference to FIG. FIG. 2 is a flowchart showing a processing procedure of driving support control by the ACC system 1. This control is repeatedly executed at a predetermined timing by the preceding vehicle selection unit 20, the interrupted vehicle determination unit 30, and the travel control unit 40 from when the vehicle power is turned on to when it is turned off.

ステップS100では、ミリ波センサ10から、受信波の電波強度、他車両の有無、他車両と自車両との距離、相対速度および自車両からの横変位などのパラメータが読み込まれる。同様に、ステレオカメラ11から、他車両の有無、他車両と自車両との距離、相対速度および自車両からの横変位などのパラメータが読み込まれる。   In step S100, parameters such as the radio wave intensity of the received wave, the presence / absence of another vehicle, the distance between the other vehicle and the host vehicle, the relative speed, and the lateral displacement from the host vehicle are read from the millimeter wave sensor 10. Similarly, parameters such as the presence / absence of another vehicle, the distance between the other vehicle and the host vehicle, the relative speed, and the lateral displacement from the host vehicle are read from the stereo camera 11.

続くステップS102では、先行車選択部20が、ステップS100で読み込まれたミリ波センサ10およびステレオカメラ11それぞれの検出結果を融合(フュージョン)して他車両の走行状況と取得するとともに、アクセルペダル12、車速センサ13等に基づいて求められる自車両の走行状態から自車両の進路を推定し、この推定結果と他車両の位置とを比較し、他車両が自車両の進路前方に存在すると判断された場合に、この他車両を先行車両として認識する。   In the subsequent step S102, the preceding vehicle selection unit 20 fuses the detection results of the millimeter wave sensor 10 and the stereo camera 11 read in step S100 to acquire the traveling state of the other vehicle, and the accelerator pedal 12 Then, the course of the host vehicle is estimated from the traveling state of the host vehicle obtained based on the vehicle speed sensor 13 and the like, the result of the estimation is compared with the position of the other vehicle, and it is determined that the other vehicle is present ahead of the course of the host vehicle. If this happens, the other vehicle is recognized as a preceding vehicle.

ステップS104では、先行車選択部20が、ステップS102で認識した先行車両が前フレーム時と入れ替わったか否かを判定する。もし、先行車両が入れ替わっていれば、次のステップS106に進む。もし、先行車両が入れ替わっていなければ、ステップS108に進む。   In step S104, the preceding vehicle selection unit 20 determines whether the preceding vehicle recognized in step S102 has been replaced with that in the previous frame. If the preceding vehicle has been changed, the process proceeds to the next step S106. If the preceding vehicle has not been replaced, the process proceeds to step S108.

先行車両が入れ替わる場合とは、例えば、図3に示すように、自車両100に対して、それまで先行車両であった他車両200が車線変更し、先々行車であった他車両300が先行車両となる場合である。また先行車両が入れ替わる場合とは、図4に示すように、自車両100が車線変更を行うことにより、それまで先行車両であった他車両200が先行車両ではなくなり、変更先の車線を走行していた他車両300が新たに先行車両となる場合である。いずれの場合も、それまで先行車両であった他車両200を割込車両であると誤判定しやすいため、この場合は割込車両判定の閾値を高くする処理を行う。なお、本実施形態においては、厳密に先行車両の入替わりを判定しなくとも、ステレオカメラ11の撮像画像における先行車両のウィンカー等を判定することにより、割込車両判定の閾値を高くする処理をするか否かを決定しても良い。   For example, as shown in FIG. 3, when the preceding vehicle is switched, the other vehicle 200 that has been the preceding vehicle has changed lanes with respect to the own vehicle 100, and the other vehicle 300 that has been the preceding vehicle is the preceding vehicle. This is the case. In addition, when the preceding vehicle is switched, as shown in FIG. 4, when the own vehicle 100 changes lanes, the other vehicle 200 that has been the preceding vehicle is no longer the preceding vehicle and travels in the lane of the change destination. This is a case where the other vehicle 300 that has been used becomes a preceding vehicle. In any case, since it is easy to erroneously determine that the other vehicle 200 that has been the preceding vehicle is an interrupted vehicle, processing for increasing the threshold for determining the interrupted vehicle is performed in this case. In the present embodiment, the process of increasing the threshold for determining the interrupted vehicle by determining the blinker of the preceding vehicle in the captured image of the stereo camera 11 without strictly determining the replacement of the preceding vehicle. You may decide whether to do it.

ステップS106では、先行車選択部20が、新しい先行車両と自車両との距離が、前フレームにおける先行車両と自車両との距離+αより大きいか否かを判定する。もし、新しい先行車両と自車両との距離が、前フレームにおける先行車両と自車両との距離+αより大きい場合は、図3あるいは図4に示す状況に該当する可能性が高いため、誤判定を避けるためにステップS110に進む。   In step S106, the preceding vehicle selection unit 20 determines whether or not the distance between the new preceding vehicle and the host vehicle is greater than the distance + α between the preceding vehicle and the host vehicle in the previous frame. If the distance between the new preceding vehicle and the host vehicle is greater than the distance between the preceding vehicle and the host vehicle in the previous frame + α, there is a high possibility that the situation shown in FIG. To avoid this, go to step S110.

ステップS107では、割込車両判断部30が、自車両が所定の旋回半径以下で旋回しているか、あるいは他車両と自車両との相対速度が所定の相対速度以上であるかを判定する。判定に用いる所定の旋回半径は、比較的小さな旋回半径とすればよく、例えば所定の旋回半径を30mとすればよい。比較的に急なカーブを走行中である場合には、自車両近傍の他車両が割込車両である可能性は低いため、誤判定を避けるためにステップS110に進む。また、判定に用いる所定の相対速度には、比較的大きな相対速度を設定すればよく、例えば所定の相対速度を40km/hとすればよい。比較的に大きな相対速度で走行中の場合には、自車両近傍の他車両が割込車両である可能性は低いため、誤判定を避けるためにステップS110に進む。   In step S107, the interrupting vehicle determination unit 30 determines whether the host vehicle is turning at a predetermined turning radius or less, or whether the relative speed between the other vehicle and the host vehicle is equal to or higher than a predetermined relative speed. The predetermined turning radius used for the determination may be a relatively small turning radius, for example, the predetermined turning radius may be 30 m. If the vehicle is traveling on a relatively steep curve, it is unlikely that another vehicle in the vicinity of the host vehicle is an interrupted vehicle, so the process proceeds to step S110 to avoid erroneous determination. In addition, a relatively large relative speed may be set as the predetermined relative speed used for the determination. For example, the predetermined relative speed may be set to 40 km / h. If the vehicle is traveling at a relatively high relative speed, there is a low possibility that another vehicle in the vicinity of the host vehicle is an interrupted vehicle, and thus the process proceeds to step S110 to avoid erroneous determination.

一方、ステップS104において先行車両が入れ替わっていない場合や、ステップS107において、旋回半径30m以下か相対速度が40km/h以上でない場合であっても、ステップS108において、アクセルペダル12あるいはウィンカーSW16がONである場合には、自車両が車線変更を行っており、近隣の他車両を割込車両として誤判定しやすいため、割込車両判定の閾値を高くする処理をするために、ステップS110に進む。もし、アクセルペダル12あるいはウィンカーSW16がOFFである場合には、割込車両判定の閾値を変更しないようにステップS114に進む。なお、自車両のアクセルペダル12あるいはウィンカーSW16だけではなく、ヨーレイトセンサ14や操舵角センサ15からの情報や、ステレオカメラ11からの道路上の白線情報から自車が車線変更を行っていると判定しても良い。   On the other hand, even if the preceding vehicle has not been replaced in step S104, or even if the turning radius is not more than 30 m or the relative speed is not more than 40 km / h in step S107, the accelerator pedal 12 or the blinker SW16 is ON in step S108. In some cases, the host vehicle has changed lanes, and it is easy to make a misjudgment as another nearby vehicle as an interrupted vehicle. Therefore, the process proceeds to step S110 in order to increase the threshold for determining the interrupted vehicle. If the accelerator pedal 12 or the blinker SW 16 is OFF, the process proceeds to step S114 so as not to change the interrupt vehicle determination threshold. Note that it is determined that the vehicle is changing lanes not only from the accelerator pedal 12 or the winker SW 16 of the host vehicle but also from information from the yaw rate sensor 14 and the steering angle sensor 15 and white line information on the road from the stereo camera 11. You may do it.

ステップS110では、顔向きセンサ17によって運転者の顔向きを検出し、運転者の顔向きが自車両の正面方向か、あるいは割込判定の対象となる他車両の方向を向いている場合は、運転者が当該他車両に十分な注意を払っているものとして、ステップS112に進み、誤判定を避けるために割込車両判定の閾値を高くする処理をする。一方、運転者の顔向きが自車両の正面方向か、あるいは割込判定の対象となる他車両の方向を向いていない場合は、運転者が当該他車両に十分な注意を払っておらず、割込車両判定の閾値を高くすると危険な場合があるので、ステップS114に進み、割込車両判定の閾値を変更しないようにする。なお、この場合、運転者の居眠り等を検出し、運転者が居眠りをしている場合には、割込車両判定の閾値を変更しないようにしても良い。   In step S110, the driver's face direction is detected by the face direction sensor 17, and when the driver's face direction is the front direction of the own vehicle or the direction of another vehicle that is the target of the interrupt determination, Assuming that the driver is paying sufficient attention to the other vehicle, the process proceeds to step S112, and processing for increasing the threshold value of the interrupted vehicle determination is performed in order to avoid erroneous determination. On the other hand, if the driver's face direction is the front direction of the host vehicle or the direction of the other vehicle that is the target of the interrupt determination, the driver is not paying sufficient attention to the other vehicle, Since it may be dangerous to increase the threshold for determining the interrupted vehicle, the process proceeds to step S114 so that the threshold for determining the interrupted vehicle is not changed. In this case, the driver's doze may be detected, and the threshold for determining the interrupted vehicle may not be changed when the driver is dozing.

ステップS112では、割込車両判断部30が、当該他車両に対する割込判定の閾値を高く狭める処理を行う。具体的には、他車両と自車両との横位置等のパラメータを、より割込車両と判定しにくいように変更する。あるいは、割込車両の判定を行う間隔を通常より長くするか、割込車両判定を完全に中止する時間を一定時間設けるようにする。一方、ステップS114では、割込車両判断部30が、割込車両判定の閾値を変更せず、通常通りの他車両と自車両との横位置等のパラメータを割込車両判定の閾値とする。   In step S112, the interrupt vehicle determination unit 30 performs a process of narrowing the threshold for interrupt determination for the other vehicle to be high. Specifically, the parameters such as the lateral positions of the other vehicle and the host vehicle are changed so that it is more difficult to determine that the vehicle is an interrupted vehicle. Alternatively, the interval for determining the interrupted vehicle is made longer than usual, or a time for completely canceling the interrupted vehicle determination is set for a certain time. On the other hand, in step S114, the interrupted vehicle determination unit 30 does not change the threshold for determining the interrupted vehicle, and sets parameters such as the lateral positions of the other vehicle and the host vehicle as usual as the threshold for determining the interrupted vehicle.

ステップS116では、割込車両判断部30が、ステップS112あるいはステップS114で設定した閾値を用い、他車両が割込車両であるか否かの判定を行う。   In step S116, the interrupt vehicle determination unit 30 determines whether or not the other vehicle is an interrupt vehicle using the threshold set in step S112 or step S114.

本実施形態によれば、割込車両判断部30は、他車両の走行状況及び自車両の走行状況のいずれかが所定の条件を満たしているか否かにより、他車両を割込車両であると判定する閾値をより高い閾値に変更する。そのため、常に一定の条件で割込車両であるか否かの判定を行う場合と比較して、誤判定のおそれを減少させることができる。   According to the present embodiment, the interrupted vehicle determination unit 30 determines that the other vehicle is an interrupted vehicle depending on whether one of the traveling status of the other vehicle and the traveling status of the host vehicle satisfies a predetermined condition. The threshold value to be determined is changed to a higher threshold value. Therefore, the risk of erroneous determination can be reduced as compared with the case where it is always determined whether or not the vehicle is an interrupted vehicle under certain conditions.

割込車両判断部30は、先行車両が変わったとき、すなわち、それまでの先行車両が先行車両でなくなるときは、先行車両ではなくなった他車両の位置が自車両近傍であり、かつ走行軌跡が自車両と重複しやすいため、当該他車両を割込車両と誤判定しやすいが、本実施形態によれば、このような場合に、他車両を割込車両であると判定する閾値をより高い閾値に変更することにより、誤判定のおそれを減少させることができる。   When the preceding vehicle changes, that is, when the preceding preceding vehicle is no longer the preceding vehicle, the interrupting vehicle determination unit 30 determines that the position of the other vehicle that is no longer the preceding vehicle is in the vicinity of the host vehicle and the travel locus is Since it is easy to overlap with the own vehicle, it is easy to erroneously determine the other vehicle as an interrupted vehicle. However, according to the present embodiment, in such a case, the threshold for determining that the other vehicle is an interrupted vehicle is higher. By changing the threshold value, the risk of erroneous determination can be reduced.

先行車両が変わったときとは、具体的には図3に示すように、それまで先行車両であった他車両200が車線変更し、先々行車であった他車両300が先行車両となる場合であり、あるいは図4に示すように、自車両100が車線変更を行うことにより、それまで先行車両であった他車両200が先行車両ではなくなり、変更先の車線を走行していた他車両300が新たに先行車両となる場合である。割込車両判定は、他車両の横位置、距離、横方向速度等で判定することが多いが、相対的な車線変更の速度が遅いとき等には、横方向速度が正確に検出することができず、他車両が車線変更していくのか、自車両の走行車線に割り込んでくるのかが判別できず、誤って割込車両ではない他車両を割込車両と誤判定する場合がある。本実施形態では、このような場合に、割込車両判断部30が割込車両判定の閾値を高くする、あるいは割込車両の判定を行う間隔を通常より長くするか、割込車両判定を中止する時間を一定時間設けることにより、誤判定を低減することができる。   Specifically, when the preceding vehicle has changed, as shown in FIG. 3, the other vehicle 200 that has been the preceding vehicle changes lanes, and the other vehicle 300 that has been the preceding vehicle becomes the preceding vehicle. Yes, or as shown in FIG. 4, when the own vehicle 100 changes lanes, the other vehicle 200 that has been the preceding vehicle is no longer the preceding vehicle, and the other vehicle 300 that has traveled in the changed lane has changed. This is a case where it becomes a new preceding vehicle. Interruption vehicle determination is often based on the lateral position, distance, lateral speed, etc. of other vehicles, but when the relative lane change speed is slow, the lateral speed can be accurately detected. It is not possible to determine whether the other vehicle is changing lanes or whether it is interrupting the traveling lane of the own vehicle, and other vehicles that are not interrupted vehicles may be erroneously determined as interrupted vehicles. In this embodiment, in such a case, the interrupted vehicle determination unit 30 increases the threshold for determining the interrupted vehicle, or makes the interval for determining the interrupted vehicle longer than usual, or cancels the interrupted vehicle determination. It is possible to reduce misjudgment by providing a certain period of time.

また、本実施形態では、割込車両が存在する可能性が低い、自車両が旋回半径30m以下で旋回しているか、あるいは他車両と自車両との相対速度が40km/h以上である場合には、割込車両判断部30が割込車両判定の閾値を高くする等の処理を行うため、誤判定を低減することができる。   Further, in the present embodiment, when there is a low possibility that an interrupting vehicle exists, the own vehicle is turning with a turning radius of 30 m or less, or the relative speed between the other vehicle and the own vehicle is 40 km / h or more. Since the interrupted vehicle determination unit 30 performs processing such as increasing the threshold for determining the interrupted vehicle, erroneous determination can be reduced.

一方、もし、運転者が割込車両の方向あるいは前方に顔を向けていないときに、割込車両の判定をしないと危険な場合があり得る。そこで、本実施形態では、割込車両判断部30は、顔向きセンサ17によって検出された運転者の顔向きが正面方向か割込車両判定の対象となる他車両の方向に向いていない場合には、他の条件により割込車両判定の閾値を高くする等の処理を行う場合であっても、割込車両判定の閾値を変更しない。これにより、運転者の運転状態が適切でない場合において、割込車両を判定できない可能性を減少させて、安全性を担保することができる。   On the other hand, if the driver does not turn to the front of the interrupted vehicle or faces forward, it may be dangerous if the driver is not determined. Therefore, in the present embodiment, the interrupting vehicle determination unit 30 determines that the driver's face direction detected by the face direction sensor 17 is not in the front direction or the direction of another vehicle that is the target of the interrupting vehicle determination. Does not change the threshold for determining the interrupted vehicle even when processing such as increasing the threshold for determining the interrupted vehicle under other conditions is performed. Thereby, when a driver | operator's driving | running state is not appropriate, possibility that an interruption vehicle cannot be determined will be reduced and safety | security can be ensured.
