Definitions
- the present invention relates to driving support technology for a host vehicle such as collision avoidance.
- the traveling route of the subject vehicle after turning interferes with the traveling route of vehicles other than the subject vehicle, Depending on the timing of both, there is a risk of contact between vehicles. That is, before the turn with respect to the three-dimensional object, the vehicles other than the own vehicle were not present to prevent the progress of the own vehicle, but when the own vehicle turned, the vehicle prevented the progress of the own vehicle, or the own vehicle There is a possibility of hindering the progress of the vehicle.
- an object of the present invention is a system for assisting driving such as collision avoidance of a vehicle, and for turning control of the host vehicle for collision avoidance.
- An object of the present invention is to provide a system that can appropriately determine whether or not it is possible without complicated processing.
- the present invention provides a start and end point of turn control on an avoidance target trajectory for avoiding a collision with a three-dimensional object due to a turn of the host vehicle in a system that supports a collision avoidance of the vehicle.
- the vehicle driving support system recognizes a three-dimensional object existing in the traveling direction of the own vehicle, and when the existence of the three-dimensional object is recognized by the recognition unit, An acquisition unit that acquires an avoidance target trajectory for avoiding a collision between the three-dimensional object and the host vehicle based on a traveling state, and an assist control unit that controls turning of the host vehicle according to the avoidance target track acquired by the acquisition unit And the support based on the distance between the position of the host vehicle under the turn control and the position of the three-dimensional object in the turn control section on the avoidance target track where the turn control of the host vehicle is performed by the support control unit.
- a turning permission unit that permits execution of turning control of the host vehicle by the control unit.
- the avoidance target trajectory is acquired by the acquisition unit when the recognition unit recognizes the presence of the three-dimensional object in the traveling direction of the host vehicle.
- This avoidance target trajectory is a trajectory for vehicle travel that can be employed to avoid a three-dimensional object in which the vehicle is recognized, and is acquired based on the travel state of the host vehicle. Examples of the traveling state include vehicle speed and lateral acceleration of the host vehicle.
- the acquisition of the avoidance target trajectory no special conditions are imposed on the content of the control related to turning and braking of the own vehicle for realizing traveling on the trajectory.
- a target trajectory may be acquired.
- the assistance control unit performs assistance control for collision avoidance related to the turning of the host vehicle based on the avoidance target trajectory acquired as described above. Whether or not is actually executed is determined by the turning permission unit.
- the turning permission unit grasps the distance between the position of the host vehicle and the position of the three-dimensional object in the turning control section where the turning control is performed by the support control unit.
- the turn control section is a section in which the turn control is continued in order to avoid a collision of the host vehicle with the three-dimensional object.
- the distance between the position of the host vehicle and the position of the three-dimensional object on the avoidance target track in the turn control section guarantees a reasonable reason for the vehicle to naturally avoid a collision with the three-dimensional object.
- the turning permission unit gives permission to execute turning control based on the distance as described above, so that the turning of the host vehicle can be appropriately performed without installing a sensor or the like for detecting surrounding vehicles. It is possible to make a determination regarding control.
- the turning permission unit includes a predetermined control start point at which turning control of the host vehicle is started by the support control unit on the avoidance target track, and the avoidance target track.
- the distance between the position of the host vehicle under the turn control and the position of the three-dimensional object in the continuous turn control section between the predetermined control end point at which the turn control ends and the position of the three-dimensional object causes a collision with the three-dimensional object.
- execution of turning control of the host vehicle by the support control unit may be permitted.
- the turning permission unit determines the position of the host vehicle and the three-dimensional object in the turning control section defined from the predetermined control start point and the predetermined control end point on the avoidance target track. Know the distance between the location. Therefore, the reason why the distance between the host vehicle and the three-dimensional object in the turn control section is not more than the predetermined avoidance distance is a reasonable reason for the vehicle to naturally avoid a collision with the three-dimensional object. On the other hand, it means that there is no reasonable reason for approaching a vehicle that performs such turning control for a vehicle that exists around the host vehicle.
- the fact that the distance is equal to or less than the predetermined avoidance distance means that the host vehicle is inevitable to turn because the host vehicle is approaching a three-dimensional object.
- the host vehicle it is not rare that a vehicle that is still present around the host vehicle approaches the host vehicle that is turning control, and the running state of the vehicle is not preferable.
- the possibility of approaching the vehicle after turning is extremely low. Therefore, in such a case, it is reasonable to consider that the turning of the host vehicle can be permitted in order to avoid a collision with a three-dimensional object.
- the turning permission unit gives permission for turning control of the own vehicle, and the support control unit executes turning control so as to avoid the collision of the own vehicle.
- the predetermined avoidance distance is appropriately defined as a distance that can be recognized as having the above-described rational reason for the turning control of the host vehicle.
- the turning control of the own vehicle is permitted only when the distance between the three-dimensional object and the own vehicle in the turning control section is equal to or less than the predetermined avoidance distance. For this reason, when turning control is performed, the distance between the host vehicle and the three-dimensional object is secured, and emergency turning control is not required, or the surrounding vehicle is not present during the turning control because the three-dimensional object does not exist. When there is a possibility that the vehicle enters a region where the three-dimensional object does not exist, the turning control of the host vehicle is not performed. As a result of the permission determination regarding the turn control of the own vehicle in this way, it is possible to appropriately make a determination regarding the turn control of the own vehicle without installing a sensor or the like for detecting surrounding vehicles on the own vehicle. It becomes.
- the turn permission unit may be configured such that, in the entire range of the turn control section, the distance between the position of the host vehicle under the turn control and the position of the three-dimensional object is equal to or less than the predetermined avoidance distance. In this case, execution of turning control of the host vehicle by the support control unit may be permitted. By doing in this way, the space
- the support control unit may cause the host vehicle to travel according to the avoidance target track by performing braking control of the host vehicle in addition to the turning control.
- the avoidance target trajectory acquired by the acquisition unit is calculated on the assumption that the support control unit performs control related to turning of the host vehicle and control related to braking. Control related to turning and braking is performed so that the vehicle travels along the road. And even if it is time to perform the control regarding such turning and braking, the turning permission unit performs the determination regarding the permission of the turning control as described above as long as the turning control is performed. Note that when the turning permission is not permitted by the turning permission unit, the support control unit may perform only the braking control of the host vehicle.
- the predetermined control start point is a delay time required from when the turning permission unit permits execution of turning control of the own vehicle until the own vehicle actually starts turning. May be set based on the distance traveled by the host vehicle and the current position of the host vehicle. Mechanical and electrical processing time required in the driving support system of the vehicle is present as a delay time until the turning permission of the turning control is given by the turning permission unit and the vehicle is actually turned. Therefore, even if the host vehicle is actually permitted to control turning, the host vehicle will proceed according to the vehicle speed at that time due to the delay time. The turning control is started.
- the predetermined control start point at which the turning control is started is set based on the traveling distance of the own vehicle by the delay time and the current position of the own vehicle, so that the own vehicle and the three-dimensional object in the turning control section are set. It becomes possible to grasp the distance between the two more accurately.
- the predetermined control end point is the avoidance target trajectory, It may be set as a stop point at which the host vehicle stops when the turning control and the braking control of the host vehicle are performed by the support control unit.
- the predetermined control end point is set, when the own vehicle can avoid a collision with a three-dimensional object by turning and braking, the own vehicle that is in the stopped state or the own vehicle that is about to reach the stopped state There is a reasonable reason for the collision avoidance driving.
- the drive vehicle when the turn control of the drive vehicle is performed by the support control unit on the avoidance target track, the drive vehicle starts to be separated from the three-dimensional object. Or the position of the host vehicle at the time when the distance between the host vehicle and the three-dimensional object starts to become constant as a result of the turning control of the host vehicle being performed by the support control unit. May be. Even when the predetermined control end point is set in this way, as in the case described above, the vehicle can be regarded as having been able to avoid a collision with the three-dimensional object by turning, or the three-dimensional object described above. There is a reasonable reason for the turn in the turn control section that is specified based on the position of the host vehicle when the distance starts to become constant.
- the turning permission unit is configured to perform the turning control section in the turning control section. Regardless of the distance between the position of the host vehicle under turning control and the three-dimensional object, execution of turning control of the host vehicle by the support control unit may be permitted.
- the avoidance target trajectory is a trajectory in which the collision between the host vehicle and the previous three-dimensional object cannot be avoided
- the relative positional relationship between the host vehicle and the three-dimensional object is such that the collision with the three-dimensional object is avoided even if the host vehicle turns.
- a system for assisting driving such as collision avoidance of a vehicle which can appropriately determine whether or not the turning control of the own vehicle for collision avoidance is possible without complicated processing. It becomes possible to provide.

In order to do so, the avoidance target trajectory that the host vehicle 20 can take is acquired.
- the avoidance target trajectory is a trajectory acquired based on the traveling state of the host vehicle 20 such as the vehicle speed and lateral acceleration of the host vehicle 20, for example. Specifically, as shown in FIG. 2, the avoidance target trajectory acquisition unit 101 acquires the current lateral acceleration Gy0 of the host vehicle 20 from the output signal of the acceleration sensor 5, and the host vehicle 20 acquires the current lateral acceleration Gy0.
- the avoidance target trajectory acquisition unit 101 adds, to the current lateral acceleration Gy0 of the host vehicle 20, the maximum lateral force change ⁇ Gy for the host vehicle 20 to turn safely at the current speed of the host vehicle 20.
- the route b1 that the vehicle 20 is predicted to pass is specified, and conversely the route b2 that the vehicle 20 is predicted to pass when the maximum change ⁇ Gy is subtracted from the current lateral acceleration Gy0 of the vehicle 20.

- the method of changing the yaw rate of the vehicle is not limited to the method of changing the rudder angle by the EPS 10, and a method of applying different brake hydraulic pressures to the left and right wheels of the host vehicle 20 may be used.
- the process shown in FIG. 3 is a process routine that is repeatedly executed by the ECU 1, and is stored in advance in the ROM of the ECU 1 as a control program.
- S101 based on the output signal of the external environment recognition device 2, information about the road on which the host vehicle 20 will travel in the future is generated. That is, in the coordinate system with the host vehicle 20 as the origin, the ECU 1 is the position coordinates of the three-dimensional object 30 that can be an obstacle of the host vehicle 20 and an indicator that indicates the lane boundary, and Generate information about posture.
- the process of S101 ends, the process proceeds to S102.
- the ECU 1 determines whether there is a three-dimensional object 30 that becomes an obstacle in the course direction of the host vehicle 20 based on the information generated in S101.
- the “track” here is a route (for example, route a shown in FIG. 2) predicted to pass when the host vehicle 20 travels while maintaining the current lateral acceleration Gy0.
- route a shown in FIG. 2 predicted to pass when the host vehicle 20 travels while maintaining the current lateral acceleration Gy0.
- the process proceeds to S103, and if a negative determination is made, the ECU 1 once ends the execution of this routine.
- the processing according to S101 and S102 corresponds to the processing by the travel path recognition unit 100 described above.
- the avoidance target trajectory acquisition unit 101 reads the current lateral acceleration Gy0 of the host vehicle 20 via the acceleration sensor 5, and the maximum change ⁇ Gy of the lateral acceleration based on the read lateral acceleration Gy0. Is added or subtracted, the travel range in which the host vehicle 20 can travel is calculated, and the travel track in which the interference between the travel range and the three-dimensional object 30 can be avoided is calculated as the avoidance line.
- the avoidance line corresponds to the avoidance target trajectory in the present invention.
- S ⁇ b> 104 there are avoidance lines to be taken in order to prevent the host vehicle 20 from colliding with the three-dimensional object 30 recognized by the support control unit 103 in both the left and right directions of the host vehicle 20 across the three-dimensional object 30. It is determined whether or not there is. This determination is to determine whether or not there are at least one avoidance line in each of the left and right directions (width direction) of the host vehicle 20 with the three-dimensional object 30 as a reference. However, if it exists only in one of the left and right sides of the host vehicle 20 with the three-dimensional object 30 as a reference, a negative determination is made in S104. For example, as shown in FIG.
- the maximum change in lateral acceleration + ⁇ Gy0 is used as an avoidance line.
- the path b11 exists on the corresponding path b1 side
- the path b21 exists on the path b2 side corresponding to the maximum change in lateral acceleration ⁇ Gy in addition to the path b2.
- the routes b1 and b11 as the avoidance lines exist on the right side of the host vehicle 20, and the routes b2 and b21 as the avoidance lines exist on the left side of the host vehicle 20. Therefore, in such a state, an avoidance line exists in both the left and right directions of the host vehicle 20, and therefore an affirmative determination is made in S104.
- the avoidance line In addition to the path b1, the path b11 exists on the path b1 side corresponding to the maximum change in lateral acceleration + ⁇ Gy0, but there is no avoidance line on the path b2 side corresponding to the maximum change in lateral acceleration ⁇ Gy.
- the host vehicle 20 can avoid a collision with the three-dimensional object 30 by turning to the right side, and can also avoid a collision with the three-dimensional object 30 by turning to the left side. .
- the support control unit 103 acts on the EPS 10 and tries to turn in either the left or right direction, the driver of the host vehicle 20 may turn in the opposite direction. Then, as the driver, the driving support processing of the support control unit 103 interferes with the steering of the driver, and thus the processing not conforming to his / her sense is performed.
- the support control unit 103 does not turn the host vehicle 20 by changing the steering angle by the EPS 10 or applying different brake hydraulic pressures to the left and right wheels of the host vehicle 20, and the ECB 11 Decelerate at maximum braking force.
- the support control unit 103 does not control the turning of the host vehicle 20, but the driver is guaranteed to perform steering based on his / her own judgment.
- the driving support processing is performed only for deceleration by the braking force, and turning of the host vehicle 20 by steering is left to the driver's judgment, so that processing that does not follow the driver's sense can be avoided. it can.
- the maximum braking force In order to enable turning by the driver's steering, it is preferable to generate the maximum braking force within a range in which the lateral force necessary for the turning can be generated. If the host vehicle 20 can be sufficiently decelerated before the collision, the braking force for decelerating the host vehicle 20 may be secured in preference to the lateral force for turning by the driver's steering. When the process of S105 ends, this routine is repeated again from the beginning.
- S106 it is determined whether or not the turning control of the host vehicle 20 may be executed in order to avoid a collision with the three-dimensional object 30.
- the determination process is performed by the turning permission unit 102. The details of the determination process by the turning permission unit 102 will be described later. If an affirmative determination is made in S106, the process proceeds to S107, and if a negative determination is made, the process proceeds to S105. In S107 after the affirmative determination is made, driving support processing for avoiding a collision between the three-dimensional object 30 and the host vehicle 20 by the support control unit 103 on the assumption that the turning control of the host vehicle 20 is permitted. That is, driving support processing including control for turning the host vehicle 20 is performed.
- the process according to S107 will be specifically described with reference to FIG. 4B.
- the avoidance line to be taken by the host vehicle 20 exists only in the right direction of the host vehicle 20 with respect to the three-dimensional object 30.
- the host vehicle 20 can avoid a collision with the three-dimensional object 30 only by turning rightward.
- the support control unit 103 changes the rudder angle by the EPS 10 or turns the host vehicle 20 by applying different brake hydraulic pressures to the left and right wheels of the host vehicle 20.
- the driving support process is performed so that the host vehicle 20 travels on one of the routes b1 and b11 illustrated in FIG. 4B.
- deceleration with the braking force by the ECB 11 is also performed, so that the collision with the three-dimensional object 30 can be avoided more safely.
- this routine is repeated again from the beginning.
- an avoidable yaw rate ⁇ which is a yaw rate necessary for the host vehicle 20 to travel on the avoidance line, is calculated for the avoidance line calculated in S103.
- the yaw rate ⁇ is used to calculate the avoidance line as described above, the yaw rate is set as the avoidable yaw rate ⁇ for the avoidance line that does not interfere with the three-dimensional object 30. For example, in the state shown in FIG.
- avoidance line exists only on the right side of the host vehicle 20 with respect to the three-dimensional object 30
- avoidable yaw rates ⁇ 1 and ⁇ 11 are set for the avoidance lines b1 and b11, respectively.
- the two have a correlation of ⁇ 1> ⁇ 11 as can be seen from the difference in turning radius of the host vehicle 20.
- the threshold value ⁇ 0 is a lateral acceleration generated while the host vehicle 20 is turning to allow the driver to override the control while the assist control unit 103 is performing the steering angle control on the EPS 10. It is for setting the upper limit in the absolute value of. For example, 0.2 G to 0.3 G can be adopted as the threshold value ⁇ 0.
- the determination in S202 is that the host vehicle 20 can avoid a collision with the three-dimensional object 30 regardless of which of the avoidance lines calculated in S103 is selected, but the lateral acceleration that occurs at that time.
- This is a process for selecting a part of the avoidance lines from the calculated avoidance lines so that the room for steering by the driver is not narrowed due to an excessively large value.
- a negative determination is made in S202 because the avoidable yaw rate ⁇ cannot be calculated.
- the process proceeds to S203, and if a negative determination is made, the process proceeds to S206.
- the start point Ps of the turn control of the host vehicle 20 is calculated in the avoidance line (only the avoidance line b11 in this embodiment) where the absolute value of the avoidable yaw rate ⁇ is equal to or less than the threshold value ⁇ 0 in S202. Is done.
- the calculation process will be described with reference to FIG.
- the avoidance line b11 shown in FIG. 6 is the same as the avoidance line b11 shown in FIG. 4B.
- the reason why the avoidance line b1 is not selected as the processing target after S203 is that the avoidable yaw rate ⁇ that occurs when the vehicle 20 travels on the avoidance line b1 is larger than the threshold value ⁇ 0.
- the turning control start point Ps is specified as the traveling position of the host vehicle 20 at the time when the ECU 1 issues a command to the EPS 10 or the like to turn the host vehicle. Specifically, when calculating the avoidance line in the processing of S103 described above, the avoidance line is calculated after specifying the point at which the turn control of the host vehicle 20 is started.
- the turning control start point may be set as the turning control start point Ps shown in FIG. In calculating the turning control start point Ps, after the execution of turning control is permitted and a command for starting turning is issued from the ECU 1 to the EPS 10 or the like, the traveling direction of the vehicle 20 is actually driven by driving the EPS 10 or the like.
- the delay time required to change i.e., until the turning motion is started.
- the delay time varies depending on the system, the configuration of the host vehicle 20, and the like, but for example, a time of about 0.3 seconds can be expected. By doing in this way, turning control start point Ps can be specified more correctly.
- a turning control end point Pf at which turning control for avoiding a collision with the three-dimensional object 30 is completed is calculated.
- the turning control end point Pf is defined as follows according to the content of the driving support processing for collision avoidance, but the definition shown below is merely an example, and other definitions may be adopted as appropriate. ⁇ When only turning control is performed as driving support processing>
- the turning control end point Pf may be defined as a point where the traveling direction of the host vehicle 20 starts to be parallel to the direction L1 in which the three-dimensional objects 30 are arranged as a result of turning control.
- the line L1 indicating the direction in which the three-dimensional object 30 is arranged is, for example, a line or outline that passes through the center of gravity of the three-dimensional object 30 based on the shape of the existence area of the three-dimensional object 30 recognized by the traveling path recognition unit 100. It may be specified based on the line along.
- the turn control end point Pf may be defined as a point where the host vehicle 20 starts to move away from the three-dimensional object 30 as a result of the turn control. That is, the turning control end point Pf is specified when it can be determined that the possibility of a collision is reduced by increasing the distance between the host vehicle 20 and the three-dimensional object 30.
- the predetermined avoidance distance L0 is a threshold value for reasonably reasoning that the distance between the host vehicle 20 and the three-dimensional object 30 is close enough to avoid a collision.
- the predetermined avoidance distance L0 is set based on the avoidance distance necessary for realizing the collision avoidance with the three-dimensional object 30 while the host vehicle 20 is traveling at the legal speed of the traveling road surface.
- the distance between the host vehicle 20 and the three-dimensional object 30 is a direction perpendicular to the traveling direction of the host vehicle 20 (in other words, the tangential direction of the avoidance line) and the three-dimensional object 30. The distance between can be adopted. If a positive determination is made in S205, the process proceeds to S206, and if a negative determination is made, the process proceeds to S207.
- the process is performed when a negative determination is made in S202 and a positive determination is made in S205.
- the former case substantially corresponds to the case where the collision with the three-dimensional object 30 cannot be avoided by the turning control of the host vehicle 20, but the turning control is performed even in such a case and the braking control is performed during the turning.
- the three-dimensional object 30 exists in the traveling direction of the host vehicle 20, so that the vehicles around the host vehicle 20 are Therefore, it can be said that there is a reasonable reason why the turning control of the host vehicle 20 can be permitted.
- the latter case corresponds to the case where the collision with the three-dimensional object 30 can be avoided by the turning control of the host vehicle 20, but even in such a case, in the entire range of the turning control section in which the turning control is continuously performed. Since the distance between the host vehicle 20 and the three-dimensional object 30 is equal to or less than the threshold value L0, the host vehicle 20 needs to avoid a collision with the three-dimensional object 30, and The possibility that the vehicle approaches the host vehicle 20 is considered to be extremely low. Therefore, even in such a case, it can be said that there is a reasonable reason why the turning control of the host vehicle 20 can be permitted.
- FIGS. 7A and 7B an example in which the process of S207 is performed is illustrated in FIGS. 7A and 7B.
- the distance L between the host vehicle 20 and the three-dimensional object 30 is not more than the threshold value L0 within a certain range from the turning control start point Ps in the turning control section, but the turning control end point Pf.
- the distance L is substantially infinite.
- FIG. 7B shows a state where the turn control of the host vehicle 20 is to be performed even though there is still a sufficient distance from the three-dimensional object 30. If the own vehicle 20 performs the turn control in such a state, it also results in blocking the traveling direction of the vehicle 40 existing in the vicinity thereof, and thus the turn control is permitted for the own vehicle 20. It is preferable to judge that there is no reasonable existence. In the state shown in FIG. 7B, if the host vehicle 20 approaches the three-dimensional object 30 when the process shown in FIG. 3 is repeated again, and the state shown in FIG. Will be allowed.
- the avoidance line to be taken by the host vehicle 20 when the three-dimensional object 30 is recognized is The content of processing executed by the support control unit 103 is adjusted depending on whether it exists in both the left and right directions. As a result, it is possible to avoid a collision between the host vehicle 20 and the three-dimensional object 30 while providing a driving support process in accordance with the sense of the driver of the host vehicle 20.
- the turning control of the host vehicle 20 is executed based on the judgment of the turning permission unit 102, there is no reason to provide an additional sensor for detecting the presence of a vehicle around the host vehicle. The turn control of the host vehicle 20 can be realized below.
- the turning control of the own vehicle 20 is not performed. Even in such a case, instead of this configuration, it is possible to adopt a configuration in which either one of the left and right avoidance lines is selected and the turning control is performed according to the selection avoidance line. Good. Even in that case, as described above, the turning control of the host vehicle 20 is executed only when the turning permission unit 102 permits the turning control.

Abstract
Description
<運転支援処理として旋回制御のみを行う場合>
旋回制御終了点Pfは、旋回制御の結果、自車両20の進行方向が立体物30の並んでいる方向L1に平行となり始める地点として、定義されてもよい。すなわち、立体物30の並んでいる方向に自車両20の進行方向が平行となることで、自車両20の進行方向がそのまま維持されれば立体物30との衝突を回避することが可能となることをもって、旋回制御の終了点Pfが特定される。なお、立体物30の並んでいる方向を示す線L1は、走路認識部100によって認識された立体物30の存在領域の形状等に基づいて、例えば立体物30の重心を通過する線や輪郭に沿った線に基づいて特定されてもよい。
また、上記の例に代えて、旋回制御終了点Pfは、旋回制御の結果、自車両20が立体物30から離間するように進行し始める地点として、定義されてもよい。すなわち、自車両20と立体物30との間の距離が延びることで衝突の可能性が低下していると判断できることをもって、旋回制御の終了点Pfが特定される。
次に、運転支援処理として旋回制御および制動制御を行う場合には、上述した旋回制御のみを行う場合の、旋回制御終了点Pfの定義例に加えて、旋回制御および制動制御の結果、自車両20が停止する地点を旋回制御終了点Pfとして定義してもよい。すなわち、仮に、自車両20の進行方向が立体物30の並んでいる方向L1に平行な状態に至っていなくても、自車両20が停止することで立体物30との衝突は回避できることをもって、旋回制御の終了点Pfが特定される。
