Description

Vehicle travel control apparatus and method

The present invention relates to a travel control apparatus and method for controlling travel of a vehicle.

With regard to this type of device, a first control threshold based on the first risk on the left side of the vehicle and a second control threshold based on the second risk on the right side of the vehicle are obtained. The first control threshold, which is the distance from the edge, is changed toward the first object on the left side of the vehicle, and the second control threshold, which is the distance from the road edge, increases as the first risk increases. There is known a technique for changing to an object (Patent Document 1).

Japanese Patent No. 5070171

However, in the conventional technology, the travel position of the host vehicle is controlled without considering the relative speed of the vehicle width direction component of the host vehicle with respect to the avoidance target. Therefore, depending on the actual speed, the travel control that avoids the avoidance target is performed. There is a problem that the traveling position of the own vehicle is changed.

The problem to be solved by the present invention is to prevent the travel position of the host vehicle from being changed when the travel control that avoids the avoidance target is being performed.

The present invention obtains the position of the target area along the vehicle width direction in consideration of the relative speed of the vehicle width direction component of the host vehicle with respect to the avoidance target when setting the target area based on the position of the avoidance target. Solve the above problems.

According to the present invention, the higher the relative speed of the vehicle width direction component of the host vehicle with respect to the avoidance target, the longer the distance between the lateral end of the target region and the avoidance target is set. Thus, it is possible to suppress the position of the target route that is set during the travel control from being changed.

Hereinafter, the traveling control apparatus 100 of this embodiment will be described.

As shown in FIG. 1, the travel control device 100 of this embodiment includes a control device 10, a communication device 20, and an output device 30. The communication device 20 exchanges information with the in-vehicle device 200. The output device 30 has the same function as the output device 110 of the in-vehicle device 200 described above. As the output device 30, the output device 110 of the in-vehicle device 110 may be used. When the travel control device 100 is a computer that can be carried by an occupant, the travel control device 100 outputs control information for controlling blinking of the vehicle interior lamp 113 and the vehicle interior lamp 114 of the in-vehicle device 200 to each device. May be.

The control device 10 of the travel control device 100 is configured as a travel control device 100 by executing a ROM (Read Only Memory) 12 in which a program for executing the travel control of the host vehicle is stored and a program stored in the ROM 12. A computer including a CPU (Central Processing Unit) 11 as a functioning operation circuit and a RAM (Random Access Memory) 13 functioning as an accessible storage device.

The control device 10 of the travel control device 100 according to the present embodiment has a target information acquisition function, a vehicle information acquisition function, a region setting function, a route setting function, and a control function. The control apparatus 10 of this embodiment performs each function by cooperation of the software for implement | achieving the said function, and the hardware mentioned above.

Hereinafter, each function of the traveling control apparatus 100 according to the present embodiment will be described.
First, the target information acquisition function of the control device 10 will be described. The control apparatus 10 acquires target information including the position of the avoidance target that the host vehicle should avoid. The avoidance target has a predetermined positional relationship with the host vehicle. The control device 10 acquires target information including the position of the avoidance target detected by the detection device 50. The target information includes a relative position, a relative speed, and a relative acceleration of the avoidance target.

If the avoidance target is another vehicle, and the other vehicle and the host vehicle are capable of inter-vehicle communication, the control device 10 of the host vehicle detects the vehicle speed and acceleration of the other vehicle detected by the vehicle speed sensor of the other vehicle as target information. You may get as Of course, the control device 10 can also acquire target information including the position, speed, and acceleration of other vehicles from an external device of the intelligent transportation system.

The vehicle information acquisition function of the control device 10 will be described. The control device 10 acquires host vehicle information including the position of the host vehicle. The position of the host vehicle can be acquired by the position detection device 121 of the navigation device 120. The own vehicle information includes the vehicle speed and acceleration of the own vehicle. The control device 10 acquires the speed of the host vehicle from the vehicle speed sensor 62. The speed of the host vehicle can also be acquired based on the change over time of the position of the host vehicle. The acceleration of the host vehicle can be obtained from the speed of the host vehicle. The host vehicle information includes the position of the host vehicle at a future time determined from the current position of the host vehicle and the vehicle speed. Based on the position of the host vehicle at the future time, the positional relationship between the host vehicle and the avoidance target at the future time can be obtained.

The area setting function of the control device 10 will be described. The control device 10 sets the target area based on the position of the avoidance target included in the acquired target information. The avoidance target is a three-dimensional object that exists around the host vehicle and should be avoided.

2A to 2C are diagrams illustrating an example of a method for setting the target region R. FIG. In the example shown in FIGS. 2A to 2C, the traveling direction Vd1 of the host vehicle is the + y direction in the figure. In the figure, the extending direction of the traveling lane Ln1 on which the host vehicle travels is also the + y direction in the figure.

FIG. 2A is a view of the state where the other vehicle V2 parked on the left shoulder side of the travel lane Ln1 of the host vehicle V1 is detected as viewed from above. FIG. 2A shows a scene in which the host vehicle V1 approaches the other vehicle V2 from behind, passes through the side of the other vehicle V2 (avoidance target), and travels in the lane Ln1 in the traveling direction Vd1. The other vehicle V2 to be avoided exists in front of the host vehicle V1. The detected other vehicle V2 exists in the travel lane Ln1 on which the host vehicle V1 travels, and prevents the host vehicle V1 from going straight, and is therefore an avoidance target that the host vehicle V1 should avoid.

In this example, when the own vehicle V1 approaches the avoidance target V2 along the traveling direction Vd1, the control device 10 sets the target region R0 based on the relationship between the position of the own vehicle and the avoidance target position ( Hereinafter, R including R1 and R2 may be collectively referred to as R). The target region R may be set from the viewpoint of avoiding an approaching state or a contact state in which the distance between the host vehicle V1 and the avoidance target V1 is less than the predetermined value X1, or between the host vehicle V1 and the avoidance target V1. It may be set from the viewpoint of keeping the distance at or above the predetermined value X2.

The control device 10 sets the target region R in a predetermined range including the other vehicle V2. The control device 10 sets the target region R based on the position of the avoidance target such as the other vehicle V2. The “position to avoid” used in setting the target area R can be defined in advance. When the avoidance target is the other vehicle V2, the position of the center of gravity of the other vehicle V2, the center position, any position of the front portion of the other vehicle V2, any position of the rear portion of the other vehicle V2, Any position of the left and right door portions can be defined as “the position of the other vehicle V <b> 2”. The control device 10 sets the target region R with reference to the “position to be avoided”. In the drawing, the target region R0 is described as an example, but the same applies to target regions R1 and R2 described later.

In the present embodiment, the target region R0 may have a shape that follows the outer shape of the other vehicle V2, or may have a shape that includes the other vehicle V2. Further, the control device 10 may set the boundary of the target region R0 to a shape along the outer shape of the other vehicle V2, or may be a circle, an ellipse, a rectangle, or a polygon that includes the other vehicle V2. Further, the target area R0 may be set so that the boundary of the target area R0 is less than a predetermined distance (A) from the surface (outer edge) of the other vehicle V2, and the area of the target area R0 may be set small. The area of the target region R0 may be set to be larger than the predetermined distance B (B> A) separated from the other vehicle V2.

The target area R0 shown in FIG. 2A is defined by a rectangular shape that encompasses the other vehicle V2. As shown in FIG. 2A, in the case where the traveling direction Vd1 of the host vehicle is defined as the front and the opposite direction is defined as the rear, the target region R0 has front and rear end portions RL1, RL2. The front and rear end portions RL1 and RL2 are end lines that define the length of the target region R0 along the extending direction (+ y) of the traveling lane Ln1 of the host vehicle. The length along the extending direction (+ y) of the travel lane Ln1 of the target region R0 illustrated in FIG. 2A is L0 which is the distance between (y1) and RL2 (y2) of the front and rear end portions RL1. Of the front and rear end portions RL1 and RL2, a front and rear end portion located on the near side (upstream side) when viewed from the host vehicle V1 approaching the target region R0 is defined as a first end portion RL1. On the other hand, out of the front and rear end portions RL1 and RL2, a front and rear end portion located on the back side (downstream side) when viewed from the own vehicle V1 approaching or passing through the side to be avoided is referred to as a second end portion RL2. The first end RL1 and the second end RL2 are set according to the distance from the position (reference position) V20 of the other vehicle V2. The first end RL1 and the second end RL2 are located on the boundary of the target region R0.

As shown in FIG. 2A, when the vehicle width direction of the host vehicle is defined as Vw1 (X direction in the figure), the target region R0 has left and right end portions RW1 and RW2 on the left and right sides thereof. The left and right end portions RW1 and RW2 are end lines (end portions) that define a distance along the vehicle width direction from the host vehicle V1. The left and right end portions RW1 and RW2 are end lines that define the length (width) of the target region along the road width direction (X) of the travel lane Ln1 of the host vehicle. The length along (X) in the road width direction of the target region R0 shown in FIG. 2A is a distance W0 between the left end RW1 (end on the lane marker x1 side) and the right end RW2 (end on the lane marker x2 side). is there. When the host vehicle approaches the avoidance target V2 along the vehicle width direction, left and right end portions of the left and right end portions RW1 and RW2 of the target region R0 that are located to the side of the host vehicle V1 when viewed from the host vehicle V1 Is the first lateral end RW1. On the other hand, of the left and right end portions RW1 and RW2, the left and right end portions located on the side (road shoulder side) opposite to the side of the own vehicle V1 when viewed from the own vehicle V1 are defined as the second lateral end portion RW2. The first lateral end RW1 and the second lateral end RW2 can be set according to the distance from the position (reference position) V20 of the other vehicle V2. The first horizontal end RW1 and the second horizontal end RW2 are located on the boundary of the target region R0.

As shown in FIG. 2A, when there is an oncoming vehicle V3 that faces the opposite lane Ln2 of the traveling lane Ln1 of the host vehicle V1, the control device 10 detects the oncoming vehicle V3 as an avoidance target. Although not shown in the figure, the control device 10 sets a target region in a range including the oncoming vehicle V3 by the same method.

From the viewpoint that the appropriate length of the target region R0 set to avoid the other vehicle V2 is different when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is different. The length L0 of the target region R0 along the extending direction (+ y) of the lane in which the host vehicle V1 travels is set according to the relative speed of the host vehicle V1 with respect to the other vehicle V2 to be avoided. The control device 10 may define the distance dRL as an interval to be secured from the position y0 of the host vehicle V1 to the first end RL1.

Incidentally, the target region R0 is set at the timing when the avoidance target is detected, that is, at the timing before the operation for turning for avoidance (steering operation or the like) is performed. If the target area R0 is set by a uniform method without considering the relative speed of the host vehicle V1 with respect to the avoidance target, the target route RT1 calculated based on the boundary of the target area R0 may be obtained depending on the actual relative speed. You may have to change it. When the target route RT1 is changed, the turning amount, turning angle, vehicle speed, acceleration, and the like are changed, so that the continuity of the behavior of the vehicle cannot be maintained. An occupant may feel uncomfortable with such vehicle behavior.

On the other hand, in the present embodiment, the length of the target region R1 along the extending direction (+ y) of the lane on which the host vehicle V1 travels depends on the actual relative speed of the host vehicle V1 with respect to the other vehicle V2 to be avoided. Since the length L1 is set, an appropriate target region R1 can be set. According to the target route RT1 that is set according to the relative speed and is set based on the position of the boundary of the target region R1, the target route RT1 is suppressed from being changed during the execution of the travel control. . For this reason, the turning amount, turning angle, vehicle speed, acceleration, and the like of the host vehicle are not suddenly changed. As a result, the continuity of the behavior of the vehicle is maintained, so that the occupant does not feel discomfort.

Based on FIG. 2B, a process of setting the target region R1 having the length L10 according to the relative speed of the host vehicle V1 with respect to the other vehicle V2 as an avoidance target will be described. The target area R1 shown in FIG. 2B is an area set on the assumption that the relative speed of the host vehicle V1 with respect to the other vehicle V2 is higher than the relative speed of the host vehicle V1 described in FIG. 2A. In FIG. 2B, for convenience of explanation, the target region R0 set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is low is set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is high. This is shown superimposed on the target region R1.

The control device 10 of the present embodiment sets the length L10 of the target region R1 along the extending direction of the lane in which the host vehicle V1 travels as the relative speed of the host vehicle V1 with respect to the other vehicle V2 increases. The relative speed of the host vehicle V1 relative to the other vehicle V2 referred to when adjusting the length L10 of the target region R1 may be a relative speed of the vehicle length direction component of the host vehicle V1, or the vehicle width direction component and the vehicle length. It may be a relative speed obtained by synthesizing the direction components. In the host vehicle V1 approaching the avoidance target (straightly traveling), the relative speed of the vehicle length direction component is larger than the relative speed component of the vehicle width direction, so the degree of approach to the avoidance target is also determined by the combined relative speed. I can judge.
The length L10 of the target area R1 set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is high is the length L0 of the target area R0 set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is low. Longer (L10> L0). In the present embodiment, when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is high, the length L0 of the target region R0 is increased. Therefore, the length of the target route RT when passing the side of the avoidance target V2 is increased. it can. That is, since the distance between the points where the turning operation for passing the side of the other vehicle V2 is performed can be increased, the turning amount and the turning speed of the host vehicle V1 during the turning operation can be controlled to be low. If the turning amount and the turning speed can be suppressed low, it is possible to suppress the speed and acceleration of the host vehicle V1 from being changed. As a result, traveling control can be executed so that the passenger does not feel uncomfortable.

In the present embodiment, as a method of extending the length of the target region R1, the first end portion RL1a positioned on the near side when viewed from the host vehicle V1 is set on the host vehicle V1 side, and the method of viewing from the host vehicle V1. There is a method in which the second end portion RL2a located on the far side is set on the far side in the traveling direction of the host vehicle V1.

As the relative speed of the host vehicle V1 with respect to the other vehicle V2 is higher, the control device 10 is closer to the front side of the front and rear end portions RL1a, RL2a of the target region R1 as viewed from the host vehicle V1 (opposite direction of travel: -y direction in the figure) The target region R1 is set so that the distance between the first end RL1a located at the same position and the other vehicle V2 becomes longer. That is, as the relative speed of the host vehicle V1 with respect to the other vehicle V2 is higher, the first end RL1a is set to a position on the host vehicle V1 side. In the example shown in FIG. 2B, the position of the first end RL1a of the target region R1 when the relative speed is VR2 is the first end RL1a of the target region R0 when the relative speed is VR0 (VR1> VR0). It shifts to the own vehicle V1 side by the distance L1 from the position of. Since the curved point (turning start point) of the target route RT1a set so that the own vehicle V1 passes the side to be avoided can be shifted to the own vehicle V1 side, the turning amount (steering amount of the turning amount at the turning start point) can be changed. Including, the same shall apply hereinafter), and the turning speed (including the steering speed, the same shall apply hereinafter) can be controlled low.

As the relative speed of the host vehicle V1 with respect to the other vehicle V2 is higher, the control device 10 has a rear side (traveling direction side: + y direction in the figure, below) of the front and rear end portions RL1a and RL2a of the target region R1 as viewed from the host vehicle V1. The target region R1 is set so that the distance between the second end portion RL2a located at the same position and the other vehicle V2 becomes longer. That is, as the relative speed of the host vehicle V1 with respect to the other vehicle V2 is higher, the second end RL2a is set to a position on the back side of the host vehicle V1. In the example shown in FIG. 2B, the position of the second end RL2a of the target region R1 when the relative speed is VR2 is the second end RL2a of the target region R0 when the relative speed is VR0 (VR1> VR0). The vehicle shifts toward the traveling direction side of the host vehicle V1 by a distance L2 from the position of. The host vehicle V1 passes the side of the avoidance target and the inflection point of the target route RT1a set to return to the center position of the lane Ln1 (turning completion point: return point to the straight traveling state) is on the traveling direction side of the host vehicle V1. Therefore, the turning amount and turning speed at the turning completion point can be controlled to be low.

This makes it possible to avoid the other vehicle V2 and form a target route with a gentle curve when passing the target region R1. That is, since the turning amount and the turning speed of the host vehicle V1 can be controlled to be low, it is possible to execute traveling control that does not give the passenger a sense of incongruity.

From the above-described setting method of the target region R1 in which the first end portion RL1a located on the near side as viewed from the host vehicle V1 among the front and rear end portions RL1a and RL2a of the target region R1 is positioned on the near side, and the own vehicle V1. The method of setting the target region R1 with the second end RL2a positioned on the back side as viewed from the back side as viewed from the back side may be applied independently, or both methods may be applied simultaneously. That is, when extending the length of the target region R1, only the first end portion RL1a may be shifted to the own vehicle V1 side approaching the avoidance target, or only the second end portion RL2a is shifted to the own vehicle V1. You may shift to the advancing direction side. Of course, the second end RL2a may be shifted toward the traveling direction of the host vehicle V1 while extending the first end RL1a toward the host vehicle V1 approaching the avoidance target. When the avoidance target is a stationary object or a moving object that moves at a low speed, the shift amount of the first end RL1a and the second end RL2a may be controlled based on the speed of the host vehicle V1.

Subsequently, based on FIG. 2C, the distance along the vehicle width direction between the host vehicle V1 and the target region R2 is controlled according to the relative speed of the vehicle width direction component of the host vehicle V1 with respect to the other vehicle V2 to be avoided. Processing will be described. The target region R2 shown in FIG. 2C is set under the condition that the relative speed of the vehicle width direction component of the host vehicle V1 with respect to the other vehicle V2 is higher than the relative speed of the vehicle width direction component of the host vehicle V1 described in FIG. 2A. This is the area that has been In FIG. 2C, for convenience of explanation, the target region R0 set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is low is set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is high. This is shown superimposed on the target region R2.

The control apparatus 10 of this embodiment passes the side of the other vehicle V2 among the left and right end portions RW1, RW2 of the target region R as the relative speed of the vehicle width direction component of the host vehicle V1 with respect to the other vehicle V2 is higher. The target region R2 is set so that the distance between the lateral end RW1 (closest to the host vehicle V1) located on the host vehicle V1 side when viewed from the host vehicle V1 and the other vehicle V2 to be avoided is increased. To do. That is, as the relative speed of the vehicle width direction component of the host vehicle V1 with respect to the other vehicle V2 is higher, the first lateral end RW1 is set at a position further away from the other vehicle V2. In the example shown in FIG. 2C, the position of the first lateral end RW1a of the target area R1 when the relative speed in the vehicle width direction is VR4 is the position of the target area R0 when the relative speed is VR3 (VR4> VR3). The distance from the other vehicle V2 is shifted by a distance W1 from the position of the first lateral end RW1a. The position of the first lateral end RW1a is shifted to the target route RT side of the host vehicle V1 provided on the side of the other vehicle V2. In the present embodiment, when the relative speed of the vehicle width direction component of the host vehicle V1 with respect to the other vehicle V2 is high, the position of the first lateral end RW1a of the target region R1 is shifted to a position away from the other vehicle V2. The host vehicle V1 moves along the target route RT based on the position of the target region R1 set in this way. That is, it is possible to prevent the host vehicle V1 from being too close to the other vehicle V2 (approaching a predetermined distance or more). As a result, it is possible to execute the traveling control that matches the driving feeling when the occupant avoids the avoidance target and that does not feel uncomfortable.

In FIG. 2C, the position of the host vehicle V1 at one timing among the positions of the host vehicle V1 at a plurality of timings when passing the side of the other vehicle V2 is shown as V1t. The timing or position when passing the side of the other vehicle V2 can be arbitrarily defined by the distance and angle between the other vehicle V2 and the host vehicle V1. The “side of the other vehicle V2” includes a front side (right front, left front) and a rear side (right rear, left rear).

Incidentally, the control device 10 of the present embodiment executes a process of predicting the future position of the host vehicle V1 based on various types of vehicle information in order to calculate an appropriate target route RT. In this embodiment, the lateral position (position along the x direction) of the host vehicle V1 at each timing when passing the side to be avoided can be predicted in the future. Based on the predicted lateral position of the host vehicle V1, the control device 10 can calculate the position of the lateral end RW1 of the target area R to be avoided that is approaching.

Note that, by changing the position of the lateral end RW1 of the target region R, the width W10 of the target region R1 is also changed. The width W10 of the target region R1 of the present embodiment is defined based on the position of the lane marker (for example, x1) on the avoidance target side. The width W10 of the target area R1 set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is higher than the width W0 of the target area R0 set when the relative speed of the host vehicle V1 with respect to the other vehicle V2 is low. Large (W10> W0).

In addition, the control device 10 sets the target region R2 so that the distance between the lateral end RW1b of the target region R2 and the other vehicle V2 increases as the distance along the vehicle width direction of the host vehicle V1 with respect to the other vehicle V2 is shorter. Can be set. In the present embodiment, the closer the host vehicle V1 and the other vehicle V2 are along the vehicle width direction, the more the lateral end RW1b located on the host vehicle V1 side is shifted to a position separated from the other vehicle V2. By separating the lateral end RW1b of the target region R2 from the other vehicle V2, the lateral position (position in the x direction) of the target route RT1b can be separated from the other vehicle V2. As a result, the host vehicle V1 traveling along the target route RT1b does not approach the other vehicle V2 too much.

Next, a specific method for setting the target region R0 will be described with reference to FIGS. 3A and 3B. It is the lateral end RW1 adjacent to the host vehicle V1 among the left and right ends of the target region R0 (including R1 and R2 described above) that affects the target route RT of the host vehicle V1 that travels. The horizontal position of the target region R0 as a target is the position of the horizontal end RW1 located on the host vehicle V1 side.

As shown in FIG. 3A, when the width from the lane marker x1 on the shoulder side of the target region R is W0, the sum (W0 + VW) of the width W0 and the width VW of the host vehicle V1 is greater than the travel lane width LW. When the vehicle is small, the host vehicle V1 can travel to the side of the avoidance target OB1. In the present embodiment, the position of the target region R (distance in the width direction between the lane marker x1 on the road shoulder side and the lateral end RW1 on the own vehicle V1 side: one aspect of the side distance) is calculated so as to satisfy the above condition. The position of the lateral end RW1 of the target region R may be defined by the distance from the lane marker x1 on the road shoulder side, or may be defined by the width W0 of the target region R. Further, the lateral end RW1 of the target region R may be defined by the distance from the lane marker x2 on the opposite lane side of the lane Ln1.

Furthermore, in the present embodiment, in consideration of the safety allowance d1 that should be secured at least between the host vehicle V1 and the target region R0, and the allowance allowance d2 that allows the passenger to pass the side of the avoidance target OB1 with peace of mind, The horizontal position RW1 of the target region R0 or its width W0 ′ may be set. These d1 and d2 may be set together or may be set separately. In this case, the control device 10 calculates the width W0 of the target region R0 such that W0 + VW + (d1 / or d2) <LW. The travel lane width LW may be calculated based on the road width LW2 and the number of lanes included in the road information 122, or the position of a pair of lanes is detected from the image information of the detection device 50, and the image information is displayed. Based on this, the lane width may be calculated. The width VW of the host vehicle V1 is acquired from the vehicle controller 70.

The width W0 of the target area R0 may be a distance from either one of the pair of lane markers x1 and x2 defining the lane on which the host vehicle V1 travels to the end RW1 on the host vehicle V1 side of the target area R0. The position of the lateral end RW1 on the host vehicle V1 side of the target region R0 may be defined by the distance from the host vehicle V1 when traveling on the side of the avoidance target OB1. Although not particularly limited, the dimension of the width W0 may be a value proportional to the square of the relative speed of the host vehicle V1 with respect to the avoidance target OB1.

Further, as shown in FIG. 3A, in the present embodiment, when there is an oncoming vehicle V3 that runs opposite to the opposite lane that faces the running lane of the host vehicle V1, a target region R3 that includes the oncoming vehicle V3 is set. . The target region R3 is set by the same method as the method for setting the target region R1 described above. The lateral end RW3 on the host vehicle V1 side of the target region R3 is set based on the position of the oncoming vehicle V3.

In this example, the host vehicle V1 cannot travel beyond the lane marker x2. In this case, the control device 10 calculates the width W0 of the target region R0 so that W0 + VW + (d1and / ord2) + dV1 <LW2. That is, when the relationship of VW <LW2− (W0 ′ + dV1) is established, the host vehicle V1 can pass the opposite oncoming vehicle V3 while avoiding the parked other vehicle V2. If the above relationship is not established, the host vehicle V1 stops in front of the other vehicle V2 (−y side) and waits for the timing when the oncoming vehicle V3 passes by the side of the host vehicle V1. In addition, dV1 is a width | variety ensured at least when the own vehicle V1 drive | works, such as the width | variety of an opposing lane.

Furthermore, as shown in FIG. 3B, the same applies to the case where the avoidance target is a road structure such as the median strip OB4. As shown in the figure, the target region R4 is set so as to include the central separation band OB4. In this case, the control device 10 calculates the dimension (distance between the end portions) of the width W0 of the target region R0 so that W0 + VW + (d1 and / or sd2) + d4 + W4 * (1/2) <LW.

Next, based on FIG. 4A to FIG. 4C, a method for setting the target region R applied in a scene where the host vehicle V1 and the other parked vehicle V2 and oncoming vehicle V3 that are to be avoided pass each other will be described. When the avoidance target is detected, the control device 10 detects that the passing of the avoidance target and the own vehicle V1 starts (the position) and the passing completion point (position), and the own vehicle V1 passes the avoidance target. The starting point (position) and the point (position) where overtaking is completed are calculated.

As shown in FIG. 4A, the control device 10 detects an overtaking start position PS2 where the distance between the front end of the host vehicle V1 and the target region R2 is less than a predetermined value based on the host vehicle information and the target information. When the position in the Y-axis direction of the front end portion of the host vehicle V1 and the rear end portion of the other vehicle V2 parked in front substantially coincide with each other (when the distance becomes less than a predetermined value), the host vehicle V1 Start overtaking V2. The overtaking start position at which the host vehicle V1 starts to overtake another vehicle V2 that is parked is PS2.

The control device 10 detects a passing start position PS3 where the distance between the front end of the host vehicle V1 and the target region R3 is less than a predetermined value. When the position in the Y-axis direction of the front end portion of the host vehicle V1 substantially coincides with the front end portion of the oncoming vehicle V3 that travels oppositely (when the distance becomes less than a predetermined value), both start to pass each other. The passing start position between the oncoming vehicle V3 and the host vehicle V1 during oncoming travel (moving) is PS3.

The control device 10 acquires the own vehicle information and the target information at the overtaking start position PS2 and the passing start position PS3 based on the current own vehicle information and the target information. The control device 10 sets the target region R based on the own vehicle information and the target information at the overtaking start position PS2 and the passing start position PS3.

In the present embodiment, the control device 10 calculates the overtaking start position PS2 and the passing start position PS3 at a predetermined period. As a result, an accurate overtaking start position PS2 and a passing start position PS3 can be obtained. Then, after the own vehicle V1 starts overtaking the other vehicle V2 that is actually the avoidance target, the calculation of the overtaking start position is finished, and after the passing of the oncoming vehicle V3 is started, the passing start position calculation processing is performed. Exit. Then, traveling control of the host vehicle V1 is executed so as to avoid the target region R set from the target information at the overtaking start position PS2 and the passing start position PS3. The timing of traveling in the vicinity of the overtaking start position PS2 and the passing start position PS3 is a timing at which the host vehicle V1 and the avoidance target are most likely to approach each other. By setting the target region R based on the target information at the overtaking start position PS2 and the passing start position PS3 and avoiding this, it is possible to execute highly safe travel control.

The control device 10 determines the front and rear end portions of the target regions R2 and R3 based on the own vehicle information at the overtaking start position PS2 and the passing start position PS3 and the target information of the other vehicles V2 and V3 (avoidance targets) obtained from the target information. The position RL1 of the first end located on the near side when viewed from the host vehicle V1 is set. The target information includes any information on the position, speed, or acceleration of the avoidance target (other vehicle). The own vehicle information includes information on the position, speed, or acceleration of the own vehicle.
Based on the own vehicle information at the overtaking start position PS2 and the passing start position PS3 and the target information of the other vehicles V2, V3 (avoidance targets), the control device 10 determines the own vehicle V1 among the left and right ends of the target regions R2, R3. The position RW1 of the lateral end located on the side is set. Based on the relative positions of the overtaking start position PS2 and the passing start position PS3 with the other vehicles V2, V3, the first end position RL1, the second end position RL2, and the lateral end position RW1 of the target regions R2, R3. By setting, other vehicles V2, V3 can be avoided. When the avoidance target is a moving body like the oncoming vehicle V3, the positional relationship between the host vehicle V1 and the oncoming vehicle V3 changes every moment. According to the present embodiment, an appropriate target region R3 can be set based on the positional relationship when the host vehicle V1 and the oncoming vehicle V3 actually pass each other.

Further, when the passing start position PS3 with the oncoming vehicle V3 that runs opposite is less than a predetermined distance from the front end RL1 on the host vehicle V1 side of the target region R3 (or the oncoming vehicle V3), The vehicle may decelerate and wait for the oncoming vehicle V3 to pass by the side of the host vehicle V1. After the oncoming vehicle V3 passes, the vehicle may pass through a region including the passing start position PS3.

When a plurality of overtaking start positions and passing start positions are detected within a range where the distance from the host vehicle V1 is within a predetermined value, that is, when the host vehicle V1 is passing within a predetermined distance, the control device 10 may simultaneously pass. When passing by a plurality of avoidance targets, a weighting coefficient corresponding to the relative position between the host vehicle V1 and each avoidance target is obtained. This weighting coefficient is a coefficient corresponding to the degree of caution with respect to a plurality of avoidance targets that the host vehicle V1 passes or passes. The control device 10 calculates, for each avoidance target, a weighting factor corresponding to the relative position between the own vehicle and the avoidance target from the own vehicle information and the target information.

For an avoidance target that approaches the host vehicle V1 like the oncoming vehicle V3 and passes by the own vehicle V1, the weighting coefficient is higher than that of the avoidance target that is stationary like the other vehicle V2 that is parked and overtaken by the host vehicle V1. Is set. For an avoidance target having a high relative speed with the host vehicle V1 such as the oncoming vehicle V3 that the host vehicle V1 passes by, the relative speed with the host vehicle V1 like the other vehicle V2 that is parked in front of the host vehicle V1 is overtaking. A higher weighting factor than the avoidance target with a low is set. For an avoidance target that is close to the host vehicle V1, a higher weight coefficient is set than an avoidance target that is far from the host vehicle V1. For an avoidance target having a large relative distance to the host vehicle V1, a higher weighting coefficient is set than an avoidance target having a small relative distance to the host vehicle V1.

Then, in accordance with the calculated weighting factor, the control device 10 sets the position of the lateral end RW1 located on the side of the host vehicle V1 when viewed from the host vehicle V1 among the left and right ends of the target region R2 to be avoided. . In the present embodiment, the position of the lateral end RW1 is shifted to a position separated from the avoidance target (to the own vehicle V1 side) as the weighting factor is higher. In the example shown in FIG. 4A, the distance d13 along the vehicle width direction between the target region R3 to be avoided approaching the host vehicle V1 and the host vehicle V1 is the distance between the target region R2 to be avoided at rest and the host vehicle V1. It is longer than the distance d1 (or d1 + d2) along the vehicle width direction (d13> d1 (d1 + d2)). The distance d13 along the vehicle width direction between the target area R3 to be avoided whose relative speed with the lane marker own vehicle V1 is high and the own vehicle V1 is in the vehicle width direction between the target area R2 with the low relative speed and the own vehicle V1. It is longer than the distance d1 (or d1 + d2) along (d13> d1 (d1 + d2)). The distance d13 between the avoidance target area R3 and the own vehicle V1 that is short in the vehicle width direction and the own vehicle V1 is the avoidance target area R2 and the own vehicle V1 that are long in the vehicle width direction and the own vehicle V1. Is longer than the distance d1 (or d1 + d2) (d13> d1 (d1 + d2)).

Although it is an example, the state of FIG. 4A will be described as an example. As shown in FIG. 4A, the host vehicle V1 travels between the other vehicle V2 that is parked on the left hand and the oncoming vehicle V3 that travels in the adjacent facing lane. At this time, a traveling space having a width of VW10 (or VW10 ′) is given to the host vehicle V1. The control device 10 assigns weight coefficients to the left and right target areas R2 and R3 of the host vehicle V1, respectively. The control device 10 sets a weighting factor WH1 for the target region R2 of the other vehicle V2 that is parked, and a weighting factor WH2 for the target region R3 of the oncoming vehicle V3 that runs oppositely. The control device 10 sets the distance between the lateral end RW1 on the host vehicle V1 side and the other vehicle V2 among the left and right ends of the target region R2 using each weighting factor WH1. Similarly, for the target region R3, the distance between the lateral end RW1 located on the host vehicle V1 side and the oncoming vehicle V3 is set.

The control device 10 may set the width W0 (or W0 ′) of the lateral end RW1 of the target region R0 from the lane marker x1 on the other vehicle V2 side. The control device 10 may set W3 ′ from the lane marker x3 on the oncoming vehicle V3 side to the lateral end RW1 of the target region R3.
Width W0 '= VW10 · xWH1 / (WH1 + WH2)
Width W3 '= VW10 · xWH2 / (WH1 + WH2)
By relatively increasing WH2 related to the target area R3 of the oncoming vehicle V3 that runs oppositely (WH2> WH1), the distance d13 along the vehicle width direction between the target area R3 of the oncoming vehicle V3 that runs opposite to the host vehicle V1. Can be longer than the prescribed distance applied at normal times. Thereby, it can prevent that the own vehicle V1 approaches too much the oncoming vehicle V3 which opposes.

In this way, by using the weighting factor, the position of the lateral end RW1 of the target region R0 is set for an avoidance target that is close to the host vehicle V1 and / or an avoidance target that has a large relative speed with the host vehicle V1. Further away from other vehicles V2, V3. Thus, the host vehicle V1 traveling on the target route RT based on the target region R0 can be prevented from approaching the other vehicles V2, V3 too much. Thereby, the risk at the time of approaching the avoidance target can be reduced.

Next, based on FIG. 4B and FIG. 4C, a method for setting the target regions R2 and R3 in consideration of the position where the overtaking and passing have been completed will be described. Based on the host vehicle information and the target information, the control device 10 detects positions that increase after the distance between the rear end of the host vehicle V1 and the target region R2 decreases as the overtaking completion position PE2 and the passing completion position PE3. . When the position in the Y-axis direction of the rear end portion of the host vehicle V1 and the front end portion of the parked other vehicle V2 substantially coincide with each other (when the distance becomes less than a predetermined value), the control device 10 It is determined that the overtaking has been completed. The overtaking completion position where the host vehicle V1 has overtaken the other vehicle V2 being parked is PE2. Also, when the position in the Y-axis direction of the rear end of the host vehicle V1 and the rear end of the oncoming vehicle V3 that runs opposite each other substantially coincides (when the distance is less than a predetermined value), Judge that completed. The passing completion position between the oncoming vehicle V3 and the host vehicle V1 during the opposite running (moving) is PE3. The control device 10 acquires the own vehicle information and the target information at the overtaking completion position PE2 and the passing completion position PE3 based on the current own vehicle information and the target information. The control device 10 sets the target region R based on the own vehicle information and the target information at the overtaking completion position PE2 and the passing completion position PE3.

In the present embodiment, the control device 10 calculates the overtaking completion position PE2 and the passing completion position PE3 at a predetermined cycle. Thereby, the overtaking completion position PE2 and the passing completion position PE3 can be obtained. The distance d13 between the target region R3 and the host vehicle V1 at the passing completion position with the oncoming vehicle V3 is maintained for a predetermined time. That is, in the state of FIG. 4B, the distance d13 between the target region R3 and the host vehicle V1 is kept constant for a predetermined time after the host vehicle V1 passes the passing completion position PE3. Further, the marginal distances d1 and d2 between the host vehicle V1 and the target region R1 are also kept constant over a predetermined time. As a result, the distance W0 ′ from the lane marker x1 to the host vehicle V1 is also kept constant over a predetermined time. After the own vehicle V1 actually overtakes the other vehicle V2 that is the avoidance target, the overtaking completion position calculation process is terminated. After the passing of the own vehicle V1 with the oncoming vehicle V3 to be avoided is completed, the calculation process of the passing completion position is terminated.

When setting the target areas R2 and R3, the control device 10 determines the target area R2 based on the own vehicle information at the overtaking completion position PE2 and the passing completion position PE3 and the target information of the other vehicles V2 and V3 (avoidance targets). The position RL2 of the second end portion on the far side as viewed from the host vehicle is set. As shown in FIG. 4B, the control device 10 of the present embodiment aligns the position RL2 of the second end portion of the target region R3 with the passing completion position PE3. Thus, the traveling control is executed based on the target region R3 having the same width W3 until the passing completion timing. It can be prevented from turning until at least the passing is completed. When the passing is completed, the host vehicle V1 returns to an appropriate position (the center of the travel lane).

Further, as shown in FIG. 4C, the passing completion position PE3 may be shifted to the traveling direction side of the host vehicle V1. That is, the position RL2 of the second end portion of the target region R0 is shifted to the back side (traveling direction side) as viewed from the host vehicle V1 with respect to the passing completion position PE3. Thereby, after completion of passing, traveling control is executed in a state where the distance between the host vehicle V1 and the target region R3 along the vehicle width direction is maintained for a predetermined time. Since the same control content is maintained after the passing is completed, it is possible to prevent the turning from being executed immediately after the passing is completed. Then, after the passing is completed and the vehicle travels the shift amount (distance L3), the host vehicle V1 returns to an appropriate position (the center of the travel lane). This process can also be applied at the time of passing the overtaking completion position PE2.

Note that the shift amount L3 of the passing completion position PE3 can be determined according to the vehicle speed of the host vehicle V1. The shift amount L3 of the passing completion position PE3 is preferably reduced as the vehicle speed of the host vehicle V1 increases. By shifting the passing completion position PE3 to the far side in the traveling direction, the distance L3 from the oncoming vehicle V3 of the target region R3 can be relatively increased. This distance L3 corresponds to the shift amount of the passing completion position PE3 described above. The control device 10 decreases the extension amount of the second end portion RL2 of the target region R3 to the far side as the vehicle speed of the host vehicle V1 is higher. This process can also be applied to the overtaking completion position PE2.

Similarly, the control device 10 determines the left and right ends of the target region R3 based on the own vehicle information at the overtaking completion position PE2 and the passing completion position PE3 and the target information of the other vehicles V2 and V3 (avoidance target) obtained from the target information. The position of the lateral end RW1 located on the own vehicle V1 side is set. The first ends of the target areas R0 and R3 based on the relative positions of the own vehicle V1 from the overtaking start position PS2 closest to the other vehicles V2 and V3 to be avoided to the overtaking completion position PE2 with respect to the other vehicles V2 and V3. Position RL1, second end position RL2, and lateral end position RW1 are set. Similarly, the position RL1 of the first end of the target areas R0 and R3, the position RL2 of the second end, the horizontal end of the target areas R0 and R3 based on the relative position with the other vehicles V2 and V3 from the passing start position PS3 to the passing completion position PE3. The position RW1 of the part is set. Thereby, target area | region R2, R3 which the own vehicle V1 can avoid the other vehicles V2, V3 can be set. In particular, when the object to be avoided is a moving body such as the oncoming vehicle V3, the positional relationship between the host vehicle V1 and the oncoming vehicle V3 changes every moment, but according to this embodiment, the closest approach when actually passing each other An appropriate target region R3 can be set according to the positional relationship to be performed.

The control device 10 accelerates when the passing completion position PE3 with the oncoming vehicle V3 that runs opposite is less than a predetermined distance from the rear end RL2 on the host vehicle V1 side of the target region R3 (or oncoming vehicle V3). The oncoming vehicle V3 may pass by the side of the oncoming vehicle V3 before approaching the other vehicle V2, or it is decelerated and waits for the oncoming vehicle V3 to pass, and after passing the oncoming vehicle V3, the passing completion position PE3 is included. You may pass through the area. By decelerating the own vehicle V1 in the vicinity of the passing completion positions PE2 and PE3, it is possible to execute traveling control with high safety.

As shown in FIG. 4A, for the target area R2 of the parked other vehicle V2, the distance L1 from the front end of the avoidance target V2 to the first end RL1 of the target area R2, the depth of the avoidance target V2 A minimum value may be set for the distance L2 from the end on the side to the second end RL2 of the target region R0, and a smaller value may not be set. A minimum value may be set for the horizontal width W0 of the target region R2, and a smaller value may not be set. The minimum value may be set for the distance L13 from the front end of the oncoming vehicle V3 to the first end RL1 of the target area R3 and the width W3 of the target area R3, and the minimum value may not be set.

Subsequently, the path setting function of the control device 10 will be described. The control device 10 of the present embodiment calculates the target route RT based on the set boundary position of the target region R0 and controls the distance between the host vehicle V1 and the avoidance target. Here, the method of “calculating the target route RT based on the position of the target region R0” is not limited. The control device 10 may calculate the target route RT so that the host vehicle V1 does not enter the target region R0, and the overlapping area between the target region R0 and the existing region of the host vehicle V1 is less than a predetermined value. Alternatively, the target route RT may be calculated, a position separated from the boundary line of the target region R0 by a predetermined distance may be calculated as the target route RT, or the boundary line of the target region R0 may be calculated as the target route RT. May be. As described above, the target region R0 is set so that the distance between the host vehicle V1 and the avoidance target does not become less than a predetermined value, or the distance between the host vehicle V1 and the avoidance target is maintained at a predetermined threshold. The For this reason, the target route RT is also set at a position where the distance between the host vehicle V1 and the avoidance target is not less than a predetermined value, or at a position where the distance between the host vehicle V1 and the avoidance target is maintained at a predetermined threshold.

The control function of the control device 10 will be described. The control device 10 of the present embodiment outputs control information for causing the host vehicle V1 to travel on the target route RT to the vehicle controller 70, the drive device 80, and the steering device 90 on the vehicle side.

The vehicle controller 70 of the present embodiment that has acquired the control information from the control device 10 controls the drive device 80 and the steering device 90 to drive the host vehicle V1 along the target route RT. The vehicle controller 70 uses the road shape detected by the detection device 50 and the lane marker model stored in the road information 122 and the map information 123 of the navigation device 120 to maintain the vehicle in a predetermined lateral position with respect to the lane. The steering device 90 is controlled to travel while traveling. The vehicle controller 70 calculates a steering control amount (turning control amount) based on the steering angle acquired from the steering angle sensor 61, the vehicle speed acquired from the vehicle speed sensor 62, and the current of the steering actuator, and a current is supplied to the steering actuator. By sending a command, control is performed so that the host vehicle travels in the target lateral position. In addition, as a method for controlling the lateral position of the host vehicle V1, in addition to using the steering device 90 described above, the driving direction of the host vehicle V1 is determined by the difference in rotational speed between the left and right drive wheels using the driving device 80 and / or the braking device 81. (That is, the lateral position) may be controlled. In that sense, the “turning” of the vehicle includes not only the case of using the steering device 90 but also the case of using the driving device 80 and / or the braking device 81.

Finally, the presentation function of the control device 10 of this embodiment will be described. The control device 10 calculates the information according to the target information, the information according to the position of the target region R, the information according to the position of the target route, and the information according to the control information for causing the host vehicle to travel on the target route. Is output to the output device 110 and output to the outside in the manner described above.

Subsequently, a control procedure of the travel control apparatus 100 of the present embodiment will be described based on the flowcharts of FIGS. 5 and 6. In addition, since the content of the process in each step is as above-mentioned, it demonstrates centering on the flow of a process here.

First, the overall procedure of travel control will be described with reference to FIG.

In step S101, the control device 10 acquires host vehicle information including at least the position of the host vehicle V1. The own vehicle information may include the vehicle speed and acceleration of the own vehicle V1. In step S102, the control device 10 acquires target information including a position to be avoided that the host vehicle V1 should avoid. The target information may include speed / acceleration to be avoided.

In step S103, the control device 10 acquires the detection result of the avoidance target from the detection device 50. The detection result of the avoidance target includes information on the position of the avoidance target. In step S104, the control device 10 sets the target region R according to the position to be avoided. The subroutine for the target area R setting process will be described with reference to FIG.

In step S105, the control device 10 calculates the target route RT based on the position of the boundary of the target region R. The target route RT includes one or a plurality of target coordinates on which the host vehicle V1 travels. Each target coordinate includes a target horizontal position (target X coordinate) and a target vertical position (target Y coordinate). The target route RT is obtained by connecting the calculated one or more target coordinates and the current position of the host vehicle V1. The method for calculating the target coordinates shown in step S105 will be described later.

In step 106, the control device 10 acquires the target lateral position of the target coordinates calculated in step S105. In step S107, the control device 10 calculates a feedback gain related to the lateral position based on the comparison result between the current lateral position of the host vehicle V1 and the target lateral position acquired in step S106.

In step S108, the control device 10 moves the target lateral position to the host vehicle V1 based on the actual lateral position of the host vehicle V1, the target lateral position corresponding to the current position, and the feedback gain in step S107. A target control value relating to the turning angle, turning angular velocity, etc. necessary for the movement is calculated. In step S112, the control device 10 outputs the target control value to the in-vehicle device 200. Thereby, the host vehicle V1 travels on the target route RT defined by the target lateral position. When a plurality of target coordinates are calculated in step S105, the processing of steps S106 to S112 is repeated each time the target lateral position is acquired, and the control value for each acquired target lateral position is transmitted to the in-vehicle device 200. Output.

In step S109, the control device 10 acquires a target vertical position for one or a plurality of target coordinates calculated in step S105. In step S110, the control device 10 determines the current vertical position of the host vehicle V1, the vehicle speed and acceleration / deceleration at the current position, the target vertical position corresponding to the current vertical position, and the vehicle speed and acceleration / deceleration at the target vertical position. Based on the comparison result, a feedback gain related to the vertical position is calculated. In step S111, the control device 10 calculates a target control value related to the vertical position based on the vehicle speed and acceleration / deceleration according to the target vertical position and the feedback gain of the vertical position calculated in step S110. The processing in steps S109 to S112 is repeated each time the target vertical position is acquired, similarly to steps S106 to S108 and S112 described above, and the control value for each of the acquired target horizontal positions is output to the in-vehicle device 200.

Here, the target control value in the vertical direction means the operation of a drive mechanism for realizing acceleration / deceleration and vehicle speed according to the target vertical position (in the case of an engine vehicle, the operation of an internal combustion engine, in the case of an electric vehicle system). This includes the electric motor operation, and in the case of a hybrid vehicle, also includes torque distribution between the internal combustion engine and the electric motor) and the brake operation control values. For example, in an engine vehicle, the control function calculates a target intake air amount (target opening of the throttle valve) and a target fuel injection amount based on the calculated values of the current and target acceleration / deceleration and vehicle speed. Then, this is sent to the driving device 80. The control function calculates the acceleration / deceleration and the vehicle speed, and sends them to the vehicle controller 70. The vehicle controller 70 operates the drive mechanism for realizing the acceleration / deceleration and the vehicle speed (in the case of an engine vehicle, an internal combustion engine). Control values for engine operation, electric motor operation in an electric vehicle system, and torque distribution between an internal combustion engine and an electric motor in a hybrid vehicle) and brake operation may be calculated.

And it progresses to step S112 and the control apparatus 10 outputs the target control value of the vertical direction calculated by step S111 to the vehicle-mounted apparatus 200. FIG. The vehicle controller 70 executes turn control and drive control, and causes the host vehicle to travel on the target route RT defined by the target lateral position and the target vertical position.

In step S113, the control device 10 causes the output device 110 to present information. The information to be presented to the output device 110 may be the position / velocity of the target area calculated in step S106, the shape of the target route calculated in steps S105 to S111, or in step S112. The target control value output to the in-vehicle device 200 may be used.

In step S114, it is determined whether or not the driver has performed a steering operation or the like, and whether or not the driver has intervened. If no driver operation is detected, the process returns to step S101 to repeat the setting of a new target area, calculation of the target route, and travel control. On the other hand, when the driver performs an operation, the process proceeds to step S115, and the traveling control is interrupted. In the next step S116, information indicating that the traveling control has been interrupted is presented.

Subsequently, the subroutine of the target area setting process (S104 in FIG. 5) of the travel control device 100 of the present embodiment will be described based on the flowchart of FIG.

After acquiring the host vehicle information and the target information (step S103), in step S201, the control device 10 performs a step when an avoidance target (such as another parked vehicle) existing in the lane on which the host vehicle V1 travels is detected. The process proceeds to S202. In step S202, if an avoidance target (such as another vehicle that faces opposite) is detected in the opposite lane of the lane in which the host vehicle V1 is traveling, the process proceeds to step S203, and if not, the process proceeds to step S211.

Step S211 and subsequent steps are processing when there is an avoidance target in the traveling lane of the host vehicle V1. In step S211, the control device 10 sets the target area R according to the position of the avoidance target detected in the travel lane. In step S212, the control device 10 determines whether or not the host vehicle V1 can travel without entering the target region R in the travel lane.

If the distance obtained by subtracting the width of the target area R from the width of the travel lane is larger than the vehicle width of the host vehicle V1, the host vehicle V1 can travel in the travel lane without entering the target area R. In this case, the process proceeds to step S213, and the control device 10 calculates a route passing through the approximate center of the target region and the lane marker as the target route RT.

On the other hand, when the own vehicle V1 cannot travel in the travel lane without entering the target area R, the process proceeds to step S214. In step S214, it is determined whether it is possible to enter an adjacent traveling lane. Whether or not the vehicle can enter an adjacent traveling lane is determined based on road information 122 including information on whether or not the overtaking regulation is applied to the lane. If it is determined in step S214 that the host vehicle V1 can enter the adjacent travel lane, the process proceeds to step S215, and the target route RT is calculated. On the other hand, if the host vehicle V1 cannot enter the adjacent travel lane, the process proceeds to step S216, and the host vehicle V1 is decelerated or stopped.

Returning to step S202, if an avoidance target (an oncoming vehicle V3 that runs on the opposite side) that exists in the opposite lane is detected, the process proceeds to step 203. In step S <b> 203, the control device 10 calculates a passing start position and a passing completion position at predetermined intervals based on the own vehicle information and the target information. And the control apparatus 10 sets the object area | region R based on the own vehicle information and object information in a passing start position. Similarly, the target region R is set based on the own vehicle information and the target information at the passing completion position.

Specifically, taking the situation shown in FIG. 4A as an example, in step S204, the other vehicle V2 is avoided based on the own vehicle information and target information at the passing start position and / or the passing completion position with the passing other vehicle V2. The target area R is set. In step S205, a target region R that avoids the oncoming vehicle V3 is set based on the own vehicle information and the target information at the passing start position and / or the passing completion position with the oncoming vehicle V3 that passes by later.

In the present embodiment, the target region R is set based on the vehicle information and the target information at the passing start position and / or the passing completion position. The control device 10 automatically passes the other vehicle V2 while keeping the distance from the other vehicle V2 properly, and further passes the other vehicle V3 while keeping the distance from the left and right other vehicles V2 and the opposite vehicle V3 appropriately. The vehicle V1 is caused to travel. Accordingly, the host vehicle V1 can pass the avoidance target while maintaining an appropriate distance from the avoidance target.

As described above, when a plurality of avoidance targets are detected and the host vehicle V1 is sandwiched between two or more avoidance targets, the control device 10 uses the weighting coefficient to beside the target region R2. A distance d1 (d1 + d2) between the end portion and the host vehicle V may be set. As a result, the distance in the vehicle width direction between the target region R and the host vehicle V1 is stabilized, and the position of the target route RT calculated based on the boundary of the target region R is not shifted left and right.

As described above, the control device 10 sets the length L0 of the target region R2 according to the positions of the passing start point PS and the passing completion point PE. As a result, the positions of the first end RL1 and the second end RL2 of the target region R2 are adjusted according to the positions of the passing start point PS and the passing completion point PE. Therefore, the turning operation for avoiding the avoidance target is performed. The point to do can be set appropriately. Thereby, it is possible to set the target region R2 suitable for the situation at the passing start point PS and the passing completion point RE.

In addition, since step S204 and step S205 are the processes performed sequentially about the avoidance object close to the own vehicle V1, either one of the steps may be executed depending on the situation.

In subsequent step S206, the control device 10 starts the target route calculation process in step S105 of FIG. 5 based on the set target region R, and executes the processes in and after step S106.

Since the traveling control apparatus 100 according to the embodiment of the present invention is configured and operates as described above, the following effects can be obtained.

[1] The travel control device 100 of the present embodiment is positioned on the side of the host vehicle V1 as viewed from the host vehicle V1 in the left and right ends of the target region R as the relative speed of the vehicle width direction component with respect to the avoidance target increases. The target region R is set so that the distance between the horizontal end portion to be avoided and the avoidance target becomes long. Thus, when the host vehicle V1 approaches the other vehicle V2 at a high relative speed, the target route RT calculated based on the boundary position of the target region R is separated from the other vehicle V2, and the host vehicle V1 becomes the other vehicle V2. Don't get too close. Since the target region R is set in consideration of the relative speed of the vehicle width direction component, it is possible to suppress the target route RT from being changed during the execution of the travel control. That is, the turning amount, turning angle, vehicle speed, acceleration, and the like of the host vehicle are not suddenly changed.

[2] The travel control device 100 according to the present embodiment, as the distance along the vehicle width direction with respect to the avoidance target is shorter, of the left and right end portions of the target region R and the side end portion on the own vehicle side viewed from the own vehicle V1 and the avoidance. The target region R is set so that the distance to the target becomes long. By shifting the lateral end of the target region R toward the host vehicle V1, the position of the target route RT calculated based on the position of the boundary of the target region R can be separated from the avoidance target. Thereby, the own vehicle V1 does not approach the other vehicle V2 too much.

[3] According to the traveling control device 100 of the present embodiment, the higher the relative speed, the more the first end RL1 of the target region R is set to a position that is separated from the other vehicle V2 (avoidance target) toward the host vehicle V1. To do. Thereby, the turning point (turning start point) of the target route RT1 that avoids the target region R1 can be shifted to the host vehicle V1 side. As a result, the turning amount and turning speed at the turning start point can be lowered, and the target route for avoiding the other vehicle V2 can be formed with a gentle curve. Since the turning amount and turning speed of the host vehicle V1 can be controlled to be low, the occupant does not feel uncomfortable.

[4] According to the travel control device 100 of the present embodiment, the higher the relative speed, the second end portion RL2 of the target region R is separated from the other vehicle V2 (avoidance target) toward the traveling direction of the host vehicle V1. Set to the specified position. Thereby, the turning point (turning completion point: return point to the straight traveling state) of the target route RT1 that avoids the target region R1 can be shifted to the traveling direction side of the host vehicle V1. As a result, the turning amount and the turning speed at the turning completion point can be lowered, and the target route for avoiding the other vehicle V2 can be formed with a gentle curve. The turning amount and turning speed of the host vehicle V1 can be controlled to be low.

[5] According to the travel control apparatus 100 of the present embodiment, the relative position of the host vehicle V1 relative to the other vehicle V2 from the passing start position PS2 closest to the other vehicles V2 and V3 to be avoided to the passing completion position PE2. Alternatively, by setting the position RW1 of the lateral end of the target area R based on the relative position with the oncoming vehicle V3 from the passing start position PS2 to the passing completion position PE3, the target area R in consideration of the situation of overtaking or passing. Can be set. Further, even if the avoidance target is a moving body whose positional relationship changes every moment like the oncoming vehicle V3, an appropriate target region R can be set according to the positional relationship when actually passing each other.

[6] According to the travel control device 100 of the present embodiment, the target region R is based on the relative position of the own vehicle V1 with the other vehicles V2 and V3 at the passing start position PS2 and the passing start position PS3 that are closest to the avoidance target. By setting the position RW1 of the lateral end of the other vehicle, the other vehicles V2, V3 can be reliably avoided. In particular, when the avoidance target is a moving object such as the oncoming vehicle V3, the positional relationship between the host vehicle V1 and the oncoming vehicle V3 changes every moment, but the target according to the positional relationship when actually overtaking or passing each other. Region R can be set.

[7] According to the travel control device 100 of the present embodiment, the target region R is based on the relative position of the own vehicle V1 with the other vehicles V2 and V3 at the passing start position PS2 and the passing start position PS3 that are closest to the avoidance target. By setting the positions RL1 and RL3 of the first end, the other vehicles V2 and V3 can be reliably avoided. In particular, when the avoidance target is a moving object such as the oncoming vehicle V3, the positional relationship between the host vehicle V1 and the oncoming vehicle V3 changes every moment, but the target according to the positional relationship when actually overtaking or passing each other. Region R can be set.

[8] According to the travel control device 100 of the present embodiment, the own vehicle V1 passes from the passing start position PS2 closest to the other vehicles V2 and V3 to be avoided to the passing completion position PE2, passing from the passing start position PS3 to the passing completion position. By setting the position RL2 of the second end portion of the target area R based on the relative position with the other vehicles V2 and V3 up to PE3, the target area R3 can be set in consideration of the situation of overtaking or passing.

[9] According to the travel control device 100 of the present embodiment, the lateral end RW1 is the avoidance target for the avoidance target that is close to the host vehicle V1 and / or the avoidance target that has a large relative speed with the host vehicle V1. The target region R is set so as to be farther from the position. Thereby, it can suppress that the own vehicle V1 approaches an avoidance object too much. The risk when the host vehicle V1 approaches the avoidance target can be reduced.

[10] According to the traveling control device 100 of the present embodiment, by outputting information related to traveling control that avoids the target region R to the outside, the behavior of the own vehicle is notified in advance to passengers of the own vehicle and / or other vehicles. be able to. Thereby, the passenger | crew of the own vehicle and / or the passenger | crew of another vehicle can respond according to the behavior of the own vehicle.
