The automatic operation control unit 100 includes a first control unit 120 and a second control unit 140, for example. The first control unit 120 and the second control unit 140 are each realized by a processor (CPU) such as a CPU (Central Processing Unit) executing a program (software). Some or all of the functional units of the first control unit 120 and the second control unit 140 described below are LSI (Large Scale Integration), ASIC (Application Specific Specific Integrated Circuit), FPGA (Field-Programmable Gate Gate Array). ) Or the like, or may be realized by cooperation of software and hardware.

The 1st control part 120 is provided with the external world recognition part 121, the own vehicle position recognition part 122, and the action plan production | generation part 123, for example.

Based on information input from the camera 10, the radar device 12, the finder 14, and the sound collection device 15 via the object recognition device 16, the external recognition unit 121 detects the position of the surrounding vehicle and the speed, acceleration, voice, and the like.

The position of the surrounding vehicle may be represented by a representative point such as the center of gravity or corner of the surrounding vehicle, or may be represented by an area expressed by the outline of the surrounding vehicle. The “state” of the surrounding vehicle may include acceleration and jerk of the surrounding vehicle, or “behavioral state” (for example, whether or not the lane is changed or is about to be changed). In addition to the surrounding vehicles, the external environment recognition unit 121 may recognize the positions of guardrails, utility poles, parked vehicles, pedestrians, and other objects.

When the camera 10, the radar device 12, the finder 14, and the sound collection device 15 acquire the rear information, the external recognition unit 121 recognizes a rear object based on information input via the body recognition device 16. .

And a control unit (output control unit) 121B. The rolling operation determination unit 121A and the HMI control unit 121B will be described in detail below.

The own vehicle position recognition unit 122 recognizes, for example, the lane (traveling lane) in which the host vehicle M is traveling, and the relative position and posture of the host vehicle M with respect to the traveling lane. The own vehicle position recognition unit 122, for example, includes a road marking line pattern (for example, an arrangement of solid lines and broken lines) obtained from the second map information 62 and an area around the own vehicle M recognized from an image captured by the camera 10. The traveling lane is recognized by comparing the road marking line pattern. In this recognition, the position of the host vehicle M acquired from the navigation device 50 and the processing result by INS may be taken into account.

And the own vehicle position recognition unit 122 recognizes the position and posture of the own vehicle M with respect to the traveling lane, for example. FIG. 2 is a diagram illustrating a state in which the vehicle position recognition unit 122 recognizes the relative position and posture of the vehicle M with respect to the travel lane L1. The own vehicle position recognizing unit 122 makes, for example, a line connecting the deviation OS of the reference point (for example, the center of gravity) of the own vehicle M from the travel lane center CL and the travel lane center CL in the traveling direction of the own vehicle M. The angle θ is recognized as the relative position and posture of the host vehicle M with respect to the traveling lane L1. Instead, the host vehicle position recognition unit 122 recognizes the position of the reference point of the host vehicle M with respect to any side end of the host lane L1 as the relative position of the host vehicle M with respect to the traveling lane. Also good. The relative position of the host vehicle M recognized by the host vehicle position recognition unit 122 is provided to the recommended lane determination unit 61 and the action plan generation unit 123.

The action plan generation unit 123 determines events to be sequentially executed in the automatic driving so that the recommended lane determination unit 61 determines the recommended lane and travels along the recommended lane, and can cope with the surrounding situation of the host vehicle M. Events include, for example, a constant speed event that travels in the same lane at a constant speed, a follow-up event that follows the preceding vehicle, a lane change event, a merge event, a branch event, an emergency stop event, and automatic driving There are a handover event for switching to manual driving, a rolling response event for responding to the rolling operation of the following vehicle, and the like. Further, during execution of these events, actions for avoidance may be planned based on the surrounding situation of the host vehicle M (the presence of surrounding vehicles and pedestrians, lane narrowing due to road construction, etc.).

The action plan generation unit 123 generates a target track on which the vehicle M will travel in the future. The target track is expressed as a sequence of points (track points) that the host vehicle M should reach. The trajectory point is a point where the host vehicle M should reach for each predetermined travel distance. Separately, the target speed and target acceleration for each predetermined sampling time (for example, about 0 comma [sec]) are the target trajectory. Generated as part of. Further, the track point may be a position to which the host vehicle M should arrive at the sampling time for each predetermined sampling time. In this case, information on the target speed and target acceleration is expressed by the interval between the trajectory points.

3 and 4 are diagrams showing how recommended lanes are selected based on the target track. As shown in the figure, the recommended lane is set so as to be convenient for traveling along the route to the destination. The action plan generation unit 123 activates a lane change event, a branch event, a merge event, or the like when a predetermined distance before the recommended lane switching point (may be determined according to the type of event) is reached. If it becomes necessary to avoid an obstacle during the execution of each event, an avoidance trajectory is generated as shown in the figure. Similarly, when it becomes necessary to deal with the rolling operation of the following vehicle during the execution of each event, the avoidance action corresponding to the situation is performed by activating the turning event as described later.

The action plan generation unit 123 generates, for example, a plurality of target trajectory candidates, and selects an optimal target trajectory at that time based on the viewpoints of safety and efficiency.

The second control unit 140 includes a travel control unit 141. The travel control unit 141 controls the travel driving force output device 200, the brake device 210, and the steering device 220 so that the host vehicle M passes the target track generated by the action plan generation unit 123 at a scheduled time. To do.

The driving force output device 200 outputs a driving force (torque) for driving the vehicle to driving wheels. The travel driving force output device 200 includes, for example, a combination of an internal combustion engine, an electric motor, a transmission, and the like, and an ECU that controls these. The ECU controls the above-described configuration in accordance with information input from the travel control unit 141 or information input from the driving operator 80.

The brake device 210 includes, for example, a brake caliper, a cylinder that transmits hydraulic pressure to the brake caliper, an electric motor that generates hydraulic pressure in the cylinder, and a brake ECU. The brake ECU controls the electric motor in accordance with the information input from the travel control unit 141 or the information input from the driving operation element 80 so that the brake torque corresponding to the braking operation is output to each wheel. The brake device 210 may include, as a backup, a mechanism that transmits the hydraulic pressure generated by operating the brake pedal included in the driving operation element 80 to the cylinder via the master cylinder. The brake device 210 is not limited to the configuration described above, and is an electronically controlled hydraulic brake device that controls the actuator according to information input from the travel control unit 141 and transmits the hydraulic pressure of the master cylinder to the cylinder. May be.

The steering device 220 includes, for example, a steering ECU and an electric motor. For example, the electric motor changes the direction of the steered wheels by applying a force to a rack and pinion mechanism. The steering ECU drives the electric motor according to the information input from the travel control unit 141 or the information input from the driving operator 80, and changes the direction of the steered wheels.

Next, an example in which a target track is set by the action plan generation unit 123 and a recommended lane and an alternative lane are selected will be described. An alternative lane is a lane that can be temporarily set to the target track by the action plan generator 123. The action plan generator 123 sets a target track and selects in principle the recommended lane (see FIG. 3). The action plan generator 123 sets a target trajectory according to the following conditions. Note that the following conditions are examples, and some of the conditions may be omitted, or further conditions may be added.

(1) When there are a plurality of candidate lanes for setting a target track, the action plan generation unit 123 sets the target track in the lane on the leftmost side (the rightmost in the case of right-hand traffic) with respect to the traveling direction of the host vehicle M. Set and select the recommended lane. That is, the action plan generation unit 123 selects a lane so as not to travel on the overtaking lane in principle. An overtaking lane is a lane that is set on the right side of a traveling lane in the case of left-hand traffic on a road with a plurality of lanes.

(2) The action plan generation unit 123 sets the target track to a lane other than the traveling lane when the traveling lane decreases or branches within a predetermined distance (for example, 2 km) in front of the host vehicle M. And select the recommended lane. That is, the action plan generation unit 123 selects a recommended lane so that the lane change is performed in advance if the lane change is necessary if the host vehicle M continues to travel in the traveling lane.

(3) When the destination direction is the branch destination lane at the branch point of the lane, the action plan generation unit 123 is the destination lane or the branch destination at a point a predetermined distance (for example, 1 km) before the branch point. The recommended lane is selected with the lane adjacent to the target lane as the target track. That is, the action plan generation unit 123 sets a target track in a branch destination lane or a lane adjacent to the branch destination lane and selects a recommended lane so that the lane change is easily performed when the lane change is necessary.

(4) At the junction point of the lane, set the main line as the target track at a point where the branch line can join the main line. That is, the action plan generator 123 sets a target track so as to merge with the main line at the merge point, and selects a recommended lane.

In accordance with the above conditions, the action plan generation unit 123 sets the target track on the recommended lane, sets a new target track on the lane adjacent to the recommended lane, and sets the target lane from the recommended lane having the set target track. In some cases, a new target track is set in a lane that separates one or more lanes.

In addition, the action plan generation unit 123 may temporarily change the lane according to the situation around the host vehicle M. Hereinafter, other lanes temporarily set to the target track from the recommended lane are referred to as alternative lanes. The action plan generation unit 123 may set a plurality of event candidates for the section in which the alternative lane is set. Then, the action plan generation unit 123 selects one event based on the situation of surrounding vehicles recognized by the object recognition device 16 and the presence or absence of an object such as an obstacle from among a plurality of event candidates set for this section. Select an event.

The action plan generation unit 123 selects a timely event from among these candidates according to the surrounding situation based on the recognition result by the object recognition device 16, and dynamically changes the action plan. For example, when a low-speed vehicle or an obstacle is found ahead while traveling in the recommended lane, the action plan generation unit 123 selects a lane change event and sets the adjacent overtaking lane as an alternative lane.

The action plan generation unit 123 changes the action plan so as to change the lane to the recommended lane after avoiding or overtaking an obstacle or a low-speed vehicle after changing the lane from the recommended lane to the alternative lane (see FIG. 4). The alternative lane is often an overtaking lane. When the alternative lane is traveling, the following vehicle mO traveling at a high speed from behind may approach the host vehicle M in some cases. Among the following vehicles mO, there is a vehicle that performs a so-called rolling operation that continuously travels with a close distance even when the host vehicle M is traveling at a legal speed, and displays an intention to go ahead.

The action plan generation unit 123 activates a turn-response event corresponding to a turn-over operation when the following vehicle mO approaches and makes a turn-drive while the host vehicle M is traveling in an alternative lane. The action plan generator 123 performs an avoidance action according to the hitting event. The whirling operation is determined by the whirling operation determination unit 121A. The whirling driving determination unit 121A determines whether or not the whirling driving (rapid approach) has occurred based on the monitoring result of the succeeding rear vehicle among the recognition results of the object recognition device 16.

FIG. 5 is a diagram for explaining the state of the rolling operation of the following vehicle. For example, while the host vehicle M is traveling, the rolling operation refers to a state in which the following vehicle is following the vehicle after a predetermined time has passed since the vehicle is closed. For example, the host vehicle M may be traveling with a lane change to an alternative lane adjacent to the recommended lane due to the occurrence of some event. At this time, the following vehicle mO may approach the host vehicle M and continue to travel with a close distance.

Based on the rear monitoring result of the object recognition device 16, the rolling driving determination unit 121 </ b> A has an inter-vehicle distance between the host vehicle M and the following vehicle mO equal to or smaller than a predetermined distance R, and the inter-vehicle distance is When the state where the distance is equal to or less than the distance R is continued for a predetermined time, it is determined that the rolling operation has occurred. The overturning driving determination unit 121A may determine that overturning driving has occurred when the distance between the vehicles changes at least one of a predetermined change amount or a change rate and an approach occurs. That is, 121A of driving | running | working driving | operations determine with the driving | running | working driving | operation having generate | occur | produced, when the temporal change of the threshold value of the distance between vehicles changes more than predetermined.

In addition, the spear driving determination unit 121A recognizes object behavior such as a passing light, a behavior that moves left and right, blinker lighting, use of a horn, a large muffler volume, and a following vehicle mO that performs a spear driving such as a vehicle type. You may detect from the apparatus 16 and you may use for the determination element of a rolling operation. When it is determined that the rolling operation has occurred, the HMI control unit 121B controls the HMI 30 in conjunction with the determination of the rolling operation of the driving determination unit 122, and displays an image display IM indicating that the rolling operation has occurred in the HMI 30. You may make it output and notify a driver | operator.

FIG. 6 is a diagram illustrating an example of the image IM output to the HMI 30. For example, an image for prompting attention such as “the vehicle is approaching rapidly from behind and the lane is changed” is displayed on the HMI 30. With this display, it is possible to alert the driver that the vehicle M is driving while the host vehicle M is driving automatically.

The action plan generation unit 123 executes a hit response event based on the determination of the occurrence of the hit operation by the hit operation determination unit 121A. The action plan generation unit 123 sets the recommended lane as the target track from the alternative lane in which the host vehicle M is currently traveling due to the turn event. The action plan generation unit 123 causes the travel control unit 141 to perform an avoidance action based on the determination of the occurrence of the rolling operation by the driving operation determination unit 121A. For example, the action plan generation unit 123 causes the travel control unit 141 to change the lane from an alternative lane in which the host vehicle M is currently traveling to a recommended lane.

Thereby, the vehicle system 1 can precede the succeeding vehicle mO performing the rolling operation. When other vehicles are traveling in the recommended lane to be changed and the lane cannot be changed safely, the action plan generator 123 delays or cancels the lane change until the lane can be changed safely. You may change to

FIG. 7 is a flowchart showing a process for determining the rolling operation. The whirling driving determination unit 121A determines whether or not the following vehicle mO has approached and the inter-vehicle distance has become equal to or less than a threshold value (step S10). When the inter-vehicle distance with the succeeding vehicle mO is equal to or less than the threshold value (step S10: Yes), the spear driving determination unit 121A determines whether or not the time that is equal to or less than the threshold value has continued for a predetermined time (step S11). ).

When the time that has become equal to or less than the threshold value continues for a predetermined time (step S11: Yes), the whirling driving determination unit 121A determines that the following vehicle mO performs the whirling operation (step S12). The action plan generation unit 123 executes the driving operation event and causes the travel control unit 141 to perform an avoidance action (step S13). When it becomes negative determination by step S10, S11, 121 A of spear driving | running determination parts continue the determination of a spear driving | running | working continuously.

The avoidance action for the drunken driving may be provided with a plurality of patterns depending on the state in which the host vehicle M travels in addition to the above lane change. The whirling driving determination unit 121A performs the whirling driving determination when the average speed of the host vehicle M is equal to or higher than a predetermined threshold, and does not perform the whirling driving determination when the average speed is lower than the predetermined threshold. You may do it. For example, when the host vehicle M is traveling at a predetermined speed or less that is set in advance, the driving operation determination unit 121A may not determine whether the driving operation has occurred. Thereby, for example, when the host vehicle M is traveling at a low speed during a traffic jam, it is possible to prevent the driving operation determination unit 121A from erroneously determining that the following vehicle mO is a vehicle driving in the driving state.

In addition, when the own vehicle M is traveling in the lane below the statutory speed, when the rolling driving determination unit 121A determines the occurrence of the rolling operation, the action plan generation unit 123 exceeds the legal speed of the own vehicle M. You may raise in the range which does not exist (refer FIG. 5). For example, the driver may set the cruise control to 80 km / h while traveling in a section where the speed is limited to 80 km / h. Thereafter, the speed limit is released and the host vehicle M may travel in a speed limit section of 100 km / h.

In this situation, if the speed of the own vehicle M is increased within a range not exceeding the statutory speed when it is determined that the following vehicle mO is driven in the speed limit section of 100 km / h, the own vehicle M and the following vehicle The inter-vehicle distance with mO can be increased. The action plan generation unit 123 controls the traveling control unit 141 to increase the speed of the host vehicle M within a range not exceeding the legal speed. Thereby, the inter-vehicle distance between the following vehicle mO and the host vehicle M can be kept larger than the threshold value. However, increasing the speed is limited to a case where a sufficient distance from the vehicle traveling ahead is ensured. At this time, the HMI control unit 121B may control the HMI 30 in conjunction with the determination of the rolling operation of the driving determination unit 122 to notify the driver to increase the speed. At this time, the HMI control unit 121B may control the HMI 30 to output an image display IM such as Yes / No that allows the driver to select to increase the speed.

Further, when the own vehicle M is traveling in the alternative lane, when the alternative lane is changed to the recommended lane within a predetermined distance or within a predetermined time, the action plan generating unit 123 causes the own vehicle to maintain the alternative lane. You may run M. FIG. 8 is a diagram illustrating an example in which an alternative lane is changed to a recommended lane. As shown in the figure, when the host vehicle M is traveling in the alternative lane as it is, the alternative lane may be changed to the recommended lane in order to change the lane to the branch lane.

In this state, when it is determined that there is a rolling operation by the driving operation determination unit 121A while traveling in the alternative lane, the action plan generation unit 123 sets the action plan so that the host vehicle M travels as it is in the alternative lane. Good. That is, the action plan generation unit 123 sets a new target track that travels as it is in the alternative lane. Thereby, it can suppress that the own vehicle M changes a lane frequently. In this case, the determination of the spear driving determination unit 121A may be stopped at a predetermined time.

When the host vehicle M is traveling on an alternative lane in a road having a plurality of lanes, the action plan generation unit 123 travels the alternative lane on which the host vehicle M is traveling at a predetermined time. You may let them. FIG. 9 is a diagram illustrating an example in which a rolling operation occurs when traveling in the center lane of three lanes. When the host vehicle M is traveling in an alternative lane in the center of the three lanes, an overtaking lane (alternate lane) adjacent to the alternative lane may be vacant. In this state, when it is determined by the driving operation determining unit 121A that there is a driving operation, the action plan generating unit 123 sets the action plan so as to maintain the traveling alternative lane for a predetermined time. Good.

As shown in the figure, for example, when it is determined that the vehicle M is running while driving on the central traffic zone of a three-lane road, the following vehicle mO is adjacent to the rightmost side (leftmost in the case of right-hand traffic). It is expected to overtake by changing lanes to the overtaking lane. For this reason, it is expected that the running operation will be eliminated even if the vehicle travels in the central traffic zone. Thereby, it can suppress that the own vehicle M changes a lane frequently.

As described above, according to the vehicle system 1, when the following vehicle mO approaches while the host vehicle M is traveling in the alternative lane, it is determined whether or not the following vehicle mO is driving and avoiding behavior. It can be performed. The vehicle system 1 can perform avoidance actions such as lane change, speed adjustment, action plan change, and the like on the following vehicle mO that is performing a scooping operation.

As mentioned above, although the form for implementing this invention was demonstrated using embodiment, this invention is not limited to such embodiment at all, In the range which does not deviate from the summary of this invention, various deformation | transformation and substitution Can be added.
