Description

Technical Field

[0001] The present invention relates to a danger avoidance system, an information processing device, a computer program, etc. in the door opening operation of a vehicle.

Background Art

[0002] When parking at a parking lot or on the roadside, an operation of opening the door occurs to get out of the vehicle. At that time, there is a problem that if there is a person or a vehicle passing near the vehicle at the timing of opening the door, a collision may occur. In particular, the rear seat door is often opened by children, and there is a problem that it is difficult to check for people from the rear of the vehicle using a side mirror or the like.

[0003] As a means for solving the above problems, in Patent Document 1, a system has been proposed that uses a camera or a sensor attached to a vehicle to detect a person or a vehicle from the rear of the vehicle and give a warning inside the vehicle or restrict the door opening operation.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When parking a vehicle at a parking lot or the like and getting out of the vehicle, be careful not to hit the parked vehicle next to it with the opened door. Also, when getting out of the driver's seat or the front passenger seat, check the side mirror, rear mirror, etc. to confirm whether a person or a vehicle is approaching from the rear.

[0006] However, even if a person sitting in the rear seat of a vehicle looks at the side mirror or rearview mirror, it is difficult to check for people or vehicles coming from behind. In this case, the person in the driver's seat or passenger seat may sometimes prompt the person in the rear seat, but it is quite possible that the warning may not come in time. As a result, an accident may occur where an opened door comes into contact with a person or vehicle coming from behind.

[0007] In Patent Document 1, when there is an approaching object from behind the vehicle, it is possible to avoid contact between an opened door and a person or vehicle coming from behind by giving a warning inside the vehicle and restricting the door opening operation. However, for example, even when a pedestrian is approaching slowly, if the person is approaching the vehicle, a warning or door opening operation restriction will be executed.

[0008] Then, even in a scene where the risk level is not high, a warning or the like is given, so as a user, the user gets used to the warning and the attention decreases. As a result, there is a possibility that an accident may occur where an opened door comes into contact with a person or vehicle coming from behind.

[0009] Therefore, an object of the present invention is to provide a risk avoidance system capable of giving a warning and restricting the door opening operation according to an object approaching from behind the own vehicle.

Means for Solving the Problem

[0010] A risk avoidance system according to one aspect of the present invention includes a rear image acquisition unit that acquires a rear image of the vehicle, an approaching object detection unit that detects the type of an object approaching from behind the vehicle, an approaching object speed detection unit that detects the speed of the object, a risk avoidance processing unit for executing at least one of a warning to an operator of the vehicle and a restriction on the door opening operation of the vehicle according to the type and speed of the object, and a door opening operation restriction mechanism for restricting the door opening operation, and is characterized by having the same.

Effect of the Invention

[0011] According to the present invention, it is possible to provide a danger avoidance system capable of warning and restricting the opening operation of a door according to an object approaching from behind the own vehicle.

Modes for Carrying Out the Invention

[0013] Hereinafter, embodiments of the present invention will be described using examples with reference to the drawings. However, the present invention is not limited to the following examples. In each figure, the same members or elements are denoted by the same reference numerals, and overlapping descriptions are omitted or simplified.

[0014] FIG. 1 is a functional block diagram showing a configuration example of a danger avoidance system 100 according to an embodiment of the present invention, and 110 is an information processing device. Note that some of the functional blocks shown in FIG. 1 are realized by causing a CPU or the like as a computer (not shown) included in the danger avoidance system 100 to execute a computer program stored in a memory as a storage medium (not shown).

[0015] However, some or all of them may be realized by hardware. As the hardware, a dedicated circuit (ASIC), a processor (reconfigurable processor, DSP), or the like can be used.

[0016] Also, each of the functional blocks shown in FIG. 1 does not have to be built in the same housing, and may be configured by separate devices connected to each other via a signal path. Further, the information processing device 110 does not have to be mounted on a vehicle, and may be mounted on an external control terminal.

[0017] In FIG. 1, a rear image acquisition unit 11 acquires a rear image from a rear imaging device 120 for imaging a rear image of the host vehicle (own vehicle). A surrounding image acquisition unit 12 acquires a surrounding image from a surrounding imaging device 130 for imaging an image around the vehicle.

[0018] The rear imaging device 120 and the surrounding imaging device 130 include an optical lens and an imaging element such as a CCD image sensor or a CMOS image sensor. The optical image of the subject captured by the optical lens is converted into an image signal by the imaging element, and analog-digital conversion, image adjustment processing, etc. are performed to generate image data.

[0019] FIG. 2 is a diagram showing an arrangement example of the rear imaging device 120 and the surrounding imaging device 130 according to an embodiment of the present invention. The rear imaging device 120 is arranged behind the host vehicle 10 as shown in FIG. 2 to acquire an image behind the host vehicle. Also, the surrounding imaging device 130 is arranged on the right side and the left side of the host vehicle as shown in FIG. 2 to acquire images on both sides of the host vehicle, respectively.

[0020] In the example shown in FIG. 2, the rear imaging device 120 is disposed near the back door, and the left and right peripheral image acquisition units 12 are respectively disposed at the positions of the left and right side mirrors. However, as long as images of the rear of the host vehicle and images of both sides can be acquired, they do not have to be at the positions shown in FIG. 2.

[0021] The danger avoidance system 100 receives the rear image captured by the rear imaging device 120 and acquired by the rear image acquisition unit 11 by the approaching object detection unit 101 and the approaching object speed detection unit 102. The approaching object detection unit 101 detects the presence or absence of an object approaching from the rear of the host vehicle (host vehicle) based on the rear image of the host vehicle, and also detects the type of the object.

[0022] In addition, the approaching object speed detection unit 102 detects the speed of the object detected by the approaching object detection unit 101. On the other hand, the both-side vehicle detection unit 103 receives the images of both sides captured by the surrounding imaging device 130 and acquired by the surrounding image acquisition unit 12, and detects whether there is another vehicle or the like in the vicinity of both sides of the host vehicle (for example, within 1 m).

[0023] The danger avoidance processing unit 104 receives the presence or absence of an object and its speed information behind the host vehicle from the approaching object detection unit 101 and the approaching object speed detection unit 102, and also receives information on whether there is another vehicle or the like in the vicinity of both sides of the host vehicle (for example, within 1 m) from the both-side vehicle detection unit 103.

[0024] The danger avoidance processing unit 104 includes a danger level acquisition unit 1041 and an approaching object path detection unit 1042. In the danger level acquisition unit 1041, the danger level of an object approaching from the rear of the host vehicle is acquired according to the type of the object and its speed.

[0025] Note that the danger level acquisition unit 1041 may acquire the danger level by calculating the danger level using a mathematical formula or the like, or may acquire the danger level by referring to a table. In addition, the approaching object path detection unit 1042 predicts the traveling path that an object approaching from the rear of the host vehicle will pass through.

[0026] When the vehicle door is opened and the door is on the path of an object behind the vehicle, according to the degree of danger, a warning is issued to the passengers in the vehicle or the opening operation of the door is restricted. The sound warning control unit 105 controls the voice output unit 13 based on the warning signal from the danger avoidance processing unit 104. Also, the door opening operation restriction unit 106 controls the door opening operation restriction mechanism 14 based on the opening operation restriction signal from the danger avoidance processing unit 104, for example, locks the door.

[0027] Here, the voice output unit 13 is a speaker or the like capable of outputting voice installed inside the vehicle, and outputs a warning sound or a voice such as "Please open the door while paying attention to objects coming from behind".

[0028] Also, the voice output unit 13 is not limited to the speaker installed inside the vehicle, and may be a device that notifies a character display or a voice warning to the passenger's smartphone or the like. Furthermore, since there is a possibility that the object approaching from behind is a vehicle capable of communicating via a network, a warning signal may be transmitted to the vehicle behind via the network to notify the vehicle behind of the warning. That is, the danger avoidance processing unit may, for example, transmit a warning to the vehicle behind when the door of the own vehicle is opened.

[0029] The door opening operation restriction mechanism 14 is a mechanism incorporating a plunger, a motor, etc. for restricting the opening operation of the door, and has a function of temporarily locking the door so that, for example, a child cannot open the door from inside the vehicle. Alternatively, instead of locking the opening operation of the door, the door opening operation restriction mechanism 14 may restrict the opening angle of the door to be smaller than the full open angle.

[0030] Figure 3 is a flowchart showing an example of a danger avoidance method by the danger avoidance system 100 in an embodiment of the present invention. The operations of each step of the flowchart in Figure 3 are sequentially performed by a CPU or the like as a computer in the danger avoidance system executing a computer program stored in a memory.

[0031] When the power of the vehicle is turned on, the flow in FIG. 3 starts. In step S1000, the CPU of the danger avoidance system determines whether it is in the automatic mode. Here, the automatic mode is a mode in which warnings and door opening operation restrictions are automatically performed according to the situation around the vehicle when the door of the vehicle is opened.

[0032] If it is determined as No in step S1000, the flow in FIG. 3 ends. That is, when the driver turns off the automatic mode, the execution of warnings and door opening operation restrictions is stopped. Thus, in this embodiment, the danger avoidance processing unit has an automatic mode in which at least one of warnings and door opening operation restrictions is automatically performed, and the user such as the driver can turn off the automatic mode.

[0033] If it is determined as Yes in step S1000, in step S1001, the CPU of the danger avoidance system determines whether the vehicle has stopped. If it is determined as No, it returns to step S1000.

[0034] If it is determined as Yes in step S1001, in step S1002, the CPU of the danger avoidance system determines whether an object is approaching from behind the vehicle based on the rear image of the vehicle acquired by the rear image acquisition unit 11 by the approaching object detection unit 101. If it is determined as No in step S1002, it returns to step S1000.

[0035] Here, for the side where it is detected by the both-side vehicle detection unit 103 that there is another vehicle or the like in the vicinity of the vehicle (for example, within 1 m), the possibility that a car, a motorcycle, or a bicycle passes through from behind is low. Therefore, when there is an object approaching and passing through from behind the vehicle, the object may be narrowed down to a pedestrian or the like. That is, the danger avoidance processing unit may determine the type of the object approaching from behind as a pedestrian when there are other objects in the vicinity of both sides of the vehicle (for example, within 1 m).

[0036] In step S1003, the CPU of the danger avoidance system detects whether the object approaching from behind the host vehicle is any one of an automobile, a motorcycle, a bicycle, a pedestrian, etc. Also, in step S1004, the CPU of the danger avoidance system detects the speed of the approaching object by the approaching object speed detection unit 102.

[0037] Next, in step S1005, the CPU of the danger avoidance system predicts the traveling route of the detected approaching object. An example of a specific prediction method will be described using the diagram showing the relationship between the host vehicle and the approaching object shown in FIG. 4. FIG. 4 is a diagram showing an example of the relationship between the host vehicle and the approaching object in an embodiment of the present invention.

[0038] In FIG. 4, the host vehicle is parked in a parking lot, and in addition, other vehicle A and other vehicle B are parked. An example is shown where another automobile approaches from the right rear of the host vehicle at 10 km / h as the approaching object 41. Also, a pedestrian approaches at 5 km / h from the left rear of the host vehicle and passes through between other vehicles 43 and 44 as the approaching object 42. Also, the state where the door of the host vehicle is open is shown by the △ display in the figure.

[0039] Next, in step S1006, when the CPU of the danger avoidance system opens the door of the host vehicle, it determines whether the traveling route of the approaching object overlaps with the door. For example, in FIG. 4, when the approaching object 41 approaches straight from the right rear, it will pass through the predicted traveling route 45, and there is a possibility of collision when the right door of the host vehicle is opened. On the other hand, when the approaching object 42 approaches straight, it will pass through the predicted traveling route 46, and there is a possibility of collision when the left door of the host vehicle is opened.

[0040] In such a case, it is determined as Yes in step S1006, and in step S1007, the CPU of the danger avoidance system calculates the degree of danger according to the speed of the detected approaching object and what the object is. When it is determined as No in step S1006, the process returns to step S1000.

[0041] FIG. 5 is a diagram showing an example of setting a risk level according to the type and speed of an object approaching from behind the vehicle in an embodiment of the present invention. The speed of the object is classified into high speed (20 km / h or more), medium speed (less than 20 km / h and 5 km / h or more), and low speed (less than 5 km / h). Further, for each of high speed, medium speed, and low speed, the object is further classified into those moved by power such as motors and engines of automobiles and motorcycles, those moved by human power such as bicycles, and pedestrians.

[0042] Then, a risk level is set for each of the further classifications, and the risk level is classified into three levels: high, medium, and low. For example, in the case of a high-speed (20 km / h or more) automobile, the risk level is set as "high" which is the maximum. On the other hand, in the case of a low-speed (less than 5 km / h) pedestrian, the risk level is set as "low".

[0043] In this way, the risk acquisition unit increases the risk level as the speed of the object approaching from behind increases. Also, when the type of the object approaching from behind is an automobile or a motorcycle, the risk level is set higher than that in the case of a human.

[0044] In the example shown in FIG. 4, since the approaching object 41 is an automobile at 10 km / h, according to the classification in FIG. 5, the risk level corresponds to "high". On the other hand, since the approaching object 42 is a pedestrian at 5 km / h, the risk level also corresponds to "medium". Next, in step S1008, the CPU of the risk avoidance system executes at least one of a warning and a restriction on the opening operation of the door according to the risk level of the approaching object.

[0045] That is, in steps S1007 and S1008, the risk avoidance processing unit 104 acquires a risk level according to the type and speed of the object, and executes at least one of a warning to the vehicle operator and a restriction on the opening operation of the vehicle door according to the risk level.

[0046] FIG. 6 is a diagram showing an example of warning and door control for each risk level in an embodiment of the present invention. As shown in FIG. 6, when the risk level is "high", a warning and door lock are performed. Also, when the risk level is "medium", only a warning is performed, and when the risk level is "low", nothing is done.

[0047] FIG. 7(A) is a timing chart showing an example of the timing of warning of the approaching object 41 and door opening operation restriction in an embodiment of the present invention, and (B) is a timing chart showing an example of the timing of warning of the approaching object 42.

[0048] In the chart of FIG. 7, the horizontal axis indicates time. At time t0, an approaching object is detected, at time t1, a warning is issued, and at time t2, the door opening operation is restricted. Time t3 indicates the predicted collision time, which is the timing of collision with the host vehicle.

[0049] In the example shown in FIG. 4, when another vehicle as the approaching object 41 enters the viewing angle of the rear imaging device 120 behind the host vehicle, the approaching object detection unit 101 can confirm the approaching object 41 when the distance between the other vehicle as the approaching object 41 and the door approaches 9 m.

[0050] On the other hand, in the example of FIG. 4, the approaching object 42 can be confirmed when the distance between the approaching object 42 and the door approaches 6 m. Considering their respective speeds, it takes 3.2 seconds for the approaching object 41 to travel 9 m, and it takes 4.3 seconds for the approaching object 42 to travel 6 m. That is, in FIG. 7(A), time t3 is 3.2 seconds, and in FIG. 7(B), time t3 is 4.3 seconds.

[0051] Here, the time t1, which is the timing for issuing a warning, and the time t2, which is the timing for executing the door opening operation restriction, are set in advance based on the time t3 until collision with the host vehicle. That is, the risk avoidance processing unit changes the timing for executing at least one of the warning and the door opening operation restriction according to the speed of the object approaching from behind.

[0052] Also, in this embodiment, the warning time is set 3 seconds before the predicted collision time t3, and the door opening operation restriction time is set 2 seconds before the predicted collision time t3. In that case, after the approaching object 41 is detected at t0, a warning is issued at t1, which is 0.2 seconds later. Further, the door opening operation is restricted at t2, which is 1 second after that.

[0053] That is, the danger avoidance processing unit sets the timing for executing at least one of warning and door opening operation restriction according to the predicted time of collision between the door and the object. Also, when executing warning and door opening operation restriction, the timing of warning and door opening operation restriction is set with a shift.

[0054] On the other hand, after the approaching object 42 is detected at t0, a warning is issued 1.3 seconds later. Since the approaching object 42 has a "medium" degree of danger, no door opening operation restriction is imposed. After executing the restriction in step S1008, the process returns to step S1000 again.

[0055] In addition, in this embodiment, in FIG. 4, an example when the own vehicle stops in a parking lot has been described. However, when the vehicle is stopped on the road shoulder etc. during driving and a passenger in the rear seat etc. gets off, by performing the same restriction, it is possible to prevent collision with a motorcycle, bicycle, person etc. from behind.

[0056] Also, in the case of driving on the left side, since it is common for the passenger to open the left door and get off, the right door may be locked so as to ignore the approach of other vehicles from the right rear of the own vehicle.

[0057] Furthermore, the driver may be able to arbitrarily set the speed of the object, the classification of the degree of danger, the timing for warning of collision, and the timing for controlling the door opening operation restriction.

[0058] As described above, in this embodiment, when the own vehicle is stopped and the passenger opens the door, if it is detected that an object is approaching from behind, the passenger is warned by voice or the door opening operation is restricted. Also, when the vehicle door is opened and it is determined that the door overlaps the traveling route of an object approaching from behind, at least one of warning and door opening operation restriction is executed. Therefore, it is possible to stably avoid an accident in which another vehicle collides with the door.

[0059] Also, in this embodiment, according to the type of approaching object from behind and its speed, by switching the presence or absence of warnings and door locks, more appropriate notifications can be made according to the need. Therefore, the vehicle occupants will not get used to the warnings and can pay attention.
