Description

Driving support system

The present invention relates to a technology that supports safe driving of a moving body such as a vehicle, and more particularly to a technology that is effective when applied to a driving support system that supports a driver to perform an appropriate driving operation.

In vehicles such as automobiles, with the expansion and evolution of the application of IT technology, a mechanism for automatically preventing accidents and ensuring safety during vehicle operation has been studied and started to be applied. For example, a technique for assisting safe driving by detecting dangerous driving or a state of a driver who drives a vehicle and issuing a warning or notification or controlling the vehicle has been studied.

As a technology related to this, for example, in Japanese Patent Application Laid-Open No. 2011-242190 (Patent Document 1), a driver's biometric information generated based on information collected during driving of a driver in the past is in a normal state. Acquired by the biometric information acquisition unit when the hazard map storage unit storing the hazard map in which the location changed from is stored and the vehicle position acquired by the position acquisition unit is the location recorded in the hazard map If there is no predetermined change in the driver's real-time biometric information, a dangerous state determination unit that determines that the driver's state is dangerous, and a driver that determines that the driver's state is dangerous A driving support device having a warning unit that issues a warning for alerting is described.

Further, for example, in JP 2009-29343 A (Patent Document 2), sensor values of a wheel speed sensor, a yaw rate sensor, and a brake pressure sensor that operate the preventive safety device or activate the preventive safety device are set in advance. If the threshold is exceeded, the driving location such as slopes, paved roads, curves, parking lots, intersections, the driving environment such as absolute time, snowfall information, rainfall information, outside temperature, and vehicle status such as vehicle speed Is stored in the storage unit in the vehicle terminal, and when the vehicle is about to travel in the stored driving environment and in the vehicle state, the vehicle is safely driven by warning notification to the driver or vehicle deceleration control. An in-vehicle terminal device that performs support is described.

In addition, for example, Japanese translations of PCT publication No. 2013-514593 (Patent Document 3) includes a line-of-sight detector that receives a line-of-sight vector from a driver, and a proximity sensor that detects the positions and speeds of a plurality of nearby objects. The vehicle accident risk is determined based on the position and speed of the other object, and the driver's recognition of the situation around the vehicle is determined based on the gaze position in addition to the position and speed of the nearby object. A technique for triggering a vehicle alarm in response to recognition and vehicle accident risk is described.

In addition, there is also a technique for providing driving safety including accident prevention between these vehicles by providing information related to driving support in each vehicle to other vehicles by inter-vehicle communication using short-range wireless communication or the like. It is being considered. For example, in Japanese Patent Laid-Open No. 5-266399 (Patent Document 4), the means for receiving information from other vehicles existing ahead, the result of processing the information of the preceding vehicle and the own vehicle, A traveling control device by inter-vehicle communication is described which includes means for transmitting to a vehicle and traveling information processing means connected to various controllers existing in the host vehicle.

JP 2011-242190 A JP 2009-29343 A Special table 2013-14592 gazette JP-A-5-266399

By using techniques such as those described in each of the above-mentioned patent documents, for example, depending on the position of the vehicle, the driving situation, the situation of the driver, the external environment, information obtained from other vehicles, etc. It is possible to estimate the degree and take measures such as warning and vehicle control as necessary.

However, with these technologies, the risk and degree of danger of an accident are determined and calculated based on various information obtained at each point in time, and a warning is taken into account. It is not a thing. In other words, depending on the situation, when driving, you can imagine not only the inner state of `` careful '' but also a series of driving operations that the driver should actually take, and if this is not followed The risk will increase greatly.

Accordingly, an object of the present invention is to provide a driving support system that grasps the actual driving situation and the content of the driving operation of the driver and performs safety confirmation and safe driving support based on this. is there.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

Of the inventions disclosed in this application, the outline of typical ones will be briefly described as follows.

A driving support system according to a typical embodiment of the present invention is a driving support system that supports the safe driving of a moving body by a driver, and has the following characteristics. That is, the moving body includes a moving body event acquisition unit that detects a moving body event that occurs for the entire moving body, an operation event acquisition unit that detects an operation event generated by the driving operation of the driver, Based on a combination of a moving body event and the operation event, a driver situation determination unit that determines whether the driver is in a situation where a predetermined series of actions should be performed, and a predetermined series of actions should be performed In a situation, whether the driver is performing the predetermined series of operations is monitored based on information acquired by an operation sensor that detects the driver's movements, and the driver An operation monitoring unit that notifies the driver of the fact when it is determined that the operation is not performed.

Among the inventions disclosed in the present application, effects obtained by typical ones will be briefly described as follows.

In other words, according to the representative embodiment of the present invention, the actual driving situation and the content of the driving operation of the driver are grasped, and based on this, the safety confirmation when driving the vehicle, support for safe driving, etc. are performed. It becomes possible.

It is the figure which showed the outline | summary about the structural example of the driving assistance system which is one embodiment of this invention. It is the flowchart which showed the outline | summary about the example of the flow of the process of the safety confirmation during driving | running | working of the vehicle in one Embodiment of this invention. It is the flowchart which showed the outline | summary about the other example of the flow of the process of the safety confirmation during driving | running | working of the vehicle in one Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that components having the same function are denoted by the same reference symbols throughout the drawings for describing the embodiment, and the repetitive description thereof will be omitted.

As described above, in recent years, when driving a vehicle such as an automobile, information obtained from various sensors mounted on the vehicle, CAN (Controller Area Network), etc., information obtained from other vehicles by inter-vehicle communication, a safe driving support system (DSSS: Driving Safety Support Systems) and other server systems, etc., based on information obtained via mobile communications, etc., in addition to the hazard level of the vehicle and the external environment, the driver's dangerous driving conditions Technologies that support safe driving by detecting and giving warnings and notifications or controlling vehicles are being studied.

Here, when driving the vehicle, the driver may be required to perform a predetermined action depending on the situation. For example, when making a right turn in an automobile, it is necessary to confirm the right and left safety in the order of “right, left, right”. If such a safety confirmation operation is leaked, the risk of occurrence of an accident increases. In addition, when the gear is put in the back, it is necessary to visually check the back of the vehicle or to check the back by looking at the rearview mirror or the vehicle monitor. Further, when another vehicle approaches the rear, it is necessary to check the rear vehicle by appropriately viewing the rearview mirror. As described above, a large number of predetermined operation patterns required in accordance with the situation can be assumed.

The predetermined operation as described above can be grasped mainly by the driver's line of sight. In recent years, eye tracking technology has progressed, and a viewpoint sensor (eye tracking sensor) can also be used at a relatively low cost.

Therefore, a driving support system according to an embodiment of the present invention is a system that supports safe driving of a vehicle such as an automobile, and when a specific event occurs or a specific state is detected in the vehicle. In addition, the driver's driving operation (in this embodiment, particularly the movement of the line of sight) is monitored and detected to determine whether the driver is performing a predetermined operation and to comply with a predetermined operation pattern. If not, a warning or the like is issued to prompt the user to perform a predetermined operation. This makes it possible to reduce the occurrence of accidents due to errors in artificial driving operations. Also, if the driver is performing the prescribed action correctly in a situation that requires caution, the caution can be omitted, and the situation where the driver is bothered by unnecessary warnings can be reduced. Is possible.

<System configuration>
FIG. 1 is a diagram showing an outline of a configuration example of a driving support system according to an embodiment of the present invention. The driving support system 1 includes, for example, an in-vehicle system 101 installed in each vehicle 100 such as an automobile. You may have the vehicle operation management system 200 which provides various services with respect to these vehicles 100. FIG. In this case, each vehicle 100 can access the vehicle operation management system 200 via the network 300 such as the Internet by mobile communication, for example.

The in-vehicle system 101 is configured by hardware or software including various microcomputers and devices installed in the vehicle 100, and includes, for example, the communication unit 110, the navigation system 120, the vehicle information sensor 130, the GPS 140, the viewpoint sensor 150, the driving. Each unit includes a support unit 160 and the like. Each of these units is configured to be able to transmit and receive information via, for example, a network such as CAN (not shown) or a signal line.

The communication unit 110 has a function of performing wireless communication with the outside of the vehicle 100. For example, the mobile communication function has a function of connecting to the network 300 via a mobile communication carrier. Moreover, you may have the function between vehicles which mutually communicates with the other vehicles 100 by the function of near field communication. The navigation system 120 is a car navigation system that is generally mounted on the vehicle 100. In addition to the navigation function to the destination, the navigation system 120 includes, for example, map information (not shown) and a current position obtained by the GPS 140 described later. Based on the information and the like, it has a function of outputting map-related information such as road and terrain characteristics.

The vehicle information sensor 130 is a sensor group that is installed in the vehicle 100 and acquires various information about the vehicle 100. For example, a peripheral object detection sensor that detects an obstacle around the vehicle 100 or another vehicle 100 that is approaching, a temperature sensor, an atmospheric pressure sensor, an acceleration sensor, or the like may be included. The GPS 140 is a GPS (Global Positioning System) sensor and has a function of acquiring information on latitude and longitude of the current position. It is desirable to be able to obtain advanced information. Other means may be used as long as the current position of the vehicle 100 (for example, a position on the xyz coordinate axis) can be acquired. The viewpoint sensor 150 is an eye tracking sensor having a function of tracking the driver's line of sight, and is installed on the dashboard of the vehicle 100, for example. It may be embedded in advance at a predetermined position of the vehicle.

The vehicle event acquisition unit 161 of the driving support unit 160 has a function of acquiring an event related to the vehicle 100 and appropriately updating information related to the status of the vehicle 100 held in the vehicle status 166 described later. The event related to the vehicle 100 is an event that is generated and detected for the entire vehicle 100. For example, an event indicating that another vehicle 100 or an obstacle is detected by the surrounding object detection sensor in the vehicle information sensor 130. Or, an instruction indicating that the road is a one-way road, general driving attention information such as a narrow road or a sharp curve, which is output by the navigation system 120, may be included.

The operation event acquisition unit 162 has a function of acquiring an event related to a driving operation by a driver of the vehicle 100 and appropriately updating information related to the status of the vehicle 100 held in a vehicle situation 166 described later. The event related to the driving operation is an event that is generated / detected when the driver performs the driving operation of the vehicle 100. For example, the event of stepping on the brake / accelerator, turning the steering wheel to the right / left, right / left It may include events such as taking out a blinker or putting it in back gear.

The map event acquisition unit 163 has a function of acquiring an event notified from the vehicle operation management system 200 via the communication unit 110. As will be described later, the vehicle operation management system 200 provides a service for managing the operation status of the vehicle 100 based on the information on the current position received from the vehicle 100 via the network 300. As one of the services, the vehicle operation management system 200 When any map event related to the current position of 100 is extracted, the map 100 has a function of responding to the vehicle 100 via the network 300. The in-vehicle system 101 periodically transmits, for example, information on the current position obtained by the GPS 140 and various types of information obtained by the vehicle information sensor 130 to the vehicle operation management system 200 via the communication unit 110.

A map event related to the current position is generated / detected when the vehicle 100 enters an area / road having attention information extracted based on operation information collected and accumulated from a large number of vehicles 100 in the vehicle operation management system 200. For example, it may include an event that occurs when the vehicle 100 enters a road with many accidents, a road with bad road surface conditions, a road with a dangerous curve, or the like. Note that the map event acquisition unit 163 is not an essential component and can be installed as an option.

The driver situation determination unit 164 is based on the status of the vehicle 100 held in the vehicle situation 166 and the event information acquired by each event acquisition unit (vehicle event acquisition unit 161 to map event acquisition unit 163). Has a function of determining whether or not a situation has arisen in which it is necessary to perform a predetermined operation. Whether there is a situation in which a predetermined operation needs to be performed may be determined based on a combination of statuses and events of the vehicle 100.

For example, if the left turn signal is detected when the accelerator is stepped on and the vehicle is traveling at a constant speed, it is a lane change while driving, and the driver checks the safety of the left lane. Determine that you are in a situation that needs to be done. Note that the situation in which the driver needs to perform a predetermined action is registered in advance in the line-of-sight definition 167 described later in association with the action (the movement of the line of sight in this embodiment) to be performed by the driver at that time. It shall be.

The line-of-sight monitoring unit 165 acquires and tracks the movement of the driver's line of sight by the viewpoint sensor 150 when the driver state determination unit 164 determines that the driver needs to perform a predetermined action. , And a function of monitoring whether or not the line-of-sight movement pattern registered in the line-of-sight definition 167 is observed. Whether or not the line of sight has seen a predetermined area (speedometer, rearview mirror, front left side of the vehicle 100, etc.) can be determined by the path of the coordinates of the line of sight and the staying time.

If the line-of-sight movement pattern is not observed, the driver is notified and warned that the risk of an accident is high. The notification or warning is transmitted to the vehicle operation management system 200 instead of or in addition to the driver, or when there is another vehicle 100 capable of inter-vehicle communication in the vicinity. It may be transmitted to the vehicle 100.

The vehicle status 166 is a data store that holds information related to the status of the vehicle 100 that changes based on the occurrence of an event related to the vehicle 100 or the like. For example, an ON / OFF flag or a numerical value for each item to be managed, such as whether the vehicle is traveling, whether the brake is stepped on, whether the steering wheel is turned off, whether the vehicle 100 exists in the vicinity, etc. Is held as a status. The vehicle situation 166 can be developed and held as a table on the memory, for example.

Also, the line-of-sight definition 167 holds information related to a situation in which the driver needs to perform a predetermined action and information related to an action to be performed by the driver at that time. For a situation where a predetermined action needs to be performed, for example, a status held in the vehicle situation 166 or a combination of events (when the left turn signal is issued while the accelerator is stepped on and traveling at a constant speed) The predetermined movement is defined as a line-of-sight movement pattern (viewing the rearview mirror and then viewing the left side of the vehicle 100, etc.).

The vehicle operation management system 200 collects and accumulates operation information of a plurality of vehicles 100 via the network 300, analyzes and analyzes various information related to operation of the vehicle 100, and various types obtained based on the results. This is a server system having a function of providing a service such as transmitting information to the vehicle 100 as information for operation. Such services are already generally available. The vehicle operation management system 200 includes, for example, a server device, a virtual server constructed on a cloud computing service, and the like, and is implemented by each unit such as the map event determination unit 210 implemented by software, a database, and the like. Each table includes operation accumulation information 220 and map information 230.

The operation accumulation information 220 is a table for accumulating information related to operations collected from each vehicle 100. For example, the contents are analyzed by a process such as an analysis unit (not shown) to extract a point where an accident is likely to occur or an area requiring attention for driving. The extracted contents are held in the map information 230.

As one of the services provided by the vehicle operation management system 200, the map event determination unit 210 extracts a map event related to the current position based on the information on the current position received from each vehicle 100, and extracts the map event. And has a function of transmitting to the vehicle 100 via the network 300. That is, based on the current position of the vehicle 100, it is determined whether or not there is a point or road that has a high possibility of occurrence of an accident registered in the map information 230 corresponding thereto, and if it exists, the information is extracted. And transmitted to the vehicle 100 as a map event. As described above, information on the current position acquired from the vehicle 100 can include information such as altitude and atmospheric pressure in addition to the two-dimensional information of latitude and longitude.

With the above configuration, when a specific event occurs in the vehicle 100 or when the driver needs to perform a predetermined action due to a transition to a specific status, the viewpoint sensor 150 causes the driver's The movement of the line of sight is tracked, and it is determined whether or not the movement pattern defined in the line-of-sight definition 167 is observed. Note that the line-of-sight definition 167 may be defined by a “region that should not be viewed” instead of the definition by the “region to be viewed”.

Further, the line-of-sight information may be stored in the operation accumulation information 220 by adding the line-of-sight movement history information to the operation information transmitted from the vehicle 100 to the vehicle operation management system 200. Thereby, for example, the relationship between the movement of the line of sight and the occurrence of an accident or danger can be analyzed, and the operation of improving the registered contents of the line of sight definition 167 based on the analysis result is also possible.

<Processing flow>
FIG. 2 is a flowchart showing an outline of an example of a flow of a safety confirmation process during traveling of the vehicle 100 in the driving support system 1 of the present embodiment. The driving support unit 160 of the in-vehicle system 101 first determines whether the event acquisition unit (vehicle event acquisition unit 161 to map event acquisition unit 163) has detected an event (S01). If no event is detected, the process of S01 is repeated until an event is detected.

If any event is detected in step S01, the corresponding status information in the vehicle situation 166 is updated according to the detected event (S02). Thereafter, the driver situation determination unit 164 searches the current vehicle situation 166 contents and whether or not the entry corresponding to the detected event is registered in the line-of-sight definition 167 (S03), and confirms whether or not it is registered. (S04). If the corresponding entry is not registered, the process returns to step S01 to repeat the event detection process.

When an entry is registered in the line-of-sight definition 167 in step S04, information on the movement pattern associated with the entry, that is, information on the line-of-sight movement pattern in the present embodiment is acquired, and processing is performed for each step of the pattern. Repeat loop processing is started (S05 to S09). In the loop process, first, the line-of-sight monitoring unit 165 acquires information on the line of sight acquired by the viewpoint sensor 150 (S06). The viewpoint sensor 150 may always record the line-of-sight information for a certain period of time, so that the line-of-sight information from a time point traced back for a certain period of time may be acquired.

Thereafter, it is determined whether or not the acquired movement of the line of sight complies with the operation content in the target step in the movement pattern of the line-of-sight definition 167 (S07), and the determination result is confirmed (S08). The operation content can be defined in a format such as “I should see this area” or “I should not see this area”. If the determination result in step S08 is OK, the process proceeds to the next step in the operation pattern of the line-of-sight definition 167, and loop processing is repeated (S09, S05). If the line-of-sight determination results at all steps in the operation pattern are OK, the loop process is terminated, and the process returns to step S01 to repeat the event detection process.

On the other hand, if the determination result is NG in step S08 during the loop process, the loop process is terminated, and notification is given that the movement of the line of sight does not comply with the predetermined operation pattern (S10). As a notification method, for example, an appropriate means such as voice output to the driver or display / projection of a warning message on the panel, windshield, or the like can be used. As described above, instead of or in addition to the notification to the driver, a notification is transmitted to the vehicle operation management system 200, or a notification is transmitted to other nearby vehicles 100 by inter-vehicle communication. You may do it. After the notification, the process returns to step S01 to repeat the event detection process.

By the above processing, it is possible to reduce the risk of human accidents by issuing a warning or the like when the driver does not comply with the operation pattern (gaze movement) required in a predetermined situation. In addition, when the operation pattern is observed, it is possible to reduce a situation in which the driving operation is troubled by an unnecessary warning or the like by not issuing a warning or the like.

FIG. 3 is a flowchart showing an outline of another example of the flow of the safety confirmation process during traveling of the vehicle 100 in the driving support system 1. Here, as a modification of the processing flow shown in FIG. 2, in addition to each processing shown in FIG. 2, a specific event has occurred in the vehicle 100 or a specific status has occurred. In a situation where it is necessary to perform an action, a process of guiding the driver is performed so that the action is performed according to the action pattern defined in the line-of-sight definition 167 (in this embodiment, the line of sight is moved). Thereby, the movement of the driver's line of sight can be made to effectively follow a predetermined pattern.

3 is the same as steps S01 to S05 in the processing flow of FIG. 2, and thus the description thereof will not be repeated. In the example of FIG. 3, in step S15, after starting a loop process that repeats the process for each step of the line-of-sight movement pattern, first, the line-of-sight monitoring unit 165 performs the operation content in the target step (“see this region. The driver's line of sight is instructed to be guided to the correct position and target (S16). As a notification method, for example, an appropriate means such as outputting a guidance message by voice or displaying / projecting a guidance image on a panel, a windshield, or the like can be used.

Thereafter, similarly to steps S06 to S08 in the processing flow of FIG. 2, the information on the line of sight acquired by the viewpoint sensor 150 is acquired (S17), and the operation content in the target step in the operation pattern of the line of sight definition 167 is observed. (S18), and the determination result is confirmed (S19). If the determination result is OK, the process proceeds to the next step in the operation pattern of the line-of-sight definition 167 as in step S09 of the processing flow of FIG. 2, and loop processing is repeated (S21, S15).

On the other hand, if the determination result in step S19 is NG, notification is made that the movement of the line of sight does not comply with the predetermined operation pattern, as in step S10 of the processing flow of FIG. 2 (S20). In the example of FIG. 3, unlike the example of FIG. 2, when non-compliance of the operation pattern is detected, the loop process is not terminated, and then the process proceeds to the next step in the operation pattern of the line-of-sight definition 167. The loop process, that is, the line-of-sight guidance process for the driver is continued (S21, S15). Whether or not to exit the loop process when detecting non-compliance with the motion pattern, that is, whether or not to continue the process related to the gaze guidance process or the monitoring of the motion pattern compliance is shown in FIG. None of the three processing flow examples is particularly limited, and appropriate means can be used as appropriate.

Through the above processing, the driver is guided to comply with the operation pattern required in a predetermined situation, so that the predetermined operation pattern can be effectively followed and the risk of human accidents can be reduced.

As mentioned above, the invention made by the present inventor has been specifically described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say. For example, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to the one having all the configurations described. In addition, it is possible to add, delete, and replace other configurations for a part of the configuration of the above-described embodiment.

For example, in the present embodiment, a vehicle is described as an example of a vehicle. However, the vehicle includes, for example, a private vehicle such as a truck or a bus, a vehicle other than a passenger vehicle, a railcar, and the like. In addition, the target is not limited to a vehicle, and can include general moving objects such as aircraft and ships that are driven and operated by a driver.

In addition, in this embodiment, whether or not the driver's movement is in compliance with the movement pattern is determined by acquiring the movement of the driver's line of sight with the viewpoint sensor. It is not limited to this. For example, the motion itself of the driver may be detected by a motion sensor.

The above-described configurations, functions, processing units, processing means, and the like may be realized by hardware by designing a part or all of them, for example, with an integrated circuit. Each of the above-described configurations, functions, and the like may be realized by software by interpreting and executing a program that realizes each function by the processor. Moreover, in each said figure, the control line and the information line have shown what is considered necessary for description, and do not necessarily show all the control lines and information lines on mounting. Actually, it may be considered that almost all the components are connected to each other.
