Description

Information processing system for vehicles

The present invention relates to a technical field of an information processing system for a vehicle that processes and provides various information input to the vehicle to a driver of the vehicle such as an automobile.

As this type of device, for example, in order to prevent a collision with a preceding vehicle, an obstacle, or the like, a warning is given to the driver when the risk of a collision increases. In such an apparatus, when a plurality of types of alarms are to be issued simultaneously, an alarm to be issued is selected based on a predetermined condition.

For example, Patent Documents 1 and 2 propose a technique in which risk points are comprehensively calculated from a driver state, an environmental state, and a vehicle state, and an alarm is issued based on the priority order. Patent Document 3 proposes a technique of integrating the risk level and urgency level of information to determine priority and transmitting it to the driver.

JP 2009-151648 A JP 2009-151649 A JP 2001-143191 A

For example, various information such as road guidance information by a car navigation system and advertisement information from a nearby store is input to the vehicle, for example, in addition to the urgent information that should issue an alarm. Therefore, the vehicle information processing system is required to appropriately select information to be output from a plurality of types of information.

In such a case, if information that should be alarmed is output with the highest priority, it may be possible to at least improve the effect of preventing a collision or the like. However, even if it is information that should issue a warning, it can be said that the risk is low when the distance to the object is large or the speed of the vehicle is low. On the other hand, for example, right turn and left turn guidance information at an intersection is less urgent in the sense of avoiding danger, but becomes information that does not make any sense if it passes through the target intersection. For this reason, there may arise a situation in which the guidance information should be output with priority over the information to be alerted.

On the other hand, for example, Cited Documents 1 and 2 deal only with information that should be alerted, so it is considered difficult to output other information appropriately. Moreover, in patent document 3, since the suitable parameter | index is not set in the process of various information, it is thought that there exists room for improvement in the judgment precision at the time of selecting information. As described above, the conventional techniques including Reference Documents 1 to 3 have a technical problem that information input to the vehicle cannot be appropriately processed and output.

This invention is made in view of the problem mentioned above, and makes it a subject to provide the vehicle information processing system which can provide several information to a driver at an appropriate timing, respectively.

In order to solve the above problems, a vehicle information processing system of the present invention is a vehicle information processing system that processes a plurality of pieces of information provided to a vehicle driver, and each of the plurality of pieces of information is provided to the driver. A provision limit period determining means for determining a provision limit period, which is a period to be provided, a driver factor related to the driver of the vehicle, a driving environment factor related to the environment in which the vehicle travels, and a driving condition of the vehicle Based on at least two factors among the driving state factors to be performed, threshold setting means for setting a provision limit period threshold that is a threshold for the provision limit period, and the vehicle from the plurality of information using the provision limit period threshold Information selection means for selecting information to be provided to the driver.

According to the vehicle information processing system of the present invention, various processes are performed on the input information, and the information is provided to the driver of the vehicle using various methods such as video and audio. More specifically, for example, information on a preceding vehicle or an obstacle is provided as an alarm for preventing a collision, and road information obtained by the car navigation system is provided as guidance information. The "input information" here means information to be provided to the driver or various information for deriving information to be provided. For example, the output values of various sensors in the vehicle and the state of the vehicle And various information provided from outside the vehicle.

The vehicle information processing system according to the present invention includes, for example, one or a plurality of CPU (Central Processing Unit), MPU (Micro Processing Unit), various processors or various controllers, or ROM (Read Only Memory), RAM (Random Access). Memory), various storage units such as buffer memory or flash memory, etc., and various processing units such as a single or a plurality of ECUs (Electronic Controlled Units), various controllers or various computer systems such as microcomputer devices, etc. It can be taken. The vehicle information processing system according to the present invention may be an on-board device fixed to the vehicle, or may be configured as a portable device that is not fixed to the vehicle (for example, a portable navigation system or a tablet terminal). It may be done.

In the operation of the vehicle information processing system according to the present invention, the provision limit period is first determined for each of the plurality of pieces of information by the provision limit period determination means. Here, the “providing limit period” means a period from a reference timing (for example, the current time) to a final timing at which information should be provided (that is, a period during which information provision is effective). It is determined as appropriate according to the type and content of the information provided. For this reason, it can be said that the smaller the value of the provision limit period, the higher the urgency.

More specifically, the provision limit period is determined as a value corresponding to TTC (Time To Contact) in the collision prevention system or a time until reaching the guidance point in the navigation system. Information that is irrelevant to the position (that is, the relative distance to the vehicle) or information that does not change the position (for example, information related to a preceding vehicle having the same speed as that of the host vehicle or a stopped pedestrian at the time of stopping, etc.) Can be treated as infinite. However, regarding information on objects located at a short distance from the vehicle, the provision limit period is suddenly small when a speed difference occurs even if the position does not change at some point and the provision limit period is infinite. Can be a value. For this reason, it is preferable that it can utilize also about the information regarding the distance with the object which information shows in addition to a provision limit period.

When the provision limit period is determined, the threshold setting means sets a provision limit period threshold that is a threshold for the provision limit period. Here, the “providing limit period threshold value” is a threshold value for determining whether or not to provide each information to the driver in the information selection means to be described later, the driver factor related to the driver of the vehicle, the environment in which the vehicle travels Is set based on at least two factors among the driving environment factor related to the driving condition factor and the driving condition factor related to the driving condition of the vehicle. The provision limit period threshold value may be set as a plurality of threshold values corresponding to each of at least two factors of a driver factor, a driving environment factor, and a driving state factor, or may be set as one threshold value collectively. .

When the provision limit period threshold is set, information to be actually provided to the driver is selected from a plurality of information by the information selection means. For example, in the information selection means, information whose provision limit period value is smaller than the provision limit period threshold value is selected as information to be provided to the driver. Information that has not been selected by the information selection means is not provided to the driver at this time, but may be selected by the information selection means and provided to the driver according to a subsequent change in the provision limit period or the provision limit period threshold. .

If information to be provided to the driver is selected using the provision limit period in this way, a unified indicator for a plurality of factors (that is, a driver factor, a driving environment factor, and a driving state factor) from a plurality of information in the vehicle. Can be used to select information to be provided to the driver. Thus, for example, information is provided to the driver at a more appropriate timing than when information is selected based on only one factor. Thereby, for example, it is possible to prevent information having urgency from being immediately provided, or conversely, providing information having no urgency in preference to information having urgency. Furthermore, it is possible to prevent a situation in which information becomes meaningless due to a delay in provision.

In addition, it is considered that there may be a situation where information cannot be appropriately selected only by the above-mentioned provision limit period. In such a case, information may be selected using parameters other than the provision limit period. In other words, the present invention is not limited to the selection of information on the condition of the provision limit period alone, but may select information using other conditions in addition to the provision limit period. .

As described above, according to the vehicle information processing system of the present invention, a plurality of pieces of information can be provided to the driver at appropriate timings.

In one aspect of the vehicle information processing system of the present invention, the vehicle includes an integrated output unit that at least partially integrates and outputs the selected information based on the provision limit period or a predetermined category.

According to this aspect, when a plurality of pieces of information are selected by the selection unit, the plurality of pieces of information are at least partially integrated by the integrated output unit. Here, in particular, the integration of information in the integrated output means is performed based on the provision limit period or a predetermined category. Here, the “predetermined category” is a concept set to distinguish the type of information, and specifically includes categories such as information for preventing collision and information for road guidance, for example. .

When integrating information based on the provision limit period, the integrated output means integrates and outputs, for example, a plurality of pieces of information having close provision limit periods as one piece of information. Further, when integrating information based on the category of information, the integrated output unit integrates and outputs a plurality of pieces of information having the same category as one piece of information, for example.

If the information is integrated and output as described above, a plurality of pieces of information can be provided to the driver at the same time, so that it is possible to provide information more suitably.

In another aspect of the vehicle information processing system of the present invention, the threshold value setting means sets the provision limit period threshold value using at least one of the driver's arousal level, line-of-sight direction, and driving experience as the driver factor. .

According to this aspect, since at least one of the driver's arousal level, line-of-sight direction, and driving experience is used as a driver factor, it is possible to set a more appropriate provision limit period threshold value. Therefore, information can be provided to the driver at a more appropriate timing.

For example, if the driver's awakening level is low, the driver's line-of-sight direction is not the front, or if the driver has little driving experience, it is effective to provide information for preventing a collision at an early timing. Collisions can be prevented.

In another aspect of the vehicle information processing system of the present invention, the threshold setting means uses the at least one of the travel location, travel time, and presence / absence of a preceding vehicle as the travel environment factor as the provision limit period threshold value. Set.

According to this aspect, since at least one of the travel location of the vehicle, the travel time, and the presence or absence of the preceding vehicle is used as a travel environment factor, it is possible to set a more appropriate provision limit period threshold value. Therefore, information can be provided to the driver at a more appropriate timing.

For example, when the travel location of the vehicle is an expressway, it is considered that there is no target at a position very close to the vehicle, and thus it is only necessary to make it difficult to select information on a target at a short distance. On the other hand, when the vehicle is traveling on a general road (especially a residential area or a road near a school), there is a high possibility that a relatively short distance object such as a pedestrian exists. What is necessary is just to make it easy to select information.

Further, for example, when the traveling time is a school attendance time or a school leaving time, information for a pedestrian may be easily selected. In addition, when the traveling time is evening or night, it is considered that it is easy to overlook even a target at a close position compared to bright daytime, and thus information on a target at a short distance may be easily selected.

Also, for example, when there is a preceding vehicle, there is a risk of a collision with the preceding vehicle, so it is only necessary to make it easy to select information for the preceding vehicle.

In another aspect of the vehicle information processing system of the present invention, the threshold value setting means sets the provision limit period threshold value using at least one of the vehicle speed and on / off of the driving support function as the driving state factor. .

According to this aspect, since at least one of the vehicle speed and the on / off of the driving support function is used as a driving state factor, a more appropriate provision limit period threshold value can be set. Therefore, information can be provided to the driver at a more appropriate timing.

Here, the “driving support function” is control that is automatically performed on the vehicle side in order to assist driving by the driver. For example, ACC (Adaptive Cruise Control), LKA (Lane Keeping Assist), PCS (Pre -Crash Safety).

For example, when the vehicle speed is relatively fast, if the information for preventing the collision is provided at an early timing, the collision can be effectively prevented.

Also, for example, when the driving support function is turned on, information corresponding to the driving support function may be easily selected.

The operation and other advantages of the present invention will be clarified from embodiments for carrying out the invention described below.

The operation signal input unit 130 inputs various operation signals and setting signals in the vehicle to the information processing unit 200. Examples of signals handled by the operation signal input unit 130 include operation signals such as energy flow, air conditioner, parking brake, VSC (Vehicle Stability 、 Control), door, ACC, LKA, and headlamp leveling, or signals indicating setting states.

The vehicle sensor signal input unit 140 inputs various parameters detected at each part of the vehicle to the information processing unit 200. Examples of signals handled by the vehicle sensor signal input unit include signals indicating vehicle speed, engine speed, engine coolant temperature, fuel remaining amount, shift position, and the like.

The driving support sensor signal input unit 150 inputs a signal used in the driving support system that supports the driving operation of the driver to the information processing unit 200. The driving assistance sensor signal input unit 150 includes, for example, a millimeter wave radar, a front camera, a driver camera that displays a driver, a 700 MHz communication device, and the like.

The information processing unit 200 constitutes a main part of the vehicle information processing system according to the present embodiment, for example, as an ECU or the like. The information processing unit 200 includes a TTI (Time To Information) calculating unit 210, a driving state factor processing unit 220, a driving environment factor processing unit 230, a driver factor processing unit 240, and a semantic integration processing unit 250.

The TTI calculation unit 210 is an example of the “providing limit period determination unit” of the present invention, and includes the above-described visual assistance sensor signal input unit 110, multimedia information input unit, operation signal input unit 130, vehicle sensor signal input unit 140, and A TTI is calculated for information input from the driving support sensor input unit 150. The TTI here is an example of the “provision limit period” in the present invention, and means the time until the information is required. The value of TTI can be calculated based on, for example, preset conditions.

The traveling state factor processing unit 220 selects information to be output based on a traveling state factor that is a factor relating to the traveling state of the vehicle from among a plurality of pieces of information for which the TTI has been calculated. As a driving | running | working state factor, the speed of a vehicle, on / off of a driving assistance function, etc. are mentioned, for example.

The driving environment factor processing unit 230 selects information to be output based on a driving environment factor that is a factor relating to the driving environment of the vehicle, from among a plurality of pieces of information for which the TTI is calculated. Examples of the travel environment factor include the travel location of the vehicle, the travel time, the presence / absence of a preceding vehicle, and the like.

The driver factor processing unit 240 selects information to be output from a plurality of pieces of information for which the TTI has been calculated, based on driving environment factors that are factors relating to the driver of the vehicle. The driving environment factors include, for example, a car driver's arousal level, line-of-sight direction, and driving experience.

The traveling state factor processing unit 220, the traveling environment factor processing unit 230, and the driver factor processing unit 240 described above are examples of the “threshold setting unit” and the “information selection unit” of the present invention. Details of specific processing in each part will be described later.

The meaning integration processing unit 250 is an example of the “integrated output unit” of the present invention, and is selected by the driving state factor processing unit 220, the driving environment factor processing unit 230, and the driver factor processing unit 240 (that is, output with priority). A plurality of pieces of information determined to be integrated are integrated based on TTI, category, and the like.

The output switching unit 300 is configured to be able to switch whether or not to output the information selected to be provided to the driver by the information processing unit 200 to the information output unit 400. For example, the output switching unit 300 determines whether or not to output information based on a user operation or setting, and outputs the information to the information output unit 400.

The information output unit 400 is configured to be able to provide the information output from the output switching unit 300 to the driver by various methods. The information output unit 400 includes, for example, a center display, a rear seat display, a speaker and meter display mounted on a vehicle, or a portable mobile device.

Next, the operation of the vehicle information processing system according to the present embodiment will be described with reference to FIGS. FIG. 2 is a flowchart showing the operation of the vehicle information processing system according to this embodiment. FIG. 3 is a conceptual diagram illustrating the processing method of each information in the vehicle information processing system according to the present embodiment in order.

In FIG. 2, when information is input from the visual assistance sensor signal input unit 110, the multimedia information input unit, the operation signal input unit 130, the vehicle sensor signal input unit 140, and the driving support sensor input unit 150 to the information processing unit 200. First, the TTI calculation unit 210 calculates the TTI of each information (step S101).

As shown in FIG. 3, when the TTI is calculated, each piece of information is rearranged according to the magnitude of the TTI value. In the following description, it is assumed that information A, information B, information C, information D,..., Information ZZZ as shown in FIG.

Returning to FIG. 2, when the TTI calculation unit 210 calculates the TTI, the driving state factor processing unit 220 selects information based on the driving state factor (step S102). The driving state factor processing unit 220 selects information to be provided to the driver using a threshold set based on the driving state factor.

As shown in FIG. 3, if a threshold value P is set based on a driving state factor, information A, information B, and information C having a TTI smaller than the threshold value P are selected as information to be provided to the driver with priority. On the other hand, information DZZ having information TZZ having a TTI larger than the threshold value P is not prioritized.

Returning to FIG. 2, when the processing in the driving state factor processing unit 220 is completed, the driving environment factor processing unit 230 subsequently selects information based on the driving environment factor (step S103). Similar to the driving state factor processing unit 220, the driving environment factor processing unit 230 selects information to be provided to the driver using a threshold set based on the driving environment factor.

In FIG. 3, it is assumed that only information C among information A, information B, and information C is information regarding pedestrians. Here, for example, when the vehicle is traveling on an expressway and the driving environment factor processing unit sets a threshold value that does not give priority to the information on the pedestrian, the information C Is a non-priority setting. That is, only information A and information B are selected.

Referring back to FIG. 2, when the processing in the driving environment factor processing unit 230 ends, the driver factor processing unit 240 selects information based on the driver factor (step S104). Similar to the driving state factor processing unit 220 and the driving environment factor processing unit 230, the driver factor processing unit 240 selects information to be provided to the driver using a threshold set based on the driver factor.

As shown in FIG. 3, if a threshold value Q greater than the threshold value P is set based on the driving state factor, the upper limit of the threshold value is increased, so that the information D that has been set to be non-priority until then should be output with priority. Selected as information. On the other hand, the information C that is non-prioritized because it is pedestrian information is left in the non-priority setting although the TTI is smaller than the threshold value Q.

Returning to FIG. 2, when the processing in each of the driving state factor processing unit 220, the driving environment factor processing unit 230, and the driver factor processing unit 240 is completed, the semantic integration processing unit 250 selects the selected information (ie, information A, information B and information D) are integrated based on TTI and category (step S105).

Here, for example, the information A is the preceding vehicle information that “the preceding vehicle has started decelerating”, the information B is the following vehicle information that “the following vehicle is approaching”, and the information D is “traveling the overtaking lane” Assume that the adjacent lane vehicle information indicates that the vehicle inside is staggering. In this case, the information A and the information B, which are close to each other, are integrated into the information “Please pay attention to the distance between the front and rear vehicles”.

When the process in the meaning integration processing unit 250 is completed, the information is output to the output switching unit 300, and it is determined whether or not the information can be provided (step S106). If it is determined that the information cannot be output (step S106: NO), the series of processing ends without outputting the information. On the other hand, when it is determined that the information can be output (step S106: YES), the information is output to the information output unit 400 and provided to the driver (step S107).

Specifically, in the case of the above-described example, the information “Please pay attention to the distance to the front and rear vehicles” corresponding to the information A and B is first provided to the driver using video, audio, etc., and then the information D The information “Please pay attention to the vehicle in the right lane” corresponding to is provided to the driver using video or audio.

Next, the process by the vehicle information processing system according to the present embodiment will be described more specifically with reference to FIGS.

First, information priority setting in a situation where the driving state factors are different will be described with reference to FIGS. Here, FIGS. 4 and 5 are conceptual diagrams showing priority setting of information according to different situations with different driving state factors.

As shown in FIG. 4, it is assumed that information indicated by X1 to X11 in the drawing is input to the vehicle information processing system according to the present embodiment. The position of the point indicating information indicates the positional relationship between the vehicle 500 and the object of information, and the arrow extending from the point indicating information indicates the moving direction and the moving speed of the information object. Yes.

For example, the information X1 is information indicating an object that moves at a relatively high speed in the right direction when viewed from the vehicle 500 at a considerably far position (outside the long-distance zone) on the left front side of the vehicle 500. Further, the information X5 is information indicating a target that is stopped at a relatively far position (in the long distance zone) in front of the front of the vehicle 500. The information X8 is information indicating an object that moves at a relatively low speed in the right direction when viewed from the vehicle at a relatively close position (in the short distance zone) on the right rear side of the vehicle 500. The information X9, the information X10, and the information X11 are information that does not depend on the distance from the vehicle 500, and the TTI is set as infinity.

Here, for example, when the vehicle 500 is stopped or the driving support function is turned on, the driving state factor processing unit 220 determines that all information should be preferentially provided to the driver. . That is, the threshold value based on the driving state factor is set as a value including up to infinity, and all of the information X1 to information X11 is output from the driving state factor processing unit 220 in a state where priority is set.

In FIG. 5, for example, when the vehicle is traveling, the traveling state factor processing unit 220 prioritizes information X3 and information X8, which are information in a short-distance zone existing at a relatively close distance to the vehicle 500. At the same time, information X1, X2, X4, and X5, which are information whose TTI is equal to or less than the threshold value p (that is, information related to an object approaching the vehicle 500), are preferentially set. On the other hand, information X6, X7, X9, X10, and X11, which are other information, are set to be non-prioritized.

As described above, more appropriate information can be provided to the driver by changing the information selected according to the driving state factor. Therefore, for example, a collision of the vehicle 500 can be effectively prevented.

Next, the priority setting of information in a situation where driving environment factors are different will be described with reference to FIGS. Here, FIGS. 6 and 7 are conceptual diagrams showing priority setting of information according to different situations of driving environment factors.

In FIG. 6, for example, it is assumed that a vehicle 500 is traveling on an expressway (excluding a service area and a parking area), and a preceding vehicle exists. In this case, in the driving environment factor processing unit 230, the information X3 and X8, which are information existing in the short-distance zone, is set as non-priority as a false detection (however, the clearance sonar signal is an exception). Information X5 and X7, which are information on pedestrians that cannot exist on the highway, are also set as non-priority as false detections. Further, the information X9, X10, and X11 having an infinite TTI is also set to be non-priority because the urgency is low. As a result, information X1, X2, X4, and X6 are output from the driving environment factor processing unit 230 as information that should be prioritized.

In FIG. 7, for example, it is assumed that the vehicle 500 is traveling on a general road near the school in the evening, which is school leaving time. In this case, the driving environment factor processing unit 230 prioritizes information X3, X5, and X7, which are pedestrian information. On the other hand, X1, X2, X4, X6, X7, X8, X9, X10, and X11, which are information other than pedestrians, are set as non-priority settings.

As described above, more appropriate information can be provided to the driver by changing the information selected according to the driving environment factors. Therefore, for example, a collision of the vehicle 500 can be effectively prevented.

Next, priority setting of information based on driver factors will be described with reference to FIG. FIG. 8 is a conceptual diagram showing priority setting of information based on driver factors.

In FIG. 8, it is assumed that the vehicle 500 is traveling on a highway and a preceding vehicle is present, as in the case of the traveling environment of FIG. In this case, the driver factor processing unit 240 performs priority setting using a threshold value q based on the driver's arousal level, a threshold value r based on the driver's line-of-sight direction, and a threshold value s based on the driving experience of the driver. Thereby, the information X5, which is set to be non-priority in FIG. 6, is set with priority because the TTI is smaller than the threshold value q or the threshold value s.

Note that the threshold value q based on the driver's arousal level increases as the driver's awakening level decreases (that is, the lower the arousal level, the higher the TTI information is also prioritized). In addition, the threshold value r based on the driver's line-of-sight direction is set so that information regarding an object located in the line-of-sight direction is not easily set. Further, the threshold value s based on the driving experience of the driver increases as the driving experience of the driver decreases (that is, as the driving experience decreases, information having a larger TTI is also prioritized).

As described above, if the information selected in accordance with the driver factor is changed, more appropriate information can be provided to the driver. Therefore, for example, a collision of the vehicle 500 can be effectively prevented.

As described above, according to the vehicle information processing system according to the present embodiment, since information to be provided to the driver is selected using TTI, a plurality of factors (i.e., a plurality of factors (i.e., Information to be provided to the driver can be selected using a unified index for driver factors, driving environment factors, and driving condition factors. Thus, for example, information is provided to the driver at a more appropriate timing than when information is selected based on only one factor. Thereby, for example, it is possible to prevent information having urgency from being immediately provided, or conversely, providing information having no urgency in preference to information having urgency. Furthermore, it is possible to prevent a situation in which information becomes meaningless due to a delay in provision.

The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification. Processing systems are also within the scope of the present invention.
