Description

The present invention relates to an abnormality determination device and an abnormality determination system that determine whether there is an abnormality in a vehicle.

Generally, the presence or absence of an abnormality in a vehicle is determined based on a change in the detection result of an on-vehicle sensor mounted on the vehicle. Furthermore, for example, Patent Document 1 describes determining an abnormality in another vehicle-mounted device based on a detection result of a steering sensor.

Japanese Patent Application Publication No. 2007-276559

For example, when determining an abnormality based on the detection result of an on-board sensor, it is necessary to determine whether the change in the detection result of the on-board sensor is caused by the vehicle abnormality or the external environment such as the shape of the road surface. may be difficult. Therefore, in this technical field, there is a need to accurately determine abnormalities in a vehicle while suppressing the influence of the external environment.

One aspect of the present invention is an abnormality determination device that determines the presence or absence of an abnormality in a vehicle, and includes correspondence information in which vehicle information acquired by the vehicle is associated with position information indicating a position where the vehicle information is acquired. The information acquisition unit that acquires the vehicle information is compared with the vehicle information of the correspondence information acquired at the same position among the plurality of correspondence information acquired by the information acquisition unit, and it is determined whether the vehicle information shows the same tendency. A tendency determination unit to determine, and an abnormality in which if the trend determination unit determines that there is correspondence information that includes vehicle information with a different tendency from other vehicle information, there is an abnormality in the vehicle from which the correspondence information is acquired. A determination unit is provided.

In this abnormality determination device, the tendency determination unit compares vehicle information pieces of corresponding information acquired at the same location, and determines whether the vehicle information shows the same tendency. For example, when vehicle information changes due to the external environment, vehicle information included in other corresponding information acquired at the same location also changes. Further, when a vehicle abnormality occurs and the vehicle information changes due to the vehicle abnormality, the tendency of the change is different from that of the vehicle information included in other corresponding information acquired at the same location. In other words, the trend determination unit can determine whether or not the vehicle information has changed due to a vehicle abnormality by using the tendency of changes in vehicle information of corresponding information acquired at the same location. can. If it is determined that the vehicle information has a tendency different from others, the abnormality determination unit determines that there is an abnormality in the vehicle from which the corresponding information including this vehicle information is obtained. In this way, the abnormality determination device can accurately determine the abnormality of the vehicle while suppressing the influence of the external environment.

Another aspect of the present invention is an abnormality determination system that determines the presence or absence of an abnormality in a vehicle, which includes a plurality of vehicle-mounted determination devices each mounted on a plurality of vehicles, and a vehicle-mounted determination device based on the determination results of the vehicle-mounted determination devices. a determination processing device that determines an abnormality, and the in-vehicle determination device associates vehicle information acquired by a vehicle in which the in-vehicle determination device is installed with position information indicating a position where the vehicle information was acquired. A first information acquisition unit that acquires the correspondence information obtained by the first information acquisition unit compares the vehicle information of the correspondence information acquired at the same position among the plurality of correspondence information acquired by the first information acquisition unit, and determines that the vehicle information tends to be the same. If the first tendency determination unit determines that there is corresponding information that includes vehicle information with a different tendency from other vehicle information, the first tendency determination unit determines whether the vehicle information has a different tendency from other vehicle information. a transmission unit that transmits response information including the error response information to the determination processing device as the abnormality response information, and the determination processing device includes a second information acquisition unit that acquires the abnormality response information transmitted from the transmission unit; Based on the abnormality response information acquired by the acquisition unit and the response information acquired from an in-vehicle determination device other than the in-vehicle determination device that transmitted the abnormality response information, the vehicle information of the abnormality response information is the same as the abnormality response information. A second tendency determination unit compares the vehicle information of the response information acquired at the location and determines whether the vehicle information shows the same tendency; and the second tendency determination unit compares the vehicle information of the abnormality response information. and an abnormality determination unit that determines that there is an abnormality in a vehicle equipped with an in-vehicle determination device that is a transmission source of the abnormality handling information when it is determined that the tendency of the handling information is different from the vehicle information.

In this abnormality determination system, first, the first trend determination unit of the on-vehicle determination device compares vehicle information pieces of corresponding information acquired at the same location, and determines whether or not the vehicle information shows the same tendency. be done. For example, when vehicle information changes due to the external environment, vehicle information included in other corresponding information acquired at the same location also changes. Further, when a vehicle abnormality occurs and the vehicle information changes due to the vehicle abnormality, the tendency of the change is different from that of the vehicle information included in other corresponding information acquired at the same location. In other words, the first tendency determination unit determines whether or not the vehicle information has changed due to a vehicle abnormality by using the tendency of change between the vehicle information of the corresponding information acquired at the same location. be able to. Next, in the determination and treatment device, the second tendency determination section compares the abnormality response information transmitted from the on-vehicle determination device with the response information transmitted from another vehicle, similarly to the first trend determination section. If it is determined that the vehicle information of the abnormality handling information has a tendency different from others, the abnormality determination unit determines that there is an abnormality in the vehicle that is the source of the abnormality handling information.

In this manner, in the abnormality determination system, first, the on-vehicle determination device compares correspondence information acquired at the same location. If the in-vehicle determination device determines that the vehicle information trends are different, the determination processing device compares the abnormality response information with the response information acquired from other vehicles and determines whether there is an abnormality in the vehicle. be done.

As described above, the abnormality determination system can accurately determine vehicle abnormalities while suppressing the influence of the external environment by comparing abnormality response information acquired at the same location with other response information. can. Further, when the in-vehicle determination device determines that the tendency is different from others, the abnormality response information is transmitted to the determination processing device and compared with other response information. Therefore, the abnormality determination system can suppress an increase in the amount of communication between the in-vehicle determination device and the determination processing device.

In the abnormality determination device described above, the vehicle information may include at least one of a detected value of an on-vehicle sensor and an instruction value of a driving operation of the vehicle. In this case, the abnormality determination device can determine, as the abnormality of the vehicle, an abnormality in at least one of the on-vehicle sensor and the instruction value of the driving operation of the vehicle.

According to various aspects of the present invention, it is possible to accurately determine an abnormality in a vehicle while suppressing the influence of the external environment.

Embodiments of the present invention will be described below with reference to the drawings. In each figure, the same or corresponding elements are given the same reference numerals, and redundant explanations will be omitted.

(First embodiment)
First, an abnormality determination system according to a first embodiment will be described. As shown in FIG. 1, an abnormality determination system 1 is a system that determines whether or not a vehicle V has an abnormality. For example, the abnormality determination system 1 may determine abnormality in vehicles V traveling on the same route within a limited area (areas where work vehicles travel in airports, warehouses, etc., bus routes, etc.). However, the abnormality determination system 1 is not limited to determining abnormalities of vehicles V traveling within these limited areas, but may also determine abnormalities of vehicles V traveling within unlimited areas. can.

The abnormality determination system 1 includes a plurality of on-vehicle determination devices 10 each mounted on a plurality of vehicles V, and a determination processing device 20 installed in a server or the like outside the vehicle V. The determination processing device 20 performs wireless communication with the on-vehicle determination device 10 and determines whether the target vehicle V is abnormal.

First, details of the in-vehicle determination device 10 will be explained. As shown in FIG. 2, the in-vehicle determination device 10 includes a communication section 11 and an in-vehicle determination (electronic control unit) ECU 12. The communication unit 11 is a communication device that performs wireless communication with the determination processing device 20 (communication unit 21). The method of wireless communication in the communication unit 11 is not particularly limited.

Physically, the vehicle-mounted determination ECU 12 is an electronic control unit that includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. In the vehicle-mounted determination ECU 12, various functions are realized by, for example, executing programs recorded in a ROM or RAM with a CPU.

The on-vehicle determination ECU 12 functionally includes a first information acquisition section 13, a first tendency determination section 14, and a transmission section 15. The first information acquisition unit 13 provides correspondence information in which vehicle information acquired by the vehicle V (own vehicle) in which the in-vehicle determination device 10 is mounted is associated with position information indicating the position where the vehicle information is acquired. get.

Note that the vehicle information includes at least one of detection values of various on-vehicle sensors mounted on the vehicle V and instruction values for driving operations of the vehicle V. As an example, the detected value of the on-vehicle sensor may include either longitudinal acceleration or lateral acceleration detected by the acceleration sensor. As an example, the instruction value for the driving operation of the vehicle V may include, for example, an instruction value for the operating angle when the vehicle V is an automatic driving vehicle. The detected values of the on-vehicle sensors and the instruction values for driving operations are not limited to those listed as examples.

Furthermore, the position information may be, for example, position information acquired by a GPS receiver mounted on the vehicle V. As the location information, various known location information can be used. The first information acquisition unit 13 may acquire vehicle information and position information, associate them, and acquire the associated vehicle information and position information as correspondence information.

The first tendency determination unit 14 compares vehicle information of correspondence information acquired at the same position among the plurality of correspondence information acquired by the first information acquisition unit 13. That is, the first tendency determination unit 14 compares vehicle information pieces of correspondence information acquired at different timings at a predetermined position. Then, the first trend determination unit 14 determines whether or not these pieces of vehicle information indicate the same trend. Note that showing the same tendency includes not only vehicle information being completely the same, but also cases in which the vehicle information changes in a similar manner.

An example of the determination process performed in the first trend determination unit 14 will be described using FIGS. 3(a) to 3(c). As an example, FIGS. 3A to 3C show temporal changes in the detected value of the longitudinal acceleration when the vehicle V passes the point P. FIG. 3(a) shows newly detected detection values, and FIG. 3(b) and FIG. 3(c) show previously detected detection values.

When the vehicle V passes the point P, the first trend determination unit 14 generates correspondence information in which the temporal change in longitudinal acceleration shown in FIG. 3(a) is associated with the position information of the point P as vehicle information. , is acquired from the first information acquisition unit 13. Then, the first trend determination unit 14 extracts the correspondence information at the point P from among the correspondence information acquired in the past. Note that the first trend determination unit 14 sequentially stores the correspondence information acquired from the first information acquisition unit 13.

Here, for example, the first trend determination unit 14 uses correspondence information in which the temporal change in longitudinal acceleration shown in FIG. 3(b) is associated with the position information of the point P as vehicle information, and Correspondence information in which the temporal change in longitudinal acceleration shown in (c) is associated with the position information of point P is extracted. Then, the first trend determination unit 14 compares the vehicle information (the longitudinal acceleration shown in FIGS. 3(a) to 3(c)) of these pieces of corresponding information. Here, the tendency of the temporal change in longitudinal acceleration shown in FIG. 3(a) is different from the temporal change in longitudinal acceleration shown in FIGS. 3(b) and 3(c) acquired in the past. Therefore, the first tendency determination unit 14 determines that the vehicle information of the correspondence information newly acquired from the first information acquisition unit 13 has a different tendency from other correspondence information at the point P.

Note that, as shown in FIGS. 3(a) to 3(c), when the detected value of the longitudinal acceleration differs at point P, for example, there was no dent in the road surface at point P until now; It is conceivable that when the vehicle traveled through point P this time, there were potholes on the road surface. Another possibility is that there was no abnormality in the acceleration sensor mounted on vehicle V until now, but now an abnormality has occurred in the acceleration sensor, and the detected value of longitudinal acceleration has a different tendency than before. It is possible that this happens. In this way, cases where vehicle information trends differ at the same point can be considered to be due to the external environment or due to vehicle abnormality.

When the first tendency determination unit 14 determines that there is correspondence information that includes vehicle information with a different tendency from other vehicle information, the transmission unit 15 determines the correspondence information that includes vehicle information with a different tendency as abnormality response information. It is transmitted to the processing device 20. Here, the transmitting unit 15 transmits the abnormality response information to the determination processing device 20 via the communication unit 11 by wireless communication.

Next, details of the determination processing device 20 will be explained. The determination processing device 20 determines whether the vehicle V is abnormal based on the determination result of the on-vehicle determination device 10. More specifically, as shown in FIG. 1, the determination processing device 20 includes a communication section 21 and an abnormality determination ECU 22. The communication unit 21 is a communication device that performs wireless communication with the in-vehicle determination device 10 (communication unit 11).

The abnormality determination ECU 22 is an electronic control unit that physically has the same configuration as the vehicle-mounted determination ECU 12. The abnormality determination ECU 22 functionally includes a second information acquisition section 23, a second tendency determination section 24, and an abnormality determination section 25.

The second information acquisition unit 23 acquires the abnormality handling information transmitted from the communication unit 11 of the on-vehicle determination device 10. Here, the second information acquisition unit 23 acquires the abnormality handling information transmitted from the communication unit 11 of the on-vehicle determination device 10 via the communication unit 21.

The second trend determination unit 24 uses the abnormality response information acquired by the second information acquisition unit 23 and the response information acquired from the in-vehicle determination device 10 other than the in-vehicle determination device 10 that transmitted the abnormality response information, The vehicle information of the abnormality handling information is compared with the vehicle information of the handling information acquired at the same location as the abnormality handling information. Then, the second trend determining unit 24 determines whether the vehicle information in the abnormality handling information and the vehicle information in the handling information show the same tendency. Here, the second trend determining section 24 can use the same method as the first trend determining section 14 to determine whether or not the same tendency is shown.

Note that the number of in-vehicle determination devices 10 other than the in-vehicle determination device 10 that transmitted the abnormality response information may be one or more than one. That is, the on-vehicle determination device 10 may be an on-vehicle determination device 10 that is mounted on one or more vehicles V other than the vehicle V in which the on-vehicle determination device 10 that transmitted the abnormality response information is mounted. In addition, the second trend determination unit 24 acquires response information at each point from each on-vehicle determination device 10 mounted on a plurality of vehicles V at a predetermined timing in order to perform a comparison process with the abnormality response information. I remember. This predetermined timing can be set as appropriate. Further, the response information acquired at this predetermined timing may be response information acquired at a timing earlier than the time when the abnormality response information is acquired, or even earlier than the time when the abnormality response information is acquired. It may be correspondence information acquired at a later timing. That is, the second trend determination unit 24 may compare trends using correspondence information acquired in the past from the time when the abnormality correspondence information was acquired. Further, the second trend determination unit 24 may compare trends using response information acquired later (in the future) than the time point when the abnormality response information is acquired. When performing the comparison process, the second tendency determination unit 24 determines whether correspondence information, among the plurality of correspondence information, is transmitted from an in-vehicle determination device 10 different from the in-vehicle determination device 10 that transmitted the abnormality response information, and which is an abnormality. Correspondence information acquired at the same location as the correspondence information is extracted and used.

Here, the determination processing performed by the second tendency determination section 24 will be explained using the drawings. First, a case will be described where the tendency of the vehicle information in the abnormality response information is different from others. FIGS. 4(a) to 4(e) show vehicle information (here, temporal changes in the detected value of longitudinal acceleration) when the vehicle V passes the point P. Further, the vehicle V that is the source of the abnormality response information acquired by the second information acquisition unit 23 is assumed to be the first vehicle V. FIG. 4A shows vehicle information of abnormality response information for the first vehicle V acquired by the second information acquisition unit 23. Further, FIGS. 4(b) and 4(c) show vehicle information of abnormality response information for a second vehicle and a third vehicle V other than the first vehicle V, respectively.

In this case, the second tendency determination unit 24 uses the vehicle information of the abnormality response information as shown in FIG. 4(a) and the second vehicle information as shown in FIG. 4(b) and FIG. 4(c). The vehicle information of the correspondence information for V and the third vehicle V is compared. The vehicle information of the abnormality response information shown in FIG. 4(a) has a different tendency from the vehicle information of the response information shown in FIGS. 4(b) and 4(c). Therefore, the second tendency determination unit 24 determines that the vehicle information of the abnormality response information of the first vehicle V has a different tendency from the vehicle information of the response information of the second vehicle V and the third vehicle V.

Next, a case will be described in which the tendency of the vehicle information in the abnormality response information is the same as other vehicle information. FIG. 4(d) shows the vehicle information of the abnormality response information for the first vehicle V acquired by the second information acquisition unit 23. Further, FIGS. 4(e) and 4(f) show vehicle information of abnormality response information for a second vehicle and a third vehicle V other than the first vehicle V, respectively.

In this case, the second trend determination unit 24, as described above, uses the vehicle information of the abnormality response information as shown in FIG. 4(d) and the vehicle information as shown in FIG. 4(e) and FIG. 4(f), for example. The vehicle information of the corresponding information for the second vehicle V and the third vehicle V is compared. The vehicle information of the abnormality response information shown in FIG. 4(d) has the same tendency as the vehicle information of the response information shown in FIGS. 4(e) and 4(f). Therefore, the second tendency determination unit 24 determines that the vehicle information of the abnormality response information of the first vehicle V has the same tendency as the vehicle information of the response information of the second vehicle V and the third vehicle V.

If the second trend determining unit 24 determines that the vehicle information of the abnormal response information has a tendency different from the vehicle information of the response information used for comparison, the abnormality determination unit 25 determines the transmission source of the abnormality response information. It is determined that there is an abnormality in the vehicle V on which the in-vehicle determination device 10 is mounted.

For example, a case where the vehicle information of the abnormality response information has a different tendency from the vehicle information of the response information of another vehicle means that the abnormality is not caused by the external environment but is considered to be in the vehicle V that transmitted the abnormality response information. I can do it. On the other hand, when the vehicle information of the abnormality response information has the same tendency as the vehicle information of the response information of another vehicle, it can be considered that the same vehicle information was acquired due to the external environment. Therefore, the abnormality determining section 25 can determine whether or not there is an abnormality in the vehicle V based on the determination result of the second tendency determining section 24. For example, in the example described using FIGS. 4(a) to 4(c), it is determined that the first vehicle V that transmitted the abnormality response information has an abnormality.

As described above, in the abnormality determination system 1, first, the first trend determination unit 14 of the on-vehicle determination device 10 compares the vehicle information of the corresponding information acquired at the same position in the vehicle-mounted determination device 10, It is determined whether the vehicle information shows the same tendency. For example, when vehicle information changes due to the external environment, vehicle information included in other corresponding information acquired at the same location also changes. Further, when a vehicle abnormality occurs and the vehicle information changes due to the vehicle abnormality, the tendency of the change is different from that of the vehicle information included in other corresponding information acquired at the same location. In other words, the first trend determination unit 14 determines whether the vehicle information has changed due to a vehicle abnormality by using the tendency of change between vehicle information pieces of temporally different correspondence information acquired at the same location. It can be determined whether or not. In this manner, in the on-vehicle determination device 10 of each vehicle V, a determination is made as to whether or not the vehicle information has changed due to vehicle abnormality.

Next, in the determination processing device 20, the second tendency determination unit 24, like the first tendency determination unit 14, compares the abnormality response information transmitted from the on-vehicle determination device 10 with the correspondence information transmitted from other vehicles V. Make a comparison. If it is determined that the abnormality handling information has a tendency different from others, the abnormality determination unit 25 determines that there is an abnormality in the vehicle V that is the source of the abnormality handling information.

In this way, in the abnormality determination system 1, first, the on-vehicle determination device 10 compares correspondence information acquired at the same position. If the on-vehicle determination device 10 determines that the tendencies of the vehicle information are different, the determination processing device 20 compares the abnormality response information with the correspondence information acquired from other vehicles V, and determines the abnormality of the vehicle V. The presence or absence is determined.

As described above, the abnormality determination system 1 can accurately determine vehicle abnormalities while suppressing the influence of the external environment by comparing abnormality response information acquired at the same location with other response information. I can do it.

Further, in the abnormality determination system 1, when the in-vehicle determination device 10 determines that the tendency is different from that of others, the abnormality response information is transmitted to the determination processing device 20 and compared with other response information. Therefore, the abnormality determination system 1 can suppress an increase in the amount of communication between the in-vehicle determination device 10 and the determination processing device 20.

The vehicle information includes at least one of a detected value of an on-vehicle sensor and an instruction value of a driving operation of the vehicle. In this case, the abnormality determination system 1 can determine, as the abnormality of the vehicle V, an abnormality in at least one of the on-vehicle sensor and the instruction value of the driving operation of the vehicle.

(Second embodiment)
Next, an abnormality determination device according to a second embodiment will be described. As shown in FIG. 5, the abnormality determination device 1A in this embodiment is a device installed in a server or the like outside the vehicle. The abnormality determination device 1A acquires correspondence information from a plurality of vehicles V, and determines whether or not each vehicle V has an abnormality. As with the abnormality determination system 1 according to the first embodiment, the abnormality determination device 1A may determine abnormality of the vehicle V within a limited area, for example. However, the abnormality determination device 1A is not limited to determining abnormalities of vehicles V traveling within these limited areas, but may also determine abnormalities of vehicles V traveling within unlimited areas. can.

The abnormality determination system 1 includes a communication section 31 and an abnormality determination ECU 32. The communication unit 31 is a communication device that performs wireless communication with the vehicle V. The method of wireless communication in the communication unit 31 is not particularly limited.

The abnormality determination ECU 32 is an electronic control unit that physically has the same configuration as the vehicle-mounted determination ECU 12 in the first embodiment. The abnormality determination ECU 32 functionally includes an information acquisition section 33, a trend determination section 34, and an abnormality determination section 35.

The information acquisition unit 33 performs wireless communication with the vehicle V via the communication unit 31 and acquires correspondence information from each of the plurality of vehicles V. Similar to the first embodiment, this correspondence information is information in which vehicle information acquired by each vehicle V is associated with position information indicating the position where the vehicle information is acquired. In this way, each vehicle V has a function of generating correspondence information and transmitting the generated correspondence information to the abnormality determination device 1A.

The tendency determination unit 34 compares vehicle information of correspondence information acquired at the same position among the plurality of correspondence information acquired by the information acquisition unit 33. Then, the trend determining unit 34 determines whether the vehicle information shows the same trend. The determination of whether the same tendency is shown by the trend determination unit 34 here can be performed using the same method as the first trend determination unit 14 in the first embodiment. Note that the trend determination unit 34 acquires and stores correspondence information at each point from each of the plurality of vehicles V at a predetermined timing in order to perform a comparison process of correspondence information. This predetermined timing can be set as appropriate.

For example, a case will be described in which the tendency determination unit 34 compares the tendency of the correspondence information of the first vehicle V at the point P with other correspondence information. In this case, the trend determination unit 34 compares, for example, the correspondence information of the second vehicle V and the third vehicle V at the point P with the correspondence information of the first vehicle V. Note that the correspondence information to be compared with the correspondence information of the first vehicle V is not limited to using the correspondence information of two vehicles V other than the first vehicle V, and is not limited to using the correspondence information of two vehicles V other than the first vehicle V. The correspondence information of the vehicle V may be used. Further, the correspondence information to be compared with the correspondence information of the first vehicle V may include correspondence information of the first vehicle V acquired at a timing different from this correspondence information.

Further, the correspondence information to be compared with the correspondence information of the first vehicle V is correspondence information acquired at a timing earlier than the time when the correspondence information of the first vehicle V, which is the source of comparison, is acquired. Alternatively, the correspondence information may be acquired at a later timing than the time when the correspondence information of the first vehicle V that is the basis of comparison is acquired. In other words, the trend determination unit 34 may perform the trend comparison using correspondence information acquired in the past from the point in time when the correspondence information of the first vehicle V, which is the source of the comparison, was acquired. Further, the trend determination unit 34 may perform the trend comparison using correspondence information acquired after (in the future) the time when the correspondence information of the first vehicle V, which is the basis of the comparison, is acquired.

If the trend determining unit 34 determines that there is corresponding information that includes vehicle information with a different tendency from other vehicle information, the abnormality determining unit 35 determines that there is an abnormality in the vehicle V from which the corresponding information is acquired. . For example, the vehicle information of the correspondence information of the first vehicle V at the point P may have a tendency different from the vehicle information of the correspondence information of the second vehicle V and the third vehicle V at the point P. In this case, the abnormality determining unit 35 determines that there is an abnormality in the first vehicle V from which correspondence information with different trends is obtained.

As described above, in the abnormality determination device 1A, the trend determination unit 34 compares vehicle information pieces of corresponding information acquired at the same position, and determines whether or not the vehicle information shows the same tendency. . For example, when vehicle information changes due to the external environment, vehicle information included in other corresponding information acquired at the same location also changes. Further, when a vehicle abnormality occurs and the vehicle information changes due to the vehicle abnormality, the tendency of the change is different from that of the vehicle information included in other corresponding information acquired at the same location. In other words, the tendency determination unit 34 determines whether or not the vehicle information has changed due to vehicle abnormality by using the tendency of change between vehicle information pieces of corresponding information acquired at the same location. I can do it. If it is determined that the vehicle information has a tendency different from others, the abnormality determination unit 35 determines that there is an abnormality in the vehicle from which the corresponding information including this vehicle information is obtained. In this way, the abnormality determination device 1A can accurately determine the abnormality of the vehicle while suppressing the influence of the external environment.

The vehicle information includes at least one of a detected value of an on-vehicle sensor and an instruction value of a driving operation of the vehicle. In this case, the abnormality determination device 1A can determine, as the abnormality of the vehicle V, an abnormality in at least one of the on-vehicle sensor and the instruction value of the driving operation of the vehicle.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, the determination processing device 20 in the first embodiment may be mounted on the vehicle V. In this case, the determination processing device 20 may determine whether or not there is an abnormality in the vehicle V in which it is mounted, using the correspondence information of other vehicles. Further, the abnormality determination device 1A in the second embodiment may be mounted on the vehicle V. In this case, the abnormality determination device 1A may acquire other vehicle correspondence information and determine whether or not there is an abnormality in the vehicle V in which it is mounted.
