Embodiments for Carrying Out the Invention

[0008] Assume a case where a vehicle user activates the vehicle's blinker to change lanes or overtake another vehicle. In this case, when canceling the lane change or overtaking, the operation of the blinker for lane change or overtaking is terminated. Then, the operation time of the blinker may be short from the time when the blinker is activated for lane change or overtaking until the operation of the blinker is terminated along with the cancellation of the lane change or overtaking. The operation time of the blinker may become short until the operation of the blinker is terminated along with the cancellation of the lane change or overtaking after the blinker is activated for lane change or overtaking.

[0009] Also, consider a case where a vehicle user activates the vehicle's turn signal to make a right or left turn (right or left turn). At this time, the vehicle user may turn the steering wheel in the opposite direction of the turn to perform corrective steering before completing the turn, causing the turn signal to turn off. In this case, the vehicle user reactivates the turn signal before completing the turn. In this case, it is assumed that the time from reactivating the turn signal to completing the turn and turning off the turn signal (turn signal activation time) will be shortened. In this way, it is assumed that the shortened turn signal activation time during a turn is caused by the turn signal being reactivated after it was turned off due to corrective steering when the vehicle was turning right or left.

[0010] In addition, when a vehicle cancels a lane change or overtaking attempt, the activation time of the vehicle's turn signal may fall below the threshold. Furthermore, when the vehicle makes a corrective steering maneuver to turn right or left, the turn signal may be turned off and then reactivated, causing the turn signal to unintentionally fall below the threshold. Here, the activation time threshold is a sufficient time for the turn signal to be activated. In these cases, it is unreasonable for the user to receive activation information indicating that the turn signal activation time is below the threshold.

[0011] On the other hand, when a vehicle cancels a lane change or overtaking, the vehicle user interrupts the steering operation for the lane change or overtaking. Therefore, it is assumed that the amount of steering operation by the vehicle user is smaller than when the vehicle changes lanes or overtakes. Also, it is assumed that the vehicle speed when turning right or left is slower than when the vehicle is not turning right or left. Therefore, it is possible to detect that the vehicle has canceled a lane change or overtaking, or that the vehicle is turning right or left, when predetermined conditions related to at least one of the steering angle and speed of the vehicle are satisfied.

[0012] Therefore, the control unit of the information processing apparatus according to the present disclosure acquires the operation time of the vehicle's blinker. Then, when the operation time of the vehicle's blinker is equal to or less than a threshold value and at least one predetermined condition regarding at least one of the vehicle's steering angle and the vehicle's speed is satisfied, the control unit of the information processing apparatus according to the present disclosure omits outputting operation information. Further, when the operation time of the vehicle's blinker is equal to or less than a threshold value and a predetermined condition is not satisfied, the control unit outputs operation information.

[0013] As described above, the information processing apparatus determines whether or not at least one predetermined condition regarding at least one of the steering angle or the speed of the vehicle is satisfied when the operation time of the blinker is equal to or less than a threshold value. Thereby, it is possible to determine whether the operation time of the blinker has become equal to or less than the threshold value due to the vehicle stopping a lane change or overtaking, or due to the blinker being reactivated after being turned off during a corrective steering when turning right or left of the vehicle. And when it can be determined that the output of the operation information is unreasonable for the user because the operation time of the blinker has become equal to or less than the threshold value for these reasons, the output of the operation information is omitted. In this way, it is possible to appropriately notify the short-time operation of the vehicle's blinker.

[0014] Hereinafter, specific embodiments of the present disclosure will be described with reference to the drawings. The hardware configuration, module configuration, functional configuration, etc. described in each embodiment are not intended to limit the technical scope of the disclosure only to those, unless otherwise specified.

[0015] <Embodiment> (Overview of the System) The evaluation system 1 in the present embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram showing a schematic configuration of the evaluation system 1. The evaluation system 1 includes an in-vehicle device 100 and a driving ECU 200. In the evaluation system 1, the in-vehicle device 100 and the driving ECU 200 are interconnected by an in-vehicle network.

[0016] (Driving ECU) The traveling ECU 200 is an electronic control unit that controls the traveling of the vehicle 10. The traveling ECU 200 transmits, in real time, the traveling information of the vehicle 10 to the in-vehicle device 100 via the in-vehicle network. Here, the traveling information of the vehicle 10 includes information indicating the speed of the vehicle 10. Further, the traveling information of the vehicle 10 includes information indicating the steering angle of the vehicle 10. Further, when the turn signal of the vehicle 10 starts operating, the traveling ECU 200 transmits to the in-vehicle device 100 the traveling information including information indicating that the turn signal of the vehicle 10 has started operating. Further, when the turn signal of the vehicle 10 ends operating, the traveling ECU 200 transmits to the in-vehicle device 100 the traveling information including information indicating that the turn signal of the vehicle 10 has ended operating. The information indicating that the turn signal of the vehicle 10 has started or ended operating includes information indicating the time when the turn signal of the vehicle 10 has started or ended operating.

[0017] (In-vehicle device) The in-vehicle device 100 is a device mounted on the vehicle 10. The in-vehicle device 100 performs outputs (display on the display, voice output, etc.) according to various information for the user of the vehicle 10. Further, the in-vehicle device 100 receives, in real time, the traveling information of the vehicle 10 from the vehicle 10 via the in-vehicle network. The in-vehicle device 100 refers to the traveling information of the vehicle 10 and monitors, in real time, the traveling state of the vehicle 10 (the speed of the vehicle 10, the steering angle, and the presence or absence of the operation of the turn signal).

[0018] The in-vehicle device 100 refers to the traveling state of the vehicle 10 and measures the operation time of the turn signal of the vehicle 10. When the operation time of the turn signal is less than or equal to an appropriate time as the operation time of the turn signal, the driving of the user of the vehicle 10 may not be appropriate. Therefore, the in-vehicle device 100 may output operation information when the operation time of the turn signal is less than or equal to the threshold value.

[0019] Here, the threshold value of the operation time is a sufficient time as the operation time of the blinker. In the present embodiment, a fixed value is set as the threshold value of the operation time. The threshold value of the operation time is, for example, a legally defined time as the time for operating the blinker when the vehicle changes lanes or overtakes, or turns right or left. Further, the threshold value of the operation time may be a variable value. Also, in the present embodiment, the operation information is information for notifying the user of the vehicle 10 that the operation time of the blinker was below the threshold value. The in-vehicle device 100 outputs the operation information to the user of the vehicle 10 by, for example, displaying the operation information on a display or outputting it as sound.

[0020] On the other hand, assume that the in-vehicle device 100 always outputs operation information when the operation time of the blinker is below the threshold value. Then, the operation information is output even when the operation time of the blinker becomes below the threshold value due to force majeure or an unintended reason of the user of the vehicle 10. In this case, it is unreasonable for the user of the vehicle 10.

[0021] Here, assume that the user of the vehicle 10 operates the blinker for lane change or overtaking. In this case, there may be a case where the lane change or overtaking is aborted due to the approach of another vehicle during the lane change or overtaking. At this time, the operation time of the blinker from when the blinker is operated for lane change or overtaking until the operation of the blinker is terminated along with the cancellation of the lane change or overtaking may be below the threshold value.

[0022] Also, assume that the user of the vehicle 10 operates the blinker for a right or left turn. At this time, before the right or left turn of the vehicle 10 is completed, the user of the vehicle 10 may turn the steering wheel in the direction opposite to the right or left turn for corrective steering. In this case, the vehicle 10 makes a right or left turn It is assumed that the vehicle is decelerating for singing. Also, the lower the speed of the vehicle 10, the larger the steering angle required for corrective steering. Therefore, during a right or left turn, in order to perform corrective steering, the steering wheel is turned significantly in the opposite direction to the right or left turn direction. By doing so, when the steering wheel is turned significantly in the opposite direction to the right or left turn direction, the blinker is likely to turn off. Also, when the blinker turns off once, the user of the vehicle 10 reactivates the blinker to complete the right or left turn.

[0023] At this time, there may be a case where the time from when the blinker is reactivated until the right or left turn is completed and the blinker turns off (the operating time of the blinker) is equal to or less than the threshold value. Thus, when the operating time of the blinker becomes equal to or less than the threshold value during a right or left turn of the vehicle, it is assumed that the blinker was reactivated after it turned off due to corrective steering during the right or left turn of the vehicle.

[0024] Thus, when the vehicle 10 activates the blinker for a lane change or overtaking, the operating time of the blinker may become equal to or less than the threshold value due to force majeure such as the approach of another vehicle. Also, when the vehicle 10 activates the blinker to make a right or left turn, the blinker may turn off due to corrective steering, and the operating time of the blinker may become equal to or less than the threshold value for reasons unintended by the user. In these cases, it is unreasonable for the in-vehicle device 100 to output the operation information to the user of the vehicle 10.

[0025] On the other hand, when the vehicle 10 cancels a lane change or overtaking, the user of the vehicle 10 interrupts the steering wheel operation for the lane change or overtaking midway. Therefore, it can be assumed that the amount of steering wheel operation by the user of the vehicle 10 is smaller than when the vehicle 10 actually performs a lane change or overtaking. Also, it can be assumed that the speed of the vehicle 10 when making a right or left turn is lower than when the vehicle 10 is not making a right or left turn. Therefore, the in-vehicle device 100 can detect that the vehicle has canceled a lane change or overtaking or that the vehicle 10 is in the middle of a right or left turn when the steering angle or speed of the vehicle 10 satisfies a predetermined condition.

[0026] In this way, in-vehicle device 100 can determine whether the operation time of the turn signal has become equal to or less than the threshold value due to the vehicle 10 stopping a lane change or overtaking, or due to the turn signal being reactivated after turning off when the vehicle 10 makes a right or left turn and is corrected. When the in-vehicle device 100 determines that it is unreasonable for the user of the vehicle 10 to output the operation information because the operation time of the turn signal has become equal to or less than the threshold value for these reasons, the in-vehicle device 100 omits the output of the operation information. Details of the method by which the in-vehicle device 100 omits the output of the operation information will be described later.

[0027] The in-vehicle device 100 includes a computer having a processor 110, a main storage unit 120, an auxiliary storage unit 130, and a communication interface (communication I / F) 140. The processor 110 is, for example, a CPU (Central Processing Unit) or a DSP (Digital Signal Processor). The main storage unit 120 is, for example, a RAM (Random Access Memory). The auxiliary storage unit 130 is, for example, a ROM (Read Only Memory). Further, the auxiliary storage unit 130 is, for example, an HDD (Hard Disk Drive), or a disk recording medium such as a CD-ROM, a DVD disk, or a Blu-ray disk. Further, the auxiliary storage unit 130 may be a removable medium (portable storage medium). Here, examples of the removable medium include a USB memory or an SD card. The communication I / F 140 is, for example, a LAN (Local Area Network) interface board.

[0028] In the in-vehicle device 100, the auxiliary storage unit 130 stores an operating system (OS), various programs, and various information tables, etc. Further, the in-vehicle device 100 In the in-vehicle device 100, the processor 110 loads a program stored in the auxiliary storage unit 130 into the main storage unit 120 and executes it, thereby realizing various functions as described below. However, some or all of the functions of the in-vehicle device 100 may be realized by a hardware circuit such as an ASIC or an FPGA. Note that the in-vehicle device 100 does not necessarily have to be realized by a single physical configuration, and may be configured by multiple computers that cooperate with each other.

[0029] (Functional configuration) Next, the functional configuration of the in-vehicle device 100 constituting the evaluation system 1 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 is a block diagram showing an example of the functional configuration of the in-vehicle device 100.

[0030] The in-vehicle device 100 includes a control unit 101, a communication unit 102, a steering angle condition database 103 (steering angle condition DB103), and a driving information database 104 (driving information DB104). The control unit 101 has a function of performing arithmetic processing for controlling the in-vehicle device 100. The control unit 101 can be realized by a processor 110 in the in-vehicle device 100. The communication unit 102 has a function of connecting the in-vehicle device 100 to an in-vehicle network. The communication unit 102 can be realized by a communication I / F 140 in the in-vehicle device 100.

[0031] The steering angle condition DB 103 has a function of storing steering angle condition information. The steering angle condition information is information about conditions related to the steering angle for determining whether or not to output operation information. The steering angle condition DB 103 can be realized by the auxiliary storage unit 130 in the in-vehicle device 100. FIG. 3 is a diagram showing an example of a table configuration of the steering angle condition information stored in the steering angle condition DB 103.

[0032] As shown in FIG. 3, the steering angle condition information has a condition ID field, a speed field, and a steering angle field. In the condition ID field, an identifier (condition ID) for identifying a condition related to the steering angle for determining whether to output operation information is stored. In the speed field, information indicating the speed of the vehicle is stored. For example, information indicating the range of the vehicle speed is stored in the speed field.

[0033] Here, the higher the speed of the vehicle, the more necessary it is to drive with a smaller steering angle in order to drive safely. Therefore, the greater the speed of the vehicle, the smaller the change amount of the steering angle during lane change or overtaking. Similarly, the greater the speed of the vehicle, the smaller the change amount of the steering angle when lane change or overtaking is aborted. Therefore, in the steering angle field, a change amount of the steering angle (hereinafter, may be referred to as "threshold value of the change amount") that can be assumed when lane change or overtaking is aborted is stored according to the speed of the vehicle in the corresponding speed field.

[0034] Here, the change amount of the steering angle is determined to be the amount when lane change or overtaking is aborted at low speed, but may be the change amount of the steering angle when lane change or overtaking is not aborted at high speed. In such a case, by setting the threshold value of the change amount to decrease as the speed of the vehicle increases, it is possible to suppress the vehicle 10 traveling at high speed from being determined to have aborted lane change or overtaking when lane change or overtaking is performed. In this way, it is possible to detect that lane change or overtaking has been aborted in response to the change in the steering operation accompanying the increase in the speed of the vehicle. In the present embodiment, the threshold value of the change amount changes according to the speed of the vehicle, but the threshold value of the change amount may be a fixed value.

[0035] The control unit 101 receives the driving information of the vehicle 10 from the driving ECU 200 in real time via the communication unit 102. Specifically, the control unit 101 receives the driving information of the vehicle 10 from the driving EC By repeatedly receiving the information from the U200 at predetermined intervals, the control unit 101 receives the travel information of the vehicle 10 in real time. The control unit 101 stores the received travel information of the vehicle 10 in the travel information DB 104.

[0036] The travel information DB 104 has a function of storing travel information. The travel information DB 104 can be realized by the auxiliary storage unit 130 in the in-vehicle device 100. Figure 4 is a diagram showing an example of a table configuration of travel information stored in the travel information DB 104.

[0037] The driving information has a date and time field, a speed field, a steering angle field, and a blinker field. The date and time field stores information indicating the date and time when the driving information was transmitted.

[0038] The speed field stores information indicating the speed of the vehicle 10 at the date and time the driving information was transmitted. The steering angle field stores information indicating the steering angle of the vehicle 10 at the date and time the driving information was transmitted. The blinker field stores information indicating the blinker operation status at the date and time the driving information was transmitted. If the received driving information includes information indicating that the blinkers of the vehicle 10 have started to operate, the blinker field stores the information "operation started." If the received driving information includes information indicating that the blinkers of the vehicle 10 have stopped operating, the blinker field stores the information "operation stopped." If the received driving information does not include either information indicating that the blinkers of the vehicle 10 have started to operate or information indicating that the blinkers of the vehicle 10 have stopped operating, the information "----" is stored.

[0039] When the received driving information includes information indicating that the turn signal of the vehicle 10 has started to operate, the control unit 101 starts measuring time. When the received driving information includes information indicating that the turn signal of the vehicle 10 has ended its operation, the control unit 101 ends the time measurement. In this way, the control unit 101 measures the operation time of the turn signal. Then, the control unit 101 determines whether the measured operation time of the turn signal is less than or equal to a threshold value.

[0040] When the measured operation time of the turn signal is less than or equal to the threshold value, the control unit 101 acquires the speed of the vehicle 10 at the date and time when the vehicle 10 started the operation of the turn signal from the driving information of the vehicle 10 held in the driving information DB 104. Here, when the turn signal is reactivated during a right / left turn, it can be assumed that the vehicle 10 has decelerated sufficiently. Therefore, by acquiring the speed of the vehicle 10 at the date and time when the vehicle 10 started the operation of the turn signal, it is possible to determine whether the vehicle 10 reactivated the turn signal during a right / left turn.

[0041] The control unit 101 determines whether the acquired speed of the vehicle 10 is less than or equal to a predetermined speed. When the acquired speed of the vehicle 10 is less than or equal to the predetermined speed, it is assumed that the turn signal has turned off due to the corrective steering during the right / left turn of the vehicle 10, and the operation time of the reactivated turn signal has become shorter. Therefore, the control unit 101 omits the output of the operation information. Here, the predetermined speed is a speed at which it is assumed that the vehicle 10 is making a right / left turn. The predetermined speed is, for example, a creeping speed. In addition, when it is assumed that a right / left turn is made at a speed higher than the creeping speed depending on the road, the predetermined speed does not have to be the creeping speed.

[0042] Furthermore, if the acquired speed of the vehicle 10 is not equal to or less than a predetermined speed, the control unit 101 calculates, from the driving information stored in the driving information DB 104, the amount of change in the steering angle from when the turn signal of the vehicle 10 starts to operate until the turn signal stops operating. The control unit 101 then determines whether the calculated amount of change in the steering angle is equal to or less than a threshold. If the calculated amount of change in the steering angle is equal to or less than the threshold, it is assumed that the user of the vehicle 10 has stopped changing lanes or overtaking. Therefore, the control unit 101 omits output of the operation information.

[0043] Here, the steering angle is defined as a negative value when the steering wheel or tires are not turned (steer angle is 0 degrees), and a positive value when the steering angle is turned to the right. Therefore, the amount of change in steering angle is calculated as the absolute value of the difference between the maximum steering angle and the minimum steering angle from the time the turn signal starts to operate to the time the turn signal stops operating.

[0044] (flowchart) Next, the processing executed by the control unit 101 in the in-vehicle device 100 in the evaluation system 1 will be described with reference to Fig. 5. Fig. 5 is a flowchart of the processing executed by the control unit 101. The processing shown in Fig. 5 is processing for outputting activation information. Execution of the processing shown in Fig. 5 starts when the control unit 101 completes measurement of the activation time of the blinker of X10.

[0045] In the process shown in Fig. 5, first, in S101, the measured activation time is acquired. Next, in S102, it is determined whether the acquired activation time is equal to or less than a threshold value. If the determination in S102 is negative, the blinker activation time is sufficient, and therefore there is no need to output activation information. Therefore, the process shown in Fig. 5 is terminated.

[0046] If a positive determination is made in S102, then in S103, the speed of the vehicle 10 at the date and time when the vehicle 10 started operating its turn signal is acquired from the travel information stored in the travel information DB 104. Next, in S104, it is determined whether the acquired speed of the vehicle 10 is equal to or less than a predetermined speed. If a positive determination is made in S104, it is assumed that the reason why the turn signal activation time was determined to be equal to or less than the threshold is that the turn signal was turned off due to corrective steering while the vehicle 10 was turning right or left, and the activation time of the turn signal when it was reactivated was shortened. Therefore, it would be unreasonable for the user of the vehicle 10 to have the activation information output. Therefore, if a positive determination is made in S104, the output of the activation information is omitted, and the processing shown in FIG. 5 is terminated.

[0047] If a negative determination is made in S104, then in S105, the amount of change in the steering angle from when the turn signal of the vehicle 10 starts to operate until the turn signal of the vehicle 10 stops operating is acquired. Next, in S106, it is determined whether the acquired amount of change in the steering angle is equal to or less than a threshold. If a positive determination is made in S105, it is assumed that the user of the vehicle 10 has stopped changing lanes or overtaking. Therefore, it would be unreasonable for the user of the vehicle 10 to have the activation information output. Therefore, if a positive determination is made in S105, the output of the activation information is omitted, and the processing shown in FIG. 5 is terminated.

[0048] If a negative determination is made in S106, the fact that the blinker activation time is equal to or less than the threshold does not mean that the activation time of the blinker that was reactivated when turning right or left has become shorter, nor that a lane change or overtaking attempt has been canceled. Therefore, it is not unreasonable for the user of the vehicle 10 even if activation information is output. Therefore, if a negative determination is made in S106, activation information is output in S107. Then, the processing shown in FIG. 5 ends.

[0049] As described above, in the evaluation system 1, when the operation time of the turn signal becomes equal to or less than the threshold value, it is determined whether the steering angle or the speed of the vehicle 10 satisfies a predetermined condition. As a result, it is possible to determine whether the operation time of the turn signal has become equal to or less than the threshold value due to the vehicle 10 stopping a lane change or an overtaking, or due to the turn signal being re-activated during a right or left turn of the vehicle 10. And when it can be determined that the output of the operation information is unreasonable for the user of the vehicle 10 because the operation time of the turn signal has become equal to or less than the threshold value for these reasons, the output of the operation information is omitted. In this way, the short-time operation of the turn signal of the vehicle can be appropriately notified.

[0050] (Modification Example 1) In the present embodiment, the operation information is information for notifying the user of the vehicle 10 that the operation time of the turn signal is equal to or less than the threshold value. Further, the in-vehicle device 100 outputs the operation information to the user of the vehicle 10. The operation information may be information for notifying an external server that the operation time of the turn signal is equal to or less than the threshold value. In this case, the in-vehicle device 100 outputs (transmits) the operation information to the external server via a telephone communication network such as a mobile phone. Here, the external server is, for example, a server that evaluates the driving of the user of the vehicle 10.

[0051] At this time, the operation information includes information indicating the measured operation time of the turn signal together with information indicating that the operation time of the turn signal is equal to or less than the threshold value. The external server refers to the information indicating the measured operation time of the turn signal included in the operation information and evaluates the driving of the user of the vehicle 10. In this way, the short-time operation of the turn signal of the vehicle can be appropriately notified to the external server. Note that the in-vehicle device 100 may output the operation information (information for notifying the user of the vehicle 10 that the operation time of the turn signal is equal to or less than the threshold value) to the user and output the operation information (information including information indicating the measured operation time of the turn signal) to the external server.

[0052] (Modification Example 2) In this embodiment, in-vehicle device 100 determines whether to output operation information. However, an external device other than in-vehicle device 100 may determine whether to output operation information. In this case, the external device acquires driving information from in-vehicle device 100 via a telephone communication network such as a mobile phone. Then, the external device may refer to the driving information and determine whether to output (transmit) the operation information to in-vehicle device 100. Here, when in-vehicle device 100 receives the operation information, it outputs a notification to the user of vehicle 10 that the operation time of the turn signal was below the threshold value. Even in this way, it is possible to appropriately notify the short-time operation of the turn signal of the vehicle.

[0053] (Modification Example 3) In this embodiment, the threshold value of the operation time is a fixed time. On the other hand, in this modification example, the threshold value of the operation time is changed according to the speed of vehicle 10. Specifically, the lower the speed of vehicle 10, the smaller the threshold value of the operation time is set.

[0054] Here, the lower the speed of vehicle 10, the larger the steering angle required for corrective steering. Therefore, the lower the speed of vehicle 10, the easier it is for the turn signal to turn off due to corrective steering. Therefore, by making the threshold value of the operation time smaller as the speed of vehicle 10 decreases, it is possible to suppress the output of operation information even when the time (operation time) from the re-operation of the turn signal to the completion of a right or left turn becomes short.

[0055] When the operation of the turn signal ends, in-vehicle device 100 acquires the speed of vehicle 10 at the start of the operation of the turn signal. Then, in-vehicle device 100 determines the threshold value of the operation time according to the acquired speed of vehicle 10. In this case, as the speed below a predetermined speed decreases, the threshold value of the operation time is determined to become smaller. Also, when the speed is higher than the predetermined speed, the threshold value of the operation time is determined to be a fixed value. And when the operation time of the turn signal is below the threshold value and the speed of vehicle 10 is below the predetermined speed, the output of the operation information is omitted.

[0056] In addition, when a threshold value corresponding to a speed equal to or lower than a predetermined speed is determined as the threshold value of the operation time, the determination as to whether or not the speed of the vehicle 10 is equal to or lower than the predetermined speed may be omitted. Also, when the speed of the vehicle 10 is equal to or lower than the predetermined speed, by setting the threshold value of the operation time to 0, the determination as to whether or not the speed of the vehicle 10 is equal to or lower than the predetermined speed may be omitted when the speed of the vehicle 10 is equal to or lower than the predetermined speed. Even in this case, it is possible to appropriately notify short-time operation of the vehicle's blinker.
