- the device flashes in an emergency flashing state, and both the left and right front turn signals are in a standby state where they are not flashing.
- the alarm device 1 determines whether or not the vehicle A turns based on the information of the vehicle A acquired by various sensors 2. Next, when the alarm device 1 determines that the vehicle A turns, any other vehicle among the plurality of other vehicles is an oncoming vehicle based on the information of the plurality of other vehicles acquired via the communication unit 3. It is determined whether or not the vehicle A is approached. Then, the alarm device 1 outputs an alarm when the vehicle A starts to turn in a situation where another vehicle approaches the vehicle A as an oncoming vehicle. In the following, a case of so-called left-hand traffic, in which a vehicle passes through the left portion from the center of the road, will be described.

- a processor such as a CPU (Central Processing Unit).
- the vehicle information acquisition unit 121 sequentially acquires the information of the vehicle A detected by the various sensors 2. For example, the vehicle information acquisition unit 121 acquires the vehicle speed of the vehicle A and the yaw rate of the vehicle A. Further, the vehicle information acquisition unit 121 acquires the coordinates indicating the position of the vehicle A and the azimuth angle of the vehicle A.

- the right turn determination unit 122 determines that the vehicle A makes a right turn when the direction indicator 4 is in the right turn instruction state and the vehicle speed of the vehicle A is equal to or less than the slow-moving vehicle speed.
- FIG. 2 is a diagram schematically showing the time change of the vehicle speed when the vehicle A turns right.
- the horizontal axis of FIG. 2 indicates the time t, and the vertical axis indicates the vehicle speed V.
- the right turn determination unit 122 determines that the vehicle A makes a right turn when the direction indicator 4 is in the right turn instruction state after the time t1 when the vehicle speed V becomes the slow vehicle speed M.
- the driving vehicle speed M is, for example, a vehicle speed that can be stopped within 1 meter.
- the specific value of the vehicle speed that can be stopped within 1 meter is, for example, 10 kilometers per hour.
- the right turn determination unit 122 may determine that the turn signal 4 is in the right turn instruction state, the vehicle speed V is the slow vehicle speed M or less, and the vehicle turns right when a predetermined condition is satisfied. For example, the right turn determination unit 122 may determine whether or not the vehicle A makes a right turn based on the state of the shift lever of the vehicle A. In this case, the vehicle information acquisition unit 121 acquires the state of the shift lever of the vehicle A. Then, in the right turn determination unit 122, when the direction indicator 4 is in the right turn instruction state, the vehicle speed V is the slow-moving vehicle speed M or less, the direction indicator 4 is in the right turn instruction state, and the vehicle speed is the slow-moving vehicle speed M or less.
- the right turn determination unit 122 determines whether the vehicle A makes a right turn. If the state in which the shift lever is in the drive position continues from before, it is determined that the vehicle A makes a right turn.
- the position of the shift lever is once different from the drive position (for example, the neutral position or the parking position). If so, it is determined that the vehicle A does not turn right. As described above, when the shift lever is in the neutral position or the parking position different from the drive position, it is considered that the vehicle stops, so that the right turn determination unit 122 can determine that the vehicle does not turn right.
- the predetermined vehicle speed N is, for example, 3 kilometers per hour. Specifically, after determining that the vehicle A makes a right turn, the right turn determination unit 122 continues to determine that the vehicle A makes a right turn from the time t2 when the vehicle speed V becomes the predetermined vehicle speed N or less until the predetermined time elapses. .. Then, the right turn determination unit 122 determines that the vehicle A does not turn right after the predetermined time has elapsed.
- the predetermined time may be determined based on, for example, the time during which the display of the signal lamp of the traffic light makes a round, and the specific value of the predetermined time is, for example, 150 seconds.
- the right turn determination unit 122 erroneously determines that the vehicle A makes a right turn when the vehicle A has been stopped for a longer time than when the vehicle has stopped waiting for a traffic light and the probability that the vehicle A will make a right turn is low. Can be suppressed.
- the right turn determination unit 122 determines that the vehicle A will not make a right turn even if the turn signal 4 is in the right turn instruction state and the vehicle speed V is a slow vehicle speed M or less, in a situation where the probability that the vehicle A will make a right turn is low. For example, in the right turn determination unit 122, the turn signal 4 is in the left turn instruction state before the turn signal 4 is in the right turn instruction state and the vehicle speed V becomes the slow-moving vehicle speed M or less. If it is in the blinking state, it is determined that the vehicle A does not turn right. As shown in FIG. 2, when the turn signal 4 is in the left turn instruction state or the emergency blinking state even once at the time after the time t1 when the vehicle speed V becomes the slow vehicle speed M or less, the vehicle A Judges not to turn right.
- the right turn determination unit 122 makes a right turn when the vehicle A changes its course (for example, when the vehicle A moves to the left and then returns to avoid an obstacle on the right side of the vehicle A). It can be determined not to. Further, the right turn determination unit 122 determines that the vehicle A, which has been stopped on the shoulder of the road, does not make a right turn even when the vehicle A starts traveling. Specifically, the right turn determination unit 122 determines that the vehicle A, which has been stopped with the hazard switch turned on and the turn signal 4 in an emergency blinking state, starts traveling, does not make a right turn. As a result, the right turn determination unit 122 can suppress the determination that the vehicle A makes a right turn in a situation other than a right turn, such as when the vehicle A changes its course or when the stopped vehicle A starts traveling.
- the other vehicle information acquisition unit 123 acquires information on the other vehicle from the other vehicle traveling around the vehicle A via the communication unit 3 via vehicle-to-vehicle communication. Specifically, the other vehicle information acquisition unit 123 acquires the vehicle speed of the other vehicle and the coordinates and the azimuth indicating the position of the other vehicle detected by the other vehicle.
- the oncoming vehicle approach determination unit 124 determines whether or not any of the other vehicles existing in the vicinity of the vehicle A approaches the vehicle A as an oncoming vehicle. For example, when the vehicle A turns right, the oncoming vehicle approach determination unit 124 determines whether or not the other vehicle traveling around the vehicle A approaches the vehicle A as an oncoming vehicle based on the information of the other vehicle. Specifically, the oncoming vehicle approach determination unit 124 intersects the vehicle travel vector indicating the direction in which the vehicle A turning right and the other vehicle travel vector indicating the direction in which the other vehicle travels, and the vehicle A When the other vehicle is present in front of the traveling direction, it is determined that the other vehicle approaches the vehicle A as an oncoming vehicle.
- FIG. 3 is a diagram for explaining a process of determining whether another vehicle approaches the vehicle A as an oncoming vehicle.
- the other vehicle B will be described as an example of the other vehicle, but the same processing will be performed for the other vehicle C shown in FIG.
- the oncoming vehicle approach determination unit 124 generates the vehicle traveling vector RA from the position PA of the vehicle A to the right toward the direction indicated by the azimuth angle of the vehicle A (hereinafter referred to as the vehicle facing LA).
- the position PA that is the starting point of the vehicle traveling vector RA is the position of the GPS receiver mounted on the vehicle A.
- the oncoming vehicle approach determination unit 124 generates a vehicle traveling vector RA having a predetermined length from the position PA of the vehicle A in the direction of 90 degrees to the right with respect to the vehicle facing LA.
- the specific value of the predetermined length may be appropriately set, for example, 10 meters.
- the oncoming vehicle approach determination unit 124 sets the average of the directions indicated by the plurality of azimuth angles of the vehicle A detected in the past as the vehicle facing LA. For example, the oncoming vehicle approach determination unit 124 sets the direction indicated by the average value of the plurality of azimuth angles of the vehicle A detected within 30 meters from the position PA of the vehicle A as the vehicle facing LA. The azimuth angle of the vehicle A is detected every 2 meters. By doing so, the oncoming vehicle approach determination unit 124 can more appropriately identify the direction of the vehicle A, for example, when the road is curved.
- the oncoming vehicle approach determination unit 124 generates another vehicle traveling vector RB from the position PB of the other vehicle B along the direction indicated by the azimuth angle of the other vehicle B (hereinafter referred to as LB for the other vehicle). For example, the oncoming vehicle approach determination unit 124 generates another vehicle traveling vector RB having a predetermined length from the position PB of the other vehicle B. Specifically, the oncoming vehicle approach determination unit 124 generates another vehicle traveling vector RB having a value obtained by multiplying the vehicle speed of the other vehicle B by a predetermined time as a predetermined length.
- the position PB that is the starting point of the other vehicle traveling vector RB is the position of the GPS receiver mounted on the other vehicle B.
- the specific value of the predetermined time may be appropriately set, for example, 5 seconds.
- the oncoming vehicle approach determination unit 124 determines whether or not the generated vehicle travel vector RA and the other vehicle travel vector RB intersect.
- the oncoming vehicle approach determination unit 124 determines whether or not the vehicle traveling vector RA and the other vehicle traveling vector RB intersect when the LB facing the other vehicle is in the opposite direction to the LA facing the vehicle. May be good. Specifically, when the oncoming vehicle approach determination unit 124 is within the direction determination range D based on the azimuth angle indicating the vehicle-oriented LA, the other-vehicle-oriented LB is opposite to the vehicle-oriented LA. Judge that there is.
- the orientation determination range D is a range of plus 135 degrees to 225 degrees with respect to the azimuth angle indicating the vehicle orientation LA.
- the oncoming vehicle approach determination unit 124 determines the LB for the other vehicle. It may be determined that it is the opposite of the vehicle-oriented LA. In this case, the oncoming vehicle approach determination unit 124 sets the direction indicated by the average value of the azimuth angles of the 10 other vehicles B acquired immediately before as the other vehicle facing LB. By doing so, the oncoming vehicle approach determination unit 124 can more appropriately detect the direction of another vehicle, for example, when the road is curved.
- the orientation determination range D is a range filled with diagonal lines rising to the right. Since the oncoming vehicle approach determination unit 124 includes the other vehicle-oriented LB of the other vehicle B in the orientation determination range D, the oncoming vehicle approach determination unit 124 determines that the other vehicle-oriented LB of the other vehicle B is in the opposite direction to the vehicle-oriented LA. On the other hand, the oncoming vehicle approach determination unit 124 determines that the LC facing the other vehicle of the other vehicle C is not included in the orientation determination range D, and therefore the LC facing the other vehicle of the other vehicle C is not in the opposite direction to the LA facing the vehicle.
- the oncoming vehicle approach determination unit 124 determines whether or not another vehicle exists in front of the vehicle A in the traveling direction. For example, when the position of the other vehicle is included in the predetermined angle range E including the vehicle facing LA, the oncoming vehicle approach determination unit 124 determines that the other vehicle B exists in front of the vehicle A in the traveling direction.
- the predetermined angle range E is, for example, a range of minus 75 degrees to plus 75 degrees with respect to the azimuth angle indicating the vehicle-oriented LA. In FIG. 3, the predetermined angle range E is a range filled with diagonal lines downward to the right. Since the position PB of the other vehicle B is included in the predetermined angle range E, the oncoming vehicle approach determination unit 124 determines that the other vehicle B exists in front of the vehicle A in the traveling direction. On the other hand, the oncoming vehicle approach determination unit 124 determines that the other vehicle C does not exist in front of the vehicle A in the traveling direction because the position PC of the other vehicle C is not included in the predetermined angle range E.
- the exclusion determination range is, for example, a range of minus 135 degrees to plus 135 degrees with respect to the azimuth angle indicating the vehicle-oriented LA.
- the oncoming vehicle approach determination unit 124 may determine whether or not the other vehicle B approaches the vehicle A as an oncoming vehicle when the accuracy of the position and the accuracy of the azimuth are high.
- the vehicle information acquisition unit 121 acquires the detection accuracy of the position PB of the vehicle A and the detection accuracy of the azimuth angle from the various sensors 2.
- the vehicle information acquisition unit 121 acquires any value from 0 to 15 as the detection accuracy of the position PB of the vehicle A. It is assumed that the larger the number, the higher the accuracy of the detection accuracy. It is assumed that the azimuth detection accuracy is the same as the position detection accuracy.
- the other vehicle information acquisition unit 123 acquires the detection accuracy of the position PB of the other vehicle B and the detection accuracy of the azimuth angle from the other vehicle B via vehicle-to-vehicle communication.
- Each of the detection accuracy of the position PB of the other vehicle B and the detection accuracy of the azimuth angle is the same as the detection accuracy of the position PB of the vehicle A and the detection accuracy of the azimuth angle.
- the detection accuracy of the position PA of the vehicle A and the detection accuracy of the position PB of the other vehicle B are equal to or higher than the position accuracy determination threshold value, and the detection accuracy of the azimuth of the vehicle A and the other vehicle B
- the azimuth detection accuracy of is equal to or higher than the azimuth accuracy determination threshold value
- the specific value of the position accuracy determination threshold value is, for example, 10.
- the specific value of the azimuth accuracy determination threshold value is, for example, 4.
- the oncoming vehicle approach determination unit 124 does not determine whether or not the other vehicle B approaches when either the position accuracy or the azimuth accuracy is relatively low. It is possible to suppress erroneous judgment due to relatively low accuracy.
- the oncoming vehicle approach determination unit 124 the vehicle traveling vector RA and the other vehicle traveling vector RB intersect, the vehicle facing LA and the other vehicle facing LB are in opposite directions, and the other vehicle B is in front of the vehicle A in the traveling direction. Is present, it is determined that the other vehicle B approaches the vehicle A as an oncoming vehicle to the vehicle A. By doing so, the oncoming vehicle approach determination unit 124 can exclude the other vehicle C that does not approach the vehicle A as an oncoming vehicle. The probability of identifying another vehicle B approaching can be increased.
- the output control unit 125 issues an alarm indicating that the other vehicle B is approaching the vehicle A as an oncoming vehicle when the vehicle A starts turning right.
- Output to 10 For example, when the yaw rate of the vehicle A detected by the vehicle information acquisition unit 121 is equal to or higher than a predetermined angular velocity, it is determined that the vehicle A has started a right turn, and the alarm output unit 10 is made to output an alarm.
- the predetermined angular velocity may be appropriately set by an experiment or the like, and is, for example, 1.5 degrees per second.
- the output control unit 125 issues an alarm when the accelerator opening of the vehicle A is larger than the predetermined opening and the yaw rate becomes equal to or higher than the predetermined angular velocity when the other vehicle B approaches the vehicle A as an oncoming vehicle. It may be output.
- the vehicle information acquisition unit 121 acquires the accelerator opening degree of the vehicle A.
- the predetermined opening may be set as a value at which it can be determined that the driver has depressed the accelerator pedal.
- the specific value of the predetermined opening degree is, for example, 5% when the state where the pedal is fully depressed is 100%.
- the output control unit 125 will start turning right when the driver of the vehicle A depresses the accelerator pedal even though the other vehicle B is approaching the vehicle A as an oncoming vehicle.
- the alarm output unit 10 can output an alarm.
- the output control unit 125 outputs an alarm when the temporarily stopped vehicle A starts to turn right when the other vehicle B is approaching the vehicle A as an oncoming vehicle.
- the vehicle information acquisition unit 121 further acquires the brake state of the vehicle A.
- the output control unit 125 determines that the vehicle A makes a right turn and the other vehicle B approaches the vehicle A as an oncoming vehicle, the braking state is on and the vehicle speed is equal to or lower than the predetermined speed. Is determined.
- the predetermined speed is a value at which it can be determined that the vehicle A has temporarily stopped.
- the specific value that can be determined to be paused is, for example, 3 km / h, but may be 0 km / h.
