Next, the operation will be described.
FIG. 4 is a flowchart showing the operation of the driving support apparatus according to this embodiment. Hereinafter, the operation will be described according to this flowchart.
In the driving support device of this embodiment, the training vehicle identification information, the training vehicle information, and the alarm information are transmitted and received between the training vehicle and a general vehicle that travels around the training vehicle, and the training vehicle is on the traveling road. Announcement and warning for driving support for the situation where the vehicle and the general vehicle approach or the driving route crosses each other is performed in advance in the general vehicle and the learning vehicle that run around the learning vehicle. Driving assistance for ensuring safety is provided to drivers of ordinary vehicles and the training vehicle.
FIG. 3 is a plan view showing a two-lane road on which the training vehicle 103 and the general vehicles 101 and 102 travel. In the lane 201 on the low speed side, the training vehicle 103 and the general vehicle 101 are traveling behind the training vehicle 103. The training vehicle 103 is being trained, the trainees drive, and an instructor is on the passenger seat. Then, when the instructor in the passenger seat operates the operation switch for setting the driver specific information, it is set that the driver is a “teacher” as the driver specific information. A general vehicle 102 is traveling in the high-speed lane 202, and the general vehicle 102 travels in the high-speed lane 202 in the vicinity of an intermediate position between the training vehicle 103 traveling in the adjacent lane 201 and the general vehicle 101. ing. Furthermore, the distance between the training vehicle 103 and the general vehicle 101 and the distance between the training vehicle 103 and the general vehicle 102 are within 100 meters, and they are traveling in a communicable area.
In the situation shown in FIG. 3, inter-vehicle communication is performed between the training vehicle 103 and the general vehicle 101 and between the training vehicle 103 and the general vehicle 102.

In the training vehicle 103, the ECU 55 collects training vehicle state information indicating the state of the host vehicle at a predetermined cycle (step S1).
Then, based on the driver identification information set by the driver identification information setting unit 57 of the collected learning vehicle state information, the driver determination unit 61 determines whether or not the driver is a trainee (step S2).
When it is determined that the driver is a trainee, the ECU 55 trains train vehicle information to be transmitted to the approaching general vehicles 101 and 102 based on the train vehicle state information collected in the step S1. (Step S3), and the training vehicle identification information and the generated training vehicle information are transmitted to the general vehicles 101 and 102 by the inter-vehicle communication device 54 (step S4).

The general vehicles 101 and 102 receive the training vehicle identification information and the training vehicle information transmitted from the training vehicle 103 by the inter-vehicle communication device 1. The ECU 3 determines whether or not the vehicle traveling in the communicable area is a training vehicle based on the training vehicle identification information transmitted from the training vehicle 103 (step S10). As a result, if it is determined that the vehicle traveling in the communicable area of the own vehicle is a training vehicle, it is subsequently determined whether the training vehicle information has been received (step S11).
As a result, if it is determined that the training vehicle information has been received, it is further determined whether or not the training vehicle and the host vehicle are approaching (step S12).
The determination as to whether or not the learning vehicle and the own vehicle are approaching each other is based on the position information and speed information of the learning vehicle 101 in the received learning vehicle information, and the general vehicle 101 when the learning vehicle information is received. Alternatively, it is performed by determining whether or not the distance between the training vehicle 103 and the host vehicle changes in a direction in which the distance between the training vehicle 103 and the host vehicle is reduced based on the position information and speed information of the host vehicle that is the general vehicle 102.
In the general vehicle 101, when the training vehicle information is received, the inter-vehicle distance changing means 13 of the ECU 3 presets the inter-vehicle distance with the vehicle ahead in the same lane by engine control and brake control by the inter-vehicle distance control system 4. The distance is changed to a longer distance than the current value, and the distance between the host vehicle and the training vehicle 103 is controlled to be longer than a preset value (step S13).
In the general vehicles 101 and 102, when the ECU 3 determines that the training vehicle 103 and the own vehicle are approaching, the display unit 6 and the voice are recognized in a form that allows the presence of the training vehicle 103 to be visually or audibly recognized. The output unit 7 notifies the driver of the host vehicle, for example, “Training vehicle is traveling around. Please be careful” or the like (step S14).

Next, in the general vehicles 101 and 102, the intersection determination unit 12 of the ECU 3 determines the possibility of intersection with respect to the travel route between the training vehicle 103 and the host vehicle (step S15). The determination of the possibility of crossing is made by determining the position information of the learning vehicle 103, the position information of the own vehicle that is the general vehicles 101 and 102, the situation of the turn signal operation of the learning vehicle 103 and the own vehicle, the traveling speed of the learning vehicle 103 and the own vehicle. Based on the information, when the own vehicle is operating behind the training vehicle 103 in the same lane behind the training vehicle 103, or when the own vehicle overtakes the training vehicle 103, or the neighboring vehicle is a training vehicle. When the host vehicle is operating in parallel with the vehicle 103 and the turn signal is changed to the driving lane of the training vehicle 103, the driving route between the host vehicle and the training vehicle 103 is likely to be mixed. judge. As a result, when it is determined that there is a high possibility that the traveling route between the host vehicle and the training vehicle 103 is mixed, the ECU 3 uses the display control unit 21 and the speech control unit 22 of the car navigation system 5 to the driver of the host vehicle. Alarm display for alerting from the display unit 5 and the audio output unit 6 and, for example, “pass the training vehicle. Be careful of the movement of the training vehicle”, “the training vehicle changes lanes to the right lane "Please be careful" is performed (step S16).
In step S16, “right turn signal operation” or “left turn signal operation” in the turn signal operation information of the learning vehicle information received from the learning vehicle 103, and the traveling speed information of the learning vehicle 103 and the host vehicle “ The driver of the vehicle is giving an announcement such as “The training vehicle ahead of 100 meters is waiting for a right turn. Please be careful” or “The training vehicle ahead of 100 meters is waiting for a left turn. On the other hand, the display control means 21 and the speech control means 22 of the car navigation system 5 may output a warning from the display unit 5 and the voice output unit 6.
Then, the warning for calling attention to the training vehicle 103 is transmitted from the inter-vehicle communication device 1 to the training vehicle 103 (step S17).

  In the training vehicle 103, it is determined whether or not an alarm for alerting transmitted from the general vehicle 101 or the general vehicle 102 in the communicable area has been received by the inter-vehicle communication device 54 (step S5). When the warning is received, the received warning is visually displayed and output to the passenger seat warning display unit 56 (step S6).

In the embodiment described above, regarding the power supply of the driving support device for the learning vehicle and the driving support device for the general vehicle, the power supply from the in-vehicle battery is applied even if the learning vehicle and the general vehicle are in the engine stop state. The supply is ensured.
Alternatively, in the case of a training vehicle, if it is a vehicle that employs a manual mission mechanism, a mechanism for avoiding engine stop due to a sudden braking operation by a trainee in the driver's seat, for example, an instructor in the passenger seat A configuration may be adopted in which the clutch is interlocked by the operation of the auxiliary brake operated by the operation to avoid the engine stop.

  As described above, according to this embodiment, even if the driver of a general vehicle is not aware of the training vehicle ahead and the training vehicle in the adjacent lane, the presence of the training vehicle around the subject vehicle, the training vehicle Training vehicle information about the behavior of the vehicle and the state of the training vehicle can be grasped by inter-vehicle communication in the general vehicle around the training vehicle, so the training vehicle that tends to perform inexperienced driving such as sudden stop and low speed driving that are common to the training vehicle There is an effect that it is possible to provide driving support for ensuring safe traveling with respect to surrounding general vehicles.

  Even if the driver of a general vehicle is unaware that the vehicle ahead is a training vehicle, the distance between vehicles set by the inter-vehicle distance control system changes if the training vehicle is traveling ahead of the host vehicle. Therefore, there is an effect that driving support for ensuring safe traveling can be achieved for a general vehicle behind a training vehicle that tends to perform immature driving such as sudden stop and low-speed traveling.

  In addition, while there is a possibility that the driving route of the learning vehicle and the driving route of the general vehicle around the learning vehicle may cross each other, the learning vehicle is limited to the passenger seat. Since the warning is output, there is an effect that it is possible to provide a driving support device that can provide driving support for ensuring safety during the training not only in the general vehicle around the training vehicle but also in the training vehicle.
