The storage unit 6 stores various data used for output control of the start warning, and stores the notification timing determination table 35, the notification level determination table 37, and the map DB 39. The map DB 39 stores map information and is used to specify the location where the vehicle 2 is currently located and the road information around it.

FIG. 3 is a diagram showing a notification timing determination table 35.
The notification timing determination table 35 is data for advancing or delaying the timing (hereinafter referred to as “notification timing”) O for outputting a start warning based on the driver state P and the vehicle state Q. Is.
More specifically, in the present embodiment, the notification timing O is set according to the probability that the driver D is aware that the current situation is in a startable situation in which the start operation for starting the vehicle 2 may be performed. It is variable. That is, when this probability is low, the notification timing O is earlier than usual (“middle” in the figure) (in the figure, “early”), and conversely, when this probability is high, the notification timing O is set. It is supposed to be late ("late" in the figure). The notification timing determination table 35 defines such a relationship between the probability and the notification timing O.

In the present embodiment, the probability that the driver D is aware of the startable situation is determined by the control unit 3 based on the driver state P. As shown in FIG. 3, the driver state P, which is the basis for this determination, includes the operation of the driver D (“device operation” in the figure) P1 for the devices not involved in the driving operation, and the dozing of the driver D. P2 is used.

For example, when the device operation P1 is detected (in the figure, the device operation P1 = "Yes"), the driver D is performing an action that is not related to the start operation, so there is a possibility that the driver D does not recognize the start possible status. expensive. Further, even when the doze P2 of the driver D is detected (in the figure, the doze P2 = “Yes”), it is highly probable that the startability status is not recognized.
On the contrary, when both the device operation P1 and the doze P2 are not detected (in the figure, the device operation P1 = "nothing" and the doze P2 = "nothing"), the driver D can start. Since it can be said that the probability of recognizing is the highest, the notification timing O is set to be later than usual.
On the other hand, when only one of the device operation P1 and the doze P2 is detected (in the figure, only one of the device operation P1 and the doze P2 is "absent"), the driver D Since the probability of recognizing the startable situation is relatively low, the notification timing O is set to be earlier than usual.

Further, in the present embodiment, the notification timing O is set according to the length of time required for the driver D from the start to the completion of the start operation (hereinafter referred to as "start operation required time") in the stopped state of the vehicle 2. It is variable. That is, when the start operation required time is long, the notification timing O is earlier than usual, and conversely, when the start operation required time is short, the notification timing O is delayed. Defines such a relationship between the start operation time required and the notification timing O.

In the present embodiment, the time required for the start operation is determined by the control unit 3 based on the vehicle state Q, and the state of the operation object operated at the time of the start operation is used as the vehicle state Q as the determination material. A parking brake, a shift lever, and a foot brake are used as the operation target.
That is, as shown in FIG. 3, as for the operating state of the parking brake, the state in which the parking brake is operating (hereinafter referred to as "parking on Q1") is acquired. As for the operating state of the shift lever, a state in which the shift lever is located in a position other than neutral and reverse (back) (hereinafter referred to as "shift position Q2") is acquired. Further, as for the operating state of the foot brake, the state in which the foot brake is operating (hereinafter referred to as "foot brake on Q3") is acquired.

Among the operating states of the parking brake, the shift lever, and the foot brake, the state in which the starting operation time is the shortest is the operating state in which the number of operations required for the starting operation is the smallest. In such an operating state, as shown in FIG. 3, the parking brake is not operating (parking brake on Q1 = "N"), and the shift lever is located in a position other than neutral and backward (shift position Q2 = "Y"). "), And the foot brake is operating (foot brake on Q3 =" Y "). Regarding this operation state, the notification timing O is delayed because the time required for the start operation is short.

The combination of the driver state P, the vehicle state Q, and the notification timing O shown in FIG. 3 is merely an example, and can be appropriately changed based on various conditions and other factors.

FIG. 4 is a diagram showing a notification level determination table 37.
The notification level determination table 37 is setting data for varying the intensity level of the stimulus given to the driver D by the start warning output (hereinafter referred to as the notification level U) based on the situation at that time. In the present embodiment, the greater the influence that the state in which the start operation of the own vehicle is not performed (that is, the stop or the start delay of the own vehicle) has on the surroundings (particularly other vehicles such as the rear vehicle T2), the more the notification level U is normally (that is). Higher than "Medium" in the figure) ("High" in the figure), and conversely, the smaller this effect, the lower the notification level U than normal ("Medium" in the figure) (in the figure, "Medium"). "Low"). Further, when this influence is not abbreviated, the output of the start warning itself is unnecessary (notification level U = "unnecessary"). The notification level determination table 37 defines such a relationship between this effect and the notification level U.

In the present embodiment, the influence of the state in which the start operation of the own vehicle is not performed on the other vehicle is determined by the control unit 3 based on the peripheral information collected by the own vehicle peripheral information collecting unit 8. As peripheral information T for determining the influence, the current lane information of the own vehicle, the presence / absence of the rear vehicle T2, the presence / absence of the traffic signal immediately before the own vehicle, the presence / absence of the front vehicle T5, and the congestion information of the road R are used. ing.

For example, when the own vehicle is not located in the lane of the road R (“T1 on the road” = “N” in FIG. 4), even if the own vehicle continues to stop, there is almost no effect on other vehicles.
On the other hand, when the own vehicle is located in the lane of the road R (“T1 on the road” = “Y”), when the rear vehicle T2 is present, the stop of the own vehicle affects the rear vehicle T2. There is a probability. In this case, especially when the road R is congested (“congested T3” = “Y”) and when the own vehicle is located in front of the traffic signal (“T4 before the signal” = “Y”). If the vehicle does not start promptly in accordance with the change of the traffic signal, it will be a factor of prolonging the traffic jam and will have a great influence on the rear vehicle T2. Therefore, at this time, the notification level U is set to the highest level.

On the other hand, if the own vehicle is not T3 in front of the traffic light ("T4 in front of the traffic light" = "N") and there is no vehicle T5 in front ("T5" in front of the traffic light = "N"), there is some reason other than the traffic rule. It is highly probable that the driver D is intentionally stopped due to (for example, a stop on the shoulder of a road or a vehicle trouble). Therefore, in this case, since it is presumed that the other vehicle travels while avoiding the own vehicle, it is determined that there is almost no influence, and the notification level U is set to "unnecessary".

The combination of the peripheral information T and the notification level U in FIG. 4 is merely an example, and may be appropriately changed based on various conditions and other factors.

FIG. 5 is a diagram showing an example of the notification level U.
As shown in the figure, the difference in the intensity of the notification level U is realized by three combinations of the vibration intensity of the seat of the driver D, the mode of voice output, and the mode of display output.
For example, the vibration intensity of the sheet becomes stronger as the notification level U becomes higher.
Further, the start warning voice (“guidance voice” in the figure) is output only when the notification level U is “high”, and at this time, it is output together with the notification alarm sound.
When the notification level U is "low", the start warning is displayed in a simple manner (for example, an icon or a comment) on a part of the display ("simple notification display" in the figure). When the notification level U is "medium" or "high", a start warning is displayed in full screen on the display ("display full notification display" in the figure).
When the notification level U is "unnecessary", none of the sheet vibration, voice output, and display output is performed.

FIG. 6 is a flowchart showing the notification process of the notification device 1.
When the control unit 3 determines that the own vehicle is stopped (step S1: YES) based on the detection result of the vehicle state acquisition unit 9, the control unit 3 detects a start possible situation in which the own vehicle 2 may start.
That is, the control unit 3 determines the presence / absence of the vehicle in front T5 based on the information collected by the information collection unit 8 around the own vehicle (step S2). When there is a vehicle T5 in front (step S2: YES), when the vehicle T5 in front starts (step S3: YES), it means that the vehicle can start.
On the other hand, when there is no vehicle T5 in front (step S2: NO), the control unit 3 determines that the vehicle owns a traffic signal signal (“red light” in Japan) based on the information gathering unit 8 around the own vehicle. It is determined whether or not the vehicle is stopped by (lighting) (step S4). When the own vehicle is stopped by the traffic signal (step S4: YES), when the signal of the traffic signal changes to something other than "stop"("greenlight" in Japan) (step S5: YES), It means that it is possible to start.

If there is no vehicle T5 in front (step S3: NO) and the own vehicle has not stopped due to the signal of the traffic signal (step S4: NO), the own vehicle has temporarily stopped while moving. Instead, it is presumed that the vehicle is stopped for some reason such as parking. Under such a situation, it is not necessary to output a start warning to the driver D, so that the control unit 3 ends the process.

When the start possible situation is reached while the own vehicle is stopped, a start warning is output in principle, but in order to control the output of this start warning (that is, presence / absence of notification, notification timing O, and notification level U). , The control unit 3 executes the following processing.

That is, the control unit 3 detects the driver state P and the vehicle state Q based on the information of the vehicle information collection unit 7 (step S6), and the notification timing according to the driver state P and the vehicle state Q. O is set based on the notification timing determination table 35 (step S7). Further, the control unit 3 acquires the peripheral information T from the own vehicle peripheral information collecting unit 8 (step S8), and sets the notification level U according to the peripheral information T based on the notification level determination table 37. (Step S9).

Here, in the present embodiment, when the own vehicle 2 turns left or right after starting, the starting warning is changed according to the surrounding situation at that time.
That is, when the winker is operated (step S10: YES, the control unit 3 is instructed by the winker in the traveling direction (right turn direction or left turn direction) based on the information of the own vehicle peripheral information collecting unit 8). ) Is determined whether or not there is an event that can inhibit the progress after starting (hereinafter referred to as “progress inhibition event”) (step S11). Examples of this event include the presence or absence of a pedestrian or another vehicle in the direction of travel. , The presence of an oncoming vehicle when turning right while driving in the left lane.
When there is a progress-inhibiting event (step S11: YES), the control unit 3 changes the start warning to a notification in which "a content that calls attention to the progress-inhibiting event" is added to "a notification content that prompts the start". (Step S12).

Next, the control unit 3 starts timing the elapsed time in order to output a start warning at the notification timing O set in step S7 (step S13).
During this timing, the control unit 3 detects the presence or absence of the start operation of the driver D (step S14), and if the driver D performs the start operation before reaching the notification timing O (step S14: YES). Since it is not necessary to notify the driver D of the start warning, the control unit 3 does not output the start warning, and the notification process ends in step S15).

On the other hand, if it is determined that the start operation has not been performed before S elapses until the notification timing O is reached without the start operation of the driver D being detected (step S14: NO), control is performed. The unit 3 causes the notification unit 4 to output a start warning at the set notification level U (step S16). The control unit 3 continues the start warning until the start operation of the driver D is detected (step S17: NO), and when the start operation is detected (step S17: YES), the control unit 3 is notified by the notification unit 4. The start warning from is stopped (step S18), and the notification process is terminated.

Next, a specific example of the start warning output by the above notification process will be described.

FIG. 7 is an explanatory diagram of the first specific example.
In this specific example, the vehicle 2 itself is located in the lane R1 of the road R, the front vehicle T5 and the rear vehicle T2 are in this lane R1, and the front vehicle T5 is stopped. Is.
In this case, when the vehicle T5 in front starts traveling (FIG. 6, step S3: YES), in steps S6 to S9 of the above notification process, the driver state P, the notification timing O corresponding to the vehicle state Q, and the periphery The notification level U according to the information T is set.

For example, as shown in FIG. 8A, when the driver D directs the line-of-sight direction F to the audio device 70 and operates the audio device 70, "Yes" of the device operation P1 is detected as the driver state P. To. In this case, it takes time for the driver D to recognize the startability status (starting of the front vehicle T5), and there is a high possibility that the driver D will hinder the running of other vehicles such as the rear vehicle T2. In addition, if the start of the own vehicle is delayed, there is a possibility that the rear vehicle T2 will alert the driver with a horn or the like. Therefore, in this case, as defined in the notification timing determination table 35 of FIG. 3 above, the notification timing O of the start warning is earlier than usual.

Further, for example, as shown in FIG. 8B, when the driver D faces the line-of-sight direction F firmly forward, the driver state P is "nothing" in the device operation P1 and "nothing" in the doze P2. Is detected. In this case, it is highly probable that the driver D is aware of the start possible status (start of the vehicle T5 in front) and does not need the start warning of the notification device 1. Therefore, in this case, as defined in the notification timing determination table 35 of FIG. 3 above, the notification timing O of the start warning is delayed more than usual. After that, if the driver D starts the vehicle before the notification timing O arrives, the start warning output is canceled and is not output by the processing of steps S14 and S15 of the notification processing.

As a result, the driver D recognizes the start possible situation, and the start warning is not output even though the start operation is actually performed, and the annoyance for the start warning is reduced. Further, the higher the probability that the driver D is aware of the start possible situation, the later the notification timing O is delayed. Therefore, the number of cases where the start operation is performed before the notification timing O increases, and the start warning is actually output. The case is also suppressed, and the troublesomeness is further reduced. Even if it is highly probable that the driver D is aware of the start possible situation, if the start operation is not actually performed by the notification timing O, a start warning is output and the driver D starts. Can be encouraged.

FIG. 9 is an explanatory diagram of the second specific example.
In this specific example, the vehicle 2 itself is located in the lane R1 of the road R, is stopped by the signal of the traffic signal V in front of the traffic signal V, and there is a rear vehicle T2. ..
In this case, when the signal of the traffic signal V changes (FIG. 6, step S5: YES), the driver state P and the vehicle state Q are set in steps S6 to S9 of the above notification processing as in the first specific example. The corresponding notification timing O and the notification level U according to the peripheral information T are set.
In this specific example, since the own vehicle peripheral information collecting unit 8 also collects the signal change of the traffic signal V as the peripheral information, the starting possible situation (traffic signal V signal) even when the preceding vehicle T5 does not exist. The change) can be promptly detected, and a start warning can be output at the notification timing O according to the driver state P and the vehicle state Q and the notification level U according to the peripheral information T.

FIG. 10 is an explanatory diagram of the third specific example.
In this specific example, the vehicle 2 itself is located in the lane R1 of the road R, is stopped by the signal of the traffic signal V in front of the traffic signal V, and the vehicle 2 is turned right from the operating state of the winker 71. Is predicted.
In this case, when the signal of the traffic signal V changes (FIG. 6, step S5: YES), the driver state P and the driver state P and in steps S6 to S9 of the above notification process are the same as in the first and second specific examples. The notification timing O according to the vehicle state Q and the notification level U according to the peripheral information T are set.
Further, in this specific example, when there is an event (progress inhibition event) that can hinder the progress of the vehicle 2 in the right turn direction in the above notification processing steps S10 to S12, the "progress" is added to the "progress". The start warning is changed to the notification of the content with "content that calls attention to the obstructive event". In this specific example, since the oncoming vehicle 2A traveling in the lane R2 where the own vehicle 2 is scheduled to cross is approaching, the notification for recognizing the existence of the oncoming vehicle 2A is "Caution for the progress obstruction event". Is added to the start warning as "contents that urge".
This prevents the driver D from reacting to the "prompt to start" by the start warning and starting the vehicle 2 in a state where the surroundings are not sufficiently confirmed in the situation where the progress inhibition event is occurring. Will be done.

As described above, according to the present embodiment, the following effects are obtained.

In the notification device 1 of the present embodiment, since the control unit 3 controls the output of the start warning according to the driver state P, the state of the driver D is reduced so as to reduce the annoyance felt by the driver D in the start warning.
