  Here, in the above parking / stopping determination device, for example, because the width of the roadway is narrow, it is difficult for other vehicles to pass around the parked vehicle on the roadway (hereinafter simply referred to as “parking / stopping vehicle vicinity”). However, if the parking position is not in the parking prohibited area, the driver is not notified that parking cannot be performed. Therefore, in the vehicle parking / stopping determination device, smooth traffic may be hindered.

  On the other hand, in order to ensure smooth traffic when the vehicle is parked or stopped, the driver is not allowed to park or park when the traffic width around the parked vehicle is equal to or less than a specified value (for example, the maximum possible vehicle width). It is conceivable that the notification is performed. However, in this case, depending on the size of the specified value, even if other vehicles that are about to pass around the parked vehicle can pass around the parked vehicle, the driver is notified that parking is not possible. There is a risk that.

  Then, this invention makes it a subject to provide the parking stop determination apparatus which can ensure smooth traffic and can perform notification of the parking stop impossible appropriately.

  In order to achieve the above object, a parking / stopping determination device according to the present invention is a parking / stopping determination device for determining whether a vehicle can park or stop, and a traffic width for acquiring traffic width information around a parked vehicle on a roadway. Based on the acquisition means, the vehicle width acquisition means for acquiring the vehicle width information of other vehicles that may pass around the parked and stopped vehicles, and the traffic width information and the vehicle width information, it is impossible to pass around the parked and stopped vehicles. When it is determined that there is another vehicle that cannot pass around the parked and stopped vehicle, and a determination unit that determines whether or not the other vehicle exists, the driver of the parked and stopped vehicle is notified that the parking and stopping is impossible. And an informing means. “Traffic width” means the width of an area where other vehicles pass while avoiding parked and stopped vehicles.

  According to this parking / stopping determination device, the traffic width information is acquired by the traffic width acquisition means, the vehicle width information of the other vehicle is acquired by the vehicle width acquisition means, and based on the traffic width information and the vehicle width information The determination means determines whether there is another vehicle that cannot pass around the parked and stopped vehicle. As a result, when it is difficult for other vehicles to pass around the parked and stopped vehicle, the driver is notified that the parking and stopping is impossible, and thus smooth traffic can be ensured. Furthermore, as described above, the vehicle width information of other vehicles that may pass around the parked and stopped vehicles is acquired, so depending on the width of the other vehicles that are going to pass around the parked and stopped vehicles. Whether to park or stop is determined. Therefore, it is possible to perform notification in accordance with the actual traffic situation, and appropriately notify the driver that parking / stopping is not possible.

  In addition, the determination means determines whether or not other vehicles that cannot pass around the parked and stopped vehicle pass through the parked and stopped vehicle within a predetermined time, and the notifying means cannot pass around the parked and stopped vehicle. When it is determined that the vehicle does not pass around the parked vehicle within a predetermined time, it is preferable to notify that the vehicle can park and park only within the predetermined time. In this case, it is possible to determine whether or not parking is possible within a predetermined time.

  Moreover, it is preferable that a vehicle width acquisition means acquires the vehicle width information of the other vehicle which may pass around the parking / stopping vehicle within the parking / parking scheduled time designated in advance by the driver. In this case, it is possible to determine whether parking or stopping is possible only within the scheduled parking time.

  According to the present invention, it is possible to ensure smooth traffic and appropriately perform notification that parking and stopping is not possible.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements will be denoted by the same reference numerals, and redundant description will be omitted.

  FIG. 1 is a schematic configuration diagram showing a parking and stopping determination device according to an embodiment of the present invention. The parking / stopping determination device according to the present embodiment is mounted on a vehicle such as an automobile, and is a device that determines whether the vehicle can park or stop. As shown in FIG. 1, the parking / stop determination device 1 includes a parking / stop recognition unit 2, a roadway information acquisition unit 3, a vehicle width information acquisition unit 4, a controller 5, and a notification device 6. “Parking / stopping” means parking and stopping.

  The parking / recognition unit 2 is for recognizing the parking / stopping of the host vehicle. Here, for example, a vehicle speed sensor that detects the vehicle speed of the host vehicle and a shift sensor that detects a shift position are used as the parking / stopping vehicle recognition unit 2. This parking / stopping recognition unit 2 outputs the detected vehicle speed and shift position to the controller 5.

  The roadway information acquisition unit 3 acquires roadway information relating to a certain range of roadway conditions including parked and stopped vehicles (the own vehicle parked and stopped). Specifically, map information around the parked vehicle, position / range information of the obstacle, etc. are acquired. More specifically, for example, the width of the roadway, the number of lanes, the position of the intersection, the vehicle width of the parked vehicle, the width of the parked vehicle that protrudes from the roadway, other parked vehicles around the parked vehicle Information such as the position / range of the vehicle (other vehicles parked / stopped), the position / range of the construction site around the parked / stopped vehicle, etc. is acquired.

  Here, as the roadway information acquisition unit 3, for example, a transceiver such as an inter-vehicle communication system or an inter-vehicle communication system (including a road traffic information communication system (VICS)), an autonomous radar, or a combination thereof is used. It has been. The roadway information acquisition unit 3 outputs the acquired roadway information to the controller 5. Note that, as the road information acquisition unit 3, a car navigation terminal or the like may be used, and the road information may be acquired using information input in advance in the car navigation terminal or the like.

  The vehicle width information acquisition unit 4 acquires vehicle width information relating to the vehicle width of other vehicles that may pass around the parked and stopped vehicle (hereinafter simply referred to as “parked and parked vehicle periphery”) on the roadway. Here, as the vehicle width information acquisition unit 4, for example, a GPS (Global Positioning System), and a transceiver of an inter-vehicle communication system such as an inter-vehicle communication system and an inter-vehicle communication system (including those using a center). Is used.

  In this vehicle width information acquisition unit 4, as a method of determining whether or not there is a possibility that another vehicle will pass around the parked and stopped vehicle, another vehicle existing within a certain range around the parked and stopped vehicle is obtained by GPS. Then, the obtained vehicle width information in the other vehicle is acquired by inter-vehicle communication and output to the controller 5.

  The vehicle width information acquisition unit 4 may acquire the turn-on state of the turn signal of the other vehicle, and based on this, may determine whether or not the other vehicle may pass around the parked and stopped vehicle. In addition, for example, other vehicles traveling in the right-turn exclusive lane do not travel in the straight direction, so the travel route of the other vehicle is predicted by obtaining the lane position where the other vehicle travels, and thereby the other vehicle is parked. It may be determined whether there is a possibility of passing around a stopped vehicle.

  Alternatively, as the vehicle width information acquisition unit 4, the car navigation system of each other vehicle is used, and whether or not there is a possibility that the other vehicle passes around the parked and stopped vehicle from the route set in these car navigation systems. It may be judged. Alternatively, the vehicle width information acquisition unit 4 uses intention estimation means for estimating the driver's intention, and other vehicles can pass around the parked and stopped vehicles by detecting the driver's eyes and the like with a camera, for example. In some cases, it is determined whether or not there is sex.

  The controller 5 is composed of, for example, a CPU, a ROM, a RAM, and the like, and executes the following operations by executing software held in the ROM by the CPU. That is, the controller 5 recognizes the parking / stopping of the host vehicle based on the vehicle speed and the shift position input from the parking / stopping recognition unit 2. Based on the roadway information input from the roadway information acquisition unit 3, the traffic width around the parked and stopped vehicle is obtained. Then, based on the obtained traffic width and the vehicle width input from the vehicle width information acquisition unit 4, it is determined whether or not there is another vehicle that cannot pass around the parked and stopped vehicle (details will be described later). .

  The notification device 6 notifies the driver of the determination result determined by the controller 5. The alarm device 6 has an in-vehicle terminal 6a provided in the vehicle and a portable terminal 6b using, for example, a DMC (Data Communication Module). The in-car terminal 6a displays characters / marks or the like on the display unit to notify that parking is possible or not. For example, a display unit such as a car navigation terminal or a meter is used as the display unit. Further, the in-vehicle terminal 6a outputs a voice / buzzer or the like from the output unit to notify that parking / stopping is possible or not. For example, a mobile phone or the like is used as the mobile terminal 6b.

  Next, with reference to FIGS. 2 and 3, the operation of the parking / stopping determination device 1 will be described while clarifying the details of the processing procedure of the controller 5.

  First, when the vehicle speed input from the parking / recognition recognition unit 2 is 0 and the shift position is in the P range, it is recognized that the host vehicle is parked / stopped, and using these input vehicle speed and shift position as a trigger, Determination of availability is started (S1).

  Subsequently, roadway information is acquired by the roadway information acquisition unit 3 and vehicle width information is acquired by the vehicle width information acquisition unit 4 (S2). These are input to the controller 5, and the controller 5 Processing is executed.

  First, based on the input roadway information, it is determined whether or not the parking / stopping position is a parking / parking-capable position such as a parking-stoppable area (S3). When it is determined that the parking / stopping position is a parking / stoppable position, the traffic width around the parking / stopping vehicle on the roadway is derived and determined based on the roadway information input from the roadway information acquisition unit 3 (S4).

  FIG. 4 is a diagram illustrating an example of a traffic width around a parked vehicle on a roadway. As shown in FIG. 4A, when the parked and stopped vehicle 10 is parked in parallel on one side in the width direction of the roadway 11, when there is no obstacle around the parked and stopped vehicle, the other end in the width direction of the roadway 11 and The distance from the parked vehicle 10 is determined as the traffic width X. On the other hand, as shown in FIG. 4B, when there is an obstacle (here, another parked vehicle 12) around the parked vehicle, the other end in the width direction of the roadway 11 and the parked vehicle 10 The smaller one of the distance X1 between the two and the distance X2 between the other parked vehicle 12 and the parked vehicle 10 is obtained as the traffic width X.

  Subsequently, based on the obtained traffic width X and the vehicle width information input from the vehicle width information acquisition unit 4, is it possible for other vehicles that want to pass around the parked vehicle to pass around the parked vehicle? It is determined whether or not (S5). When the traffic width X is larger than the maximum vehicle width among the vehicle widths, it is determined that there is no other vehicle that cannot pass around the parked and stopped vehicle, and the alarm 6 informs the driver that the vehicle can park. Is performed (S6), and the determination of whether or not parking is possible is terminated.

  When the traffic width X is equal to or smaller than the maximum vehicle width of the vehicle width, it is determined that there is another vehicle that cannot pass around the parked and stopped vehicle, and the driver notifies the driver that the vehicle cannot park. (S21). Subsequently, another parking / stoppable position is searched based on the roadway information, and the other parking / stoppable position is guided by the alarm device 6 (S22). When the vehicle is parked on the spot, a warning and notification (notification) are given to the driver by the alarm device 6 (S23 → S14).

In addition, in determining whether other vehicles can pass around parked and stopped vehicles, in addition to the above-described determination, for example, a conditional expression as shown in the following expression may be used.
Traffic width X ≧ predetermined value (for example, 2 m)

  On the other hand, if it is determined in S3 that the parking / stopping position is not a parking / stoppable position, it is determined whether or not the parking / stopping position is a stoppable position (S11). Specifically, based on the traffic width X and the vehicle width information, it is determined whether or not another vehicle that cannot pass around the parked and stopped vehicle passes around the parked and stopped vehicle within a predetermined time.

  If it is determined that other vehicles that cannot pass around the parked vehicle do not pass around the parked vehicle within the specified time, the vehicle can park and stop only within the specified time (that is, the vehicle can stop within the specified time) Is notified to the driver by the alarm device 6 (S12). And when predetermined time passes after parking and stopping, a warning and a report (notification) to that effect are given to a driver by portable terminal 6b of alarm 6 (S13-> S14). On the other hand, when it is determined that another vehicle that cannot pass around the parked and stopped vehicle passes through the parked and stopped vehicle within a predetermined time, processing similar to S21 to 23 is executed.

  The roadway information acquisition unit 3 and the controller 5 for deriving the traffic width constitute a traffic width acquisition unit. The vehicle width information acquisition unit 4 constitutes vehicle width acquisition means. The controller 5 that determines whether or not there is another vehicle that cannot pass around the parked and stopped vehicle constitutes a determination unit. The notification device 6 constitutes notification means.

  As described above, according to the parking and stopping determination device 1 of the present embodiment, the vehicle width information is acquired by the vehicle width information acquisition unit 4, the roadway information is acquired by the roadway information acquisition unit 3, and based on the roadway information by the controller 5. A traffic width X around the parked vehicle is required. Then, based on the traffic width X and the vehicle width, the controller 5 determines whether there is another vehicle that cannot pass around the parked and stopped vehicle. Thereby, for example, when it is difficult for another vehicle to pass around the parked vehicle (when the traffic width X ≦ the vehicle width), the driver is notified by the alarm device 6 that the vehicle cannot park. Therefore, it is possible to ensure smooth traffic.

  Furthermore, as described above, since the vehicle width information of other vehicles that may pass around the parked and stopped vehicles is acquired, depending on the width of the other vehicles that are going to pass around the parked and stopped vehicles. Whether to park or stop is determined. Therefore, it is possible to perform notification according to actual traffic conditions, and it is possible to appropriately perform notification with high accuracy that parking and stopping is not possible. As a result, when only other vehicles having a narrow vehicle width pass around the parked and stopped vehicle, the number of parkable and parked areas increases, and it is possible to suppress notification that lacks rationality.

  Further, in the present embodiment, as described above, the controller 5 determines whether or not other vehicles that cannot pass around the parked and stopped vehicles pass around the parked and stopped vehicles within a predetermined time. A notification that the vehicle can be parked is provided by the alarm device 6. Therefore, it is possible to determine whether or not parking is possible within a predetermined time, and it is possible to more appropriately notify that parking is not possible.

  Incidentally, in the vehicle width information acquisition unit 4, as described above, as a method for determining whether there is a possibility that another vehicle may pass around the parked / stopped vehicle, the vehicle width information acquisition unit 4 is not limited to a certain range around the parked / stopped vehicle Since a vehicle is required, the time for guaranteeing such a possibility is generally within a certain time. Therefore, as described above, the above-described effect of performing appropriate notification becomes significant by determining whether parking / stopping is possible within a predetermined time.

  The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments.

  For example, although a shift sensor is used as the parking / recognition recognition unit 2 in the above-described embodiment, the parking / stopping may be recognized by using a vehicle power supply sensor and detecting the vehicle power supply OFF by the controller 5. Moreover, you may recognize implementation of parking and stopping by detecting the opening of a door using a door sensor. Moreover, you may recognize implementation of parking and stopping based on whether a setting destination and the present position correspond in a car navigation terminal. Further, the driver may recognize that the vehicle has been parked or stopped by performing an operation (for example, inputting a parking / parking vehicle availability determination start).

  Moreover, in the said embodiment, although the alarm device 6 has in-vehicle terminal 6a and portable terminal 6b, any one may be sufficient and in-vehicle terminal 6a displays a character / mark etc. on a display part. At the same time, voice / buzzer or the like is output from the output unit, but any one of these functions may be provided.

  Further, in the vehicle width information acquisition unit 4 of the above-described embodiment, the driver inputs the scheduled parking time in advance (specifies in advance), and other vehicles that may pass around the parked vehicle within the scheduled parking / parking time. Vehicle width information may be acquired. In this case, it is possible to determine whether or not parking is possible within the scheduled parking time, and it is possible to more appropriately notify that parking is not possible. Further, in this case, when the scheduled parking / stopping time elapses after the parking / stopping, or when approaching the elapsed time, a notification to that effect may be given by the portable terminal.
