Description

  The present invention relates to a guidance system and a guidance program.

  Conventionally, there has been known a navigation device for guiding a traveling route which is a route on which a vehicle should travel to a set destination (see, for example, Patent Document 1).

JP 2003-57057 A

  By the way, in the navigation apparatus of patent document 1, when the parking lot is set as the destination, although it will guide the traveling route which goes to the parking lot which is the destination, others going to the parking lot of the said destination In some cases, a road where traffic congestion is occurring is guided as a travel route. And as for the cause of occurrence of this traffic congestion, for example, the cause is that the parking lot is already full and can not be parked, or other than the fact that the parking lot is full and can not be parked. There may be various causes such as those caused by factors (for example, a parking lot is an empty car and can be parked but it takes time to enter the parking lot).

  However, on the side of a vehicle traveling on a traffic road, it is difficult to determine the cause of the traffic congestion, so it is not possible to actually judge whether the vehicle can be parked in the parking lot. Despite the lack of space and the inability to park, there was a possibility that in the traffic jam leading to the parking lot it would be necessary to wait for the parking needlessly.

  The present invention has been made in view of the above, and it is possible to prevent wasteful waiting for parking in a traffic jam leading to a parking lot despite the fact that the parking lot is not available and can not be parked. It aims to provide a possible guidance system and guidance program.

  In order to solve the problems described above and to achieve the object, the guidance system according to the present invention determines whether or not a vehicle heading for a parking lot is traveling on a road in a traffic jam leading to the parking lot. And parking determination means for determining whether or not the vehicle can be parked in the parking lot when the congestion determination means determines that the vehicle is traveling on a road in heavy traffic, and the determination result of the parking determination means And guiding means for guiding the parking lot based on the information.

  Further, the guidance program according to the present invention includes a computer, traffic jam determining means for determining whether or not a vehicle heading for a parking lot is traveling on a road where there is traffic to the parking lot, and the traffic jam determining means Parking determination means for determining whether the vehicle can be parked in the parking lot when it is determined that the vehicle is traveling on the road, and guidance about the parking lot based on the determination result of the parking determination means Function as guidance means to perform.

  According to the guidance system according to the present invention, it is possible to determine, for example, whether or not parking can be performed in the parking lot by performing guidance on the parking lot based on the determination result of whether or not parking can be performed in the parking lot. When traveling on a congested road leading to a parking lot, it is possible to prevent the user from waiting to wait in vain in a traffic jam leading to the parking lot despite the fact that the parking lot is not available and can not be parked Is possible.

    According to the guidance program according to the present invention, it is possible to determine, for example, whether or not parking can be performed in the parking lot by performing guidance on the parking lot based on the determination result of whether or not parking can be performed in the parking lot. When traveling on a congested road leading to a parking lot, it is possible to prevent the user from waiting to wait in vain in a traffic jam leading to the parking lot despite the fact that the parking lot is not available and can not be parked Is possible.

As shown in FIG. 2, the parking lot information is configured by mutually associating the item “parking lot ID”, the item “position information, and the item“ free space information ”, and the information corresponding to each item. . Here, the information corresponding to the item "parking lot ID" is parking lot identification information that uniquely identifies a parking lot on the map (hereinafter, "identification information" will be referred to as "ID") (in FIG. 2, "IDp1" which is parking lot ID of parking lot P1 of FIG. 3, "IDp2" which is parking lot ID (not shown) etc.).

(processing)
Next, guidance processing executed by the on-vehicle apparatus 1 configured as described above will be described. FIG. 4 is a flowchart of the guidance process (steps will be abbreviated as “S” in the following description of each process). The guidance process is a process of providing guidance regarding a parking lot. And although the timing which performs this guidance processing is arbitrary, for example, after turning on the power supply of in-vehicle device 1, the destination of the self-vehicle is set by predetermined operation via touch pad 13, and control unit 18 When guidance of a traveling route, which is a route on which the vehicle should travel, is started, it will be described starting from the start as execution is started repeatedly. In addition, when the guidance of this traveling route is started, the control unit 18 causes the image of the front side of the vehicle to be a peripheral image with the fluorocarbon camera of the imaging unit 12 for a predetermined time interval (for example, 0.5 seconds to 1 Description will be made as starting a process (hereinafter, repeated shooting process) of shooting repeatedly in seconds, etc.). Here, for example, by setting the destination of the vehicle in the parking lot P1 of FIG. 3 by a predetermined operation via the touch pad 13, the guiding unit 183 guides the traveling route which is the route the vehicle should travel. An example case will be described.

  In SA1 of FIG. 4, the traffic congestion determination unit 181 determines whether the destination of the vehicle is a parking lot. Specifically, although it is arbitrary, for example, whether the specified destination corresponds to the position of the parking lot with reference to the map information of the map information DB 171 by specifying the destination set at the start of the guidance process It is determined whether or not the destination is a parking lot based on the determination result. Then, if the specified destination does not correspond to the position of the parking lot, it is determined that the destination is not a parking lot (NO in SA1), and the process ends. When the specified destination corresponds to the position of the parking lot, it is determined that the destination is a parking lot (YES in SA1), and the process shifts to SA2. Here, for example, in FIG. 3, when the destination of the vehicle is set to the parking lot P1, it is determined that the destination is the parking lot.

  At SA2 in FIG. 4, the traffic congestion determination unit 181 acquires a surrounding image. Specifically, although it is arbitrary, for example, an image on the front side of the own vehicle taken in the repetitive photographing processing is acquired as a peripheral image for a predetermined time (for example, 3 minutes to 5 minutes) ). Here, for example, in FIG. 3, a plurality of peripheral images in which a parking waiting vehicle on the front side (upper side in the drawing) of the own vehicle is shown are acquired.

  In SA3 of FIG. 4, the traffic congestion determination unit 181 determines whether or not the vehicle heading for the parking lot is traveling on a road in which the parking lot is reached. Specifically, although it is arbitrary, for example, the determination is made based on the peripheral image of the host vehicle and the vehicle speed of the host vehicle.

  Specifically, first, the traffic congestion determination unit 181 acquires the surrounding image acquired in SA2, and determines whether or not the vehicle row appears in a plurality of acquired peripheral images (hereinafter, the vehicle row determination). Specifically, when the number of vehicles ahead of the host vehicle shown in the peripheral image is equal to or greater than a predetermined number (for example, 2 to 5), it is determined that the vehicle row is shown, and When the number of vehicles on the front side is less than a predetermined number, it is determined that the vehicle row is not captured.

  Next, arbitrary image recognition is performed on a plurality of acquired peripheral images, and a temporal change in inter-vehicle distance between the vehicle and the vehicle immediately before appearing in the peripheral image is specified, and the specified inter-vehicle distance is approximately It is determined whether or not it is constant (hereinafter, the inter-vehicle distance determination). Specifically, when the change in the specified inter-vehicle distance is within a predetermined range (for example, 5 m to 10 m), it is determined that the inter-vehicle distance is substantially constant, and the change in the specified inter-vehicle distance is predetermined. If it deviates from the range (e.g., 5 m to 10 m), it is determined that the inter-vehicle distance is not substantially constant.

  Next, the traffic congestion determination unit 181 determines whether the vehicle speed is low (hereinafter, the vehicle speed determination). Specifically, similarly to the conventional case, a control unit (not shown) of the host vehicle receives a signal specifying the number of revolutions of the axle, and measures the vehicle speed of the host vehicle based on the received signal. It is determined as follows that the threshold vehicle speed is stored in the data recording unit 17 in advance. The “threshold vehicle speed” is a threshold for determining traffic congestion, and is compared with, for example, the above-mentioned identified vehicle speed. For example, 30 km / h to 40 km / h are stored. Do. Then, the traffic congestion determination unit 181 acquires the measured vehicle speed and the threshold vehicle speed, and determines that the acquired vehicle speed is low if the acquired vehicle speed is equal to or less than the acquired threshold vehicle speed, and the acquired threshold If it is faster than the vehicle speed, it is determined that the vehicle is not at a low speed.

  Next, based on the determination result of the above-described vehicle row determination, inter-vehicle distance determination, and vehicle speed determination, the traffic congestion determination unit 181 determines whether the host vehicle heading to the parking lot is traveling on a road in congestion that leads to the parking lot. Determine if Specifically, when it is determined that the vehicle array is not captured in the vehicle array determination, when it is determined that the inter-vehicle distance is not substantially constant in the inter-vehicle distance determination, or the vehicle speed is low in the vehicle velocity determination If it is determined that the vehicle is not one, it is determined that the vehicle heading for the parking lot is not traveling on a road in a traffic jam leading to the parking lot (NO in SA3), and the process ends. In addition, when it is determined that the vehicle array is reflected in the vehicle array determination, and it is determined that the inter-vehicle distance is substantially constant in the inter-vehicle distance determination, and determined that the vehicle speed is low in the vehicle velocity determination. Then, it is determined that the vehicle heading for the parking lot is traveling on a road in a traffic jam leading to the parking lot (YES in SA3), and the process shifts to SA4. Here, for example, in FIG. 3, a plurality of vehicles form a train leading to the parking lot P1 and become a traffic jam, and therefore, it is a low speed, and the time change of the inter-vehicle distance is almost constant. In this case, it is determined that the vehicle heading for the parking lot is traveling on a road in a traffic jam leading to the parking lot.

  At SA4 in FIG. 4, the parking determination unit 182 estimates the number of parking waiting vehicles. Specifically, although it is arbitrary, for example, it is estimated based on the current position of the vehicle and the position of the parking lot. Specifically, first, the current position detection unit 16 is accessed to specify the current position of the vehicle by the map information of the map information DB 171, and the guide information is activated with reference to the map information of the map information DB 171. After specifying the position of the parking lot which is the destination set at times, the distance on the traveling route from the current position of the vehicle to the position of the parking lot is calculated. Next, when a train is formed at the time of traffic congestion, the distance between the cars in the train is substantially constant, and the entire length of the vehicle is a constant length (for example, 3.5 m to 4.5 m). Focusing on the fact that there is a vehicle for each predetermined distance interval (for example, 30 m to 40 m, etc. but 30 m will be explained below) in a traffic jam in a traffic jam, the above calculated distance is The number of vehicles waiting for parking is estimated by performing computations using a dividend and a predetermined distance interval as a divisor.

  Here, for example, in FIG. 3, the current position detection unit 16 is accessed to specify the current position of the vehicle with map information in the map information DB 171, and guidance is provided with reference to the map information in the map information DB 171. After the position of the parking lot which is the destination set at the start of the process is specified, 600 m is calculated as the distance on the traveling route from the current position of the vehicle to the position of the parking lot P1. Next, a calculated distance of 600 m is taken as a dividend, and a predetermined distance interval (corresponding to a distance obtained by adding the total length of one vehicle to the distance between vehicles and the vehicle) is taken as a divisor of 30 m. By performing "600 ÷ 30" which is a calculation, 20 units are estimated as the number of vehicles waiting for parking.

  At SA5 in FIG. 4, the parking determination unit 182 determines whether the vehicle can be parked in the parking lot. Specifically, although it is arbitrary, for example, first, the number of parking waiting vehicles estimated in SA4 is acquired, and the parking lot in FIG. 2 is obtained by appropriate communication with the center apparatus 2 via the communication unit 11. The information is accessed, the position information and the free space information are referenced, and the free space information corresponding to the position of the parking lot which is the destination of the vehicle is acquired. Next, the acquired number (that is, the number of parking waiting vehicles estimated in SA4) is compared with the number specified by the acquired vacant amount information, and based on the comparison result, whether the vehicle can be parked in the parking lot Determine Then, when the number of waiting vehicles for parking estimated at SA4 is larger than the number for which the acquired free space information is specified, it is judged that the vehicle can not be parked in the parking lot after judging that there is no space at present. It transfers to SA7 (NO of SA5). In addition, when the number of parking waiting vehicles estimated in SA4 is less than or equal to the number specified by the acquired free space information, it is determined that the vehicle can be parked in the parking lot after judging that there is a space at present. (YES in SA5), shift to SA6.

  Here, for example, first, 20 units are acquired as the number of parking waiting vehicles estimated in SA4, and the parking lot information in FIG. 2 is accessed by appropriate communication with the center apparatus 2 via the communication unit 11 Then, referring to the position information and the free space information, the free space information “30” corresponding to “(x11, y11)” which is the position of the parking lot P1 which is the destination of the vehicle is obtained. . Next, 20 units, which is the acquired number, and 30 units, which is the number for which the acquired free space information is specified, are compared, and "20", which is the estimated number of parking waiting vehicles, Since the number is less than or equal to “30,” which is the number to be specified, it is determined that the vehicle can be parked in the parking lot after judging that there is a vacancy at the present time.

  At SA6 in FIG. 4, the guiding unit 183 gives guidance on the parking lot. Specifically, although it is arbitrary, for example, it is determined that it is possible to park in the parking lot which is the destination set at the time of activation of the guidance processing, the display 14 or the speaker 15 is used to Guidance is provided by outputting information (for example, text information or voice information) indicating that parking is possible. Here, for example, a message such as “Please proceed as it is” is displayed and output, or voice output is given to guide the user to park in the parking lot P1.

  Further, at SA5 in FIG. 4, it is determined that the vehicle can not be parked in the parking lot (NO at SA5), and at SA7 after that, the guiding unit 183 performs guidance on the parking lot. Specifically, although it is arbitrary, for example, it is determined that it is not possible to park in the parking lot which is the destination set at the start of the guidance process, so parking in the parking lot via the display 14 or the speaker 15 The guidance is given by outputting information (for example, text information or voice information) to the effect that it is not possible. In addition, the current position detection unit 16 is accessed to specify the current position of the vehicle by map information in the map information DB 171, and another map near the current position in the map information (that is, when the guidance processing is activated) A guide is given by searching for a parking lot other than the parking lot set in the set destination and outputting information (for example, map information, text information, or voice information) indicating that the user is heading to the searched parking lot . Here, for example, a message such as “the parking lot is full” is displayed or output as voice, and it is informed that the parking lot P1 is full, and also for other parking lots in the vicinity. Display a map showing the position on the display 14, display a message recommending going to the other parking lot, or voice output through the speaker 15 to guide the other parking lot Do. This completes the guidance process.

(Effect of the embodiment)
As described above, according to the present embodiment, for example, whether or not the vehicle can be parked in the parking lot can be obtained by performing guidance on the parking lot based on the determination result of whether the vehicle can be parked in the parking lot If you are traveling on a congested road leading to a parking lot, you will continue to wait in vain for parking in a traffic jam that leads to a parking lot, even though there is no parking space actually available. It becomes possible to prevent that.

  In addition, based on the peripheral image of the vehicle and the vehicle speed of the vehicle, it is determined whether the vehicle is traveling on a road in a traffic jam, for example, the actual state of the vehicle periphery or the actual vehicle speed (that is, real time Since it can be determined reflecting the actual information (which can change), it is possible to improve the determination accuracy as to whether or not the user is traveling on a busy road.

  Also, based on the current position of the vehicle and the position of the parking lot, the number of waiting vehicles for parking between the vehicle and the parking lot is estimated, and the estimated number is compared with the free space of the parking lot. Since it can be determined without actually counting parking waiting vehicles, for example, by determining whether the vehicle can be parked in the parking lot, it is easy to determine whether the vehicle can be parked in the parking lot It is possible to do

(About the surrounding image)
Moreover, although the said embodiment demonstrated the case where the front image of the own vehicle was used as a periphery image, it does not restrict to this. The imaging unit 12 is configured by a camera capable of capturing an image in a direction other than the front of the host vehicle (for example, side, rear, etc.), and using a side image or a rear image, etc. It may be determined whether the vehicle is traveling.

(About estimation of the number of vehicles waiting for parking)
In addition to or instead of the method of SA 4 of FIG. 4 described in the above embodiment, the number of vehicles waiting for parking may be estimated in consideration of the following concept. For example, when it is assumed that the front camera of the imaging unit 12 can capture all the cars ahead, such as when the road leading to the parking lot is curved or the number of vehicles waiting for parking is small, etc. The number of vehicles waiting for parking may be estimated by acquiring an image in front of the vehicle and recognizing the image. In any case such as this case, if the road on which the host vehicle is traveling is a narrow road such as one lane, in addition to the parking waiting vehicle, the vehicle on the front side of the host vehicle waits for parking There is also a possibility that vehicles may also exist with the destination side ahead of the parking lot as a destination, but whether the vehicle ahead is narrowing to the parking lot side, or is it a blinker on the parking lot side The parking waiting vehicle may be identified based on whether or not the parking waiting vehicle is estimated based on the identification result.

(About guidance of parking lot)
Further, in the above embodiment, when it is determined that parking is possible in SA5 of FIG. 4 (YES in SA5), the following processing may be performed instead of SA6. Specifically, the guidance unit 183 takes into consideration, for example, “the distance ÷ the vehicle speed” in consideration of the distance from the current position of the vehicle to the parking lot of the destination and the vehicle speed of the vehicle The time until the vehicle can be parked is calculated by performing the calculation, and if the calculated time is within a predetermined time (for example, a preset time such as 10 minutes to 15 minutes), as in SA6 To guide you to park in the parking lot set as the destination, and to guide you to park in another parking lot in the same way as SA7 if the calculated time exceeds the predetermined time It may be configured.
