The information presentation function of the vehicle-mounted control device 140 receives the parking lot information transmitted from the information providing device 200 via the vehicle-mounted communication device 130, and presents the received parking lot information to the driver via the presentation device 150. .. The details of the parking lot information and the details of the method of presenting the parking lot information will be described later.

Next, the information providing device 200 according to the present embodiment will be described. The information providing device 200 is a server installed outside the vehicle, and has a server communication device 210, a server processing device 220, and a database 230, as shown in FIG.

The server communication device 210 can communicate with the vehicle-mounted communication device 130 of the vehicle-mounted device 100 by means of a telephone line network or the like. The server communication device 210 receives a plurality of probe information from the plurality of vehicle-mounted devices 100 mounted on the plurality of vehicles, outputs the received plurality of probe information to the server processing device 220, and acquires the received probe information from the server processing device 220. The information is transmitted to the in-vehicle device 100.

The database 230 stores a plurality of probe information acquired from a plurality of vehicles. Such probe information includes the position of the vehicle when the probe information is acquired, the date and time, the outside air temperature, the raindrop detection result, the vehicle type, the position of the shift position, the accelerator opening, the brake opening, the steering angle, and 3.

The server processing device 220 has a probe information analysis function that identifies the parking required time required for the vehicle to park for each parking lot by executing a program stored in the ROM by the CPU, and parking lot information including the required parking time. It is provided with an information providing function for providing the in-vehicle device 100. Each function of the server processing apparatus 220 will be described below.

The probe information analysis function of the server processing device 220 is a parking behavior from the start of parking of the vehicle to the completion of parking based on the probe information collected from the plurality of in-vehicle devices 100 mounted on the plurality of vehicles. Calculate the required parking time for each parking lot. For example, the probe information analysis function obtains probe information when a vehicle exists in or around a parking lot from among a plurality of probe information stored in the database 230 based on the vehicle position information included in the probe information. , Extract as target probe information.

Then, the probe information analysis function calculates, for example, the time t1 when the vehicle enters the parking lot as the parking start time of the vehicle in the parking lot, based on the position information of the vehicle included in the target probe information. In addition, the probe information analysis function sets the time t2 when the vehicle turns off the ignition in the parking lot based on the ignition state of the vehicle included in the target probe information obtained continuously in time. It is calculated as the parking completion time of the vehicle in. Then, the probe information analysis function calculates the time from the parking start time t1 to the parking completion time t2 as the actual required time required for the vehicle to perform the parking action in the parking lot.

Further, the probe information analysis function calculates the actual time required for parking in each parking lot for each vehicle and each date and time based on a plurality of target probe information acquired from a plurality of vehicles. Furthermore, the probe information analysis function calculates a plurality of calculated index values of actual required time (for example, average value, median value, or mode value) for each parking lot, and parks the calculated index value of actual required time. Obtain as the required time. Then, the probe information analysis function stores information on the required parking time in each parking lot in the database 230. In addition, the probe information analysis function can update the parking required time information stored in the database 230 by calculating the parking required time at each parking lot based on the latest target probe information for each predetermined period. it can.

In addition, the probe information analysis function does not set the time when the vehicle enters the parking lot as the parking start time of the vehicle, but sets the time when the vehicle starts waiting for parking outside the parking lot as the parking start time of the vehicle. You can also. Specifically, the probe information analysis function waits for the vehicle to park at the time when the vehicle starts to stop or slow down after it reaches the vicinity of the parking lot (after it is within a predetermined distance from the parking lot). It can be obtained as the starting parking start time. As a result, the actual time required for the vehicle to park the vehicle can be more accurately grasped as the required parking time.

The probe information analysis function is based on shift position information, accelerator opening information, brake opening information, vehicle speed information, camera image information, hazard lamp lighting status information, etc. included in the probe information. It is possible to determine whether the vehicle is stopped or slowing down. For example, the probe information analysis function is used when the shift position is the parking position, the accelerator opening is less than or equal to the predetermined value, the brake opening is greater than or equal to the predetermined value, or the image captured by the camera does not change by more than the predetermined value. , It can be determined that the vehicle is stopped or slowing down when the hazard lamp is lit. In addition, the probe information analysis function can determine that the vehicle is stopped when the vehicle speed is zero, and when the vehicle speed is less than a predetermined speed (for example, 10 km or less), the vehicle slows down. It can be judged that there is.

Furthermore, the probe information analysis function does not set the timing when the vehicle is turned off as the parking completion time of the vehicle, but for example, the time when the door is opened and closed after the ignition is turned off, or the key lock after the door is opened and closed. The time can be set as the parking completion time. Further, the probe information analysis function may set the time when the vehicle window is closed and the time when the wiper switch is turned off as the parking completion time. As a result, the time required for the vehicle to park the vehicle can be more accurately grasped as the required parking time.

Furthermore, the probe information analysis function determines the parking required time included in the parking lot information, the time required for the target vehicle to enter the parking lot after starting parking, and the parking completion after the target vehicle enters the parking lot. It can also be calculated separately from the time required for the operation.

In addition, the probe information analysis function also acquires the attribute information of the parking lot. For example, the probe information analysis function allows the parking lot to be "flat" based on the accelerator opening, brake opening, steering angle, acceleration / deceleration in the three axial directions, and air pressure included in the probe information. It is possible to determine whether the parking lot is a "multi-story parking lot", whether there is a barrier at the entrance or exit of the parking lot, whether the parking lot is a tread type, etc., and obtain the determination result as attribute information. For example, the probe information analysis function is based on the accelerator opening, brake opening, steering angle, acceleration / deceleration in three axial directions, etc., from when the vehicle enters the parking lot to when the vehicle parks. It can be judged that the parking lot is a flat parking lot if it passes through almost the same passage from the time to the advancement, while it is judged as a multi-story parking lot if it can be judged that the parking lot is going around the slope. can do. In addition, the probe information analysis function can also determine whether or not the parking lot is a tread-type parking lot based on the accelerator opening when the vehicle is stopped and the acceleration in the vertical direction.

In addition, the probe information analysis function is based on the position information, steering angle, steering operation amount, front window opening / closing operation, door opening / closing operation, etc. included in the probe information, and the number of times the vehicle is turned back during parking and forward / backward movement. The number of repetitions, the number of times the front window is opened and closed, and the number of times the door is opened and closed (number of times) are specified. From the distribution of opening and closing times (number of times), the parking difficulty level of the parking lot can be determined as attribute information.

The probe information analysis function specifies the number of times the vehicle turns back, the number of times the vehicle moves forward and backward repeatedly, the number of times the front window opens and closes, and the time (number of times) the door opens and closes for each vehicle. When the number of repetitions of forward / backward movement, the number of times of opening / closing the front window, or the number of times of opening / closing the door (number of times) is large, the parking difficulty level of the parking lot can be determined by excluding the history of such a driver. In addition, the probe information analysis function specifies the number of times the vehicle turns back, the number of times the vehicle moves forward and backward, the number of times the front window opens and closes, and the number of times the door opens and closes (number of times) for each vehicle size (vehicle type). It can be configured to determine whether the number of turns, the number of repetitions of forward / backward movement, the number of times of opening / closing the front window, and the opening / closing time (number of times) of the door are due to the size of the vehicle. Then, when the size of the target vehicle is relatively small, the parking difficulty level of the parking lot can be determined based on the probe information of the small vehicle, while when the size of the target vehicle is relatively large. Can also be configured to determine the parking difficulty of a parking lot based on the probe information of a large vehicle.

The information providing function of the server processing device 220 provides the in-vehicle device 100 with parking information including the required parking time and the attribute information of the parking lot. Specifically, the information providing function is the parking required time of the target vehicle or the parking lot existing around the destination of the target vehicle when the target vehicle equipped with the in-vehicle device 100 requests the parking lot information. The parking lot information including the information and the attribute information is acquired from the database 230 and transmitted to the in-vehicle device 100 of the target vehicle. As a result, the in-vehicle device 100 of the target vehicle can present the parking lot information including the parking required time and the attribute information of the parking lot around the target vehicle or the destination to the driver.

In step S202, the probe information analysis function determines whether or not a certain period of time has elapsed since the start of accumulating probe information. The accumulation of probe information in step S201 is repeated until a certain period of time elapses, and when a certain period of time elapses, the process proceeds to step S203.

In step S203, the target probe information is extracted by the probe information analysis function. Specifically, in the probe information analysis function, the vehicle is determined from the parking lot and its surroundings (predetermined from the parking lot) from among the plurality of probe information stored in the database 230 based on the vehicle position information included in the probe information. The probe information obtained when it exists within the range of the distance) is extracted as the target probe information.

In step S204, the probe information analysis function calculates the actual time required for each vehicle to park based on the plurality of target probe information extracted in step S203. For example, the probe information analysis function first calculates the time when the vehicle enters the parking lot as the parking start time based on the position information of the vehicle included in the target probe information, and the ignition state of the vehicle included in the target probe information. Based on, the time when the vehicle turns off the ignition in the parking lot is calculated as the parking completion time. Then, the probe information analysis function calculates the time from the parking start time to the parking completion time as the actual time required for the vehicle to park. Further, in the present embodiment, the probe information analysis function determines the time from when the vehicle stops or slows down around the parking lot to when the vehicle completes parking, based on various information included in the target probe information. Can also be calculated as the actual time required for parking. Then, the probe information analysis function calculates the actual time required for the vehicle to park for each vehicle and for each date and time based on the plurality of target probe information acquired from the plurality of vehicles.

In step S205, the required parking time is calculated for each parking lot by the probe information analysis function. Specifically, the probe information analysis function groups a plurality of actual required times for each vehicle and each date and time calculated in step S204 for each parking lot, and groups the plurality of actual required times for each parking lot. An index value (for example, average value, median value, or mode value) can be calculated for each parking lot as the required parking time.

In step S206, attribute information is acquired by the probe information analysis function. For example, the probe information analysis function can be used for forward / backward movement specified based on the accelerator opening, brake opening, steering angle, acceleration in three axial directions, and air pressure in the parking lot included in the probe information. Whether the parking lot is "flat" or "three-dimensional" based on the number of repetitions, the number of times the front window is opened and closed, the time (number of times) the door is opened and closed, and whether there is a barrier at the entrance or exit of the parking lot. It is possible to determine whether the parking lot is a tread plate type or the parking difficulty level of the parking lot, and acquire the determination result as attribute information.

In step S207, the information on the required parking time calculated in step S205 and the attribute information acquired in step S206 are associated with each parking lot by the probe information analysis function and stored in the database 230.

You may. Such index values include, for example, an approximate time to parking (eg, "approximately 10 minutes to park" or "approximately 30 minutes to park"), a fixed time range (eg, "10 to 15 minutes", " You can use "30-45 minutes", "1 hour or more", etc.) and recommended degrees (eg, "recommended", "wait a little", "should be avoided", etc.).

Further, in the present embodiment, when there are a plurality of parking lots around the target vehicle or the destination of the target vehicle, the information presentation function can present the parking lot information of the plurality of parking lots in order of priority. .. For example, the information presentation function can be configured such that the parking lots with the shortest parking time are prioritized and the parking lot information is arranged in the order of the shortest parking time.

Further, in the present embodiment, the information presenting function sets the parking required time included in the parking lot information as the time required for the target vehicle to enter the parking lot after starting parking and the target vehicle entering the parking lot. It can also be presented later by dividing it into the time required to complete parking. This allows the driver to select a parking lot according to his / her preference. In addition, by presenting the time required for the target vehicle to enter the parking lot after starting parking and the time required for the target vehicle to complete parking after entering the parking lot, other occupants can be presented separately. It is also possible to let the driver decide to lower the vehicle first and move only the driver to the parking position, or to lower the other occupants first and wait only for the driver around the parking lot (do not park).

In addition, in the present embodiment, the driver can set the attribute information of the parking lot to be presented to the driver via the input device (not shown). For example, in the attribute information, the driver indicates whether the parking lot is "flat" or "three-dimensional", there is a barrier at the entrance or exit of the parking lot, the parking lot is a tread plate type, or the parking lot is difficult to park. Of the degrees, it is possible to select which information is to be presented to the driver with priority.

As a result, attribute information suitable for the driver's preference can be presented preferentially to the driver. In addition, it is possible to give priority to the parking lot information of the parking lot that suits the driver's preference and present it to the driver. For example, if the driver prefers a "flat parking lot", the "flat parking lot" can be preferentially presented to the driver.

In step S307, the information presentation function of the vehicle-mounted control device 140 determines whether or not the ignition has been turned off. When the ignition is on, the process returns to step S301, and the information providing process shown in FIG. 4 is repeated at regular intervals. Then, when the ignition is turned off, the information providing process shown in FIG. 4 is terminated.

To specify. Then, when the request for parking lot information is received from the in-vehicle device 100 of the target vehicle, the parking lot information of the parking lot around the target vehicle or the destination of the target vehicle is transmitted to the in-vehicle device 100 of the target vehicle. Thereby, the in-vehicle device 100 of the target vehicle can present, for example, information on the parking required time of the target vehicle or the parking lot existing around the destination of the target vehicle to the driver. As a result, the driver of the target vehicle can be made to grasp the time required for parking the vehicle in each parking lot, and the driver of the target vehicle can be made to select a parking lot suitable for parking. Further, in the present embodiment, by outputting information based on the required parking time, a parking lot can be parked relatively quickly by waiting for parking for a while even if the vehicle is full, or conversely, a parking lot even if there is an empty vehicle.

It should be noted that the embodiments described above are described for facilitating the understanding of the present invention, and are not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

For example, in the above-described embodiment, a configuration for providing parking lot information of a target vehicle or a parking lot around the destination of the target vehicle is illustrated, but a plurality of parking lots are provided around the target vehicle or the destination of the target vehicle. If there is, it may be configured to provide parking information of all of these parking lots, or it may be configured to provide only parking information of one to several parking lots having the shortest parking time. Good. Further, in the above-described embodiment, the configuration of providing the parking lot information of the target vehicle or the parking lot around the destination of the target vehicle is illustrated, but the in-vehicle device 100 of the target vehicle provides the information of the planned travel route. By transmitting to the device 200, the parking lot information of the parking lot along the planned travel route may be provided. Further, in the above-described embodiment, the information providing device 200 illustrates a configuration in which a plurality of parking lots are searched around the target vehicle or the destination of the target vehicle, but the information providing device 200 provides all parking lot information. It may be configured to transmit to the in-vehicle device 100 and search for a plurality of parking lots in the vicinity of the target vehicle or the destination of the target vehicle in the in-vehicle device 100.

Further, in the above-described embodiment, a configuration in which the required parking time is calculated for each parking lot is illustrated, but the present invention is not limited to this configuration, and the required parking time is set for each parking lot, each vehicle size, each day of the week, and the time zone. It can be configured to be calculated for each. For example, the information providing device 200 identifies the size, day of the week, or time zone of the vehicle from which the target probe information has been acquired based on the vehicle type information and time information of the vehicle included in the target probe information, thereby indicating the required parking time. Can be calculated for each parking lot, each vehicle size, each day of the week, and each time zone. Then, the information providing device 200 specifies the size of the target vehicle, the day of the day, and the required parking time corresponding to the time zone based on the vehicle type information and the date and time information of the target vehicle acquired from the target vehicle, thereby determining the size of the target vehicle. Information on the required parking time according to the day and time zone can be transmitted to the in-vehicle device 100 of the target vehicle. As a result, it is possible for the driver of the target vehicle to grasp the highly accurate parking required time that is more suitable for the situation of the target vehicle. In particular, when the size of the vehicle is large, it may take a long time to park when the parking lot is small, and in a parking lot for light vehicles or a parking lot for tall vehicles in a multi-story parking lot. May be specially provided, and the required parking time may vary greatly depending on the size of the vehicle. Even in such a case, according to the above embodiment, the driver is presented with an appropriate required parking time. be able to.

Further, in the above-described embodiment, a configuration in which the required parking time is calculated for each parking lot is illustrated, but the present invention is not limited to this configuration, and for example, the required parking time is set from the entry into the parking lot to the completion of parking. It can be configured to be calculated for each distance. For example, by calculating the required parking time for each mileage in the parking lot after the vehicle enters the parking lot, if the site area of the parking lot is large, the required parking time is at least the parking lot. Information indicating the convenience of the parking lot, such as being far from the entrance and being close to the entrance of the parking lot but requiring a long parking time, can be presented to the driver. For example, as such information, parking lot information can be presented to the driver of the target vehicle, such as waiting for ○ minutes at a place near the entrance of the parking lot and waiting for △ minutes at a place far from the entrance of the parking lot.

Further, in the above-described embodiment, a configuration in which the required parking time is calculated for each parking lot is illustrated, but the present invention is not limited to this configuration. For example, the parking lot site is divided into a plurality of areas and parking is performed for each area. It can be configured to calculate the required time. As a result, it is possible to statistically calculate the area that takes time and the area that can be stopped immediately in the parking lot and present it to the driver of the target vehicle. For example, within the premises of the same parking lot, the required parking time can be presented such that area A1 waits for ○ minutes and area A2 waits for Δ minutes.

Further, in the above-described embodiment, a configuration in which the driver is provided with information based on the parking time required for the parking action from the start of parking of the vehicle to the completion of parking has been illustrated, but in addition to this configuration, For example, the exit time from when the vehicle is released from parking to when the vehicle advances from the parking lot can be provided together with the required parking time.

Further, in addition to the above-described embodiment, the parking required time can be calculated separately for the full state and the empty state of the parking lot. For example, the information providing device 200 acquires the fullness information of the parking lot from an external server that manages each parking lot in association with the date and time, so that the probe information acquired from each vehicle is acquired in the full state. It is possible to determine whether the vehicle was acquired in an empty state. Then, the information providing device 200 determines the parking required time of the parking lot when the car is full based on the probe information acquired in the full state, and parks the parking lot when the car is empty based on the probe information acquired in the empty state. The required time can be calculated. As a result, when the parking lot to which the parking lot information is provided is full, the information providing device 200 can provide the parking required time when the parking lot is full, and the parking lot information is provided. When the parking lot is vacant, the parking lot can provide the required parking time when the parking lot is vacant. As a result, the driver of the target vehicle can appropriately grasp the parking time required according to the fullness of the parking lot.

Further, in the above-described embodiment, the configuration in which the accelerator opening is detected as the operating amount of the accelerator pedal and the brake opening is detected as the operating amount of the brake pedal is illustrated, but the configuration is not limited to this configuration, and for example, the operation of the accelerator pedal is performed. The amount of depression of the accelerator pedal may be detected as the amount, and the amount of depression of the brake pedal may be detected as the amount of operation of the brake pedal.

Further, in the present embodiment, the configuration in which the information providing device 200 transmits the parking lot information to the in-vehicle device 100 of the target vehicle is illustrated, but the present invention is not limited to this configuration, and for example, the information providing device 200 provides the parking lot information. It may be configured to be transmitted to a mobile terminal owned by the driver of the target vehicle.

The controller according to the above-described embodiment corresponds to the server processing device 220 of the information providing device 200 of the present invention.
