Embodiments for Carrying Out the Invention

[0010] Hereinafter, in the present disclosure, the drawings are associated with one or more embodiments. Also, in all the drawings, the same components are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0011] The information output device 10 is a device for assisting the driving of the target vehicle 20 and is used together with the in-vehicle device 30 mounted on the target vehicle 20.

[0012] The target vehicle 20 is a vehicle for logistics such as a truck or a dump truck. However, the target vehicle 20 may be a vehicle for transporting passengers such as a bus, or may be a private car. Further, the target vehicle 20 may be a so-called self-driving vehicle, or may be a vehicle that has a driver on board and performs automatic driving as necessary.

[0013] The information output device 10 acquires position information indicating the position of the target vehicle 20, and outputs driving assist information corresponding to this position information to the in-vehicle device 30. The driving assist information is information that can specify how to move the accelerator, brake, steering wheel, etc. of the target vehicle 20 when the driver or the control device of the target vehicle 20 moves the target vehicle 20 at that position, for example, when moving the target vehicle 20 along the road on which the target vehicle 20 is currently traveling.

[0014] The in-vehicle device 30 generates, for example, position information of the target vehicle 20 and transmits it to the information output device 10. Further, the in-vehicle device 30 controls the target vehicle 20 using, for example, the driving assist information acquired from the information output device 10. In this case, the output unit 130 is a control device for automatically driving the target vehicle 20. Further, the in-vehicle device 30 may perform processing to assist the driver of the target vehicle 20 in driving the target vehicle 20 along the driving assist information. An example of this processing is to output information indicating how to move at least one of the accelerator, brake, and steering wheel of the target vehicle 20 at that position each time the target vehicle 20 moves. This output may be performed by display on a display or by voice output.

[0015] Note that the in-vehicle device 30 may be a device that is pre-hated by the target vehicle 20, or may be a device brought into the target vehicle 20 by a passenger of the target vehicle 20. In the latter case, the in-vehicle device 30 may be a portable communication device such as a so-called smartphone or a tablet-type device.

[0016] As shown in Figure 2, the information output device 10 includes, for example, a first acquisition unit 110, a second acquisition unit 120, and an output unit 130, and can use a storage unit 140. The storage unit 140 may be part of the information output device 10 or may be located outside the information output device 10.

[0017] The memory unit 140 stores various types of information used by the information output device 10. One example of this information is driving assistance information. The memory unit 140 stores location information in association with the driving assistance information that should be used at the location indicated by that location information.

[0018] Road conditions, such as whether or not the road is paved, the direction and magnitude of the slope, the presence and curvature of curves, and the width of the road, vary from road to road. Therefore, how to operate at least one of the accelerator, brake, and steering wheel will differ depending on the position where the vehicle 20 is traveling. Accordingly, the memory unit 140 stores driving assistance information appropriate to the position indicated by the position information, associating it with that position information.

[0019] The first acquisition unit 110 acquires location information of the target vehicle 20. This location information is generated, for example, by an on-board device 30. This location information may be, for example, latitude and longitude information generated by GPS, or it may be information that can identify roads that overlap with this latitude and longitude information, for example, information indicating links in map information. The first acquisition unit 110 repeatedly acquires location information from the target vehicle 20, for example, via a communication line.

[0020] The second acquisition unit 120 acquires driving assist information from the storage unit 140 that corresponds to the location information acquired by the first acquisition unit 110.

[0021] The output unit 130 outputs the driving assist information acquired by the second acquisition unit 120 to the on-board device 30 installed in the target vehicle 20. The on-board device 30 then performs the processing described using Figure 1.

[0022] In this way, the memory unit 140 stores location information in association with driving assistance information to be used at the location indicated by the location information. The information output device 10 then transmits the driving assistance information corresponding to the location of the target vehicle 20 to the in-vehicle device 30. Therefore, by using the information output device 10, the in-vehicle device 30 or the driver of the target vehicle 20 can use driving assistance information appropriate to the location of the target vehicle 20.

[0023] The memory unit 140 stores location information and driving assist information in association with each other, as shown in Figure 3, for example. In the example shown in this figure, one location information refers to a certain section of a road. The driving assist information is information indicating how the operating state of at least one, preferably all, of the accelerator, brake, and steering wheel changes as the vehicle moves through that section. This information is, for example, information that associates the operating state of the operating object in each of a plurality of latitude and longitude pieces of information indicating the extension state of the road. The scanning state of the operating object includes, for example, the amount the accelerator is pressed, the amount the brake is pressed, and the steering angle and direction.

[0024] As shown in Figure 4, the driving assistance information stored in the memory unit 140 may include information indicating how the position of the target vehicle 20 in the width direction of the road should change when the target vehicle 20 moves along the road, such as information corresponding to the driving trajectory, and the speed at each of several positions in the extension direction of the road. This information is, for example, information that associates multiple latitude and longitude information indicating the extension state of the road that the target vehicle 20 should travel on, the position that the target vehicle 20 should take in the width direction of the road in that latitude and longitude information, and the speed that the target vehicle 20 should maintain in that latitude and longitude information.

[0025] In the example shown in Figure 4, the device controlling the target vehicle 20, such as the in-vehicle device 30, controls the steering wheel and other components of the target vehicle 20 so that it is in the position indicated by the driving assist information, and also controls at least one of the accelerator and brake so that the speed of the target vehicle 20 approaches or matches the speed indicated by the driving assist information.

[0026] As shown in Figures 5 and 6, the storage unit 140 may further store driving assistance information according to vehicle attribute information. This is because even when driving in the same location, the appropriate driving assistance information may differ depending on the vehicle's attributes.

[0027] In the example shown in Figure 5, the vehicle attribute information includes the vehicle type. The definition of a vehicle type can vary. For example, a vehicle type may follow legal classifications such as large, medium, and small, or it may follow the classification of products sold by the automobile manufacturer.

[0028] In the example shown in Figure 6, the vehicle attribute information includes load weight in addition to vehicle type. This is because even for the same vehicle, appropriate driving assistance information can differ depending on the vehicle's attributes, such as load weight, for example, the weight of the cargo or the number of occupants. Note that the vehicle attribute information may include load weight but not vehicle type.

[0029] In the example shown in Figures 5 and 6, the first acquisition unit 110 of the information output device 10 acquires vehicle attribute information from, for example, the in-vehicle device 30. Vehicle type information is, for example, pre-registered in the in-vehicle device 30. The load weight is detected, for example, by a sensor mounted on the target vehicle 20. The second acquisition unit 120 then acquires driving assist information corresponding to the combination of location information and attribute information of the target vehicle 20 and transmits it to the in-vehicle device 30.

[0030] As shown in Figure 7, the memory unit 140 may further store driving assistance information separately for weather information. This is because even when driving in the same location, the appropriate driving assistance information may differ depending on the weather at that time. Weather information may include, for example, information indicating whether it is sunny, cloudy, rainy, or snowy, the presence or absence of fog, temperature, and humidity. However, the weather information is not limited to this example.

[0031] The first acquisition unit 110 then acquires weather information corresponding to the location information of the target vehicle 20. The first acquisition unit 110 may acquire the weather information from the in-vehicle device 30, or it may acquire it from a server that stores weather information by location. In the latter case, the first acquisition unit 110 reads the weather information corresponding to the location information acquired from the in-vehicle device 30 from this server. The first acquisition unit 110 may also acquire the location information of the sensor 40 and the weather information generated by the sensor 40 from the sensor 40, which will be described later.

[0032] The second acquisition unit 120 then acquires driving assistance information corresponding to the combination of the location information of the target vehicle 20 and the weather information corresponding to that location information, and transmits it to the in-vehicle device 30.

[0033] As shown in Figure 8, the storage unit 140 may further store driving assistance information separately for road surface information indicating the condition of the road surface. This is because even when driving in the same location, the appropriate driving assistance information may differ depending on the condition of the road surface at that time. The road surface information indicates, for example, whether it is dry, wet, or covered with snow or frozen. However, the road surface information is not limited to this example. The first acquisition unit 110 acquires road surface information from, for example, the in-vehicle device 30. However, the first acquisition unit 110 may also acquire the position information of the sensor 40 and the road surface information generated by the sensor 40 from the sensor 40, which will be described later.

[0034] The second acquisition unit 120 then acquires driving assist information corresponding to the combination of the location information of the target vehicle 20 and the road surface information corresponding to that location information, and transmits it to the in-vehicle device 30.

[0035] The information output device 10 has a hardware configuration that includes, for example, a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input / output interface 1050, and a network interface 1060, as shown in Figure 9.

[0036] Bus 1010 is a data transmission path for the processor 1020, memory 1030, storage device 1040, input / output interface 1050, and network interface 1060 to send and receive data to and from each other. However, the method of connecting the processor 1020 and the other components to each other is not limited to bus connection.

[0037] The 1020 processor is a processor implemented in components such as the CPU (Central Processing Unit) and GPU (Graphics Processing Unit).

[0038] Memory 1030 is a main memory device implemented using RAM (Random Access Memory), etc.

[0039] The storage device 1040 is an auxiliary storage device implemented as a removable media such as an HDD (Hard Disk Drive), SSD (Solid State Drive), or memory card, or as ROM (Read Only Memory), and has a recording medium. The recording medium of the storage device 1040 stores program modules that realize each function of the information output device 10 (for example, the first acquisition unit 110, the second acquisition unit 120, the output unit 130, and the memory processing unit 150 described later). The processor 1020 reads each of these program modules into the memory 1030 and executes them, thereby realizing each function corresponding to that program module. The storage device 1040 may also function as a storage unit 140.

[0040] The input / output interface 1050 is an interface for connecting the information output device 10 with various input / output devices. For example, the information output device 10 may communicate with the storage unit 140 via the input / output interface 1050.

[0041] The network interface 1060 is an interface for connecting the information output device 10 to a network. This network may be, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The method by which the network interface 1060 connects to the network may be wireless or wired. The information output device 10 may communicate with at least one of the in-vehicle device 30, the storage unit 140, and the sensor 40, which will be described later, via the network interface 1060.

[0042] The information output device 10 operates as shown in Figure 10, for example. First, the in-vehicle device 30 repeatedly generates location information for the target vehicle 20 and transmits it to the information output device 10. Each time the information output device 10 acquires location information from the in-vehicle device 30, it performs the following processing.

[0043] The first acquisition unit 110 of the information output device 10 acquires location information from the in-vehicle device 30 (step S10). Next, the second acquisition unit 120 of the information output device 10 acquires driving assist information corresponding to this location information from the storage unit 140 (step S20). Next, the output unit 130 transmits this driving assist information to the in-vehicle device 30 (step S30).

[0044] In this way, the information output device 10 can transmit driving assistance information corresponding to the position of the target vehicle 20 to the in-vehicle device 30. Therefore, the in-vehicle device 30 can use the appropriate driving assistance information to control, for example, the target vehicle 20.

[0045] The information output device 10 may operate as shown in Figure 11, for example. In this example, the information output device 10 transmits driving assistance information to the target vehicle 20 only when the target vehicle 20 is located in a predetermined location. This predetermined location information is stored in the storage unit 140 beforehand.

[0046] The first acquisition unit 110 of the information output device 10 acquires location information from the in-vehicle device 30 (step S10). Next, the second acquisition unit 120 of the information output device 10 checks whether this location information is included in a predetermined location, and if it is included in a predetermined location (step S12: Yes), proceeds to step S20. The subsequent processing is as explained with reference to Figure 10.

[0047] This reduces the load on the information output device 10.

[0048] The information output device 10 may be used in conjunction with the sensors 40, for example, as shown in Figure 12. The sensors 40 are arranged in multiple locations along a road, and each generates at least one of weather information and road surface information at its location, and transmits this information, along with information that identifies the location of the sensor 40, such as identification information for the sensor 40, to the information output device 10.

[0049] The sensor 40 may also generate driving information of a vehicle that has traveled on the road and transmit this driving information and the vehicle's position information at the time the driving information was generated to the information output device 10. The driving information includes information that can identify the vehicle's trajectory and the date and time of travel. The driving information may further include speed. In this case, the sensor 40 may have, for example, an imaging device.

[0050] The information output device 10 stores the information transmitted by the sensor 40 in the storage unit 140. The information output device 10 then uses this information to perform processing related to driving assistance information.

[0051] Furthermore, at least a portion of the driving information may be transmitted by the on-board device 30 to the information output device 10. In this case, the information transmitted by the on-board device 30 to the information output device 10 may include information that can identify the vehicle's trajectory, as well as a history of operations on at least one of the accelerator, brake, and steering wheel. The information output device 10 then stores the information transmitted by the on-board device 30 in the storage unit 140.

[0052] For example, the information output device 10 further includes a storage processing unit 150, as shown in Figure 13.

[0053] The memory processing unit 150 acquires vehicle location information and driving information from, for example, the sensor 40, and if the driving information meets the criteria, it acquires the driving information of the vehicle at the time the driving information was generated. The criteria used here include, for example, that the trajectory does not deviate from the road, that the trajectory does not include curves with a curvature less than or equal to a standard value, and that no sudden operations have been performed on at least one of the accelerator, brake, and steering wheel. In addition, the driving information includes at least all of the same items as the driving assist information.

[0054] An example of how the memory processing unit 150 acquires driving information is as follows. First, the memory unit 140 stores the driving history of multiple vehicles. This driving history includes at least information indicating where the vehicle was traveling at a given time, i.e., a history of combinations of location and date / time. When the memory processing unit 150 acquires driving information that meets the above criteria, it identifies the combination of date / time information and location information corresponding to that driving information, and identifies the vehicle whose driving history contains the information corresponding to this combination. Then, it acquires the driving information corresponding to the date / time information and location information from this vehicle.

[0055] The memory processing unit 150 then uses the acquired driving information to update the driving assist information stored in the memory unit 140, corresponding to the location information that corresponds to this driving information. This update may involve, for example, overwriting the driving assist information with the newly acquired driving information, or generating new driving assist information by statistically processing the already stored driving assist information and the newly acquired driving information. The memory processing unit 150 also Multiple pieces of acquired driving information may be stored, and new driving assistance information may be generated and stored in the storage unit 140 by repeatedly performing statistical processing on these pieces of information.

[0056] This allows driving assistance information to be easily stored in the memory unit 140.

[0057] The memory processing unit 150 may also store information in the memory unit 140 that indicates a predetermined location, i.e., a location where driving assistance information should be provided, as explained using Figure 11.

[0058] For example, the memory processing unit 150 acquires driving information for each of the multiple vehicles that traveled to the same location. If the acquired driving information meets the criteria, the memory processing unit 150 may store the location information corresponding to that location in the memory unit 140 as the location where driving assistance information should be provided. The memory processing unit 150 also performs processing to store driving assistance information in the memory unit 140 in association with this location information.

[0059] The criteria used here include, for example, the variability of multiple driving data exceeding a certain threshold. More specifically, this criterion is at least one of the following: the variability of the driving trajectory exceeds a certain threshold, the variability of the speed exceeds a certain threshold, and the variability of at least one operation of the accelerator, brake, and steering wheel exceeds a certain threshold.

[0060] In this way, information indicating the location where driving assistance information should be provided can be easily stored in the storage unit 140.

[0061] Before this process is performed, information indicating predetermined locations, i.e., locations where driving assistance information should be provided, may be generated using, for example, map information and stored in the memory unit 140. This process is performed, for example, by the memory processing unit 150. For example, the memory processing unit 150 may determine that at least one of the following is a location where driving assistance information should be provided: a road section located in a mountainous area, a road section where the elevation difference over a predetermined distance is greater than or equal to a standard value, or a road section where a predetermined number of curves with a curvature less than or equal to a standard value are continuous.
