Description

  The present invention relates to a driving support device for a vehicle, and more particularly to a driving support device that can acquire a driving support plan in advance.

  A navigation device mounted on a vehicle calculates a travel route from the current position (departure point) of the vehicle to a destination (arrival point), displays a current position of the vehicle, a map, a travel route, etc. It has a function to guide the user to the destination by display. The calculation of a general travel route is searched by using efficiency of the travel distance, travel time, fuel consumption, etc. of the vehicle as a guideline. Some mobile terminals such as personal computers (PCs), tablet devices, and smartphones have the same functions as the navigation device.

  In recent years, an increasing number of vehicles have an ADAS (Advanced Driving Assistant System) function that supports a user's driving operation as a driving form of the vehicle. As an advanced ADAS function in the future, an automatic driving function for automatically driving a vehicle regardless of a user's driving operation has been proposed. In such an ADAS function (hereinafter, including an automatic driving function), for example, acquisition of the current position of the vehicle, acquisition of the lane in which the vehicle travels, and detection of the positions of other vehicles in the vicinity are performed, and the vehicle can be safely and comfortably Routes and speeds that can be traveled are calculated, and driving control assistance such as steering, drive source, and brake, or driving control is automated so that the vehicle travels according to the calculated routes and speeds.

  There is a merit that the burden on the driving operation of the user can be reduced or eliminated by the assistance of the driving control or the automation of the driving control. On the other hand, depending on road conditions and the surrounding environment, there are situations where it is difficult to travel using the ADAS function, and there is a possibility that part or all of the ADAS function cannot be executed. For example, driving assistance using the ADAS function due to situations where it is difficult to recognize lanes (white lines) by in-vehicle sensors such as cameras, tunnels where GPS (Global Positioning System) signals are difficult to receive, sudden accidents, or road constructions (hereinafter referred to as driving assistance) , A concept including automatic driving) may not be properly implemented.

  Japanese Patent Application Laid-Open No. 2005-228867 is a reason why automatic driving control cannot be performed when it is determined that automatic driving control cannot be performed at the present time or in the future during traveling in an automatic driving section in which automatic driving control of a vehicle is permitted. The technology of the automatic driving assistance device which acquires the reason for execution and also guides the reason for non-execution acquired together with the fact that automatic driving control cannot be performed is disclosed.

JP 2016-28927 A

  As described above, with the technique disclosed in Patent Document 1, the user can know the reason why the automatic driving control cannot be performed, but there is a problem that the user is limited to traveling.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a driving support device that can acquire a driving support plan even before the vehicle travels.

<Device configuration>
FIG. 1 is a block diagram showing a configuration of a vehicle ADAS device 100 according to the first embodiment of the present invention. As shown in FIG. 1, the vehicle ADAS device 100 includes a current position acquisition unit 101, a travel route calculation unit 102, an ADAS function application determination information acquisition unit 103 (application determination information acquisition unit), and ADAS function application condition determination. A notification unit 106 that notifies ADAS function application related information including an ADAS function application plan, an ADAS function application plan planning unit 105, and an ADAS function application plan planning unit 105 (application condition determination unit); The vehicle ADAS device 100 also includes a control unit (not shown) that controls the operation flow of the vehicle ADAS device 100.

  The current position acquisition unit 101 acquires the absolute position (latitude and longitude) of the vehicle acquired from GPS (Global Positioning System) and information (sensor information) detected by the vehicle speed sensor (not shown) and the direction sensor (not shown). ) Is used to calculate the current position of the vehicle. The current position of the vehicle calculated by the current position acquisition unit 101 is used for processing in which the travel route calculation unit 102 calculates a travel route.

  Further, the current position of the vehicle may be specified based on information obtained by the current position acquisition unit 101 communicating with the external device 131. Thereby, the load of the current position acquisition unit 101 can be reduced as compared with the case where the current position acquisition unit 101 calculates.

  Note that the current position acquisition unit 101 may acquire an arbitrary position different from the current position of the vehicle as a departure place instead of the current position of the vehicle. In this case, for example, there is a method in which the user designates the departure place using a map of a navigation device (not shown) mounted on the vehicle. The ADAS function application plan is not necessarily designed with the current position of the vehicle as the departure place, but corresponds to the case where the position far from the current position is planned as the departure place, such as when planning a tomorrow's travel plan. Can do.

  The travel route calculation unit 102 uses the map data to travel the travel route from the current position (departure point) of the vehicle calculated by the current position acquisition unit 101 to the destination (arrival point) set by the user. Efficiency such as distance, travel time, and fuel efficiency is calculated as a target function. In addition, although a user inputs information, such as a destination, into the ADAS apparatus 100 for vehicles through a user interface (a touch panel, a touch key, etc.) not shown, illustration is abbreviate | omitted for simplification.

  In addition to the travel route, the travel route calculation unit 102 can also calculate a departure time from the departure place and an estimated arrival time at the destination. Here, since the map data includes information other than that used for navigation, the information on the vehicle travel route output from the travel route calculation unit 102 includes an ADAS function application determination information acquisition unit 103 described later. Various information used as input may be included.

  The map data used by the travel route calculation unit 102 is stored in advance in a storage device (not shown), but various information included in the map data may change due to road construction and natural phenomena. It is good also as a structure updated to higher quality information including the newest information by communicating with outboard equipment 131, such as an infrastructure equipment outside a vehicle, and another vehicle. Thereby, the ADAS function application plan based on the latest data can be obtained.

  The update of the map data stored in the storage device is normally performed in a state where the travel route calculation unit 102 is not operating or the vehicle ADAS device 100 is not used.

  The storage device is nonvolatile or volatile, such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), etc. In addition to the semiconductor memory, a storage medium that requires a drive device such as a hard disk, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, and a DVD (Digital Versatile Disc) is applicable.

  The storage device not only stores acquired data such as map data, but also stores processed or generated data, and may be configured for each configuration of the vehicle ADAS device 100 or the vehicle ADAS device. One storage device may be shared by 100 as a whole.

  The ADAS function application determination information acquisition unit 103, in addition to the input information from the travel route calculation unit 102, ADAS function application determination for determining whether the ADAS function installed in the vehicle can be applied to the travel route. Get information.

  The ADAS function application determination information, such as map data, road characteristic information, etc., is determined before the vehicle travels and does not change for a long time and is acquired before the vehicle travels. These can be stored in advance in a storage device, and the ADAS function application determination information acquisition unit 103 can acquire ADAS function application determination information therefrom.

  The ADAS function application determination information also includes unconfirmed information that has not been confirmed before the vehicle travels, such as lane restrictions and weather conditions that change in a short period of time or change suddenly. Such information can be obtained from the infrastructure equipment outside the vehicle and the outside equipment 131 such as another vehicle immediately before the start of traveling of the vehicle and during traveling, so that the latest information can be obtained.

  As described above, since the ADAS function application determination information includes not only confirmed information but also unconfirmed information, a more accurate ADAS function application plan can be obtained.

  The ADAS function application determination information acquired by the ADAS function application determination information acquisition unit 103 can be stored in the storage device described above. In this case, when the ADAS function application determination information acquisition unit 103 acquires higher-quality ADAS function application determination information including the latest information, the data stored in the storage device is updated.

  Various ADAS functions have a condition that the ADAS function cannot be executed depending on the function and performance. For example, when it is necessary to recognize the white line on the road in the ADAS function using the camera, the ADAS function cannot be executed on the road of the white line that has disappeared. In addition, when the ADAS function using the radar has a speed limit, the ADAS function cannot be executed on a road where the speed limit cannot be observed. For example, Adaptive Cruise Control (ACC), which uses radar to keep the distance between vehicles constant, is also available as a vehicle speed limit type. For example, in Adaptive Cruise Control that operates at 35 km / h or higher, there is a limit. On roads with a speed of 30 km / h and roads where the traffic flow is basically 30 km / h or less, the speed limit (speed limit as an ADAS function application condition) cannot be observed, and the ADAS function cannot be executed.

  Here, a specific example of the ADAS function application determination information acquired by the ADAS function application determination information acquisition unit 103 will be described. The fixed information includes, for example, road type information such as an expressway, a motorway, a main road, a general road in a city area, a general road in a suburban area, and a mountain road, and also includes altitude information (that is, gradient information), road Examples include road characteristic information such as width, curvature of a road, number of road lanes, traffic lights, and road signs. In addition, information on the complexity of the road, such as the presence / absence and number of road junctions and the number of road intersections. These can be obtained from map data and topographic data. Further, information such as speed limit, predicted speed information indicating the vehicle speed range (vehicle flow) predicted on each road, tunnel, lane definition, presence / absence of communication means outside the vehicle, and the like are also included.

  Further, as the unconfirmed information, there is information that changes depending on external factors such as a vehicle schedule, weather conditions, and traffic conditions. For example, in addition to information that is specified based on time and date, such as morning, evening, and season, and that can be obtained mainly from in-vehicle clocks, weather information such as weather, humidity, and temperature, road regulation information due to construction and entertainment, etc. Information that can be acquired mainly by communication with devices outside the vehicle, such as information on traffic conditions such as traffic jams and other vehicles in the vicinity, and failure information on communication infrastructure.

  The ADAS function application condition determination unit 104 determines application conditions for various ADAS functions installed in the vehicle. The output of the ADAS function application condition determination unit 104 is information used by the ADAS function application plan planning unit 105 and is unique information of the ADAS function installed in the vehicle, so it is not frequently changed. Usually, it is held in advance in the storage device as ADAS function application condition data.

  However, in recent ADAS functions, there are ADAS function-equipped products that can be retrofitted even though they are not installed at the time of vehicle purchase. Since the ADAS function application condition is changed by retrofitting the ADAS function, in this case, it is necessary to update the vehicle-specific information held in advance. The ADAS function application condition determining unit 104 can cope with the change of the ADAS function by determining the ADAS function application condition using the updated condition.

  Examples of ADAS functions include adaptive cruise control, lane keeping (lane keeping) support system, off-road departure suppression function, sign recognition function, lane change support, overtaking support for low-speed or stopped vehicles, and driving support such as traffic jam tracking Functions. In addition, an automatic driving function that is an advanced type of the ADAS function is also mentioned.

  Here, the ADAS function application condition in the ADAS function application condition determination unit 104 will be described by taking a lane keeping support system using a camera as an in-vehicle sensor as an example. When recognizing a white line that defines a lane using a camera, it is assumed that the information about the definition of the white line is acquired in advance by the ADAS function application determination information acquisition unit 103 as road characteristic information. For example, the ADAS function application determination information acquisition unit obtains the white line sharpness information classified into three levels, with the highest sharpness being level 1, medium sharpness being level 2, hard-to-see sharpness being level 3, and so on. 103 has. In a lane keeping support system using a high-performance camera (defined by resolution, etc.), the lane keeping is maintained when the lane is defined by a white line with a sharpness level of 1 or 2 in the ADAS function application condition determination unit 104. Judge that the support system is applicable. In a lane keeping support system using a low-performance camera (defined by resolution, etc.), it may be determined that the lane keeping support system can be applied only to roads where the lane is defined by a white line with a sharpness level of 1. .

  Even when a high-performance camera is in bad weather and at night, it may be assumed that the lane keeping support system cannot be used even on a road with a clear white line level 2, and the application of the lane keeping support system may be conditional. In that case, the ADAS function application condition determination unit 104 determines the ADAS function application condition with a condition in which, for example, the condition of whether it is night or not is added in addition to the condition of the sharpness of the white line. In addition to the impossible two-stage application conditions, a three-stage application condition such as “applicable with conditions” may be used, or more multiple stages of conditions may be used. Examples of the ADAS function application conditions of three or more stages include conditions indicating the possibility (probability) that the ADAS function can be applied. Further, as an example of the multi-stage condition, a speed limit in the adaptive cruise control of the vehicle speed limit type can be mentioned.

  In this way, by making the ADAS function application conditions into a plurality of conditions, an ADAS function application plan with many options can be obtained.

  The ADAS function application planning unit 105 includes ADAS function application determination information input from the ADAS function application determination information acquisition unit 103 before or during the travel of the travel route input from the travel route calculation unit 102, and ADAS. Using the ADAS function application condition input from the function application condition determining unit 104, the applicability or the applicability level of whether or not various ADAS functions mounted on the vehicle can be applied on the input travel route is determined. An ADAS function application plan is drawn up based on the determination result.

  Since the ADAS function application plan is formulated using the conditions input from the ADAS function application conditions, it may be a two-stage plan for determining applicability as well as the ADAS function application conditions, and the ADAS function application A plan of three or more stages for determining the availability level may be used. The ADAS function application plan having three or more stages includes, for example, a plan indicating the possibility (probability) that the ADAS function can be applied, in addition to the application plan that can be applied and cannot be applied.

  Since the ADAS function application condition varies depending on the characteristics of various ADAS functions, the ADAS function application plan planning unit 105 may formulate an ADAS function application plan for each ADAS function. Thereby, an application plan suitable for each ADAS function can be made.

  When various ADAS functions have no dependency relationship and function independently, the ADAS function application plan generated by the ADAS function application plan planning unit 105 is an independent plan for each ADAS function. On the other hand, when various ADAS functions have a dependency relationship and may influence each other, the ADAS function application plan planning unit 105 drafts an ADAS function application plan in consideration of the influence for each ADAS function.

  The notification unit 106 notifies the user 132 such as a driver about ADAS function application related information including the ADAS function application plan planned by the ADAS function application plan planning unit 105. Examples of notification in the notification unit 106 include visual notifications such as a liquid crystal display, a head-up display, a head-mounted display, and a warning lamp, audio notifications, auditory notifications such as warning sounds, and tactile notifications that apply vibration to a part of the body. Can be mentioned. By adopting these notification modes, the ADAS function application plan can be easily notified to the user.

  The main configuration of the vehicle ADAS device 100 other than the notification unit 106 can be configured using a computer, and each of these configurations is realized by the computer executing a program. That is, the current position acquisition unit 101, the travel route calculation unit 102, the ADAS function application determination information acquisition unit 103, the ADAS function application condition determination unit 104, and the ADAS function application plan planning unit in the vehicle ADAS device 100 illustrated in FIG. 105 is realized by the processing circuit 10 shown in FIG. 2, for example. A processor such as a CPU (Central Processing Unit) or a DSP (Digital Signal Processor) is applied to the processing circuit 10, and the functions of the above components are realized by executing a program stored in a storage device.

  Note that dedicated hardware may be applied to the processing circuit 10. When the processing circuit 10 is dedicated hardware, the processing circuit 10 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a processor programmed in parallel, an ASIC, an FPGA, or a combination thereof. To do.

  Also, FIG. 3 shows the components of the ADAS device 100 for vehicle shown in FIG. 1 (current position acquisition unit 101, travel route calculation unit 102, ADAS function application determination information acquisition unit 103, ADAS function application condition determination unit 104. And the hardware configuration in the case where the ADAS function application planning unit 105) is configured using a processor. In this case, the function of each component of the vehicle ADAS apparatus 100 is realized by a combination of software and the like (software, firmware, or software and firmware). Software or the like is described as a program and stored in the memory 12. The processor 11 functioning as the processing circuit 10 implements the functions of the respective units by reading out and executing the program stored in the memory 12 (storage device).

<Operation>
Next, the operation of the vehicle ADAS apparatus 100 will be described using the flowchart shown in FIG.

  When the vehicle or in-vehicle system is activated and the vehicle ADAS device 100 is operated, application of the operation flow of the vehicle ADAS device 100 is started (step S1). When application of the operation flow of the vehicle ADAS device 100 is started, first, the current position acquisition unit 101 acquires the current position of the vehicle (step S2). The current position of the vehicle may be automatically acquired by the current position acquisition unit 101 based on the absolute position of the vehicle acquired from the GPS and sensor information detected by the speed sensor of the vehicle. May be set via the user interface. Further, as described above, instead of the current position of the vehicle, a departure place different from the current position of the vehicle may be set via the navigation device mounted on the vehicle or the user interface dedicated to the ADAS device 100 for vehicles. good.

  Next, the travel route calculation unit 102 determines whether or not the travel route needs to be calculated (step S3). If the travel route has not been calculated or if it is necessary to recalculate the travel route, the process proceeds to step S4, where the travel route is calculated. Is calculated, and if the recalculation of the travel route is unnecessary, the process proceeds to step S9. Note that when the travel route needs to be recalculated, the travel route is already changed even if the travel route is already calculated, and ADAS function determination information is additionally acquired. Cases that may affect the ADAS function application plan.

  More specifically, when the ADAS function application determination information acquisition unit 103 obtains the latest information such as a traffic accident or weather prediction while traveling on the travel route, ADAS function determination information is added. As a result, the determination result may be updated.

  In step S4, the travel route calculation unit 102 calculates a travel route from the current position (departure point) of the vehicle to the set destination (arrival point). The destination may be set by the user of the vehicle ADAS device 100 using a user interface, or the travel route calculation unit 102 automatically sets the destination from a past travel history or the like. You may do it.

  When the travel route calculation unit 102 calculates the travel route of the vehicle, ADAS function application determination information for determining whether the ADAS function installed in the vehicle can be applied to the travel route is used for ADAS function application determination. The information acquisition part 103 acquires (step S5).

  After acquiring the ADAS function application determination information, the ADAS function application condition determination unit 104 determines application conditions for various ADAS functions mounted on the vehicle based on the ADAS function application determination information (step S6).

  The output of the ADAS function application condition determination unit 104 is information used by the ADAS function application plan planning unit 105 and is unique information of the ADAS function installed in the vehicle. In step S6, the data stored in the storage device is used, and once the ADAS function application condition is determined, the data is not changed during the operation of the vehicle ADAS device 100.

  Next, the ADAS function application planning unit 105 calculates various ADAS functions mounted on the vehicle in step S4 using the ADAS function application determination information acquired in step S5 and the ADAS function application conditions determined in step S6. An applicability or applicability level as to whether or not it can be applied in the travel route is determined, and an ADAS function application plan is created based on the determination result (step S7).

  Then, ADAS function application-related information including the ADAS function application plan prepared in step S7 is notified to a user such as a driver via the notification unit 106 (step S8).

  Thereafter, when a control unit (not shown) determines whether to end the application of the operation flow of the vehicle ADAS device 100 (step S9) and determines that the application of the operation flow of the vehicle ADAS device 100 ends, the operation flow Is finished (step S10). On the other hand, when it is determined that the application of the operation flow of the ADAS device 100 for vehicles is to be continued, the operation flow after step S2 is repeated. The determination as to whether or not the operation flow of the ADAS device 100 for vehicles is continued includes, for example, whether or not the vehicle has arrived at the destination and whether or not the user has instructed to stop the vehicle or the in-vehicle system. In addition, there may be a case where the vehicle ADAS device 100 or the in-vehicle system automatically determines termination, such as a vehicle failure or an emergency situation.

  FIG. 5 is a notification example of the ADAS function application plan shown in the notification unit 106, and shows an example of visual notification as video information on the liquid crystal display. In FIG. 5, the ADAS function application plan in the travel route from the departure place to the destination is shown for the ADAS function 1 and the ADAS function 2 installed in the vehicle. In the example of FIG. 5, for the ADAS function 1, an ADAS function application plan designed using three levels of ADAS function applicability levels of levels H 1, H 2, and H 3 is shown. That is, level H1 is a level at which ADAS function 1 can be applied unconditionally, level H2 is a level at which ADAS function 1 can be applied conditionally, and level H3 is a level at which ADAS function 1 cannot be applied. It is.

  As shown in FIG. 5, ADAS function 1 is generally applicable to mountain roads and trunk roads (level H1), but is also applicable to trunk roads with conditions (level H2). It is not applicable (level H3) at complicated intersections.

  Further, as shown in FIG. 5, for the ADAS function 2, an ADAS function application plan designed using three levels of ADAS function applicability levels L1, L2, and L3 is shown. That is, level L1 is a level at which the ADAS function 2 application probability is 100%, level L2 is a level at which the ADAS function 2 application probability is 80%, and level L3 is an ADAS function 2 application probability of 0%. It is a level that becomes.

  As shown in FIG. 5, the ADAS function 2 has an application probability of 80% (level L2) on mountain roads, but has an application probability of 100% (level L1) on main roads. However, the application probability is 0% (level L3) at a complicated intersection even on a main road.

  The user of the vehicle ADAS device 100 looks at the ADAS function application plan as shown in FIG. 5 and sees whether or not various ADAS functions can be applied in the travel route before or during travel, and various ADAS functions. It is possible not only to determine which ADAS function to use, but also to take measures to change the travel route so that the level H1 or L1 area is expanded. It becomes.

<Modification>
The vehicle ADAS apparatus 100 shown in FIG. 1 includes a travel route calculation unit 102, and the travel route calculation unit 102 calculates a travel route, a departure time, an estimated arrival time, and the like of the vehicle. For example, a configuration may be employed in which information such as a travel route calculated by a navigation device mounted on a vehicle is used without using the calculation unit 102.

  FIG. 6 is a block diagram showing a configuration of a vehicle ADAS device 100A according to a modification of the first embodiment. In FIG. 6, the same components as those in the vehicle ADAS device 100 described with reference to FIG. 1 are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 6, the vehicle ADAS device 100 </ b> A includes a travel route acquisition unit 109 instead of the travel route calculation unit 102, and the vehicle travel route, departure time, and arrival prediction calculated by the external navigation device 141. It is configured to acquire time and the like.

  By adopting such a configuration, the map data and road characteristic information held in the navigation device 141 can be used, so that it is not necessary to hold such information in the vehicle ADAS device 100A. When the navigation device 141 can use a communication function or a communication function such as a mobile phone or a smartphone, the map data and the road characteristic information are, for example, those that are distributed from an external device 131 such as a map service company via a communication network. You may do it.

<Device configuration>
FIG. 7 is a block diagram showing a configuration of the vehicle ADAS device 110 according to the second embodiment of the present invention. As shown in FIG. 7, the vehicle ADAS device 110 includes a current position acquisition unit 101, a travel route calculation unit 102, an ADAS function application determination information acquisition unit 103, an ADAS function application condition determination unit 104, and an ADAS function application plan. Unit 105, ADAS function application determining unit 111 (application determining unit), ADAS function executing unit 112 (function executing unit), and a notifying unit 113 for reporting ADAS function application related information including an ADAS function application plan and an ADAS function application status. ing. In FIG. 7, the same components as those in the vehicle ADAS device 100 described with reference to FIG. The vehicle ADAS apparatus 110 also includes a control unit (not shown) that controls the operation flow of the vehicle ADAS apparatus 110.

  Information (data) on the current position of the vehicle calculated by the current position acquisition unit 101 is input to the travel route calculation unit 102 and used for the travel route calculation process, and is input to the ADAS function application determination unit 111. It is used for processing to determine the current travel position of the vehicle. Similarly to the first embodiment, the travel route calculation unit 102 may acquire an arbitrary position different from the current position of the vehicle as a departure place instead of the current position of the vehicle. However, even in this case, the ADAS function application determination unit 111 receives information on the current position of the vehicle.

  The travel route calculation unit 102, the ADAS function application determination information acquisition unit 103, the ADAS function application condition determination unit 104, and the ADAS function application plan planning unit 105 have the same functions as those in the first embodiment, but the ADAS function application plan planning. The ADAS function application plan planned by the unit 105 is output to the ADAS function application determination unit 111 and the notification unit 113.

  The ADAS function application determination unit 111 applies the ADAS function based on the current position of the vehicle input from the current position acquisition unit 101 according to the ADAS function application plan in the travel route input from the ADAS function application plan planning unit 105. The determination of availability is sequentially performed, and an ADAS function application instruction for instructing application of various ADAS functions to the ADAS function execution unit 112 is output. That is, while confirming the ADAS function application plan in the travel route, it is determined from the information on the current position of the vehicle where the host vehicle is present in the travel route, and whether or not the ADAS function can be applied in that location is determined. Then, the application status of the ADAS function is output to the notification unit 113.
