Although not shown, the camera 20 may be arranged in the luggage compartment of the trunk room of the vehicle. Since the interior of the cargo compartment may not be bright enough to capture an image, it is preferable to arrange one or more lights 21 in the cargo compartment.

  Then, the control apparatus 10 of this embodiment is demonstrated. The control device 10 of the vehicle information providing apparatus 100 according to the present embodiment includes a ROM (Read Only Memory) 12 in which a program for presenting a captured image of a cargo that has collapsed to a passenger is stored, and the ROM. By executing the program, a CPU (Central Processing Unit) 11 as an operation circuit that functions as the vehicle information providing apparatus 100 and the vehicle information providing system 1, and a RAM (Random Access Memory) that functions as an accessible storage device ) 13.

  Although not particularly limited, the control device 10 of the vehicle information providing device 100 of the present embodiment includes an ECU (Electronic Control Unit) whose main component is a microcomputer, and a navigation device 70 capable of communicating with the control device 10 includes: Configured as a communication unit with display. The control device 10 acquires position information output from the various devices 60 described above and the position detection device 71 of the navigation device 70.

  The control device 10 of the vehicle information providing apparatus 100 according to the present embodiment has an image acquisition function, a vehicle information acquisition function, a detection function, an output function, and an output control function. Furthermore, the control apparatus 10 of this embodiment further has a positional information acquisition function and a storage function according to the implementation. The control device 10 of the present embodiment is a computer that executes each function by cooperation of software for realizing the above function and the above-described hardware.

  Hereinafter, each function of the vehicle information providing apparatus 100 according to the present embodiment will be described.

  First, the image acquisition function of the control apparatus 10 of this embodiment is demonstrated. The control device 10 acquires a captured image captured by the camera 20. The camera 20 images the interior of the vehicle. The illumination 21 irradiates light into the cargo compartment of the vehicle. The acquired captured image is presented on the display 31 at an appropriate timing. The occupant can confirm the collapse state of the cargo loaded on the host vehicle from the presented captured image.

  The vehicle information acquisition function of the control apparatus 10 of this embodiment is demonstrated. The control device 10 acquires vehicle information detected by the vehicle controller 50, the various devices 60, and the navigation device 70 in the vehicle. The vehicle information may be acquired directly from the vehicle controller 50, the various devices 60, and the navigation device 70, or may be acquired from the various devices via the vehicle controller 50. The vehicle information obtained from the various devices 60 includes longitudinal acceleration information obtained from the longitudinal acceleration sensor 61, lateral acceleration information obtained from the lateral acceleration sensor 62, vehicle speed information obtained from the vehicle speed sensor 63, and brake opening sensor 64. Examples of the brake opening to be acquired, accelerator opening information acquired from the accelerator opening sensor 65, steering angle information acquired from the steering angle sensor 66, time information acquired from the clock 67, and the like can be given.

  The detection function of the control apparatus 10 of this embodiment is demonstrated. The control apparatus 10 detects the generation | occurrence | production timing in which the trigger of the collapse of the cargo loaded on the vehicle generate | occur | produces based on the acquired vehicle information. The trigger for collapse of cargo loaded on a vehicle is a movement of the vehicle that applies an external force to the cargo in the vehicle. Such movement of the vehicle is detected based on the vehicle information described above. For example, if the vehicle has a large speed fluctuation or rudder angle fluctuation, it can be predicted that the movement of the vehicle due to the speed fluctuation or rudder angle fluctuation will cause the cargo to collapse. It can be the occurrence timing of the trigger of the cargo collapse.

  The control device 10 of the present embodiment acquires the longitudinal acceleration of the vehicle over time from the longitudinal acceleration sensor 61 provided in the vehicle, and loads the timing at which the acquired longitudinal acceleration becomes equal to or greater than a first predetermined value on the vehicle. This is detected as the occurrence timing of the cargo collapse trigger. When longitudinal acceleration equal to or greater than the first predetermined value occurs in the vehicle, it is estimated that the movement of the vehicle is likely to cause collapse of the cargo. In other words, in this embodiment, when the longitudinal acceleration is less than the third predetermined value and the longitudinal acceleration is greater than or equal to the first predetermined value and the cargo collapse occurs immediately, the cargo collapses immediately. Rather than occur, it is assumed that cargo collapse will occur after a predetermined time has elapsed or at a predetermined timing when other conditions occur.

  Moreover, the control apparatus 10 of this embodiment acquires the longitudinal acceleration of the said vehicle from the longitudinal acceleration sensor 61 with which a vehicle is provided, and the timing when the acquired longitudinal acceleration became more than the 3rd predetermined value larger than a 1st predetermined value. This can be detected as an emergency occurrence timing with a high possibility of cargo collapse. In the present embodiment, when a large longitudinal acceleration greater than a third predetermined value that is greater than the first predetermined value occurs in the vehicle, it is estimated that there is a high possibility that the collapse of the cargo will immediately occur. The control device 10 detects a timing at which a large lateral acceleration of the third predetermined value or more has occurred in the vehicle as an emergency occurrence timing at which cargo collapse is likely to occur.

  The longitudinal acceleration of the first predetermined value that may cause cargo movement in the cargo compartment of the vehicle and cause the collapse of the cargo depends on the vehicle size, vehicle weight, vehicle driving / braking performance, and other vehicle specifications. Accordingly, it is appropriately defined experimentally or by simulation. Similarly, the longitudinal acceleration of the third predetermined value that causes the cargo in the cargo compartment of the vehicle to collapse immediately is appropriately determined experimentally or by simulation according to the size of the vehicle, the weight of the vehicle, the steering performance of the vehicle, and other vehicle specifications. Defined in Incidentally, the occurrence of cargo collapse is affected by the size and weight of the cargo. When setting the first predetermined value and the third predetermined value, the standard size of the cargo based on the size of the cargo space of the vehicle and the standard weight of the cargo based on the loadable weight of the vehicle are set. It is preferable to set.

  The control device 10 of the present embodiment acquires the lateral acceleration of the vehicle over time from the lateral acceleration sensor 62 included in the vehicle, and loads the timing at which the acquired lateral acceleration is equal to or greater than a second predetermined value on the vehicle. This is detected as the occurrence timing of the cargo collapse trigger. When lateral acceleration of the second predetermined value or more occurs in the vehicle, it is estimated that there is a high possibility that the movement of the vehicle will eventually cause a load collapse. That is, in this embodiment, when the lateral acceleration is greater than or equal to the second predetermined value and a large lateral acceleration less than the fourth predetermined value that causes the cargo collapse immediately occurs in the vehicle, the cargo collapses immediately. Rather than occur, it is assumed that cargo collapse will occur after a predetermined time or when other conditions occur.

  Moreover, the control apparatus 10 of this embodiment acquires the lateral acceleration of the said vehicle from the lateral acceleration sensor 62 with which a vehicle is provided, and the timing when the acquired lateral acceleration became more than the 4th predetermined value larger than a 2nd predetermined value. This can be detected as an emergency occurrence timing with a high possibility of cargo collapse. In the present embodiment, when a large lateral acceleration greater than a fourth predetermined value that is greater than the second predetermined value occurs in the vehicle, it is estimated that there is a high possibility that cargo collapse will occur immediately. The control device 10 detects a timing at which a large lateral acceleration of the fourth predetermined value or more has occurred in the vehicle as an emergency occurrence timing at which the cargo collapse is likely to occur.

  The lateral acceleration of the second predetermined value that may cause the cargo in the cargo compartment of the vehicle to move and collapse may depend on the size of the vehicle, the weight of the vehicle, the driving / braking performance of the vehicle, and other vehicle specifications. Accordingly, it is appropriately defined experimentally or by simulation. Similarly, the fourth predetermined lateral acceleration that causes the cargo in the cargo compartment to collapse immediately is appropriately determined experimentally or by simulation depending on the size of the vehicle, the weight of the vehicle, the steering performance of the vehicle, and other vehicle specifications. Defined in Incidentally, the occurrence of cargo collapse is affected by the size and weight of the cargo. When setting the second predetermined value and the fourth predetermined value, the standard size of the cargo based on the size of the cargo space of the vehicle and the standard weight of the cargo based on the loadable weight of the vehicle are set. It is preferable to set.

  The above-described first to fourth predetermined values affect the accuracy of the occurrence prediction of cargo collapse. The control device 10 of the present embodiment refers to the location information acquired from the position detection device 71 of the navigation device 70 and the load collapse occurrence history in which the load collapse occurrence history is associated, and the load collapse of the acquired current position. One or more predetermined values of the first predetermined value to the fourth predetermined value are changed according to the possibility of occurrence. This is because the load collapse is influenced not only by the movement on the vehicle side but also by the road characteristics at each point such as the road shape and road gradient.

  The load collapse occurrence history 312 of this embodiment is stored in the server 300, and the control device 10 refers to the load collapse occurrence history 312 of the server 300 via the communication devices 40 and 320. The load collapse occurrence history 312 stores the number and frequency (number of times / time) of occurrence of load collapse at each point. When the number or frequency of occurrences of load collapse is high, the control device 10 changes a predetermined value of one or more of the first predetermined value to the fourth predetermined value to be low and easily detects when the load collapse occurs. Like that. That is, at a point (road) where cargo collapse is likely to occur, the occurrence of cargo collapse is detected even if the longitudinal acceleration or lateral acceleration is lower than the normal set value. As a result, the occurrence of cargo collapse can be detected with high accuracy in consideration of the road characteristics for each point.

  Further, the control device 10 changes any one or more predetermined values from the first predetermined value to the fourth predetermined value according to the vehicle speed acquired from the vehicle. This is because the load collapse is not only influenced by the longitudinal acceleration or the lateral acceleration but also by the vehicle speed of the vehicle.

  The vehicle speed of this embodiment is acquired from the vehicle speed sensor 63 of the vehicle. When the vehicle speed is high, the control device 10 changes any one or more of the first predetermined value to the fourth predetermined value to a high value so that it can be easily detected when load collapse occurs. That is, in a scene where the vehicle is traveling at a relatively high speed, occurrence of load collapse is detected even if the longitudinal acceleration or the lateral acceleration is lower than the normal set value. On the other hand, load collapse is unlikely to occur when driving at an extremely low speed, so the longitudinal acceleration or lateral acceleration is set higher than the normal set value so that the occurrence of load collapse is not easily detected. Thereby, it is possible to detect the occurrence of cargo collapse with high accuracy in consideration of the traveling situation including the vehicle speed.

  Next, the output function will be described. The control apparatus 10 outputs the load collapse information regarding the load collapse including the captured image. Specifically, the controller 10 may include at least a captured image of the cargo as the cargo collapse information, and may include audio information reporting that the cargo collapse occurs. The control device 10 causes the display 31 to display a captured image of the cargo that has collapsed, and outputs audio information indicating that the cargo collapse has occurred or has occurred from the speaker 32.

  Next, the output control function will be described. The control apparatus 10 of this embodiment controls the timing which outputs cargo collapse information. The control device 10 causes the output device 30 to output the cargo collapse information at a predetermined timing after the timing when the occurrence of the cargo collapse trigger is detected. In the present embodiment, the occurrence timing of the load collapse trigger is distinguished from the timing at which the actual load collapse occurs, and the actual load collapse occurs based on the trigger occurrence timing after the occurrence timing of the load collapse trigger. The timing of the load collapse is determined, and the load collapse information is output at the timing when the load collapse actually occurs. Thereby, the captured image which shows the state of cargo collapse can be shown to a passenger | crew at the timing which cargo collapse actually occurs. There is a high possibility that actual cargo collapse has not occurred at the timing when the vehicle information changes temporarily. Even if the captured image of the cargo before the collapse of the cargo is shown, it is unnecessary for the occupant and only annoying. In the present embodiment, since the load collapse information is output at a timing at which an actual load collapse is predicted to occur, information useful for the occupant can be presented at an appropriate timing.

  Further, in the present embodiment, since a captured image is not used for determining the collapse of cargo, it is randomly arranged in the cargo compartment of the vehicle, and it is possible to detect the occurrence of cargo collapse of various shapes of cargo.

  The control device 10 according to the present embodiment determines the timing at which the longitudinal acceleration becomes zero for the first time after the occurrence timing of the detected load collapse trigger as the timing at which the load collapse actually occurs, and outputs the load collapse information at this timing. Let After the longitudinal acceleration is greater than or equal to the first predetermined value and the trigger of cargo collapse is confirmed, the timing at which the longitudinal acceleration changes such that the longitudinal acceleration becomes zero is detected as the timing at which the cargo collapse actually occurs. Since the collapse information is output, information useful for the occupant can be presented at an appropriate timing. In addition, since the configuration is such that cargo collapse information is presented to the occupant after the longitudinal acceleration becomes zero, it is prohibited to present the cargo collapse information to the occupant when the vehicle is suddenly starting or stopping. be able to. That is, presentation of cargo collapse information can be prohibited at the timing when the occupant should concentrate on vehicle operation.

  Similarly, the control device 10 according to the present embodiment determines the timing at which the lateral acceleration becomes zero for the first time after the occurrence timing of the detected load collapse trigger as the timing at which the load collapse actually occurs, and the load collapse occurs at this timing. Output information. After the lateral acceleration is equal to or greater than the second predetermined value and the trigger for the collapse of the load is confirmed, the timing at which the lateral acceleration changes such that the lateral acceleration becomes zero is detected as the timing at which the collapse of the load actually occurs. Since the collapse information is output, information useful for the occupant can be presented at an appropriate timing. In addition, since it is configured to present the cargo collapse information to the occupant after the lateral acceleration becomes zero, it is prohibited to present the cargo collapse information to the occupant when the vehicle is making a sudden turn operation or retreat operation. can do. That is, presentation of cargo collapse information can be prohibited at the timing when the occupant should concentrate on vehicle operation.

  In addition, the control device 10 according to the present embodiment, after the occurrence timing of the cargo collapse trigger detected based on the longitudinal acceleration, the timing at which the accelerator or brake operation of the vehicle acquired from the vehicle shifts to a predetermined steady state. Is determined as the timing at which the actual load collapse occurs, and the load collapse information is output at this timing. After the longitudinal acceleration is greater than or equal to the first predetermined value and the trigger of the cargo collapse is confirmed, the cargo collapse actually occurs at the timing when the longitudinal acceleration changes such that the operation of the accelerator or brake of the vehicle shifts to a predetermined steady state. Since it detects as timing and outputs cargo collapse information at this timing, information useful for the passenger can be presented at an appropriate timing. Furthermore, since it is configured so that the information on collapse of the vehicle is presented to the occupant after the operation of the accelerator or brake of the vehicle has shifted to a predetermined steady state, the information on the collapse of the vehicle when the vehicle is suddenly started or stopped, etc. Can be prohibited from being presented to passengers. That is, presentation of cargo collapse information can be prohibited at the timing when the occupant should concentrate on vehicle operation.

  Similarly, the control device 10 according to the present embodiment actually detects the timing at which the steering operation of the vehicle acquired from the vehicle shifts to a predetermined steady state after the occurrence timing of the load collapse trigger detected based on the lateral acceleration. Is determined as the timing at which the cargo collapse occurs, and the cargo collapse information is output at this timing. The timing at which the load collapse actually occurs when the lateral acceleration of the vehicle changes to the predetermined steady state after the lateral acceleration becomes equal to or greater than the second predetermined value and the trigger for the load collapse is confirmed. And information on the collapse of cargo is output at this timing, so that information useful for the passenger can be presented at an appropriate timing. Since the vehicle collapse operation has been configured to be presented to the occupant after the vehicle's steering operation has shifted to a predetermined steady state, the cargo collapse information is presented to the occupant when the vehicle is making a sudden turn or retreat operation. Can be prohibited. That is, presentation of cargo collapse information can be prohibited at the timing when the occupant should concentrate on vehicle operation.

  The control device 10 according to the present embodiment outputs load collapse information at a timing when a predetermined time has elapsed after the occurrence timing detected after the detected occurrence timing of the load collapse trigger. The control device 10 predicts that the cargo will move due to the external force applied to the cargo and the actual cargo collapse will occur after a predetermined time has elapsed since the longitudinal acceleration becomes equal to or greater than the first predetermined value and the trigger of the cargo collapse is confirmed. In addition, since the cargo collapse information is output, information useful for the occupant can be presented at an appropriate timing.

  Similarly, the control device 10 according to the present embodiment outputs the load collapse information at a timing when a predetermined time has elapsed after the occurrence timing detected after the detected occurrence timing of the load collapse trigger. The control device 10 predicts that the cargo will move due to the external force applied to the cargo after the predetermined time has elapsed since the lateral acceleration becomes equal to or greater than the second predetermined value and the trigger of the cargo collapse is confirmed, and the cargo collapse actually occurs. In addition, since the cargo collapse information is output, information useful for the occupant can be presented at an appropriate timing.

  The “predetermined time” from the occurrence of the trigger to the actual occurrence of cargo collapse is set according to the vehicle speed. Since the occurrence of cargo collapse is affected by the speed of the host vehicle, this is taken into account. Although not particularly limited, the “predetermined time” is set shorter as the vehicle speed of the host vehicle is higher. As the vehicle speed increases, a larger external force may be applied to the cargo. Therefore, the vehicle speed is set to be shorter than the “predetermined time” set during normal times. Further, since the situation changes in a shorter time as the vehicle speed is faster, the time is set shorter than the “predetermined time” set in the normal time. Thereby, it is possible to accurately determine the occurrence timing of the cargo collapse according to the actual situation of the vehicle and present the cargo collapse information at an appropriate timing.

  Further, the control device 10 according to the present embodiment detects the timing at which the longitudinal acceleration is equal to or greater than a third predetermined value that is greater than the first predetermined value as an emergency occurrence timing that is likely to cause cargo collapse. Causes the collapse information to be output immediately after the detected emergency occurrence timing. When an emergency occurrence timing that is highly likely to cause a load collapse is detected, the load collapse information is output immediately thereafter, so that the load collapse information can be presented to the occupant at an appropriate timing at which the load collapse occurs.

  Similarly, when the control device 10 according to the present embodiment detects a timing at which the lateral acceleration is equal to or greater than a fourth predetermined value that is greater than the second predetermined value as an emergency occurrence timing at which cargo collapse is likely to occur. In this case, cargo collapse information is output immediately after the detected emergency occurrence timing. When an emergency occurrence timing that is highly likely to cause a load collapse is detected, the load collapse information is output immediately thereafter, so that the load collapse information can be presented to the occupant at an appropriate timing at which the load collapse occurs.

  Finally, the storage function will be described. When the load collapse information is output, the control device 10 according to the present embodiment associates the location information from which the load collapse information is output with the occurrence history of the load collapse to associate the internal or external storage device 301 or the RAM 13. Is stored as a load collapse occurrence history. The timing at which the cargo collapse information is output can be evaluated as the timing at which the cargo collapse actually occurred, so by accumulating the cargo collapse occurrence history, it is possible to generate information on points or road characteristics where cargo collapse is likely to occur. it can. As described above, by referring to the load collapse occurrence history and correcting any one or more of the first predetermined value to the fourth predetermined value, the timing at which the load collapse actually occurs, that is, the load collapse information is obtained. A timing suitable for output can be derived. As a result, the cargo collapse information can be presented to the occupant at an appropriate timing when the cargo collapse occurs.

  Then, the procedure of the information provision process of the information provision system 1 for vehicles of this embodiment is demonstrated based on FIGS. 3-7 flowchart.

  As shown in FIG. 3, when the information providing process is started, first, in step S1, an initialization process for initializing timers, counters, and flags used for the subsequent processes is executed. This process is repeatedly performed at a predetermined cycle.

  Next, in step S2, the current vehicle state is acquired from the ignition via the longitudinal sensor 61, the lateral acceleration sensor 62, the position detection device (GPS) 71, the speed sensor 63, and the vehicle controller 50, which are vehicle information.

  In step S3, it is determined whether or not the vehicle is stopped based on the vehicle information acquired in step S2. Specifically, if the ignition information managed by the vehicle controller 50 is in an OFF state, the process is terminated, and if not, the process proceeds to step S4.

  In step S4, a predetermined value (threshold value) changing process used for detecting the occurrence of a load collapse trigger is performed. The predetermined value is changed as necessary, and the process proceeds to step S5.

  In step S5, a branch process based on the output value of the longitudinal acceleration acquired in step S2 is performed. If the output value of the longitudinal acceleration is greater than or equal to the first predetermined value (threshold value) set in step S4, the process proceeds to step S6, and if not, the process proceeds to step S7. In step S <b> 6, the control device 10 detects the timing at which the cargo collapse actually occurs based on the longitudinal acceleration, and determines the timing as the output timing of the cargo collapse information.

  Although not particularly limited, the control device 10 according to the present embodiment causes the load collapse information to be output at a timing when a predetermined time has elapsed after the occurrence timing of the trigger that causes the load collapse when the longitudinal acceleration equal to or greater than the first predetermined value is detected. . For this predetermined time, a default value can be set in advance based on the size, weight, driving / braking characteristics, and the like of the vehicle.

  In step S7, a branching process based on the lateral acceleration output value obtained in step S2 is performed. If the output value of the lateral acceleration is greater than or equal to the second predetermined value (threshold value) set in step S4, the process proceeds to step S8, and if not, the process proceeds to step S9. In step S <b> 9, the control device 10 detects a timing at which the load collapse actually occurs based on the lateral acceleration, and determines the timing as an output timing of the load collapse information.

  Although not particularly limited, the control device 10 according to the present embodiment outputs the cargo collapse information at a timing when a predetermined time has elapsed after the occurrence timing of the trigger causing the cargo collapse when the lateral acceleration of the second predetermined value or more is detected. . For this predetermined time, a default value can be set in advance based on the size, weight, steering characteristics, and the like of the vehicle.

  In step S9, if the output timing is determined whether it is the output timing determined in step S6 or step S8, the process proceeds to step S10, and if there is no output timing, the process returns to S2 to repeat the process. In step S10, cargo collapse information is output. Specifically, a captured image in the cargo compartment of the vehicle captured by the camera 20 is displayed on the display 31. The display of cargo collapse information is limited within a predetermined time. That is, the display process ends when a predetermined time has elapsed after the display of the cargo collapse information is started. This is to prevent the passenger from gazing at the information on the collapse of the cargo. When the long-time display process is completed, the process returns to step S2 to repeat the process.

  Based on FIG. 4, the process of changing the predetermined value serving as the threshold value in step S4 of FIG. 3 will be described. The control device 10 refers to the load collapse occurrence history in which the location information and the load collapse occurrence history are associated with each other, and the first predetermined value to the fourth predetermined value according to the possibility of occurrence of load collapse at the acquired current position. Any one or more predetermined values are changed. Or the control apparatus 10 changes any one or more predetermined values of the 1st predetermined value thru | or 4th predetermined value according to the vehicle speed of the said vehicle acquired from the vehicle. Of course, the control device 10 can also accept driver input by operating a switch that functions as an interface of the navigation device 70.

  Specifically, in step S401 in FIG. 4, the predetermined value is changed according to the selection condition input by the user. The occupant selects and inputs an arbitrary stage from the options such as low, medium, and high according to the level of a predetermined value on the switch provided in the navigation device 70. The control device 10 selects a predetermined value (threshold value) to be used for the information providing process according to the occupant input.

  In step S402, a threshold value (predetermined value) is changed according to the speed of the host vehicle. When the input of the speed sensor 63 is equal to or less than a predetermined speed (for example, 5 km / h), the control device 10 sets a predetermined value that is several times (for example, three times) a default predetermined value (threshold value) set at the normal time. It is set as a predetermined value (threshold value) used for this processing. When the input of the speed sensor 63 is larger than a predetermined speed (for example, 5 km / h), the default predetermined value (threshold value) set at the normal time is set as the predetermined value (threshold value) used for this processing as it is.

  In step S403, the threshold value is changed according to the spot information where the vehicle travels. The control device 10 refers to the load collapse occurrence history 312 that associates the location information stored in the server 300 with the load collapse occurrence history, and loads the load at the location corresponding to the location information of the current position acquired from the position detection device 71. Determine the occurrence history of collapse. When it is determined that load collapse has occurred at the travel point or that there is a high possibility that load collapse will occur, the default predetermined value (threshold value) set at the normal time is changed to a low value. In addition, when it is determined that load collapse has occurred at the travel point or that there is a high possibility of load collapse, the control device 10 reaches the level of the predetermined value (threshold value) designated in step S401. The corresponding option is changed one step lower, and the lower predetermined value (threshold value) is set for use in the current or next processing.

  Steps S401 to S403 described above may be combined to change the predetermined value, or the predetermined value may be changed by any one process.

If the longitudinal acceleration is less than the first predetermined value, the process returns to step S601. If the longitudinal acceleration is equal to or greater than the first predetermined value, the process proceeds to step S603. Then, the control device 10 waits for a timing when the longitudinal acceleration becomes zero for the first time. The timing at which the longitudinal acceleration becomes zero for the first time in step S603 is determined to be the timing at which the actual cargo collapse actually occurs, and the process proceeds to step S604. In step S604, it is determined that the timing at which the actual cargo collapse occurs is the timing at which the cargo collapse information is output, and this determination is retained and the process is terminated.

If the lateral acceleration is less than the second predetermined value, the process returns to step S801, and if the lateral acceleration is equal to or greater than the second predetermined value, the process proceeds to step S803. Then, the control device 10 waits for a timing at which the lateral acceleration becomes zero for the first time. The timing at which the lateral acceleration becomes zero for the first time in step S803 is determined to be the timing at which the cargo collapse actually occurs, and the process proceeds to step S804. In step S804, it is determined that the timing at which the actual cargo collapse occurs is the timing at which the cargo collapse information is output, and this determination is retained and the process is terminated.

In step S1103, it is determined whether or not the acquired longitudinal acceleration is higher than a first predetermined value and is greater than or equal to a third predetermined value that is highly likely to cause cargo collapse. If the longitudinal acceleration is greater than or equal to the third predetermined value, the process proceeds to step S1105. In step S1105, the timing at which the longitudinal acceleration becomes equal to or greater than the third predetermined value is determined to be the emergency occurrence timing at which cargo collapse occurs immediately. In step S1105, it is determined that the timing at which the load collapse occurs is the timing at which the load collapse information is output, and this determination is retained and the process is terminated. If the longitudinal acceleration is less than the third predetermined value, the process proceeds to step S1105 after a predetermined time has elapsed in step S1104.

In step S1205, it is determined that the timing at which the lateral acceleration becomes equal to or greater than the fourth predetermined value is the emergency occurrence timing at which cargo collapse occurs immediately. In step S1205, it is determined that the timing at which this load collapse occurs is the timing at which the load collapse information is output, and this determination is retained and the process is terminated. If the lateral acceleration is less than the fourth predetermined value, the process proceeds to step S1205 after a predetermined time has elapsed in step S1204.

And the process proceeds to step S1304. In step S1304, the process branches based on the difference value calculated in step S1303. When the accelerator operation or the brake operation of the vehicle shifts to a predetermined steady state, the control device 10 of the present embodiment proceeds to step S1306, otherwise proceeds to step S1305. Specifically, if the difference values of the accelerator opening (stepping amount) and the brake opening (stepping amount) calculated in step S1303 are both 0, the control device 10 proceeds to step S1306, otherwise. In that case, the process proceeds to step S1305.

  The vehicle information providing apparatus 100 according to the present embodiment has the following effects.

  [1] The vehicular information provision apparatus 100 according to the present embodiment distinguishes the occurrence timing of a load collapse trigger from the timing at which an actual load collapse occurs, and generates the trigger after the occurrence timing of the load collapse trigger. Based on the timing, the timing at which actual load collapse occurs is determined, and the load collapse information is output at the timing at which the load collapse actually occurs. Thereby, since the captured image which shows the state of cargo collapse can be shown to a passenger | crew at the timing when cargo collapse actually occurs, information useful for a passenger | crew can be shown at a suitable timing.

  [2] The vehicular information providing apparatus 100 according to the present embodiment detects the timing at which the longitudinal acceleration has changed such that the longitudinal acceleration becomes zero after the longitudinal acceleration is equal to or greater than the first predetermined value and the trigger of the cargo collapse is confirmed. Since it is detected as a timing at which cargo collapse actually occurs and cargo collapse information is output at this timing, information useful for the occupant can be presented at an appropriate timing. In addition, since the configuration is such that cargo collapse information is presented to the occupant after the longitudinal acceleration becomes zero, it is prohibited to present the cargo collapse information to the occupant when the vehicle is suddenly starting or stopping. be able to. That is, presentation of cargo collapse information can be prohibited at the timing when the occupant should concentrate on vehicle operation.

  [3] The vehicle information providing apparatus 100 according to the present embodiment detects the timing at which the lateral acceleration changes to zero when the lateral acceleration becomes zero after the lateral acceleration is equal to or greater than the second predetermined value and the trigger of the cargo collapse is confirmed. Since it is detected as a timing at which cargo collapse actually occurs and cargo collapse information is output at this timing, information useful for the occupant can be presented at an appropriate timing. In addition, since it is configured to present the cargo collapse information to the occupant after the lateral acceleration becomes zero, it is prohibited to present the cargo collapse information to the occupant when the vehicle is making a sudden turn operation or retreat operation. can do. That is, presentation of cargo collapse information can be prohibited at the timing when the occupant should concentrate on vehicle operation.

  [4] In the vehicle information providing apparatus 100 according to the present embodiment, the cargo is moved by the external force applied to the cargo after a predetermined time has elapsed since the longitudinal acceleration is equal to or greater than the first predetermined value and the trigger for the collapse of the cargo is confirmed. Since cargo collapse information is output by predicting the actual occurrence of cargo collapse, information useful for the occupant can be presented at an appropriate timing.

  [5] In the vehicle information providing apparatus 100 according to the present embodiment, the cargo is moved by an external force applied to the cargo after a predetermined time has elapsed since the lateral acceleration is equal to or greater than the second predetermined value and the trigger for the collapse of the cargo is confirmed. Since cargo collapse information is output by predicting the actual occurrence of cargo collapse, information useful for the occupant can be presented at an appropriate timing.

  [6] The vehicle information providing apparatus 100 according to the present embodiment sets the “predetermined time” from the occurrence of the trigger to the actual occurrence of cargo collapse according to the vehicle speed. Thereby, it is possible to accurately determine the occurrence timing of the cargo collapse according to the actual situation of the vehicle and present the cargo collapse information at an appropriate timing according to the traveling status of the vehicle.

  [7] In the vehicle information providing apparatus 100 according to the present embodiment, the accelerator or brake operation of the vehicle acquired from the vehicle is in a predetermined steady state after the occurrence timing of the load collapse trigger detected based on the longitudinal acceleration. Is determined as the timing at which cargo collapse actually occurs, and cargo collapse information is output at this timing. The timing at which load collapse actually occurs when the longitudinal acceleration changes after the acceleration or brake operation of the vehicle is in a predetermined steady state after the longitudinal acceleration is greater than or equal to the first predetermined value and the trigger for the load collapse is confirmed. And information on the collapse of cargo is output at this timing, so that information useful for the passenger can be presented at an appropriate timing.

  [8] In the vehicle information providing apparatus 100 according to the present embodiment, the steering operation of the vehicle acquired from the vehicle shifts to a predetermined steady state after the occurrence timing of the load collapse trigger detected based on the lateral acceleration. The timing is determined as the timing at which the cargo collapse actually occurs, and the cargo collapse information is output at this timing. After the lateral acceleration becomes equal to or greater than the second predetermined value and the trigger for the collapse of the cargo is confirmed, the collapse of the vehicle actually occurs at the timing at which the lateral acceleration received by the vehicle changes to the predetermined steady state. Since it detects as timing and outputs cargo collapse information at this timing, information useful for the passenger can be presented at an appropriate timing.

  [9] The vehicular information provision apparatus 100 according to the present embodiment sets the timing at which the longitudinal acceleration is equal to or greater than a third predetermined value greater than the first predetermined value as an emergency occurrence timing at which cargo collapse is highly likely to occur. If detected, the cargo collapse information is output immediately after the detected emergency occurrence timing. When an emergency occurrence timing that is highly likely to cause a load collapse is detected, the load collapse information is output immediately thereafter, so that the load collapse information can be presented to the occupant at an appropriate timing at which the load collapse occurs.

  [10] The vehicle information providing apparatus 100 according to the present embodiment sets the timing at which the lateral acceleration is equal to or higher than the fourth predetermined value, which is larger than the second predetermined value, as the emergency occurrence timing at which the cargo collapse is likely to occur. If detected, the cargo collapse information is output immediately after the detected emergency occurrence timing. When an emergency occurrence timing that is highly likely to cause a load collapse is detected, the load collapse information is output immediately thereafter, so that the load collapse information can be presented to the occupant at an appropriate timing at which the load collapse occurs.

  [11] The vehicle information providing apparatus 100 according to the present embodiment changes a predetermined value of one or more of the first predetermined value to the fourth predetermined value to be low when the number or frequency of occurrence of cargo collapse is high. However, it should be easy to detect when cargo collapse occurs. That is, at a point (road) where cargo collapse is likely to occur, the occurrence of cargo collapse is detected even if the longitudinal acceleration or lateral acceleration is lower than the normal set value. As a result, the occurrence of cargo collapse can be detected with high accuracy in consideration of the road characteristics for each point.

  [12] When the vehicle speed is high, the vehicle information providing apparatus 100 according to the present embodiment changes any one or more of the first predetermined value to the fourth predetermined value to a high value, and a load collapse occurs. Make it easy to detect. That is, in a scene where the vehicle is traveling at a relatively high speed, occurrence of load collapse is detected even if the longitudinal acceleration or the lateral acceleration is lower than the normal set value. On the other hand, load collapse is unlikely to occur when driving at an extremely low speed, so the longitudinal acceleration or lateral acceleration is set higher than the normal set value so that the occurrence of load collapse is not easily detected. Thereby, it is possible to detect the occurrence of cargo collapse with high accuracy in consideration of the traveling state such as the vehicle speed.

  [13] When the vehicle collapse information is output, the vehicle information providing apparatus 100 according to the present embodiment generates the load collapse by associating the location information from which the load collapse information is output with the occurrence history of the load collapse. Store as history. The timing at which the cargo collapse information is output can be evaluated as the timing at which the cargo collapse actually occurred, so by accumulating the cargo collapse occurrence history, it is possible to generate information on points or road characteristics where cargo collapse is likely to occur. it can. As a result, the cargo collapse information can be presented to the occupant at an appropriate timing when the cargo collapse occurs.
