Hereinafter, a warning information notification system of each form will be described using the drawings. In the drawings, the same reference numerals are given to the same components, and the description will be omitted. Further, each component in each embodiment may be arbitrarily combined within the range where there is no contradiction.

(An example of the form that can be taken by the alert information notification system)
The following describes one possible example of the caution information notification system.

1. Caution information notified by the caution information notification system and its judgment When driving a car, there are situations where it can be dealt with if the driver can know in advance, such as feeling inconvenient, feeling uncomfortable, or having an accident risk. If such a driver can know the caution zone to be driven with caution, the driver can drive the vehicle comfortably and safely. In order to improve the driver's comfort and safety, the caution information notification system 1 notifies the driver of caution information on the road. Attention information said here means traffic jam, accident, on-street parking, freezing, wet, snowfall, bad road, bad spot on road, point where children etc. are often out, point where accident happens, fog frequently point, slip occurrence point Etc. represents information on where the driver should drive with caution.

  In the caution information notification system 1, it is possible to detect the pedaling force of the driver directly, and to accurately determine the preparatory action of stepping on the driver's brake, the manner of stepping on the brake such as slow driving or sudden braking, and the urgency of the braking action. Moreover, it can utilize as big data by collecting, accumulate | storing and analyzing the treading force information of the several vehicle 2 provided with the caution information notification system 1. FIG. The treading force information acquired from the vehicle 2 is collected and accumulated, and the caution information is determined from the information of one or more vehicles.

  In the following description, the driver who is driving the vehicle 2 when the caution information notification system 1 acquires pedal force information, and the user who is driving the vehicle 2 who acquires caution information from the caution information notification system 1 Explain as.

  When the driver suddenly brakes, which point happened to the driver's unexpected event such as an accident or a child's jumping out, or an event caused by the weather such as freezing, wetting, or fog occurred? It is likely to be It is possible to improve the safety of the user by notifying the user of the caution information so as to travel with caution based on such caution information. Further, at this time, the warning information may be determined in more detail. Hereinafter, a method of determining detailed attention information will be described by way of an example.

  If there is only one car on which the sudden braking has been applied, or if there are several cars in succession in a short time at the same place, it may be judged as a sudden accident. At this time, for example, the user may be notified that there is a possibility of an accident and safe driving is performed, such as “Please drive with caution because an accident may have occurred”. In this way, the user can be careful and drive to avoid the further induction of the accident to improve the safety, or the user can search the detour to improve the driver's comfort. The user or the user of the caution information notification system 1 can appropriately select the time and the number of vehicles for judging the accident.

  If there are multiple cars on the same spot for a long time in the same place, or if the car on which the fast brake is applied is slowing after that, brakes are applied cyclically several times to avoid locking the tires. In the case of stepping on, when the brake is depressed for a certain period in order to operate the ABS, it may be determined that there is a change in the road condition caused by the weather such as freezing, slipping and fog. In addition, if the driver always puts a foot on the brake pedal after pressing the brake suddenly, it may be determined that the road is frozen and very dangerous. At this time, the user's safety can be improved by notifying the user of a caution, such as "Please drive with caution because the road surface condition is changing".

  There is no car that brakes in a row continuously, but if there is a car with a gap in the same place and brakes appear, it is a dangerous place where that place is easy to brake suddenly, such as a place with lots of children jumping out. Determine that there is. In this case, it is possible to improve the safety of the user by notifying the user of a notice such as "A sudden braking occurrence point, please drive with caution" to the user.

  There is no car that brakes on the brakes in succession, but a car that brakes on the brakes appears in the same place at intervals, and when there is no periodicity in the timing to brake the brakes, a large tree or a block that blocks the traveling direction It is determined that the road is a dangerous place where it is easy to apply a sudden brake such as a road with a poor visibility such as a signboard or a continuous curve. In this case, it is possible to improve the safety of the user by notifying the user of a notice such as "A sudden braking occurrence point, please drive with caution" to the user.

  When the driver is driving slowly, it may be determined that there is a change in the road condition due to a road congestion, a bad road, freezing, wetting, fog or the like. A place where the vehicle 2 starts traveling slowly deviates to the near side of the traveling direction of the vehicle 2 with time, and when the traveling distance is long, it may be determined as traffic jam. In this case, the user's safety can be provided by notifying the user of a warning such as "Congestion is occurring" or "Please drive with caution because the road surface condition is changing." Can be improved. In addition, if the user can know the warning information in advance, the comfort of the user can be improved by searching for the detour.

  When the driver puts his / her foot on the brake pedal and is driving with the brake on at any time, it can be determined that the vehicle is in a dangerous state of freezing. In this case, the user's safety can be improved by notifying the user of a caution, such as "the road surface is frozen, please drive with caution." In addition, if the user can know the warning information in advance, the comfort of the user can be improved by searching for the detour.

2. Configuration of Attention Information Notification System An example of a configuration that can be taken by the attention information notification system is shown below.

  FIG. 1 is a diagram showing the configuration of an example of a possible form of the caution information notification system, and FIG. 2 is a diagram showing the relationship between vehicles of the caution information notification system and an information center.

  The caution information notification system 1 includes a vehicle 2 and an information center 3 that communicates information with the vehicle 2.

  First, the configuration of the vehicle 2 will be described.

  The vehicle 2 travels the road by the operation of a driver or a user, and the pedaling force detecting means 4 mounted on the brake pedal, and the position information acquiring means 5 for acquiring the position information at which the pedaling force detecting means 4 is operated; It has communication means 6 for communicating the depression force information of the brake pedal detected by the depression force detection means 4 with the information center 3 and notification means 7 for notifying the user of the caution information of the road.

The pedaling force detecting means 4 detects the pedaling force generated on the brake pedal by the driver stepping on the brake pedal. The brake pedal unit generally includes a plate that a driver steps on, a pedal arm that supports the plate and transmits the pedaling force of the driver, and a clevis and clevis pin that supports the pedal arm and transmits the pedal arm to the rod via the pedaling force. It comprises a master cylinder that pumps brake fluid to the wheel cylinder, a simulator that generates a reaction force according to the operation of the brake pedal, and a rod that transmits the stepping force to the master cylinder. As the pedaling force detecting means 4, a strain gauge or a strain resistance element may be provided on any of a plate, a pedal arm, a clevis and clevis pin, a rod, a master cylinder and a simulator. Alternatively, a strain gauge or strain resistance element may be provided on the strain generating body, and a strain gauge or strain resistance element may be provided on the plate, pedal arm, clevis / clevis pin, rod, master cylinder, or simulator. As described above, the depression force detection means 4 only needs to be able to detect the distortion generated in the members constituting the brake pedal, and detection means other than the strain gauges and strain resistance elements may be employed. The treading force detection means 4 has better responsiveness and detection sensitivity to changes in the treading force than when using a stroke sensor or a hydraulic pressure sensor to directly detect distortion generated in the brake pedal, and further after the driver has stepped on the brake pedal The applied treading force can be detected. In this way, the sudden braking can be detected with high accuracy when the sudden braking is stepped on. Further, since the pedaling force detecting means 4 can detect the pedaling force from the range of the play of the brake pedal, it can also detect that the driver lightly put his or her foot on the brake pedal. Thus, when the driver depresses the brake pedal, the depressing force can be detected from the preparatory movement of the driver, so that the depressing force can be detected more quickly than the stroke sensor or the hydraulic pressure sensor.

  The position information acquisition unit 5 acquires position information of the vehicle 2 from outputs of a GPS (Global Positioning System) measurement unit, a distance sensor (not shown), and an azimuth sensor (not shown) provided in the vehicle 2. Whether to use all of the GPS measurement unit, the distance sensor, and the direction sensor as the position information acquisition means 5, or to use only some of them, or to use them in combination can be selected as necessary. The position information acquisition means 5 acquires the position information at which the pedaling force detection means 4 has operated, and transmits it to the information center 3. By the position information acquisition means 5 acquiring the position information, it is possible to acquire information on where and how the driver stepped on the brake. In this way, it is possible to obtain information on the place where the caution information occurs.

  The communication unit 6 communicates with the treading force detection unit 4, the position information acquisition unit 5, the notification unit 7, and the information center 3. The communication means 6, the treading force detection means 4 and the position information acquisition means 5 communicate by wire or wirelessly. The communication means 6 and the notification means 7 communicate by wire or wirelessly. The communication means 6 and the information center 3 communicate wirelessly. The communication means 6 between the communication means 6 and the information center 3 may be a mobile phone network, a wireless LAN (Local Area Network) such as Wi-Fi, VICS (registered trademark) (Vehicle Information and Communication System), inter-vehicle communication A system (CVSS: Connected Vehicles Suport System), communication systems, such as LTE / 3G of a mobile etc., etc. are employable. It can be appropriately selected according to the use environment of the caution information notification system 1 or the like. The communication means 6 transmits the pedaling force information detected by the pedaling force detecting means 4 to the information center 3, and transmits the caution information received from the information center 3 to the notifying means 7. Further, the position information at which the pedaling force detecting means 4 acquired at this time and acquired by the position information acquiring means 5 is also transmitted to the information center 3 at the same time. Although two notification means 7 are provided to communicate with both the pedaling force detecting means 4 and the notifying means 7, the communication means 6 for transmitting pedaling force information to the information center 3 and the caution information are transmitted to the notifying means 7 The communication means 6 may have another configuration. The communication between the communication means 6 and the information center 3 may be performed constantly, but the communication may be performed only when the wireless LAN such as Wi-Fi is available. If the communication means 6 constantly communicates, the user can always obtain the latest information, and if communication is performed only when a wireless LAN such as Wi-Fi is available, energy saving can be achieved. The timing of communication can be appropriately selected depending on the use environment of the caution information notification system 1 or the like, and may be set by the user.

  An in-vehicle terminal device such as a car navigation device mounted on the vehicle 2 is used as the notification unit 7. The caution information received from the information center 3 via the communication means 6 is displayed on the on-vehicle terminal device to notify the user. As a method of notifying the user of the in-vehicle terminal device, warning information is displayed on the map displayed on the in-vehicle terminal device, or "the traffic jam is 1 km ahead" or "the road surface is frozen 500 m ahead" by voice. It may be notified like. In the case of notifying by voice only, not the on-vehicle terminal but only the speaker may be adopted as the notifying means 7. In addition to notifying users of road warning information, for example, "Please install a chain because it snows 10 km ahead," or "200 m ahead, it is a point where accidents occur frequently, and run with caution. You may call on the user to drive with caution. Furthermore, a detour may be retrieved and presented to the user in front of a place where traveling such as traffic congestion or freezing takes time. The notification means 7 can notify the user of the caution information to urge the user to drive safely.

  The other structure with which the vehicle 2 is provided is demonstrated below. Although the caution information notification system 1 operates with the above configuration, the determination accuracy of the caution information is improved if the following configuration is further provided.

  The time acquisition means 8 which detects the time when the depression force detection means 4 operated is provided. The time acquisition means 8 uses a clock built in the notification means 7. However, the time acquisition means 8 is not limited to the clock incorporated in the notification means 7, and a clock for the time acquisition means 8 may be provided separately from the notification means 7. The time acquisition means 8 transmits the time information at which the pedaling force detection means 4 operated to the information center 3 via the communication means 6. The transmission of the time information by the time acquisition means 8 is the same as the timing when the depression force detection means 4 transmits the depression force information to the information center 3. As a result, the driver has applied what kind of brake in which season, what kind of brake applied in what month, what kind of brake applied on what day of the week, what kind of brake applied at what time You can get information that you say. This makes it possible to acquire the trend of the season, month, day of the week, and time when the caution information occurs. By obtaining this information, the time such as "a place to drive with particular caution for freezing winters" and "a place for people to drive with particular possibility for people to fly out on weekday evenings" etc. The linked attention information can be obtained and notified.

  An outside air temperature detecting means 9 for detecting the outside air temperature of the vehicle 2 is provided. A temperature sensor is used as the outside air temperature detection means 9. The outside air temperature detection means 9 detects the outside air temperature of the vehicle 2, and when the pedaling force detection means 4 transmits the pedaling force information to the information center 3, it transmits the outside air temperature information together. When the information center 3 determines the caution information using the outside air temperature information of the vehicle 2, it can be determined with high accuracy whether the road surface is frozen.

  A humidity detection means 10 for detecting the humidity outside the vehicle is provided. A humidity sensor is used as the humidity detection means 10. The humidity detecting means 10 detects the humidity outside the vehicle 2 and transmits the humidity information together when the pedaling force detecting means 4 transmits the pedaling force information to the information center 3. When the information center 3 determines the caution information using the humidity information outside the vehicle, it can be determined with high accuracy whether fog is generated.

  A wiper operation detection means 11 for detecting the operation of the wiper of the vehicle 2 is provided. The wiper operation detection unit 11 detects operation information of the wiper, and transmits the operation information of the wiper together when the depression force detection unit 4 transmits the depression force information to the information center 3. When the information center 3 determines the caution information using the operation information of the wiper, it can be determined with high accuracy whether the road surface is wet and slippery.

A steering operation detecting means 12 for detecting a steering angle of steering and a steering amount is provided. A steering angle sensor is used for the steering operation detection means 12. If the steering angle and steering amount of the steering are detected, the present invention is not limited to the steering angle sensor, and a torque sensor or the like may be used. The steering operation detection means 12 detects steering operation information, and when the pedaling force detecting means 4 transmits pedaling force information to the information center 3, it transmits steering operation information together. When the information center 3 determines the caution information using the steering operation information, it can be determined with high accuracy that an obstacle such as a car parked on the road has been avoided.

  The outdoor camera 13 is provided to capture an image of the outside of the vehicle 2. The outdoor camera 13 photographs the outside of the vehicle, and when the pedaling force detecting means 4 transmits the pedaling force information to the information center 3, it transmits the vehicle outdoor information together. As a result, it is possible to obtain information on the outside of the vehicle such as road surface freezing, bad roads, traffic congestion, etc., so that the accuracy in determining the warning information of the information center 3 is improved. By combining the pedaling force detecting means 4 and the camera, the determination accuracy of the caution information is improved as compared with the case where only one of them is used. A drive recorder may be used as the camera 13 outside the vehicle.

  Next, the configuration of the information center 3 will be described.

  The information center 3 includes a communication unit 15 that communicates with the communication unit 6 of the vehicle 2 and a caution information determination unit 14 that determines caution information based on the information acquired from the vehicle 2.

  The caution information determination unit 14 determines caution information based on the information acquired from the vehicle 2. The caution information determination unit 14 has a server (not shown) that stores information acquired from the vehicle 2 and a determination unit (not shown) that determines caution information from the information stored in the server. The determination unit is hardware having a software program. The determination unit may be a program execution unit such as a CPU or processor that reads and executes a software program stored in a storage medium such as a hard disk or a memory. The caution information determination unit 14 may have a configuration in which the server and the determination unit are integrated without being divided into the configuration of the server and the determination unit.

  The communication unit 15 is in wireless communication with the communication means 6 of the vehicle 2. The communication unit 15 receives, from the communication unit 6, the pedal pressure information, the position information, the time information, the outside air temperature information, the humidity information, the wiper operation information, the steering operation information, and the camera image. These pieces of information are transmitted to the caution information determination unit 14. Further, the communication unit 15 transmits the attention information determined by the attention information determination unit 14 to the communication unit 6.

  The information center 3 may further include a weather information acquisition unit 16. The weather information acquisition unit 16 acquires information of the weather forecast. The weather forecast may be, for example, a weather forecast on the Internet. The weather information acquisition unit 16 transmits the weather information acquired from the weather forecast to the caution information determination unit 14. When the caution information determination unit 14 determines the caution information using the weather information, it is possible to determine with high accuracy the caution information caused by the weather such as freezing, fog, or slip.

3. Notification and Use of Caution Information to Users The provision of caution information to users of the caution information notification system will be described. FIG. 2 is a diagram showing a notification flow of caution information.

  The caution information notification system 1 starts and detects a pedal effort in S1.

  When the pedal effort is detected by the pedal effort detecting means 4, it is determined in S2 whether the pedal effort is unique. The unique pedaling force referred to here indicates a braking operation which is not performed in normal driving, such as sudden braking, slow driving, and preparatory movement of the driver. If the pedaling force is a unique pedaling force, the process proceeds to step S3. If the pedaling force is not a unique pedaling force, the process returns to the pedaling force detection again.

  In S3, information on various means provided in the vehicle 2 of the caution information notification system 1 is transmitted to the information center 3 together with the pedaling force information.

  In S4, the warning information determination unit 14 determines whether the pedaling force information is warning information. At this time, if the information center 3 includes the weather information acquisition unit 16, the weather information and the pedaling force information are combined and determined. When the caution information determination unit 14 determines that the warning information is not the warning information, the process returns to the detection of the pedal effort.

  In S5, the communication unit 15 of the information center 3 transmits the alert information to the notification unit 7 via the communication unit 6.

  At S6, based on the alert information received from the information center 3, the alert information is notified to the user using the alert information notification system 1. At this time, the warning information is notified only to the user of the vehicle 2 who is trying to drive the section to be driven with caution based on the information of the car navigation system, etc. Can notify the alert information only to the user who needs the alert information. This prevents the user from being distracted by the extra attention information or frustrated by the extra attention information because the user does not receive the extra attention information. Improves user comfort by receiving only the necessary attention information.

  After notifying the user of the caution information, the notice of the caution information by the caution information notification system 1 is ended. At this time, the caution information notification system 1 may be ended or may be returned to the start. Attention information may be notified only once or may be always notified. In the case of performing notification only by voice, the user does not feel bothered if it is a one-time notification, and if it is a notification of caution information on a map, it is better for the user to keep notifying constantly .

  Next, the acquisition timing of the caution information of the notification means 7 of the vehicle 2 will be described. Communication means 6 of the caution information notification system 1 periodically acquires caution information from the information center 3. The caution information from the information center 3 may be constantly received, or may be received only at a determined timing.

  In the case where attention information is constantly received, the communication means 6 and the communication unit 15 always communicate while the attention information notification system 1 is activated, and the user can always obtain the latest information. In addition, communication may be performed at all times, and communication may be performed only when there is a change in traffic conditions. In this way, the latest information can be acquired with the minimum communication.

  In the case where attention information is received only at a determined timing, for example, the attention information may be periodically received on a predetermined day such as the first day of every month, or a place where a wireless LAN such as Wi-Fi can be used Attention information may be received only when you come to In this case, since it is not necessary to always communicate, energy saving can be achieved. Moreover, when communicating using Wi-Fi etc., since it is easy to transmit a lot of data, it is suitable especially when acquiring a large amount of data.

  Note that the timing at which the communication means 6 acquires the caution information may be a combination of constant communication and periodic communication according to the caution information. For example, large attention information that changes with time, such as traffic congestion and street parking, is always communicated, and changes due to seasons such as small attention information or freezing that changes with time, such as a place with a lot of children jumping out Attention information to be sent may be communicated regularly and acquired. By changing the communication timing according to the content of the caution information, it becomes easier to balance energy saving and user's comfort.

  Also, the manner of communication may be set individually by the user. Thereby, the power consumption and the acquisition timing of information can be determined by the preference of the user.

  As described above, although the case where the user of the vehicle 2 passively receives the caution information has been described, a manager of the information center 3 or a user who is not driving the vehicle 2 acquires the caution information from the information center 3 It may be possible to By acquiring the caution information directly from the information center 3, a general user can make a travel plan before leaving the house, which improves the convenience of the user. If it is the manager of the information center 3, for example, if the manager of the information center 3 is a business operator such as a transportation business, it is possible to make a transportation plan using the caution information, so the work efficiency can be improved. Can be

  Further, in the above description, the case where the user acquires the caution information from the information center 3 has been described, but it is possible to directly acquire information acquired from the vehicle 2 such as treading force information and position information before being determined as caution information. It is good. Since the depression force detection means 4 can also detect the depression force applied after the brake pedal is completely depressed, a mat or can can be caught in the brake pedal to depress the brake by using it together with a sensor such as a stroke sensor which detects the stroke of the brake pedal. There is no situation that can be detected. Thereby, after the vehicle 2 causes an accident, it can be used as confirmation and evidence of the accident situation.

  In the following description, each embodiment of the caution information notification system will be described. However, for convenience of explanation, the vehicle acquiring the pedal effort information and the vehicle notifying the caution information are illustrated as the same one, but this vehicle is different It may be

Embodiment 1
The attention information notification system according to the first embodiment will be described below with reference to the drawings.

  FIG. 4 is a diagram showing the configuration of the caution information notification system of the first embodiment.

  As shown in FIG. 5, the caution information notification system 21 includes a vehicle 2 and an information center 3. Notification means for notifying the vehicle 2 of the pedaling force detecting means 4, position information acquiring means 5 for acquiring position information of the vehicle 2, communication means 6 for communicating pedaling force information and position information, and attention information acquired from the communication means 6 7 and have. The information center 3 includes a caution information determination unit 14 that determines caution information based on treading force information and position information, and a communication unit 15 that communicates with the communication unit 6.

  The caution information notification system 21 acquires detailed treading force information by the treading force detecting means 4, associates the positional information acquired by the positional information acquiring means 5 with the treading force information, and transmits the treading force information and the positional information to the information center 3. be able to. In this way, it is possible to determine traffic jams on roads, accidents, freezing, bad roads, sudden braking frequent points where sudden braking is easy to take, changes in road conditions due to weather, and the like.

  By notifying the user of the caution information by the notification means 7, the user can be urged to drive safely or the user can search for a detour. In addition, when the person who travels by detour travels to the destination earlier, the notification means 7 may automatically search for the detour and notify the user of the detour. Thereby, the user can drive the vehicle 2 safely and comfortably.

Second Embodiment
The alert information notification system according to the second embodiment will be described below with reference to the drawings.

  FIG. 5 is a diagram showing the configuration of a caution information notification system according to a second embodiment.

  As shown in FIG. 5, the caution information notification system 31 includes a vehicle 2 and an information center 3. The vehicle 2 has a treading force detecting means 4, a position information acquiring means 5 for obtaining position information of the vehicle 2, an outside air temperature detecting means 9 for detecting the outside air temperature of the vehicle 2, and an outside camera 13 for photographing the outside of the car And communication means 6 for communicating treading force information, position information, outside air temperature information and vehicle exterior information, and notification means 7 for notifying attention information acquired from the communication means 6. The information center 3 includes a caution information determination unit 14 that determines caution information based on treading force information and position information, and a communication unit 15 that communicates with the communication unit 6.

  Since the caution information notification system 31 can acquire outside temperature information, it can determine the condition of the road more accurately. Generally, the road surface may freeze when the outside temperature is 3 ° C. or less. Therefore, when the outside air temperature acquired by the outside air temperature detection unit 9 is 3 ° C. or less, it is determined that the road surface is frozen. When it is determined that the road is frozen, the user is notified of caution information. As a result, if the user drives with caution, the user's safety can be improved, and if the user searches for a detour, the user's safety and comfort can be improved. In addition, although it was determined that freezing was performed when the outside air temperature is 3 ° C., the reference temperature may be changed to a temperature lower than 3 ° C. depending on the usage conditions of the caution information notification system 31, or the user may It may be settable.

  In addition, the weather information acquisition unit 16 acquires the weather information, and determines the freezing based on whether it has been raining or snowing until a predetermined time before and when it has not rained or snowing until the predetermined time. You may change the temperature of For example, if it is raining or snowing, the reference temperature may be 3 ° C., and if it is not raining or snowing, the reference temperature may be 0 ° C. The ease with which the road surface is frozen changes depending on whether the road surface is frozen or dry, so that the road surface can be determined more accurately. The predetermined time for determining the degree of dryness of the road may generally be set by the time until the road dries, and may be set by the user according to his / her preference. In addition, the reference temperature for road surface freezing is 3 ° C if the road is wet, and 0 ° C if the road is dry, but this reference can be changed appropriately according to the usage conditions, and the user prefers his own It may be set by.

  Alternatively, the outside of the vehicle may be photographed by the camera outside the vehicle 13 to determine whether the road surface is frozen. Thereby, the road surface can be determined more accurately.

  Thus, by detecting the freezing of the road surface and notifying the user of the caution information, the user can be prompted to drive safely and improve the safety. Also, if the user is notified in advance and the user searches for a detour, the safety and comfort of the user will be improved.

  Note that the road surface may be determined to be frozen from the temperature acquired by the weather information acquiring unit 16 without using the outside air temperature acquiring unit.

Third Embodiment
The caution information notification system according to the third embodiment will be described below with reference to the drawings.

  FIG. 6 is a diagram showing the configuration of the caution information notification system of the third embodiment.

As shown in FIG. 6, the caution information notification system 41 includes the vehicle 2 and the information center 3. The vehicle 2 has a pedaling force detecting means 4, a position information acquiring means 5 for acquiring position information of the vehicle 2, a time acquiring means 8 for acquiring time when the pedaling force is detected, and a car outdoor camera 13 for photographing the outside of the car It has communication means 6 for communicating treading force information, position information, time information and vehicle exterior information, and notification means 7 for notifying attention information obtained from the communication means 6. The information center 3 includes a caution information determination unit 14 that determines caution information based on treading force information and position information, and a communication unit 15 that communicates with the communication unit 6.

  Since the caution information notification system 41 has the time acquisition means 8, it can be transmitted to the information center 3 in association with the pedal effort information, the position information and the time information. As a result, the caution information determination unit 14 can acquire the time when the driver suddenly applied the brake and the time when the driver drove slowly. Thereby, in addition to the determination of the attention information of the first embodiment, the detailed determination of the attention information described below can be performed.

  The caution information notification system 41 can change with time, and can determine particularly periodic caution information. Examples of periodical caution information include caution information that occurs at a certain degree of time, such as the time a child often travels or a truck that regularly arrives at a store. The determination of the time that a child often travels can be determined by combining it with position information. Schools, parks, and school zones are nearby, and there is a high probability that the children will jump out on the road when mornings go to school, evenings after school, or when children return home before dinner such as 17:00. At this time, by accumulating the information that the driver at the place suddenly brakes, it is possible to determine the caution information that there are many children jumping out. Also, if there is a lot of sudden braking in the same time zone in the early morning near a store such as a supermarket, it is possible for the truck to park on the road in front of the store and the driver's visibility worsens, and the sudden braking is applied. Sex is high. Here, by further combining the detection results of the steering operation detection means 12, it can be determined whether the driver is trying to avoid the vehicle 2 parked on the road. Thereby, it is possible to determine the caution information that there is a vehicle 2 that regularly parks on the street. Alternatively, the outside of the vehicle may be photographed using the outside camera 13 and the information on the outside of the vehicle may be transmitted to the information center 3 in association with the pedaling force information. By using the camera 13 outside the vehicle, it is possible to more accurately determine the caution information such as whether there is a jump out or avoiding parking on the road. The user can be notified of such caution information to prompt safe driving, or the user can search for a detour. This improves the safety and comfort of the user.

  Although the caution information notification system 41 acquires the time when the pedaling force is detected by the time acquiring unit 8, the communication unit 15 acquires pedaling information such that the vehicle 2 and the information center 3 constantly communicate. The time may be acquired by the information center 3. By doing so, the vehicle 2 does not have to have the time acquisition means 8, so the space used by the caution information notification system 41 in the vehicle 2 can be saved.

Embodiment 4
The caution information notification system of the fourth embodiment will be described below with reference to the drawings.

  FIG. 7 is a diagram showing the configuration of the caution information notification system of the fourth embodiment.

The vehicle 2 has a treading force detecting means 4, a position information acquiring means 5 for acquiring position information of the vehicle 2, a humidity detecting means 10 for detecting humidity outside the vehicle, and a wiper operation detecting means 11 for detecting the operation of the wiper. Outside camera 13 for taking pictures of the outside of the vehicle, communication means 6 for communicating depression force information, position information, humidity information, wiper operation information, outside vehicle information, and notification means for notifying attention information acquired from communication means 6 7 and. The information center 3 includes a caution information determination unit 14 that determines caution information based on treading force information and position information, and a communication unit 15 that communicates with the communication unit 6.

Since the caution information notification system 51 can detect the humidity outside the vehicle, it can accurately detect the wetness of the road surface due to rainfall or snowfall.

  Also, by acquiring information on rainfall or snowfall up to the present time or a predetermined time in the weather division acquisition unit 15, it is possible to more accurately determine the wetness of the road surface. The predetermined time may be changed as appropriate depending on the use application of the caution information notification system 51, or the user may freely set it according to preference.

  Alternatively, the outside of the vehicle may be photographed using the outside camera 13 and the warning information may be determined in combination with the pedaling force information. In this way, it is possible to judge attention information more accurately.

  In this way, it is possible to urge the user to drive safely and improve the safety by detecting the wetness of the road surface and notifying the user of the caution information. Also, if the user is notified in advance and the user searches for a detour, the safety and comfort of the user will be improved.

  Note that the warning information may be determined using only the weather information acquired by the weather information acquiring unit 16 without using the humidity detection unit 10.
