  The control means 4 is mainly composed of a microcomputer having a CPU, a ROM, a RAM, an I / O (input / output) interface, and the like. The control unit 4 performs a matching process on the position data received by the GPS receiving unit 2 and the caution area data downloaded via the mobile phone 8, and notifies the warning information by the notification unit 5 according to the result of the matching process. To do. The control means 4 has storage means 4a such as a flash memory for storing the downloaded caution area data, and can process and store the caution area data. The storage unit 4a stores personal authentication information and personal driving information that can be set according to the personal authentication information. This personal driving information is information related to driving for each driver that is authenticated by the personal authentication information, and includes, for example, total traveling distance, driving frequency, driving time of the day, frequency of sudden braking, average vehicle speed, and the like. In the present embodiment, it is assumed that the total driving distance, the driving frequency, and the driving time of the day are stored as the personal driving information. Here, the “running frequency” indicates the number of times of entering or passing through a predetermined area set by map data or latitude / longitude data. The control means 4 calculates the skill level of the driver according to the personal driving information stored in the storage means 4a, and determines whether the warning information should be notified based on the skill level. It has a notification processing function.

  The notifying means 5 is composed of, for example, a matrix type liquid crystal display panel or an organic EL panel, and a display unit 5a that is visual information confirmation means for displaying warning information, and a speaker 5b that is auditory information confirmation means for notifying warning information by voice. And the display unit 5a and the speaker 5b operate according to an instruction signal from the control unit 4.

  The display unit 5a displays a first display area 51 for displaying various vehicle information such as the accumulated distance of the vehicle, remaining fuel, or outside air temperature, and a second display for displaying warning information based on the normal operation state and the caution area data. Display area 52. FIG. 2 shows a display form of the display unit 5a during normal driving of the vehicle. Various vehicle information displayed in the first display area 51 is input to the control means 4 from various units such as an engine control unit (ECU) and an air control unit via a multiple communication path. 4 can display various vehicle information by executing a predetermined display process. Further, the display unit 5a changes the display color of the second display area 52 to “blue” during normal driving and “red” when the vehicle enters the caution area. This is a warning display section that calls attention.

  Next, a control method in the personal driving information reading process will be described with reference to FIG. When the control unit 4 detects an input to turn on the ignition switch (power switch), the control unit 4 starts communication with the mobile phone 8 in step S <b> 1 and acquires the personal authentication information from the mobile phone 8 through the communication unit 1. Next, the control means 4 determines whether or not the acquired personal authentication information has been registered in the storage means 4a (step S2). If it has not been registered, the control means 4 shifts to a registration mode (step S3). ). FIG. 4 shows a display example in the registration mode. The driver inputs a name by a predetermined operation of the operating means 3 and registers new personal authentication information. Thereafter, the personal driving information corresponding to the personal authentication information is stored in the storage means 4a.

  Further, the control means 4 determines whether or not a plurality of pieces of personal authentication information have been acquired (step S4). If a plurality of pieces of personal authentication information have been acquired, the control means 4 shifts to a driver selection mode (step S5). FIG. 5 shows a display example in the driver selection mode. In the second display area 52, a name registered according to the acquired personal authentication information is displayed, and the driver selects the driver by a predetermined operation of the operation means 3.

  When the driver is specified through steps S1 to S5, the control means 4 reads the personal driving information corresponding to the acquired and selected personal authentication information from the storage means 4a (step S6), and performs the second processing. The personal driving information is displayed in the display area 52 (step S7). FIG. 6 is a diagram showing a display example of the personal driving information. The second display area 52 of the display unit 5a displays a list of the personal information and the skill level of the driver set by a method described later, and the driver confirms his / her personal driving information before starting driving. be able to. The “running frequency” displayed in FIG. 6 indicates the running frequency of a predetermined area including the position data of the host vehicle obtained through the GPS receiving unit 2.

  Next, a control method for setting the skill level of the driver will be described. When the personal driving information corresponding to the personal authentication information acquired from the mobile phone 8 is read and processed, the control unit 4 is configured to perform plural processing based on the total driving distance, the driving frequency, and the driving time of the day as the personal driving information. Set the driver's skill level of the rank. In the present embodiment, the skill level is classified into ranks 1 to 5, with rank 1 having the lowest skill level and rank 5 having the highest skill level. Specifically, the control means 4 first obtains the skill level based on the skill level matrix composed of the total travel distance and the travel frequency shown in FIG. In the skill level matrix of FIG. 7, “running frequency” is the running frequency of a predetermined area including the position data of the host vehicle, and changes as the vehicle travels. For example, when the total travel distance is “5,000 km or more and 10,000 km or less” and the travel frequency is “several times a year”, the skill level obtained from the skill level matrix is rank 3. Furthermore, the control means 4 sets the skill level one rank lower than the rank obtained from the skill level matrix when the driving time of the day as the personal driving information is a predetermined value or more (rank-1 according to the skill level matrix). ). When the skill level obtained from the skill level matrix is rank 3 and the operation time of the day is equal to or greater than a predetermined value, the skill level is set to rank 2. As a result, when the driving time of the day is long and the attentiveness is low, the skill level can be set low and the skill level can be made more appropriate according to the state of the driver.

  Further, the control means 4 corrects the skill level according to the driving situation of the driver. Specifically, for example, when the traveling speed of the vehicle is equal to or higher than a predetermined value, the control means 4 corrects the skill level one rank lower than the set rank (set rank-1). If the skill level set by the skill level matrix and the driving time of the day is set to rank 2, and the vehicle traveling speed is equal to or higher than a predetermined value, the skill level is corrected to rank 1. Thereby, when the driver is driving unsafely, the skill level can be set low and the skill level can be made more appropriate according to the actual driving situation. Other information related to the driving situation includes engine speed, engine intake pressure and steering wheel steering angle, outside air temperature, wiper operation ON / OFF conditions, vehicle-to-vehicle distance obtained using inter-vehicle communication, and other vehicle It is also possible to correct the skill level according to external information such as vehicle speed information.

  Further, the control means 4 can arbitrarily change the skill level according to a predetermined operation of the operation means 3. For example, when the driver needs to notify more detailed warning information, the driver can arbitrarily change the skill level that is automatically set to obtain notification of the warning information that meets the finer preference.

  Next, a control method in the individual notification processing function of the control means 4 will be described with reference to FIG.

  The control means 4 inputs caution area data from the server 6 via the mobile phone 8 (step S11), and also inputs position data of the host vehicle via the GPS receiver 2 (step S12). Then, the control means 4 determines whether or not the position of the own vehicle is in the attention area based on the inputted attention area data and the position data of the own vehicle (step S14), and the input said It is determined whether or not the warning level of the caution area data should be notified to the driver's skill level set by the above-described method. In determining whether or not the position of the host vehicle is in the caution area, it is obtained by matching processing between the caution area data and the position data. Further, in the determination of whether or not the warning level should be notified, the warning level rank of the caution area data to be input is set in advance in accordance with the skill level rank as shown in FIG. Judgment is made based on whether or not the rank is met.

  When it is determined that the position of the own vehicle is in the caution area and the warning level of the caution area data is to be notified to the skill level of the driver, the control means 4 displays the second display area 52. The warning information regarding the attention area data is displayed, and a part of the background of the second display area 52 is color-changed to execute a process of visually warning the user of the vehicle, and by the speaker 5b. A process of aurally alerting the warning information is performed (step S15).

  Specifically, when the attention area data relates to a first attention area that is an intersection indicating a location where collision occurs frequently, for example, the control means 4 displays an image and characters that call attention to the collision at the intersection in the second display area 52. A part of the background is displayed in “red”, and a process of issuing a warning “This is an intersection. Be careful of collision” is executed by the speaker 5b (see FIG. 10).

  In addition, when the attention area data relates to the second attention area, which is an area where frequent accidents occur when turning left, the control means 4 displays an image and characters that call attention to the involvement during left turning in the second display area 52. At the same time, a part of the background is colored “red”, and a process of issuing an alarm “turn left. Be careful of entrainment” is performed by the speaker 5b (see FIG. 11).

  In this driving support device A, the control means 4 sets the skill level of the driver based on the personal driving information, determines that the vehicle is in the caution area, and the warning level of the caution area data is When it is determined that the user's skill level should be notified, the individual notification processing function for permitting the notification operation by the display unit 5a and the speaker 5b of the notification unit 5 is provided. Further, the control means 4 stores the personal driving information stored in the storage means 4a corresponding to the personal authentication information received by the communication means 1 that receives the personal authentication information from the mobile phone 8 owned by the driver. It is read out. The personal driving information includes at least one of a driving distance, a driving frequency, and a driving time.

  Due to this feature point, the driving support device A notifies the user of the warning information about the attention area data determined to be necessary based on the experience of driving for each individual who becomes the driver of the vehicle, thereby making the user troublesome. This makes it possible to suppress the feeling and allows the user to perform safe driving.

  Further, the driving support device A can make the skill level more appropriate according to the actual driving situation by correcting the skill level of the driver based on the driving situation of the driver by the control means 4. .

  In addition, the driving support device A allows the driver to arbitrarily change the skill level by allowing the control means 4 to change the skill level of the driver according to the operation signal from the operation means 3, and more setting. The degree of freedom can be provided.
