The driving operation change information associated with the matching driving operation condition and the road attribute condition that matches the road attribute information is acquired.

  For example, the driving operation information stored in the driving operation information storage unit 11 is “speed = 60 km / h”, and the driving operation condition stored in the driving support change management information storage unit 163 is “speed ≧ 50 km / h”. ”, The driving support change information acquisition unit 164 determines that the driving operation information matches the driving operation condition, and determines the driving support change information associated with the driving operation condition as the driving support change management information. Obtained from the storage means 163.

  Further, for example, the driving operation information and the road attribute information stored in the driving operation information storage unit 11 are “speed = 30 km / h, road shape = intersection”, and are stored in the driving support change management information storage unit 163. If the driving operation condition and the road attribute condition are “(speed ≧ 30 km / h) & {road shape = (intersection | near intersection)}”, the driving support change information acquisition unit 164 includes the driving operation information and the road attribute. Information is determined to match the driving operation condition and the road attribute condition, and the driving support change information associated with the driving operation condition and the road attribute condition is acquired from the driving support change management information storage unit 163. To do.

  In addition, the driving support change information acquisition unit 164 is, for example, two or more stored in the driving operation information storage unit 11 in accordance with the contents of statistical processing indicated by the driving operation conditions stored in the driving support change management information storage unit 163. The operator operation information may be statistically processed. Then, the driving support change information acquisition unit 164 determines whether or not the result of the statistical processing matches the driving operation condition, and acquires one or more driving support change information associated with the matching driving operation condition. May be.

  For example, when the driving operation condition stored in the driving support change management information storage unit 163 is “average speed ≧ 50 km / h”, the driving support change information acquisition unit 164 stores the driving operation information according to the driving operation condition. The average speed is calculated using the speed information among the driving operation information stored in the unit 11. For example, when the average speed is “55.5 km / h”, the driving support change information acquisition unit 164 determines that the average speed matches the driving operation condition, and associates it with the driving operation condition. The obtained driving support change information is acquired from the driving support change management information storage unit 163.

  Further, for example, when the driving operation condition and the road attribute condition stored in the driving support change management information storage unit 163 are “(average speed ≧ 60 km / h) & (average road curvature ≦ 400 m)”, the driving support change The information acquisition unit 164 obtains the driving operation information in which the speed information and the road curvature information are associated with each other among the driving operation information stored in the driving operation information storage unit 11 according to the driving operation condition and the road attribute condition.

For example, when the average speed and the average road curvature are “62.3 km / h” and “389 m”, the driving support change information acquisition unit 164 indicates that the average acceleration and the average road curvature indicate the driving operation. It is determined that the condition matches the road attribute condition, and the driving support change information associated with the driving operation condition and the road attribute condition is acquired from the driving support change management information storage unit 163.

  The driving support information acquisition unit 165 normally manages one or more driving support information associated with driving operation conditions that match one or more driving operation information stored in the driving operation information storage unit 11, as driving support management. Obtained from the information storage means 161. For example, when one or more pieces of driving operation information are stored in the driving operation information storage unit 11, the driving support information acquisition unit 165 displays driving support information associated with driving operation conditions that match the driving operation information. get. For example, when one or more driving operation information and one or more road attribute information are stored in association with each other in the driving operation information storage unit 11, the driving support information acquisition unit 165 matches the driving operation information. And driving support information associated with the road attribute condition that the road attribute information matches. Note that the method and procedure for acquiring the driving support information are the same as those for acquiring the driving support change information by the driving support change information acquiring unit 164, and thus the description thereof is omitted.

  Further, when the driving support change information acquisition unit 164 acquires the driving change information, the driving support information acquisition unit 165 acquires one or more driving support information stored in the driving support information storage unit 162, and the driving support information The information is changed according to the content of the change indicated by the driving support change information acquired by the driving support change information acquisition unit 164, and the changed driving support information is acquired.

  For example, when the acquired driving support information is “turn left after 10 seconds” and the acquired driving support change information is “time × 3”, the driving support information acquisition unit 165 includes the driving support information. “10 seconds” is tripled to obtain the changed driving support information “turn left after 30 seconds”. Further, for example, when the acquired driving support information is “the distance between the vehicles is Nm” and the acquired driving support change information is “distance: 100 m”, the driving support information acquiring unit 165 indicates that the driving support information is The symbol “N” indicating replacement with the existing distance and “100” are replaced, and the driving support information “the inter-vehicle distance is 100 m” after replacement is acquired. Further, for example, when the acquired driving support information is “Please pay attention to TARGET” and the acquired driving support change information is “target: sudden start”, the driving support information acquisition unit 165 includes the driving support information. Is replaced with the symbol “TARGET”, which indicates that the target is to be replaced, and “sudden start”, and the driving support information “Please be careful about sudden start” after replacement is obtained.

  The driving support information acquisition unit 165 may change the output condition of the acquired driving support information according to the driving support change information acquired by the driving support change information acquisition unit 164. For example, when the acquired output condition is “intersection time ≦ 10 seconds” and the acquired driving support change information is “time × 2”, the driving support information acquisition unit 165 includes “10 seconds” included in the output condition. "Is doubled, and the changed output condition" intersection time ≤ 20 seconds "is acquired. Further, for example, when “intersection distance ≦ 100 m” and the acquired driving support change information is “distance × 3”, the driving support information acquisition unit 165 triples “100 m” included in the output condition ” Then, the changed output condition “intersection distance ≦ 300 m” is acquired.

  The output unit 17 outputs driving support information. The output unit 17 normally outputs driving support information according to the output conditions of the driving support information. For example, when the driving support information acquired by the driving support information acquisition unit 16 has the output condition “right turn: 500 m”, the output unit 17 sequentially acquires the distance from the current position to the right turn point, and the distance Is determined to be 500 m. When the distance is 500 m, driving support information is output. In addition, the output part 17 outputs driving assistance information normally by each means mentioned later.

  The current speed information acquisition unit 171 acquires current speed information indicating the current speed of the moving object. The current speed information acquisition unit 171 can be usually realized by hardware (dedicated circuit) such as a so-called vehicle speed sensor, but may be realized by an MPU, a memory, or the like. The processing procedure of the current speed information acquisition unit 171 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The intersection position information acquisition unit 172 acquires, from the road information storage unit 12, intersection position information indicating the position of the closest intersection among the intersections existing in the traveling direction of the moving object. The intersection position information acquisition unit 172 is usually an intersection that is shown to turn right or left by the route information stored in the road information storage unit 12 among the intersections existing on the route to the destination. Intersection position information indicating the position of the intersection is acquired. Note that the intersection may be an intersection indicated to travel straight by the route information. In addition, the route information is normally stored in the road information storage unit 12, but may be stored in an arbitrary storage area, or may be held by the intersection position information acquisition unit 172.

The intersection position information acquisition unit 172 acquires the intersection position information in the following procedure, for example.
(1) The current position information acquired by the current position information acquisition unit 13 is acquired.
(2) The road information identified by the road identifier included in the route information is acquired from the road information storage unit 12.
(3) The position information of the intersection indicated to turn right or left by the route information is acquired from the road information acquired in (2).
(4) The distance between the position indicated by the current position information acquired in (1) and the position information acquired in (3) is calculated.
(5) The position information of the intersection which is the shortest distance among the distances calculated in (4) is acquired.

  The intersection position information acquisition unit 172 is an intersection that indicates that a right turn or a left turn is indicated by the route information indicating the route among the intersections existing on the route to the destination, and indicates the distance to the nearest intersection. You may acquire distance information. In this case, the intersection position information acquisition unit 172 acquires distance information indicating the shortest distance among the distances calculated in (4) instead of the position information in the above (5).

  The intersection approach scheduled time information calculation unit 173 calculates intersection entry scheduled time information that is a required time from the current position of the moving object to the intersection. The intersection approach scheduled time information calculation means 173 is an intersection that is shown to turn right or left by the route information indicating the route among the intersections existing on the route to the destination, and enters the intersection to the nearest intersection. Calculate scheduled time information.

The intersection approach scheduled time information calculation unit 173 calculates the intersection approach scheduled time information in the following procedure, for example.
(1) The current position information acquired by the current position information acquisition unit 13 is acquired.
(2) The current speed information acquired by the current speed information acquisition unit 171 is acquired.
(3) The intersection position information acquired by the intersection position information acquisition means 172 is acquired.
(4) A distance between the position indicated by the current position information acquired in (1) and the position indicated by the intersection position information acquired in (3) is calculated, and intersection distance information indicating the distance is acquired.
(5) The intersection distance information acquired in (4) is divided by the current speed information acquired in (2) to calculate intersection approach scheduled time information.

  In addition, when the intersection position information acquisition unit 172 acquires the intersection distance information, the intersection approach scheduled time information calculation unit 173 divides the intersection distance information by the current speed information acquired in the above (2), and plans to enter the intersection Time information may be calculated. Further, the intersection approach scheduled time information calculation unit 173 may acquire the intersection distance information acquired by the intersection position information acquisition unit 172.

  The object distance information acquisition unit 174 acquires object distance information indicating the distance from the current position of the moving object to the object. The current speed information acquisition unit 171 can be usually realized by hardware (dedicated circuit) such as a so-called inter-vehicle sensor or an apparatus that detects an obstacle, but may be realized by an MPU, a memory, or the like. The processing procedure of the current speed information acquisition unit 171 is usually realized by software, and the software is recorded on a recording medium such as a ROM.

  The output unit 175 outputs the driving support information acquired by the driving support information acquisition unit 16. The output unit 175 normally outputs the driving support information when the output condition of the driving support information is satisfied. For example, when the driving support information is information that guides the distance to an arbitrary point or object such as intersection distance guidance information, right turn point distance guidance information, and object distance guidance information, the output unit 175 outputs the point or object. Is the distance indicated by the distance guidance information, the time guidance information is output as driving support information. Further, for example, in the case of information that warns the state of the moving body, such as overspeed warning information or rapid acceleration warning information, the output unit 175, when the state satisfies the output condition of the warning information, Warning information is output as driving support information.

  For example, when the time indicated by the intersection approach scheduled time information acquired by the intersection approach scheduled time information calculation unit 173 is the time indicated by the intersection approach time guide information acquired by the driving support information acquisition unit 16, the output unit 175 Intersection approach time guidance information is output.

  For example, when the distance indicated by the object distance information acquired by the object distance information acquisition unit 174 is the distance indicated by the object distance guidance information acquired by the driving support information acquisition unit 16, the output unit 175 displays the object distance guidance. Output information.

  For example, the right turn point distance guidance information is “Turn right after 20 seconds”, and the intersection approach scheduled time information calculation means 173 sets the intersection approach scheduled time information as “25 seconds”, “24 seconds”, “23 seconds”. When the intersection approach scheduled time information becomes “20 seconds”, the output means 175 outputs the right turn point distance guidance information “Turn right after 20 seconds”.

  Further, for example, it is assumed that the object distance guidance information is a warning sound and the object distance guidance information has an output condition “distance ≦ 1 m”. When the object distance information acquisition unit 174 sequentially acquires the object distance information as “1.5 m”, “1.4 m”, and “1.3 m”, the output unit 175 indicates that the object distance information is When it becomes “1 m” or less, a warning sound as the object distance guidance information is output.

  For example, when it takes time to output the driving support information, the output unit 175 may output the driving support information before satisfying the output condition of the driving support information. For example, if it takes 2 seconds to output the right turn point distance guidance information, the output unit 175 may output the right turn point distance guidance information when the intersection approach scheduled time information reaches “22 seconds”. Good. For example, when the moving body travels 0.1 m during the output of the warning sound described above, the output unit 175 outputs the warning sound when the object distance information becomes “1.1 m”. Also good.

  Further, the output unit 175 determines whether or not the output conditions such as the intersection approach scheduled time information and the object distance information described above are met according to the output conditions of the driving support information acquired by the driving support information acquisition unit 16. Output determination target information, which is information for determining whether or not, may be acquired. For example, when the output condition is a speed condition related to the speed of the moving object such as “speed ≧ 60 km / h”, the output unit 175 acquires speed information as output determination target information. The speed information may be current speed information acquired by the current speed information acquisition unit 171 or driving operation information acquired by the driving operation information acquisition unit 14. For example, when the output condition is a road gradient condition related to a road gradient such as “gradient ≧ 10 ‰”, the output unit 175 acquires road gradient information as output determination target information. The road gradient information may be road gradient information acquired by the driving operation information acquisition unit 14.

The average speed is calculated using the speed information. Here, it is assumed that the average speed is “62.5 km / h”. Then, the driving support change information acquisition unit 164 determines that the driving operation information in FIG. 4 matches the driving operation condition, and acquires the driving support change information “time × 2” of “ID = 011” in FIG. 6. Further, at this time, the driving support change information acquisition unit 164 has the same driving operation conditions “ID = 012”, “ID = 013” driving support change information “distance × 1.5”, “volume × 120%” Is also acquired. “Volume × 120%” indicates that the volume when driving support information is output as voice is 120%.
