  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In the present embodiment, a case where the present invention is applied to a driving advice device mounted on a vehicle will be described.

  As shown in FIG. 1, the driving advice device 10 according to the first embodiment includes a travel time measuring unit 12 that measures the time from the start of the engine of the own vehicle until the engine is turned off as a travel time, rapid acceleration, Based on the number of sudden decelerations, the driving diagnosis unit 14 that evaluates the dangerous driving degree indicating the degree of dangerous driving of the driver, the route acquisition unit 16 that acquires route information indicating the route of the driving course, and the time during driving And a clock unit 18 to be acquired.

  The driving diagnosis unit 14 obtains acceleration and deceleration from the acceleration sensor 20 provided in the host vehicle, and obtains average values of accelerations and decelerations that are greater than or equal to predetermined values generated per driving unit time and the number of decelerations. Then, the number of sudden accelerations and sudden decelerations are measured, and the dangerous driving degree is evaluated based on the measured number of sudden accelerations and sudden decelerations.

  The route acquisition unit 16 acquires the latitude and longitude of the traveling course from the GPS 22, acquires the intersection ID number registered in the electronic data corresponding to the acquired latitude and longitude, and includes time-series data of the intersection ID number. Get route information.

  The driving advice device 10 generates travel record data based on the travel time of the travel time measuring unit 12, the dangerous driving degree of the driving diagnosis unit 14, the route information of the route acquisition unit 16, and the time of the clock unit 18. A travel record data generation unit 24 and a travel record database 26 that stores and accumulates the travel record data generated by the travel record data generation unit 24 are provided.

  As shown in FIG. 2, the travel record data generation unit 24 adds rapid acceleration on the route to be recorded and route information including time series data of intersection ID numbers and passage dates (date information, time information) of each intersection. Data including the dangerous driving degree evaluated based on the number of sudden decelerations and travel time on the route to be recorded is generated as travel record data.

  The travel record database 26 stores travel record data for each route traveled in the past, as shown in FIG.

  Further, the driving advice device 10 searches the travel record database 26 for travel record data that travels the same route as the current travel route in the same time zone, and the dangerous drive degree in the current travel is the past dangerous drive degree. Than the past travel by the determination processing unit 28 and the determination processing unit 28 that determine whether the current travel time is less than or equal to the upper limit value of the predetermined range including the past travel time. When it is determined that the dangerous driving level is small and the difference between the current travel time and the past travel time is less than or equal to the predetermined value, the driving risk is low and the travel time is greatly different for the current driving. And an information presenting unit 30 that presents information indicating that there is no information to the driver and provides driving advice.

  Here, the relationship between the dangerous driving degree and the travel time will be described. It has been examined in some experiments in actual driving and driving simulators that there is no great difference in travel time even when driving with a high degree of dangerous driving such as first-time driving. For example, an experiment conducted in Switzerland in the literature (“Hurry to drive fast, human science to prevent traffic accidents”, Katsuya Matsunaga, Kazunori Shidera, Kazuaki Koshi, Yuji Matsuki, Nakanishiya Publishing, 2002) Has been introduced. According to the experiment in this document, one vehicle is run as fast as possible (first driving) at a distance of 1740 miles (about 2784 km), and the other vehicle is running at a safe speed. As a result, the driver who made a quick run was able to reduce the time by about 6% compared to the drive time of the driver who made the safe run, but the number of sudden brakes was 7 times faster than the safe run. Driving has reached 184 times and 26 times.

  When the determination processing unit 28 of the driving advice device 10 searches for the same route as the current route, the time-series data that completely matches the time-series data of the intersection ID number of the current route is stored in the past. Search from the time series data of the intersection ID number of the route. Even when the time-series data of the current route matches a part of the time-series data of the past route, the travel record data is searched as the same route. Further, in the predetermined range regarding the travel time determination condition in the determination processing unit 28, a range in which the driver does not feel that the travel time has become longer is statistically obtained, and a value indicating this range is set. Further, whether or not they are in the same time zone is determined based on whether or not the time zones including the traveling time are the same among a plurality of predetermined time zones.

  Next, the operation of the driving advice device 10 according to the first embodiment will be described. First, when the driver turns on the engine key and starts the engine, the driving advice device 10 executes a determination processing routine shown in FIG.

  In step 100, travel record data generation processing is performed during travel, and route information is acquired by the route acquisition unit 16 at any time, time is acquired by the clock unit 18, and acceleration and deceleration are acquired by the driving diagnosis unit 14. Then, the number of sudden accelerations and sudden decelerations is measured, and the dangerous driving degree is evaluated.

  In step 102, it is determined whether or not the engine has been turned off. If the engine is running, it is determined that the destination has not yet been reached, and the process returns to step 100. It is determined that the vehicle has arrived at the destination, and the process proceeds to step 103 where the travel time is measured by the travel time measuring unit 12 and, in step 104, the measured travel time is added to the travel record data generated in step 100. And registered in the travel record database 26.

  In the next step 106, travel record data that is the same route as the current determination target route and in the same time zone as the current determination target travel time is searched from the travel record database 26. It is determined whether or not there is travel record data for the route and the same time zone. Here, when there are a plurality of corresponding travel record data, the travel record data that minimizes the travel time is set as a comparison target. In addition, you may make it compare with any one of applicable some driving | running | working recording data, without limiting to a thing with a minimum travel time.

  In the above step 108, when there is no travel record data having route information of time series data that completely matches the time series data of the intersection ID number of the current route, or even if the route is the same, the time of the same time zone When there is no travel record data having route information, the determination processing routine is terminated, but the route information of the time series data completely matches the time series data of the intersection ID number of the current route, and If there is travel record data having route information of the time in the same time zone, in step 110, the retrieved travel record data is compared with the current travel record data generated in step 100, and this travel record data is compared. The dangerous driving degree in is lower than the dangerous driving degree of the searched past driving record data, and the travel time of this time is the trip of the searched past driving record data. Predetermined range comprised between (e.g., current + 10% of the travel time) equal to or smaller than the upper limit value of.

  In the above-described step 110, if the current dangerous driving degree is equal to or higher than the dangerous driving degree of the searched past driving record data, or the current travel time indicates the travel time of the searched past driving record data. If it is larger than the upper limit value of the predetermined range, it is determined that the advice is unnecessary, and the determination processing routine is ended. On the other hand, the current dangerous driving degree is smaller than the dangerous driving degree of the searched past traveling record data, and the current travel time is an upper limit value within a predetermined range including the traveling time of the retrieved past traveling record data. If it is the following, it is determined that advice is necessary, and in step 112, the current driving is less dangerous than the past driving, and the travel time is significantly different from the past travel time. The information indicating that there is no information is presented by a display (not shown) or voice provided in the vehicle, the driver is advised, and the determination processing routine is terminated.

  As described above, according to the driving advice device according to the first embodiment, the current travel time on the route to be determined is equal to or lower than the upper limit value of the predetermined range including the past travel time, If the dangerous driving degree is smaller than the past dangerous driving degree, information indicating that the current driving is less dangerous than the past driving and the travel time is not much different from the past travel time. By presenting to the driver, even if you drive more safely than in the past, you will notice that there is no big difference in travel time, and you will feel the benefits of improved safety, thereby improving the driving safety of the driver Can do.

  Also, depending on the judgment result, even if you drive more safely than in the past, the judgment result is presented to the driver and advised only when there is no significant difference in travel time and you can feel the benefits of improved safety. In other cases, the driver is not advised and can be advised only when there is a merit to advise.

  In addition, since the current travel record data of the route to be determined is determined by comparing with the past travel record data in the same time zone as the travel time, there is no significant difference in travel time even if driving safely from the past. It can be determined under the same conditions.

  Until autonomous driving is realized, the configuration of the car is in the form of a human-machine cooperative system between the driver and the car, and the concept of driver sovereignty has been adopted as its design concept, and will it fall into a dangerous situation? It is inevitable that it depends heavily on the driving of the driver. Therefore, in aiming for zero accidents, it is considered essential to guide the driver's driving behavior in the direction of safe driving and improve the driver, according to the driving advice device according to the present embodiment, Driving the driver in the direction of safe driving can improve the driver.

  In addition, the driver can only benefit the safety by notifying the driver that the travel time is not much different from the previous driving (when the same course was run at the same time) but the safety level increased. Because it is possible to teach that there is a driver, the driver feels that he / she is profitable and can be convinced to transform his driving behavior into safe driving.

  In the above embodiment, the case where the predetermined range as the determination condition is set as a ratio with respect to the current travel time has been described as an example. However, the range is set to be a predetermined time longer than the current travel time. May be. In that case, a time that the driver does not feel that the travel time has become longer is statistically obtained, and a value indicating this time is set as a predetermined time.

  In addition, the case where it is determined that the destination has been reached when the engine is turned off and the generation of the travel record data is finished has been described as an example, but the car navigation system installed in the own vehicle is used, such as home or office The travel time may be calculated by estimating the arrival time based on the registration information.

  Moreover, although the case where acceleration and deceleration were measured from the acceleration sensor was described as an example, the difference between the initial speed and the final speed in the sudden acceleration state and the sudden deceleration state was obtained by the speed sensor, and the acceleration was measured. Also good.

  Moreover, although the case where the dangerous driving degree was evaluated using the number of sudden accelerations and the number of sudden decelerations was explained, a speed sensor and a driving operation amount sensor are further provided so that the dangerous driving degree is evaluated using the speed and the driving operation amount It may be.

  In addition, when the current travel time on the route to be determined is less than or equal to the upper limit of the predetermined range including the past travel time, and the current dangerous driving degree is smaller than the past dangerous driving degree, the case where advice is given Although described as an example, information indicating the determination result may be presented to the driver regardless of the determination result.

  Next, a driving advice device according to the second embodiment will be described. Note that the configuration of the driving advice device according to the second embodiment is the same as that of the first embodiment, and thus the same reference numerals are given and description thereof is omitted.

  In the second embodiment, the driving diagnosis unit evaluates the degree of safe driving indicating the degree of safe driving of the driver based on the frequency per unit time of sudden start and sudden braking. The form is different.

  In the driving advice device 10 according to the second embodiment, the traveling record data generating unit 24 generates traveling record data including the evaluated safe driving degree and registers it in the traveling record database 26.

  Further, in the determination processing routine according to the second embodiment, the travel record data having the same route and the same time zone as the searched current time is compared with the current travel record data, and the safe driving degree in the current travel is compared. Is greater than the safe driving degree of the searched past travel record data, and the current travel time is equal to or less than the upper limit value of the predetermined range including the travel time of the retrieved past travel record data Determine. Then, the current safe driving degree is larger than the safe driving degree of the searched past travel record data, and the current travel time is an upper limit value of a predetermined range including the travel time of the searched past travel record data. When it is below, it is judged that advice is necessary, and this driving shows that the driving degree of safe driving is higher than the past driving and the travel time is not much different from the past travel time. The information is presented by a display or sound provided in the vehicle, and the driver is advised.

  In this way, if the current travel time on the route to be determined is less than or equal to the upper limit of the predetermined range of past travel time and the safe driving degree is greater than the past safe driving degree, the fact is indicated to the driver. By giving advice, it is possible to improve the driver's driving safety by notifying that there is no great difference in travel time even if driving safely from the past and feeling the merit of improved safety.
