  FIG. 3 is a flowchart showing a flow of characteristic processing executed by the advice providing system 1 according to the present embodiment. This flow is repeatedly executed with a predetermined cycle, for example.

  First, the information provision judgment part 40 inputs the various information memorize | stored in the memory 30 (S100). Furthermore, it instructs the center communication unit 70 to obtain information to be provided to the user from the information center 100 (S102).

  Then, it is determined whether or not to provide information. If it is determined that information is to be provided, the content of advice is determined (S104, 106). If it is determined not to provide information, the processing from S100 is executed again.

  Subsequently, the advice determination unit 50 determines whether or not it is appropriate to give advice (S108). The determination is made so as not to give advice in a scene where the driving load is heavy, such as during a right turn or during high speed traveling. For example, information acquired from the vehicle by the information acquisition unit 20 is input via the information provision determination unit 40 with respect to the situation of the vehicle serving as the determination material. If it is determined that it is not appropriate to give advice, the processing from S100 is executed again.

  Then, the advice determination unit 50 waits until the timing suitable for guidance is reached (S110). Note that processing such as returning to S100 may be performed when a predetermined time has elapsed.

  The advice determination unit 50 determines whether or not the same guidance has been given most recently (S112).

  If the same guidance has not been provided recently, advice is provided in a normal manner (S114). On the other hand, if the same guidance has been given most recently, the content is changed and advice is provided (S116). This change in content may be divided according to whether or not the user has followed the latest advice. For example, when the user follows the latest advice, the advice is provided with a weaker tone (including omission), and when the user does not follow the latest advice, the advice is provided with a stronger tone.

  Then, it is determined whether or not the user has followed the current advice, the result is stored in the memory 30 (S118), and one routine of this flow is terminated.

  Here, a specific example of advice determined by the information provision determination unit 40 will be described. For example, if the user is driving the vehicle within normal use, based on the vehicle function information 33, “(△ vehicle name) ○○ can also use the function of △△. Message is output. If the user gives a positive response to the HMI 60, detailed information will be described. At this time, when displaying an image in the HMI 60, it is preferable to match (or similar) the screen displayed on the vehicle that the user is driving normally (the same applies hereinafter).

  Further, based on the travel history 32, a message such as “A new XX has been made. Here, XX is a newly created expressway or facility in the vicinity of the route on which the user normally travels. If the user gives a positive response to the HMI 60, detailed information will be described.

  In addition, referring to the operation history 31, when the braking performance is different from the vehicle that is driving normally, when the braking performance of the vehicle that is driving normally is higher, “please depress the brake pedal a little harder”, etc. A message is output, and a message such as “Please depress the brake pedal a little more slowly” is output when the braking performance of the vehicle that is driving normally is lower.

  In addition, referring to the operation history 31, when the driving performance at the time of starting is different from that of the vehicle that is driving normally, if the driving performance at the time of starting is higher than that of the vehicle that is driving normally, “When starting, make the accelerator pedal a little stronger. Please output a message such as “Please depress”, and when the vehicle that is driving normally has lower driving performance when starting, a message such as “Please depress the accelerator pedal a little more slowly when starting” is output.

  Also, referring to the operation history 31, if the steering ratio is different from the vehicle that is driving normally, when the steering ratio of the vehicle that is driving normally is larger, "Please turn the steering wheel a little larger", etc. A message is output, and a message such as “Please turn the steering wheel a little smaller” is output when the steering ratio of the vehicle that is driving normally is smaller.

  Further, referring to the vehicle function information 33 and the navigation information, when there is a downhill in the traveling destination of the vehicle, and the currently driving vehicle is a hybrid vehicle and has the B range function, , More energy can be recovered ". In addition, when there is an uphill on the destination of the vehicle, a message such as "Please depress the accelerator pedal a little harder" or "Depress the accelerator pedal a little more slowly" is output according to the difference in driving performance. .

  In addition, referring to the vehicle function information 33 and the navigation information, when there are continuous tunnels at the destination of the vehicle, if the vehicle that is currently driving has the AUTO light function, “the road is a continuous tunnel. A message such as “Would you like AUTO light?” Is output. On the other hand, if the user does not follow, for example, a message such as “If the AUTO light is used, an on / off operation is not necessary” is output (a specific example of S116).

  In addition, referring to the vehicle function information 33 and the navigation information, a message such as “The neighborhood is getting darker. Do you want to turn on the light?” Is output when driving around the vehicle with insufficient illuminance. To do. If the vehicle does not respond to this and the currently driven vehicle has the AUTO light function, a message such as “If the AUTO light is used, an on / off operation is not required” is output.

  In addition, referring to the vehicle function information 33 and the navigation information, when the road on which the vehicle is traveling is congested, if the vehicle that is currently driving has an ACC (Adaptive Cruise Control) function, “the front vehicle following system is used. "?" Is output. When the user makes a positive response to the HMI 60, the position of the ACC start switch is notified. If the user responds negatively or does not respond, a message such as “There is a system button that can follow the front car” is output.

  As described above, according to the advice providing system 1 of the present embodiment, it is possible to provide advice adapted to the user based on the operation history 31, the traveling history 32, and the user information 34.

  Also, because it is configured as a portable device, it can bring in the information collected in the vehicle that the user normally drives, and provide appropriate advice, especially when the user drives a vehicle that is not normally driven. it can.

  In addition, since navigation information is taken into consideration and whether or not advice is given and appropriate timing is determined, it is possible to prevent the driver from feeling uncomfortable.

  In addition, in cooperation with the in-vehicle navigation device 84, advice is given in consideration of route information (distance to destination, presence / absence of hill, traffic situation, presence / absence of tunnel), so that the user can drive the vehicle efficiently. it can.

  In addition, since the advice is given in consideration of the schedule and traffic conditions, effective driving support can be performed.

  Further, the accuracy of personal authentication can be improved using the user information 34, and information on the network can be collected using the user information 34.
