Description

  The present invention relates to a vehicle-mounted device, and more particularly to a vehicle-mounted device that detects an operating state of a device that is mounted on a vehicle and executes low fuel consumption traveling or the like.

  By detecting the operating state of a device that reduces the amount of fuel consumed by the vehicle and the amount of harmful substances discharged (hereinafter sometimes referred to as eco mode or eco driving mode), Technologies have been proposed that automatically support driving that reduces harmful substances and reduces adverse environmental impacts (hereinafter sometimes referred to as eco-driving, eco-driving, fuel-efficient driving, or environmental driving). . Eco-driving requires human effort, and even if an eco-driving mode is provided, people's awareness of eco-driving greatly affects fuel consumption. As a technology that supports the driver's eco-driving with one vehicle, Non-Patent Document 1 detects the state of eco-driving of the vehicle, scores the degree of execution of the eco-driving immediately or for each run, and gives the scoring result A technique for displaying to the driver is disclosed. In this device, when the eco mode is selected, if the driver performs a driving operation such as sudden acceleration or sudden deceleration, he / she recognizes that it is out of the eco driving area and is not in the eco driving state. A message indicating that the vehicle is not in the eco-drive area is displayed to the user. Thereby, it is detected whether or not the vehicle is actually running ecologically according to the behavior of the vehicle, and the display to the driver is made.

“Newly developed“ Ecological Drive Assist System ”to support driving with lower fuel consumption-Installed in the new hybrid vehicle“ Insight ”released in 2009”, [online], November 2008 20th, Honda Motor Co., Ltd. [Search February 2, 2009], Internet <URL: http://www.honda.co.jp/news/2008/4081120a.html>

  However, in the above technology, even if the eco-mode is selected and the device that reduces the fuel consumption of the vehicle and the emission of harmful substances is in operation, the driver can perform the rapid acceleration driving operation as necessary. In such a case, it is recognized that the vehicle is out of the eco-drive region and is not in the eco-drive state. In this case, since the device recognizes the vehicle as non-eco-driving even though the eco-mode is selected as the driver, the determination as to whether or not the vehicle is eco-friendly depends on the behavior of the vehicle. Even if the ratio of eco-driving for each travel process is displayed, it may not be possible to accurately represent the presence or absence of the driver's awareness of eco-driving.

  The present invention has been made in consideration of such circumstances, and its purpose is to more appropriately set the proportion of operating devices that are mounted on the vehicle and execute fuel-efficient driving, etc., regardless of the behavior of the vehicle. Another object of the present invention is to provide an in-vehicle device that can be calculated.

Therefore, it is possible to more appropriately calculate the proportion of devices that are installed in the vehicle and perform fuel-efficient driving, etc., regardless of the behavior of the vehicle. It becomes. That is, as a result, it is possible to accurately represent the presence or absence of the driver's consciousness trying to operate a device that performs low fuel consumption traveling or the like.

  In this case, it is preferable that the apparatus controls the vehicle so that harmful substances discharged from the vehicle are reduced in response to the operation of the driver of the vehicle.

It is possible to more appropriately calculate the proportion of operating devices that reduce harmful substances.

  In addition, it is preferable that the device controls the vehicle so that the fuel consumption with respect to the travel distance of the vehicle in a predetermined section is reduced in response to the operation of the driver of the vehicle.

  According to this configuration, the device controls the vehicle so that the fuel consumption with respect to the travel distance of the vehicle in a predetermined section is reduced in response to the operation of the driver of the vehicle, regardless of the behavior of the vehicle. Thus, it is possible to more appropriately calculate the rate at which the device that reduces fuel consumption is operating.

  Moreover, it is preferable to further include guidance means for urging the driver of the vehicle to operate the apparatus based on the ratio of the section in which the apparatus is operating calculated by the ratio calculating means.

  According to this configuration, since the guidance means prompts the driver of the vehicle to operate the apparatus based on the ratio of the section in which the apparatus was calculated calculated by the ratio calculation means, the ratio at which the apparatus is operating Accordingly, it becomes possible for the driver of the vehicle to operate the apparatus at a more appropriate rate.

  In this case, it is preferable that the guiding unit prompts the driver of the vehicle to operate the device when the ratio of the section in which the device is calculated calculated by the ratio calculating unit is less than a predetermined value.

It is possible to prompt the vehicle driver to operate the device more when the ratio of operating is small.

  Or it is suitable for a guidance means to display to the driver | operator of a vehicle the ratio of the area which the apparatus which the ratio calculation means calculated was operating by at least one of an image and an audio | voice.

  According to this configuration, since the guidance unit displays the ratio of the section in which the device calculated by the ratio calculation unit is operating to the driver of the vehicle by at least one of an image and a sound, It is possible for the driver to operate the apparatus at a more appropriate rate.

It is the table | surface which showed the determination conditions of eco-SW use. It is a flowchart which shows the procedure of eco-SW use running diagnosis.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the in-vehicle device 10 according to the present embodiment is mounted on a vehicle and detects an operating state of a device that controls the vehicle so as to perform eco-driving in response to an operation of the driver of the vehicle. It is. Specifically, the device that controls the vehicle to perform eco-driving in response to the driver's operation means that the hazardous substance discharged from the vehicle is reduced when the driver operates the eco-switch and the predetermined driving is performed. It is a device that performs an “eco-driving mode” for controlling the vehicle to make eco-driving so that the amount of fuel consumption relative to the travel distance of the vehicle in the stroke is reduced.

  As shown in FIG. 1, in the in-vehicle device 10, a vehicle LAN 21, a vehicle sensor 22, a camera 23, and an in-vehicle HMI (Human Machine Interface) 40 are connected to the fuel-saving driving diagnosis device 30. The fuel-saving driving diagnosis device 30 includes an input interface unit 31, an environmental driving diagnosis unit 32, an advice generation unit 33, an output interface unit 34, and a wireless communication unit 35.

  The input interface unit 31 is for receiving vehicle information such as in-vehicle LAN information from the vehicle LAN 21, vehicle sensor information from the vehicle sensor 22, and camera video from the camera 23. The in-vehicle LAN information from the vehicle LAN 21 and the vehicle sensor information from the vehicle sensor 22 include the integrated value (travel distance) of the vehicle speed pulse signal detected from the vehicle speed sensor, and the driver enters the eco driving mode using the eco SW. Information about whether or not it is set is included.

  The environmental driving diagnosis section 32 is for diagnosing and quantifying the environmental driving operation and the device operation of the driver. The advice generation unit 33 is for generating advice on environmental driving operation and device operation to the driver.

  The output interface unit 34 uses the advice generated by the advice generation unit 33, the environmental operation operation quantified by the environmental operation diagnosis unit 32, and the operation of the device by the display 41, the audio 42 and the sensor 43 of the in-vehicle HMI 40. In order to guide the driver to environmental driving and teach the driver about environmental driving.

  The wireless communication unit 35 is for transmitting vehicle information collected by the input interface unit 31 and information related to environmental driving diagnosis quantified by the driving diagnosis unit 32 to the center 50. The wireless communication unit 35 is for receiving data processed by the center 50.

  The center 50 includes a center DB 60. The center DB 60 is for storing driving diagnosis data 61 and vehicle information data 62 collected by the in-vehicle device 10. The center 50 is also for creating WEB content and the like using the driving diagnosis data 61 and the vehicle information data 62 stored in the center DB 60.

  Hereinafter, the operation of the in-vehicle device 10 of the present embodiment will be described. As shown in FIG. 2, the environmental driving diagnosis unit 32 has information on the vehicle speed pulse signal obtained by the input interface unit 31 and whether the driver has set the eco driving mode using the eco SW. Vehicle information such as information is detected (S11).

  Based on the acquired vehicle information, the environmental driving diagnosis unit 32 determines “use” when the vehicle is using the eco driving mode, and determines “not used” otherwise (S12). When the vehicle determines that the eco-driving mode is “use”, the environmental driving diagnosis unit 32 determines the travel distance of the predetermined time as “cumulative travel distance using eco-drive mode” at every predetermined eco-drive mode use determination timing. (S13). In addition, the environmental driving diagnosis unit 32 calculates the ratio of the “eco-driving mode use travel distance cumulative” to the “travel distance cumulative total” that is the entire travel distance of the vehicle.

  Hereinafter, the operation relating to the use determination of the eco-drive mode will be specifically described in detail. In addition, it is assumed that the use determination of the eco-driving mode is triggered by the triggering condition that the environmental driving diagnosis unit 32 determines that the eco-SW usage determination timing is every 100 msec.

  As shown in FIG. 4, the environmental driving diagnosis unit 32 calculates the travel distance of the vehicle for 100 msec according to the following procedure. That is, the environmental driving diagnosis unit 32 detects the integrated value of the vehicle speed pulse signal from the vehicle information every 100 msec (S21), and the environmental driving diagnosis unit 32 detects the vehicle speed pulse signal integrated value detected last time (100 msec before). Then, the “travel distance between 100 msec” is calculated from the difference from the current vehicle speed pulse signal integrated value (S23).

  Further, the environmental operation diagnosis unit 32 accumulates “travel distance for 100 msec” as “total travel distance for 1 Trip (updated for 100 msec)” every 100 msec after the ignition switch is turned on.

  As shown in FIG. 4, the environmental driving diagnosis unit 32 calculates the use determination of the eco SW according to the following procedure. That is, the environmental driving diagnosis unit 32 detects the eco SW signal from the vehicle information at every eco SW use determination timing (100 msec) (S21). As shown in the table of FIG. 3, the environmental operation diagnosis unit 32 determines “1: Eco SW is used” when the determination condition for using the Eco SW is satisfied, that is, when the Eco SW is ON (S22). ). On the other hand, as shown in the table of FIG. 3, the environmental operation diagnosis unit 32 determines that “0: no eco-SW is used” when the determination condition for no eco-SW is satisfied, that is, when the eco-SW is OFF. (S22). When it is determined that “1: Eco SW is used” (S22), the environmental driving diagnosis unit 32 adds “travel distance between 100 msec” to “cumulative travel distance using Eco SW” for each eco SW use timing (100 msec). (S23). Furthermore, the environmental driving diagnosis unit 32 calculates the ratio of “eco-SW use travel distance cumulative” to “travel distance cumulative” that is the entire travel distance of the vehicle.

  Returning to FIG. 2, the advice generation unit 33 uses the “eco-driving mode use mileage accumulation” (“eco-SW use mileage accumulation”) and the “travel distance accumulation”, and does not use the eco-drive mode. Alternatively, for the driver whose ratio of “eco-drive mode use travel distance” to “total travel distance” is equal to or less than the threshold value, advice that encourages the use of the eco-drive mode is generated (S14). In addition, the output interface unit 34 displays the advice generated by the advice generation unit 33 to the driver by the in-vehicle HMI 40, and uses the “eco-driving mode use travel distance total” and the “travel distance total” to display “travel distance”. The ratio of “Eco-driving mode use mileage total” to “Total” is displayed to the driver with a gauge on the display 41 of the in-vehicle HMI 40 as the usage degree of the eco-driving mode, or the music output from the audio 42 is changed according to the usage degree (S14).

  Vehicle information collected by the input interface unit 31 and information related to environmental driving diagnosis quantified by the driving diagnosis unit 32 are transmitted to the center 50 by the wireless communication unit 35. The center 50 creates web contents and the like using the driving diagnosis data 61 and the vehicle information data 62 stored in the center DB 60. The wireless communication unit 35 receives the content, and the in-vehicle HMI 40 causes the in-vehicle HMI 40 to display the content.

  In the present embodiment, the driving diagnosis unit 32 detects the operating state of the eco-driving mode mounted on the vehicle, and the eco-driving mode is detected for the entire travel of the vehicle based on the detected operating state of the eco-driving mode. Since the ratio of the travel stroke that has been operating is calculated, it is possible to more appropriately calculate the ratio at which the eco-operation mode mounted on the vehicle is operating, regardless of the behavior of the vehicle. In other words, as a result, a diagnosis that accurately reflects the presence or absence of the driver's consciousness trying to operate the eco-driving mode becomes possible. For this reason, it becomes possible to make a driver | operator confirm the consciousness to own eco-driving correctly.

  Particularly in the present embodiment, the eco-driving mode controls the vehicle so that harmful substances discharged from the vehicle are reduced in response to the operation of the driver of the vehicle. It is possible to more appropriately calculate the ratio of operating the eco-operation mode that reduces the harmful substances emitted.

  Further, in the present embodiment, the eco-driving mode is for controlling the vehicle so that the fuel consumption with respect to the travel distance of the vehicle in a predetermined travel stroke is reduced in response to the operation of the driver of the vehicle. Regardless of the behavior, it is possible to more appropriately calculate the rate at which the device that reduces fuel consumption is operating.

  Further, in the present embodiment, the advice generation unit 33, the output interface unit 34, and the in-vehicle HMI 40 provide the vehicle driver with an eco-friendly ratio based on the ratio of travel distances in the eco driving mode calculated by the driving diagnosis unit 32. In order to prompt the user to operate the driving mode, it becomes possible for the vehicle driver to operate the eco driving mode at a more appropriate ratio in accordance with the ratio at which the eco driving mode is operating.

  In particular, in the present embodiment, the advice generation unit 33, the output interface unit 34, and the in-vehicle HMI 40 are configured so that the vehicle travels when the ratio of the travel distance in the eco driving mode calculated by the driving diagnosis unit 32 is less than a predetermined value. Therefore, it is possible to urge the driver of the vehicle to operate the eco driving mode more when the ratio of the eco driving mode operating is small.

  Further, in the present embodiment, the advice generation unit 33, the output interface unit 34, and the in-vehicle HMI 40 calculate the ratio of the travel distance that has been operated in the eco driving mode calculated by the driving diagnosis unit 32 based on at least one of an image and a sound. Therefore, the eco-driving mode can be operated at a more appropriate ratio for the vehicle driver by the image or the sound.

  Even if the vehicle is equipped with a device that automatically enters eco-driving mode, in order to use the device, the driver uses the function by turning on the eco switch, etc. There must be. Even if the vehicle is in an eco-driving mode in which eco-driving is performed by automatic control, generally using the eco-driving mode necessarily places a burden on the driver. However, simply notifying the instantaneous fuel consumption meter and the average fuel consumption is affected by the driving environment and the like, so the driver does not know the effect of eco driving by using the eco driving mode. In addition, since the driver does not finally understand the effect of the eco driving mode, there is a possibility that the driver does not use the eco driving mode.

  That is, in order to continue eco-driving, it is necessary to improve the driver's awareness of eco-driving, and in order to continue the driver's awareness of eco-driving, it is necessary to realize the effect of eco-driving. However, since the fuel efficiency information such as the instantaneous fuel efficiency meter and the average fuel efficiency is affected by the driving environment and the like, it is difficult for the driver to understand the effect of eco-driving.

  On the other hand, in the present embodiment, the environmental driving diagnosis unit 32 can digitize the device operation for eco-driving, and thereby inform the driver of the degree of execution of eco-driving through the in-vehicle HMI 40. As a result, the driver strives to increase the degree of eco-driving, leading to fuel-saving driving.

  Moreover, in this embodiment, the environmental driving | operation diagnosis part 32 can provide the advice for encouraging a driver | operator to eco-driving by digitizing the apparatus operation regarding eco-driving. As a result, the driver can be guided to perform eco-driving, which leads to fuel-saving driving.

  Furthermore, in the present embodiment, the environmental operation diagnosis unit 32 digitizes device operations related to environmental operation, and the center 50 creates a database, whereby the driver's device operation status can be grasped. In addition, in this embodiment, it is also possible to grasp the driver's implementation and non-execution factors of eco-driving by associating with vehicle position information (travel route, destination, behavioral purpose estimation, road information) and weather. it can. In the present embodiment, advice on eco-driving can be provided to the driver at an appropriate timing using these pieces of information.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
