As shown in FIG. 1, a vehicle drive device 8 includes a transaxle case 12 (hereinafter referred to as “case 12”) as a non-rotating member attached to a vehicle body, a generally known automobile gasoline engine or diesel engine. An engine 14, a first motor MG1 functioning as a differential motor, a second motor MG2 functioning as a traveling motor, a first planetary gear device 20, and a second planetary gear device 22. The power of the engine 14 or the second electric motor MG2 is supplied from the output gear 24 that rotates integrally with the ring gears R1 and R2 of the first planetary gear device 20 and the second planetary gear device 22 to the counter gear pair 32 including the output gear 24, final It is transmitted to the pair of drive wheels 40 through the gear pair 34, the differential gear device 36, the pair of axles 38 and the like in order (see FIG. 2).

  The first planetary gear device 20 includes a first carrier CA1 connected to the engine 14, a first sun gear S1 connected to the first electric motor MG1, and a first ring gear R1 that rotates integrally with the output gear 24. . The second planetary gear unit 22 includes a second carrier CA2 that is connected to the case 12 and cannot rotate, a second sun gear S2 that is connected to the second electric motor MG2, and a second ring gear R2 that rotates together with the output gear 24. It has.

  Each of the first motor MG1 and the second motor MG2 is a so-called motor generator having both a generator (generator) function and a motor (engine) function, and is, for example, a three-phase synchronous motor generator. The first motor MG1 and the second motor MG2 are each electrically connected to the power storage device 56 via an inverter 54 (see FIG. 2), and the first motor MG1, the second motor MG2, and the power storage device 56 are mutually connected. The power can be exchanged. The power storage device 56 is, for example, a battery (secondary battery) such as a lead storage battery or a capacitor.

That is, the vehicle 6 can perform engine traveling including the engine 14 as a driving force source for traveling, or motor traveling in which the driving power source for traveling is only the second electric motor MG2.

  Further, when coasting, which is inertial traveling with the acceleration operation canceled, for example, the electronic control device 60 performs inertial traveling control when the vehicle state satisfies a predetermined control execution condition. The inertial running control means that the first motor MG1 is idled to cut off the power transmission between the engine 14 and the drive wheels 40, the engine 14 is stopped, and the second electric motor MG2 is idled to run inertially.

  FIG. 2 is a diagram exemplifying signals input to the electronic control device 60 that is a vehicle control device for controlling the vehicle 6, and the main part of the control function provided in the electronic control device 60 will be described. It is a functional block diagram for The electronic control device 60 includes a so-called microcomputer. For example, as shown in FIG. 2, various signals are supplied to the electronic control device 60 from the respective sensors 42, 46, 48, 50, 52 which are vehicle sensors. Specifically, a signal from the accelerator opening sensor 42 that represents the accelerator opening Acc that is the operation amount of the accelerator pedal, a signal from the foot brake sensor 46 that represents the depression amount of the foot brake pedal, and a wheel provided on each wheel A signal from the wheel brake sensor 48 representing the mechanical vehicle braking force generated by the brake device, a signal from the acceleration sensor 50 representing the vehicle acceleration in the longitudinal direction of the vehicle 6, a signal from the vehicle speed sensor 52 representing the vehicle speed V, and a power storage device A signal from the power storage device 56 representing the remaining charge (charged state) SOC (unit: Wh, for example) of 56, and from the air conditioner 44 representing the operating state (on / off) of the air conditioner 44 that is the air conditioner in the passenger compartment Each signal is supplied to the electronic control unit 60.

  As shown in FIG. 2, the electronic control unit 60 has a function of executing known navigation control, and a map database (map DB) 62 in which road map information used for executing the navigation control is stored. It has. The map database 62 is composed of a non-volatile storage device such as a hard disk drive (HDD). FIG. 3 is a diagram for explaining how roads are stored in the road map information. FIG. 3A shows a schematic diagram of an actual road, and FIG. A node ND and a link Lnk representing the road stored as part of the road map information are shown. As shown in FIG. 3, an actual road is represented by links Lnk as a plurality of sections divided by a plurality of nodes ND and connecting between the nodes ND in the road map information. That is, the link Lnk corresponds to the traveling road of the present invention as a section of the road. For each link Lnk, a link ID (road number) is determined as shown in FIG. In addition, for each link ID, the start point and end point coordinates defined by the node ND, the average curvature radius and road length and road gradient as travel path information, road types such as general roads, expressways and one-way streets, intersections and Information at each node ND such as a passing point on a straight road is stored in the map database 62, and information for each link ID is also included in the road map information.

  The display device 64 in FIG. 2 is an image display device such as a liquid crystal display device provided so that the driver can easily see in the passenger compartment, and displays an image in accordance with an output instruction from the electronic control device 60. For example, the display device 64 functions as an output device in the navigation control of the electronic control device 60, and the vehicle position specified by the navigation control and the road map around the vehicle position extracted from the road map information. The traffic information is displayed, and the display image is sequentially updated in accordance with the output instruction from the electronic control unit 60.

  Next, the main part of the control function of the present embodiment will be described with reference to FIG. As shown in FIG. 2, the electronic control unit 60 includes a travel control unit 70 as a travel control unit, a vehicle position specifying unit 72 as a vehicle position specifying unit, a learning unit 74 as a learning unit, and a display. And a display unit 76 as means.

  The traveling control unit 70 executes the inertial traveling control when the vehicle state satisfies a predetermined control execution condition. This inertial traveling control is a traveling control that is executed when the accelerator pedal is released when the accelerator pedal is released, that is, when the acceleration operation is released, and is executed for the purpose of improving the fuel consumption of the vehicle 6. In addition, the control execution condition is experimentally set in advance so as to suppress the uncomfortable feeling generated for the driver and to improve the fuel consumption of the vehicle 6. For example, the control execution condition is a condition that is satisfied when the vehicle speed V, the turning radius of the vehicle 6, the gradient of the traveling road surface, and the remaining charge SOC of the power storage device 56 are within predetermined ranges. The predetermined range is changed according to whether 44 is turned on or off. Therefore, the vehicle state that the traveling control unit 70 compares with the control execution condition specifically includes the vehicle speed V that defines the control execution condition, the turning radius of the vehicle 6, the gradient of the traveling road surface, and the remaining charge of the power storage device 56. This is indicated by the SOC and the operating state of the air conditioner 44. Moreover, the traveling control unit 70 performs various traveling controls other than the inertial traveling control. For example, pre-reading information obtained by predicting the previous vehicle state based on the history information DThis may be acquired from the learning unit 74, and traveling control may be performed using the pre-reading information. In this embodiment, the fuel consumption is expressed by a travel distance per unit fuel consumption (unit: km / L, for example), and an improvement in fuel efficiency means a longer travel distance per unit fuel consumption. Conversely, a decrease (deterioration) in fuel consumption means that the travel distance per unit fuel consumption is shortened. The fuel consumption may be expressed by the fuel consumption rate of the vehicle as a whole (= fuel consumption / drive wheel output). If so, the improvement in fuel consumption is the fuel consumption of the vehicle as a whole. On the other hand, the reduction in fuel consumption means that the fuel consumption rate of the vehicle as a whole increases.

  The own vehicle position specifying unit 72 uses the GNSS (Global Navigation Satellite System) and each detection information detected by the vehicle sensor (acceleration, yaw rate, wheel speed, steering angle, etc. of the vehicle 6) to determine the position of the vehicle 6. The vehicle position, the vehicle speed V, and the attitude of the vehicle 6 are sequentially calculated. And the said vehicle position is collated with the said road map information, Link ID of the traveling path (link Lnk) which the vehicle 6 is drive | working now, and the advancing direction in the traveling path are specified. In short, map matching performed by a known navigation system is performed.

  The learning unit 74 sequentially acquires own vehicle position information such as the own vehicle position, the vehicle speed V, the link ID of the currently traveling road, and the traveling direction of the vehicle 6 from the own vehicle position specifying unit 72. In addition, vehicle information such as the remaining charge SOC of the power storage device 56, the fuel injection amount of the engine 14, the engine rotational speed Ne, the accelerator opening degree Acc, and the foot brake pedal depression amount is sequentially obtained from each sensor and the like. doing. Then, the learning unit 74, every time the traveling vehicle 6 passes through each link Lnk corresponding to one section of the road, that is, every time the vehicle 6 reaches the node ND at the end point of the link Lnk, The travel data on the link Lnk that has traveled is stored in the learning database 66 in association with the link Lnk. That is, the learning control is executed to accumulate the travel data obtained as the vehicle 6 travels on the link Lnk (travel path) as the history information DThis (see FIG. 4). The learning database (learning DB) 66 is for storing the travel data, and is configured by a non-volatile storage device such as the HDD. The travel data stored as the history information DThis will be described with reference to FIG.

  FIG. 4 is a diagram illustrating history information DThis obtained by accumulating the travel data. As shown in FIG. 4, in the history information DThis, the vehicle speed V, the charge amount ΔSOC (unit: Wh, for example) charged in the power storage device 56, the number of travels NMrun, the number of control executions NMexc of the inertial travel control, the inertia The travel data including the section fuel consumption FEsc at the time of executing the travel control and whether or not the inertial travel control is forcibly terminated is divided into the forward path or the return path indicating the traveling direction of the vehicle 6 and is associated with each link Lnk for each link ID. It is remembered. More specifically, the vehicle speed V of the history information DThis is stored by averaging the average vehicle speed for each vehicle travel in the link Lnk (travel path) of the corresponding link ID. Further, the charge amount ΔSOC for each vehicle travel can be calculated as a difference between the remaining charge SOC of the power storage device 56 at the start point of the link Lnk and the remaining charge SOC of the power storage device 56 at the end point of the link Lnk. The charge amount ΔSOC of the history information DThis is stored by averaging the charge amount ΔSOC for each vehicle run. Further, the travel count NMrun of the history information DThis is the number of times the vehicle 6 travels the link Lnk of the corresponding link ID. Further, the control execution number NMexc of the history information DThis is the number of times that the inertial traveling control is normally performed when the vehicle 6 travels on the link Lnk of the corresponding link ID. That the inertial running control is normally executed means that the inertial running control is instantaneously executed and the case where the inertial running control is forcibly terminated by fail-safe or the like is excluded. Further, the section fuel consumption FEsc of the history information DThis is stored by averaging the section fuel consumption FEsc for each vehicle travel when the inertial traveling control is normally executed. The presence / absence of forced termination of inertial traveling control in the history information DThis stores the presence / absence of forced termination in the latest vehicle traveling.

  In addition to executing the learning control described above, the learning unit 74 includes a display content determination unit 78 that determines the display content related to the inertia running control that is the basis of the image displayed on the display device 64 for each link Lnk. . In order to determine the display content, the display content determination unit 78 as the display content determination means first determines the road map information based on the current position of the vehicle 6 obtained from the vehicle position specifying unit 72, that is, the vehicle position. From this, the target link LNKi, which is the target link Lnk for determining the display content related to the inertial running control, is determined. For example, the display content determination unit 78 determines the link Lnk within the predetermined range RGi based on the vehicle position as the target link LNKi. Specifically, on the condition that the link Lnk existing on the road from the vehicle position and existing within a predetermined distance corresponding to the predetermined range RGi is the link Lnk displayed on the display device 64. All are determined as the target link LNKi. Accordingly, there are usually a plurality of target links LNKi. The prescribed distance is experimentally set in advance to such an extent that the driver can recognize that it is around the vehicle position.

  When determining the target link LNKi, the display content determination unit 78 provides various flags for each of the target links LNKi for the sake of convenience in determining the display content related to the inertia traveling control. Specifically, for each of the target links LNKi, a completion flag FLG_end indicating that the determination of the display content is completed, and the inertial traveling control is executed on the target link LNKi in the current vehicle state. Control execution estimation flag FLG_ok indicating that the inertial running control is estimated to be executed on the target link LNKi if a predetermined deceleration is performed. FLG_spddwn, acceleration control execution estimation flag FLG_spdup indicating that the inertial running control is estimated to be executed on the target link LNKi if a predetermined speed increase is performed, and the inertia if the air conditioner 44 is turned off An air conditioner off time control execution estimation flag FLG_acoff is provided which indicates that the traveling control is estimated to be executed on the target link LNKi. At this time, the values of the flags FLG_end, FLG_ok, FLG_spddwn, FLG_spdup, and FLG_acoff are all zero, which is an initial value. When the display content determination unit 78 provides the flags FLG_end, FLG_ok, FLG_spddwn, FLG_spdup, and FLG_acoff, the display content determination unit 78 performs display content determination control for determining the display content related to the inertial traveling control for each target link LNKi. The completion flag FLG_end of the target link LNKi for which the decision control has been completed is switched from 0 to 1. Accordingly, when the completion flag FLG_end of all the target links LNKi becomes 1, it means that the determination of the display content is completed.

  The display content determination control of this embodiment will be described. The display content determination unit 78 first sets a completion flag FLG_end to 0 in order to determine the display content related to the inertial travel control for all target links LNKi. One target link LNKi is selected from the existing target links LNKi. The selected target link LNKi is referred to as a selected link LNKs. When the display content determination unit 78 determines the selected link LNKs, the individual state such as the vehicle speed V, the remaining charge SOC of the power storage device 56, the on / off of the air conditioner 44, and the accelerator opening Acc is determined from the history information DThis. Based on the current vehicle state represented by the parameters, the vehicle state when the vehicle 6 reaches the selected link LNKs, that is, the estimated vehicle state in the selected link LNKs is estimated. Specifically, the estimated vehicle state in the selected link LNKs is estimated by estimating each of the state parameters in the selected link LNKs according to an estimation method predetermined for each individual state parameter. For example, the vehicle speed V constituting the estimated vehicle state is the vehicle speed V corresponding to the link ID of the selected link LNKs with respect to the vehicle speed V corresponding to the link ID of the link Lnk on which the vehicle 6 is currently traveling in the history information DThis. The ratio is calculated, and the current vehicle speed V is calculated as changing at the same ratio as the calculated ratio of the vehicle speed V. Further, the remaining charge SOC of the power storage device 56 constituting the estimated vehicle state is the value of all the links Lnk constituting the route from the link Lnk where the vehicle 6 is currently traveling to the selected link LNKs in the history information DThis. The charge amount ΔSOC corresponding to the link ID is integrated, and the current remaining charge SOC is calculated as changing by the integrated charge amount ΔSOC. Further, the operating state (ON or OFF) of the air conditioner 44 constituting the estimated vehicle state is estimated as the current operating state continues as it is. The turning radius of the vehicle 6 constituting the estimated vehicle state is estimated as the vehicle 6 turning at the average curvature radius of the selected link LNKs obtained from the road map information. Further, the accelerator opening Acc constituting the estimated vehicle state is estimated to be the accelerator off regardless of the accelerator opening Acc because the accelerator off is an indispensable condition for executing the inertia traveling control.

  When the display content determination unit 78 thus estimates the estimated vehicle state in the selected link LNKs, whether or not the inertial traveling control is executed under the estimated vehicle state, that is, the estimated vehicle state is It is determined whether or not a control execution condition is satisfied. As a result of the determination, when the estimated vehicle state satisfies the control execution condition, the control execution estimation flag FLG_ok of the selected link LNKs is switched from 0 to 1. In short, if the display content determination unit 78 is predicted to execute the inertial traveling control based on the current vehicle state without applying a predetermined change described later to the current vehicle state, The control execution estimation flag FLG_ok of the selected link LNKs is switched from 0 to 1. After the setting of the control execution estimation flag FLG_ok is switched, the completion flag FLG_end of the selected link LNKs is switched from 0 to 1.

  On the other hand, when the estimated vehicle state does not satisfy the control execution condition, the display content determination unit 78 assumes the case where several types of predetermined changes are added to the current vehicle state, and then performs the estimation. It is determined whether the vehicle state satisfies the control execution condition. Specifically, assuming a vehicle state in which a predetermined change in which the vehicle speed V is reduced within a predetermined deceleration amount is added to the current vehicle state, estimation is performed again based on the assumed vehicle state. It is determined whether the estimated vehicle state satisfies the control execution condition. As a result of the determination, if the estimated vehicle state estimated anew satisfies the control execution condition, the deceleration-time control execution estimation flag FLG_spddwn of the selected link LNKs is switched from 0 to 1. In short, when the display content determination unit 78 predicts that the inertial running control will be executed if a predetermined change that reduces the vehicle speed V within the predetermined deceleration amount is applied to the current vehicle state. In this case, the control execution estimation flag FLG_spddwn during deceleration of the selected link LNKs is switched from 0 to 1. In addition, the display content determination unit 78 assumes a vehicle state in which a predetermined change that increases the vehicle speed V within a predetermined acceleration amount range is added to the current vehicle state, and sets the assumed vehicle state. It is determined whether or not the estimated vehicle state estimated anew based on the above condition satisfies the control execution condition. As a result of the determination, if the estimated vehicle state estimated anew satisfies the control execution condition, the control execution estimation flag FLG_spdup at the time of acceleration of the selected link LNKs is switched from 0 to 1. In short, the display content determination unit 78 is predicted to execute the inertial running control if a predetermined change that increases the vehicle speed V within the predetermined acceleration amount is added to the current vehicle state. In this case, the acceleration control execution estimation flag FLG_spdup for the selected link LNKs is switched from 0 to 1. Further, the display content determination unit 78 assumes a vehicle state in which a predetermined change that the air conditioner 44 is turned off if the air conditioner 44 is turned on in the current vehicle state is added to the current vehicle state. It is determined whether the estimated vehicle state estimated anew based on the assumed vehicle state satisfies the control execution condition. As a result of the determination, when the estimated vehicle state estimated anew satisfies the control execution condition, the control execution estimation flag FLG_acoff when the air conditioner is off for the selected link LNKs is switched from 0 to 1. In short, if it is predicted that the inertial running control will be executed if a predetermined change that the air conditioner 44 is turned off is added to the current vehicle state, the display content determination unit 78 sets the selected link LNKs. The control execution estimation flag FLG_acoff when the air conditioner is off is switched from 0 to 1. In this way, even when it is determined to switch the series of flags FLG_spddwn, FLG_spdup, FLG_acoff, the completion flag FLG_end of the selected link LNKs is switched from 0 to 1. The deceleration amount and the acceleration amount used when assuming the vehicle state are experimentally determined in advance so as to correspond to a slight vehicle operation performed by the driver so as to execute the inertial traveling control. Yes.

  When the completion flag FLG_end is switched to 1 for one selected link LNKs as described above, one target link LNKi is selected again from the target links LNKi whose completion flag FLG_end is set to 0 again. Selected as LNKs. Then, the display content determination control of this embodiment is repeatedly executed until the completion flag FLG_end of all the target links LNKi becomes 1.

  The display unit 76 displays the vehicle position and a map including roads around the vehicle position on the display device 64 in the same manner as a known navigation system, and sequentially updates the display image of the display device 64. Further, the information indicated by the flags FLG_ok, FLG_spddwn, FLG_spdup, and FLG_acoff determined by the display content determination unit 78 is displayed on the display device 64 in association with the target link LNKi by changing the pattern or color representing the link Lnk. . An example of the display is shown in FIG. FIG. 5 is a display example in which roads are displayed in a plane. For example, on the display device 64, the predetermined change that is assumed to be applied to the current vehicle state by a button operation by the driver is any of increase / decrease of the vehicle speed V, acceleration operation, or change of the operating state of the air conditioner 44 In FIG. 5, the increase / decrease of the vehicle speed V is selected, and the selection image 88 indicates this. In FIG. 5, the own vehicle image 90 is an image representing the vehicle 6 and shows the own vehicle position and traveling direction, the node ND is extracted and displayed, and the solid line 92 is a series of the links Lnk. Shows the road. In the host vehicle image 90, the side protruding in the longitudinal direction of the solid line 92 on which the host vehicle image 90 is disposed indicates the traveling direction of the vehicle 6. The display device 64 displays a first road image 94, a second road image 96, and a third road image 98 indicating a predetermined section of the road. The first road image 94 is subjected to the inertial running control. It is an image representing a predicted travel route, that is, an image representing the target link LNKi in which the control execution estimation flag FLG_ok is set to 1. In addition, the second road image 96 connected in series to the first road image 94 may have the inertia if the predetermined change that reduces the vehicle speed V within the predetermined deceleration amount is applied to the current vehicle state. It is an image representing a travel route predicted to execute travel control, that is, an image representing the target link LNKi in which the deceleration-time control execution estimation flag FLG_spddwn is set to 1. Further, the third road image 98 connected in series to the first road image 94 can be obtained by adding a predetermined change that increases the vehicle speed V within a range within the predetermined acceleration amount to the current vehicle state. It is an image representing a travel route predicted to perform inertial travel control, that is, an image representing the target link LNKi in which the acceleration control execution estimation flag FLG_spdup is set to 1. The first road image 94, the second road image 96, and the third road image 98 all have a band shape thicker than the solid line 92, and are displayed in different patterns or colors.

  If a predetermined change that is assumed to be applied to the current vehicle state is switched to, for example, an operation state change of the air conditioner 44 by a driver's button operation or the like, the display unit 76 displays the selection image 88. , Switch to indicate that “air conditioner” is selected. Then, the first road image 94 is displayed as it is as in FIG. 5, but the second road image 96 and the third road image 98 are not displayed. Instead, the display unit 76 displays a predetermined belt-like road that represents a travel path that is predicted to perform the inertial travel control if a predetermined change that the air conditioner 44 is turned off is applied to the current vehicle state. An image, that is, a predetermined belt-shaped road image representing the target link LNKi in which the control execution estimation flag FLG_acoff when the air conditioner is off is set to 1 is displayed.

  5 is a display example in which roads are displayed in a plane, the display unit 76 may display the roads on the display device 64 in a bird's-eye view as shown in FIG. For example, in FIG. 6, the vehicle 6 is represented by the own vehicle image 100. Then, the image 104 representing the target link LNKi in which the control execution estimation flag FLG_ok is set to 1 and the deceleration-time control execution estimation flag FLG_spddwn to 1 are superimposed on the image 102 of the road constituting the course of the vehicle 6. An image 106 representing the set target link LNKi is displayed in series. The images 102, 104, and 106 are displayed in different predetermined patterns or colors, respectively.

  FIG. 7 illustrates the main part of the control operation of the electronic control unit 60, that is, the control operation for storing the travel data as the history information DThis and displaying information on the inertia travel control obtained from the history information DThis. For example, the flowchart is repeatedly executed with an extremely short cycle time of about several milliseconds to several tens of milliseconds. The control operation shown in FIG. 7 is executed alone or in parallel with other control operations.

  First, in step (hereinafter, “step” is omitted) SA1 in FIG. 7, the vehicle position, the vehicle speed V, the attitude of the vehicle 6, and the like, which are the positions of the vehicle 6, are sequentially calculated. Then, the vehicle position is collated with the road map information, and the link ID of the travel path (link Lnk) on which the vehicle 6 is currently traveling and the traveling direction on the travel path are specified. So-called map matching is performed. After SA1, the process proceeds to SA2. SA1 corresponds to the vehicle position specifying unit 72.

  In SA2 corresponding to the learning unit 74, it is determined from the own vehicle position calculated in SA1 whether the vehicle 6 has reached the node ND at the end point of each link Lnk. If the determination of SA2 is affirmative, that is, if the vehicle 6 has reached the node ND at the end of the link Lnk, the process proceeds to SA3. On the other hand, if the determination at SA2 is negative, the operation goes to SA4.

  In SA3 corresponding to the learning unit 74, the travel data on the link Lnk that has traveled, that is, the travel data on the link Lnk whose end point is the node ND determined that the vehicle 6 has reached in SA2 is It is stored in the learning database 66 in association with the link Lnk. That is, the travel data obtained by the vehicle 6 traveling on the link Lnk is accumulated as history information DThis. After SA3, the process proceeds to SA4.

  In SA4 corresponding to the display content determination unit 78, the target link LNKi is determined. For example, one or more links Lnk within a predetermined range RGi based on the vehicle position specified in SA1 are determined as the target links LNKi. A plurality of flags FLG_end, FLG_ok, FLG_spddwn, FLG_spdup, and FLG_acoff set to initial values (= 0) are provided for each of the target links LNKi. After SA4, the process proceeds to SA5.

  In SA5 corresponding to the display content determination unit 78, it is determined whether or not the completion flag FLG_end of all the target links LNKi is 1. The fact that the completion flag FLG_end of all the target links LNKi is 1 indicates that the determination of the display content related to the inertia traveling control is completed for all the target links LNKi. If the determination of SA5 is affirmative, that is, if the completion flag FLG_end of all the target links LNKi is 1, the process proceeds to SA8. On the other hand, if the determination at SA5 is negative, the operation goes to SA6.

  In SA6 corresponding to the display content determination unit 78, one target link LNKi is selected as the selected link LNKs from among the target links LNKi whose completion flag FLG_end is set to 0. After SA6, the process proceeds to SA7.

  In SA7, the flowchart of FIG. 8 is executed. FIG. 8 is a flowchart showing a subroutine executed in SA7. All the steps in FIG. 8 correspond to the display content determination unit 78.

  In SB1 of FIG. 8, the current vehicle state represented by individual state parameters such as vehicle speed V, remaining charge SOC of power storage device 56, air conditioner 44 on / off, and accelerator opening Acc is recognized. After SB1, the process proceeds to SB2.

  In SB2, the estimated vehicle state in the selected link LNKs selected in SA6 of FIG. 7 is estimated based on the current vehicle state recognized in SB1 from the history information DThis. After SB2, the process proceeds to SB3.

  In SB3, it is determined whether or not the inertial running control is executed under the estimated vehicle state estimated in SB2, that is, whether or not the estimated vehicle state satisfies the control execution condition. When the determination of SB3 is affirmed, that is, when the estimated vehicle state satisfies the control execution condition, the process proceeds to SB4. On the other hand, if the determination at SB3 is negative, the operation proceeds to SB5.

  In SB4, the control execution estimation flag FLG_ok of the selected link LNKs is switched from 0 to 1. After SB4, the process proceeds to SB11.

  In SB5, it is determined whether or not the inertial running control is predicted to be executed if a predetermined change that reduces the vehicle speed V within the predetermined deceleration amount is applied to the current vehicle state. The If the determination of SB5 is affirmed, that is, if the predetermined change of decreasing the vehicle speed V within the predetermined deceleration amount is applied to the current vehicle state, the inertial traveling control is predicted to be executed. If so, the process proceeds to SB6. On the other hand, if the determination at SB5 is negative, the operation proceeds to SB7.

  In SB6, the deceleration execution control execution estimation flag FLG_spddwn of the selected link LNKs is switched from 0 to 1. After SB6, the process proceeds to SB9.

  In SB7, it is determined whether or not the inertial running control is predicted to be executed if a predetermined change of increasing the vehicle speed V within the predetermined acceleration amount is added to the current vehicle state. Is done. When the determination of SB7 is affirmed, that is, when the inertial running control is executed if a predetermined change of increasing the vehicle speed V within the predetermined acceleration amount is added to the current vehicle state. If predicted, the process proceeds to SB8. On the other hand, if the determination at SB7 is negative, the operation proceeds to SB9.

  In SB8, the acceleration control execution estimation flag FLG_spdup of the selected link LNKs is switched from 0 to 1. After SB8, the process proceeds to SB9.

  In SB9, it is determined whether or not the inertial running control is predicted to be executed if a predetermined change that the air conditioner 44 is turned off is added to the current vehicle state. If the determination in SB9 is affirmative, that is, if it is predicted that the inertial running control will be executed if a predetermined change that the air conditioner 44 is turned off is added to the current vehicle state, the process goes to SB10. Move. On the other hand, if the determination at SB9 is negative, the operation proceeds to SB11.

  In SB10, the air conditioner off time control execution estimation flag FLG_acoff of the selected link LNKs is switched from 0 to 1. After SB10, the process proceeds to SB11.

  In SB11, the completion flag FLG_end of the selected link LNKs is switched from 0 to 1. When the setting switching of the completion flag FLG_end in SB11 is completed, the process proceeds to SA5, which is the next step after SA7 in FIG.

  Returning to FIG. 7, in SA8 corresponding to the display unit 76, as shown in FIG. 5, for example, according to the values of the control execution estimation flag FLG_ok, the deceleration control execution estimation flag FLG_spddwn, and the acceleration control execution estimation flag FLG_spdup. Images of roads around the vehicle position including the first road image 94, the second road image 96, and the third road image 98 are displayed on the display device 64 together with the vehicle image 90. Further, if a predetermined change that is assumed to be added to the current vehicle state by a driver's button operation or the like is switched to, for example, an operation state change of the air conditioner 44, A predetermined road image is displayed.

  This embodiment has the following effects (A1) to (A3). (A1) According to the present embodiment, the learning unit 74 obtains the travel data obtained by the vehicle 6 traveling on the link Lnk (travel path) every time the traveling vehicle 6 passes through each link Lnk. Is stored as history information DThis. The display content determination unit 78 controls the selected link LNKs when it is predicted that the inertial traveling control (predetermined traveling control) will be executed based on the current vehicle state from the history information DThis. The execution estimation flag FLG_ok is switched from 0 to 1. The display unit 76 displays the target link LNKi in which the control execution estimation flag FLG_ok is set to 1 on the display device 64 as the first road image 94. That is, the display unit 76 indicates that the inertial traveling control (predetermined traveling control) is predicted to be executed based on the current vehicle state from the history information DThis. The position is displayed on the display device 64 in association with the travel path (link Lnk) within the predetermined range RGi. Therefore, if the driver changes the current vehicle state, the traveling path (link Lnk) that is predicted to execute the inertial traveling control is different and is displayed on the display device 64. The device 60 can present, for example, information to the driver, which can be understood as to what kind of vehicle operation the inertial traveling control is likely to be executed. Then, for example, the driver can drive the vehicle 6 so as to consciously draw out the merit of improving the fuel consumption by the inertial running control. In addition, it is possible to make the driver recognize the traveling in which the inertial traveling control is easily performed, and the driver can easily feel the merit of the inertial traveling control.

  (A2) Also, according to the present embodiment, the display content determination unit 78 may add the predetermined change that reduces the vehicle speed V within the predetermined deceleration amount to the current vehicle state, for example. When traveling control is predicted to be performed, the deceleration-time control execution estimation flag FLG_spddwn of the selected link LNKs is switched from 0 to 1. The display unit 76 displays the target link LNKi in which the deceleration control execution estimation flag FLG_spddwn is set to 1 on the display device 64 as the second road image 96. That is, the display unit 76 predicts that the inertial traveling control (predetermined traveling control) is executed based on the current vehicle state from the history information DThis if the predetermined change is applied to the current vehicle state. Is displayed on the display device 64 in association with the travel path (link Lnk) within the predetermined range RGi. Therefore, since the display device 64 suggests by what kind of vehicle operation the section in which the inertial traveling control is executed can be increased, there is a correlation between whether or not the inertial traveling control can be executed and the vehicle operation. Is easier to understand. In addition, it is possible to give the driver a feeling of executing the inertial running control.

  (A3) Further, according to the present embodiment, the display content determination unit 78 determines the link Lnk based on the current vehicle state from the history information DThis for each target link LNKi that is the link Lnk in the predetermined range RGi. The estimated vehicle state at (selected link LNKs) is estimated. When the estimated vehicle state satisfies the control execution condition of the inertial traveling control (predetermined traveling control), the control execution estimation flag FLG_ok of the selected link LNKs is switched from 0 to 1. In short, it is assumed that the inertial traveling control is predicted to be executed on the selected link LNKs. Therefore, the electronic control unit 60 can clearly determine whether or not the inertial running control is predicted to be executed by using the control execution condition.

  Next, another embodiment of the present invention will be described. In the following description of the embodiments, portions that overlap each other are denoted by the same reference numerals and description thereof is omitted.

  The functional block diagram of the present embodiment is the same as FIG. As shown in FIG. 2, the electronic control device 200 that is the vehicle control device of the present embodiment is similar to the electronic control device 60 of the first embodiment in that the travel control unit 70, the vehicle position specifying unit 72, the learning unit 74, It has. However, unlike the electronic control device 60, the electronic control device 200 includes a display unit 204 instead of the display unit 76, and the learning unit 74 includes a display content determination unit 202 instead of the display content determination unit 78. .

  The display content determination unit 202 as the display content determination unit mainly differs from the display content determination unit 78 of the first embodiment described above in the type of flag to be switched and set. The display content determination unit 202 determines one or more target links LNKi in the same manner as the display content determination unit 78. When the display content determination unit 202 determines the target link LNKi, the display content determination unit 202 sets various flags for each of the target links LNKi. Specifically, for each of the target links LNKi, the completion flag FLG_end, a control execution frequency flag FLG_fcyexc in which a larger value is set as the execution frequency FCYexc of the inertia traveling control is higher, and the inertia traveling control A control execution effect flag FLG_efct in which a larger value is set as the effect is higher is provided. The values of the flags FLG_end, FLG_fcyexc, and FLG_efct at this time are all zero, which is an initial value. When the display content determination unit 202 provides the flags FLG_end, FLG_fcyexc, and FLG_efct, the display content determination control performs display content determination control for determining the display content related to the inertial running control for each target link LNKi, and the display content determination control is completed. The completion flag FLG_end of the target link LNKi is switched from 0 to 1.

  Explaining the display content determination control of the present embodiment, the display content determination unit 202 first sets the completion flag FLG_end to 0 in order to determine the display content related to the inertia traveling control for all the target links LNKi. One target link LNKi is selected from the existing target links LNKi. The selected target link LNKi is referred to as a selected link LNKs. This is the same as the first embodiment. When the display content determining unit 202 determines the selected link LNKs, the display content determining unit 202 reads the travel number NMrun corresponding to the link ID of the selected link LNKs and the control execution number NMexc of the inertial travel control from the history information DThis, Based on the read travel count NMrun and control execution count NMexc, the inertial travel control execution frequency FCYexc (= NMexc / NMrun) in the selected link LNKs is calculated. The display content determination unit 202 sets a larger value to the control execution frequency flag FLG_fcyexc of the selected link LNKs as the calculated execution frequency FCYexc is higher. The execution frequency FCYexc can take a value of 0 to 1 as can be seen from the calculation formula. For example, if the number of control executions NMexc is zero, that is, if the execution frequency FCYexc is zero, the display content determination unit 202 keeps the control execution frequency flag FLG_fcyexc at the initial value (= 0). In addition, the first execution frequency range, the second execution frequency range, and the third execution are successively performed in order from the lower execution frequency FCYexc over the range where the execution frequency FCYexc is greater than zero and less than or equal to 1 (0 <FCYexc ≦ 1). The frequency range, the fourth execution frequency range, and the fifth execution frequency range are experimentally set in advance to set the control execution frequency flag FLG_fcyexc. If the calculated execution frequency FCYexc is within the first execution frequency range, the display content determination unit 202 sets the control execution frequency flag FLG_fcyexc to 1. If the calculated execution frequency FCYexc is within the second execution frequency range, the display content determination unit 202 sets the control execution frequency flag FLG_fcyexc to 2. If the calculated execution frequency FCYexc is within the third execution frequency range, the display content determination unit 202 sets the control execution frequency flag FLG_fcyexc to 3. If the calculated execution frequency FCYexc is within the fourth execution frequency range, the display content determination unit 202 sets the control execution frequency flag FLG_fcyexc to 4. If the calculated execution frequency FCYexc is within the fifth execution frequency range, that is, if the calculated execution frequency FCYexc is higher than the upper limit value of the fourth execution frequency range, the display content determination unit 202 The control execution frequency flag FLG_fcyexc is set to 5. When the display content determination unit 202 sets the control execution frequency flag FLG_fcyexc according to the height of the execution frequency FCYexc as described above, if the control execution frequency flag FLG_fcyexc after the setting is 0, the selected link The LNKs completion flag FLG_end is switched from 0 to 1. On the other hand, when the control execution frequency flag FLG_fcyexc after the setting is not 0, that is, any one of 1 to 5, the display content determination unit 202 switches the control execution effect flag FLG_efct of the selected link LNKs. Set up.

  Specifically, when performing the switching setting of the control execution effect flag FLG_efct, the display content determination unit 202 first quantitatively represents the effect of the inertia running control from the history information DThis. For example, the display content determination unit 202 reads, from the history information DThis, the section fuel consumption FEsc at the time of executing the inertia traveling control corresponding to the link ID of the selected link LNKs. This is because the section fuel consumption FEsc represents the effect of the inertia running control. The reference section fuel consumption FE0sc is experimentally obtained and set in advance for each link Lnk, and the display content determination unit 202 uses the read section fuel consumption FEsc as the reference corresponding to the link ID of the selected link LNKs. Dividing by the section fuel consumption FE0sc, the fuel consumption index value FEind (= FEsc / FE0sc) of the selected link LNKs is calculated. The reason why the fuel efficiency index value FEind is calculated in this way is to obtain an index value that can determine the non-dimensionality of the fuel efficiency because the running resistance that affects the fuel efficiency differs if the link Lnk is different. The reference section fuel efficiency FE0sc is, for example, the fuel efficiency for each link Lnk obtained experimentally as the vehicle 6 travels on the link Lnk without executing the inertia traveling control. The fuel efficiency index value FEind is an index value that represents the effect of the inertial traveling control.As can be seen from the calculation method of the fuel efficiency index value FEind, the fuel efficiency index value FEind is higher as the effect of the inertial traveling control is higher, that is, The higher the fuel consumption, the higher the value. When the display content determination unit 202 calculates the fuel efficiency index value FEind of the selected link LNKs, the greater the fuel efficiency index value FEind, that is, the higher the effect of the inertial traveling control, the higher the control execution effect flag of the selected link LNKs. Set a large value to FLG_efct. For example, the maximum change range that the fuel consumption index value FEind can take is experimentally determined in advance, and the maximum change range of the fuel consumption index value FEind is divided into five, and the fuel consumption index value FEind is small over the entire maximum change range. The first fuel efficiency index value range, the second fuel efficiency index value range, the third fuel efficiency index value range, the fourth fuel efficiency index value range, and the fifth fuel efficiency index value range are sequentially controlled from the side. Is experimentally set in advance to set. If the fuel efficiency index value FEind is within the first fuel efficiency index value range, the display content determination unit 202 sets the control execution effect flag FLG_efct to 1. If the fuel efficiency index value FEind is within the second fuel efficiency index value range, the display content determination unit 202 sets the control execution effect flag FLG_efct to 2. If the fuel efficiency index value FEind is within the third fuel efficiency index value range, the display content determination unit 202 sets the control execution effect flag FLG_efct to 3. If the fuel efficiency index value FEind is within the fourth fuel efficiency index value range, the display content determination unit 202 sets the control execution effect flag FLG_efct to 4. If the fuel efficiency index value FEind is within the fifth fuel efficiency index value range, that is, if the fuel efficiency index value FEind is greater than the upper limit value of the fourth fuel efficiency index value range, the display content determination unit 202 The control execution effect flag FLG_efct is set to 5. The display content determination unit 202 thus sets the control execution effect flag FLG_efct according to the fuel efficiency index value FEind, and then switches the completion flag FLG_end of the selected link LNKs from 0 to 1.

  As described above, when the completion flag FLG_end is switched to 1 for one selected link LNKs, the completion flag FLG_end is set to 0 again as in the display content determination unit 78 of the first embodiment. From the target links LNKi, one target link LNKi is selected as the selected link LNKs. Then, the display content determination control of this embodiment is repeatedly executed until the completion flag FLG_end of all the target links LNKi becomes 1.

  The display unit 204 displays the vehicle position and a map including roads around the vehicle position on the display device 64 as in the known navigation system, which is the same as the display unit 76 of the first embodiment. . However, since the display content determination unit 202 sets the flags FLG_fcyexc and FLG_efct, the display unit 204 matches the information indicated by the flags FLG_fcyexc and FLG_efct determined by the display content determination unit 202 in a pattern representing the link Lnk or By changing the color, it is displayed on the display device 64 in association with the target link LNKi. This is different from the display unit 76 described above. FIG. 9 shows a display example in which the information indicated by each of the flags FLG_fcyexc and FLG_efct is displayed on the display device 64 by the display unit 204. FIG. 9 shows a display example in which roads are displayed in a plane. For example, in FIG. 9, as in FIG. 5, the host vehicle image 90 shows the host vehicle position and the traveling direction, the node ND is extracted and displayed, and the solid line 92 is a series of the links Lnk. It shows a certain road. The display device 64 displays a control execution road image 210 and a control effect image 212 indicating a predetermined section of the road. Specifically, the control execution road image 210 and the control effect image 212 are images displayed corresponding to the same link Lnk, specifically, the target link LNKi in which the control execution frequency flag FLG_fcyexc is set to 1 or more. The control execution road image 210 is a dotted image in which dotted figures are connected along the solid line 92. The display unit 204 displays the color of the control execution road image 210 darker as the value of the control execution frequency flag FLG_fcyexc of the link Lnk corresponding to the control execution road image 210 increases. In other words, the height of the inertial running control execution frequency FCYexc obtained based on the history information DThis in the shade of color of the control execution road image 210 is within the predetermined range RGi with the current position of the vehicle 6 as a reference. Are displayed on the display device 64 in association with the link Lnk (traveling road). The control effect image 212 is a band-like image wider than the control execution road image 210 that overlaps the control execution road image 210. The display unit 204 displays the control effect image 212 in a different pattern or color so that it can be easily distinguished from the control execution road image 210, and the color of the control effect image 212 corresponds to the control effect image 212. The larger the value of the control execution effect flag FLG_efct of the link Lnk to be displayed is, the darker it is displayed. That is, the degree of the effect (the magnitude of the fuel consumption index value FEind) obtained by executing the inertia running control obtained based on the history information DThis, based on the shade of the color of the control effect image 212, is determined as the link Lnk within the predetermined range RGi. The information is displayed on the display device 64 in association with (traveling road).

  FIG. 10 is a flowchart for explaining a main part of the control operation of the electronic control device 200, and a part thereof differs from FIG. 7 showing the flowchart of the first embodiment in steps SA7-1 and SA8-1. It is an excerpt figure of the flowchart extracted in order to show. The control operation illustrated in FIG. 10 is executed alone or in parallel with other control operations. As shown in FIG. 10, SA7 and SA8 in the flowchart of FIG. 7 are respectively replaced with SA7-1 and SA8-1 in the flowchart of FIG. 10, and SA1 to SA6 of the flowchart of FIG. The same applies to the flowchart of FIG. Therefore, the description of SA1 to SA6 common to the first embodiment is omitted. In this embodiment, SA4, SA5, and SA6 correspond to the display content determination unit 202.

  In SA7-1 following SA6, the flowchart of FIG. 11 is executed. FIG. 11 is a flowchart showing a subroutine executed in SA7-1. All the steps in FIG. 11 correspond to the display content determination unit 202.

  In SC1 in FIG. 11, the travel number NMrun and the control execution number NMexc of the inertial travel control corresponding to the link ID of the selected link LNKs selected in SA6 in FIG. 10 are read from the history information DThis. Then, the inertia traveling control execution frequency FCYexc in the selected link LNKs is calculated based on the read traveling number NMrun and control execution number NMexc. After SC1, the process proceeds to SC2.

  In SC2, the control execution frequency flag FLG_fcyexc of the selected link LNKs is set according to the execution frequency FCYexc calculated in SC1. The control execution frequency flag FLG_fcyexc is set to a larger value as the execution frequency FCYexc is higher. For example, if the control execution frequency NMexc is zero, that is, the execution frequency FCYexc is zero, the control execution frequency flag FLG_fcyexc is left at an initial value (= 0). After SC2, the process proceeds to SC3.

  In SC3, it is determined whether or not the control execution frequency flag FLG_fcyexc is zero. If the determination in SC3 is affirmative, that is, if the control execution frequency flag FLG_fcyexc is zero, the process proceeds to SC6. On the other hand, if the determination of SC3 is negative, the process proceeds to SC4.

  In SC4, the fuel consumption index indicating the effectiveness of the inertial running control on the selected link LNKs based on the reference fuel consumption FE0sc set in advance and the section fuel consumption FEsc included in the history information DThis. The value FEind is calculated. After SC4, the process proceeds to SC5.

  In SC5, the control execution effect flag FLG_efct of the selected link LNKs is set according to the fuel consumption index value FEind calculated in SC4. The control execution effect flag FLG_efct is set to a larger value within a range of 1 to 5 as the fuel consumption index value FEind is larger. After SC5, the process proceeds to SC6.

  In SC6, the completion flag FLG_end of the selected link LNKs is switched from 0 to 1 as in SB11 of FIG. When the setting switching of the completion flag FLG_end in SC6 is completed, the process proceeds to SA5, which is the next step after SA7-1 in FIG.

  Returning to FIG. 10, in SA8-1 corresponding to the display unit 204, as shown in FIG. 9, for example, according to the values of the control execution frequency flag FLG_fcyexc and the control execution effect flag FLG_efct, the control execution road image 210 and the control effect image An image such as a road around the vehicle position including 212 is displayed on the display device 64 together with the vehicle image 90.

  This embodiment has the following effects (B1) and (B2). (B1) According to the present embodiment, as shown in FIG. 4, the history information DThis includes information related to the inertia traveling control (predetermined traveling control), for example, the number of control executions NMexc of the inertia traveling control, and The section fuel consumption FEsc at the time of executing the inertia traveling control is included. Then, as shown in FIG. 9, the display unit 204 displays the height of the inertia traveling control execution frequency FCYexc obtained based on the history information DThis based on the shade of color of the control execution road image 210. Is displayed on the display device 64 in association with the link Lnk (traveling road) within the predetermined range RGi with the current position as a reference. Therefore, it is possible to confirm whether or not the inertia traveling control is executed or not executed by the driver's vehicle operation, and it is possible to enhance the feeling that the driver is involved in the execution of the inertia traveling control by the vehicle operation. is there.

  (B2) According to the present embodiment, as shown in FIG. 9, the display unit 204 executes the inertial running control obtained based on the history information DThis with the shade of the color of the control effect image 212. The degree of the effect (the magnitude of the fuel efficiency index value FEind) is displayed on the display device 64 in association with the link Lnk (traveling road) within the predetermined range RGi. Therefore, the driver can confirm the effect obtained by executing the inertia running control.

  The functional block diagram of the present embodiment is the same as FIG. As shown in FIG. 2, the electronic control device 260 that is the vehicle control device of the present embodiment is similar to the electronic control device 60 of the first embodiment in that the traveling control unit 70, the vehicle position specifying unit 72, and the learning unit 74 It has. However, unlike the electronic control unit 60, the electronic control unit 260 includes a display unit 264 instead of the display unit 76, and the learning unit 74 includes a display content determination unit 262 instead of the display content determination unit 78. .

  The display content determination unit 262 as the display content determination means is mainly different from the display content determination unit 78 of the first embodiment in the types of flags to be switched and set. The display content determination unit 262 determines one or more target links LNKi in the same manner as the display content determination unit 78. When the display content determination unit 262 determines the target link LNKi, the display content determination unit 262 sets various flags for each of the target links LNKi. Specifically, for each of the target links LNKi, the completion flag FLG_end, and a control forcible end flag FLG_sht indicating that the inertial traveling control has been forcibly terminated by failsafe or the like in the latest vehicle traveling, There is provided a control-time effect deficiency flag FLG_nef indicating that the effect of the inertial running control is equal to or lower than a predetermined level LVLef, for example, that the effect of executing the inertial running control is absent. The values of the flags FLG_end, FLG_sht, and FLG_nef at this time are all zero, which is an initial value. When the display content determination unit 262 provides the flags FLG_end, FLG_sht, and FLG_nef, the display content determination unit 262 performs display content determination control for determining the display content related to the inertia traveling control for each target link LNKi, and the display content determination control is completed The completion flag FLG_end of the target link LNKi is switched from 0 to 1.

  The display content determination control of the present embodiment will be described. The display content determination unit 262 first sets a completion flag FLG_end to 0 in order to determine the display content related to the inertia traveling control for all target links LNKi. One target link LNKi is selected from the existing target links LNKi. The selected target link LNKi is referred to as a selected link LNKs. This is the same as the first embodiment. When the display content determination unit 262 determines the selected link LNKs, the presence / absence of forced termination of the inertial traveling control stored corresponding to the link ID of the selected link LNKs in the history information DThis is determined to be forcibly terminated. Judge whether or not. If the result of the determination shows that the link ID of the selected link LNKs is forcibly terminated, the display content determination unit 262 switches the control forced termination flag FLG_sht of the selected link LNKs from 0 to 1.

  In addition, after setting the selected link LNKs, the display content determining unit 262 first corresponds to the link ID of the selected link LNKs from the history information DThis in order to perform switching setting of the control effect deficiency flag FLG_nef. The control execution number NMexc of the inertia traveling control is read out, and it is determined whether or not the read control execution number NMexc is one or more. This is because if the number of control executions NMexc is 0, it is not possible to determine whether or not there is an effect by executing the inertial running control.

  As a result of the determination regarding the control execution number NMexc, the display content determination unit 262 executes the inertial running control on the selected link LNKs when the control execution number NMexc on the selected link LNKs is 1 or more. It is determined whether the effect of is less than a predetermined level LVLef. For example, the degree of effect due to the execution of the inertial traveling control is represented by the fuel efficiency index value FEind, as in the second embodiment, and in this embodiment, the inertial traveling control is performed on the reference zone fuel efficiency FE0sc. This is the fuel efficiency for each link Lnk obtained experimentally as the vehicle 6 travels on the link Lnk. The predetermined level LVLef is a level of an effect that can be determined to be equal to no effect if the effect by the execution of the inertial running control is equal to or less than the predetermined level LVLef. A fuel consumption index determination value FE1ind is set as a determination value for comparison with the fuel efficiency index value FEind corresponding to a predetermined level LVLef. For example, the fuel consumption index determination value FE1ind is experimentally set to 1 or approximately 1. Therefore, as described above, the display content determination unit 262 determines whether or not the effect due to the execution of the inertia traveling control on the selected link LNKs is equal to or lower than the predetermined level LVLef. In this case, the fuel efficiency index value FEind of the selected link LNKs is calculated, and it is determined whether or not the calculated fuel efficiency index value FEind is equal to or less than the predetermined fuel efficiency index determination value FE1ind. When the fuel consumption index value FEind of the selected link LNKs is equal to or less than the fuel efficiency index determination value FE1ind as a result of the determination, the display content determination unit 262 sets the control effect shortage flag FLG_nef of the selected link LNKs from 0 to 1. Switch to.

  The display content determination unit 262 thus sets the control forced end flag FLG_sht according to whether or not the inertial running control is forcibly terminated, and the fuel consumption index when the control execution count NMexc is 1 or more. After setting the control effect deficiency flag FLG_nef according to the value FEind, the completion flag FLG_end of the selected link LNKs is switched from 0 to 1.

  As described above, when the completion flag FLG_end is switched to 1 for one selected link LNKs, the completion flag FLG_end is set to 0 again as in the display content determination unit 78 of the first embodiment. From the target links LNKi, one target link LNKi is selected as the selected link LNKs. Then, the display content determination control of this embodiment is repeatedly executed until the completion flag FLG_end of all the target links LNKi becomes 1.

  The display unit 264 displays the vehicle position and a map including roads around the vehicle position on the display device 64 as in the known navigation system, which is the same as the display unit 76 of the first embodiment. . However, since the display content determination unit 262 sets the flags FLG_sht and FLG_nef, the display unit 264 matches the information indicated by the flags FLG_sht and FLG_nef determined by the display content determination unit 262 in a pattern representing the link Lnk or By changing the color, it is displayed on the display device 64 in association with the target link LNKi. This is different from the display unit 76 described above. For example, a road image representing a link Lnk (traveling road) having the control forced end flag FLG_sht of 1, a road image representing a link Lnk (running road) having the control effect deficiency flag FLG_nef being 1, and their links The road image representing the link Lnk other than Lnk is predetermined with a mutually different pattern or color, and the display unit 264 displays the road image on the display device 64 according to the values of the flags FLG_sht and FLG_nef. . That is, the display unit 264 displays the road image representing the link Lnk having the control forced end flag FLG_sht of 1 to indicate that the inertial traveling control has been forcibly ended, so that the current position of the vehicle 6 is Is displayed on the display device 64 in association with the link Lnk (traveling road) within the predetermined range RGi. In addition, by displaying a road image representing the link Lnk (traveling road) having the control effect shortage flag FLG_nef of 1, the inertial traveling control is executed in the history information DThis, and the effect of the execution is a predetermined level LVLef. The following is displayed on the display device 64 in association with the link Lnk (traveling road) within the predetermined range RGi. For example, the display unit 264 displays a plurality of types of the road images on the display device 64 in the same manner as in FIG. 5 or FIG. Since there may be a link Lnk in which the control forced end flag FLG_sht is 1 and the in-control effect insufficient flag FLG_nef is 1, a road image representing the link Lnk in which the control forced end flag FLG_sht is 1, A road image representing a link Lnk having a control effect deficiency flag FLG_nef of 1 can be displayed as an image representing the same link Lnk so as to overlap each other.

  FIG. 12 is a flowchart for explaining the main part of the control operation of the electronic control unit 260, and a part thereof differs from FIG. 7 showing the flowchart of the first embodiment in steps SA7-2 and SA8-2. It is an excerpt figure of the flowchart extracted in order to show. The control operation illustrated in FIG. 12 is executed alone or in parallel with other control operations. As shown in FIG. 12, SA7 and SA8 in the flowchart of FIG. 7 are replaced with SA7-2 and SA8-2 in the flowchart of FIG. 12, respectively. SA1 to SA6 in the flowchart of FIG. The same applies to the flowchart of FIG. Therefore, the description of SA1 to SA6 common to the first embodiment is omitted. In this embodiment, SA4, SA5, and SA6 correspond to the display content determination unit 262.

  In SA7-2 following SA6, the flowchart of FIG. 13 is executed. FIG. 13 is a flowchart showing a subroutine executed in SA7-2. All the steps in FIG. 13 correspond to the display content determination unit 262.

  In SD1 of FIG. 13, it is determined whether or not the inertial running control forcibly terminated is stored in the history information DThis corresponding to the link ID of the selected link LNKs. The If the determination of SD1 is affirmative, that is, if the presence or absence of forced termination of the inertial running control is forced termination, the process proceeds to SD2. On the other hand, if the determination of SD1 is negative, the process proceeds to SD3.

  In SD2, the control forced end flag FLG_sht of the selected link LNKs is switched from 0 to 1. After SD2, the process proceeds to SD3.

  In SD3, the control execution number NMexc of the inertia traveling control corresponding to the link ID of the selected link LNKs is read from the history information DThis, and whether or not the read control execution number NMexc is one or more times. Is judged. If the determination in SD3 is affirmative, that is, if the number of control executions NMexc is one or more, the process proceeds to SD4. On the other hand, if the determination of SD3 is negative, the process proceeds to SD6.

  In SD4, the fuel consumption index value FEind of the selected link LNKs is calculated in the same manner as in SC4 of FIG. Then, it is determined whether or not the fuel consumption index value FEind is equal to or less than the fuel consumption index determination value FE1ind. In short, it is determined whether or not the effect by the execution of the inertial running control represented by the fuel efficiency index value FEind is equal to or less than the predetermined level LVLef. For example, if the fuel efficiency index value FEind is equal to or less than the fuel efficiency index determination value FE1ind, it can be determined that there is no effect due to the execution of the inertial running control. If the determination in SD4 is affirmative, that is, if the fuel efficiency index value FEind is equal to or less than the fuel efficiency index determination value FE1ind, the process proceeds to SD5. On the other hand, when the determination of SD4 is negative, the process proceeds to SD6.

  In SD5, the control effect deficiency flag FLG_nef of the selected link LNKs is switched from 0 to 1. After SD5, the process proceeds to SD6.

  In SD6, the completion flag FLG_end of the selected link LNKs is switched from 0 to 1 as in SB11 of FIG. When the setting switching of the completion flag FLG_end in SD6 is completed, the process proceeds to SA5, which is the next step after SA7-2 in FIG.

  Returning to FIG. 12, in SA8-2 corresponding to the display unit 264, images of roads and the like around the vehicle position are displayed together with the vehicle image 90 in accordance with the values of the control forced termination flag FLG_sht and the control effect insufficient flag FLG_nef.

  For example, in the above-described first to third embodiments, the vehicle 6 is a hybrid vehicle including the engine 14 and the second electric motor MG2 that functions as a traveling electric motor, but only the engine 14 does not have the second electric motor MG2. The vehicle may be an engine vehicle that travels at the same time, or may be an electric vehicle (electric vehicle) that does not have the engine 14 and travels only by the second electric motor MG2.

  In the first to third embodiments, the inertia traveling control is exemplified as the predetermined traveling control of the present invention. However, the predetermined traveling control may be traveling control other than the inertia traveling control. Absent. For example, regenerative brake control that regeneratively operates the second electric motor MG2 to brake the vehicle 6 may be used. Further, if the vehicle 6 is provided with an automatic transmission, it may be a traveling control in which the automatic transmission is shifted down and the engine 14 is fuel cut at the time of deceleration. If the predetermined traveling control is different as described above, the traveling data stored as the history information DThis corresponds to the predetermined traveling control. The effect of the predetermined traveling control is, for example, an improvement in fuel efficiency, but is not limited to the fuel efficiency, and may be other effects such as an improvement in drivability and suppression of deterioration in durability.

The height of the execution frequency FCYexc can be expressed by increase / decrease. In addition, the shade of the color of the control effect image 212 shown in FIG. 9 represents the degree of the effect due to the execution of the inertia running control, but the degree of the effect is represented by the increase / decrease of the width of the control effect image 212. There is no problem.

  In the first embodiment, the flags FLG_ok, FLG_spddwn, FLG_spdup, and FLG_acoff are provided for each of the target links LNKi, but any one of the flags FLG_ok, FLG_spddwn, FLG_spdup, and FLG_acoff is not provided. You can also think about that. For example, the deceleration control execution estimation flag FLG_spddwn and the acceleration control execution estimation flag FLG_spdup are not provided, and the second road image 96 and the third road image 98 of FIG. 5 may not be displayed on the display device 64. . Similarly, it can be considered that one of the flags FLG_fcyexc and FLG_efct is not provided in the second embodiment. Further, in the above-described third embodiment, it can be considered that one of the flags FLG_sht and FLG_nef is not provided.

The display is not limited to the image, and may be displayed by, for example, a lamp color or a blinking state.

  In addition, each of the above-described embodiments can be implemented in combination with each other, for example, by setting priorities. For example, two of the first to third embodiments may be combined with each other, or all the embodiments may be combined with each other. For example, if the first to third embodiments are combined with each other, the images displayed on the display device 64 according to the flags FLG_ok, FLG_spddwn, FLG_spdup, FLG_acoff, FLG_fcyexc, FLG_efct, FLG_sht, and FLG_nef can be distinguished from each other.
