  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, the driving evaluation support device of the present invention is described as applied to the vehicle 1.

  FIG. 1 is a block diagram showing a schematic configuration of the vehicle 1. As shown in FIG. 1, the vehicle 1 includes an ECU (Electronic control unit) 11, a navigation device 12, a storage unit 13, a rotation speed sensor 21, a shift position sensor 22, a brake pedal stroke sensor 23, a brake hydraulic pressure sensor 24, a clutch pedal. A sensor 25, an acceleration sensor 26, an engine ECU 27, an in-vehicle ECU 28, an accelerator opening sensor 29, and a USB port 30 are provided.

  Although not shown, the vehicle 1 includes an ECU 11, a navigation device 12, a storage unit 13, a rotation speed sensor 21, a shift position sensor 22, a brake pedal stroke sensor 23, a brake hydraulic pressure sensor 24, a clutch pedal sensor 25, and an acceleration sensor. 26, the engine ECU 27, the in-vehicle ECU 28, the accelerator opening sensor 29, and the USB port 30 are provided with various devices for realizing functions as a vehicle.

  The ECU 11 is a control unit for determining the driving skill of the driver. The ECU 11 receives information input from the rotational speed sensor 21, shift position sensor 22, brake pedal stroke sensor 23, brake hydraulic pressure sensor 24, clutch pedal sensor 25, acceleration sensor 26, engine ECU 27, in-vehicle ECU 28, and accelerator opening sensor 29. Based on the above, the driving skill of the driver is determined. Processing for determining the driving skill of the driver will be described later (see: FIGS. 3 and 4).

  The rotational speed sensor 21 is provided, for example, in the vicinity of the wheel shaft (not shown) of the vehicle 1, detects the rotational speed of the wheel shaft, and calculates the vehicle speed of the vehicle 1 from the detected rotational speed. The rotation speed sensor 21 outputs the vehicle speed calculated in this way to the ECU 11. The rotational speed sensor 21 may detect only the rotational speed, and a predetermined control unit (for example, the ECU 11) may calculate the vehicle speed of the vehicle 1 based on the detection result.

  The shift position sensor 22 detects a shift position instructed by the driver. The shift position sensor 22 is operated, for example, by a paddle or a shift lever operated by a driver, moved from a predetermined shift to another shift, and an acceleration or deceleration instruction (hereinafter also referred to as an acceleration / deceleration instruction) is given to the transmission of the vehicle 1. The position of the other shifted shift is detected. The shift position sensor 22 outputs the detected shift position, that is, a shift instruction, to the ECU 11.

  The brake pedal stroke sensor 23 detects the amount of depression of the brake pedal, in other words, the size of the foot brake. The brake pedal stroke sensor 23 outputs the detected size of the foot brake to the ECU 11.

  The brake hydraulic pressure sensor 24 detects the hydraulic pressure of a hydraulic brake system (not shown), in other words, the size of the foot brake. The brake hydraulic pressure sensor 24 outputs the detected size of the foot brake to the ECU 11.

  Therefore, in the present embodiment, the size of the foot brake can be detected by using a value detected by either the brake pedal stroke sensor 23 or the brake hydraulic pressure sensor 24.

The clutch pedal sensor 25 detects the depression amount of the clutch pedal. The clutch pedal sensor 25 outputs the detected depression amount of the clutch pedal to the ECU 11.
The acceleration sensor 26 detects the longitudinal direction, traveling direction, and lateral acceleration or deceleration perpendicular to the traveling direction of the vehicle 1. The acceleration sensor 26 outputs the detected vertical direction, traveling direction, and horizontal direction acceleration or deceleration to the ECU 11.
The engine ECU 27 is a control unit that controls the rotational speed of the engine. The engine ECU 27 outputs the engine speed to the ECU 11.
The in-vehicle ECU 28 is a control unit that performs overall control of each device of the vehicle 1. The in-vehicle ECU 28 acquires, for example, the paddle position, the travel time of the vehicle 1, and the position information of the vehicle 1, and outputs the acquired information to the ECU 11.
The accelerator opening sensor 29 is a sensor that detects the opening of the accelerator. The accelerator opening sensor outputs the detected accelerator opening to the ECU 11.

  The USB port 30 is a port for connecting the ECU 11 and an external device. In this embodiment, a portable information communication device (for example, a smartphone, not shown) is connected to the USB port 30. The ECU 11 outputs driving skill determination data to the information communication device via the USB port 30. In addition, when the vehicle 1 is provided with the communication apparatus which communicates with an external device (for example, server), you may make it transmit driving skill determination data to a predetermined | prescribed data transmission destination using the said communication apparatus.

  FIG. 2 is a diagram illustrating an example of a data structure of the driving skill determination data D. As illustrated in FIG.

  As shown in FIG. 2, the driving skill determination data D is data used for determining the driving skill of the driver. In this embodiment, the date and time information, the determination result of the driving skill, the position information, and the engine rotation before downshifting. Number, operation time at shift down, G (acceleration) change value from clutch engagement operation to accelerator pedal depression operation, operation time at shift up, required time from shift up to acceleration start, shift knob / paddle operation After the regenerative braking, information such as a G change when a braking operation is further performed with the brake pedal is configured in association with the driver's operation.

The navigation device 12 assists the driving operation of the vehicle 1 in response to an instruction from the driver. The navigation device 12 presents, for example, the route to the destination and the determination result of the driving skill to the driver.
The navigation device 12 includes a touch panel 121, an audio output unit 122, a GPS 123, and a map information acquisition unit 124.

  The touch panel 121 includes a display unit and an input unit. The display unit displays information such as the route to the destination and the determination result of the driving skill to the driver. The input unit receives an instruction input from the driver. For example, the input unit receives a setting as to whether or not to determine the driving skill from the driver, and when the determination is made, displays the determination result on the display unit.

  The audio output unit 122 outputs audio at a timing when information is displayed on the driver, or outputs that the input has been received when an instruction input is received from the driver. For example, when the determination result of the driving skill is displayed on the display unit of the touch panel 121, the voice output unit 122 notifies the driver that the determination result is displayed by outputting a predetermined voice.

The GPS 123 is a global positioning system and acquires position information of the vehicle 1.
The map information acquisition unit 124 acquires map information around the vehicle 1 traveling. The current position of the vehicle 1 is notified to the driver by displaying the position acquired by the GPS 123 on the map acquired based on the map information.

  The storage unit 13 is a non-volatile storage medium such as a small hard disk drive or flash memory. The storage unit 13 stores the driving skill determination data D described with reference to FIG.

  Next, the driving skill evaluation process will be described. FIG. 3 is a flowchart illustrating an example of the driving skill evaluation process executed by the ECU 11. In the present embodiment, a description will be given of a case where a driving skill evaluation process is executed when a setting for performing driving skill evaluation is performed via the touch panel 121 of the navigation device 12 before the driver drives the vehicle 1. To do.

  When it is set to execute the driving skill evaluation process, as shown in FIG. 3, the ECU 11 determines whether or not the vehicle 1 is traveling (ST101). For example, the ECU 11 determines whether the vehicle 1 is traveling based on the engine speed input from the engine ECU 27 and the vehicle speed input from the rotation speed sensor 21. When it determines with not driving | running | working (ST101: NO), a process returns. That is, when the vehicle 1 is traveling, the driving skill evaluation process is executed.

  If it is determined that the vehicle is traveling (ST101: YES), the ECU 11 determines whether or not the transmission is manual (ST102). For example, the ECU 11 receives information about the configuration of the vehicle 1 from the in-vehicle ECU 28, and determines whether the transmission is a manual based on the information. When it is determined that the transmission is not manual (ST102: NO), the ECU 11 executes processing for a case where the transmission is other than manual. This process will be described later with reference to FIG.

  When it is determined that the transmission is manual (ST102: YES), the ECU 11 determines whether or not the vehicle 1 is decelerating (ST103). For example, the ECU 11 determines whether or not the vehicle 1 is decelerating based on information received from the brake pedal stroke sensor 23, the brake hydraulic pressure sensor 24, and the acceleration sensor 26.

  If it is determined that the vehicle is decelerating (ST103: YES), the ECU 11 determines whether or not the engine speed before the downshift is within a predetermined range (ST104). More specifically, the ECU 11 determines whether or not the engine speed input from the engine ECU 27 is within a predetermined range set in advance. The predetermined range can be arbitrarily set. As a result, it is possible to determine whether or not the driver is quickly and accurately adjusted to the engine speed.

  When it is determined that the engine speed before the downshift is within the predetermined range (ST104: YES), the ECU 11 determines whether or not the operation time during the downshift is within the predetermined time (ST105). More specifically, it is determined whether or not the time for the driver to decelerate the vehicle 1 by operating a clutch or a shift lever is within a predetermined time. This makes it possible to determine whether or not the driver is performing a useless operation when shifting down.

  When it is determined that the operation time until the downshift is equal to or shorter than the predetermined time (ST105: YES), the ECU 11 determines that the acceleration change (hereinafter referred to as G change) from the clutch engagement operation to the accelerator pedal depression operation is equal to or less than the predetermined value. It is determined whether or not there is (ST106). More specifically, it is determined whether the acceleration in the vertical direction, the traveling direction, and the horizontal direction input from the acceleration sensor 26 is less than or equal to a predetermined value. Thereby, it can be determined whether the driver is accelerating the vehicle smoothly.

  When it is determined that the G change from the clutch engagement operation to the accelerator pedal depression operation is less than or equal to a predetermined value (ST106: YES), the ECU 11 determines that the driving skill is “◯” (good) (ST107). This determination result is displayed on the touch panel 121 of the navigation device 12. FIG. 5 shows a determination result display example 121a displayed on the touch panel 121 when it is determined that the driving skill is good. As shown in FIG. 5, the date / time, location, determination result ○ “Good”, advice (very good), and parameter values used for determination of driving skill are displayed. Note that the advice is not limited to the advice, and may be advice related to determination of the driving skill. Another advice is, for example, “Accurate, no useless operation, driving smoothly”.

  Further, when it is determined that the engine speed before the downshift is not within the predetermined range (ST104: NO), when it is determined that the operation time until the downshift is not less than the predetermined time (ST105: NO), or the clutch engagement operation When it is determined that the G change from the accelerator pedal operation to the accelerator pedal depression operation is not less than the predetermined value (ST106: NO), the ECU 11 determines that the driving skill score is “Δ” (normal) (ST108).

  This determination result is displayed on the touch panel 121 of the navigation device 12. FIG. 6 shows a determination result display example 121b displayed on the touch panel 121 when the driving skill is determined to be normal. As shown in FIG. 6, the date / time, location, determination result Δ “normal”, advice (may be better), and parameter values used for determination of driving skill are displayed. Note that the advice is not limited to the advice, and may be advice related to determination of the driving skill. Another advice is, for example, “Accurate and no useless operation, but smooth operation is not possible” (when ST104 and ST105 are YES and ST106 is NO).

  When it is determined in step ST103 that the vehicle 1 is not decelerating (ST103: NO), the ECU 11 determines whether or not the vehicle 1 is accelerating (ST109). If it is determined that the vehicle 1 is not accelerating (ST109: NO), the process returns.

  When it is determined that the vehicle 1 is accelerating (ST109: YES), the ECU 11 determines whether or not the operation time during the upshifting is within a predetermined time (ST110). More specifically, it is determined whether or not the time for the driver to perform an acceleration operation on the vehicle 1 by operating a clutch or a shift lever is within a predetermined time. This makes it possible to determine whether or not the driver is performing a useless operation when shifting up.

  When it is determined that the operation time at the time of the shift up is within a predetermined time (ST110: YES), the ECU 11 determines whether the time from the shift up to the acceleration is equal to or shorter than the predetermined time (ST111).

  When it is determined that the time from the upshifting to the acceleration is within a predetermined time (ST111: YES), the ECU 11 determines that the driving skill score is “◯” (good) (ST107). The determination result is displayed on the touch panel 121 of the navigation device 12 as in the case described with reference to FIG.

  When it is determined that the operation time at the time of upshifting is not within the predetermined time (ST110: NO), or when it is determined that the time from the upshifting to the acceleration is not within the predetermined time (ST111: NO), the ECU 11 The driving skill score is determined to be “Δ” (normal) (ST108). This determination result is displayed on the touch panel 121 of the navigation device 12 as in the case described with reference to FIG.

  When the ECU 11 determines the driving skill score (ST107, ST108, ST112), the ECU 11 determines whether to transmit the driving skill determination data D described with reference to FIG. 2 (ST113). The ECU 11 determines whether or not to transmit the driving skill determination data D based on, for example, a setting made in advance by the driver.

  When it is determined that the driving skill determination data D is to be transmitted (ST113: YES), the ECU 11 transmits the driving skill determination data D to the information communication device connected to the USB port 30, and then the process is returned to determine the driving skill determination. When it is determined not to transmit the data D (ST113: NO), the ECU 11 returns the process without transmitting the driving skill determination data D to the information communication device.

  Next, processing other than the manual (ST102: NO) will be described with reference to FIG. As shown in FIG. 4, the ECU 11 determines whether the vehicle 1 is an electric vehicle (ST201). ECU11 receives the information regarding the structure of the vehicle 1 from vehicle-mounted ECU28, for example, and determines whether the vehicle 1 is an electric vehicle based on the said information.

  When it is determined that the vehicle 1 is an electric vehicle (ST201: YES), the ECU 11 determines whether the shift position is the B (brake) position or whether there is a paddle (ST202). When it is determined that the shift position is not the B position or there is no paddle (ST202: NO), the process proceeds to ST113, and it is not necessary to transmit the driving skill determination data D, and thus the process returns.

  When it is determined whether the shift position is the B position or there is a paddle (ST202: YES), the ECU 11 determines whether the vehicle 1 is decelerating (ST203). For example, the ECU 11 determines whether the deceleration of the vehicle 1 is equal to or less than a predetermined value based on information input from the brake pedal stroke sensor 23, the brake hydraulic pressure sensor 24, and the acceleration sensor 26.

  When it is determined that the vehicle 1 is decelerating (ST203: YES), the ECU 11 determines whether the G change when the braking operation is further performed with the brake pedal after the regenerative braking by the shift knob / paddle operation is less than a predetermined value. (ST204). This determination is used for determining the driving skill because when the shift down is delayed or when the operation amount is insufficient, the deceleration during the foot brake operation becomes more than normal.

  When it is determined that the G change when the braking operation is further performed by the brake pedal after the regenerative braking by the shift knob / paddle operation (ST204: YES), the ECU 11 sets the driving skill score to “◯” (good) (ST205). This determination result is displayed on the touch panel 121 as in the case described with reference to FIG.

  When it is determined that the vehicle 1 is not decelerating (ST203: NO), or after the regenerative braking by the shift knob / paddle operation and when it is determined that the G change when the braking operation is further performed by the brake pedal is not less than the predetermined value (ST204) : NO), the ECU 11 determines that the driving skill score is “Δ” (normal) (ST206). This determination result is displayed on the touch panel 121 as in the case described with reference to FIG.

  When it is determined in step ST201 that the vehicle 1 is not an electric vehicle (ST201: NO), the ECU 11 determines whether the shift position is the S (sports) position or whether there is a paddle (ST207). If it is determined that the shift position is not the S position or that there is no paddle (ST207: NO), the process proceeds to ST113, and it is not necessary to transmit the driving skill determination data D, and the process returns.

  When it is determined that the shift position is the S position or there is a paddle (ST207: YES), the ECU 11 determines whether or not the vehicle 1 is decelerating (ST208).

  When it is determined that the vehicle 1 is decelerating (ST208: YES), the ECU 11 determines whether or not the G change when the braking operation is further performed with the brake pedal after the regenerative braking by the shift knob / paddle operation is less than a predetermined value. Determine (ST209). In this determination, when the downshift is delayed or when the operation amount is insufficient, the deceleration during the foot brake operation is more than normal, so that the determination of the driving skill is the same as in step ST204. It is.

  When it is determined that the change in G when the brake pedal is further operated after the regenerative braking by the shift knob / paddle operation is below a predetermined value (ST209: YES), the ECU 11 sets the driving skill score to “◯” (good) (ST205). This determination result is displayed on the touch panel 121 as in the case described with reference to FIG.

  When it is determined that the vehicle is not decelerating (ST208: NO), the ECU 11 determines whether the vehicle 1 is accelerating (ST210). When it is determined that the vehicle 1 is accelerating (ST210: YES), the ECU 11 determines whether or not the operation time at the time of shifting up is within a predetermined time (ST211). This makes it possible to determine whether or not the driver is performing a useless operation when shifting up.

  When it is determined that the operation time at the time of the shift up is within a predetermined time (ST211: YES), the ECU 11 determines whether or not the time from the shift up to the acceleration is within a predetermined time (ST212). Thereby, it can be determined whether the driver is accelerating the vehicle smoothly.

  When it is determined that the time from the upshift to the acceleration is within a predetermined time (ST212: YES), the ECU 11 determines that the driving skill score is “◯” (good) (ST205). This determination result is displayed on the touch panel 121 as in the case described with reference to FIG.

  Further, when it is determined that the vehicle 1 is not accelerating (ST210: NO), when the time from the upshifting to the acceleration is not within a predetermined time (ST211: NO), or when the operation time at the upshifting is not less than the predetermined time (ST212: NO), or after the regenerative braking by the shift knob / paddle operation described above, if the G change when the braking operation is further performed by the brake pedal is not less than the predetermined value (ST209: NO), the ECU 11 The score is determined to be “Δ” (normal) (ST206). This determination result is displayed on the touch panel 121 as in the case described with reference to FIG.

  After the ECU 11 determines the driving skill of the driver (ST205, ST206, ST213), the process proceeds to the above-described step ST113 (see: FIG. 3). Therefore, if the setting is to transmit the driving skill determination data D (ST113: YES), the ECU 11 transmits the driving skill determination data D to a predetermined transmission destination (for example, a terminal device) and transmits the driving skill determination data D. If not set (ST113: NO), the process returns without transmitting the driving skill determination data.

  Next, when the vehicle 1 is a transmission specification, the determination point at the time of downshifting is demonstrated using a timing chart. FIG. 7 is a diagram illustrating an example of a timing chart at the time of downshifting (for example, from the 3rd gear to the 2nd gear).

  In FIG. 7, the timing t1 indicates that the accelerator is OFF, the timing t2 indicates that the brake is ON, the timing t3 indicates that the clutch is disengaged, the timing t4 indicates a shift operation by increasing the engine speed, the timing t5 indicates clutch engagement, and the timing t6 indicates acceleration. Yes.

  The accelerator opening is determined on the basis of information on the accelerator opening from the accelerator opening sensor 29, the engine speed is determined on the basis of information from the engine ECU 27, and brake ON / OFF is determined by brake pedal stroke. Judgment is made based on information from the sensor 23 (or the brake hydraulic pressure sensor 24), clutch release / engagement is judged based on information from the clutch pedal sensor 25, and shift position is judged based on information from the shift position sensor 22. The G change is determined by the ECU 11 based on the information from the acceleration sensor 26.

  When the accelerator opening becomes 0 percent at timing t1, the engine (ENG) rotational speed gradually decreases. Thereafter, at timing t2, the brake is turned on and the brake pedal stroke is increased. At timing t3, the clutch is released from the engaged state and the accelerator opening and the engine speed are increased.

  Thereafter, at timing t4, when the engine speed is increased, the shift position changes from the third gear to the second gear. Then, at the timing t5 immediately after, the brake pedal stroke becomes 0%, and the clutch is changed from the released state to the connected state. Then, from the timing t6, the accelerator opening and the engine speed increase.

  Further, the G change is on the deceleration side from timing t1 to t3, and is on the acceleration side from timing t6.

  Time W1 is the time from timing t2 to t6, and is the time from the brake ON to the accelerator pedal depression operation. If the time W1 is within a predetermined time, the driving skill is determined as “good”.

  The G change range W2 is a G change from timing t5 to t6, and is a G change from clutch engagement to accelerator pedal depression operation. If the G change within the G change range W2 is equal to or smaller than a predetermined value, that is, if the G change is small, the driving skill is determined to be “good”.

  The rotational speed range W3 is a rotational speed range for determining whether or not the engine rotational speed immediately before clutch engagement is within a predetermined range. If it is within this rotational speed range, the engine speed is adjusted according to the vehicle speed and the gear that has been changed, so that the driving skill is judged as “good”.

  According to the vehicle 1 configured as described above, the ECU 11 detects whether or not a shift (acceleration or deceleration) is being performed, and based on the operation information from the detection of the shift to the completion of the shift, the driver's driving skill And the determination result can be notified to the touch panel 121.

  Accordingly, the determination result of the driving skill is notified to the driver, and the driver can know the driving skill from when the driver performs the acceleration / deceleration operation to the vehicle 1 until the shift is completed, so the driver improves the driving skill. Can be made. By improving the driving skill of the driver, the safety of driving the vehicle can be improved. Moreover, the vehicle 1 can alert | report the advice regarding the driving operation according to the determination result with a determination result. For this reason, the driver can specifically know how the driving skill can be improved. The operation information is an operation time for at least one of a brake pedal, an accelerator pedal, a shift knob, and a paddle from when the gear shift is performed until the gear shift is completed, and the ECU 11 determines the driving skill of the driver based on the operation time. judge. For this reason, the driver can know the driving skill with respect to the operation time for at least one of the brake pedal, the accelerator pedal, the shift knob, and the paddle when shifting the vehicle.

  Further, the ECU 11 executes a process for determining the driving skill based on a predetermined instruction input to the input unit of the touch panel 121, and displays the determination result on the display unit of the touch panel 121. For this reason, the driver can check the driving skill determination result only when a predetermined instruction is given, so whether or not the driver determines the driving skill according to his / her driving skill and situation. It is possible to improve the usability of driving skill evaluation.

  The vehicle 1 also includes a USB port 30 that outputs driving skill determination data D to an external device. For this reason, for example, data can be stored in the communication terminal device possessed by the driver, or data related to determination of the driving skill of many drivers can be managed by the server.

  In the present embodiment, a case has been described in which processing for determining whether or not the transmission is manual in step ST102 is performed, but the present invention is not limited to this. For example, before the ECU 11 is mounted on the vehicle, if it is clear whether the transmission of the mounted vehicle is a manual or not, either the process when the ECU is a manual or the process other than the manual is executed. You may make it mount a process in ECU11. Further, when the driving skill determination process is first performed, whether the transmission of the vehicle is manual or non-manual is stored in a predetermined storage area, and the determination of step ST102 may not be performed from the next time.

  Further, in the present embodiment, when the setting of the driving skill evaluation is performed, when there is a timing for performing the driving skill evaluation during traveling, the determination result is displayed on the touch panel each time. This is not a limitation. For example, when the vehicle key is removed by the driver and traveling of the vehicle 1 is completed, or at the timing instructed by the driver, the ECU 11 reads out the determination result during traveling or within a predetermined period from the storage unit 13, and the touch panel 121. The driving skill determination result for the entire travel may be displayed.

  FIG. 8 is a diagram illustrating a display example 121c of the driving skill determination result in the entire travel. As shown in FIG. 8, advice (very good) is displayed along with the time of travel start and travel end, travel start location to travel end location, driving skill determination result “good”. The driving skill determination in the entire traveling may be determined as good or normal based on whether or not 70% of the results of the driving skill determination determined during traveling is “good”.

  Further, the vehicle 1 stores the driving skill determination data D in the storage unit 13 as history information, compares the determination result with the past determination result included in the history information, and notifies the driver of the comparison result. Also good.

  If comprised in this way, since the driver can compare the past driving skill with the current driving skill, he can know the progress of the driving skill.

  Further, for example, before driving, the vehicle 1 uses a touch panel 121 to specify a driver by a user ID or the like, associates the user ID and history information, and stores them in the storage unit 13. The past driving skill and the current driving skill may be compared using the history information corresponding to the user ID.

  If comprised in this way, when sharing a vehicle with a family, a condominium, etc., it will become possible to specify the driver who drives, and also when sharing the vehicle 1, a driving skill can be evaluated according to a driver. it can.

  The present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, you may delete some components from all the components shown by embodiment mentioned above. Furthermore, you may combine the structure of different embodiment.
