Description

The present invention relates to a vehicle control system that controls a vehicle that performs automatic driving.

In recent years, there has been much research into autonomous driving technology to reduce the burden on drivers and make driving more comfortable and safe, and some of them have already been put into practical use.

Patent Document 1 discloses a driving support system that includes a driving mode switch that allows the driver to arbitrarily select a manual driving mode in which the driver steers the vehicle, a first driving support mode, and a second driving support mode. Disclosed. Note that the first driving support mode and the second driving support mode have in common that they automatically drive the vehicle along the target route, but the first driving support mode requires the driver to keep the steering wheel. The second driving support mode is a driving mode that does not require the driver to keep the steering wheel.

In this driving support system, when the driver turns the driving mode switch OFF, the mode becomes manual driving mode, and when the driver turns the driving mode switch ON, either the first driving support mode or the second driving support mode is selected. The configuration is such that it can be selected and operated automatically.

JP2019-175208

The first driving support mode of the driving support system disclosed in Patent Document 1 includes active safety functions for preventing traffic accidents, such as lane keeping control and automatic emergency braking. Generally speaking, the less skilled a driver is at driving, the more likely the vehicle will be in a dangerous situation such as deviating from its lane or accidentally pressing the accelerator and brake, so the need for active safety functions increases.

However, in the configuration of Patent Document 1, the driver can select the manual driving mode using the driving mode switch and turn off the first driving support mode regardless of the driving technique. Therefore, it is possible to turn off preventive safety functions that are originally highly necessary for drivers with inexperienced driving skills, so if the vehicle is in a dangerous situation, it is possible to turn off preventive safety functions that are especially necessary for drivers with inexperienced driving skills. There was a problem that the preventive safety function sometimes did not function.

In order to solve the above-mentioned problems, the present disclosure aims to provide a vehicle control system that can prevent drivers with unskilled driving skills from limiting active safety functions and improve vehicle safety. purpose.

In order to solve the above-mentioned problems, the vehicle control system of the present disclosure is a vehicle control system that controls a vehicle equipped with an active safety function, and includes a personal authentication section that performs personal authentication of a driver, and a personal authentication section that performs personal authentication of a driver. a personal information management section that manages personal information about the driver who has received the information; a driver input acquisition section that allows the driver to input ON/OFF settings for preventive safety functions; A driving skill unskilled determination unit that determines whether the driving skills are unskilled; and an active safety function control unit that performs control calculations for active safety functions based on input information from the driver input acquisition unit and input results from the driving skill unskilled determination unit. The preventive safety function control unit does not reflect the OFF setting from the driver input acquisition unit when the driving skill inexperience determination unit determines that the driver's driving skills are immature, and the personal information management unit does not reflect the OFF setting from the driver input acquisition unit. At least one of driver's license information, driving history information, and automobile insurance information is managed, and the driving skill inexperience determining unit uses the information to determine whether the driver's driving skill is inexperienced. .

According to the vehicle control system according to the present disclosure, when the driving skill inexperience determining unit determines that the driver's driving skill is inexperienced, the OFF setting from the driver input acquisition unit is not reflected, thereby preventing the driver with inexperienced driving skill from reflecting the OFF setting from the driver input acquisition unit. Even if the safety function is set to OFF, the state in which the active safety function functions can be maintained without reflecting the setting, so that the safety of the vehicle can be improved.

The car insurance information here can be any personal information related to the driver's driving skills, such as the insurance grade, number of times the insurance has been used, accident history, accident type (assault, damage, own loss), etc. .

Next, the driver input acquisition section 4 will be explained. The driver input acquisition unit 4 receives setting input such as ON/OFF of the preventive safety function from the driver via, for example, a touch panel provided on the display. Active safety functions that can be set by the driver include emergency automatic braking, lane departure prevention function, auto cruise ON/OFF, following distance setting, vehicle speed setting, pedal misapplication prevention function, rear side vehicle approach warning, warning sound volume, etc. can give.

Here, the driver input acquisition unit 4 may be configured to input settings using switches provided around the display or around the steering wheel, instead of inputting settings using a touch panel provided on the display. Alternatively, a method of inputting settings by recognizing the driver's voice or gesture, or a method of inputting settings from a terminal such as a smartphone may also be used.

Next, the driving skill inexperience determining section 5 will be explained. When the driving skill inexperience determining unit 5 receives the setting input regarding the preventive safety function from the driver input acquisition unit 4, the driving skill determining unit 5 determines whether the driver is a driver who has been authenticated by the personal authentication unit 2 based on the personal information from the personal information management unit 3. It is determined whether or not the driver's driving skills are unskilled, and the input result is transmitted to the preventive safety function control unit 7 along with the setting input from the driver input acquisition unit 4. In addition, in this specification, a state in which a person can sufficiently respond to a crisis based on his or her own judgment even without preventive safety functions is defined as mature, and a state that has not reached this level is defined as unskilled.

Next, the vehicle information acquisition section 6 will be explained. The vehicle information acquisition unit 6 acquires information that can be used to control preventive safety functions, which is obtained by sensors and cameras installed in the vehicle. Examples include vehicle speed, yaw rate, surrounding obstacles recognized by the camera, white line information, etc.

Next, the preventive safety function control section 7 will be explained. The preventive safety function control unit 7 calculates braking instructions and steering instructions for the preventive safety function to the actuator 9 based on the input results from the driving skill inexperience determination unit 5 and the vehicle information from the vehicle information acquisition unit 6. do. The preventive safety functions handled by the preventive safety function control unit 7 include emergency automatic braking, lane departure prevention function, auto cruise, pedal misapplication prevention function, rear side vehicle approach warning, and the like.

Next, the driver notification section 8 will be explained. The driver notification unit 8 notifies the driver of information that needs to be notified to the driver, such as information based on the input results of the driving skill insufficiency determination unit 5 and an emergency automatic braking function warning.

Here, the driver notification unit 8 is configured, for example, by a display specially installed in the vehicle, but it may also be configured to be displayed on a navigation screen, a meter, a HUD (Head-Up Display), a terminal such as a smartphone, etc. . Further, any configuration may be used as long as it can notify the driver of information such as sound or light that needs to be notified.

Next, the actuator 9 will be explained. The actuator 9 is a device that performs acceleration, braking, steering, etc. of the vehicle based on control instructions from the preventive safety function control unit 7, and includes, for example, an engine, brakes, electric power steering, and an ECU (Electronic Control Unit) that controls them. ) etc. Further, the actuator 9 may issue instructions to a lighting system such as a headlight or a hazard lamp.

From here on, the operation of the vehicle control system according to the first embodiment will be explained. FIG. 2 is a flowchart showing the operation of the vehicle control system according to Embodiment 1 of the present invention.

The vehicle control system 1 first acquires personal information using the personal authentication section 2 and authenticates the driver (step S101).

Next, the personal information management section 3 manages the personal information corresponding to the driver authenticated by the personal authentication section 2, and transmits it to the driving skill inexperience judgment section 5 (step S102).

Next, the driver input acquisition unit 4 acquires setting input information such as ON/OFF for the preventive safety function from the driver (step S103).

Next, the driving skill inexperience determining unit 5 determines whether the driver's driving skills are inexperienced based on the driver's personal information obtained from the personal information management unit 3, and transmits the determination information to the preventive safety function control unit 7 ( Step S104).

Next, the vehicle information acquisition section 6 acquires information regarding the vehicle and the surroundings of the vehicle, and transmits it to the preventive safety function control section 7 (step S105).

Next, the preventive safety function control unit 7 receives the input results and the input information regarding the preventive safety function from the driving skill inexperience determination unit 5, and the information regarding the vehicle from the vehicle information acquisition unit 6, and determines whether the active safety function is necessary. If so, control calculations for the active safety function are performed from the received information regarding the vehicle (step S106).

Next, the driver notification unit 8 notifies the driver of the input results from the driving skill inexperience determining unit 7, the warning from the emergency automatic braking function, etc. (step S107).

Finally, the actuator 9 performs control related to acceleration, braking, and steering of the vehicle, such as brakes and electric power steering, based on control instructions from the preventive safety function control unit 7 (step S108).

From here on, the operation of step 104 of the driving skill inexperience determining section 5 will be explained in detail using the emergency automatic braking function among the preventive safety functions using FIG. FIG. 3 is a flowchart illustrating the operation of the driving skill inexperience determining unit 5 according to the first embodiment of the present disclosure. Note that when the driver has not set the preventive safety function using the driver input acquisition unit 4, the preventive safety function is set to ON. Further, although the automatic emergency braking function is described here as an example, it is assumed that the same configuration applies to other preventive safety functions.

First, the emergency automatic brake function OFF is inputted by the driver in the driver input acquisition section 4 . (Step S1041).

The driving skill inexperience determining unit 5, which has received the setting to turn off the emergency automatic braking function from the driver input acquisition unit 4, acquires personal information regarding the driver authenticated by the personal authentication unit 2 from the personal information management unit 3 (step S1042). ).

Next, the driving skill inexperience determining unit 5 uses the driver's driver's license information among the managed personal information to determine whether the driver is a new driver based on classification information such as new driver, ordinary driver, and excellent driver. If so, it is determined that the driver's driving skills are inexperienced (step S1043). If it is determined that the driver's driving skills are immature, even if the driver tries to turn off the emergency automatic braking function using the driver input acquisition section 4, the settings from the driver input acquisition section 4 are not reflected in the active safety function control section 5. (step S1044).

If it is determined in step S3 that the driver is not a new driver, then if the driver's driver's license information shows that the driver has caused accidents or caused injuries to himself or herself more than a certain number of times, it is determined that the driver's driving skills are inexperienced. A judgment is made (step S1045). If it is determined that the driving technique is insufficient, even if the driver attempts to turn off the emergency automatic braking function using the driver input acquisition unit 4, the OFF setting from the driver input acquisition unit 4 will be reflected in the active safety function control unit 7. (Step S1044).

In addition, if it is determined that the number of accidents resulting in at-fault or self-inflicted injury is less than a certain number of times, then based on the driver's driver's license information, if the points on the driver's license are above a certain number, it is determined that the driver's driving skills are immature. (Step S1046). If it is determined that the driving technique is insufficient, even if the driver attempts to turn off the emergency automatic braking function using the driver input acquisition unit 4, the OFF setting from the driver input acquisition unit 4 will be reflected in the active safety function control unit 7. Try not to. (Step S1044).

If it is determined that the number of points on the driver's license is less than a certain point, the setting to turn off the emergency braking function from the driver input acquisition unit 4 is reflected in the active safety function control unit 7, and the emergency automatic braking function is restricted. (Step S1047).

In addition, in FIG. 3, whether or not the driver's driving skills are unskilled is determined based on the driver's driving license information, but it may be determined based on the driver's driving history information. For example, if the driver has been driving for less than a certain number of years, it is determined that the driver's driving skills are immature, and even if the driver attempts to turn off the emergency automatic braking function using the driver input acquisition unit 4, the driver input acquisition unit 4 The OFF setting may not be reflected in the preventive safety function control unit 7.

In addition, if the driver's driving history information indicates that the number of driving times is less than a certain number, it is determined that the driver's driving skills are insufficient, and even if the driver attempts to turn off the emergency automatic braking function in the driver input acquisition section 4, the driver input The OFF setting from the acquisition unit 4 may not be reflected in the preventive safety function control unit 7.

The driver's driving history information is not limited to the number of times they have driven, but also includes driving frequency below a certain threshold, driving distance below a certain distance, traffic violations above a certain number of times, acceleration/deceleration during driving above a certain frequency, acceleration/deceleration, etc. One or more elements of the driving history information, such as the absolute value of deceleration being greater than a certain threshold, the number of times the emergency automatic braking function has been activated more than a certain number of times, and the number of times the lane departure prevention function has been activated more than a certain number of times. It may also be used to determine whether driving skills are inexperienced.

Furthermore, it may be determined whether the driver's driving skills are immature based on the information on the automobile insurance that the driver subscribes to, instead of the driver's driver's license information. For example, if the insurance grade is below a certain grade, it is determined that the driver's driving skills are inexperienced, and the driver tries to set the emergency automatic braking function to OFF using the driver input acquisition section 4. may not be reflected in the preventive safety function control unit 7. In addition, one or more elements of car insurance information, such as the number of insurance usages exceeding a certain number, the number of accidents exceeding a certain number, and the number of accidents resulting in at-fault or self-inflicted injury, etc., can be used to determine whether driving skills are immature. Even if the driver attempts to set the emergency automatic brake function to OFF using the driver input acquisition unit 4 after determining that .

In the flowchart of FIG. 3, three elements in the driver's license information are used to determine whether the driver's driving skills are inexperienced, but the number does not matter as long as at least one element is used.

In addition, the driving skill inexperience determining unit 5 used to determine whether a driver's driving skill is inexperienced based on one of the driver's license information, driving history information, and automobile insurance information, but it uses a combination of multiple items to determine whether or not the driver's driving skill is inexperienced. It may also be determined whether the driver's driving skills are unskilled. By combining multiple items, it is possible to determine that a driver's driving skills are inexperienced, even if he or she is an excellent driver on his or her driver's license, if he or she has had more than a certain number of accidents or violations in the past. It is possible to more accurately understand whether the vehicle is underdeveloped or not, thereby improving vehicle safety.

From here on, a modification of the first embodiment will be explained. FIG. 4 is a driving skill point map of the preventive safety function control determination unit 5 according to a modification of the first embodiment of the present disclosure.

The driving skill point map is used by the driving skill inexperience determining unit 5 to make a determination using a plurality of pieces of personal information. Each piece of personal information is evaluated with a score, and based on the total score of each piece of personal information, the driving skill inexperience determining section 5 determines whether or not the driver's driving skill is inexperienced.

For example, as shown in FIG. 4, evaluation points are set in three stages from 1 point to 3 points for each of three pieces of personal information: driver's license classification, number of accidents, and insurance grade. Here, if the driving skill is judged to be immature when the total score H of the driving skill points is 5 points or less, if the driver has a new license classification, one accident, and the insurance class is 6, the driving skill point will be Let H be the sum of
H=1+2+1=4
Since H is 5 points or less, the driver is judged to have poor driving skills.

In FIG. 4, the evaluation items are determined using three points: driver's license classification, number of accidents, and insurance grade, but other driver's license information, driving history information, and car insurance information may be combined. In addition, in Figure 4, evaluation points were set in three stages for driving skill points, and if the total score was 5 points or less, the driving skill was judged to be unskilled, but the score setting is set so that driving skill can be accurately judged. It doesn't matter what it is.

As explained above, the vehicle control system 1 according to the present embodiment includes the driving skill inexperience determining unit 5, and when receiving input of settings related to active safety functions from the driver input acquisition unit 4 through driver operation, the vehicle control system 1 according to the present embodiment The skill inexperience determining unit 5 determines whether the driver's driving skills are inexperienced based on the personal information about the driver from the personal information management unit 3, and when it is determined that the driver's driving skills are inexperienced, the driver input acquisition unit The OFF setting from 4 is not reflected in the preventive safety function control unit 7.

As a result, the active safety function will not turn off and will remain ON while a driver with unskilled driving skills is driving, and will activate the active safety function when the vehicle is in a dangerous situation. safety can be ensured.

In addition, the personal information management section 3 manages at least one of driver's license information, driving history information, and automobile insurance information as personal information, and the driving skill inexperience judgment section 5 manages the information (personal information management section 3). It is possible to judge whether or not the driver's driving skills are immature using at least one of the driver's license information, driving history information, and automobile insurance information managed by the driver.

As a result, it is possible to determine whether the driver's driving skills are immature using personal information about the driver that is closely related to the preventive safety function, thereby improving the safety of the vehicle.

Further, the personal information management unit 3 manages at least two types of personal information among driver's license information, driving history information, and automobile insurance information, and the driving skill inexperience determining unit 5 manages driver's license information, driving history information, and automobile insurance information. It is possible to determine whether a driver's driving skills are immature by combining at least two pieces of information from the automobile insurance information.

This allows us to use multiple pieces of information to more accurately determine whether a driver's driving skills are unskilled, compared to cases where a judgment is made using only one of driver's license information, driving history information, and automobile insurance information. As a result, vehicle safety can be improved.

In addition, the driving skill inexperience determining unit 5 evaluates each piece of personal information with a score to create a driving skill point map, and determines whether the driver's driving skill is inexperienced based on the total score of each piece of personal information.

This makes it possible to make a comprehensive evaluation by combining each piece of personal information by making a judgment based on the total score, making it possible to more accurately judge whether the driver's driving skills are unskilled.

In addition, the driving skill inexperience determining section 5 determines whether to reflect the input information of the preventive safety function from the driver input acquisition section 4, depending on the operation targets such as vehicle acceleration, steering, and braking operations among the preventive safety functions. The configuration may be such that the judgment is made based on individual judgment criteria.

This makes it possible to set more detailed preventive safety functions depending on the driver, such as restricting the emergency braking function but not restricting the lane departure prevention function if the only past accident history is a rear-end collision with the vehicle in front. become.

Note that not only the types of preventive safety functions such as the emergency braking function and the lane departure prevention function, but also each setting item in the emergency braking function, for example, may be determined using individual criteria. The setting items include, for example, the front brake, rear brake, brake activation vehicle speed range, alarm volume, activation timing, etc. in the emergency brake function, and a plurality of items can be set for each operation target. This makes it possible to set more detailed preventive safety functions according to the setting items.

Embodiment 2.
Embodiment 2 of the present disclosure will be described using FIGS. 5 to 8. Differences from Embodiment 1 will be explained. Therefore, the items not explained are the same as in the first embodiment.

FIG. 5 is a block diagram showing the configuration of a vehicle control system according to Embodiment 2 of the present disclosure. As shown in FIG. 5, the vehicle control system according to the embodiment of the present disclosure includes a travel route management section 10 that acquires and manages travel route information based on input information from the driver input acquisition section 4.

Note that the driver input acquisition unit 4 of this embodiment accepts input of a destination in addition to ON/OFF settings for the preventive safety function. Further, the driving skill inexperience determining unit 5 of the present embodiment determines whether the driving skill of the driver is inexperienced based on the personal information from the personal information management unit 3 as well as the travel route information from the travel route management unit 10. to decide.

The driving route management section 10 will be explained in detail. The driving route management unit 10 acquires and manages a driving route from the current location to a destination set and input by the driver using the driver input acquisition unit 4, and various information regarding the driving route. For example, it manages traffic jam information such as whether there is a traffic jam on the driving route, the length of the traffic jam, the number of times the traffic jam occurs, and the location where the traffic jam is occurring.

The driving route management unit 10 may manage not only traffic congestion information but also information related to construction such as whether or not there is construction work on the driving route, length of section, number of times, location, number of lane reductions, etc. Furthermore, in addition to construction information, all kinds of information related to travel routes, such as accident information and moving object information, may be managed.

In addition, the driving route management unit 10 acquires and manages information not only from the driver input acquisition unit 4 but also from various sources such as car navigation systems, high-precision maps, road traffic information and communication systems, servers provided by car manufacturers, and the Internet. You may. Examples of the information to be acquired include GPS, map information, lane information, traffic jam information, construction information, and the like.

Next, the operation of the vehicle control system of this embodiment will be described in detail using the flowchart shown in FIG. Note that when the driver has not set the preventive safety function using the driver input acquisition unit 4, the preventive safety function is set to ON. Further, although the automatic emergency braking function is described here as an example, it is assumed that the same configuration applies to other preventive safety functions.

The vehicle control system first acquires personal information in the personal authentication section 2 and authenticates the driver. (Step S201)

Next, the personal information management section 3 manages the personal information corresponding to the driver authenticated by the personal authentication section 2, and transmits it to the driving skill inexperience judgment section 5 (step S202).

Next, the driver input acquisition unit 4 acquires input information regarding the preventive safety function from the driver (step S203).

Next, the driving route management unit 10 acquires driving route information from the current location to the destination (step S204).

Next, the preventive safety function control determination unit 5 determines whether the driver's driving skills are immature based on the driver's personal information acquired from the personal information management unit 3 and the driving route information acquired from the driving route management unit 10. The judgment is made and the input result is sent to the preventive safety function control unit 7 (step S205).

Next, the vehicle information acquisition section 6 acquires information regarding the vehicle and transmits it to the preventive safety function control section 7 (step S206).

Next, the preventive safety function control unit 7 receives the input results from the driving skill inexperience determining unit 5, the input information regarding the preventive safety function, and the information regarding the vehicle from the vehicle information acquisition unit 6, and uses the received information regarding the vehicle. Control calculations for the preventive safety function are performed (step S207).

Next, the driver notification unit 8 notifies the driver of the judgment information from the driving skill inexperience judgment unit 5, the warning from the emergency automatic brake, etc. (step S208).

Finally, the actuator 9 performs control related to acceleration, braking, and steering of the vehicle, such as brakes and electric power steering, based on control instructions from the preventive safety function control unit 5 (step S209).

Next, the driving skill inexperience determining section 5 at step 204 will be explained in detail. FIG. 7 is a flowchart showing the operation of the driving skill inexperience determining section 5 according to the second embodiment.

As shown in FIG. 7, the flowchart showing the operation of the driving skill inexperience determining unit 5 of the present embodiment is different from the flowchart of the first embodiment in that the operation is performed based on the driving route information from the driving route management unit 10. Steps S2043 and S2045 are added to determine whether the driver's driving skills are unskilled. In addition, in steps S2043 and S2045, even a good driver may have an inexperienced driving technique because an accident may occur in a congested area or a construction area.

In step S2043, based on the traffic congestion information from the travel route management unit 10, it is determined whether or not the driver's driving technique allows the driver to safely drive through the traffic jam. If it is determined that the driving technique is insufficient, even if the driver tries to turn off the emergency automatic braking function using the driver input acquisition unit 4, the OFF setting from the driver input acquisition unit 4 will be reflected in the active safety function control unit 5. (Step S2044).

Next, in step S2045, based on the construction information from the travel route management unit 10, it is determined whether the driver's driving skills can safely drive through the construction section. If it is determined that the driver's driving skills are unskilled, even if the driver attempts to set the emergency brake function to OFF using the driver input acquisition section 4, the OFF setting from the driver input acquisition section 4 will not be reflected in the active safety function control section 7. (Step S2044).

In this embodiment, traffic jam information and construction information are used to determine whether the driver's driving skills are unskilled, but any information managed by the driving route management unit 10 may be used. .

From the above description, the vehicle control system 1 of the present embodiment includes the driving route management unit 10 that manages driving route information regarding the driving route to the destination set and input by the driver using the driver input acquisition unit 4, The driving skill inexperience determining unit 5 determines whether the driver's driving skill is inexperienced based on information from the driving route management unit 10 in addition to personal information.

Thereby, in addition to the driver's personal information from the personal information management unit 3, it is possible to determine whether the driver's driving skills are unskilled by referring to external factors leading to the destination. Therefore, even if you are a good driver, with the active safety function limited, you can avoid accidents caused by unexpected traffic jams or construction work, and activate the active safety function more reliably. You can improve your sexuality.

Furthermore, the driving skill inexperience determining unit 5 determines whether the road is unfamiliar to the driver by combining driving route information and driving history information, and when it is determined that the road is unfamiliar to the driver, the driver input acquisition unit transmits information regarding the preventive safety function. The OFF setting may not be reflected. The criterion for determining whether the road is unfamiliar to the driver may be, for example, the presence or absence of a section where the driver is driving for the first time, or whether the number of times the driver has traveled is less than or equal to a certain threshold number of times.

This allows the preventive safety function to function reliably when traveling on a route for which the driver has little driving experience, thereby further improving the safety of the vehicle.

Next, a driving skill point map using driving route information will be explained. FIG. 8 is a table showing a driving skill point map of the driving skill inexperience determining unit 5 according to the second embodiment. Compared to the driving skill point map of the modified example of Embodiment 1, evaluation items such as length of congested section (maximum), length of construction section (maximum), number of traffic jams, and number of construction works are added. Furthermore, evaluation points are set in three stages from 1 to 3 points for each of the length of the congested section (maximum), the length of the construction section (maximum), the number of traffic jams, and the number of construction works.

In the driving skill point map of this embodiment, for example, when the total score H of driving skill points is 12 points or less, it is determined that the driving skill is unskilled. If the license classification is new, the number of accidents is 1, the insurance grade is 6th class, the maximum length of the congested section on the driving route is 3 km, the number of traffic jams is 2, the length of the construction section is 500 m, and the number of construction works is 1, the driving skill point will be Letting the total be H,
H=1+2+1+1+2+2+2=11<12
Since H is 12 points or less, it is determined that the driver's driving skills are immature.

By adding driving route information to the driving skill score map and determining whether or not a driver's driving skills are unskilled based on the total score, multiple personal information can be used to determine whether a driver's driving skills are unskilled or not. By finely defining and combining driving route information and driving route information, it is possible to more accurately judge whether the driver's driving skills are unskilled, and improve vehicle safety.
