Description

TECHNICAL FIELD

[0001] The present invention relates to a vehicle drive control system and a vehicle drive control method. STATE OF THE ART

[0002] In recent years, research and development of technologies for automatically driving a vehicle by a driving control system mounted on an automobile, independent of the operation of a driver, has been carried out (see, for example, JP 2016 - 215 658 A).

[0003] Meanwhile, there is a technology that uses a driver's pupil size or heartbeat to monitor the driver's alertness level and sends a periodic audio signal to the driver when the alertness level is low (see, for example, JP 2014 - 515 129 A ).

[0004] JP 2016-88497 A describes a vehicle drive control system configured to have a function for automatically driving a vehicle. It includes a control device configured to detect a brain wave or heartbeat of the driver and calculate a concentration index.

[0005] DE 10 2016 109 146 A1 describes a vehicle travel control device comprising a first information acquisition unit, a second information acquisition unit, a travel control device, a detector, and a computer. The first information acquisition unit acquires information about a driving environment of the host vehicle as driving environment information. The second information acquisition unit acquires information about the travel of the host vehicle as driving information. The travel control device performs evacuation travel control based on the driving environment information and the driving information. SUMMARY OF THE INVENTION TECHNICAL PROBLEM

[0006] When the vehicle is driven automatically by the system (automatic driving), thus relieving the driver of driving duties, the driver may become fatigued, and their concentration on driving (driving concentration) may decrease. In the event of a sudden event, such as a vehicle ahead suddenly decelerating and the distance between the vehicle ahead and the given vehicle suddenly decreasing, it is necessary to forcibly transfer the vehicle's driving authority from the system to the driver. However, if the driver's driving concentration is low, the driver may only perform a driving operation necessary for the transfer (drive switching) with a delay, which may make it difficult to transfer the vehicle's driving authority from the system to the driver safely and quickly.Therefore, even when the vehicle is driving automatically, it is important that the driver's concentration is maintained to a certain extent.

[0007] Meanwhile, to maintain a driver's concentration to a certain extent, it is necessary to accurately measure the driver's concentration. Since fatigue is a major factor causing a decrease in driving concentration, it is necessary to understand that driving concentration is closely related to driver fatigue, especially when the vehicle is driven automatically.

[0008] However, no method has been developed to calculate the driver's driving concentration taking into account the driver's fatigue.

[0009] It is an object of the present invention to provide a vehicle drive control system and a vehicle drive control method that can calculate the driving concentration of a driver of a vehicle with high accuracy and maintain the driving concentration of the driver to a certain extent even when the vehicle is automatically driven. SOLUTION TO THE PROBLEM

[0010] A vehicle drive control system according to the present invention for achieving the above-mentioned object is a vehicle drive control system having a function of automatically driving a vehicle.A control device that controls the driving control system performs control to detect a brain wave or a heartbeat of a driver of the vehicle during automatic driving of the vehicle, and uses a plurality of indices further correlated with the driver's fatigue, including indices related to the driver's brain wave or heartbeat, to calculate a concentration index that is an index indicating the driver's driving concentration at each preset control interval, wherein the control device is configured to perform control to work toward improving the driver's concentration by confirming, with the driver's cooperation, a continuation intention as to whether to continue automatic driving of the vehicle when the concentration index is equal to or greater than a preset concentration threshold.

[0011] A vehicle drive control method according to the present invention for achieving the above-mentioned object is a vehicle drive control method having a function for automatically driving a vehicle, in which control is performed to detect a brain wave or a heartbeat of a driver of the vehicle during automatic driving of the vehicle and use a plurality of indices further correlated with the driver's fatigue, including indices related to the driver's brain wave or heartbeat, to calculate a concentration index, which is an index indicating the driver's driving concentration, at every predetermined control interval, and control is performed so as to work towards improving the driver's concentration by confirming, with the driver's cooperation, a continuing intention thereto,whether the vehicle's automatic driving should continue if the concentration index is equal to or greater than a preset concentration threshold. ADVANTAGEOUS EFFECTS OF THE INVENTION

[0012] According to the present invention, since the brain wave or heartbeat of the driver of the vehicle is detected during the automatic driving of the vehicle, when the driver tends to feel tired (tends to drive inattentively), and the concentration index, which is the index indicating the driving concentration of the driver, is calculated by means of the plurality of indices closely related to the driver's fatigue, appropriate measures can be taken to maintain the driving concentration of the driver to a certain extent on the basis of the calculated concentration index, whereby the driving concentration of the driver can be maintained to a certain extent even during the automatic driving of the vehicle.

[0013] As a result, the driver's driving concentration is maintained to a certain extent, so that the driver can perform appropriate driving operations, and the vehicle's driving authority can be transferred safely and quickly when it is necessary to forcibly transfer the vehicle's driving authority from the system to the driver.

[0014] A vehicle drive control system and a vehicle drive control method according to the present invention will be described below based on an embodiment shown in the drawings. A vehicle having a vehicle drive control system 1 according to the present invention has an automatic driving function that enables the vehicle 3 to drive automatically based on the driving control system 1 without following a driver's driving operation. That is, either the driver or the driving control system 1 has the driving authority for the vehicle. As shown in Fig. 8, the vehicle is provided with a control device 2 that controls the driving control system 1.

[0015] In the present invention, the control device 2 performs control so as to detect a brain wave or heartbeat of the driver of the vehicle during automatic driving of the vehicle and uses a plurality of (two or more) indices further correlated with the driver's fatigue, including indices related to the driver's brain wave or heartbeat, to calculate a concentration index (composite index) CI, which is an index indicating the driver's driving concentration at each preset control interval (such as a time interval or a driving distance interval). As shown in Fig. As shown in Figure 1, the concentration index CI has a positive correlation with the intensity of the driver's fatigue, with the concentration index CI increasing as the intensity of the driver's fatigue increases.

[0016] A standard deviation of brainwave α waves, an average of brainwave β waves, an average of heartbeat peak intervals and a standard deviation of heartbeat peak intervals are used as the indices correlated with driver fatigue.

[0017] Brainwave α is a brainwave of 8 to 13 Hz, which mostly occurs when the driver is in a relaxed state. When the driver's consciousness is clear, the deviation of the brainwave α waves (standard deviation of the brainwave α waves) within a certain time (time set in advance according to experiments) is large. Meanwhile, when the driver's consciousness is uncertain and the driver feels tired, the standard deviation of the brainwave α waves is small. That is, as in Fig. As shown in Figure 2, the standard deviation of brainwave α waves has a negative correlation with driver fatigue, with the standard deviation of brainwave α decreasing as the intensity of driver fatigue increases.

[0018] Brainwave β is a brainwave of 13 to 25 Hz that usually occurs when the driver is in an active state (state of tension). As the driver's fatigue increases, the driver begins to exert himself to stay awake in order to shake off the fatigue. As fatigue increases, the effort to stay awake increases, thereby increasing the driver's state of tension. In such a state, the average of brainwave β within a certain time (average of brainwave β waves) increases. That is, as in Fig. As shown in Figure 3, the average of brainwave β-waves has a positive correlation with the driver’s fatigue.

[0019] Brainwave α and brainwave β are time series data of a target frequency obtained by passing brainwaves derived from a central part (Cz part) of the driver's brain through a bandpass filter using the international 10-20 method and calculating the activity of the target frequency. The international 10-20 method refers to a method in which measuring electrodes are arranged at equal intervals on the entire skull surface of a human (driver), while reference electrodes are arranged on the earlobes to measure a potential difference between the measuring electrodes and the reference electrodes.

[0020] The peak heartbeat interval refers to the interval between the peaks of adjacent heartbeat waves in an electrocardiogram. When the driver feels tired, the heartbeat is relatively low, causing the peak heartbeat interval to increase. That is, as in Fig. As shown in Figure 4, the peak heart rate interval has a positive correlation with the driver’s fatigue.

[0021] The standard deviation of the peak heart rate intervals is the variation of the peak heart rate intervals within a certain time. The peak heart rate intervals become larger when the driver feels tired, the fluctuations of the peak heart rate intervals become larger, and the standard deviation becomes larger. That is, as shown in Fig. As shown in Figure 5, the standard deviation of the peak interval of the heart rate has a positive correlation with the driver's fatigue.

[0022] By using the above four indices, that is, the standard deviation of the driver's brain wave α waves, the average of the brain wave β waves, the average of the peak intervals of the heartbeat and the standard deviation of the peak intervals of the heartbeat, when the indices are correlated with the driver's fatigue, the concentration index CI calculated as a composite index can be used as an index reflecting the driver's fatigue.

[0023] A method for calculating the concentration index CI is described. When the concentration index CI is calculated using four indices (the standard deviation of the driver's brainwave α waves, the average of the brainwave β waves, the average of the peak intervals of the heartbeat, and the standard deviation of the peak intervals of the heartbeat), an estimated value y of the concentration index CI is calculated, for example, by the following linear expression.This linear expression can be expressed as "y = a + α1 × x1 + α2 × x2 + α3 × x3 + α4 × x4", where a refers to an intercept value, x1 refers to the standard deviation of the brain wave α waves, x2 refers to the average value of the brain wave β waves, x3 refers to the average value of the peak intervals of the heartbeat, x4 refers to the standard deviation of the peak intervals of the heartbeat, and α1, α2, α3, and α4 refer to coefficients. Since a, α1, α2, α3, and α4 are fixed values ​​set in advance according to experiments or the like, the estimated value y of the concentration index CI is calculated by substituting the measured values ​​x1, x2, x3, and x4 into this linear expression. The coefficient α1 is a negative value.

[0024] As in Fig. As shown in Figure 6, an estimated value y1 of the calculated concentration index CI and an evaluation value, which is an estimated value for the intensity of the driver's fatigue based on the driver's facial expression, are transition lines that are approximately estimated. A correlation coefficient between the two estimated values ​​can be approximately 0.7, with a strong positive correlation between them.

[0025] As described above, in the present invention, since the concentration index CI, which is the index indicating the driving concentration of the driver, is calculated by means of the plurality of indices closely correlated with the driver's fatigue during automatic driving of the vehicle, when the driver tends to feel tired (tendency of distracted driving), appropriate measures can be taken that will maintain the driver's driving concentration to some extent on the basis of the calculated concentration index CI.

[0026] In addition to the above four indices, the concentration index CI can be calculated using a biological index of another driver and the driver's image analysis information. In this case, the estimated value y of the concentration index CI is calculated using a linear expression of "y = a + α1 × x1 + α2 × x2 + α3 × x3 + α4 × x4 + α5 × x5 + α6 × x6", where x5 refers to the driver's biological index, x6 refers to the driver's image analysis information, and α5 and α6 refer to coefficients.

[0027] For example, the biological index can be a change in the pressure of the driver's seat. When a change in body pressure distribution is obtained by a pressure sensor embedded in the driver's seat, it is assumed that the driver is tired and in a state of low physical activity, i.e., the change in pressure is small. At this time, as the driver feels tired, the amount of pressure change decreases, and there is a negative correlation with the driver's fatigue.

[0028] Driver image analysis information is information obtained by analyzing a photo of the driver's face taken by a camera or the like mounted around a driver's seat of the vehicle. For example, when the driver's eyelid movement is detected and their eyes are more closed due to fatigue, a value of the image analysis information decreases. This means that the driver image analysis information has a negative correlation with driver fatigue.

[0029] Next, a description will be given of the control performed by the control device 2 when it is determined that the driver feels tired based on the calculated concentration index CI. The control device 2 performs control to confirm, with the driver's cooperation, a continuation intention as to whether to continue the automatic driving of the vehicle and to work to improve the driver's concentration when the estimated value y of the concentration index CI is equal to or greater than the preset concentration threshold value y1. In this way, by confirming the continuation intention of the automatic driving of the vehicle with the driver's cooperation, the driver's fatigue can be eliminated while maintaining the driver's concentration to a certain extent.

[0030] Confirmation of the intention to continue automatic driving of the vehicle is a notification from a voice device installed at the driver's seat of the vehicle to the driver through voice or text displayed on a text display panel. For example, if a drop in the driver's concentration is detected, a message such as "Low driver concentration has been detected. To continue automatic driving, please press the automatic driving continuation switch" is delivered to the driver to confirm the intention to continue. After the driver presses the automatic driving continuation switch, a message such as "The intention to continue automatic driving has been confirmed. Automatic driving will continue" is delivered to the driver.

[0031] The control device 2 performs control such that fuel injection into an engine (in the case of an internal combustion engine) provided in the vehicle is stopped and automatic driving of the vehicle is canceled when the driver does not perform an operation such as pressing a certain switch, the continuation intention remaining in an unconfirmed state for a preset first setting time t1 since the continuation intention of the automatic driving of the vehicle with the driver is confirmed.

[0032] In this way, by stopping fuel injection into the engine and canceling the automatic driving of the vehicle, the vehicle gradually decelerates, thereby enabling the driver to shake off fatigue and perform an operation to indicate the intention to continue the automatic driving. As a result, the automatic driving of the vehicle can be resumed in a state where the driver's concentration is maintained to a certain extent, and the automatic driving can continue.

[0033] The control device 2 performs control to illuminate an emergency flashing lamp (warning lamp) of the vehicle and the brake and forcibly stop the vehicle when the driver performs no operation such as pressing the corresponding switch, with the continuation intention remaining in the unconfirmed state for a preset second setting time t2 since the automatic driving of the vehicle is canceled, or when a speed v of the vehicle drops below a preset vehicle speed v1. It should be noted that after the emergency flashing lamp is illuminated, it is preferable to automatically stop the vehicle for safety reasons even if there is an operation from the driver.

[0034] In this way, if you don't get an appropriate response from the driver, even if the vehicle is gradually decelerated, the vehicle's emergency flashing light will light up, braking and forcibly stopping the vehicle, so that the vehicle will not be driven into a state where the driver feels tired, and accidents such as a collision between the vehicle in question and objects such as another vehicle can be avoided.

[0035] As described above, by taking appropriate measures based on the concentration index CI calculated by reflecting the driver's fatigue, even when the vehicle is driven automatically, the driver's driving concentration can be maintained to a certain extent. This maintains the driver's driving concentration to a certain extent, allowing the driver to perform appropriate driving operations. When it is necessary to forcibly transfer the driving authority from the system to the driver, the driving authority of the vehicle can be transferred safely and quickly.

[0036] Next, a vehicle drive control method according to the present invention based on the vehicle drive control system 1 will be described with reference to a control flow of Fig. 7. The control sequence of Fig. 7 is a control flow executed from a previous control flow each time a preset control interval elapses during automatic driving of the vehicle.

[0037] If the control sequence of Fig.7 is started, the estimated value y of the driver's concentration index CI is calculated in step S10. After the control of step S10 is performed, the process proceeds to step S20. In step S20, it is determined whether the estimated value y calculated in step S10 is equal to or greater than the concentration threshold y1. If the estimated value y is less than the concentration threshold y1 (NO), the process returns and the control flow is terminated. Meanwhile, if the estimated value y is equal to or greater than the concentration threshold y1 (YES), the process proceeds to step S30, where in step S30, the continuation intention of whether to continue the automatic operation of the vehicle is confirmed with the driver to improve the driver's concentration. After the control of step S30 is performed, the process proceeds to step S40.

[0038] In step S40, it is determined whether the preset first setting time t1 has elapsed since the driver's intention to continue automatic driving of the vehicle was confirmed, with the driver not performing any operation such as pressing the specified switch and the intention to continue remaining in the unconfirmed state. If the first setting time t1 has not elapsed (NO), the process returns and the control flow is terminated. Conversely, if the first setting time t1 has elapsed (YES), the process proceeds to step S50, where, in step S50, fuel injection to the engine is stopped and automatic driving of the vehicle is canceled. After the control of step S50 is performed, the process proceeds to step S60.

[0039] In step S60, it is determined whether the driver performs no operation such as pressing the specified switch while the continuation intention remains in the unconfirmed state since the automatic driving of the vehicle was canceled. This determination is made based on whether the preset second setting time t2 has elapsed since the automatic driving of the vehicle was canceled while the continuation intention remains in the unconfirmed state, or whether the vehicle speed v drops below the preset vehicle speed v1. If the continuation intention of the automatic driving is confirmed (NO), the process returns and the control flow is terminated.If, however, the intention to continue automatic driving is not confirmed (YES), the process proceeds to step S70, where, in step S70, the vehicle's emergency flashing light (warning light) is illuminated, and the vehicle is braked and forcibly stopped. After the control of step S70 is performed, the process returns and the control flow is terminated.

[0040] As described above, the vehicle drive control method based on the vehicle drive control system 1 according to the present invention is a vehicle drive control method having a function of automatically driving a vehicle, in which control is performed such that the brain wave or heartbeat of the driver of the vehicle is detected during the automatic driving of the vehicle, and the plurality of indexes are used that are further correlated with the fatigue of the driver among the indexes related to the brain wave or heartbeat of the driver to calculate the concentration index CI that is the index indicating the driving concentration of the driver at each preset control interval.

[0041] According to this method, the same effect as in the vehicle drive control system 1 of the vehicle can be achieved.

[0042] In the above description, attention is paid to the control device 2 provided in the driving controller 1, and the function realized by the control device 2 and the processing executed by the control device 2 are described.

[0043] Specifically, the control device 2 can be implemented, for example, by the following configuration.

[0046] The interface comprises a communication module configured to communicate with the various devices and may be connected to the various devices by a wired connection, for example by comprising a connector, or may be connected to the various devices wirelessly, for example by comprising a wireless communication module.

[0047] The memory may comprise a semiconductor memory device such as a rewritable DRAM or EPROM, or a non-rewritable ROM, or may comprise a storage device such as a hard disk.

The controller can be configured, for example, by a processor and can be configured to perform a series of processing operations by executing a program stored in memory, or it can be configured as hardware, such as an ASIC, and can be configured to perform a predetermined series of processing operations.

[0049] The controller repeats the following processing for each preset control interval while the vehicle is automatically driven: retrieving a biological index signal outputted from the biological index sensor among the devices that detects the brain wave or heart rate of the driver of the vehicle, detecting the brain wave or heart rate of the driver based on the retrieved biological index signal, calculating a plurality of biological indices correlated with the fatigue of the driver based on the detected brain wave or heart rate of the driver, and using at least two of the plurality of calculated biological indices to calculate the concentration index, which is the index indicative of the driving concentration of the driver.
