The erroneous start control device and the erroneous start control method according to the second embodiment will be described. The second embodiment is a subordinate concept of the first embodiment. The erroneous start control device according to the second embodiment includes each configuration of the erroneous start control device 100 shown in the first embodiment. The same configuration and operation as in the first embodiment will not be described.

FIG. 5 is a block diagram showing a configuration of an erroneous start control device 101 and a device that operates in connection with the erroneous start control device 101 according to the second embodiment. The erroneous start control device 101 includes a distance acquisition unit 10, a traveling direction acquisition unit 20, and an alarm output control unit 30. Further, FIG. 5 shows a distance sensor 120, a camera 130, a gear 140, and a speaker 111 as devices that operate in connection with the erroneous start control device 101.

FIG. 6 is a diagram showing the relationship between the erroneous start control device 101 according to the second embodiment and the device provided in the vehicle 1. Here, the erroneous start control device 101 is mounted on the vehicle 1.

The distance sensor 120 is provided in the vehicle 1. The distance sensor 120 measures the distance between the driver's foot 2A of the vehicle 1 and the accelerator pedal 150. The driver's foot 2A is the foot of the driver 2, for example, the sole of the foot of the driver 2 (that is, the sole of the shoe) that operates the accelerator pedal 150 or the tip of the foot of the driver 2 (that is, the shoe). Beyond). The distance sensor 120 may be a distance measurement camera.

The distance acquisition unit 10 acquires the distance between the driver's foot 2A of the vehicle 1 and the accelerator pedal 150 measured by the distance sensor 120.

The camera 130 is mounted on the vehicle 1 and captures an image of the driver 2. The image of the driver 2 includes, for example, an image of the face of the driver 2 or an image of the eyes of the driver 2.

The gear 140 is provided in the vehicle 1 and is operated by the shift lever 141.

The traveling direction acquisition unit 20 acquires the first traveling direction estimated based on the image of the driver 2 taken by the camera 130. When the traveling direction acquisition unit 20 estimates the first traveling direction by itself, the traveling direction acquisition unit 20 first acquires an image of the driver 2's face taken by the camera 130. Then, the traveling direction acquisition unit 20 estimates the first traveling direction based on the direction of the driver 2's face or the direction of the line of sight in the image of the driver 2.

For example, when the driver 2's face or line of sight is facing the front of the vehicle 1 through the windshield (not shown) of the vehicle 1, the traveling direction acquisition unit 20 determines that the first traveling direction is the front. presume. Or, for example, when the driver 2's face or line of sight is facing the rear of the vehicle 1, the monitor showing the rear image of the vehicle 1 is facing, or the rearview mirror is facing, the direction of travel is acquired. The unit 20 estimates that the first traveling direction is rearward. The first traveling direction thus estimated corresponds to the traveling direction intended by the driver 2 of the vehicle 1.

Further, the traveling direction acquisition unit 20 acquires the second traveling direction detected based on the shift information of the vehicle 1. The traveling direction acquisition unit 20 may detect the position of the shift lever 141 or the position of the gear 140 as the shift information of the vehicle 1.

In the second embodiment, the traveling direction acquisition unit 20 detects the second traveling direction when the shift information is drive or reverse. For example, when the shift information based on the position of the shift lever 141 is drive, the second traveling direction is forward. Alternatively, for example, when the shift information based on the position of the shift lever 141 is reverse, the second traveling direction is backward. The second traveling direction detected in this way corresponds to the direction in which the vehicle 1 travels by driving the driving device (not shown) of the vehicle 1. For example, the second traveling direction corresponds to the direction in which the vehicle 1 travels when the driver 2 depresses the accelerator pedal 150. Alternatively, for example, the second traveling direction corresponds to the direction in which the vehicle 1 equipped with the automatic transmission travels due to the creep phenomenon.

The alarm output control unit 30 determines that the distance between the driver's foot 2A and the accelerator pedal 150 is within a predetermined distance, and the information in the first traveling direction and the information in the second traveling direction do not match. , Controls to output an alarm to the speaker 111.

When the shift information based on the position of the shift lever 141 is neutral or parking, the traveling direction acquisition unit 20 does not detect the second traveling direction because there is no possibility of erroneous starting. That is, the alarm output control unit 30 does not control the notification device 110 to output an alarm when the shift information is neutral or parking, and the notification device 110 when the shift information is drive or reverse. Controls to output an alarm to.

The speaker 111 is a notification device 110 and is provided in the vehicle 1. The speaker 111 outputs an alarm by voice under the control of the alarm output control unit 30. Further, a display device (not shown) may be provided in the vehicle 1 as the notification device 110, and in that case, the alarm output control unit 30 controls the display device to display an alarm.

FIG. 7 is a flowchart showing the operation of the erroneous start control device 101 and the erroneous start control method according to the second embodiment.

In step S10, the distance acquisition unit 10 acquires the distance between the driver's foot 2A and the accelerator pedal 150 from the distance sensor 120.

In step S20, the traveling direction acquisition unit 20 estimates the first traveling direction based on the image of the driver 2 taken by the camera 130. The traveling direction acquisition unit 20 estimates the first traveling direction based on the direction of the driver 2's face or the direction of the line of sight in the image of the driver 2. For example, when the driver 2's face or line of sight is facing the front of the vehicle 1 through the windshield of the vehicle 1, the traveling direction acquisition unit 20 estimates that the first traveling direction is the front. Or, for example, when the driver 2's face or line of sight is facing the rear of the vehicle 1, the monitor showing the rear image of the vehicle 1 is facing, or the rearview mirror is facing, the direction of travel is acquired. The unit 20 estimates that the first traveling direction is rearward.

In step S30, the traveling direction acquisition unit 20 detects the second traveling direction based on the shift information of the vehicle 1. For example, when the shift information based on the position of the shift lever 141 is drive, the second traveling direction is forward. Alternatively, for example, when the shift information based on the position of the shift lever 141 is reverse, the second traveling direction is backward.

In step S40, the alarm output control unit 30 determines whether or not the distance between the driver's foot 2A and the accelerator pedal 150 is within a predetermined distance. When the distance between the driver's foot 2A and the accelerator pedal 150 is within a predetermined distance, there is a high possibility that the driver 2 depresses the accelerator pedal 150. Therefore, if the distance is within a predetermined distance, step S50 is executed. If the distance is not within a predetermined distance, the erroneous start control method ends.

In step S50, the alarm output control unit 30 determines whether or not the information in the first traveling direction and the information in the second traveling direction do not match. If the information in the first traveling direction and the information in the second traveling direction do not match, there is a high possibility that the vehicle will start erroneously. Therefore, if the information in the first traveling direction and the information in the second traveling direction do not match, step S60 is executed. When the information in the first traveling direction and the information in the second traveling direction match, the erroneous start control method ends.

In step S60, the alarm output control unit 30 controls the notification device 110 to output an alarm. Here, the alarm output control unit 30 controls the speaker 111 to output an alarm.

In step S70, the speaker 111 outputs an alarm by voice.

The erroneous start control device 101 shown above controls the speaker 111 to output an alarm regarding erroneous start before the driver 2 of the vehicle 1 depresses the accelerator pedal 150. The speaker 111 notifies the driver 2 by voice before the vehicle 1 starts to move. The driver 2 recognizes the alarm and stops the operation of depressing the accelerator pedal 150. Therefore, the erroneous start control device 101 can accurately prevent the erroneous start of the vehicle 1. Further, when the vehicle 1 moves in a direction opposite to the direction intended by the driver 2, the driver 2 is surprised at the movement. The erroneous start control device 101 can reduce the burden on the driver 2.

Further, the alarm output control unit 30 of the erroneous start control device 101 according to the second embodiment controls to output an alarm when the shift information of the vehicle 1 is drive or reverse.

With such a configuration, the erroneous start control device 101 can accurately prevent the erroneous start of the vehicle 1.

<Embodiment 3>
The erroneous start control device and the erroneous start control method according to the third embodiment will be described. The third embodiment is a subordinate concept of the first embodiment. The erroneous start control device according to the third embodiment includes each configuration of the erroneous start control device 100 shown in the first embodiment. The description of the configuration and operation similar to those of the first or second embodiment will be omitted.

FIG. 8 is a block diagram showing a configuration of the erroneous start control device 102 according to the third embodiment and a device that operates in connection therewith.

The erroneous start control device 102 further includes a start control unit 40 in addition to the configuration shown in the second embodiment. Further, FIG. 8 further shows the accelerator pedal 150 as a device that operates in connection with the erroneous start control device 102.

Similar to the second embodiment, the alarm output control unit 30 has the distance between the driver's foot 2A and the accelerator pedal 150 within a predetermined distance, and the information on the first traveling direction and the second traveling direction. When the information does not match, the speaker 111 is controlled to output an alarm. The alarm output control unit 30 according to the third embodiment further controls the start control unit 40 to invalidate the operation of the accelerator pedal 150 when the alarm is output.

The start control unit 40 has a function of preventing erroneous operation of the accelerator pedal 150 provided in the vehicle 1. The opening degree of the accelerator pedal 150 is detected by, for example, a position sensor (not shown). The engine control unit (ECU) (not shown) of the vehicle 1 controls the output of the engine (not shown) based on the detection result. The same applies when the vehicle 1 is an electric vehicle. For example, the power control unit (ECU) (not shown) of the vehicle 1 controls a motor (not shown) based on the detection result of the position sensor. The start control unit 40 invalidates the operation of the driver 2 with respect to the accelerator pedal 150 under the control of the alarm output control unit 30. Therefore, even when the accelerator pedal 150 is depressed by the control of the start control unit 40, the ECU does not increase the output of the engine. In this way, the start control unit 40 prevents erroneous operation of the accelerator pedal 150. The start control unit 40 may be included in the ECU or the PCU, for example. Alternatively, for example, the start control unit 40 may be a device different from the ECU or the PCU.

FIG. 9 is a flowchart showing the operation of the erroneous start control device 102 and the erroneous start control method according to the third embodiment.

Up to step S70 is the same as each step shown in FIG.

In step S80, the alarm output control unit 30 controls the start control unit 40 to invalidate the operation on the accelerator pedal 150.

In step S90, the start control unit 40 invalidates the operation on the accelerator pedal 150.

Summarizing the above, the erroneous start control device 102 according to the third embodiment further includes a start control unit 40 that prevents erroneous operation of the accelerator pedal 150. When the alarm output control unit 30 outputs an alarm, the alarm output control unit 30 controls the start control unit 40 to invalidate the operation of the accelerator pedal 150.

With the above configuration, the erroneous start control device 102 can disable the accelerator pedal 150 before the driver 2 of the vehicle 1 depresses the accelerator pedal 150. The erroneous start control device 102 can accurately prevent the erroneous start of the vehicle 1.

<Embodiment 4>
The erroneous start control device and the erroneous start control method according to the fourth embodiment will be described. The fourth embodiment is a subordinate concept of the first embodiment. The erroneous start control device according to the fourth embodiment includes each configuration of the erroneous start control device 100 shown in the first embodiment. The same configuration and operation as any of the first to third embodiments will be omitted.

Due to the intentional operation of the driver 2, a state in which the first traveling direction and the second traveling direction do not match may occur for a short time. For example, when the shift information is drive, the second traveling direction is forward. When the driver 2 confirms the rear in that state, the first traveling direction is the rear in a short time of the rear confirmation. At the time of checking backward, the speaker 111 outputs an alarm because the first traveling direction and the second traveling direction do not match. When the erroneous start control device performs such control, an alarm is output every time the driver 2 confirms the rear. Similarly, when turning left or right, the driver 2 confirms the left direction, the right direction, or the rear side in order to prevent pedestrians and the like from being involved. In that case as well, a discrepancy between the first traveling direction and the second traveling direction occurs due to the confirmation operation of the driver 2, and an alarm is output. In particular, when the vehicle 1 is equipped with a manual transmission, the above-mentioned problems occur remarkably. In order to improve the accuracy of the control for suppressing erroneous start, it is preferable that the frequency of alarm output due to the intentional confirmation operation of the driver 2 is low. The erroneous start control device according to the fourth embodiment has a configuration for solving such a problem.

FIG. 10 is a block diagram showing a configuration of an erroneous start control device 103 and a device that operates in connection with the erroneous start control device 103 according to the fourth embodiment.

The erroneous start control device 103 has a mismatch time measuring unit 31 in the alarm output control unit 30. Other configurations of the erroneous start control device 103 are the same as those of the erroneous start control device 101 shown in the second embodiment.

The mismatch time measuring unit 31 measures the duration of a state in which the information in the first traveling direction and the information in the second traveling direction do not match, that is, the mismatched state.

The alarm output control unit 30 controls to output an alarm when the duration of the mismatch state measured by the mismatch time measurement unit 31 elapses for a predetermined time or longer.

FIG. 11 is a flowchart showing the operation of the erroneous start control device 103 and the erroneous start control method according to the fourth embodiment.

Up to step S50 is the same as each step shown in FIG. However, when it is determined in step S50 that the alarm output control unit 30 is in a mismatched state, the alarm output control unit 30 records the time in a storage unit (not shown) included in the erroneous start control device 103.

In step S55, the alarm output control unit 30 determines whether or not the mismatched state continues for a predetermined time or longer. For example, the alarm output control unit 30 determines whether or not the mismatched state continues for a predetermined time or longer based on the time recorded in the storage unit. If the mismatch state continues for a predetermined time or longer, step S60 is executed. If the mismatch state does not continue for a predetermined time or longer, step S10 is executed again.

The steps after step S60 are the same as those of each step shown in FIG.

Summarizing the above, the alarm output control unit 30 of the erroneous start control device 103 according to the fourth embodiment has continued the state in which the information in the first traveling direction and the information in the second traveling direction do not match for a predetermined time or longer. In this case, control is performed to output an alarm.

With the above configuration, the erroneous start control device 103 can be controlled so that the alarm is not output in a short-time mismatch state caused by the confirmation operation of the driver 2. As a result, the accuracy of the suppression control of erroneous start is improved. Further, the erroneous start control device 103 eliminates the annoyance felt by the driver 2 in response to the alarm caused by the confirmation operation of the driver 2.

<Embodiment 5>
The erroneous start control device and the erroneous start control method according to the fifth embodiment will be described. The fifth embodiment is a subordinate concept of the first embodiment. The erroneous start control device according to the fifth embodiment includes each configuration of the erroneous start control device 100 shown in the first embodiment. The same configuration and operation as any of the first to fourth embodiments will be omitted.

If the distance between the driver's foot 2A and the accelerator pedal 150 continues to be within a predetermined distance, the alarm continues to sound. For example, even if the driver 2 does not try to depress the accelerator pedal 150, the alarm continues to sound if the driver's foot 2A continues to be close to the accelerator pedal 150. Alternatively, for example, in the normal posture of the driver 2, the alarm sounds even when the position of the driver's foot 2A is close to the accelerator pedal 150. In order to improve the accuracy of the control for suppressing erroneous start, it is preferable that the frequency of alarm output is low in such a situation. The erroneous start control device according to the fifth embodiment has a configuration for solving such a problem.

The configuration of the erroneous start control device according to the fifth embodiment is the same as that of the erroneous start control device 101 shown in the second embodiment.

FIG. 12 is a flowchart showing the operation of the erroneous start control device and the erroneous start control method according to the fifth embodiment.

Up to step S40 is the same as each step shown in FIG. However, if the alarm output control unit 30 determines in step S40 that the distance between the driver's foot 2A and the accelerator pedal 150 is within a predetermined distance, the alarm output control unit 30 performs erroneous start control. The distance between the driver's foot 2A and the accelerator pedal 150 is recorded in the storage unit of the device.

In step S45, the alarm output control unit 30 determines whether or not the driver's foot 2A and the accelerator pedal 150 are close to each other. For example, the alarm output control unit 30 reads the distance recorded in the storage unit, that is, the distance acquired last time. Then, the alarm output control unit 30 determines whether or not the driver's foot 2A is approaching the accelerator pedal 150 based on the distance acquired last time and the distance acquired this time. If the distance is approaching, step S50 is executed. If the distance is not close, step S10 is executed again.

The steps after step S50 are the same as those of each step shown in FIG.

Summarizing the above, the alarm output control unit 30 of the erroneous start control device according to the fourth embodiment outputs an alarm when the distance between the driver's foot 2A and the accelerator pedal 150 is approaching with the passage of time. I do.

With the above configuration, the erroneous start control device can control the alarm caused by the position of the driver's foot 2A so that the driver 2 does not output an unintended alarm. As a result, the accuracy of the suppression control of erroneous start is improved. The erroneous start control device eliminates the annoyance felt by the driver 2 in response to an unnecessary warning caused by the position of the driver's foot 2A.
