Description

  The present invention relates to a driving support device, and more particularly to a driving support device capable of accurately traveling a desired position on a road and recognizing in advance whether an obstacle on the road is stepped on with a left wheel or a right wheel. About.

When driving a car that cannot be ridden normally, such as a rental car, or when a novice driver is driving a vehicle, is it difficult to recognize the position (vehicle sense) of the vehicle relative to the road on which the vehicle is traveling, and is the vehicle traveling in the center of the road? I'm worried that I'm not driving around the road. Also, if there are small obstacles on the road (such as empty cans or unidentified ones), the driver is worried that the wheels will not step on the obstacles. In order to avoid obstacles without fail, the driver may bring the vehicle closer to the oncoming lane or sidewalk more than necessary, which is dangerous for oncoming vehicles and pedestrians.
As a conventional technology of a driving support device for facilitating recognition of the position of the host vehicle with respect to the road on which it travels, as shown in Japanese Patent Application Laid-Open No. 2004-203130 and Japanese Patent Application Laid-Open No. 2000-16325, There is an indicator provided to inform the driver of the passing position of the left and right wheels of the host vehicle.

However, as shown in Patent Document 1 and Patent Document 2, display marks and display devices composed of a sticker-attached seal change the height of the eye point (viewpoint) when the driver changes, so the position of the display mark is also changed. It will change and cannot be used as it is. The display mark is troublesome to remove and change, and the display mark combined with another driver rather hinders driving. Further, in order to grasp the correct installation position, the driver needs to be in the driving position (sitting in the driver's seat and taking a normal driving posture).
In addition, the driver must move his body to install the display mark, and the eye point will fluctuate, so it is not possible to install the display mark on the dashboard alone while arriving at the driving position. . Therefore, with the help of the third person, the third person installs a display mark according to the driver's instruction, or the driver breaks the driving position and installs the display mark at an approximate position, After confirming the display mark position, correct the deviation and re-install.
Therefore, in the driving assistance devices of Patent Document 1 and Patent Document 2, it is difficult for the driver alone to install the display mark at an accurate position. Further, when the display mark is shifted, the display mark cannot be easily re-installed. As a calibration method, drawing a white line on the road and placing a display mark on the vehicle or bringing the vehicle to the existing white line for marking is very laborious and difficult to calibrate.

  The present invention provides a driving support device capable of accurately traveling a position desired to travel on a road such as traveling around the center of a road and recognizing in advance whether an obstacle on the road is stepped on with a left wheel or a right wheel. It aims to be realized.

  The present invention relates to a light emitting device provided at equal intervals from the left end to the right end of the upper surface of the instrument panel in a driving support device provided in the vehicle so that the driver can easily recognize the position of the host vehicle with respect to the road on which the driver is driving. And a lighting setting means that is provided at a position where the driver can operate in a normal driving posture and can be set so that only the light-emitting body necessary for the driver to drive is lit. It is characterized by that.

The driving support device according to the present invention sets the lighting body at a position for recognizing the position of the host vehicle in a normal driving posture, for example, the lighting body corresponding to the center position of the vehicle to light. The person can easily recognize the center of the road while the vehicle is traveling.
The driving support device according to the present invention is set so that a light emitting body in a position for recognizing the position of the host vehicle in a normal driving posture, for example, a light emitting body corresponding to a position through which the left and right wheels pass is set. Thus, the driver can easily recognize in advance whether the left and right wheels pass through the obstacle on the road while the vehicle is traveling. Therefore, the driver can avoid an obstacle with a minimum steering operation. Therefore, the driver does not have to bring the vehicle closer to the opposite lane or the sidewalk than necessary.
In the driving support device of the present invention, since the driver can set the lighting body to be turned on / off in a normal driving posture, the driver can set the lighting body to be turned on / off accurately. The lighting position of the light emitter can be confirmed while sitting in the seat. Further, the driving support device of the present invention can easily set the light emitters to be turned on / off even when the driver is replaced.

In FIG. 1, 1 is a road, 2 is a host vehicle, 3 is a windshield, 4 is an instrument panel, 5 is a center panel, 6 is a steering handle, 7 is a left wheel, and 8 is a right wheel. When the driver drives the vehicle 2 on the road 1, the driver sits on the driver's seat and drives the steering wheel 6 by steering the left wheel 7 and the right wheel 8. The own vehicle 2 is provided with a driving support device 9 so that the driver can easily recognize the position of the own vehicle 1 with respect to the road 1 on which the driver is driving.
As shown in FIG. 2, the driving support device 9 includes light emitters A <b> 1 to An provided at equal intervals from the left end to the right end of the upper surface of the instrument panel 4 adjacent to the lower end of the windshield 3, and the driver is in the driver's seat. And a lighting setting means 10 which is provided at a position where the driver can operate in a normal driving posture and which can be set so that only the light emitter A necessary for driving by the driver is turned on. Yes.
The plurality of light emitters A1 to An are, for example, LEDs. The lighting setting unit 10 includes an operation switch unit 11 and a setting processing unit 12. The operation switch unit 11 includes a first switch 13 that outputs a lighting signal to the setting processing unit 12 by a pressing operation, and a second switch 14 that outputs a confirmation signal to the setting processing unit 12 by a pressing operation. As shown in FIG. 1, the operation switch unit 11 is installed on the center panel 5 that can be operated by a driver reaching out in a normal driving posture. The light emitters A1 to An are connected to the setting processing unit 12. Each time the lighting signal is input from the first switch 13, the setting processing unit 12 turns on only one of the plurality of light emitters A in order of the light emitters A 1, A 2, A 3,. In addition, when a determination signal is input from the second switch 14, the setting processing unit 12 determines the lighting of the light emitter A that is currently emitting light. In FIG. 2, reference numeral 15 is a power source, and reference numeral 16 is ground.

As shown in FIG. 1, the driving support device 9 stops the host vehicle 2 on the road 1. For example, first, the driving support device 9 can grasp the positional relationship between the vehicle center position 2 </ b> C of the host vehicle 2 and the center 1 </ b> C of the road 1. To. The driver switches the first switch until the light-emitting body A28 corresponding to the vehicle center position 2C that overlaps with the extension line of the center 1C of the road 1 is turned on with the viewpoint S aligned with the center 1C of the road 1 in the normal driving posture seated in the driver's seat. 13 is repeatedly pressed, and the second switch 14 is pressed while the light emitter A28 is lit. Thereby, the lighting setting means 10 determines the lighting of the light emitter A28 corresponding to the vehicle center position 2C.
Next, the driving support device 9 makes it possible to grasp the positional relationship between the position 7C through which the left wheel 7 of the host vehicle 2 passes and the road 1. The driver repeats the first switch 13 until the light-emitting body A17 corresponding to the position 7C through which the right wheel 7 passes is turned on by aligning the viewpoint S with the position 7C through which the right wheel 7 passes in the normal driving posture seated in the driver's seat. The second switch 14 is pressed while the light emitter A17 is lit. Thereby, the lighting setting means 10 determines lighting of the light emitter A17 corresponding to the position 7C through which the left wheel 7 passes.
Furthermore, the driving assistance device 9 makes it possible to grasp the positional relationship between the position 8C through which the right wheel 8 of the host vehicle 2 passes and the road 1. The driver repeats the first switch 13 until the light-emitting body A41 corresponding to the position 8C through which the right wheel 8 passes is turned on by aligning the viewpoint S with the position 8C through which the left wheel 8 passes in the normal driving posture seated in the driver's seat. The second switch 14 is pressed while the light emitter A41 is lit. Thereby, the lighting setting means 10 determines lighting of the light emitter A41 corresponding to the position 8C through which the right wheel 8 passes.

As described above, the driving support device 9 turns on the light emitter A at the position for recognizing the position of the host vehicle 2 in the normal driving posture, for example, the light emitter A28 corresponding to the vehicle center position 2C. By setting with the lighting setting means 10, the driver can easily recognize the center of the road 1 while the vehicle is traveling.
In addition, the driving support device 9 is configured such that the driver is in a normal driving posture and the light emitter A at a position for recognizing the position of the host vehicle 2, for example, the light emitter A17 corresponding to the position through which the left and right wheels 7 and 8 pass. By setting the lighting setting means 10 to light A41, the driver can easily recognize in advance whether the left and right wheels 7 and 8 pass the obstacle B on the road 1 while the vehicle is traveling. Therefore, the driver can avoid the obstacle B with the minimum steering operation of the steering handle 6. Therefore, the driver does not have to bring the host vehicle 2 closer to the opposite lane or the sidewalk than necessary.
Furthermore, since the driver can set the lighting A to be turned on / off in a normal driving posture, the driver can set the lighting A to be turned on / off accurately by one driver. The lighting position of the light emitter A can be confirmed while staying in the driver's seat. Further, the driving support device 9 can easily set the light emitter A to be turned on / off even when the driver is replaced.

The driving support device 9 includes a calibration sheet 17 as shown in FIG. 4 in order to accurately set the vehicle center position 2C and the positions 7C and 8C through which the left and right wheels 7 and 8 pass in a short time. The calibration sheet 17 is a rectangular sheet in which the length L1 of the horizontal side W is the tread width of the left and right wheels 7 and 8 of the host vehicle 2, and the length L2 of the vertical side H is equal to or greater than the total length of the host vehicle 2. It consists of 18. On this sheet 18, a center line 17C is drawn from the center of one lateral side W to the center of the other lateral side W, and one longitudinal side H has a certain range (1/4 of the longitudinal side H). The protrusions 19 such as ridges are arranged in a band shape over a certain extent.
As shown in FIGS. 5 and 6, the lighting setting means 10 first has a center line 17 </ b> C drawn on the road surface 20 in front of the host vehicle 2 in a private parking lot or the like, and a protrusion 19 on one vertical side H. Is placed on the calibration sheet 17, and secondly, the host vehicle 2 disposed facing one lateral side W of the calibration sheet 17 travels toward the other lateral side W and is disposed on the calibration sheet 17. When one of the front wheels of the host vehicle 2, for example, the right wheel 8, steps on the protrusion 19, the driver emits the light emitter A 28 located on the center line 17 C of the calibration sheet 17 and the light emitters A 13 located on the vertical sides H on both sides. -Operate and set the first switch 13 and the second switch 14 so that A43 is lit.

When the driving support device 9 sets the vehicle center position 2C and the positions 7C and 8C through which the left and right wheels 7 and 8 pass through the calibration sheet 17, as shown in FIG. When the setting of turning on / off is started (S01), the flag indicating the number (No.) of the light emitter A is set to zero (i = 0, Flg [] = 0) by initialization (S02), and the driver first When the switch 13 is pressed (S03), the light emitter A with the number (No. 1 + i) obtained by adding i to the number 1 is turned on (S04), and the flag Flg [i] = 1 of the light emitter A that has been turned on is set. Is determined (S05).
If this determination (S05) is YES, the driver determines that the illuminant A that has been lit is the illuminant A that corresponds to the center line 17C of the calibration sheet 17, or that the illuminant A that has been lit is the position 7C through which the left wheel 7 passes. It is determined whether the illuminant A corresponds to the illuminant A or the illuminant A that has been lit is the illuminant A corresponding to the position 8C through which the right wheel 8 passes (S06).
On the other hand, if the determination (S05) is NO, the light emitter A with the number i is turned off (S07), and the process proceeds to the determination (S06).
When the determination (S06) is YES and the driver presses the second switch 14 (S08), the lighting of the illuminant A of number 1 + i is confirmed and the flag of the illuminant A that has been lit is set to Flg [1 + i] = 1 is set (S09), i is increased by 1 (i = 1 + i) (S10), and it is determined whether i exceeds the maximum number of the light emitter A (i> Max N0.) (S11).
If the determination (S06) is NO, the i is increased by 1 (i = 1 + i) (S10), and it is determined whether i exceeds the maximum number of the light emitter A (i> Max No.). (S11).
If the determination (S11) is YES, the process proceeds to initialization processing (S02). If the determination (S11) is NO, the process proceeds to a process of pressing the first switch 13 by the driver (S03).

  In this way, the driving support device 9 is set using the calibration sheet 17, so that the driver can easily and quickly reach the vehicle center position 2C in the positions 7C and 8C through which the light emitter A and the left and right wheels 7 and 8 pass. It can set so that the light-emitting body A which corresponds may be turned on.

In the above-described embodiment, the light emitters A are arranged in one row at equal intervals from the left end to the right end of the upper surface of the instrument panel 4, but may be arranged in two or more rows. The driving support device 9 shown in FIG. 7 has a plurality of light emitters A arranged at equal intervals from the left end to the right end of the top surface of the instrument panel 4 and arranged in three rows in the vehicle front-rear direction.
The driving support device 9 in which a plurality of light emitters A are arranged in three rows in the vehicle front-rear direction can indicate the positions 7C and 8C through which the left and right wheels 7 and 8 pass by lighting the three light emitters A connected in a row. Therefore, it is possible to indicate the direction of the passing line.
Therefore, the driving support device 9 makes it easy for the driver to grasp the passing line of the host vehicle 2, and the vehicle center position 2C and the positions 7C and 8C through which the left and right wheels 7 and 8 pass are indicated by arrows 2D, 7D, and 8D. Thus, it is possible to predict far away, the possibility of stepping on the obstacle B at an early stage can be recognized, acts such as a sudden steering operation can be prevented, and the vehicle can move with a margin.
