Description

  The present invention relates to a vehicle display device that is provided at the rear of a vehicle and displays a traveling direction of the vehicle.

  On both the left and right sides of the rear part of the vehicle, there are provided vehicle display devices that display vehicle braking by lighting the lamp, change the direction of the vehicle such as turning left and right, and change lanes to change the driving lane by blinking the lamp. ing. When the direction is changed or the lane is changed, the driver operates the operation lever to display the intention to change the direction or change the lane by blinking a lamp.

  There has been proposed a display device that sequentially blinks a plurality of display lamps as a display for turning a direction or changing lanes (Patent Document 1). In recent years, a display device has been proposed in which light-emitting diodes (LEDs) arranged in a row are turned on (flowed) so as to visually recognize the moving direction of the vehicle. By sequentially flashing the display lamps and causing the display lamps to flow, it is possible to reliably recognize a direction change such as a right or left turn or a lane change, in addition to the display of braking.

  In the conventional display device, the speed of lighting of the plurality of display lamps is set to a speed determined regardless of the traveling speed of the vehicle. For this reason, it is possible to recognize that the direction lamp or the lane change is made by illuminating the indicator lamp to flow, but it is a situation where a right / left turn is made after sudden deceleration from high speed traveling, or sudden change in traveling speed In the current situation, it is impossible to predict the behavior of the preceding vehicle specifically, such as whether the vehicle is turning right or left or changing lanes in the absence of traffic.

  From such a current situation, it is considered to shine the display lamp so as to flow at a flow speed according to the traveling speed of the vehicle. By lighting the display lamp so as to flow at a speed corresponding to the vehicle speed, it is possible to cause the following vehicle to predict the possibility of sudden deceleration. However, the lighting of the indicator lamp is performed at the time of changing direction such as turning left and right and when changing lanes, so whether the lighting situation that changes in speed according to the vehicle speed is the situation of changing direction such as turning right or left, The current situation is that it is not possible to determine whether the lane has changed.

The tail lamp device 3 is provided with a braking lamp 4 that lights up in conjunction with the operation of the brake pedal during braking. A direction indicator lamp 5 that is turned on when an operation lever (described later) is operated at the time of turning or turning the lane or changing the lane is provided.

  As shown in FIG. 2, an operation lever 12 is provided on the side of the steering shaft of the steering wheel 11 (for example, on the right side). The operation lever 12 has a function of performing an operation for displaying an intention to change the direction of the vehicle. That is, by tilting the operation lever 12 counterclockwise (upward) at a tilt angle (predetermined angle) α1, the left turn switch is turned on and the left direction indicator lamp 5 is lit, and the operation lever 12 is turned on. Is tilted clockwise (downward) at a tilt angle α1, the right turn switch is turned on and the right direction indicator lamp 5 is lit. By returning the steering wheel 11 to the original position, the operation lever 12 is returned to the original position and the turn switch is turned off.

  The operation lever 12 has a function of performing an operation for displaying an intention to change the lane of the vehicle (lane change) (lane change operation means). That is, when the operation lever 12 is tilted counterclockwise (upward) at a tilt angle (predetermined angle) α2 smaller than the tilt angle α1, the left change switch is turned on during the operation. The left direction indicator lamp 5 is turned on. Further, when the control lever 12 is tilted counterclockwise (upward) at a tilt angle (predetermined angle) α2 and released immediately, the control lever 12 is automatically returned to the initial position and the left change switch is turned on. The left direction indicator lamp 5 is lit for a predetermined period.

  By tilting the operation lever 12 clockwise (downward) at a tilt angle (predetermined angle) α2, the right change switch is turned on and the right direction indicator lamp 5 is lit during the operation. In addition, when the control lever 12 is tilted clockwise (downward) at a tilt angle (predetermined angle) α2 and immediately released, the control lever 12 automatically returns to the initial position and the right change switch is turned on. The right direction indicator lamp 5 is lit for a predetermined period.

  The direction indicator lamp 5 includes a plurality of lighting lamps 15 (light emitting diodes: LEDs) arranged in parallel in the vehicle width direction. That is, the left and right tail lamp devices 3 are each provided with a plurality of lighting lamps 15 as a lamp group. The plurality of lighting lamps 15 are controlled to be lighted according to instructions from the control device. Further, in a vertical direction that is a direction intersecting with the plurality of lighting lamps 15 (for example, a direction orthogonal to each other), as a second lighting lamp, a plurality of vertical lightings are extended upward from a portion in the direction in which the lighting lamps 15 are juxtaposed. A lamp 16 is juxtaposed.

  The vertical lighting lamp 16 is provided to extend upward from an intermediate position in the direction in which the lighting lamps 15 are juxtaposed (reverse T-shaped), but may be provided to extend downward (T-shaped). Is possible. It is also possible to provide the lamps 15 so as to extend upward from the end portions of the lamps 15 in the juxtaposed direction (L-shaped).

  The plurality of lighting lamps 15 and the plurality of vertical lighting lamps 16 are controlled to be lighted in a predetermined state by a command from the control device 21. That is, as shown in FIG. 3, vehicle speed information and operation lever 12 operation information (turn switch, change switch ON / OFF information) are input to the control device 21, and a plurality of lighting lamps are supplied from the control device 21. A lighting command is output to 15.

  The control device 21 is provided with a lighting control means 22, and the lighting control means 22 sequentially flashes the plurality of lighting lamps 15 from the inside to the outside of the vehicle 1, thereby lighting the plurality of lighting lamps 15 so as to flow left and right. . Further, the plurality of vertical lighting lamps 16 are sequentially blinked from the bottom to the top, and the plurality of vertical lighting lamps 16 are lit so as to flow upward. The control device 21 is provided with a lighting setting means 23 for setting the lighting speed of the lighting lamp 15 and the vertical lighting lamp 16, and is controlled by the lighting setting means 23 so as to be lit at a constant speed.

  The control device 21 is provided with lighting speed setting means 24 to which information on change switches of the operation lever 12 (detection information on operation of the lane change operation means) and vehicle speed information are input. When the operation lever 12 is tilted at the tilt angle α2, the change switch is turned on, and the operation of the operation lever 12 when changing the lane is detected.

  When the operation of the operation lever 12 at the time of changing the lane is detected, only at this time (only when the change switch is turned on), the lighting speed setting means 24 makes the lighting lamp 15 according to the vehicle speed, and The lighting flow speed of the vertical lighting lamp 16 (or only the lighting lamp 15) is set. For example, the flow speed is set so that the lighting flow of the lighting lamp 15 and the vertical lighting lamp 16 (lighting lamp 15) is faster when the vehicle speed is high than when the vehicle speed is low.

  When the operation of the operation lever 12 at the time of lane change is detected, the flow speed is set so that the lighting direction of the lighting lamp 15 in the operation direction and the lighting flow of the vertical lighting lamp 16 (lighting lamp 15) become faster. At this time, the vertically lit lamp 16 in the counter-operation direction is turned on. The vertical lighting lamp 16 in the counter-operation direction is lit so as to flow, but the flow speed is set according to the vehicle speed. In this case, all the vertical lighting lamps 16 can be turned on all at once or can be flashed all at once.

When the operation lever 12 is tilted at the tilt angle α1 and the turn switch is turned on, that is, when the direction is changed such as turning right or left, only the plurality of lighting lamps 15 are related to whether the vehicle speed is high or low. Instead, it is lit to flow to the left or right at a preset speed.
When the operation lever 12 is tilted at the tilt angle α2, for example, when the tilt is operated counterclockwise at the tilt angle α2, the lane is changed to the left lane.

  When changing to the left lane, as shown in FIGS. 4 (a), (b), (c), (d), and (e), the plurality of lighting lamps 15 of the left direction indicator lamp 5 are The lamps are lit in order toward the outside (left side), and the lighting lamp 15 is lit so as to flow from the right to the left in the drawing so that the lamp is lit to flow. At the same time or continuously with the lighting of the lighting lamp 15, the vertical lighting lamps 16 of the left and right direction indicating lamps 5 are lit from the bottom to the top. It is made to light up so that it can flow. The lighting lamp 15 of the right direction indicator lamp 5 is kept off.

  When changing lanes, the vertical lighting lamps 16 of the left and right direction indicator lamps 5 are lit so as to flow from the bottom to the top, so that it is visually recognized that the vehicle travels in the same direction. The distinction between the display of the lane change that can be made and the display at the time of turning direction such as a right or left turn can be made clear.

The flow of the lighting operation of the lighting lamp 15 and the vertical lighting lamp 16 described above will be described with reference to FIG.
When the process starts, the vehicle speed is read in step S1, and it is determined in step S2 whether or not the operation lever 12 is operated in a lane change state. That is, it is determined whether the operation lever 12 is tilted at the tilt angle α2 and the left or right change switch is turned on. If it is determined in step S2 that the control lever 12 is not operated in the lane change state, that is, the left or right change switch is not turned on (turned off), the lane change is not performed. Since this is the situation, in step S3, a normal lighting control can be performed so that the plurality of lighting lamps 15 are lit so as to flow to the left or right at a preset speed.

  If it is determined in step S2 that the operating lever 12 is operated to change the lane, that is, the operating lever 12 is tilted at the tilt angle α2 and the left or right change switch is turned on, the left side Alternatively, since the lane is changed to the right lane, the lighting flow speed of the lighting lamp 15 and the vertical lighting lamp 16 (or only the lighting lamp 15) is set in step S4 according to the vehicle speed. That is, the plurality of lighting lamps 15 and the plurality of vertical lighting lamps 16 are sequentially lit at a flow speed corresponding to the vehicle speed. For example, the lighting flow of the plurality of lighting lamps 15 and the plurality of vertical lighting lamps 16 is increased as the vehicle speed increases based on the vehicle speed.

  If it is determined in step S5 whether or not the operating lever 12 has been returned, that is, whether or not the operating lever 12 has been returned and the change switch has been turned off, and if it has been determined that the change switch has not been turned off, The control of S4 is continued. If it is determined in step S5 that the operation lever 12 has been returned and the change switch has been turned off, the lane change has been completed and the end is reached.

  Accordingly, only when the operation lever 12 is operated to change the lane (only when changing the lane), the lighting lamp 15 and the vertical lighting lamp 16 (or only the lighting lamp 15) are turned on according to the vehicle speed. Speed is set. For this reason, it is possible to recognize at what speed the lane change is being made, for example, to notify the possibility that the lane change will be performed at high speed by increasing the lighting flow during high speed driving Can do.

  The tail lamp device described above can determine the lane change by operating the operation lever 12 at a predetermined angle smaller than the angle at the time of turning right or left. In addition, since the vertical lighting lamp 16 is turned on when the lane is changed, it is possible to clearly distinguish the display from a direction change such as a right or left turn. In addition, there are lamp groups on both sides in the width direction of the vehicle. On the side where the lane is not changed, the vertical lighting lamp 16 is lit and the plurality of lighting lamps 15 are not lit so as to flow. It can be recognized that the vehicle is changing the lane to the opposite side.

  And only when the lane is changed, since the plurality of lighting lamps 15 are lit so as to flow at a flow speed corresponding to the vehicle speed, it becomes possible to notify the behavior of the lane change corresponding to the vehicle speed. .

  In addition, although the light emitting diode (LED) was mentioned as the example as the lighting lamp 15, other lamps, such as a light bulb, can also be used.

  INDUSTRIAL APPLICABILITY The present invention can be used in the industrial field of a vehicle display device that is provided at the rear of a vehicle and displays the traveling direction of the vehicle.
