`In Figure 10, a set speed display readout is depicted which displays the cruise travel speed
`which was disclosed in Utility model disclosure publication lP 4-102059.In the same figure, (1)
`is a partial depiction of a combination meter and incorporated in speedometer (2). The set speed
`display readout (3) is formed in which are arranged a dot shaped indicator (5) formed from such
`as light emitting diode (LED) with 5 Km increments in the circumference of the leok-back plate
`of the speedometer (2) scale (2a).
`[0004]

`cruise speed readout is an unnecessary meter during normal driving, and there is the
`disadvantage that the indicator is obtrusive during normal driving in order to have set speed
`display readout around the periphery of the speedometer scale. In addition, in order to have the
`dot-shapes in the periphery of the speedometer scale for the set speed display readout, the
`appearance of the design is not superior, there may be some discomfort with the design, and
`there is room for improvement. Furthermore, there is a burden in that the line of sight must me
`shifted to be able to read the scale of the speedometer in order to confirm the speedometer scale
`during driving and the set speed of the set speed display readout because the set speed display
`readout is present in the periphery of the speedometer scale.
`[0006]

`[0014]
`[Embodiments]
`Embodiments of the vehicle display unit will be explained referring to the drawings including
`the cruise speed indicator ofthe cruise speed device relating to the present invention. Figure 1 (a)
`is a cross-section drawing depicting one embodiment of the present invention.
`In the same drawing, (10) is a case, (11) is a speedometer, (12) is an indicator needle, (13 a) is
`illumination to light the indicator needle (12), (13 b) is illumination to light a scale (14a) of dial
`face (14), (15) is the established speed display panel which displays a set speed established by
`the cruise speed travel unit, (16) is illumination to light a display panel 15, (17) is a half-mirror,
`and (18) is a cover glass. The speedometer (11) is arranged rearward of half-mirror (17) and the
`design of the face dial (14) and the needle (12) is depicted in Figure 2 (a). The dial face (14) is
`formed with a light blocking resin and the like, and the scale is formed with a light transparent
`resin. The indicator needle (12) is formed with a light transparent resin and the illumination (14a
`and 14 b) is installed behind the needle indicator (12) and the scale (14a). Illumination (14a and
`14b) lights when the ignition switch is ON, light transmits to light the indicator needle (12) and
`the scale (14a) formed from light permeable resin, the display design displays by transmitting
`through the half-mirror (17).
`[0015]
`On the one hand, the set speed display panel (15), which displays the vehicle speed established
`by cruise travel device, I installed above he half-mirror (17). When the vehicle speed is
`established with a cruise control device, the established speed is displayed by the illumination
`means (16) of the vehicle established speed control panel (15), the display light is reflected with
`the half-mirror (17), and superimposed on the scale portion of the speedometer (11) dial face
`(14). Another embodiment of the established speed display panel (15) is depicted in Figure 2 (b)
`and (c) as an example of the illumination means (16).Figure 2 (b) depicts the display design of
`the established speed display panel (15) equipped with the scale (15a) emitting the light. This
`

`
`

`

`display design is incident to the viewpoint of the driver reflecting with the half-mirror (17) and
`superimposed on the speedometer (11) scale (l4a). The established speed display panel (1S) of
`
`(4)
`
`JP Disclosure H8-220118
`
`the scale (15p) display design is depicting the condition which indicates the established speed is
`140 Mother display design is designed as flipped from left to right.
`[0016]
`In order for the scale to display the established vehicle speed by the cruise speed travel device,
`scale (l5a) of the established speed display panel, this is arranged in a super imposed position
`corresponding to the speedometer scale (l4a) depicted in Figure (2a). As an example, scale (15a)
`is formed arranging the tips of rectangular light emitting diodes on a printed circuit board.
`Moreover, the light emitting diodes used in the scale (15a) have a display color different than
`those used for the speedometer scale (14a) and using light emitting diodes that emit red or green
`color for the light emitting diode used in scale (15a) is preferable. As depicted in Figure 2 (c),
`forming scale (l5a) by arranging light emitting diode tips without gaps is preferable. The
`established speed display scale (lSa) is formed for instance with 1 Km increments over a range
`from the low 40 Km speed limit through the high speed limit (140 Km to 140 Km). In addition,
`arrangement of scale (l5a) to indicate a range from 0 Km to 140 Km is preferable. Resolution
`can be raised for the indicator of the established speed since forming the scale (lSa) with 1 Km
`increments is possible by arranging the chip shape ofthe light emitting diodes in this manner.
`[0017]
`In this embodiment, during ordinary driving, light transmitting from the indicator needle (12)
`of speedometer (11) and the scale (l4a), and a driver can visually identify the transmitted light of
`the half-mirror (17) as vehicle information. When setting the established speed with the cruise
`travel speed device, the display design of established speed display panel (15) turns on
`illumination or emits light, and the established travel speed display light reflected with the half(cid:173)
`mirror (17) is superimposed on the display of the speedometer. The driver visually identifies this
`superimposed display design as vehicle information. Naturally, a known display method such as
`the zone display method may be the display method as the illumination means, even in such case,
`indicate the manner of zone display superimposition in a location corresponding to scale (14a) of
`the speedometer (11). For instance, arranging in a manner that the zone displays in S Km
`increments and arranging in a manner to zone display in 5 Km increments according to the light
`emitting diodes are also possible.
`[0018]
`An other embodiment of the present innovation is depicted in Figure 1 (b). With the same
`drawing of the embodiment the established speed display panel is installed at the back of the
`half-mirror (17) and the speedometer is installed on the upper side of the half-mirror (l7).The
`embodiment of Figure 1 (a) is arranged differently. Additionally, the dial face (14) ofthe
`speedometer is mirror-reversed in design in to be reflected by the half-mirror (17).
`In this embodiment, during ordinary driving, a driver can visually identify the transmitted light
`of the half-mirror (17) as vehicle information by light transmitting from the indicator needle (12)
`of speedometer (11) and the scale (14a). The display design of the established cruise speed
`device is turned on when established the cruise speed is set with the cruise travel speed device
`and thereby superimposed on the display of speedometer (11) by the established speed display
`light transmitted through the half-mirror (17).The driver visually identifies this superimposed
`display design as vehicle information.

`Next, the operation of the embodiment of the present innovation will be explained. Figure 3
`depicts the circuit schematic diagram controlling the vehicle display read out provided for the
`established speed display read out of the cruise travel speed travel speed device pertaining to of
`the present innovation. In Figure 3, (19) is the throttle actuator controlling the amount of fuel
`supply to maintain a certain vehicle speed, (20), not shown in the figure, possesses the storage
`device (ROM and RAM), and the CPU (central control unit) operates according to the program
`stored in advance. In the input port of this CPU (20) is connected to the ignition SW (21) which
`is the switch for controlling engine start and stop, the speed sensor (22) that generates a pulse
`corresponding to vehicle speed by the number of revolutions of the vehicle engine, the cruise
`travel set SW (23) which performs the ON/OFF of the cruise speed travel, the established speed
`change SW that changes the established speed of the cruise speed travel, brake SW 25 that
`determines brake operation, and temporary cancelling of cruise speed travel, and the resume SW
`to enter cruise speed travel again.
`[0020]
`In the output port of CPU (20) is connected the throttle valve actuator (19) that drives throttle
`valve of the engine and the established speed display indicator (15).
`[0021 ]
`The flow charts of Figures 4 and 5 will be explained referring to the above configuration
`concerning the vehicle display indicator that is controlled by the cruise speed travel unit.
`The engine starts when ignition SW (21) is on and power is applied to CPU (20).The travel speed
`of the vehicle present between the low speed limit and high speed limit determines whether the
`cruise speed travel flag in step S 1 is in the ON mode. Proceed to step S2 when determined the
`cruise travel mode is not set (NO).Proceed to step S3 cruise speed travel setting SW23 is set in
`step S2. In step 3, the CPU (20) calculates and stores vehicle speed data in the storage device
`(RAM) for the vehicle speed at the time when the cruise travel speed unit of the cruise travel
`speed setting SW 23 is ON. Subsequently, the cruise travel speed flag in step S4 turns ON and
`proceeds to step S5, the predetermined scale (15a) formed from the light emitting diode of the
`cruise speed display panel (15) turns on , which is the vehicle data readout stored in the storage
`unit depicted in Figure 2 (b). Naturally, in step Sl when the cruise speed travel flag is in ON
`mode (YES) proceed to the step below step 6.
`[0022]
`The vehicle traveling at the predetermined vehicle speed proceeds to step 7 when in Step 6 it is
`determined whether or not cancel SW (27) is ON, and proceeds to step S9 when OFF (NO).
`In step S7, tum off the scale (15a) according to the light emitting diode corresponding to the
`cruise speed, proceed to step 8 and set the cruise speed travel flag to OFF.
`In step S9, determine whether the resume (SW26) is ON. Namely, determine whether there was
`again a command to perform cruise speed travel. In step S9, proceed to step S10 when YES and
`proceed to step S 12 when NO.

`Proceed to step 11 with the cruise speed travel flag ON in step SlO and scale (15a) turns on
`according to the light emitting diode corresponding to the set speed with the same method
`described above for the vehicle speed at that time. Proceed to step S 13 with the cruise speed
`travel flag ON in step S12. Determine whether the cruise travel speed change SW24 in ON in
`step S13 and proceed to step S14 in the case of YES. Determine the vehicle speed rise or fall in
`step S14 and increment in speed memory in step S15 when the speed rises. Moreover, proceed to
`step S16 when the speed is lowered and decrement the speed memory. Light the scale composed
`of light emitting diodes corresponding to the predetermined vehicle speed data according to the
`vehicle speed data established in the memory unit in step S 1 7.
`[0024]
`Furthermore, the explanation regarding the brake operation in this flowchart is omitted, but
`control similar to that of the cancel SW is performed when the brake is operated equal to or more
`than a predetermined deceleration value. Then, determine whether the vehicle speed is exceeding
`the limit. The control operation is performed once more from step Sl when the limiter is within
`the limit.
`[0025]
`The flow chart of Figure 5, lights the scale, what is called, and omits the explanation of the
`other control steps which are similar to that described above.
`[0026]
`Figure 6 explains with regard to the light control of light emitting elements such as the light
`emitting diodes of the set speed display panel in the vehicle speed indicator equipped in the set
`speed display indicator of the cruise travel speed unit. The illumination for the actual vehicle
`speed display of the speedometer as depicted in Step S 1 and for the dial face are turned on when
`the ignition SW21 is ON. Subsequently, proceed to step S2, the light emitting diodes of the set
`speed display panel tum on according to the command signal from steps S5, S 11, an S 17 as
`depicted in Figures 4 and 5 to turn on light emitting elements, as shown in Step S4, and displays
`the actual speed of the cruise travel speed. Naturally, only the actual vehicle speed display is
`shown on the speedometer according to the light emitting diode tum off command signal.

`Next, another embodiment ofthe present invention will be explained based upon Figures 7
`through 9. The speedometer (11) which displays the actual speed on the upper side of half mirror
`(17) is equipped in Figure 7 and the set speed display indicator needle (30) is provided rearward
`of the half-mirror (17) which is housed in case (10). The display design is inverted since the right
`and left invert according to the half-mirror (17) display design of speedometer (11 ).In normal
`travel mode, the half-mirror (17) reflects the display design of speedometer (11) positioning
`upward of the half-mirror (17) and this reflected light is displayed as vehicle information
`depicting the travel speed. When the vehicle speed is set up by the cruise control unit, the light
`(32) of setting speed display indicator needle (30) is turned on and indicator needle (30) emits
`light, which transmits through half-mirror (17) and is superimposed on the indicator needle (12)
`and scale (14a) of the speedometer (11), resulting in a display design as shown in Figure 9.

`display indicator needle (30) is provided. In the ordinary travel condition, the display design of
`speedometer (11) positioned in the back of half-mirror (17) transmits through half-mirror (17)
`and vehicle information is displayed; when the vehicle speed is set up by the cruise control unit,
`light (32 ) of setting speed display indicator needle (30) turns on and the indicator needle (30)
`emits light(32), which is reflected with half-mirror (17) and is superimposed on the indicator
`needle(12) and scale (14a) ofthe speedometer (11), resulting in a display design as shown in
`Figure 9.

`Naturally, as depicted in Figure 2, a light emitting diode is preferable for the set speed display,
`and other emitting means, for example, by florescent lamp is also clearly preferable. In addition,
`the set speed display may emit light as a cross section surface using optical fiber.

`[Effect( s) of the Invention]
`As discussed above, according to the present invention, a vehicle display readout provided
`with setting speed display readout of cruise control unit is made to either display the setting
`speed in the location of scale of the speedometer or to display the setting speed by instructing the
`scale of the speedometer by the indicator needle; and since the instruction of the speedometer
`and setting speed display are displayed within the same dial face, movement of line of vision to
`confirm the actual vehicle speed and the setting vehicle speed can be minimized, resulting in an
`advantage of increasing safety while driving. Moreover, this superimposes a set speed display
`established with the cruise travel speed unit is superimposed in the display according to the
`speedometer, eliminating complexity of the display design, since the set speed can only be
`displayed at the time the cruise travel speed is set and obtains the advantages of extremely
`excellent appearance and the positive effect on the driving sense. Additionally, provides easy
`identification returning to what Km/h when returned (resume button operation) from cruise travel
`speed he safety of the vehicle display readout is high. Moreover, the set speed display readout is
`superimposed on the dial face of the speedometer in a manner by illuminating the speedometer
`and the set speed display readout using the half-mirror, eliminating the complexity of the display
`design since the vehicle display readout is such as to provide the driver only the necessary
`information, obtains the advantages of extremely excellent appearance and a positive effect on
`the driving sense.
