The motor 144 is an actuator for the pointer to rotate the pointer 143. The motor 144 is located on the surface of a portion of the circuit board 120 on the counter-user side. The portion of the circuit board 120 corresponds to the pointer display portion 140. The motor 144 employs, for example, a stepper motor, which is a synchronous motor operable in synchronization with a pulse power. Rotation of the motor 144 is controlled by using the control unit 160, which will be described later.
The motor 144 includes a shaft 144a extended toward the shaft portion 143a of the pointer 143 and connected with the shaft portion 143a. In the present configuration, the motor 144 rotates the shaft portion 143a, thereby to rotate the needle portion 143b relative to both the display plate 130 and the pointer display portion 140.
The decorating portion 145 is in a cylindrical shape or in a ring shape. The decorating portion 145 is affixed to the surface of the display plate 130 on the user side at the position radially outside both the pointer display portion 140 and the tick mark portion 142.

As to be described later, the control unit 160 is configured to control activation (lighting on) and deactivation (lighting off) of each of the light sources 146a, 146b, 147a, and 147b.
The liquid crystal display portion 150 serves as a display unit to indicate various vehicular information with a digital image. The liquid crystal display portion 150 may be equivalent to an information display portion of the present disclosure. The liquid crystal display portion 150 includes a liquid crystal panel 151, a back light device, and/or the like.
The liquid crystal panel 151 employs, for example, a transmissive liquid crystal panel having a dot-matrix configuration including multiple pixels in a form of a matrix array. The liquid crystal panel 151 is located so that its display surface is viewable through an opening portion 132 of the display plate 130. The liquid crystal panel 151 is configured such that each of the pixels is driven by a control signal sent from the control unit 160 thereby to indicate an image representing various vehicular information. Details of the control unit 160 will be described later.
As shown in
The back light is located on the counter-user side of the liquid crystal panel 151. The back light is configured to perform transmissive illumination of the liquid crystal panel 151 from the backside. The backlight includes a light emitting diode and a diffusion plate and has a configuration to uniformly illuminate the liquid crystal panel 151. The light emitted from the back light enables the liquid crystal panel 151 to perform luminescence indication of the image representing the various vehicular information.
The control unit 160 is configured to acquire various vehicle signals from the various sensors and/or the like equipped to the vehicle and to control the pointer display portion 140 and the liquid crystal display portion 150. In this way, the control unit 160 is configured to cause the pointer display portion 140 and the liquid crystal display portion 150 to indicate the vehicular information corresponding to the acquired vehicle signals. The control unit 160 is configured with, for example, a processor, a program, a flash memory, a RAM, and/or the like. The processor performs various kinds of processings. The program is executed by the processor to perform the processings. The flash memory stores information related to the vehicle and the like. The RAM functions as a work area of the processings.
In addition, the control unit 160 includes a drive circuit and a regulator circuit. The drive circuit is for controlling rotation of the motor 144. The regulator circuit is for controlling luminescence of the light sources 146a, 146b, 147a, and 147b. In addition, the control unit 160 includes a drive circuit and a regulator circuit. The drive circuit is for controlling each pixel of the liquid crystal panel 151. The regulator circuit is for controlling luminescence of the back light.
The transparent display plate 170 is a plate member having a translucency. The transparent display plate 170 is located on the user side relative to the display plate 130. More specifically, the transparent display plate 170 is located on the user side relative to the pointer display portion 140 and the liquid crystal display portion 150. The transparent display plate 170 is affixed to the outer wall 112. The transparent display plate 170 may be equivalent to a display plate of the present disclosure. The transparent display plate 170 is formed with a reflective portion 171. The reflective portion 171 is configured to become luminous in a predetermined shape by the light emitted from the light source unit 180. The details will be described later.
The reflective portion 171 is formed with an aggregate of a large number of recessed portions 171a each being microscopic. The recessed portions 171a are formed on the surface of the transparent display plate 170 on the counter-user side. That is, the recessed portions 171a are formed on the surface of the transparent display plate 170 on the side of the display portions 140 and 150. The aggregate of the recessed portions 171a forms a predetermined shape, such that the aggregate of the recessed portions 171a form, for example, gages at two places. The two places includes, for example, a position, in which the recessed portions 171a overlaps with the tick mark portion 142 of the pointer display portion 140 when viewed from the user side. The two places further includes, for example, a position, in which the recessed portions 171a overlaps with an outer circumferential periphery of the vehicle speed image 151a of the liquid crystal display portion 150 when viewed from the user side. The gauges formed with the aggregate of the recessed portions 171a enables to give the gauge, for example, a further sporty feeling by increasing density feeling than the tick mark portion 142 in the pointer display portion 140.
Each recessed portion 171a among the aggregate of the large number of the recessed portions 171a has a sectional shape such that the recessed portion 171a is in a tapered shape to reduce in its cross section from the counter-user side toward the user side. As shown in
The light source unit 180 is configured to illuminate the reflective portion 171 when being activated (energized). The light source unit 180 is located on the side of a tip end of the transparent display plate 170 in a plate surface direction. In the present example, the light source unit 180 is located underneath the transparent display plate 170. The light source unit 180 includes multiple elements arranged in the left to right direction correspondingly to the entire shape (gauge gauge) of the reflective portion 171. The light source unit 180 employs, for example, light emitting diodes (LEDs) in a red color.
As described above, the reflective portion 171 of the transparent display plate 170 is formed with the microscopic recessed portions 171a. Therefore, the reflective portion 171 is substantially not viewable by the user in a state where the light source unit 180 is not activated and is dimmed. That is, in this state, the transparent display plate 170 is viewed as a transparent board in its original form. To the contrary, when the light source unit 180 is activated and lit to emit light, the light is reflected on the slope of the recessed portion 171a in the triangular shape and is caused to reach the user side. In this way, the transparent display plate 170 renders the gauge viewable by the luminescence of the reflective portion 171.
Further, in the present example, the vehicle is equipped with a driving mode selection switch device, which enables alternative selection of either a normal driving mode, in which moderate driving is enabled, or a sports driving mode, in which fun and quick driving is enabled.
The present meter 100 has the above-described configuration. As follows, operation of the meter 100 will be described with reference to
1. Normal Driving Mode (
The normal driving mode is set when the user selects the normal driving mode by manipulating the driving mode selection switch device.
The control unit 160 activates the light sources 146a and 146b in the pointer display portion 140 thereby to illuminate the digit portion 141 and the tick mark portion 142. In addition, the control unit 160 activates the light source 147a thereby to illuminate the needle portion 143b. Further, the control unit 160 activates the motor 144 to rotate the needle portion 143b according to the rotational speed signal of the engine acquired from the vehicle sensor. The rotational position of the needle portion 143b relative to the tick mark portion 142 and the digit portion 141 represents the engine speed.
In addition, the control unit 160 calculates a vehicle speed value, a shift position, a charge quantity, a remaining fuel quantity, a travelable distance, a trip distance, an average fuel consumption, and a travel distance according to the various vehicle signals acquired from the various sensors for indication of the calculated values on the liquid crystal display portion 150. The control unit 160 processes, as vehicular information, the various images 151a to 151h and causes the liquid crystal panel 151 to indicate the various images 151a to 151h.
In the present normal driving mode, the light source unit 180 is not activated, and thereby the reflective portion 171 of the transparent display plate 170 is not illuminated. Therefore, the indicated contents on the pointer display portion 140 and the liquid crystal display portion 150 are viewed by the user through the transparent display plate 170.
2. Sport Driving Mode (
The sports driving mode is set when a user selects the sports driving mode by manipulating the driving mode selection switch device.
The control unit 160 activates the light source 146a in the pointer display portion 140 thereby to illuminate only the digit portion 141 among the digit portion 141 and the tick mark portion 142. In addition, the control unit 160 activates the light sources 147a and 147b to illuminate the cap portion 143c in addition to the needle portion 143b.
In addition, the control unit 160 calculates the vehicle speed value, the shift position, the charge quantity, the remaining fuel quantity, a water temperature, and an oil temperature according to the various vehicle signals acquired from the various sensors for indication of the calculated values on the liquid crystal display portion 150. The control unit 160 processes, as vehicular information, the various images 151a to 151d and 151i to 151l and causes the liquid crystal panel 151 to indicate the various images 151a to 151d and 151i to 151l.
Furthermore, the control unit 160 activates the light source unit 180. In response, the reflective portion 171 (recessed portion 171a) in the transparent display plate 170 reflects the light to cause the reflected light to reach the user side. In this way, the reflective portion 171 becomes luminous to form the gauge described above. The light source unit 180 employs the LEDs in the red color, and therefore, the reflective portion 171 (gauge) becomes luminous in the red color, which is suitable for sports driving. The gauge formed by the reflective portion 171 is illuminated, when viewed from the user side, at the position of the tick mark portion 142, which is deactivated and dimmed, in the pointer display portion 140 and at the position of the outer circumferential periphery of the digit image 151l of the liquid crystal display portion 150. Therefore, the user views and recognizes the reflective portion 171 superimposed as the gauge on the vehicular information in the pointer display portion 140 and the liquid crystal display portion 150.
Further, the control unit 160 activates the motor 144 to rotate the needle portion 143b according to the rotational speed signal of the engine acquired from the vehicle sensor. The rotational position of the needle portion 143b relative to the reflective portion 171 and the digit portion represents the engine speed.
In addition, the control unit 160 modifies the position of indication of the pointer image 151j relative to the digit image 151i in the liquid crystal panel 151 according to the vehicle speed acquired from the vehicle sensor. In this way, the vehicle speed is indicated according to the rotational position of the pointer image 151j relative to the gauge formed with the digit image 151i and the reflective portion 171. Simultaneously, the vehicle speed is also indicated by the vehicle speed image 151a.
As described above, according to the present embodiment, the transparent display plate 170, which has the reflective portion 171, and the light source unit 180 are equipped on the user side of the pointer display portion 140 and the liquid crystal display portion 150. The transparent display plate 170 has a translucency. Therefore, the present configuration enables the vehicular information indicated by each of the display portions 140 and 150 to be viewable through the transparent display plate 170. In addition, the light source unit 180 is activated to illuminate the reflective portion 171 to form the gauge. The projection reflective portion 171 being illuminated is superimposed on the vehicular information in each of the display portions 140 and 150 and is viewable on the user side. Therefore, the present configuration enables indication to cause the user to feel sense of depth.
In addition, the reflective portion 171 is formed in the surface of the transparent display plate 170 on the side of the display portions 140 and 150. The reflective portion 171 is formed with the recessed portion 171a which is in a taper shape decreasing in width (in size) to the user side. That is, the recessed portion 171a becomes thinner to the user side. The light source unit 180 is located on the end side of the transparent display plate 170 in the plate surface direction.
The present configuration enables to steadily cause the reflective portion 171 to reflect the light emitted from the light source unit 180, which is located on the end side of the transparent display plate 170 in the plate surface direction, to the user side. The plate surface direction is along the main surface of the display plate 170 on which indication is made on the user side. The present configuration need not an installation space for the light source unit 180 in the depth direction.
As shown in
The present configuration further has another group of a transparent display plate 170A, the reflective portion 171A, and a light source unit 180A, in addition to the transparent display plate 170, the reflective portion 171, and the light source unit 180 described in the first embodiment. The transparent display plate 170A, the reflective portion 171A, and the light source unit 180A are located at positions corresponding to the menu image 151m of the liquid crystal display portion 150.
The one group, which includes the transparent display plate 170, the reflective portion 171, and the light source unit 180, and the other group, which includes the transparent display plate 170A, the reflective portion 171A, and the light source unit 180A, are arranged to be directed from the display plate 130 to the user side. The transparent display plate 170 and the transparent display plate 170A are in contact with each other.
The reflective portion 171A formed in the transparent display plate 170A has a configuration (design) different from that of the reflective portion 171 formed in the transparent display plate 170. More specifically, the reflective portion 171A is an aggregate of a number of the recessed portions 171aA The reflective portion 171A is located on each of the right side and the left side of the menu image 151m in
As follows, operation of the present embodiment will be described. The superimposing indication with the reflective portion 171 in the sports driving mode is the same as that of the first embodiment.
In addition, the control unit 160 causes the liquid crystal display portion 150 to indicate the menu image 151m in response to manipulation of the selection switch device, which is equipped to, for example, the steering wheel, by the user. In the present state, the control unit 160 further activates the light source unit 180A to illuminate the reflective portion 171A.
The present embodiment also causes the menu image 151m to enable the user to feel sense of depth by illuminating the reflective portion 171A. In addition, the present configuration enables to switch activation of the light source unit 180 and the light source unit 180A, thereby to enable to switch between the superimposing indication of the gauge in the sports driving mode and the superimposing indication of the ornamental portion of the menu image 151m. In this way, the present configuration enables the user to view the distinct reflective portions 171 and 171A.
The display plate 130 corresponding to the pointer display portion 140 is formed with a character portion 148 and an ECO indicating portion 149 in addition to the digit portion 141 and the tick mark portion 142. The character portion 148 indicates that the vehicle is in an ECO driving state. The ECO indicating portion 149 is formed with, for example, multiple rings for indicating an ECO driving operation level. The ECO indicating portion 149 has a center portion, which emits green light when a predetermined ECO driving condition is satisfied. The ECO indicating portion 149 is further configured to enlarge a green region radially outward from the center portion as the ECO driving level becomes higher. The present configuration further includes light sources for the ECO indication to illuminate the character portion 148 and the ECO indicating portion 149, respectively.
According to the present embodiment, the control unit 160 deactivates the light sources 146a, 146b, 147a, and 147b and activates the light source for the ECO indication in the pointer display portion 140 when determining that the driving state of the user is in the ECO driving state in the normal driving mode. In this way, the control unit 160 switches the indication to the ECO indication thereby to indicate the ECO driving information. The present configuration enables to switch indication of the different vehicular information in the same pointer display portion 140.
In the above embodiments, the reflective portion 171 (recessed portion 171aA), which forms the recessed portion 171a, is exemplified by a configuration in a triangular columnar shape (prism shape). It is noted that, the present disclosure is not limited to the example. The reflective portion 171 (recessed portion 171aA) may be in a conical shape and/or in a polygonal cone shape such as a pyramid shape.
In the embodiments, the pointer display portion 140 is exemplified to indicate the engine speed as the vehicular information. It is noted that, the present disclosure is not limited to the example. The pointer display portion 140 may indicate other vehicular information by using the relationship with various vehicular information indicated on the liquid crystal display portion 150.
As described above, the vehicular display device includes the information display portions 140 and 150 to indicate the vehicular information relevant to the vehicle. The vehicular display device further includes the light source unit 180, the display plate 170, and the reflective portion 171. The display plate 170 is translucent and is located on the viewing side relative to the information display portions 140 and 150. The reflective portion 171 is formed in the display plate 170. The reflective portion 171 is configured to be illuminated by the light from the light source unit 180 in the predetermined shape. The reflective portion 171 being illuminated is overlapped with the vehicular information indicated by the information display portions 140 and 150 and is viewable on the viewing side.
According to the present configuration, the display plate 170 is translucent. Therefore, the original vehicular information indicated by the information display portions 140 and 150 is viewable though the display plate 170. Furthermore, the reflective portion 171 illuminated by the light source unit 180 is superimposed on the vehicular information and is viewed on the viewing side. Therefore, the present configuration enables to add sense of depth to the indication.
