JP 2011-073678 A

  However, as the number of vehicle-related information increases to three types and four types, the area of one vehicle-related information in the screen becomes narrower.

  Therefore, the present invention has been made to solve such problems and the like, and provides a control system or the like that allows a driver to accurately recognize vehicle-related information even when the types of vehicle-related information increase. For the purpose.

  In order to solve the above-described problem, a system according to the present invention is a control system that performs control to display (1) vehicle-related information that is information based on vehicle information that fluctuates according to a driver's vehicle operation. A scroll area and a non-scroll area are provided in a screen for displaying vehicle-related information, and control is performed to display the vehicle-related information in each of the scroll area and the non-scroll area. The vehicle-related information that can be scroll-displayed is M types, and scroll display control for simultaneously displaying N types of information among the M types is performed, and M> N => 2.

  By doing in this way, the driver | operator can visually recognize simultaneously the vehicle relevant information displayed on the scroll area | region in a screen, and the vehicle relevant information displayed on a non-scroll area | region. Moreover, there are three or more types of vehicle-related information scroll-displayed in the scroll area, and two or more types can be visually recognized at the same time. Therefore, the vehicle-related information displayed in the non-scroll area can always be confirmed without being scrolled, and the vehicle-related information displayed in the scroll area can be confirmed after waiting for the entire scroll. Therefore, even when the types of vehicle-related information increase, the driver can accurately recognize the vehicle-related information.

  For example, if the vehicle related information that the driver always wants to see is placed in the non-scroll area, and the vehicle related information that the driver does not always want to see is placed in the scroll area, the vehicle related information that the driver always wants to see is placed in the non-scroll area. It can be confirmed by looking at it, and it is not necessary to confirm immediately, but when there is information to be confirmed in various ways, such a large amount of information can be confirmed by looking at the scroll area.

  For example, when M = 6, six types of vehicle-related information can be scroll-displayed, and three types of information can be displayed simultaneously. The screen may be configured as the entire display area or may be configured as part of the display area.

  (2) Whereas the non-scroll area displays the vehicle related information that follows the driver's vehicle operation in real time, the scroll area does not follow the driver's vehicle operation in real time. A configuration that performs control for displaying information is particularly preferable.

  In this way, the driver can always check the vehicle-related information that follows the driver's vehicle operation in real time by looking at the non-scroll area. On the other hand, vehicle-related information that does not follow the driver's vehicle operation in real time can be confirmed after the scroll display in the scroll area. For example, a large number of information that does not follow the driving operation in real time can be displayed by scroll display.

  (3) It is good to perform the control which displays the graphical fluctuation | variation display which followed the driver | operator's vehicle operation based on the said vehicle relevant information in real time in the said non-scroll area | region.

  In this way, since the graphical change display of the vehicle related information is not scrolled, the driver always sees the vehicle related information following the driving operation in real time by the graphic change display in real time at a glance. Easy to confirm. In addition, information that does not follow the driving operation in real time can be confirmed by scroll display when the vehicle is stopped.

  (4) It is good to set it as the structure which performs the display by the numerical value of the vehicle relevant information which followed the driver | operator's vehicle operation relevant to the graphical fluctuation display in real time with the graphical fluctuation display of the said non-scroll area | region.

  By doing this, the graphic display of the vehicle-related information and the numerical display related thereto are not scrolled, so the driver always follows his / her vehicle operation by the numerical display together with the graphic change display in real time. The vehicle-related information can be easily confirmed at a glance, and a large amount of information that is not related to the driving operation in real time can be confirmed by a scroll display when the vehicle is stopped. For example, the numerical value of at least one of the fuel flow rate and the instantaneous fuel consumption may be displayed in the vicinity of the graphic fluctuation display in which the fuel falls.

  (5) In the scroll display control, scroll control and scroll control are alternately performed. When the scroll is stopped, the scroll stop position is displayed so that all of the N types of vehicle-related information are displayed. And it is good to set it as the structure which set the relationship of the magnitude | size of the display area of a scroll area | region and N vehicle relevant information.

  In this way, it is possible to reliably grasp N types of vehicle-related information while scrolling is stopped, and it is possible to grasp a large amount of vehicle-related information through control that performs scrolling.

  (6) The display areas of the N types of vehicle-related information may be the same size. In this way, it is possible to easily perform scroll control such as, for example, scrolling with a certain amount of movement to stop scrolling.

  (7) In the screen, "other information" that is information other than vehicle-related information that is information based on vehicle information that fluctuates depending on the driver's vehicle operation is displayed, and a display area for "other information" It is preferable that the non-scroll area is not narrowed and the scroll area is arranged at a position narrowing. In this way, the driver can confirm “other information” (eg, clock) that is information other than vehicle-related information, which is information based on vehicle information that fluctuates according to the driver's vehicle operation, and can also perform his own driving operation. Since the vehicle related information following the vehicle is displayed in a non-scroll area wider than the scroll area, it is easy to see the vehicle related information following the driving operation.

  (8) It is good to comprise as a program for making a computer implement | achieve the function of the vehicle information display system in any one of (1)-(7).

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where the kind of vehicle relevant information increases, the control system etc. which a driver | operator can recognize vehicle relevant information exactly can be provided.

The pedestal 33 is provided with a spherical concave portion at a predetermined position on the upper surface thereof, and the pedestal 33 is made of a material that can be elastically deformed such as rubber and has an appropriate friction coefficient. The outer diameter of the ball portion and the inner diameter of the recess are set to be approximately equal. As a result, in a state where the ball portion has entered the recess, the outer shape of the ball portion and the inner shape of the recess substantially coincide, and the ball portion can rotate and move in any direction along the spherical surface. And while making both diameters substantially correspond and giving an appropriate friction coefficient to the inner shape of the recess, the ball part can be held at an arbitrary angle and posture. Further, since the pedestal 33 can be elastically deformed, when the case body 1 is urged upward while holding the pedestal 33 from the state shown in FIG. 1, the diameter of the opening of the recessed portion increases and the ball portion is recessed. Can be disengaged from. On the other hand, when the pedestal 33 and the ball part are separated, if the ball part is pressed against the opening of the recess and urged to be pushed toward the pedestal 33 in that state, the opening is caused by the elastic deformation of the recess. The part once expands and the ball part is accommodated in the recess. Thereafter, the shape of the recess is restored to the original by the elastic restoring force of the pedestal 33, and the ball portion is prevented from being easily detached from the recess. Further, one surface of an adhesive member such as an adhesive sheet, a double-sided adhesive tape, or a hook-and-loop fastener is attached to the bottom surface of the pedestal 33, and the other surface of the adhesive member is attached to a predetermined position in the vehicle interior such as a dashboard. Thereby, the base 33 is fixed to the predetermined position in the vehicle interior.

  As shown in FIG. 2, the infrared communication device 7 transmits and receives data to and from a communication device incorporating an infrared communication device such as a mobile phone 12. The adapter jack 9 is a terminal for connecting the memory card reader 13. By connecting the memory card reader 13 to the adapter jack 9, the data stored in the memory card 14 attached to the memory card reader 13 can be taken in, or the contents of the memory of the database 19 and the control unit 18 can be transferred to the memory card. 14 can be written. More specifically, when the data stored in the memory card 14 includes update information such as new target information (position information including longitude and latitude, type information, etc.), the update information is sent to the control unit 18. Is stored (downloaded) in the database 19 built in the radar detector, and the data in the database 19 is updated. The function of the memory card reader 13 may be configured to be built in the main body case 1.

  The database 19 is a nonvolatile memory (for example, EEPROM) in the microcomputer of the control unit 18 or externally attached to the microcomputer. Information about a certain target is registered in the database 19 at the time of shipment, and data and the like about the target added after that can be updated as described above. Data update can also be performed via the infrared communication device 7.

A connection cable 22 connected to the connector is provided, and a connector terminal 23 that can be detachably attached to the OBD2 connector of the vehicle is attached to the tip of the connection cable 22. The OBD2 connector is also referred to as a failure diagnosis connector, and is connected to the ECU of the vehicle to output various vehicle information. Furthermore, in this embodiment, the connector terminal 25 for connecting with the socket port 24 provided in the side surface of the case main body 1 of the radar detector is provided at the other end of the connection cable 22. The connection cable 22 can be attached and detached. Of course, the connection cable 22 may be directly connected to the radar detector.

  Therefore, by connecting the connector terminal 23 attached to the connection cable 22 and the OBD2 connector on the vehicle main body side, the control unit 18 acquires various types of vehicle information every second. The vehicle information includes vehicle speed, engine speed, engine load, throttle opening, fuel consumption, instantaneous fuel consumption, intake air amount (MAF), injection opening time, remaining fuel amount, accelerator opening, turn signal information (left and right) There are blinker operation (ON / OFF), steering wheel rotation steering angle information, and the like.

The GPS log function is a function in which the control unit 18 stores the current position detected by the GPS receiver 8 every second in association with the detected time and speed (vehicle speed) in the nonvolatile memory as a position history. This position history is recorded in the NMEA format, for example.
The standby screen display function is a function for displaying the speed, latitude, longitude, and altitude of the host vehicle detected by the GPS receiver 8 on the display unit 5 as shown in FIG.

  As shown in FIG. 3 (b), the radar scope display function is a position where a target within a predetermined range (for example, within a range of about 1 km) from the current position detected by the GPS receiver 8 is stored in the database 19. This is a function of searching based on information and displaying the relative positional relationship between the vehicle position and the position of the target on the display unit 5. In FIG. 3B, “W” on the left side indicates the west, “E” on the right side indicates the east, and “N” on the upper side indicates the north direction, and the horizontal line connecting “W” and “E” and “N” The icon at the intersection of the vertical line extending downward from "" indicates the vehicle position. Icons having characters such as “L”, “RD”, “P”, and “N” indicate the type and position of the target.

  When pressing of a standby switching button provided on the remote controller 17 is detected during execution of the standby screen display function as shown in FIG. 3A, the radar scope display function is switched to as shown in FIG. Further, when it is detected that the standby switch button provided on the remote controller 17 is pressed during the execution of the radar scope display function, a process for switching to the vehicle related information display function shown in FIG. Further, when pressing of the standby switch button provided on the remote controller 17 is detected during execution of the vehicle related information display function, processing for switching to the standby screen display function is performed.

  The control unit 18 performs a GPS alarm function according to an event that occurs during execution of a standby screen display function, a radar scope display function, and a vehicle related information display function (hereinafter, these functions are collectively referred to as a standby function). Then, a process for realizing each function such as a radar wave alarm function and a radio alarm function is executed, and when the process of the function is completed, the process returns to the process of the original standby function. The priority of each function is set in the order of radar wave warning function, radio alarm function, and GPS alarm function from the highest.

  The GPS alarm function is a process executed at a predetermined time interval (1 second interval) by an event from a timer included in the control unit 18 and detected by the latitude and longitude of the target stored in the database 19 and the GPS receiver 8. When the distance between the current position is obtained from the latitude and longitude of the current position and the obtained distance becomes a predetermined approach distance (for example, within 500 m), a GPS alarm display as shown in FIG. This is a process of outputting an approach warning sound indicating that from the speaker 20.

  Such targets include snoozing driving accident points, radar, speed limit switching points, control areas, inspection areas, parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal ignorance suppression systems, police stations, frequent accidents Area, frequent on-board areas, sudden / continuous curve (highway), branch / merge point (highway), ETC lane advance guidance (highway), service area (highway), parking area (highway), highway Oasis (highway), smart interchange (highway), PA / SA petrol station (highway), tunnel (highway), highway radio reception area (highway), prefectural border notice, roadside station, viewpoint parking, etc. The type information of these targets, the latitude / longitude information indicating the position thereof, and the display on the display unit 5 The formula diagram or photo data and audio data are stored in the database 19 in association with each other.

  The radar wave warning function is used when the microwave receiver 4 detects a signal corresponding to a microwave in a frequency band emitted from a velocity measuring device (mobile radar or the like (hereinafter simply referred to as “radar”)). This is an alarm function for displaying an alarm screen on the display unit 5 and outputting an alarm sound from the speaker 20. For example, when a microwave in a microwave frequency band emitted by a radar is detected by the microwave receiver 4, as shown in FIG. 4, a schematic diagram or a photograph of the radar stored in the database 19 is displayed on the display unit 5. While being displayed as an alarm screen, the voice data stored in the database 19 is read out and a voice “Radar. Speed attention” is output from the speaker 20. During sound output, the alarm lamp 6 is turned on.

  The wireless alarm function is a function for issuing an alarm so that the wireless receiver 15 does not interfere with traveling or the like when a radio wave emitted by an emergency vehicle or the like is received. In the radio alarm function, the control radio, car radio, digital radio, special radio, police radio, police phone, police activity radio, wrecker radio, heli tele radio, fire helicopter radio, fire fight radio, emergency radio, expressway radio , Scan the frequency of the security radio, etc., and when the radio is received at the scanned frequency, a schematic diagram showing that the radio corresponding to the frequency stored in the database 19 for each radio type is received as an alarm screen While displaying on the display part 5, the audio | voice data memorize | stored for every radio | wireless classification in the database 19 are read, and the alarm sound which shows the radio | wireless classification from the speaker 20 is output. For example, when a control radio is received, a voice is output like “control radio. Speed attention”. During sound output, the alarm lamp 6 is turned on.

  In addition to these functions, the radar detector of this embodiment includes a vehicle-related information display function as one of standby functions. This vehicle related information display function will be described with reference to FIGS. The vehicle-related information display function is based on the vehicle information obtained from the vehicle via the OBD2 connector described above, fuel flow rate, fuel used this time, accumulated fuel consumption, instantaneous fuel consumption, average fuel consumption, general road average fuel consumption, expressway average fuel consumption, lifetime This is a function for obtaining vehicle-related information such as fuel consumption and displaying it as shown in FIGS.

  There are several means for obtaining the fuel flow rate. First, when a fuel consumption value is periodically output from the vehicle side, the value is used as it is. On the other hand, when the value of the regular fuel consumption cannot be obtained, it can be calculated by a known method based on either the intake air amount or the injection injection time at a fixed sampling time. For example, injection injection time is used. Although the sampling time is arbitrary, it is 1 second here. The fuel used this time is calculated by integrating the fuel flow from the start of the current engine to the present time. Accumulated fuel consumption is calculated by integrating all [0] fuel flow rates from when this device is installed in the vehicle to the present time.

  First, when the instantaneous fuel consumption is periodically output from the vehicle side, the value is used as it is. If it cannot be obtained, the travel distance is calculated from the speed and travel time of the vehicle at a fixed sampling time, divided by the fuel flow rate, and calculated by giving a correction value. The vehicle speed is obtained from the vehicle diagnostic connector 22 described above, and the time is obtained from a timer provided in the microcomputer of the control unit 18. Alternatively, similar to the above, it may be calculated by giving a predetermined correction value to the output of the air flow meter and the engine speed, and performing various predetermined corrections. The average fuel consumption is calculated by calculating the average fuel consumption in the time from the start of the engine to the present time. This is calculated from the accumulation of instantaneous fuel consumption and travel time. Further, the control unit 18 determines whether the current position acquired by the GPS receiver 8 is on a highway or a general road based on road information (including the correspondence relationship between the position and the road type) stored in the database 19. Accumulation of instantaneous fuel consumption on the general road in the time from the start of the engine to the present and the average road average fuel consumption are calculated from the running time, and the accumulation of instantaneous fuel consumption on the expressway in the time from the start of the engine to the present The average highway fuel efficiency is calculated from the travel time. Lifetime fuel consumption is calculated by accumulating all [0] fuel flow rates from when this device is installed in the vehicle to the present, and dividing this by the distance traveled from the time of installation to the vehicle. . Other known methods can be used for calculating these values.

  As shown in FIGS. 7 to 10, the vehicle-related information display screen displayed on the display unit 5 has three rectangular displays of a first rectangular area 51, a second rectangular area 52, and a third rectangular area 53 in order from the left in the left-right direction. Provide an area. The first rectangular area 51 and the second rectangular area 52 are non-scroll areas, and the third rectangular area 53 is a scroll area. The vertical width (height) of the first rectangular area 51 and the second rectangular area 52 is the same, and the vertical width (height) of the third rectangular area 53 is the same as the first rectangular area 51 and the second rectangular area. Vehicle-related information, which is narrower (smaller) than the vertical width (height) of the region 52, and is information based on vehicle information that fluctuates according to the driver's vehicle operation is displayed above the third rectangular region 53. A time display area 59 for displaying the time of “other information” that is other information is provided. In this area, the time acquired by the control unit 18 from the GPS receiver 8 is displayed.

  The first rectangular area 51 is an area for displaying information on the accumulated fuel consumption. In the uppermost part of this area, characters of “accumulated fuel consumption” indicating what vehicle related information is displayed in the area are displayed. An integrated fuel consumption value display area 51a for displaying the integrated fuel consumption numerically is provided below. The unit of the accumulated fuel consumption value is liters. Furthermore, there is provided an integrated fuel consumption graphical display area 51b, which is a display area for displaying graphic fluctuations of the integrated fuel consumption.

  The second rectangular area 52 is an area for displaying information relating to the fuel flow rate. At the top of this area, the text “fuel flow” indicating what vehicle related information is displayed in the area is displayed. A fuel flow value display area 52a for displaying the fuel flow rate as a numerical value is provided below it. The fuel flow rate value is a value obtained by converting an instantaneous value into milliliter / minute. Furthermore, a fuel flow rate graphic display area 52b, which is a display area for displaying a graphic change of the fuel flow rate, is provided below.

  In the fuel flow rate graphic display area 52b, as shown in FIG. 5, a graduated cylinder symbol 31 as a graphic container symbol and a first scale symbol is arranged. In the upper position in the graduated cylinder design 31, a basket design 32 as a liquid design is arranged. A total of ten tank symbols 33 as second scale symbols of the same shape are arranged in the left position adjacent to the graduated cylinder symbol 31 in two rows in parallel in the vertical direction.

  In the integrated fuel consumption display area 51b, as shown in FIG. 6, a laminated symbol 36 in which a large number of block symbols 35 as the third scale symbols are laminated is arranged.

  The graduated cylinder symbol 31 is a container-shaped symbol with an upper opening, and has a graduation line with a full state of 10. As the fuel is consumed, the liquid in the graduated cylinder pattern 31 increases in the image of fuel, and the moving image changes such that the liquid level rises. Furthermore, when the liquid level reaches the full tank position, the liquid disappears instantaneously and becomes a colored state. A video that repeats this empty to full state is displayed.

  In the present embodiment, the capacity of the graduated cylinder pattern 31, that is, the default fuel consumption corresponding to the fluctuation amount from empty to full is set to 100 ml. This default fuel consumption amount is assumed to be an amount consumed by a vehicle with a predetermined fuel consumption in about 2 minutes with fuel consumption only in an idling state. In normal driving, the fuel consumption is two to three times the fuel consumption in the idling state, so that the liquid level of the liquid moving image of the graduated cylinder pattern 31 reaches the full tank position in about several tens of seconds. This is a variation such that the scale of the graduated cylinder symbol 31 increases in real time when the driver visually observes it.

At the stage where the engine has not yet started, the control unit 18 displays the color state on the graduated cylinder pattern 31 as an initial screen. Then, the liquid moving image in which the liquid level rises by the amount of increase corresponding to the fuel consumption is changed. The control unit 18 performs control so as to raise the liquid level in an amount corresponding to the acquired fuel flow rate Bp acquired at a timing of every second that the driver feels in real time. Specifically, if the reference fuel flow rate is Bp1, and the liquid level height data (for example, 30 mm on the screen) when the liquid level of the graduated cylinder pattern 31 is full is N1, the control unit 18 is 1 by this Bp1. The rising amount H1 of the liquid level raised every second can be expressed by the following equation.
H1 = (N1 · Bp1) / 100

  In other words, when the acquired fuel flow rate Bp is 0, for example, before the cell motor is driven and the key is located at the ACC power-on position, the graduated cylinder pattern 31 remains in the empty state. . However, once the cell motor is driven and at least in the idling state, the acquired fuel flow rate Bp can be acquired. Therefore, the control unit 18 changes the moving image such that the liquid level rises according to the above formula.

  Then, when the liquid level reaches the upper end of the graduated cylinder pattern 31, the control unit 18 changes the liquid moving image to disappear and return to the initial screen of the color. Further, the control unit 18 once clears the display of the graduated cylinder symbol 31 with the stop of the engine, and starts the variation again from the initial screen of the color at the next engine start.

  In this embodiment, the rising liquid moving image is displayed in red as a caution color for arousing suppression of fuel consumption. However, the color is not particularly limited to red as long as it is a conspicuous color with respect to the background.

  Next, the kite pattern 32 will be described. The control unit 18 does not display the saddle pattern 32 on the display unit 5 at the stage where the engine has not yet been started, but displays it along with fuel consumption.

  The kite design 32 is a bar-shaped external design that appears at different timings from above the graduated cylinder design 31, and the control unit 18 keeps the kite design 32 at a predetermined position in a random position in the width direction of the graduated cylinder design 31. Then, it is lowered (flowed down) and changed so as to collide with the bottom surface or the liquid surface of the graduated cylinder pattern 31 and disappear. As the liquid level of the graduated cylinder design 31 rises, the descending distance gradually decreases, and the moving surface becomes a movie that is integrated with the liquid level almost simultaneously with the appearance near the upper end of the graduated cylinder design 31.

  In the present embodiment, the control unit 18 causes the number of saddle patterns 32 corresponding to the acquired fuel flow rate Bp to appear from a random position in the width direction every second that the driver feels in real time. In the present embodiment, the soot design 32 is set to be applied according to a table storing the correspondence between the fuel flow rate and the number of soot. This table is set so that the number of soot increases as the fuel flow rate increases. In addition, the number of hail patterns 32 that appear in accordance with the acquired fuel flow rate Bp is changed as appropriate. For example, when the fuel flow rate is about 30 as shown in FIG. 10, the number is 1 or 2, but when the fuel flow rate exceeds 100, 4 or 5 is displayed as shown in FIG. The correspondence relationship between the obtained fuel flow rate Bp and the number of soot is set in advance. In this embodiment, the bag 32 is displayed in red as a caution color for stimulating the suppression of fuel consumption, and in order to coordinate with the liquid animation of the graduated cylinder 31. It is not limited to red.

  Next, the tank symbol 33 will be described with reference to FIG. The tank symbol 33 has a larger scale unit than the graduated cylinder symbol 31, and, like the graduated cylinder symbol 31, in the tank symbol 33, the liquid imaged as fuel increases and the moving image fluctuates such that the liquid level rises. Since the variation of the tank symbol 33 is linked to the variation of the graduated cylinder symbol 31, the control unit 18 returns the liquid level of the graduated cylinder symbol 31 to the full tank position and returns to the initial screen of the color. A liquid moving image in which the liquid level rises in a unit corresponding to an amount of 100 ml is displayed on the tank symbol 33.

  The change display of the tank symbol 33 is executed as follows. As the fuel is consumed, the control unit 18 causes the tank design 33 to change so that the liquid that imagines the fuel rises in order from the lower right side (the graduated cylinder design 31 side) of the two tank designs 33 arranged side by side. Then, when the lower tank symbol 33 becomes full, such as the left tank symbol 33 → the right upper tank symbol 33, the upper tank symbol 33 is changed in order.

The capacity (fuel consumption corresponding to the fluctuation amount) of one tank symbol 33 in the present embodiment is set to 5 liters (L) by default. Therefore, for any tank symbol 33, 5L = 5000ml and 5000 ÷ 100 = 50, and the liquid level rises 50 times in response to the vertical movement of the graduated cylinder symbol 50, so that the tank symbol 33 is just full. It becomes a state. That is, the amount of increase H2 of the liquid level of the tank symbol 33 that is raised each time the control unit 18 returns the graduated cylinder symbol 31 to the initial state can be expressed by the following equation where the height of the tank symbol 33 is N2. .
H2 = N2 / 50

  In this embodiment, since there are ten tank symbols 33 that can store up to 5L, it is possible to express 50L of fuel consumption. Further, the control unit 18 once clears the display of all the tank symbols 33 as the engine is stopped, and starts the variation again from the initial screen of the rightmost lowermost color at the next engine start.

  Next, the laminated symbol 36 and the block symbol 35 will be described. The stacked symbol 36 is an aggregate of small rectangular block symbols 35 of 20 vertical and 10 horizontal, and has a larger scale unit than the tank symbol 33. Although the block symbol 35 is a small shape, it is a variation symbol that fluctuates in the same manner as the tank symbol 33 such that the liquid that imagines fuel rises. One block symbol 35 indicates an amount corresponding to 50L. Therefore, it is possible to express a fuel consumption of 10,000 L. A numerical value indicating the integrated value is also written every 2000L.

  The control unit 18 varies the stacked symbol 36 (block symbol 35) in accordance with the past accumulated fuel consumption amount Pcc. The control unit 18 causes the stacking symbol 36 (block symbol 35) to display the accumulated fuel consumption amount Pcc obtained by adding the fuel consumption from the most recent engine start to the present. Here, the block symbol 35 indicates an amount corresponding to 50 L, but in the present embodiment, the liquid image is displayed in five stages in units of 10 L, and in that case, the unit of 10 L or less is discarded. For example, it is assumed that the integrated fuel consumption amount Pcc is 722L. In that case, 722 ÷ 50 = 14... That is, the 14 block symbols 35 are displayed as full tanks, and the 15th is displayed for 22 L at the half edge. At this time, 2L is discarded and only the liquid level corresponding to 20L is displayed. That is, the liquid image is displayed so that the liquid level is at a position 2/5 from the bottom of the height of the block symbol 35.

  The order of display, that is, the order of use of the block symbols 35 is to display a full tank from the lower left block symbol 35 to the right, and when the column is used up, it moves to the upper stage and again from the left block symbol 35 to the right. I will display the change toward the direction. In the present embodiment, the liquid image is displayed in red as a caution color for stimulating the suppression of fuel consumption. However, the liquid image is not particularly limited to red as long as it is a conspicuous color with respect to the background.

  Next, returning to FIG. 7, the third rectangular area 53 will be described. In the third rectangular area 53, six types of vehicle-related information such as average fuel efficiency, general road average fuel efficiency, expressway average fuel efficiency, lifetime fuel efficiency, fuel used this time, and instantaneous fuel efficiency are arranged one by one in this order in the vertical direction (vertical direction). It arranges, and this arrangement area is scroll-displayed, and among the six types, three types of vehicle related information can be displayed simultaneously. For example, the state of FIG. 7A is a state in which three types of vehicle-related information are displayed: average fuel consumption, general road average fuel consumption, and expressway average fuel consumption. In this state, the operation is stopped for 6 seconds, and the arrangement area is scrolled upward at a constant speed as shown in the middle of FIG. 7B and FIG. 7C, and the following three types are provided as shown in FIG. In the state where the vehicle related information is displayed, the process of stopping for 6 seconds is repeated. The scrolling time is 3 seconds. In this way, the three types are displayed for 6 seconds in a completely displayed state, and scroll display is performed for 3 seconds to display the next one type. The display areas of the six types of vehicle-related information in the arrangement area have the same size, and the space between each piece of vehicle-related information is in the left-right direction orthogonal to the arrangement direction (vertical direction) of each vehicle-related information. Display a separator line. Each vehicle related information display area displays a title character indicating what vehicle related information is displayed in the area. Below that, the value of each vehicle related information is displayed numerically. The unit of average fuel consumption, general road average fuel consumption, expressway average fuel consumption, lifetime fuel consumption, and instantaneous fuel consumption is km / l, and the unit of fuel used this time is liters.

  By scrolling from the state of FIG. 7 (a) to the state of FIG. 7 (d) through the states of FIG. 7 (b) and FIG. 7 (c) over 3 seconds, the average fuel consumption of FIG. From the state in which three types of vehicle-related information, general road average fuel economy and expressway average fuel economy are displayed, the average fuel economy at the top level is scrolled out, and the top level is average road average fuel efficiency and the middle level is expressway It becomes the average fuel consumption, and the lifetime fuel consumption is newly displayed at the bottom. In this state, the vehicle stops for 6 seconds, and similarly scrolls over 3 seconds (not shown). As shown in FIG. 8A, the average road average fuel consumption, the expressway average fuel consumption, and the lifetime fuel consumption shown in FIG. From the state where the three types of vehicle related information are displayed, the average fuel economy of the uppermost road is scrolled out and disappears. The fuel consumption used this time will be displayed. Thereafter, scrolling and stopping are repeated in the same manner. The scroll display is performed so that the stop state appears in the order of FIGS. 8B, 8C, 9A, 9B, and 9C. Do. The vehicle-related information display state in FIG. 9B displays three types of vehicle-related information: average fuel consumption, general road average fuel consumption, and expressway average fuel consumption, as in the vehicle-related information display state in FIG. It shows the state that has returned to the state that was made.

  As shown in FIGS. 7 to 10, the accumulated fuel consumption and the fuel flow rate are always displayed, and the average fuel consumption, general road average fuel consumption, expressway average fuel consumption, lifetime fuel consumption, currently used fuel, and instantaneous fuel consumption are scroll-displayed.

  As described above, the radar detector performs control for displaying vehicle-related information that is information based on vehicle information that fluctuates according to the driver's vehicle operation, and is included in the screen (display unit 5) that displays the vehicle-related information. , A third rectangular area 53 which is a scroll area and a second rectangular area 52 which is a non-scroll area are provided, and vehicle-related information (fuel flow rate, currently used fuel, accumulated consumption) is provided in each of the scroll area and the non-scroll area. Controls to display fuel, instantaneous fuel efficiency, average fuel efficiency, general road average fuel efficiency, expressway average fuel efficiency, lifetime fuel efficiency), and scroll-related vehicle-related information (average fuel efficiency, general road average fuel efficiency, high speed) Scroll display control that displays three types of information at the same time as six types of road average fuel consumption, lifetime fuel consumption, fuel used this time, and instantaneous fuel consumption) It was constructed.

  By doing so, the driver can display several types of average fuel consumption, general road average fuel consumption, expressway average fuel consumption, lifetime fuel consumption, fuel used this time, and instantaneous fuel consumption displayed in the scroll area on the screen and the non-scrolling area. The fuel flow rate displayed on the screen can be viewed at the same time. In addition, there are six types of vehicle-related information scroll-displayed in the scroll area. Of these, three types of information can be viewed at the same time when scrolling is stopped, and one to three types of information can be viewed simultaneously even when scrolling. Therefore, the fuel flow rate displayed in the non-scroll area can always be checked without being scrolled, and the average fuel consumption, general road average fuel efficiency, expressway average fuel efficiency, lifetime fuel consumption, current fuel consumption, instantaneous fuel efficiency displayed in the scroll area All the vehicle related information can be confirmed after waiting for the entire scroll (FIG. 7 (a) to FIG. 9 (a)). Therefore, even when the types of vehicle-related information increase in this way, the driver can accurately recognize the vehicle-related information. In particular, the fuel flow that the driver always wants to see is placed in the non-scroll area, and the average fuel economy, general road average fuel economy, highway average fuel economy, lifetime fuel economy, and fuel used this time that you do not always need to see are arranged in the scroll area. The fuel flow that the driver always wants to see can be confirmed by looking at the non-scrolling area, and it is not necessary to confirm it immediately, but it is the information that you want to check variously, such as average fuel consumption, general road average fuel consumption, expressway average fuel consumption Many information such as lifetime fuel consumption, fuel used this time, and instantaneous fuel consumption can be confirmed by looking at the scroll area.

  The non-scroll area displays fuel flow, which is vehicle-related information that follows the driver's vehicle operation in real time, whereas the scroll area displays average fuel consumption that does not follow the driver's vehicle operation in real time, general roads It is particularly preferable to display the average fuel consumption, expressway average fuel consumption, lifetime fuel consumption, and fuel used this time. In the above-described embodiment, the instantaneous fuel consumption is included in the scroll area. However, it is more preferable that the instantaneous fuel consumption is included in the non-scroll area such as the time display area 59.

  In this way, the driver can always check the vehicle-related information that follows the driver's vehicle operation in real time by looking at the non-scroll area. On the other hand, vehicle-related information such as average fuel consumption that does not follow the vehicle operation of the driver in real time, general road average fuel consumption, expressway average fuel consumption, lifetime fuel consumption, and fuel used this time can be confirmed after the scroll display in the scroll area.

In addition, you may display graphically in a scroll area | region. For example, the display content of the first rectangular area 51 may be displayed as one of a plurality of types of information displayed in the third rectangular area 53. In this case, the vertical length of the third rectangular area 53 is preferably the same as that of the first rectangular area 51 (the time display area 59 is eliminated).
In the present embodiment, control is performed in the second rectangular region 52, which is a non-scrolling region, to display a graphical change display (display of a liquid moving image, etc.) of the fuel flow rate following the driver's vehicle operation based on vehicle information in real time. It was.

  In this way, the graphical change display (second rectangular area 52) of the vehicle-related information is not scrolled, so the driver always follows his driving operation in real time by the graphic change display in real time. The fuel flow rate can be easily confirmed at a glance. In addition, information that does not follow the driving operation in real time can be confirmed by scroll display when the vehicle is stopped.

  Further, the fuel flow value display area 52a is displayed with the numerical value of the fuel flow rate following the driver's vehicle operation related to the graphic change display in real time as well as the graphic change display of the non-scroll area. By doing so, the graphic change display of the fuel flow rate and the numerical display related thereto are not scrolled, so the driver always follows the vehicle operation of his / her vehicle by the numerical display and the numerical change display in real time. The related information can be easily confirmed at a glance, and a lot of information that is not related to the driving operation in real time can be confirmed by a scroll display when the vehicle is stopped. For example, the numerical value of at least one of the fuel flow rate and the instantaneous fuel consumption may be displayed in the vicinity of the graphic fluctuation display in which the fuel falls.

  In the scroll display control of the control unit 18, the scroll control and the scroll stop control are alternately performed. When the scroll is stopped, the scroll stop position is set so that the entire three types of vehicle-related information are displayed. The relationship between the size of the scroll area and the three vehicle-related information display areas is the same for the six types of vehicle-related information display areas in the arrangement area. That is, the vertical width of each vehicle-related information is the same, and the width of about three times the width is set as the vertical width of the third rectangular area 53a, and scrolling is performed in this vertical direction. Since it did in this way, while scrolling has stopped, while being able to grasp | ascertain reliably three types of vehicle relevant information, six types of vehicle relevant information can be grasped | ascertained by the control which performs scrolling.

  In the vehicle related information display screen, the time is displayed in the time display area 59 as “other information” that is information other than the vehicle related information that is information based on the vehicle information that fluctuates depending on the driver's vehicle operation. The “information” display area is arranged so as not to narrow the second rectangular area 52 which is a non-scroll area, but to a position where the third rectangular area 53 which is a scroll area is narrowed. Therefore, the driver can confirm the time that is "other information" that is information other than the vehicle related information that is information based on the vehicle information that fluctuates according to the driver's vehicle operation, and the fuel flow rate that follows her own driving operation is Since it is displayed in the second rectangular area 52 that is a non-scroll area wider than the third rectangular area 53 that is the scroll area, it is easy to see the fuel flow rate that is vehicle-related information following the driving operation.

  As described above, according to the present radar detector, the driver can accurately recognize the vehicle-related information even when the types of vehicle-related information are increased.

  In this embodiment, the display unit 5 and the speaker 20 are provided in the radar detector. However, the radar detector is not provided in the radar detector, and instead includes, for example, a general-purpose device (for example, a monitor, a speaker, or the like). A signal may be output to a mobile phone or the like.

  In the present embodiment, the power supply can be received by connecting to the cigar socket of the vehicle via the cigar plug cord, but the power supply may be received from the OBD2 connector.
