Description

The present invention relates to a system, a program, etc. that displays various operating information of a vehicle having a plurality of power sources.

In the case of a vehicle that runs on a single engine, it is sufficient to provide the user with operational information about that engine, and the operational information provided to the vehicle driver may vary greatly, such as engine power, engine speed, coolant temperature, etc. The number was limited.

However, in recent years, vehicles equipped with a plurality of power sources in their power systems are rapidly becoming popular. A good example is a hybrid vehicle that runs by the cooperation of multiple motors and engines. In such vehicles, the types of operational information generated in the power system are rapidly increasing due to an increase in the number of elements composing the power system and the emergence of new operating modes such as cooperation between the components.

Therefore, in vehicles equipped with multiple power sources in the power system, attempts to provide the vehicle driver with all the operating information generated in the power system end up filling the display area with operating information, making it difficult to see the operating information. This results in a situation where it is difficult to say that operating information is provided. Therefore, it is necessary to carefully examine the operating information that should be provided to the vehicle driver.

Furthermore, if the running state of a hybrid vehicle is divided into starting acceleration, slow acceleration, low-speed cruising, acceleration, sudden acceleration, high-speed cruising, deceleration, and stopping, for example, during slow acceleration, high-speed cruising, and stopping, only the engine is driven; The motor is idle or stopped, and the motor and engine work together during starting acceleration, low-speed cruising, acceleration, and sudden acceleration, and during deceleration, the engine is stopped and the motor is charged.

That is, in a vehicle having a plurality of power sources in its power system, operational information generated in the power system may change frequently. Therefore, the frequency with which users pay attention to the operational information of the power system increases, and there is a need for a display that allows the user to understand the operating state of the power system at a glance.

Therefore, automobile manufacturers have narrowed down the operating information that should be provided to users in vehicles that have a plurality of power sources in their power systems to information that allows them to understand the energy distribution of each power source. Hybrid cars and electric cars are rapidly becoming popular in response to global environmental problems and the depletion of fossil fuels in recent years, and users are increasingly interested in the energy distribution of power sources from the perspective of pursuing fuel efficiency. This is the result of consideration.

To give an example of the display mode, a display panel is placed at a location that is visible from the driver's seat. The display panel displays a background image showing a bird's-eye view of the vehicle's power system. A schematic image of each component of the power system is placed on the background image. Then, arrows are displayed between images that schematically represent each component (see, for example, Patent Document 1 and Patent Document 2).

In this case, the arrows identify the components and provide operational information representing the transfer of energy between them. This display mode is sufficient for understanding energy distribution, and the number of types of operating information to be displayed is small.Furthermore, since the meaning of the operating information is displayed as an image, it is easy to understand along with the operating information. It does not reduce sexuality.

For example, there may be a user's desire to pursue fuel efficiency more deeply. Users who have this desire may be interested in not only the energy distribution of each power source but also the cause of the distribution. For example, in some cases, the deterioration of the battery rather than the driving style may affect the energy distribution of the power source. However, if the operating information is limited by focusing on energy distribution as in the past, it becomes difficult to investigate the causes of such energy distribution. On the other hand, if an attempt is made to provide detailed information on each operating state that allows the exploration of the energy distribution and causes of the distribution, a large amount of operating information will be displayed in a complicated manner, making it difficult to check while driving.

That is, in the past, it was not possible to easily grasp the rapidly increasing amount of operating information in a vehicle having a plurality of power sources in its power system, and to provide completeness in providing the operating information without missing it. This situation is not limited to the pursuit of fuel efficiency, but for users who want to deeply pursue driving performance, for example, both understanding the driving performance and the causes of that driving performance are of interest, so it is difficult to understand the driving performance as before. If the display mode is limited to only the operational information that the user is interested in, the ease of grasping and completeness of the operational information that satisfies the user's interest will not be compatible.

In short, users have priorities for the operational information that they need to grasp, and the frequency with which they wish to grasp the information differs depending on the priority. Conventionally, operational information is classified based on whether it is provided or not. It was not possible to achieve both ease of understanding and completeness of information.

The present invention has been proposed in order to solve the problems of the prior art as described above, and its purpose is to provide more operating information in vehicles without reducing the ease with which users can grasp the information. The goal is to provide systems and programs that can.

(1) In order to achieve the above object, the system of the present invention distributes each operating information regarding at least a part of a vehicle having multiple power sources to a plurality of screens, and one screen of the plurality of screens is displayed on the display means, and the screen displayed on the display means can be switched.

This makes it possible to limit the number of actuation information displayed on one screen, making it easier to understand the actuation information. By switching the screen, other operating information can be viewed, making it possible to provide more operating information easily and reliably than before. For example, if the configuration is such that all the operational information desired by the user is distributed to each screen, all the operational information desired by the user can be provided. Therefore, for example, the integrity of operation information regarding a part of the vehicle, such as the vehicle, its power system, or only the electrical system of the power system, can be ensured. Therefore, it becomes possible to fully satisfy the concerns desired by the vehicle driver.

(2) The plurality of screens may include a first screen that collects operational information that the user desires to understand, and one or more second screens that distribute other operational information. .

As a result, the user basically refers to the first screen to roughly understand the trends of the power system related to the desired viewpoint, and when the user wants to pursue the results of the general understanding in depth, refer to the second screen. This is good because it makes it possible to use the method of doing so.

(3) It is desirable that the first screen display operating information that allows the user to roughly understand the operating state of the entire power system of the vehicle. The user can grasp the desired viewpoint from the overview of the entire power system, and can easily determine which page on the second screen should be further referred to. Note that the user's desired viewpoint may be, for example, the pursuit of fuel efficiency, the pursuit of drivability, the pursuit of maintaining the performance of the vehicle, or the pursuit of extending the life of the vehicle.

(4) The first screen is displayed as a power system screen that provides an overview of the entire power system, and the second screen is prepared for each division in which the power system is divided into a plurality of divisions, and the second screen is provided for each section that belongs to the division. It is preferable to display this as a detailed screen for each part where operation information is displayed.

The power system screen provides an overview of the entire power system, making it easy to understand the overall trend of the power system. On the detailed screen for each part, it is possible to investigate the cause of the trend based on the overall trend of the power system. Therefore, it is possible to achieve both ease of grasping and completeness of operation information while obtaining user convenience.

Here, as the operation information that allows the outline of the operation state to be grasped, it is preferable to use, for example, the input and output of energy to each device. When the power system is a so-called hybrid system, that is, when the power system is mainly composed of an engine, a battery, a front motor, a rear motor, and a generator motor, operation information that allows an overview of the operating state is, for example, , engine power, engine speed, cooling water temperature, battery current, battery capacity, front motor power, rear motor power, motor torque distribution ratio, generated power, etc.

Operating information such as engine power, engine speed, coolant temperature, battery current, battery capacity, front motor power, rear motor power, motor torque distribution ratio, and generated power allows you to understand the distribution of energy generated by multiple power systems. In addition to this, it is also possible to discover, for example, discrepancies between the driving state of the vehicle and the operating information, and provide an opportunity to investigate the cause of energy distribution, for example.

(5) The operating information on the power system screen includes an arrow display indicating the direction of energy input and output to each part, or the direction and magnitude of energy, and the other operating information on the detailed screen for each part includes numerical values or It would be good to have a meter display.

As a result, when the user's desired viewpoint is to investigate the energy distribution of multiple power sources and the causes of the distribution, it is possible to improve the ease of understanding the energy distribution, the completeness of information for pursuing the causes of energy distribution, and the user's convenience. You can improve your sexuality all at once.

That is, on the power system screen, the outline of the power system can be grasped at a glance, and, for example, it is easy to grasp the energy distribution at a glance. It can assist the user in understanding energy distribution, which is a frequent user action while the vehicle is running. On the detailed screen for each part, it is easy to find out what mechanism causes the energy distribution. By separating the power system screen and each part details screen, it is possible to quickly respond to requests depending on whether the user wants to confirm the energy distribution or investigate the cause of the energy distribution. good. Note that the magnitude of energy may be indicated by the thickness or color of the arrow.

(6) The first screen displays a power system of the vehicle or a schematic diagram of the vehicle, and a smaller number of operating information than that displayed on the second screen corresponds to the location of the subject. It is preferable that the second screen is displayed in a plurality of columns in which the operation information and the type name of the operation information are grouped together.

On the first screen, since it is displayed together with a schematic diagram of the vehicle, the amount of information is reduced, for example, to avoid complexity, but it is not necessary to display the name that specifies the type of operation information as a character string. With this configuration, the operation information expressed in the character string together with the name character string does not become difficult to see, and is advantageous for grasping the outline of the operation information. On the other hand, on the second screen, for example, more operation information may be displayed together with a name character string that allows the user to understand the meaning of the operation information, and in this way, it is possible to pursue the completeness of the operation information. By using the first screen and the second screen together, it is possible to further improve the ease and completeness of the operation information and the user's convenience.

Further, the power system screen may be a background screen in which the vehicle is drawn in a wire frame, and operation information may be displayed so as to cover the positions of each device. By using the power system screen as a wire frame background screen, it is possible to give the user a sense of realism. Note that it is preferable to prepare various background screens for the power system screen and respond to the user's selection.

(7) The plurality of screens may include a time-series screen that displays changes in the operating information in chronological order. This is useful when it is necessary to grasp the time-series changes in the operation information in order to investigate the cause of the user's problem. For example, it becomes easy to associate changes in operating information with the user's driving, and it becomes possible to make the user understand the desired energy distribution method and the like. The time-series screen may be a line graph screen, a tabular screen, a moving image screen in which numerical values and bar graphs dynamically change by reducing the time scale, or the like, in which time and operation information are associated.

(8) Preferably, the selection of the operation information by the user is accepted, and the operation information selected by the user is displayed in the margin of the first screen. Thereby, for example, it is possible to always grasp operation information, etc. that the user attaches particular importance to in addition to general understanding, without the need for switching, and it is possible to further satisfy the user's interests.

Further, the selection of the operation information by the user may be accepted, and the operation information selected by the user may be displayed in the margin of one or more of the plurality of screens. In other words, it is better to display the operation information selected by the user in the margin not only on the first screen but also on other screens, so that the operation information desired by the user will not disappear from the screen even if the screen is switched, and the user's Convenience can be improved.

(9) Diagnostic information may be displayed in the margin of the first screen, or a display may be provided to notify the existence of diagnostic information. Further, (11) it is preferable to display diagnostic information in the margin of one or more of the plurality of screens, or to display a display notifying the existence of diagnostic information.

The root of the cause that the user seeks sometimes lies in a malfunction of the vehicle. By displaying the diagnostic information in the margin or displaying a display notifying the existence of the diagnostic information, it is possible to easily inform the user of the root cause of the problem. Particularly in systems that provide information on fuel efficiency and driving performance, the affinity of diagnostic information is high, and the risk of users neglecting vehicle malfunctions is reduced. In particular, on the first screen where emphasis is placed on getting a general understanding of operating information, the clutter on the screen will increase somewhat, but even if this complication is exchanged, the accuracy of the general understanding will improve, so it is good. .

(10) A selection of operation information by the user may be accepted, and the operation information selected by the user may be displayed in the margin of one or more of the plurality of screens. In addition to diagnostic information, information that the user considers important can be easily notified. Note that the margin may be an area with no written items at the edge of the screen, or an area with no written items between individual operation information display areas, but it may be an area where there is no written item at the edge of the screen, but it may be an area where there is no written item at the edge of the screen, but it may be an area where there is no written item at the edge of the screen. In consideration of performance, it is desirable to have an area at the edge of the screen with no written information. In particular, since the operating information and diagnostic information displayed in this margin are often important matters for the user, it is more desirable to display the information on the upper corner of the screen near the driver's seat. However, if there is a large margin between the individual operation information display areas and visibility is not a problem, the information can be displayed in the margin.

The screen may be switched in accordance with the user's tap operation and the tapped screen area. In this system, each operation information is distributed over multiple screens, so the information is not crowded on one screen, and the risk of erroneous tap operations can be reduced.

The functions of the system as described above can also be configured to function as a program for realizing on a computer.

According to the present invention, it is possible to provide more operating information, which has rapidly increased in a vehicle equipped with a plurality of power sources in the power system, without reducing the ease with which the user can grasp the information, and without impairing the user's convenience. , can satisfy the user's interests.

The front refers to the surface facing the rear of the vehicle, or in other words, the surface facing the driver. The back side refers to the side opposite the front side. FIG. 2 is a block diagram showing the internal configuration of the electronic device 1 constituting the system of the present invention.

The electronic device 1 shown in FIG. 1 is, for example, a radar detector, a car navigation system, a car audio system, a vehicle status display device, or the like. The electronic device 1 is mounted on a vehicle such as an ordinary car or a truck, and visually provides information generated inside and outside the vehicle to occupants in the form of figures, numbers, character strings, etc.

This electronic device 1 is installed in an interior panel of a vehicle as an in-dash type, or installed in a vehicle interior space as an on-dash type. The on-dash type electronic device 1 is externally attached via a bracket 3. The electronic device 1 is formed of a thin rectangular case body 2. The electronic device 1 is fixed to a vehicle by attaching a bracket 3 to the lower part of the back side of the case body 2 and pasting the bracket 3 on the dashboard of the vehicle.

A DC jack 17 is arranged at the lower part of the back side of the case body 2. The DC jack 17 is for connecting a cigarette plug cord, and is connected to a cigarette socket of a vehicle via the cigarette plug cord so that power can be supplied. A cord for obtaining power via the fuse box may be connected to the DC jack 17 to supply power to the electronic device 1.

A display 5 is provided on the front surface of the case body 2. The display device 5 is a display means for visually displaying information, and is, for example, a liquid crystal display or an organic EL display. A touch panel 6 is provided on the display 5. The touch panel 6 is an input means that accepts user operations, and detects the touch position on the display 5 using a capacitance method or a pressure-sensitive method.

Further, as shown in FIG. 2, the electronic device 1 includes a connection cable 22 connected to the vehicle. The vehicle-side connector is an outlet for extracting various vehicle operation information output from the vehicle's ECU. This vehicle-side connector is, for example, an OBD-II connector also called a failure diagnosis connector. The connection cable 22 has a connector terminal 23 attached to one end thereof, which is detachable from the OBD-II connector. The other end of the connection cable 22 is provided with a connector terminal 25 for connection to a socket opening 24 provided on the side surface of the case body 2, and is also detachable from the electronic device 1.

Furthermore, this electronic device 1 includes a control section 18 inside the case body 2. The control unit 18 is a computer including a CPU, EEPROM, RAM, nonvolatile memory, I/O, and the like. An execution program is stored in the EEPROM, and is appropriately expanded into the RAM and executed by the CPU to realize the control section 18 having various functions.

This control unit 18 is connected to the display 5, the touch panel 6, and the ECU of the vehicle so that signals can be input and output. An operation signal indicating a touch position is input from the touch panel 6 to the control unit 18 . Digital signals indicating various vehicle operation information are input from the vehicle's ECU to the control unit 18 via the connection cable 22 . On the other hand, the control unit 18 outputs the video signal of the display screen displaying the information to the display 5.

The control unit 18 selects one display screen from a plurality of screen candidates for displaying operation information, and outputs a video signal of the selected display screen to the display 5. The control unit 18 selects the next display screen according to the combination of the current display screen and the operation signal indicating the touch position.

For each screen, the type, number, display format, and arrangement position of the operating information to be displayed are determined. How to determine the type, number, display format, and arrangement position of the operating information depends on each purpose of the screen and the ease of visibility and understanding derived from the purpose.

The control unit 18 selects the operation information to be displayed according to the template on the display screen, converts the selected operation information into a specified display format, or selects a figure that matches the operation information from among the figures that conform to the specified display format. Then, a display screen is generated by arranging the converted operation information or the selected display figure in a prescribed screen area, and the converted operation information or the selected display figure is converted into a video signal and output to the display 5.

The control unit 18 stores three types of screens in its memory, distinguishing each screen based on the type, number, display format, and arrangement position of the operating information. The first screen displays a schematic diagram depicting the main components constituting the vehicle or a part of the vehicle, and displays operational information in the form of graphics within the schematic diagram. This first screen is prepared to allow the user to intuitively and generally grasp the matters of interest from the overview of the entire power system.

For example, the first screen is a power system screen P1 that provides an overview of the entire power system of the vehicle, as shown in FIG. This power system screen P1 is a display example on the power equipment 1 mounted on a vehicle equipped with a plurality of power sources. Note that the power source is a source of kinetic energy necessary for running the vehicle. A vehicle equipped with multiple power sources is, for example, a vehicle that combines two or more motors of the same or different types, two or more engines of the same or different types, or a combination of different power sources such as a hybrid system that uses both an engine and a motor. be.

In the power system screen P1, the type of operation information is energy input/output between components of the power system. The number of operation information is smaller than that on the second screen P2 described later, and it is easy to visually distinguish it from other operation information displayed at the same time. The display format of the operation information is arrow displays A1 to A4, making it easy to understand the contents of the operation information at a glance. The operating information is displayed near the main components that input and output energy, making it easy to understand the subject of the information at a glance. That is, this power system screen P1 allows the user to instantly grasp the energy distribution trend of the vehicle.

Specifically, the power system screen P1 has, on a background image B, images G1 to G6 of each part that imitate the main components that input and output energy. On the background image B, in the vicinity of each part image G1 to G6, there are arrow displays A1 to A4 indicating input and output of energy.

Background image B is made up of a wide plate reminiscent of a vehicle chassis with tire shapes placed at four locations around it. The images G1 to G6 are a front drive shaft image G1, a rear drive shaft image G2, an engine image G3, a battery image G4, a front motor image G5, and a rear motor image G6. The front drive shaft image G1 and the rear drive shaft image G2 are part of the background image B. The engine image G3, battery image G4, front motor image G5, and rear motor image G6 are icons.

Arrow displays A1 to A4 are arrow display A1 indicating that the vehicle is being driven by the energy output of the engine, arrow display A2 indicating that the vehicle is being driven by the energy output of the front motor for driving the vehicle, An arrow display A3 indicates that the vehicle is being driven by the energy output of the rear motor, and an arrow display A4 indicates that the engine is exchanging energy with the battery via the generator motor.

In this power system screen P1, the operation information displayed by arrow displays A1 to A4 indicates the type of information and the content of the information. That is, the display position of the arrow intuitively represents the type of actuation information. The direction of the arrow represents the input/output direction of energy. Further, the thickness or color of the arrow represents the input/output amount of energy. The control unit 18 receives numerical data of operation information to be displayed on the power system screen P1 from the ECU of the vehicle, generates arrow displays A1 to A4 according to the sign and size of the numerical data, and arranges them on the power system screen P1. do.

The second screen displays various operating information representing the detailed operating state of one of the main components constituting the vehicle in numerical form in a tabular format. This second screen is prepared to allow the user to investigate the cause of the vehicle operating condition ascertained on the first screen.

For example, the second screen, as shown in FIG. 4, is a detailed part screen P2 that displays various operating information regarding one main component constituting the power system. Each part details screen P2 displays various operating information of one main component arranged in multiple rows and columns on the screen. The operation information is displayed as a numerical value D1, and the operation information is displayed side by side with a type name character string D2 indicating the type name.

For example, the details screen P2 for each part of the engine includes engine power, engine load, ignition timing, injection time, cooling water temperature, engine oil temperature, accelerator opening, engine speed, engine torque, intake manifold pressure, intake air amount ( Type name character strings D2 indicating MAF), intake air temperature, and battery voltage are arranged in two columns and seven rows, and numerical display D1 of corresponding operation information is arranged with units on the right side of each type name character string D2.

It should be noted that the detailed screen P2 for each part may be configured to display a plurality of components or various types of operation information across a plurality of components. In other words, the manner in which each piece of operating information regarding one main component is displayed is an example of displaying detailed operating information regarding the power system in sections, and each part constituting the power system can be divided into multiple parts from various viewpoints. However, each part detail screen P2 may be prepared for each division, and operation information regarding each part belonging to that division may be displayed.

FIG. 5 is an example of each part details screen P2 based on another classification. The detailed screen P2 for each part shown in FIG. 5 displays operating information for each part of the entire power system in more detail than the display of operating information on the power system screen P1, and adds operating information regarding air conditioner consumption from the electrical system. Specifically, engine oil temperature, system power, front motor power, battery current, battery voltage, auxiliary battery, total battery capacity, engine power, voltage after boosting, accelerator opening, air conditioner consumption, generator power generation, HV glide, and a numerical display D1 of operation information of the number of existing diagnostic codes are arranged, and are paired with a type name character string D2.

The third screen displays one piece of operating information in chronological order. This third screen is used to verify and confirm the probable cause from the perspective of time change on the second screen, which is the detail screen for each part P2, or to obtain confirmation using the first screen, the power system screen P1. It is designed to help discover the causes of certain situations based on changes over time.

For example, the third screen, as shown in FIG. 6, is a time-series screen P3 that shows numerical changes over time of one piece of operation information in a graph. The time series screen P3 has orthogonal coordinates. The operating information is plotted in Cartesian coordinates to form graph D3. In the orthogonal coordinates, the horizontal axis is the passage of time, and the vertical axis is the numerical value of the operation information.

The control unit 18 stores the relationship among the power system screen P1, each part details screen P2, and the time series screen P3 in a three-layer tree structure. The layers are switched and displayed on the display 5 according to the user's operation. In the three-layer tree structure, the power system screen P1 is located at the top layer, which can also be called a top screen, root screen, or home screen. Each part detail screen P2 is located in the middle layer. The time series screen P3 is located at the bottom layer. Then, the control unit 18 associates a plurality of part detail screens P2 with the power system screen P1, and associates a plurality of time series screens P3 with each part detail screen P2.

When an icon represented by each part image G3 to G6 is pressed on the power system screen P1 by a user operation using the touch panel 6, the control unit 18 displays a detailed screen for each part of the component corresponding to the pressed icon. is displayed on the display 5. In addition, when the numerical display D1 of the operation information on the detailed screen P2 of each part or its type name character string D2 is pressed by a user operation using the touch panel 6, the control unit 18 displays the information in the pressed display area. A time series screen P3 of operation information is displayed on the display 5.

FIG. 7 is a table schematically showing a tree structure stored in the control unit 18. As shown in FIG. 7, in response to the depression of the engine image G3 displayed on the power system screen P1 in the uppermost layer, the control unit 18 causes the display 5 to display a detailed screen P2 of each part related to the engine. The details screen P2 for each part related to the engine includes engine power, engine load, ignition timing, injection time, cooling water temperature, engine oil temperature, accelerator opening, engine speed, engine torque, intake manifold pressure, MAF, intake air temperature, and battery voltage. The indicated type name character strings D2 are arranged in two columns and seven rows, and the numerical display D1 of the corresponding operation information is arranged on the right side thereof.

In response to the depression of the battery image G4 displayed on the power system screen P1 on the top layer, the control unit 18 causes the display 5 to display a detailed screen P2 for each part related to the battery. The details screen P2 for each part related to the battery includes a type name character string D2 indicating battery current, battery capacity, battery voltage, voltage after boosting, MAX and MIN of battery block voltage, MAX and MIN of battery temperature, and MAX and MIN of internal resistance. are arranged in seven rows, and the numerical display D1 of the corresponding operation information is arranged on the right side.

In response to pressing down of the front motor image G5 displayed on the power system screen P1 on the top layer, the control unit 18 causes the P2 display 5 to display a detailed screen for each part related to the front motor. On the details screen P2 for each part related to the front motor, type name character strings D2 indicating front motor power, front motor torque, front motor rotation speed, front motor temperature, and front motor inverter temperature are arranged in five rows, and the type name character string D2 indicating the front motor power, front motor torque, front motor rotation speed, front motor temperature, and front motor inverter temperature is arranged in five rows. The numerical display D1 of the corresponding operation information is arranged.

In response to the press of the rear motor image G6 displayed on the power system screen P1 on the top layer, the control unit 18 causes the display 5 to display a screen P2 detailing each part regarding the rear motor. On the details screen P2 for each part related to the rear motor, type name character strings D2 indicating rear motor power, rear motor torque, rear motor rotation speed, rear motor temperature, rear motor inverter temperature, and motor torque distribution ratio are arranged in six rows, and Numerical display D1 of corresponding operation information is arranged next to it.

When an iconized generator motor image is displayed on the power system screen P1 on the top layer, the control unit 18 displays a detailed screen P2 of each part related to the generator motor on the display 5 in response to pressing the generator motor image. let On the details screen P2 for each part related to the generator motor, type name character strings D2 indicating generated power, generator rotation speed, generator torque, generator temperature, and generator inverter temperature are arranged in five rows, and the corresponding operation information is displayed to the right. The numerical display D1 of is arranged.

A usage example for explaining the operation of this electronic device 1 will be explained based on FIG. 8. First, a driver of a vehicle having a plurality of power sources displays the power system screen P1 on the display 5 while driving, and grasps the energy distribution of each power source in the context of the entire power system. When the driver wishes to view operating information not displayed on the power system screen P1 in order to investigate the cause of the energy distribution grasped on the power system screen P1, the driver presses any of the icons displayed on the power system screen P1. do.

For example, when the arrows coming out of the front motor and rear motor on the power system screen P1 indicate an energy output amount that is lower than normal, it is conceivable that the driver presses the icon of the battery image G4. At this time, an operation signal is input from the touch panel 6 to the control unit 18 with the icon of the battery image G4 as the touch position.

In response to this operation signal, the control unit 18 switches the display screen of the display 5 to a detailed screen P2 of each part of the battery. The driver can check the operating information of battery current, battery capacity, battery voltage, voltage after boosting, battery block voltage MAX and MIN, battery temperature MAX and MIN, and internal resistance MAX and MIN displayed on the battery details screen P2. Consider. As a result of the examination, for example, if the battery current is too low, battery deterioration is suspected as the cause of energy distribution. Furthermore, if the internal resistance MAX is excessive, there is a certain certainty that the battery will deteriorate.

Furthermore, the driver may suspect that the battery is initially defective. At this time, the driver presses either the numerical value display D1 indicating operational information such as battery voltage or the type name character string D2 of the numerical value on the battery component details screen P2. For example, press the internal resistance (MAX). The touch panel 6 that has detected this press inputs an operation signal indicating the touch position to the control unit 18.

Upon receiving the input of this operation signal, the control unit 18 causes the display 5 to display a time-series screen P3 of the touched operation information. The driver can observe the graph D3 of operating information such as internal resistance displayed on the time series screen P3 and determine whether the battery is initially defective or has deteriorated over time.

Such an electronic device 1 is an example assuming a case where a user is interested in the fuel efficiency of a vehicle and desires to understand energy distribution and investigate the cause thereof. Operation information that answers other concerns is collected on the first screen while ensuring visibility and understanding, and operation information for investigating other causes is distributed to one or more second screens. You can also. Other concerns include pursuit of drivability, maintenance of vehicle performance, and pursuit of longer life.

As described above, the electronic device 1 constituting the system according to the present embodiment distributes each operation information regarding at least a part of a vehicle having a plurality of power sources to a plurality of screens, and selects one of the plurality of screens. The screen is displayed on the display device 5, and the screen displayed on the display device 5 can be switched.

This makes it possible to limit the number of actuation information displayed on one screen, making it easier to understand the actuation information. By switching the screen, other operating information can be viewed, so that the operating information desired by the user can be provided without missing any information. Therefore, the integrity of operating information regarding a part of the vehicle, its power system, or only the electrical system of the power system can be ensured. Therefore, it becomes possible to fully satisfy the concerns desired by the vehicle driver.

The plurality of screens include a first screen that collects operational information that the user desires to understand, and a second screen that distributes other operational information. That is, for example, if a user is interested in fuel efficiency, the user would like to understand the energy distribution of multiple power sources, so the operation information regarding the energy input and output of the main components constituting the power system is collected on the screen.

As a result, the user basically refers to the first screen to roughly understand the trends of the power system related to the desired viewpoint, and when the user wants to pursue the results of the general understanding in depth, refer to the second screen. This is good because it makes it possible to use the method of doing so.

The first screen displays operating information that allows the user to roughly understand the operating status of the entire power system of the vehicle. The user can grasp the desired viewpoint from the overview of the entire power system, and can easily determine which page on the second screen should be further referred to.

When displaying operating information that allows you to roughly understand the operating status of the entire power system on the first screen, display the first screen as the power system screen P1 that provides an overview of the entire power system, and display the second screen as a power system screen P1 that provides an overview of the entire power system. The screen is prepared for each division, and is displayed as a detailed screen P2 for each part on which operation information regarding each part belonging to the division is displayed.

On the power system screen P1 that provides an overview of the entire power system, it is easy to grasp the overall trend of the power system in a concise manner. On the detailed parts screen P2, it is possible to investigate the cause of the trend based on the overall trend of the power system. Therefore, it is possible to achieve both ease of grasping and completeness of operation information while obtaining user convenience.

As operating information on the power system screen P1, arrow displays A1 to A4 are provided to indicate the direction of energy input and output to each part, or the direction and magnitude of energy, and as other operating information on the detailed screen P2 for each part, numerical display is provided. Equipped with D1. As a result, when the user's desired viewpoint is to investigate the energy distribution of multiple power sources and the causes of the distribution, it is possible to improve the ease of understanding the energy distribution, the completeness of information for pursuing the causes of energy distribution, and the user's convenience. You can improve your sexuality all at once.

That is, on the power system screen P1, the outline of the power system can be grasped at a glance, and, for example, it is easy to grasp the energy distribution at a glance. It can assist the user in understanding energy distribution, which is a frequent user action while the vehicle is running. On the detailed screen P2 of each part, it is easy to find out what mechanism causes the energy distribution. By separating the power system screen P1 and each part details screen P2, it is possible to quickly respond to requests depending on whether the user wants to confirm the energy distribution or investigate the cause of the energy distribution. It's good because it will be. Note that the magnitude of energy may be indicated by the thickness or color of the arrow.

Further, the first screen displays the power system of the vehicle or a schematic diagram of the vehicle, and displays a smaller number of operating information than is displayed on the second screen in correspondence with the location of the subject. , the second screen is displayed in a plurality of columns, with the operation information and the type name of the operation information set as a set.

On the first screen, since it is displayed together with a schematic diagram of the vehicle, the amount of information is reduced to avoid complexity, but it is not necessary to display the name that specifies the type of operation information as a character string. Therefore, the operation information written in the character string together with the name character string does not become difficult to see, which is advantageous for grasping the outline of the operation information. On the other hand, on the second screen, since more operation information is displayed together with name character strings that allow the user to understand the meaning of the operation information, it is possible to pursue the completeness of the operation information. By using the first screen and the second screen together, it is possible to further improve the ease and completeness of the operation information and the user's convenience.

Furthermore, the plurality of screens includes a time series screen P3 that displays changes in operating information in chronological order. This is useful when it is necessary to grasp the time-series changes in the operation information in order to investigate the cause of the user's problem. For example, it becomes easy to associate changes in operating information with the user's driving, and it becomes possible to make the user understand the desired energy distribution method and the like. The time-series screen may be any line graph screen, tabular screen, moving image screen in which numerical values and bar graphs dynamically change by reducing the time scale, etc., as long as time and operation information are associated with each other.

Further, as for the screen switching mode, the screen may be switched in accordance with the user's tap operation and the tapped screen area. In this electronic device 1, since each operation information is distributed over a plurality of screens, information is not crowded on one screen, and the possibility of erroneous tap operations can be reduced. However, it is also possible to switch the screen in response to voice input or gesture input. In the case of voice input, the system may be equipped with a microphone, or a microphone already mounted on the vehicle may be used. In the case of gesture input, the system may be equipped with a camera, or an in-vehicle camera installed in the vehicle may be used. This makes it possible to simplify user operations while the vehicle is running.

An application example will be described assuming that the electronic device 1 is a radar detector. As shown in FIG. 9, the radar detector includes a control unit 18 and a database 19 that can input and output data. The database 19 can be realized by a nonvolatile memory (eg, EEPROM) inside the microcomputer of the control unit 18 or externally attached to the microcomputer. Note that map data and information regarding certain warning targets are registered in the database 19 at the time of shipment, and data regarding warning targets added thereafter are updated as described above.

The remote control receiver 32 performs data communication with a remote control (portable device: child device) 33 using infrared rays, and performs various settings for the device. The infrared communication device 34 sends and receives data to and from a communication device including a built-in infrared communication device, such as a mobile phone 35.

In this radar detector, the control unit 18 has a GPS log function, a standby screen display function, a map display function, a GPS alarm function, a radar wave alarm function, a radio alarm function, and the like. The standby screen display function distributes each operating information regarding at least a part of the vehicle to a plurality of screens, displays one screen of the plurality of screens on a display means, and enables switching of the screen displayed on the display means. It is something to do. That is, this radar detector switches and displays a power system screen, each part details screen, and a time series screen on the display 5 as a standby screen according to the user's operation.

The GPS log function is a function in which the control unit 18 associates the current position detected by the GPS receiver 13 with the detected time and speed (vehicle speed) every second and stores it in a nonvolatile memory as a position history. This position history is recorded, for example, in NMEA format.

The map display function, as shown in FIG. 10, is a function that accesses the database 19 based on the current position detected by the GPS receiver 13, reads out and displays map data stored therein. In addition, the map display function searches for warning targets around the current location based on the location information stored in the database 19, and if there are warning targets around, displays the warning target at the corresponding position on the map. It also has a function to display information (target icon 112, etc.) in an overlapping manner. The specific display mode is as follows.

The control unit 18 displays the map in the main display area R1 on almost the entire surface of the display 5 so that the traveling direction of the vehicle always faces upward. The control unit 18 displays the map so that the lower center of the main display area R1 is the current vehicle position, and displays the vehicle icon 111 at the current position.

The status area R2 is a transparent area and is arranged using a layer above that of the main display area R1. As a result, even within the status area R2, the map located below can be visually recognized at locations where status information is not displayed.

The control unit 18 displays current scale information (reduced scale) in a scale display area R3 set on the left side of the main display area R1. The scale assumes that the own vehicle position is 0 m, and displays the distance from the own vehicle position to the vertically intermediate position of main area R1 ("500" in the figure) and the distance to the upper position ("1000" in the figure) do. The unit is "m". When the control unit 18 detects that the main display area R1 has been touched twice consecutively, it displays a map scale change button at a predetermined position in the main display area R1 (a position along the scale display area R3) (as shown in the figure). (omitted), the map scale is changed according to the touch on the map scale change button. That is, the control unit 18 changes the scale of the map displayed in the main display area R1 according to the changed map scale, and also changes the scale information displayed in the scale display area R3.

During the execution of the standby screen display function and the map display function (hereinafter these functions are collectively referred to as standby functions), the control unit 18 controls the GPS alarm function, radar wave alarm function, and wireless alarm function according to an event that occurs. It executes processing to realize each function such as an alarm function, and returns to the original standby function processing when the processing of the function is completed. The priority of each function is set in the order of radar wave warning function, radio warning function, and GPS warning function from the highest.

The GPS alarm function is a process that is executed at predetermined time intervals (1 second intervals) based on events from a timer included in the control unit 18, and is based on the latitude and longitude of the alarm target stored in the database 19 and the information detected by the GPS receiver 13. The distance between the two is calculated from the latitude and longitude of the current position, and when the calculated distance reaches a predetermined approach distance, a GPS warning display 130 (schematic diagram of the warning target, remaining distance, etc.) is displayed on the display 5. This is a process in which the speaker 16 outputs an approach warning sound to that effect.

These warning targets include drowsy driving accident points, speed measurement devices (radar type, loop coil type, H system, LH system, phototube type, mobile type, etc.), speed limit switching points, enforcement areas, inspection areas, parking monitoring.

Alternatively, photo data and audio data are stored in the database 19 in association with each other.

FIG. 11(a) shows a display example of the radar wave warning function. This radar wave warning function is activated when the microwave receiver 14 detects a signal corresponding to a microwave in a frequency band emitted from a speed measuring device (such as a mobile radar (hereinafter simply referred to as "radar")). This is an alarm function that displays a GPS alarm display 131, which is an alarm screen, on the display 5 and outputs an alarm sound from the speaker 16. For example, when microwaves in the microwave frequency band emitted by a radar are detected by the microwave receiver 14, a schematic diagram or photograph of the radar stored in the database 19 is displayed as shown in FIG. 11(b). At the same time, the sound data stored in the database 19 is read out and a sound saying "Radar. Be careful of speed" is output from the speaker 16. The displayed distance may be, for example, a distance estimated from the electric field strength.

The wireless alarm function is a function that issues an alarm when the wireless receiver 15 receives radio waves emitted by an emergency vehicle or the like so as not to interfere with the vehicle's movement. Radio alarm functions include enforcement radio, car location radio, digital radio, special small radio, police radio, police telephone, police activity radio, towing radio, helicopter radio, fire helicopter radio, fire radio, emergency radio, and highway radio. , scans the frequencies of security radios, etc., and when a radio signal is received at the scanned frequency, a schematic diagram indicating that a radio signal corresponding to the frequency has been received stored in the database 19 for each radio type is displayed as an alarm screen. In addition to displaying the information on the display 5, the audio data stored in the database 19 for each wireless type is read out, and the speaker 16 outputs a warning voice indicating the wireless type. For example, when a police radio signal is received, a voice message such as "This is a police radio signal. Be careful of speed" is output.

(Second embodiment)
