Description

The present invention relates to a system, a program, or the like that displays each operation information or the like of a vehicle having a plurality of power sources.

In the case of a vehicle running on a single engine, it is sufficient to provide the user with operating information about the engine, and the operating information provided to the vehicle driver is extremely high, such as engine power, engine speed, cooling water temperature, etc. It was a limited number.

However, in recent years, vehicles equipped with a plurality of power sources in the power system are rapidly becoming widespread. For example, a hybrid vehicle that travels by the cooperation of a plurality of motors and engines is a good example. In such vehicles, the types of operation information generated in the power system are dramatically increasing due to the increase in the number of elements constituting the power system and the emergence of a new operation mode of cooperation between the components.

Therefore, in a vehicle equipped with a plurality of power sources in the power system, an attempt to provide the vehicle driver with all the operation information generated in the power system results in filling the display area with the operation information, and the visibility of the operation information. It leads to a situation where it is hard to say that it provides operation information. Therefore, it is required to examine the operation information to be provided to the vehicle driver.

Further, when the running state of the hybrid vehicle is classified into start acceleration, slow acceleration, low speed cruise, acceleration, sudden acceleration, high speed cruise, deceleration and stop, for example, only the engine is driven during slow acceleration, high speed cruise and stop. The motor is idling or stopped, and in start acceleration, low speed cruise, acceleration and sudden acceleration, the motor and engine cooperate, and in deceleration, the engine stops and the motor is charged.

That is, in a vehicle having a plurality of power sources in the power system, the operation information generated in the power system can change frequently. Therefore, the user is required to pay more attention to the operation information of the power system, and to devise a display that can grasp the operation state of the power system at a glance.

Therefore, the automobile manufacturer narrows down the operation information to be provided to the user in the vehicle having a plurality of power sources in the power system to the operation information that can grasp the energy distribution of each power source. Hybrid vehicles and electric vehicles are rapidly becoming widespread in response to recent global environmental problems and fossil fuel depletion, and users are interested in the energy distribution of power sources from the perspective of pursuing fuel efficiency. It is the result of thinking.

To give an example of the display mode, the display panel is arranged in a place visible from the driver's seat. A background image that gives a bird's-eye view of the power system of the vehicle is displayed on the display panel. An image illustrating each component of the power system is arranged on the background image. Then, an arrow is displayed between the images illustrating each component (see, for example, Patent Document 1 and Patent Document 2).

In this case, the arrows identify the components and serve as operational information that represents the transfer of energy between them. This display mode is sufficient for grasping the energy distribution, the number of types of operation information to be displayed is small, and the meaning of the operation information is indicated by an image, so that it is easy to grasp in combination with the operation information. It does not reduce sex.

For example, there may be a user's desire to pursue fuel efficiency more deeply. The user who holds the request may be interested in the energy distribution of each power source as well as the cause of the distribution. For example, the deterioration of the battery, rather than the way of driving, may affect the energy distribution of the power source. However, if the operation information is limited by focusing on the energy allocation as in the conventional case, it becomes difficult to find the cause of such energy allocation. On the other hand, if it is attempted to provide the energy allocation and each operating state in which the cause of the allocation can be investigated in detail, a lot of operating information is displayed in a complicated manner, and it becomes difficult to confirm during traveling.

That is, in the past, in a vehicle having a plurality of power sources in the power system, the ease of grasping the rapidly increasing operation information and the completeness of providing the operation information without lacking it have not been compatible. This situation is not limited to the pursuit of fuel efficiency. For example, for a user who wants to pursue driving performance deeply, both grasping the driving performance and the cause of the driving performance are of concern. If the display mode is limited to the operation information to be performed, the ease of grasping and the completeness of the operation information satisfying the matters of interest are incompatible.

In short, the user has a priority in the operation information to be grasped, and the frequency of requesting the grasp differs according to the priority. It was not possible to achieve both ease of grasping information and completeness.

The present invention has been proposed to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide more operation information in a vehicle without deteriorating the user's comprehension. It is to provide a system and a program that can be used.

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

As a result, the number of operation information displayed on one screen can be limited, and the operation information can be easily grasped. By switching the screen, other operation information can be browsed, so that more operation information can be provided easily and reliably than before. For example, if the operation information requested by the user is completely distributed to each screen, the operation information requested by the user can be provided without lack. Therefore, for example, the integrity of the operation information regarding a part of the vehicle such as the vehicle, its power system, or only the electric system of the power system can be ensured. Therefore, it is possible to sufficiently satisfy the interests requested by the vehicle driver.

(2) The plurality of screens may include a first screen in which operation information desired to be grasped by the user is collected, and one or a plurality of second screens in which other operation information is distributed. ..

As a result, the user basically refers to the first screen to roughly grasp the trend of the power system related to the desired viewpoint, and when he / she wants to pursue the result of the outline grasp deeply, he / she refers to the second screen. It is good because it makes it possible to execute the usage method of.

(3) It is desirable that the first screen displays operating information that allows the operating state of the entire power system of the vehicle to be roughly grasped. The user can grasp the desired viewpoint from the whole power system, and it becomes easy to determine which page of the second screen should be further referred to. The user's desired viewpoint may be, for example, the pursuit of fuel efficiency, the pursuit of drivability, the pursuit of vehicle performance maintenance, or the pursuit of long life.

(4) The first screen is displayed as a power system screen that gives a bird's-eye view of the entire power system, and the second screen is prepared for each division of the power system into a plurality of divisions. It is preferable to display it as a detailed screen of each part where the operation information is displayed.

On the power system screen, which gives a bird's-eye view of the entire power system, it is easy to grasp the overall trend of the power system with a slogan. On the detailed screen of each part, it is possible to investigate the cause of the trend based on the overall trend of the power system. Therefore, it is preferable that the ease of grasping the operation information and the completeness can be compatible with each other while obtaining the convenience of the user.

Here, as the operation information that can grasp the outline of the operation state, for example, it is preferable to input / output energy to each device. When the power system is a so-called hybrid system, that is, when the power system is composed mainly of an engine, a battery, a front motor, a rear motor, and a generator motor, the operation information that can roughly grasp 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.

Operation information such as engine power, engine speed, cooling water temperature, battery current, battery capacity, front motor power, rear motor power, motor torque distribution ratio, generated power, etc. grasps the distribution of energy generated by multiple power systems. Not only is it possible, for example, it is possible to discover a discrepancy between the running state of the vehicle and these operation information, and to provide an opportunity to pursue the cause of energy distribution, for example.

(5) As the operation information of the power system screen, an arrow display indicating the direction of energy input / output to each part or the direction and magnitude of energy is provided, and as the other operation information of the detail screen of each part, a numerical value or a numerical value or It is preferable to have a meter display.

As a result, when the energy allocation of multiple power sources and the pursuit of the cause of the allocation are the user's desired viewpoints, the ease of grasping the energy allocation, the completeness of information for pursuing the cause of the energy allocation, and the convenience of the user. You can improve your sexuality at once.

That is, on the power system screen, the power system vein can be grasped at a glance, and for example, the energy distribution can be easily grasped at a glance. It is possible to assist the user's operation, which is frequently performed while the vehicle is running, to grasp the energy distribution. On the detailed screen of each part, it is easy to find out the cause of the mechanism of the energy distribution. By separating the power system screen and the detail screen of each part, it is possible to quickly respond to the request depending on whether the user wants to confirm the energy distribution or to pursue the cause of the energy distribution. Good. 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 operation information than displayed on the second screen corresponds to the existence position of the main body. The second screen may be displayed in a plurality of columns by combining the operation information and the type name of the operation information.

Since the first screen is displayed together with the schematic diagram of the vehicle, for example, the amount of information is reduced in order to avoid complexity, but it is not necessary to display the name specifying the type of operation information as a character string. With this configuration, the operation information expressed as a character string in combination with this name character string is not difficult to see, which is advantageous for roughly grasping the operation information. On the other hand, on the second screen, for example, it is preferable to display more operation information together with a name character string that can understand the meaning of the operation information, and in this way, the completeness of the operation information can be pursued. By using the first screen and the second screen together, it is preferable that the ease of grasping the operation information, the completeness, and the convenience of the user can be further improved.

Further, the power system screen may be a background screen in which the vehicle is drawn by a wire frame, and operation information may be displayed so as to cover the positions of each device. If the power system screen is used as the background screen of the wire frame, the user can be given a sense of reality. It is advisable to prepare various background screens for the power system screen so that the user can select them.

(7) The plurality of screens may include a time-series screen that displays changes in the operation 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. For example, it becomes easy to associate a change in operation information with a user's driving, and it becomes possible for the user to understand a desired energy allocation method or the like. As the time-series screen, it is preferable to have a configuration in which time and operation information are associated with each other, such as a line graph screen, a tabular screen, and a moving screen in which numerical values and bar graphs are dynamically changed by shortening the time scale.

(8) It is preferable to accept the selection of the operation information by the user and display the operation information selected by the user in the margin on the first screen. As a result, for example, it is possible to constantly grasp the operation information and the like, which the user places particular importance on other than for grasping the outline, without switching, and it is possible to further satisfy the interest of the user.

Further, the user may accept the selection of the operation information, and the operation information selected by the user may be displayed in the margin of one or more of the plurality of screens. That is, it is preferable to display the operation information selected by the user in the margin not only on the first screen but also on other screens, and the operation information desired by the user does not disappear from the screen even if the screens are switched. Convenience can be improved.

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

Sometimes the root cause of what users want to pursue is a vehicle malfunction. By displaying the diagnostic information in the margin or displaying the presence of the diagnostic information, it is possible to easily inform the user of the root of the cause. In particular, in a system that attempts to provide fuel efficiency and drivability, the affinity of diagnostic information is high, and the risk of the user leaving a vehicle defect is reduced. In particular, on the first screen in which the emphasis is on grasping the outline of the operation information, the complexity in the screen will increase a little, but even if the complexity is exchanged, the accuracy of the outline grasp will be improved. ..

(10) The operation information selected 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. The margin may be an area on the edge of the screen where there is no notation, or an area between individual operation information display areas where there is no notation, but visual recognition for other operation information. Considering the nature, it is desirable to have an unmarked area on the edge of the screen. In particular, since the operation information and diagnostic information displayed in this margin are often important to the user, the corner side of the upper side of the screen, which is closer to the driver's seat, is more desirable. However, if the margin existing between the individual operation information display areas is large and there is no problem in visibility, the margin can be displayed.

As a screen switching mode, the screen may be switched according to the tap operation of the user and the tapped screen area. In this system, since each operation information is distributed on a plurality of screens, the information does not get mixed in one screen, and the risk of erroneous tap operation can be reduced.

It is also possible to configure the above-mentioned system functions to function as a program for realizing the computer.

According to the present invention, it is possible to provide more operation information that has rapidly increased in a vehicle having a plurality of power sources in the power system without deteriorating the ease of grasping the user, and without impairing the convenience of the user. , Can satisfy the user's interest.
