Description

  The present invention relates to a battery state notifying system and a battery state notifying method for notifying a state of a battery mounted on a vehicle.

Since the in-vehicle device is operated by the power supplied from the battery, a technology has been proposed to notify the user of a decrease in the remaining battery level so as to prompt the user to charge or switch off the in-vehicle device before the remaining battery level drops below a predetermined level. (For example, refer to Patent Documents 1 and 2.) The battery remaining amount notification device of Patent Literature 1 outputs a sound effect every time the remaining amount of the battery decreases by a predetermined amount, and notifies by voice when the state is reduced to a state where charging is necessary. Further, the charging status notification system of Patent Document 2 determines whether or not the vehicle can be driven based on the remaining battery level. If it is determined that the vehicle cannot be driven, the driver is notified by blinking a room lamp faster than usual, for example. To do. In addition, a technique has been proposed in which the driver is informed that the remaining battery level is low through an operation performed by the driver when boarding (see, for example, Patent Document 3). In Patent Document 3, a failure to start intentionally when the voltage drops to a voltage higher than the microcomputer operation limit at the time of engine startup by utilizing the fact that the voltage at the time of engine startup drops to a smaller value as the remaining battery level decreases or deteriorates. After the first failure, the engine is allowed to start up to a voltage lower than the first time. If the number of opportunities for starting this pattern increases, the driver can feel that the battery has deteriorated soon.

  However, as in the technology described in Patent Document 1 or 2, there is no sense of urgency just by notifying that the remaining battery level is low due to the sound or blinking of the room lamp, and the driver immediately takes measures such as charging. Not enough to try. This is also predicted from the fact that a vehicle running out of gas despite the presence of a fuel gauge on the meter panel, and even if the battery level is low, the battery level is reduced to a state where it is difficult to start the engine. There is a risk of letting you. In addition, since the first engine start fails, the technology described in Patent Document 3 may give rise to anxiety that the engine may not be able to start beyond the sensation that the battery has deteriorated. There is.

  It is possible to provide a battery state notification system and a battery state notification method that can notify a decrease in the remaining battery level or a deterioration of the battery without feeling uneasy.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows an example of a configuration diagram of a battery state notification system 30. When the remaining battery level is monitored by monitoring the remaining battery level, the battery status notification system 30 of the present embodiment causes the electrical component 20 to imitate a malfunction caused by a shortage of the remaining power level, and allows the driver to decrease the remaining battery level. Inform. When the battery level is actually not enough, the driver can feel the malfunction caused by the electrical component 20 and thus can directly recognize the decrease in the battery level. Moreover, it is possible to prevent the driver from feeling uneasy by limiting the electrical component 20 that mimics the malfunction to the electrical component 20 that is not closely related to driving.

  The battery status notification system 30 is controlled so that, for example, the engine ECU 3 monitors the remaining battery level and sends a mimic command to an electrical component 20 such as an AV (Audio Visual) device 4 when the remaining battery level is below a predetermined level. The Each ECU such as the engine ECU 3 is a CPU for executing a program, a ROM for storing the program, a RAM for temporarily storing data and programs, an EEPROM (Electronically Erasable and Programmable Read Only Memory), and an input / output for inputting and outputting data. An interface and a communication unit that communicates with other ECUs are configured as a microcomputer connected via a bus. When the CPU executes the program, the battery capacity determination unit 3a and the mimicry control unit 3b are realized.

  A battery monitor 2 is connected to the engine ECU 3 as a sensor for detecting the remaining battery level. The battery monitor 2 detects the current value flowing through the battery 1 during charging or discharging and the temperature of the battery 1 and outputs the detected value to the engine ECU 3. The battery capacity determination means 3a of the engine ECU 3 adds a correction value such as the battery temperature to the current at the time of charging / discharging to calculate the remaining amount of the battery and the decrease amount of the battery 1, and when the battery 1 is decreased by a predetermined amount or When the amount is less than the predetermined amount, the mimic control means 3b sends a mimic command to the electrical component 20.

  The electrical component 20 includes, for example, an AV device 4 that reproduces music and video (hereinafter simply referred to as an AV source), an audio signal amplifier 8 provided integrally with the AV device 4, a display device 9 such as a liquid crystal controlled by the navigation ECU 5, Illumination of a room lamp 10 and a switch (SW) lamp 11 in the vehicle controlled by the body ECU 6, an indicator lamp 12 of a combination panel controlled by the meter ECU 7, and the like. These electrical components 20 are facilities that take into account the preference and convenience of the driver who is not in close contact with the driving and driving of the vehicle, such as the engine, drive system, steering system, and brake system, or that does not hinder direct driving It is. For this reason, the driver does not feel anxiety even when mimicking the malfunction, or at least there is less anxiety than causing the vehicle-mounted device, such as the engine, closely related to running to malfunction.

  The AV apparatus 4 is an apparatus that reproduces an AV source stored in a storage medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), an MD (Mini Disk), a memory card, a hard disk, or a cassette tape. Note that the AV apparatus 4 can not only reproduce the AV source but also receive broadcasts such as radio and television and display music output and video. The AV apparatus 4 includes an audio signal amplifier 8 such as an amplifier that amplifies a signal output from the speaker during reproduction, and can control the driver's volume operation or the audio signal amplifier 8 to increase or decrease the volume output from the speaker. .

  The navigation ECU 5 controls the navigation system that displays the position of the host vehicle and the route to the destination on the display device 9, and can control the brightness (luminosity described later) and contrast of the display device 9. The display device 9 is also used when the AV device 4 reproduces video. The body ECU 6 controls lighting and luminous intensity of headlights and various indoor lamps. In the present embodiment, the body ECU 6 controls the room lamp 10 and the SW lamp 11 that touch the eyes of the driver. The room lamp 10 is, for example, a lamp that is controlled to be turned on and off in conjunction with the opening and closing of a door embedded in a ceiling in front of the windshield. The room lamp 10 is an example, and may be any lamp that can be lit by the driver, such as a door courtesy lamp, a vanity lamp, an LED downlight, and a bottle holder lamp. The SW lamp 11 is a lamp embedded in the engine switch, but may be a lamp embedded in other switches operated by the driver.

  The meter ECU 7 includes indicator lamps such as instruction control of meters such as a remaining fuel meter and a speedometer, a remaining battery indicator lamp, a charge warning lamp for notifying the abnormality of the battery 1, a remaining fuel warning lamp, and a warning lamp with no seat belt attached. 12 lighting and luminous intensity are controlled.

[Control of playback speed of AV source]
A control procedure of the battery state notification system 30 will be described. FIG. 2 is a flowchart of a control procedure in which the battery status notification system 30 slows down the AV source playback speed in accordance with the remaining battery level. The flowchart of FIG. 2 starts when, for example, the ignition is turned on.

  The battery capacity determination means 3a detects the charge / discharge current and temperature of the battery monitor 2 continuously or periodically (S1). Then, the battery capacity determination means 3a determines whether or not the battery remaining amount has decreased by a predetermined amount (S2). The predetermined amount is a capacity for one stage when the battery capacity is divided into, for example, ten stages. If the battery remaining amount has not decreased by a predetermined amount (No in S2), the process returns to step S1 and signal detection from the battery monitor 2 is repeated.

  When the battery remaining amount has decreased by a predetermined amount (Yes in S2), the battery capacity determination means 3a requests the meter ECU 7 to decrease the memory of the battery remaining amount indicator lamp (S3). Then, the mimicry control means 3b sends a mimicry command to the AV apparatus 4 (S4).

  The AV device 4 mimics the malfunction of the AV device 4 due to the battery shortage according to the mimic command. When the AV device 4 malfunctions due to a shortage of battery, the playback of the AV source stored on the CD or DVD may be delayed. The AV device 4 mimics this malfunction and slows the playback speed of the AV source (S5). ).

  In order to slow down the music playback speed, in the case of CD or DVD, the speed of the motor that rotates the disk is slowed down, or when digital data is D / A converted at intervals of several tens of milliseconds. The playback speed is delayed by repeatedly reading data twice. Also, when slowing down the video playback speed, slow down the rotation speed of the motor that rotates the disc, add frames to be played back (draw the same frame every predetermined time), and set the frame rate (number of frames / second). Slow down. Also, digital data or low-frequency signals extracted from the disk may be temporarily stored in a storage device such as a memory or a hard disk, and reproduced and output at a slower speed than usual.

  FIG. 3A is a diagram illustrating an example of the relationship between the remaining battery level and the playback speed of the AV source. In FIG. 3A, the horizontal axis indicates the remaining battery level (usage amount), and the vertical axis indicates the playback speed (1.0 = normal playback speed). For example, playback is performed at the normal playback speed until the remaining battery level is reduced to 30%, and when the remaining battery level is 30% or less, the playback speed is gradually reduced by the control of FIG.

  Since the driver feels malfunction when the remaining battery level is not actually sufficient, the driver can intuitively grasp the decrease in the remaining battery level. In addition, since the driver is gradually notified from the stage where the remaining battery level is still sufficient (30% in FIG. 3A), the driver recognizes the time and recognition that the remaining battery level is decreasing. You can afford to charge the battery until it is charged. Note that the control of the playback speed in FIG. 3 (a) is an example, and the playback speed may be slowed down at a constant rate instead of gradually slowing down the playback speed as shown in FIG. 3 (a). The playback speed may be greatly reduced as the remaining battery level approaches zero.

  In addition, if the normal playback speed is gradually slowed down from the stage where the remaining battery level is still sufficient (30% in FIG. 3A), the slow playback speed continues for a long time and the desired AV source cannot be played back. There is a risk of dissatisfaction. Therefore, as shown in FIG. 3B, the regeneration speed may be slowed down when the remaining amount of the battery is reduced to a state where the battery is nearly exhausted (engine start is possible). In FIG. 3B, when the remaining battery level is reduced to about 10%, the playback speed is relatively extremely slow. Therefore, the driver can surely notice a decrease in the remaining battery level due to the slow playback speed, and can play the AV source at the normal playback speed until then. Further, stop / play may be repeated irregularly.

  In addition, when the driver turns off the air conditioner, for example, and the amount of charge is greater than the amount of discharge and the remaining battery level increases, the playback speed is gradually brought closer to the normal playback speed according to the remaining battery level. In addition, when the vehicle is stopped (engine stopped) and power is consumed and the remaining battery level is reduced, when the engine is started, the playback speed of the AV device 4 is slowed down to notify the decrease in the remaining battery level.

[Volume control]
Then, it is a flowchart figure of the control procedure in which the battery state alerting | reporting system 30 reduces a sound volume according to a battery remaining charge. The flowchart in FIG. 4 starts when the ignition is turned on, for example. In FIG. 4, the same parts as those in FIG.

  The battery capacity determination means 3a detects the charge / discharge current and temperature of the battery monitor 2 continuously or periodically (S1). Then, the battery capacity determination means 3a determines whether or not the battery remaining amount has decreased by a predetermined amount (S2). The predetermined amount is a capacity for one stage when the battery capacity is divided into, for example, ten stages. If the battery remaining amount has not decreased by a predetermined amount (No in S2), the process returns to step S1 and signal detection from the battery monitor 2 is repeated.

  When the battery remaining amount has decreased by a predetermined amount (Yes in S2), the battery capacity determination means 3a requests the meter ECU 7 to decrease the memory of the battery remaining amount indicator lamp (S3). Then, the mimicry control means 3b sends a mimicry command to the AV apparatus 4 (S4).

  The AV device 4 mimics the malfunction of the AV device 4 due to the battery shortage according to the mimic command. When the AV apparatus 4 malfunctions due to a shortage of the battery, the playback sound of the AV source and the volume of the radio, television, etc. may be reduced. The AV apparatus 4 controls the audio signal amplifier 8 to simulate the malfunction and music. And the volume accompanying the video is reduced (S6).

  Since the audio signal amplifier 8 includes a gain control amplifier that variably controls the gain level based on the operation of the volume knob, in order to reduce the volume, for example, the audio signal amplifier 8 sets the gain control amplifier to a small setting. The audio signal is amplified by the power amplifier according to this setting and output from the speaker.

  Assuming that the volume set by the driver is 1.0, the AV device 4 gradually decreases the gain of the gain control amplifier each time the remaining battery level decreases, as in FIG. 3A. To do.

  Therefore, the volume of the driver decreases every time the remaining battery level decreases by a predetermined amount. Therefore, the driver can intuitively grasp the decrease in the remaining battery level by experiencing a malfunction when the remaining battery level is not sufficient. it can. In addition, by gradually notifying the driver from the stage where the remaining battery level is still sufficient, the driver has time to recognize that the remaining battery level is decreasing and the time from recognition to charging. Can have. Even if the driver notices that the volume has decreased and operates the volume knob to increase the volume, it is preferable that the volume remains low, which reduces the remaining battery level. You can feel what you are doing.

  In addition, the volume may be decreased at a constant ratio instead of gradually decreasing the volume, or the volume decrease rate may be increased as the remaining battery level approaches zero. Further, when the remaining battery level is reduced to a state where the battery is almost exhausted (engine start is possible), the volume may be relatively extremely reduced. Further, irregular increase / decrease (including silence) may be repeated.

  When the driver turns off the air conditioner, for example, and the amount of charge is greater than the amount of discharge and the remaining battery level increases, the volume is gradually brought closer to the level set by the driver according to the remaining battery level.

[Control of luminous intensity]
Subsequently, a control procedure for lowering the light intensity of the light source that can be visually recognized by the driver according to the remaining battery capacity will be described with reference to the flowchart of FIG. The flowchart of FIG. 5 starts when, for example, the ignition is turned on. In FIG. 5, the same parts as those in FIG. Here, it is assumed that the light intensity of the display device 9, the room lamp 10, the SW lamp 11 and the indicator lamp 12 (hereinafter simply referred to as “lamps”) serving as a light source that can be visually recognized by the driver is controlled. ECUE5, body ECU6 and meter ECU7 are simply referred to as ECUs without being distinguished.

  The battery capacity determination means 3a detects the charge / discharge current and temperature of the battery monitor 2 continuously or periodically (S1). Then, the battery capacity determination means 3a determines whether or not the battery remaining amount has decreased by a predetermined amount (S2). The predetermined amount is a capacity for one stage when the battery capacity is divided into, for example, ten stages. If the battery remaining amount has not decreased by a predetermined amount (No in S2), the process returns to step S1 and signal detection from the battery monitor 2 is repeated.

  When the battery remaining amount has decreased by a predetermined amount (Yes in S2), the battery capacity determination means 3a requests the meter ECU 7 to decrease the memory of the battery remaining amount indicator lamp (S3). Then, the mimicry control means 3b sends a mimicry command to the ECU (S4).

  The ECU mimics a decrease in light intensity due to battery shortage according to a mimic command. When the lamps malfunction due to battery shortage, the luminous intensity of the lamps may decrease. The ECU mimics this malfunction and decreases the luminous intensity (S7).

  In order to reduce the luminous intensity, for example, the voltage applied to the lamps may be reduced, or the on-duty of the PWM signal may be reduced. Similar to FIG. 3A, the ECU sets the normal light intensity to 1.0, and gradually decreases the light intensity every time the remaining battery capacity decreases.

  Therefore, since the brightness of the lamps decreases every time the remaining battery level decreases by a predetermined amount, the driver intuitively grasps the decrease in the remaining battery level by experiencing a malfunction when the remaining battery level is not sufficient can do. In addition, by gradually notifying the driver from the stage where the remaining battery level is still sufficient, the driver has time to recognize that the remaining battery level is decreasing and the time from recognition to charging. Can have.

  Further, instead of decreasing the luminous intensity in stages, the luminous intensity may be decreased at a constant ratio, or the decreasing rate of the luminous intensity may be increased as the remaining battery level approaches zero. Further, when the remaining battery level is reduced to a state where the battery is nearly exhausted (engine start is possible), the luminous intensity may be made relatively extremely small. Further, irregular flashing may be simulated.

  In addition, when the driver turns off the air conditioner, for example, and the amount of charge is greater than the amount of discharge and the remaining battery level increases, the light intensity is gradually brought closer to the original size according to the remaining battery level.

[Control combining playback speed, volume and intensity]
2, 4, and 5, the playback speed, volume, and luminous intensity are controlled independently, but in the battery status notification system 30, any combination of the playback speed, volume, and luminous intensity, such as playback speed and luminous intensity, is selected. One or all may be controlled. If the playback speed is slowed or the volume is reduced and the light intensity is reduced, a decrease in the remaining battery level can be recognized from a decrease in the playback speed or a decrease in sound volume and a decrease in light intensity. Further, for example, the electrical equipment 20 that simulates malfunction may be increased according to the degree of decrease in the remaining battery level.

[Low battery level due to battery deterioration]
If the battery 1 deteriorates, even if it is charged, the battery 1 is discharged early, making it difficult to start the engine. The battery state notification system 30 of the present embodiment can similarly notify the driver of such battery deterioration by monitoring the remaining battery level. Even if the battery 1 is charged, the remaining amount of the battery decreases immediately, so that the driver can recognize the deterioration of the battery 1 and prompt early replacement.

  According to the battery state notification system 30 of the present embodiment, the driver can intuitively grasp the decrease in the remaining battery level by mimicking the malfunction caused by the decrease in the remaining battery level. In addition, although there is no problem in traveling, in many cases, the electrical components that are desired to be restored at an early stage can be out of order so that the battery 1 must be charged or replaced, and prompt charging is promoted. be able to. Since the electrical equipment that mimics the malfunction is not closely related to driving and driving, the driver does not feel uneasy.

  In the present embodiment, the mimicry control means 3b sends a remaining amount lowering notification command to the electrical component 20 together with the mimicry command. The remaining amount decrease notification command is a command for notifying the electrical component 20 by visual or audible means that the battery remaining amount has decreased by a predetermined amount. When the low battery level notification command is received, for example, the navigation ECU 5 displays a message such as “Low battery level” on the display device 9 or “Electrical component malfunction indicates low battery level”. Or output the voice of the message from the speaker. Further, for example, the meter ECU 7 may notify by turning on the indicator lamp 12 of the combination panel, or may display a mark or a message notifying that the remaining battery level is low on the multi-information display.

[Volume control]
A control procedure in which the battery state notification system 30 decreases the volume in accordance with the remaining battery level and notifies that the remaining battery level has decreased by a predetermined amount in response to the remaining battery level lowering notification command will be described with reference to the flowchart of FIG. The same applies to the playback speed control and luminous intensity control of the AV source. The flowchart in FIG. 6 starts when the ignition is turned on, for example.

  The battery capacity determination means 3a detects the charge / discharge current and temperature of the battery monitor 2 continuously or periodically (S1). Then, the battery capacity determination means 3a determines whether or not the battery remaining amount has decreased by a predetermined amount (S2). The predetermined amount is a capacity for one stage when the battery capacity is divided into, for example, ten stages. If the battery remaining amount has not decreased by a predetermined amount (No in S2), the process returns to step S1 and signal detection from the battery monitor 2 is repeated.

  When the battery remaining amount has decreased by a predetermined amount (Yes in S2), the battery capacity determination means 3a requests the meter ECU 7 to decrease the memory of the battery remaining amount indicator lamp (S3). Then, the mimicry control means 3b sends a mimicry command and a remaining amount drop notification command to the AV apparatus 4 (S4).

  The AV device 4 mimics the malfunction of the AV device 4 due to the battery shortage according to the mimic command. The AV apparatus 4 controls the audio signal amplifier 8 to mimic this malfunction and reduce the volume of music and video (S8). When receiving the mimic command, the audio signal amplifier 8 sets the gain control amplifier to a small value. The audio signal is amplified by the power amplifier according to this setting and output from the speaker.

  Assuming that the volume set by the driver is 1.0, the AV device 4 gradually decreases the gain of the gain control amplifier each time the remaining battery level decreases, as in FIG. 3A. To do.

  Then, for example, the meter ECU 7 displays on the combination panel that the remaining battery level has dropped and outputs a message to that effect (S50).

  Therefore, in addition to the effect of the first embodiment, it is notified visually or audibly that the remaining amount of the battery has been reduced, so that the driver's sound volume is not reduced due to the failure of the AV apparatus 4, but the battery It is possible to recognize that it is due to a decrease in the remaining amount without anxiety and prompt the user to charge or replace the battery 1. Also in the present embodiment, the battery status notification system 30 can be controlled by freely combining the playback speed, volume, and luminous intensity, and the number of times the remaining amount lowering notification command is issued within a predetermined period exceeds a predetermined value. Can notify the driver of the deterioration of the battery 1.

It is an example of the block diagram of a battery state alerting | reporting system. It is a flowchart figure of the control procedure in which a battery status alerting | reporting system slows down the reproduction speed of AV source according to battery remaining charge It is a figure which shows an example of the relationship between a battery remaining charge and the reproduction speed of AV source.
