  Hereinafter, an in-vehicle information recording device according to an embodiment of the present invention will be described with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration of an in-vehicle information recording device according to Embodiment 1 of the present invention.

  In FIG. 1, the in-vehicle information recording apparatus according to the present embodiment includes a battery monitoring unit 12 that monitors a charging state of a battery 11, an antenna 13 and a receiving unit 14 that receive broadcast radio waves, and information received by the receiving unit 14. Is recorded on the storage medium 15 and reproduced from the storage medium 15 as necessary, a communication unit 17 that transmits / receives information related to the reservation with the external device, and a reception unit 14 that receives the information about the reservation with the external device. The calculation unit 20 creates a recording schedule for recording the recorded information, the display unit 18 for displaying the output of the storage / reproduction unit 16 and the output of the calculation unit 20, and the input unit 19 for inputting the recording reservation information. .

  The battery 11 is mounted on the vehicle and supplies power to the in-vehicle information recording device and to start the engine of the vehicle. Therefore, even if the battery 11 consumes power in the in-vehicle information recording device, it is necessary to always ensure a sufficient battery level to start the vehicle engine, and the battery monitoring unit 12 constantly monitors the battery level.

  The storage medium 15 is a medium for storing broadcast radio wave signals such as FM broadcasts and digital terrestrial broadcasts received via the antenna 13 and the receiving unit 14, and may store a large amount of various information such as music and video. Therefore, a large capacity storage medium is desirable. For example, there are a hard disk, a memory card, a readable CD, a DVD, and the like.

  The storage / playback unit 16 writes or reads various information such as music and video in the storage medium 15 as necessary.

  The communication unit 17 receives the recording reservation information transmitted from the outside of the vehicle by the user via a wireless network such as a mobile phone or a DSRC device, the remaining battery level, the execution status of the reservation, and the like to the user.

  The display unit 18 displays information output from the recording / playback unit 16 and a reservation execution status output from the calculation unit 20, and is a liquid crystal display for displaying images, a speaker for outputting sound, or the like.

  The input unit 19 is a touch key for inputting reservation information necessary for recording information, a remote controller, a microphone for voice input, or the like.

  The computing unit 20 determines whether or not the recording reservation is possible based on the remaining battery information from the battery monitoring unit 12, the radio wave reception status information from the receiving unit 14, and the recording reservation information from the input unit 19. Create a recording schedule for information recording. Further, control for transmitting the reservation execution status, radio wave reception status, remaining battery level, etc. to the user via the display unit 18 and the communication unit 17 is also performed.

  In the vehicle information recording apparatus configured as described above, the operation of the vehicle information recording apparatus when the user creates a recording schedule in the vehicle while the engine is stopped will be described with reference to the flowchart of FIG.

  In FIG. 2, the user first inputs reservation information such as a program or keyword desired to be recorded from the input unit 19 (S201).

  Next, the battery monitoring unit 12 determines the current remaining battery level (S202). In order to determine the remaining battery level, it is essential to secure the remaining battery level necessary for starting the engine of the vehicle, and it is desirable to have a slight margin. If there is only enough battery power to start the engine (NO in S202), the display unit 18 displays that the recording reservation cannot be made because the battery power is low (S212). If there is a sufficient remaining battery level to start the engine (YES in S202), the battery available amount is calculated from the difference between the remaining battery level at the current time and the amount of battery required to start the vehicle engine. (S203).

  Next, it is determined in the calculation unit 20 whether or not the next scheduled travel date and time is set by the user (S204). The determination of whether or not the next scheduled travel date / time is set is a step necessary to limit the target period of the recording schedule described later. If the next scheduled travel date / time is set (YES in S204), a reservation is made. The period from the information input date and time to the next scheduled driving date and time is the target period of the recording schedule. If the next scheduled travel date / time is not set (NO in S204), the next scheduled travel date / time is estimated from the past travel history (S205), and the estimated next travel date / time is estimated from the input date / time of the reservation information. The period becomes the target period of the recording schedule.

  Next, the program desired to be recorded is confirmed (S206). When a specific broadcast date and time, program name, or the like is input as reservation information, the program is recorded. If keywords such as “soccer” or “Yokohama” are entered, electronic program guides are received as necessary, keyword searches are performed, and specific programs matching the keywords are recorded. set to target.

  Next, the calculation unit 20 checks the reception status of the broadcast radio wave for each program to be recorded, and determines a recordable program (S207). In the case of a program that cannot be recorded due to poor broadcast radio wave reception status (NO in S207), the display unit 18 displays that the broadcast radio wave reception status is poor and cannot be recorded (S212). If the broadcast radio wave reception is good and the program can be recorded (YES in S207), the estimated battery consumption by recording the program is calculated from the recording time of each program (S208).

  Next, prioritization is performed among programs that can be recorded (S209). The priority order may be set, for example, according to the reception status of the broadcast radio wave, or may be set according to the degree to which the user specifically sets the program and matches the keyword. It can be set according to the viewing frequency, or can be set directly by the user.

  Next, it is determined whether the estimated battery consumption by all programs that can be recorded is within the battery usable amount (S210). When the estimated battery consumption by all the programs that can be recorded exceeds the battery usable amount (NO in S210), the display unit 18 displays that the recording cannot be reserved because the remaining battery level is low (S212). If the estimated battery consumption by all programs that can be recorded does not exceed the battery usable amount (YES in S210), a recording schedule is created (S211).

  Note that the expected battery consumption due to the operation of the in-vehicle information recording apparatus varies depending on the aging of the battery, the ambient temperature, and the like. For example, when an in-vehicle information recording device is operated for one hour, there is a difference in battery consumption between last winter and this summer. Similarly, there is a difference in battery consumption between daytime and nighttime even during the same day. Therefore, when storing the recording schedule in the in-vehicle information recording device, the recording date, recording start time, recording time, etc., which are the fluctuation factors of the battery consumption, are stored as a database, so that In addition, it is possible to estimate the expected battery consumption considering factors such as time zone.

  Next, the created recording schedule is displayed on the display unit 18 (S212), and the operation is terminated.

  FIG. 3 is an explanatory diagram showing an example of the created recording schedule, in which the recording schedule in the period from the input date / time of the reservation information to the next scheduled driving date / time is ascending in order of priority, recording date / time, recording start time The program name, the recording time, and the estimated battery consumption are created so that the sum of the estimated battery consumption for each program to be recorded is less than or equal to the above-mentioned battery usable amount.

  The contents displayed on the display unit 18 include, for example, a predicted value of the remaining battery level after recording, a predicted value of the remaining time that can be recorded in the storage medium 15, and the like in addition to the above-described recording schedule.

  In the above description, the example in which the remaining battery level is determined when the reservation information is input and the recording schedule is created based on the result is described. However, the recording has actually started based on the recording schedule. In some cases, the battery consumption may differ from the initially predicted value due to unforeseen circumstances. After performing some recordings or periodically, check the remaining battery power and When the remaining battery level is low, the recording schedule can be created again, and the creation result or the change in the recording schedule can be displayed on the display unit 18.

  Further, in the above description, when the estimated battery consumption by all programs that can be recorded exceeds the battery usable amount, an example is displayed in which it is displayed on the display unit 18 that recording reservation cannot be made because the remaining battery level is low. However, it is also possible to create a recording schedule as a recording reservation target within a range that does not exceed the battery usable amount from a program with a higher priority of programs to be recorded.

  In the above description, the example in which the created recording schedule is displayed on the display unit 18 has been described. However, the result may be transmitted to an external communication device using the communication unit 17 together with the display on the display unit 18. Is possible.

  As described above, the in-vehicle information recording device of the present embodiment takes into consideration the next scheduled date and time of travel, the amount of battery available, the reception status of radio waves, the priority for each program to be recorded, even when the engine of the vehicle is stopped. Since the recording schedule is created, the reason why the program is not targeted for recording even though the user desires to be recorded is displayed on the display unit, and the user can grasp at the stage of creating the recording schedule.

  In addition, the program registered in the recording schedule can be recorded reliably, and there is no problem that the reserved information cannot be recorded due to a shortage of remaining battery power, etc. despite the reservation. Furthermore, since the remaining battery level is checked after some recording is performed or periodically, the recording schedule can be updated according to the check result.

(Embodiment 2)
The block diagram showing the configuration of the in-vehicle information recording device according to the second embodiment of the present invention is the same as the block diagram showing the configuration of the in-vehicle information recording device according to the first embodiment, and will be omitted.

  In the present embodiment, the operation of the in-vehicle information recording apparatus when the user creates a recording schedule from outside the vehicle while the engine of the vehicle is stopped will be described with reference to the flowchart of FIG.

  In FIG. 4, it is assumed that the communication unit 17 that communicates with an external device via a wireless network such as a mobile phone or a DSRC device is in a state where it can receive power from the battery 11 and receive information from the external device. The communication unit 17 receives reservation information including the date and time of the program that the user desires to record, the program name, the channel, the recording time, and the like (S301).

  Next, the calculation unit 20 calculates the battery consumption required for confirming the contents of the received reservation information and recording for each program whose contents are confirmed (S302). Specifically, when a program name, recording date, etc. are input, the program is to be recorded, and when a keyword is input, an electronic program guide is received as necessary and a keyword search is performed. A specific program that matches the keyword is to be recorded, and the estimated battery consumption is calculated by summing up the battery consumption of each program.

  Next, the battery remaining amount at the present time is determined (S303). If there is only a battery level sufficient to start the engine (NO in S303), the display unit 18 displays that the recording reservation cannot be made because the battery level is low (S307). When there is a sufficient remaining battery capacity to start the engine (YES in S303), the radio wave reception status for each program to be recorded is determined (S304). In the case of a program that cannot be recorded due to poor broadcast radio wave reception status (NO in S304), the display unit 18 displays that the broadcast radio wave reception status is bad and cannot be recorded (S307). If the broadcast radio wave reception status is good and the program is recordable (YES in S304), priorities are set among the recordable programs (S305).

  Next, a recording schedule shown in FIG. 3 is created in the order of program priority so that the expected battery consumption is within the battery usable amount, for example, in the same manner as in the first embodiment (S306). Next, the created recording schedule is transmitted to the user using the communication unit 17 (S307), and the operation ends.

  The contents to be transmitted to the user include, for example, a predicted value of the remaining battery level after recording and a predicted value of the remaining time that can be recorded in the storage medium 15 in addition to the created recording schedule.

  As described above, the in-vehicle information recording apparatus of the present embodiment receives the user reservation information transmitted from outside the vehicle via the communication unit 17 even when the vehicle engine is stopped and the user is not in the vehicle. In order to create a recording schedule in consideration of the remaining battery level, estimated battery consumption, radio wave reception status, priority for each program to be recorded, etc., and to send the creation result to the user via the communication unit 17, The user can grasp whether or not the recording reservation of the desired information is possible at the stage of creating the recording schedule. Furthermore, there is no problem that the reserved information cannot be recorded due to a shortage of the remaining battery power despite the reservation.

  As described above, the in-vehicle information recording apparatus according to the present invention creates the information recording schedule even when the engine of the vehicle is stopped or when the user is not in the vehicle. It is possible to solve the problem that reserved information cannot be recorded due to shortage, etc., and it is possible to reliably record the information desired by the user, equipped with a video recorder device, a hard disk recorder, an MD device for recording music, etc. It is useful as an in-vehicle information recording device such as a car audio.
