(1) Each Configuration FIG. 1 is a block diagram showing an embodiment of an audio device 100 of the present invention. As shown in FIG. 1, an audio device 100 according to the present embodiment includes a vehicle position detecting unit 1, a vehicle situation detecting unit 10, a audio control unit 2, and a broadcast information providing unit 3 attached thereto. ing.

<Vehicle position detecting means> Vehicle position detecting means 1
Detects the position of the moving vehicle. As this detecting means, a commonly used car navigation system such as a means for receiving a radio wave transmitted from a positioning satellite using a GPS antenna and positioning the current position of a moving body such as a vehicle as absolute position information. The system can be used. Further, the position of the vehicle may be measured using autonomous navigation that estimates the current position by a cumulative calculation method based on positioning data input from a gyro sensor and a distance sensor attached to wheels. Further, the detection timing may be detected at a specific timing, may be detected at fixed time intervals, or may be detected continuously. By performing detection at regular time intervals or continuously, it is possible to predict where the vehicle is heading and how close the vehicle is to a position where broadcast information should be stored. Based on the detection result, the vehicle position detecting means 1 not only determines the current position by setting the route of the occupant of the vehicle including the driver, but also memorizes and learns the normal traveling process, but also determines the position to which the driver is heading and to the specific position. It also has a function that can predict the approach of a vehicle.

<Vehicle situation detecting means> Vehicle situation detecting means 1
Numeral 0 is a means for detecting the state of the vehicle, stopping or running, and other conditions of the vehicle. Means for detecting the condition of the vehicle include engine on / off whether the engine of the vehicle is running or stopped, turning on / off of a switch key including an accessory switch which is a power source of an electric system for supplying power to the audio device 100 and the like. For example, both means for directly detecting the condition of the vehicle, such as changing the shift lever to the parking range, attaching and detaching the seat belt, and the like, indirectly detecting the condition of the vehicle from the condition of the occupant of the vehicle including the driver are considered. Can be

<Audio Control Unit> The audio control unit 2 has a storage / reproduction determining unit 21, a command unit 22, a position information storage unit 23, and an input unit 24.

Storage / reproduction judging section 21 The storage / reproduction judging section 21 judges whether to store and / or reproduce broadcast information in accordance with the detection result detected by the vehicle position detecting means and / or the vehicle state detecting means. This determination is transmitted to the broadcast information providing unit 3 via the command unit 22 as a command to store and / or reproduce the broadcast information. For example, based on the detection result that the vehicle is at the gas station, the vehicle position detecting means 1 predicts that the power will be turned off at the time of refueling, that is, that the viewing of the broadcast information will be temporarily stopped, and the vehicle is detected at the gas station. If it is located, it is determined that the broadcast information is stored. This determination may be made in advance by the storage / reproduction determining unit 21 associating the position information of the gas station with the command information for storing the broadcast information, or may be stored as position information in the position information storage unit 23 described later. It may be. Here, a gas station is taken as an example, but a parking lot of a store, a store of a drive-through system, or the like can be arbitrarily set. This information is input from the input unit 24 to the storage / reproduction determination unit 21 and the position information storage unit 23.

The storage / reproduction judging section 21 has a reproduction speed adjustment function 211, a delay time calculation function 212, a reproduction section switching function 213, and a vehicle status confirmation function 214. These will be described.

Playback speed adjustment function 211: The playback speed adjustment function 211 is a function for adjusting the playback speed when the broadcast information providing means 3 plays back the stored broadcast information. This function performs double-speed reproduction, slow-motion reproduction, skip reproduction, and the like, as in the normal audio device 100, and increases or decreases the reproduction speed.

In order to reproduce the temporarily interrupted broadcast information and catch up with the contents of the current broadcast information, it is conceivable to increase the reproduction speed or to skip information unnecessary for the user such as commercials. Adjustment function 21
1 makes this adjustment.

Delay time calculation function 212: The delay time calculation function 212 calculates how long the broadcast information reproduced by the broadcast information providing means 3 is delayed compared to the actual broadcast information (broadcast information on the air). Function. When detecting the suspension of the vehicle from the position or the situation of the vehicle, the memory reproduction determination unit 21 stores the broadcast information to be interrupted, the driver returns to the driver's seat, resumes driving, and the broadcast information can be viewed. If so, the reproduction of the stored broadcast information is started. At the beginning of the reproduction, the contents of the broadcast information being reproduced are naturally compared with the contents of the broadcast information on the air. The occupant of the vehicle including the driver views the broadcast information being reproduced, and the audio device 100 receives the broadcast information on the air and keeps storing it. This storage is performed until the contents of the broadcast information being reproduced catch up with the contents of the on-air broadcast information.

The delay time calculation function 212 provides a broadcast time (on-air time) of the broadcast information being reproduced (when the broadcast information is not included in the broadcast information,
00 is acquired from the internal timer and stored), and the current time is compared with the difference to calculate the delay time. If the storage end time of the broadcast information has already been obtained, a delay time is calculated from the recording end time and the current time. The delay time is calculated sequentially because the delay time changes when the reproduction speed is adjusted. A method for calculating the delay time will be described.

[0057]

[Equation 1] Current delay time = delay time− (reproduction speed−
1.0) × reproduction time The delay time is a delay time at the beginning of reproduction, and can also be said to be a time during which viewing of broadcast information was interrupted. In this case, when reproducing at double speed, the reproduction speed is 2.0.

When the playback speed adjusting function 211 is operating, the playback speed is faster or slower than the actual broadcast speed, so the delay time is calculated sequentially. This delay time is indicated to the user by an output means such as a display, and the user can know how much the currently heard (reproduced) broadcast information is behind the actual broadcast information. Also, this delay time is 0 or 0
, It can be considered that the content of the reproduced broadcast information has caught up with the content of the actual broadcast information.

Playback unit switching function 213: The playback unit switching function 213 stops storing broadcast information when the delay time calculated by the delay time calculation function 212 described above approaches 0 or 0, and plays back the broadcast information. This is a means for stopping and switching the received broadcast information to the received broadcast to be provided as it is to the occupants of the vehicle including the driver. If it is possible to catch up with the broadcast information, there is no need to temporarily store and reproduce the broadcast information.

This is information in which the scheduled stop position of the vehicle is associated with the estimated stop time, and includes a part or all of the information shown in FIG. The position information refers to all information necessary for the storage / reproduction determining unit 21 to determine whether to store and / or reproduce the broadcast information.

As shown in FIG. 2, each position A, B, C, D,
E is an abbreviation for code data indicating a position. For example, to describe position A, position A is home. Stopping at home is considered to be after returning home, and it is unlikely that the vehicle will be temporarily stopped. The estimated stop time that will stop at home is t
A is a place where the vehicle is stopped for a long time. As described above, the location information may be such that the information indicating whether the vehicle is stopped for a long time or the location where the vehicle is stopped for a short time is associated with the location information for each location.

In evaluating the predicted stop time,
A threshold value t1 may be provided to determine whether storage and / or reproduction of broadcast information is on or off depending on whether the predicted stoppage time exceeds or does not exceed the threshold value t1. At the position A, the predicted stoppage time is tA, which exceeds the threshold value t1, so that it can be determined that the moving object (vehicle) is not moved for the time t1, and the storage / reproduction determination unit 21 determines that storage of the broadcast information is unnecessary.

On the other hand, taking position E as an example, position E is a gas station. The predicted stop time is tE. This place can be stored as a place where the vehicle stops for a short time, and since the predicted stop time tE is smaller than the threshold value t1, it can be determined that the broadcast information is stored. These pieces of information may be stored in the position information storage unit 23, may be included in the storage / reproduction determination unit 21 as a determination criterion, or may be included in a detection result detected by the vehicle position detection unit 1.

(3) Operation Next, the operation of the present embodiment will be described. <Storage Process> FIG. 3 is a flowchart showing a control procedure of the broadcast information storage process of the present embodiment. First. The vehicle status detecting means 2 is activated (step 1), and acquires information on the vehicle status (step 2). If the detection result indicates that the vehicle is stopped, the process proceeds to step 5, and if not, the process returns to step 3 to continue detecting the vehicle status (step 4). After detecting that the vehicle is stopped, the vehicle position detecting means is activated (step 5). When the vehicle position information is acquired (step 6), the audio control means 2 or the storage / reproduction judging unit 21 in the audio control means refers to the position information based on the vehicle position information and stops the moving body for a short time with the vehicle position. Determine if it is a place.

If it is not the place where the short-term moving object (vehicle) is stopped, the storage / reproduction determining unit 21 determines that the storage of the broadcast information is not started (step 9). On the other hand, when it is determined that the vehicle position is a place where the moving object (vehicle) is stopped for a short time, the storage / reproduction determination unit 21 determines that storage of the broadcast information is started (step 8). A command to store broadcast information is transmitted to the reproducing unit 31 in the broadcast information providing unit 3 via the command unit 22 (step 10). Upon receiving this instruction, the reproducing unit 31 starts storing the broadcast (step 11). Note that this embodiment is an embodiment relating to the audio device 100, but the broadcast information providing method of the present invention also has a similar effect.

<Reproduction Process> FIG. 4 is a flowchart showing a control procedure of the reproduction process of the broadcast information of the present embodiment.
When the vehicle status detecting means 10 is activated (step 22),
The vehicle status detecting means 10 acquires information on the vehicle status (step 23). Whether or not the vehicle has started traveling can be detected based on the vehicle status information. Although not shown, the vehicle position detecting means 1 can also detect the traveling start of the vehicle. At this time, either the vehicle position detecting means 1 or the vehicle state detecting means 10 may be activated, or both may be activated. When both are activated, the start of traveling of the vehicle can be detected with high accuracy.

If the information that the vehicle has started running cannot be detected, the process returns to step 23 to detect information on the vehicle status. On the other hand, if the start of the vehicle is detected, the storage / reproduction determining unit 21 determines that the reproduction of the broadcast information is to be started (step 25). Based on this determination, the reproduction of the broadcast information is transmitted to the reproduction unit 31 via the command unit 22 (step 26). Based on this command, the reproducing unit 31 starts reproducing the stored broadcast information. Note that this embodiment is an embodiment relating to the audio device 100, but the broadcast information providing method of the present invention also has a similar effect.

<Storage Reproduction Switching Process> FIG. 5 is a flowchart showing a control procedure of the broadcast information storage / reproduction switching process of the present embodiment. When the reproducing unit 31 starts reproducing the broadcast information (single speed, fast forward, double speed) (step 3
2), sending time calculation function 212 in storage / reproduction determination unit 21
Is activated (step 33), and the delay time is calculated (step 34). It is determined whether or not the calculated delay time T approaches 0 or 0 (step 35). When the delay time approaches 0 or approaches 0, it is considered that the broadcast information being reproduced has caught up with the broadcast information being on the air, and the storage / reproduction determination unit 21 (reproduction unit switching function 213) stores the broadcast information. It is determined that the reproduction has stopped (step 36). Based on this determination, the instruction unit 22 instructs the reproduction unit 31 to store and reproduce the broadcast information (step 37). Upon receiving this command, the broadcast information received and output by the broadcast information receiving and outputting section 32 is provided from the broadcast information providing means 3 in real time (step 38). On the other hand, while the delay time T does not become 0 or does not gradually approach 0, the process returns to step 34, and the delay time is sequentially calculated. In this case, storage and reproduction of the broadcast information will be continued. Note that this embodiment is an embodiment relating to the audio device 100, but the broadcast information providing method of the present invention also has a similar effect.
