  1, reference numeral 1 indicates a configuration of a vehicle-side information communication system mounted on the host vehicle, and reference numeral 2 indicates a configuration of a store-side information communication system. The vehicle-side information communication system 1 and the store-side information communication are illustrated. The system 2 is configured such that information can be transmitted and received by the communication units 4 and 5 provided in the system 2 via the mobile phone network 3 as a communication network.

  The vehicle-side information communication system 1 mainly includes a communication unit 4, a voice recognition unit 6, a microphone 7, a speaker 8, and a liquid crystal display 9.

  The communication unit 4 includes an antenna, a transmitter / receiver, etc., and transmits / receives information to / from the voice recognition unit 6 by transmitting / receiving information to / from the communication unit 5 of the store side information communication system 2 via the mobile phone network 3. It is provided as a mobile communication means for performing.

  The voice recognition unit 6 recognizes a voice of a user such as a driver inputted by the microphone 7 according to a program for order by voice recognition described later, determines the order of the driver, and transmits it to the store side information communication system 2. It is provided as voice recognition means. Here, voice recognition is performed while switching between a word dictionary preset in the voice recognition unit 6 and a word dictionary transmitted from the store-side information communication system 2, and voice input of the driver is performed by the speaker 8. Based on the voice output (voice guide) and the guide display by the liquid crystal display 9, it is executed in an interactive manner. Information such as a guide display displayed on the liquid crystal display 9 is transmitted from the store side information communication system 2 as necessary.

  The store side information communication system 2 is provided as a base station, and includes a communication unit 5 including an antenna, a transceiver, and the like, a store 10 including the communication unit 5, and a server 11.

  In the first embodiment, for example, as shown in FIG. 2, the store 10 connects a plurality of (here, four stores A, B, C, and D) stores by a wireless LAN (Local Area Network) or the like. The server 11 is provided in a store group (store A in FIG. 2) which is the center of the stores. And the store side information communication system 2 is unique to each store name list and each store in response to a request from the vehicle side information communication system 1 with respect to the vehicle side information communication system 1 mounted on the host vehicle V0. The screen information and the word dictionary can be transmitted, and when order information is transmitted from the vehicle-side information communication system 1, the order information is transmitted to the corresponding store, and the store that received the order Can cook products (dish) according to the order.

Next, an order program by voice recognition executed in the vehicle-side information communication system 1 will be described with reference to the flowchart of FIG.
First, in step (hereinafter abbreviated as “S”) 101, when the driver inputs a voice input, for example, “I want to order a meal”, the process proceeds to S102, where store information is downloaded from the store-side information communication system 2. The process proceeds to S103, where, for example, a screen display of store information classified as a family restaurant, fast food, or the like as shown in FIG. 4 is performed.

  Next, the process proceeds to S104, where a pre-recorded voice output, for example, a guide voice such as “Please say the store name” is output.

  Thereafter, the process proceeds to S105, and if the driver inputs a voice input, for example, the voice "AAAAA of family restaurant", the process proceeds to S106 and a word for voice recognition for ordering the menu of "AAAAA of family restaurant". The dictionary is downloaded from the server 11 of the store side information communication system 2. For example, as shown in FIG. 5, the word dictionary is configured by storing words specific to the conversation scene at the time of order such as the name and number of each menu and “request” for each menu type.

  Next, the process proceeds to S107, and the screen information unique to the store for ordering the menu of “Family restaurant AAAAA” is downloaded from the server 11 of the store side information communication system 2. For example, as shown in FIG. 6, this screen information is a screen on which the words of the downloaded word dictionary are displayed as a menu. Each screen type is separated by a tab and is formed with improved visibility. Yes. Also, since it is unique to the store, for example, in the case of a French restaurant, the one that designed the scenery of France, or in the case of a fast food restaurant, the original character of the store etc. is displayed to stimulate the purchase. Such a design is given.

  In step S108, the word dictionary downloaded in step S106 is set in place of the normal word dictionary. In step S109, the store-specific screen information downloaded in step S107 is changed from the currently displayed store list screen. Switch.

  Next, the process proceeds to S110, and a pre-recorded voice output, for example, a guide voice such as “Please say an order” is output.

  In step S111, the driver inputs a voice, for example, “Request one PP1 and two PP2”.

  Next, the process proceeds to S112, and an order confirmation voice is output by voice input in S111. For example, “One PP1 and two PP2.”

  Then, the process proceeds to S113, and when a confirmation voice, for example, “Yes” or “No” is input by the driver, the process proceeds to S114, where the confirmation voice is determined by the driver input in S113, and if the order is correct ( If “yes”, the process proceeds to S115, and if the order is not correct (“no”), the processing from S110 is repeated again.

  If the order is correct as a result of the determination in S114 and the process proceeds to S115, it is determined whether or not the tab dividing the menu is the last.

  If the tab is not the last, that is, in the example of FIG. 6, in the case of “food” or “drink”, the process proceeds to S116, the tab is switched to the next tab, and the menu of the cut tab is set to S110. Repeat the process from.

  If the tab is the last as a result of the determination in S115, that is, in the example of FIG. 6, in the case of “other”, the process proceeds to S117, and the order completion confirmation voice, for example, “corrects the order” Is output.

  Then, the process proceeds to S118, and when an order completion confirmation voice by the driver, for example, “Yes” or “No” is input, the process proceeds to S119, where the order completion confirmation voice by the driver input in S118 is determined. If there is a correction (if “yes”), the processing from S109 is repeated again. Conversely, if there is no order correction (if “No”), the process proceeds to S120, where the determined order information is transmitted to the store side information communication system 2 and the program exits. As a result, when the store-side information communication system 2 receives the order information from the vehicle-side information communication system 1, the store-side information communication system 2 transmits the order information to the corresponding store, and the store that has received the order information prepares a dish corresponding to the order. When cooking and the driver arrives, it becomes possible to start cooking. In addition, it is desirable that the cost is settled by well-known electronic payment when the driver transmits the order information and the store-side information communication system 2 receives the order information.

  Thus, according to the first embodiment, the driver can place an order by voice while in the vehicle, so that the operability of the system can be remarkably improved. At this time, the word dictionary used for speech recognition is the one transmitted from the store, so the product unique to each store is changed even if it is a coined word. However, it can be recognized quickly with a high recognition rate.

  Next, FIGS. 7 and 8 show a second embodiment of the present invention, FIG. 7 is an explanatory diagram of the own vehicle and the store, and FIG. 8 is a flowchart of an order program by voice recognition. The second embodiment differs from the first embodiment in that the second embodiment communicates with one store using a short-range wireless communication network, and the store is configured as a drive-through store. Since the configuration is the same, the same reference numerals are used and description thereof is omitted.

  That is, as shown in FIG. 7, the store 10 is provided with a space around the periphery from which the vehicle can pass from the entrance to the exit while waiting for the turn. When the vehicle enters from the entrance, broadcast data (data transmitted to the vehicle supporting the system described in the present embodiment) transmitted from the communication unit 5 of the store-side information communication system 2 is transmitted to the vehicle-side information. It is received by the communication system 1 (only the vehicle is shown; details are the same as in the first embodiment), and an order by voice recognition can be performed according to an order program by voice recognition to be described later.

Next, an order program by voice recognition executed in the vehicle-side information communication system 1 will be described with reference to the flowchart of FIG.
When the vehicle enters the entrance, broadcast data is received from the communication unit 5 of the store-side information communication system 2 in S201, and response data for the broadcast data received in S202 is transmitted.

  Next, in S203, a word dictionary for speech recognition for ordering the menu is downloaded from the server 11 of the store side information communication system 2. In this word dictionary, as shown in FIG. 5, for example, as shown in FIG. 5, words specific to the conversation scene at the time of order such as the name and number of each menu and “request” are stored in memory for each type of menu. Has been configured.

  Next, it progresses to S204 and the screen information intrinsic | native to the store for ordering a new is downloaded from the server 11 of the store side information communication system 2. FIG. This screen information is a screen on which the words of the downloaded word dictionary are displayed as a menu described in the first embodiment, for example, as shown in FIG. It is formed with improved properties. Further, since it is unique to the store, for example, in the case of a fast food store, an original character or the like of the store is displayed and a design that stimulates purchase is applied.

  In step S205, the word dictionary downloaded in step S203 is set in place of the normal word dictionary. In step S206, the current display screen is switched to the store-specific screen information downloaded in step S204.

  Next, the process proceeds to S207, where a pre-recorded voice output, for example, a guide voice such as “Please say an order” is output.

  In step S208, the driver inputs a voice, for example, “Request one PP1 and two PP2”.

  Next, the process proceeds to S209, and an order confirmation voice is output by voice input in S208. For example, “One PP1 and two PP2.”

  Then, the process proceeds to S210, and if a confirmation voice, for example, “Yes” or “No” is input by the driver, the process proceeds to S211 and the confirmation voice is determined by the driver input in S210, and if the order is correct ( If “yes”, the process proceeds to S212. If the order is not correct (“no”), the processing from S207 is repeated again.

  If the order is correct as a result of the determination in S211, and the process proceeds to S212, it is determined whether or not the tab dividing the menu is the last.

  If the tab is not the last, that is, in the example of FIG. 6, in the case of “food” or “drink”, the process proceeds to S213, the tab is switched to the next tab, and the menu of the cut tab is S207. Repeat the process from.

  If the tab is the last as a result of the determination in S212, that is, in the example of FIG. 6, in the case of “other”, the process proceeds to S214, and the order completion confirmation voice, for example, “corrects the order” Is output.

  Then, the process proceeds to S215, and when the order completion confirmation voice by the driver, for example, “Yes” or “No” is input, the process proceeds to S216, and the order completion confirmation voice by the driver input in S215 is determined. If there is a correction (if “yes”), the processing from S206 is repeated again. On the contrary, if there is no order correction (if “No”), the process proceeds to S217, and the determined order information is transmitted to the communication unit 5 of the store side information communication system 2 to exit the program. Thereby, when the store-side information communication system 2 receives the order information from the vehicle-side information communication system 1, the dish corresponding to the order is prepared for cooking and delivered to the driver when the driver reaches the exit. The cost may be settled by a well-known electronic payment when the driver sends the order information and the store-side information communication system 2 receives the order information, or in exchange for the product at the exit. It is also good.

  Thus, according to the second embodiment, as in the first embodiment, the driver can place an order by voice while still in the vehicle, so that the operability of the system can be remarkably improved. At this time, the word dictionary used for speech recognition is the one transmitted from the store, so the product unique to each store is changed even if it is a coined word. However, it can be recognized quickly with a high recognition rate.

  In addition, although the above-mentioned 1st and 2nd embodiment illustrated about the shop which uses a dish as a goods, it is not restricted to this. For example, in the first form, the store is a clothing store, and the menu is divided into men's clothing, women's clothing, T-shirts, Y-shirts, etc., and some desired clothing is prepared before the driver arrives. You can also. Similarly, it can be applied to accessory stores. Furthermore, in the second embodiment, the store can be a cash dispenser such as a bank and can be applied to various bank procedures.
