The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] In the description of the present invention, "several" means one or more, "more" means two or more, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0024] Working principle of capsule coffee machine: users put coffee capsules into the special slot of capsule coffee machine. Water heating: the heater inside the coffee machine heats the water in the water tank to a suitable temperature (usually about 92℃). High-pressure extraction: the pressure water pump pressurizes the hot water, and then injects it into the capsule through the pinhole at the bottom of the capsule. The high-pressure water flow contacts the coffee powder and extracts the coffee liquid. This process is usually accompanied by the buildup of pressure in the capsule until the aluminum foil cover is broken and the coffee liquid flows out. Enjoying coffee: the extracted coffee liquid goes directly into a cup or other container, and users can enjoy fresh coffee.

[0025] Most existing coffee machines use steam boilers as a way to heat coffee, and there are some problems that need to be solved: the steam-brewed coffee is not hot, the brewing head jets, the machine makes noises, etc. The flow rate is too slow when extracting coffee, which may be caused by too much coffee powder, too high a filling pressure, or the coffee powder is ground too finely; the flow rate is too fast when extracting coffee, which may be caused by too little coffee powder, too low a filling pressure, or the coffee powder is ground too coarsely, and the steam discharge from the steam pipe is uneven, etc.

[0026] It is not convenient for the driver to operate the in-vehicle coffee machine during driving, and to make coffee that suits the taste, many operating parameters need to be input. Therefore, the driver needs to operate the coffee machine in too many steps during driving, which may easily lead to dangerous driving of the vehicle. In addition, it takes a long time to select the operating parameters of the coffee machine, and the coffee cannot be made as soon as possible.

[0027] The embodiment of the present invention connects the vehicle-mounted coffee machine to the automobile central control system, and uses the voice interaction function of the automobile central control system to control the vehicle-mounted coffee machine. Since voice input requires specific coffee making information, such as coffee type, coffee milk and sugar quantity and other specific data, in general, the user needs to complete voice input of all coffee making information to start the coffee machine for coffee making. The embodiment of the present invention analyzes the keyword types and divides the keywords into coffee keywords, coffee type keywords and coffee milk and sugar keywords. When the user's voice instruction only includes the coffee keyword, the vehicle-mounted coffee machine is immediately started to perform water injection and heating operations, and waits for specific coffee type information and coffee milk and sugar information. This not only saves time, but also the coffee machine has already started water injection and heating operations when the user selects the coffee type and coffee milk and sugar quantity, and the automobile central control system simultaneously obtains the status information of the vehicle-mounted coffee machine, guides the user to select specific coffee making information through voice and interactive interface, and provides users with a better interactive experience.
