Description

Technical Field

[0001] The present invention belongs to the technical field of wireless Bluetooth for vehicle refrigerators, and in particular relates to a vehicle refrigerator control method for realizing intelligent control of a vehicle computer by using wireless Bluetooth as a medium. Background Art

[0002] Car refrigerators are becoming more and more popular in the market, and the technology is constantly innovating; currently, most car refrigerators on the market are aftermarket products (purchased later and placed in the car for use) and cannot interact with the car computer, so as to control the car refrigerator from the car computer or obtain relevant working data from the car refrigerator. A very small number of pre-installed (the refrigerator is assembled synchronously when the car is produced) car refrigerators are fixed inside the car and are connected by wiring harnesses, and generally use LIN / CAN for data exchange. There are some shortcomings in the control, and it is not as convenient as the intelligent control in the current home improvement system. Therefore, a car refrigerator control method using wireless Bluetooth as a medium to realize intelligent control of the car computer is provided. Summary of the invention

[0003] In order to solve the defects and shortcomings of the prior art, the purpose of the present invention is to provide a method for controlling a vehicle refrigerator using wireless Bluetooth as the medium to achieve intelligent control of the vehicle computer. Since this method is not restricted by the wiring harness, the vehicle refrigerator using Bluetooth communication makes the wiring harness inside the entire vehicle and the refrigerator simple and tidy on the basis of realizing the function, and also reduces the loss of resources.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a Bluetooth signal transceiver is set in the vehicle electronic control system, and a Bluetooth communication module is set on the car refrigerator; the Bluetooth communication module is wirelessly connected to the Bluetooth signal to realize data interaction.

[0005] After the Bluetooth module is powered on, it is connected and paired with the corresponding Bluetooth device. After pairing, it directly interacts with the vehicle computer to realize the vehicle computer's control of the refrigerator and the reporting of refrigerator data. The refrigerator can be remotely controlled by a mobile phone or other mobile device. When the current data of the refrigerator needs to be obtained, the mobile phone can directly send a request to the vehicle computer to obtain the data, without the need to connect to the refrigerator again for operation; Regarding the control of the local functions of the refrigerator and the control output of each load, when the refrigerator receives the corresponding control signal (working mode, set temperature, power on and off instructions, etc.) sent by the vehicle via Bluetooth, the refrigerator will control the corresponding load control output through its own operating logic.

[0006] Car computer realizes refrigerator refrigeration control: The user adjusts the cooling target temperature on the vehicle side → the vehicle Bluetooth module sends the target temperature data → the refrigerator Bluetooth module receives the vehicle Bluetooth data → the refrigerator main control unit analyzes the received Bluetooth data to make a cooling start and stop judgment → if the current refrigerator temperature is ≧ the received target temperature by 2°C (this value can be set to 1~5°C according to the actual situation), the compressor and fan are turned on for cooling; if the current refrigerator temperature is ≦ the received target temperature, the compressor and fan are turned off for cooling; Car computer realizes refrigerator heating control: The user adjusts the heating target temperature on the vehicle side → the vehicle Bluetooth module sends the target temperature data → the refrigerator Bluetooth module receives the vehicle Bluetooth data → the refrigerator main control unit analyzes the received Bluetooth data to make a heating start and stop judgment → if the current temperature in the refrigerator is ≦ the received target temperature by 2°C (this value can be set to 1~5°C according to the actual situation), the heating wire is turned on for heating; if the current temperature in the refrigerator is ≧ the received target temperature, the heating wire is stopped and turned off; Car computer realizes refrigerator on / off: The user turns on / off the refrigerator on the vehicle side → the vehicle Bluetooth module sends the user's operation command data → the refrigerator Bluetooth module receives the vehicle Bluetooth data → the refrigerator main control unit analyzes the received Bluetooth data and executes the corresponding command → if it is a power-on command, the refrigerator starts and runs normally; if it is a power-off command, the refrigerator shuts down and stops all loads; The refrigerator reports current data: The user operates the refrigerator to set the temperature / turn on and off / open and close the door, etc. → the refrigerator Bluetooth actively sends operation data and commands → the car Bluetooth receives the data and commands from the refrigerator → the car main control analyzes the data and commands → the car updates the data.

[0007] The present invention has the following beneficial effects: 1. The car refrigerator that exchanges data via Bluetooth is not affected by the installation position. It can be installed in a fixed position in the car or moved to other places in the form of quick disassembly. As long as the Bluetooth signals of the car computer and the refrigerator are covered by each other, data can be exchanged between the car computer and the refrigerator to realize the control of various functions.

[0008] 2. Because it is not restricted by wiring harnesses, the Bluetooth communication car refrigerator makes the wiring harnesses of the entire vehicle and the refrigerator simple and tidy on the basis of realizing its functions, and also reduces the loss of resources.
