Description

Technical Field

[0001] The present invention relates to the technical field of intelligent vehicle control, and particularly relates to a vehicle machine mode switching system, method and vehicle. Background Technique

[0002] With the rapid development of automotive intelligent technologies, the vehicle machine system has become an indispensable core component of modern vehicles, providing users with diversified functions such as navigation, entertainment, and communication. In the development and maintenance process of the vehicle machine system, system debugging is a key link to ensure stable function and performance optimization. However, traditional debugging methods are not only cumbersome to operate but also may interfere with the daily use experience of users. Therefore, how to efficiently and conveniently switch between the daily working mode and the debugging mode of the vehicle machine system has become a technical problem to be solved urgently.

[0003] The traditional way to enable vehicle machine ADB (Android Debug Bridge, which is a multi-functional command-line tool that allows developers to communicate with connected Android devices or emulators. ADB is part of the Android software development kit and is mainly used for developing and debugging Android applications) debugging usually requires developers to enter the factory settings interface through a series of complex system setting interface operations and activate the ADB debugging mode by entering a password. This process not only requires developers to obtain the password in advance but also involves multiple manual steps, greatly reducing the debugging efficiency. In addition, the storage and transmission of the password may also bring security risks.

[0004] In view of the above problems, the industry has been exploring more efficient and secure vehicle machine mode switching methods. Although existing technical solutions have tried to generate and verify passwords for ADB debugging through a cloud authentication background and RSA encryption algorithm, thus improving security to a certain extent, these solutions mainly focus on the ADB debugging authentication method and the control of storage media, and do not comprehensively involve the specific control method of vehicle machine mode switching.

[0005] Therefore, it is necessary to develop a new vehicle machine mode switching system, method and vehicle. Summary of the Invention

[0006] The purpose of the present invention is to provide a vehicle machine mode switching system, method and vehicle to achieve rapid switching of the vehicle machine among multiple modes.

[0007] In a first aspect, a vehicle machine mode switching system according to the present invention includes: A host computer configured to send different control signals; A vehicle machine, whose modes at least include a working mode, a debugging preparation mode and a debugging mode; A first storage device for storing files to be played or viewed in the working mode; A second storage device for storing the vehicle head unit debugging configuration file; A mode switching module, which is respectively connected to the host computer, the vehicle head unit, the first storage device and the second storage device. The mode switching module receives the control signal sent by the host computer to realize the switching of the vehicle head unit between different modes.

[0008] Optionally, the mode switching module includes a first relay, a second relay and a third relay, where: The first relay is connected between the host computer and the vehicle head unit, and is used to control the on / off of the communication connection between the vehicle head unit and the host computer; The second relay is connected between the vehicle head unit and the first storage device, and is used to control the on / off of the communication connection between the vehicle head unit and the first storage device; The third relay is connected between the vehicle head unit and the second storage device, and is used to control the on / off of the communication connection between the vehicle head unit and the second storage device. Through the design of the first relay, the second relay and the third relay, the system can accurately control the connection status between the vehicle head unit and the host computer, the first storage device and the second storage device. This hardware design not only simplifies the complexity of the system, but also improves the reliability and accuracy of switching the vehicle head unit mode. As an electrical switch, the relay can quickly respond to the control signal of the host computer, so as to realize the quick switching of the vehicle head unit working mode.

[0009] Optionally, when the second relay is closed and the first relay and the third relay are open, the vehicle head unit enters the working mode and can access the files in the first storage device. The host computer controls the second relay to be closed, and the first relay and the third relay to be open, so that the vehicle head unit switches from the debugging mode to the working mode.

[0010] Optionally, when the third relay is closed and the first relay and the second relay are open, the vehicle head unit enters the debugging preparation mode and can read the vehicle head unit debugging configuration file stored in the second storage device. The host computer controls the third relay to be closed, and the first relay and the second relay to be open, so that the vehicle head unit switches from the working mode to the debugging preparation mode.

[0011] Optionally, when the vehicle head unit has read the vehicle head unit debugging configuration file, and the first relay is closed, and the second relay and the third relay are open, the vehicle head unit enters the debugging mode and allows ADB debugging. The host computer controls the first relay to be closed, and the second relay and the third relay to be open, so that the vehicle head unit switches from the debugging preparation mode to the debugging mode.

[0012] Optionally, the ADB debugging includes at least one of executing ADB commands, viewing logs, and installing applications. These operations are crucial for the development and maintenance of in-vehicle units. By integrating the ADB debugging function, the system can support more comprehensive debugging requirements, thereby improving the efficiency and accuracy of development and maintenance.

[0013] Optionally, the host computer is a laptop or desktop computer loaded with Python programming, used to control the on / off states of the first relay, the second relay, and the third relay. This enables the system to flexibly control the on / off states of each relay and the working mode of the in-vehicle unit through Python scripts. This design not only improves the scalability and automation of the system but also allows debuggers and developers to customize the control logic and functions as needed. In addition, Python, as a widely used programming language, has rich resources and community support, which further improves the development and maintenance efficiency of the system.

[0014] In a second aspect, a method for switching the mode of an in-vehicle unit according to the present invention uses the in-vehicle unit mode switching system as described in the present invention. The method includes the following steps: Sending a control signal from the host computer to the mode switching module; The mode switching module switches the mode of the in-vehicle unit according to the received control signal; Among them, the in-vehicle unit can access and play or view files stored in the first storage device in the working mode, read the in-vehicle unit debugging configuration file stored in the second storage device in the debugging preparation mode, and allow ADB debugging in the debugging mode.

[0015] Optionally, after entering the debugging preparation mode, the in-vehicle unit debugging configuration file is automatically loaded by restarting the in-vehicle unit. By adding a debugging preparation mode between the debugging mode and the working mode and automatically loading the in-vehicle unit debugging configuration file by restarting the in-vehicle unit, the preparation work before debugging is simplified and the debugging efficiency is improved.

[0016] In a third aspect, a vehicle according to the present invention uses the in-vehicle unit mode switching system as described in the present invention.

[0017] Advantages of the present invention: The in-vehicle unit mode switching system, method, and vehicle according to the present invention achieve rapid switching of the in-vehicle unit among multiple modes (including the working mode, the debugging preparation mode, and the debugging mode) through simple hardware design and software control, which not only improves the development and maintenance efficiency but also maintains the normal user experience.

The first end of the first coil is connected to the host computer 1, and the second end of the first coil is grounded to form a first control loop. When the control signal sent by the host computer 1 received by the first coil is an "enter debug mode signal", that is, the first coil is powered on. After the first coil is powered on, it controls the conduction of the first contact switch, so as to establish a communication connection between the vehicle computer 7 and the host computer 1, allowing ADB debugging.

When controlling the second coil to be powered off, that is, the action of simulating the removal of the first storage device 5 is realized.

[0024] As Figure 1 shown, in a possible embodiment, the third relay 4 is connected between the vehicle computer 7 and the second storage device 6 and is used to control the on / off of the communication connection between the vehicle computer 7 and the second storage device 6. Among them, the third relay 4 includes a third coil and a third contact switch. The third contact switch is connected between the vehicle computer 7 and the second storage device 6.

During the process of restarting the vehicle computer 7, the vehicle computer 7 can read the vehicle computer debug configuration file stored in the second storage device 6. When controlling the third coil to be powered off, that is, the action of simulating the removal of the second storage device 6 is realized.

This hardware design not only simplifies the complexity of the system but also improves the reliability and accuracy of switching the mode of the in-vehicle unit 7. As an electrical switch, the relay can quickly respond to the control signal of the host computer 1, thus realizing the rapid switching of the working mode of the in-vehicle unit 7.

[0029] In a possible embodiment, ADB debugging includes at least one of the operations of executing ADB commands, viewing logs, and installing applications. These operations are crucial for the development and maintenance of the in-vehicle unit 7. By integrating the ADB debugging function, the system can support more comprehensive debugging requirements, thus improving the efficiency and accuracy of development and maintenance.

This enables the system to flexibly control the on / off of each relay and the working mode of the in-vehicle unit 7 through Python scripts. This design not only improves the scalability and automation of the system but also allows debuggers and developers to customize the control logic and functions according to needs. In addition, as a widely used programming language, Python has rich resources and community support, which further improves the development and maintenance efficiency of the system.
