Embodiment 1

[0067] Therefore, when the voice service and data service of the vehicle terminal can run independently, such as figure 2 As shown, the process of power supply conversion for vehicle-mounted terminals based on the power supply conversion method disclosed in this application includes:

[0068] S10. In response to detecting that the main battery of the vehicle does not meet the preset condition, acquire the real-time voltage of the backup battery of the vehicle through the first preset sensor and the real-time temperature of the backup battery through the second preset sensor;

[0069] Among them, the main battery can supply power to the vehicle terminal and other vehicle equipment under normal circumstances. When the voltage of the main battery is too low or otherwise unable to supply power, the vehicle-mounted terminal will receive the KL30 OFF signal indicating that the main battery cannot supply power, and automatically activate the backup battery for power supply. The veh...

Embodiment 2

[0112] Corresponding to the above-mentioned embodiment, the present application provides a power supply conversion method. In this embodiment, for the same or similar content as the above-mentioned Embodiment 1, reference may be made to the introduction above, and details will not be repeated hereafter. Such as image 3 As shown, the power supply conversion method includes:

[0113] 310. In response to detecting that the main battery of the vehicle does not meet the preset condition, acquire the real-time voltage of the backup battery of the vehicle through the first preset sensor, and the backup battery is used to supply power to the vehicle terminal of the vehicle;

[0114] 320. Determine a first candidate working module that needs power supply among the one or more working modules according to the current working status of the one or more working modules and / or a user's trigger operation on the one or more working modules, the One or more working modules belong to the vehi...

Embodiment 3

[0140] Corresponding to all the above-mentioned embodiments, the present application provides a power supply conversion device. In this embodiment, the content that is the same as or similar to the above-mentioned Embodiment 1 and Embodiment 2 can be referred to above, and will not be repeated hereafter. Such as Figure 4 As shown, the power conversion device includes:

[0141] The acquiring module 410 is configured to acquire the real-time voltage of the backup battery of the vehicle through the first preset sensor in response to detecting that the main battery of the vehicle does not satisfy the preset condition, and the backup battery is used to supply the vehicle-mounted terminal of the vehicle powered by;

[0142] A judging module 420, configured to determine a first candidate job requiring power supply among the one or more working modules according to the current working status of the one or more working modules and / or a user's trigger operation on the one or more work...

Abstract

The present application discloses a power supply conversion method, which includes obtaining the real-time voltage of the backup battery of the vehicle through a sensor in response to detecting that the main battery of the vehicle does not meet the preset conditions; according to the current working state of one or more working modules and / or The user's trigger operation on one or more working modules determines the first candidate working module that needs power supply; according to the corresponding relationship between the voltage and the working module that can supply the first power supply, determine the second candidate working module that can be powered by the first power supply corresponding to the real-time voltage The first working module that can supply power includes at least a trigger circuit module for an emergency call service; the target module to be powered is determined according to the first candidate working module and the second candidate working module, and the first power supply is provided to the target module to be powered by a backup battery. Make the target module to be powered perform the corresponding service, avoiding the problem that the backup battery is quickly exhausted due to the power supply to the working module and cannot support a longer power supply time for the emergency call service.

Description

technical field [0001] The present application relates to the field of vehicle control, in particular to a power supply conversion method and device. Background technique [0002] In order to improve the driving experience of users, many vehicles are equipped with TBOX, that is, vehicle-mounted terminals. TBOX has multiple functions such as data collection, remote diagnosis, and remote control, and can provide driving assistance and safety guarantee for users' driving. Emergency call service is an indispensable basic function of TBOX. It can be automatically or manually triggered by the user to send help information to the preset alarm platform when the vehicle is in an emergency, which can improve the user's ability to get help in an emergency Efficiency guarantees the driving safety of users. [0003] However, with the advancement of technology, more and more TBOX has added functions such as 5G and V2X. These functions have the need to push data to the background, and t...
