Problems solved by technology

[0002] When the user uses the vehicle, the battery power of the vehicle will drop. The main reasons for the power drop of the vehicle battery are: the vehicle has not been used for a long time; there is a problem with the components in the vehicle, which makes the vehicle unable to sleep; the vehicle battery is damaged, etc.
However, the user cannot detect the power loss of the vehicle battery. Once the vehicle fails to start due to power loss, it can only be repaired by maintenance personnel.

Embodiment 1

[0044] figure 1 It is a flow chart of a method for detecting vehicle power loss provided by Embodiment 1 of the present invention.

[0045] refer to figure 1 , when the battery runs out of power, since the user does not have detection equipment to detect it, the state of the power loss cannot be known. Therefore, in this embodiment, the Internet of Vehicles technology is used to detect the battery voltage based on the vehicle communication module, and the battery voltage is compared with the preset voltage. Comparison, so as to determine the state of the battery voltage, and send the state of the battery voltage to the TSP platform, and the TSP platform then sends it to the user terminal. Avoid unnecessary damage.

[0046] In this embodiment, the execution subject is the vehicle communication module T-BOX, and the method includes the following steps:

[0047] Step S101, monitoring battery voltage;

[0048] Step S102, judging whether the battery voltage is greater than the ...

Embodiment 2

[0060] figure 2 It is a signaling diagram of the vehicle power loss detection method provided by Embodiment 2 of the present invention.

[0061] refer to figure 2 , the method includes the following steps:

[0062] Step S201, monitoring battery voltage;

[0063] Step S202, judging whether the battery voltage is greater than the first preset voltage; if the battery voltage is less than the first preset voltage, then judging whether the battery voltage is greater than the second preset voltage and less than the first preset voltage, and the second preset voltage is less than the first preset voltage A preset voltage; if the battery voltage is greater than the first preset voltage, proceed to step S201;

[0064] Step S203, if the voltage of the storage battery is greater than the second preset voltage and lower than the first preset voltage, then judge whether the voltage of the storage battery satisfies the power-deficiency condition;

[0065] Step S204, if the voltage of ...

Embodiment 3

Abstract

The invention provides a method and a device for detecting the power loss of a vehicle. The method comprises steps of: monitoring the voltage of a storage battery; determining whether the voltage of the storage battery is greater than a first preset voltage or not; determining whether the voltage of the storage battery is greater than a second preset voltage and less than the first preset voltageif the voltage of the storage battery is less than the first preset voltage; determining whether the voltage of the storage battery meets a power loss condition or not if the voltage of the storage battery is greater than the second preset voltage and less than the first preset voltage; sending prompt information to a TSP (Telematics Service Provider) platform if the condition is met, so that theTSP platform sends the prompt information to a user terminal; sending vehicle restart information to the TSP platform if the condition is not met, so that the TSP platform sends the vehicle restart information to the user terminal; and the power loss condition is that the voltage of the storage battery decreases a third preset voltage in a preset time period. According to the method and the devicefor detecting power loss of vehicle, the voltage of the storage battery is detected through a vehicle-mounted communication module, and the user is prompted about the power loss condition of the storage battery through the user terminal, so that the user can take corresponding measures in time, and the efficiency is improved.
