DETAILED DESCRIPTION

[0019] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0020] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present disclosure should have the common meanings understood by those skilled in the art to which the present disclosure belongs.

[0021] According to an embodiment of the present disclosure, an embodiment of a vehicle battery fault detection method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0022] In this embodiment, a vehicle battery fault detection method is provided. Figure 1 is a flow chart of a vehicle battery fault detection method according to an embodiment of the present disclosure, such as Figure 1 As shown, the process includes the following steps: Step S101, when the battery voltage is detected to be less than a preset voltage threshold during the vehicle startup process, the engine speed of the vehicle and the number of consecutive startups are obtained.

[0023] The preset voltage threshold can be set according to actual conditions and is not specifically limited here.

[0024] In the disclosed embodiment, when the vehicle is started, the engine is driven while monitoring the changes in the engine speed and battery voltage; when the engine speed is greater than or equal to the preset speed threshold, it can be determined that the current battery voltage of the vehicle has the ability to drive the engine to rotate, and the number of consecutive starts of the vehicle is increased by one (not cleared when the power is off for a short time), which can be achieved through a counter. Among them, the preset speed threshold can be set according to actual conditions and is not specifically limited here.

[0025] Step S102, determining the fault cause of the battery voltage of the vehicle being less than a preset voltage threshold according to the engine speed and the number of consecutive starts.

[0026] In some specific embodiments, the above step S102 includes steps S1021 to S1023: Step S1021, if the engine speed is greater than a preset speed threshold, and the number of consecutive starts is greater than a preset number threshold, it is determined that the fault cause of the vehicle battery voltage being less than the preset voltage threshold is that the vehicle is started multiple times in a row.

[0027] Step S1022: If the engine speed is greater than the preset speed threshold, and the number of consecutive starts is less than or equal to the preset number threshold, it is determined that the fault cause of the battery voltage of the vehicle being less than the preset voltage threshold is insufficient battery power.

[0028] Step S1023: If the engine speed is less than or equal to the preset speed threshold, it is determined that the fault cause of the battery voltage of the vehicle being less than the preset voltage threshold is insufficient battery power.

[0029] In some specific embodiments, the method further comprises: Step S1024, during the vehicle startup process, if it is detected that the battery voltage of the vehicle is greater than or equal to the preset voltage threshold, and the engine speed is less than or equal to the preset speed threshold, it is determined that the engine is faulty.

[0030] In the above steps S1021 to S1024, For example Figure 2 As shown: during the vehicle startup process, if it is detected that the engine speed is less than or equal to the preset speed threshold, and the battery voltage is less than the preset voltage threshold, it is determined that the vehicle battery has a low voltage fault, and the user can be reminded to charge; conversely, if it is detected that the engine speed is less than or equal to the preset speed threshold, and the battery voltage is greater than or equal to the preset voltage threshold, it is determined that the engine drive is abnormal; If the engine speed is greater than the preset speed threshold, but the battery voltage is less than the preset voltage threshold (indicating that the vehicle battery has a low voltage fault), the number of consecutive starts of the current vehicle needs to be considered (which can be determined by a counter). If the number of consecutive starts is greater than the preset number threshold, it is determined that the low voltage fault of the current vehicle battery is due to the temporary weakening of the starting ability due to multiple consecutive starts. The battery voltage can be restored, and there is no need to send a low battery voltage fault prompt message to the driver. The driver can be reminded to start again after a period of time; On the contrary, if the engine speed is greater than the preset speed threshold, the battery voltage is less than the preset voltage threshold (indicating that the vehicle battery has a low voltage fault), and the number of consecutive starts of the vehicle is less than or equal to the preset number threshold, it can be determined that the starting ability is weak and the battery voltage is actually low, and a low battery voltage fault is reported to remind the driver to charge.

[0031] Step S103: generating fault prompt information according to the fault cause.

[0032] Among them, the fault causes that cause the battery voltage to be less than the preset voltage threshold during vehicle startup include but are not limited to: starting the vehicle multiple times in a row and insufficient battery power.

[0033] In some specific embodiments, the above step S103 includes steps S1031 to S1033: Step S1031, when the fault cause is starting the vehicle multiple times in succession, a first prompt message is generated and sent to the driver.

[0034] Step S1031: When the fault cause is insufficient battery power, a second prompt message is generated and sent to the driver.

[0035] Step S1031: When the fault cause is an engine fault, a third prompt message is generated and sent to the driver.

[0036] In the disclosed embodiment, if it is determined that the fault cause causing the battery voltage to be less than the preset voltage threshold during vehicle starting is that the vehicle is started multiple times in succession, a first prompt message is sent to the outside to remind the driver to start the vehicle again after a period of time; if it is determined that the fault cause causing the battery voltage to be less than the preset voltage threshold during vehicle starting is that the battery power is insufficient, a second prompt message is sent to the outside to remind the driver to charge the vehicle; if an engine fault is detected, a third prompt message is sent to the outside to remind the driver that the engine driving is abnormal.

[0037] The existing battery voltage detection method does not distinguish the engine working conditions for judgment, and it is very easy to misreport the low battery voltage after the starter has worked for many times. The disclosed embodiment can distinguish the working conditions by collecting and judging the engine speed and battery voltage, and better judge the low battery voltage, thereby reducing the failure rate and increasing the accuracy of low battery voltage judgment.
