Fig. 1 is a flow chart of a state identification method for a vehicle-mounted DC-to-DC converter according to an embodiment of the present disclosure.

It should be noted that the execution subject of the state recognition method of the vehicle-mounted DC-to-DC converter in the embodiment of the present disclosure is the controller of the vehicle, and the controller of the vehicle may be a vehicle controller VCU (Vehicle Control Unit, vehicle controller ), or a controller set separately, which is not limited here.

As shown in FIG. 1 , the method for identifying the state of a vehicle-mounted DC-to-DC converter according to an embodiment of the present disclosure includes steps S101-S103.

Step S101: Obtain the working current and voltage of the storage battery.

For example, the working current of the battery can be collected in real time through the current sensor installed at the positive or negative terminal of the battery; the voltage of the battery can be collected in real time through the voltage sensor installed at the positive and negative terminals of the battery. The battery manager is connected with the current sensor and voltage sensor of the battery to obtain the working current and voltage of the battery in real time.

The controller of the vehicle is connected to the battery manager through the LIN (Local Interconnect Network) bus or the CAN (Controller Area Network, Controller Area Network) bus, so that the controller of the vehicle can The bus obtains the working current and voltage of the storage battery in real time.

Step S102: Obtain the status of the enabling terminal of the vehicle-mounted DC-to-DC converter.

Wherein, the state of the enabling terminal of the vehicle-mounted DC-to-DC converter can be working or non-working.

The controller of the vehicle is connected to the vehicle-mounted DC-to-DC converter, for example, at least connected to the enabling terminal of the vehicle-mounted DC-to-DC converter, so as to obtain the enabling state of the vehicle-mounted DC-to-DC converter.

Step S103: Identify the state of the vehicle-mounted DC-to-DC converter according to the working current and voltage of the battery and the state of the enabling terminal of the vehicle-mounted DC-to-DC converter.

For example, the controller of the vehicle recognizes that the state of the vehicle-mounted DC-to-DC converter is not working when the state of the enabling terminal of the vehicle-mounted DC-DC converter is non-working; based on the state of the enabling terminal of the vehicle-mounted DC-to-DC converter as work, in response to the voltage drop of the battery and continues to drop, and the battery continues to discharge externally, it is recognized that the state of the vehicle-mounted DC-to-DC converter is abnormal.

Step S205: Based on the fact that the state of the vehicle-mounted DC-to-DC converter is abnormal, generate vehicle-mounted DC-to-DC abnormality information.

Step S206: Sending abnormality information of the vehicle-mounted DC converter to the terminal.

For example, when the controller of the vehicle recognizes that the state of the vehicle-mounted DC-to-DC converter is abnormal, it generates vehicle-mounted DC-to-DC abnormality information, and sends the vehicle-mounted DC-to-DC abnormality information to a terminal (such as a mobile phone) to remind the driver Pay attention to the abnormality of the current vehicle-mounted DC-to-DC converter.

In another example, a vehicle-related APP (Application, application program) is downloaded on the driver's terminal (such as a mobile phone). When the controller of the vehicle recognizes that the state of the vehicle-mounted DC-to-DC converter is abnormal, it generates vehicle-mounted DC-to-DC abnormality information, and sends the vehicle-mounted DC-to-DC abnormality information to the terminal APP, and then pushes it to the after-sales personnel through the terminal APP , so that the after-sales personnel can be reminded in time to analyze the cause of the failure immediately and contact the owner proactively.

Therefore, the state identification method of the vehicle-mounted DC-to-DC converter in the embodiment of the present disclosure can identify in advance the vehicle that may have a potential risk of DC-to-DC converter abnormality in advance before the vehicle reports a fault, and diagnose the fault in advance.

When the TSP platform executes the state recognition method of the vehicle-mounted DC-to-DC converter of the embodiment of the present disclosure, the battery manager obtains the working current and voltage of the battery in real time, and passes the working current and voltage of the battery through the LIN bus Send it to the vehicle controller VCU. The vehicle controller VCU is connected to the vehicle-mounted DC-to-DC converter, for example, at least connected to the enabling terminal of the vehicle-mounted DC-to-DC converter, so as to obtain the enabling state of the vehicle-mounted DC-to-DC converter. The vehicle controller VCU sends the working current and voltage of the battery and the enabling status of the on-board DC-to-DC converter to the on-board T-BOX through the CAN bus. The on-board T-BOX uploads the working current and voltage of the battery and the enabling status of the on-board DC-to-DC converter to the TSP platform in the cloud. The process of uploading information does not generate fees because the on-board T-BOX itself needs to upload other information.

The TSP platform judges that the enabled state of the vehicle-mounted DC-to-DC converter is working. In response to the external discharge of the battery, and the voltage of the battery decreases and continues to decrease, it is confirmed that the state of the vehicle-mounted DC-to-DC converter is abnormal. The TSP platform immediately pushes the abnormality information of the vehicle-mounted DC-to-DC converter to the background server. The background server pushes the abnormality information of the vehicle-mounted DC-to-DC converter to the mobile phone APP. Push the abnormal information of the vehicle-mounted DC-to-DC converter to the after-sales personnel through the mobile phone APP. In this process, only traffic is generated, and no additional costs and expenses will be added. In this way, the after-sales personnel can be promptly reminded to analyze the cause of the fault in the background and improve user experience. feel.

Therefore, the state identification method of the vehicle-mounted DC-to-DC converter in the embodiment of the present disclosure can solve the problem of early identification and fault diagnosis of vehicles that may have a potential risk of DC-to-DC converter abnormality before the vehicle reports a fault. Under the conditions that affect the user's use of the vehicle, potential risks are avoided. Even when there is a DC-to-DC converter failure or other failures caused by the DC-to-DC converter not working, the after-sales personnel can get the information in time and can actively contact the owner. Reduce user concerns and enhance brand value.
