Fig. 1 is a flowchart of a state identification method of an on-vehicle dc-dc converter according to an embodiment of the present invention.
It should be noted that the main execution body of the method for identifying the state of the on-Vehicle dc-dc converter according to the embodiment of the present invention is a controller of a Vehicle, and the controller of the Vehicle may be a Vehicle Control Unit VCU (Vehicle Control Unit), or may be a controller separately provided, and is not limited herein.
As shown in fig. 1, a method for identifying a state of a vehicle-mounted dc-dc converter according to an embodiment of the present invention includes the steps of:
and S101, acquiring the working current and voltage of the storage battery.
For example, the working current of the storage battery can be acquired in real time through a current sensor arranged at the positive end or the negative end of the storage battery; the voltage of the storage battery is collected in real time through voltage sensors arranged at the positive end and the negative end of the storage battery. And the battery manager is connected with the current sensor and the voltage sensor of the storage battery so as to acquire the working current and voltage of the storage battery in real time.
The Controller of the vehicle is connected with the battery manager through a Local Interconnect Network (LIN) bus or a Controller Area Network (CAN) bus, so that the Controller of the vehicle CAN acquire the working current and voltage of the storage battery in real time through the LIN bus or the CAN bus.
And S102, acquiring the state of an enabling end of the vehicle-mounted direct current-direct current converter.
The enabling end state of the vehicle-mounted direct current-direct current converter can be working or non-working.
The controller of the vehicle is connected with the vehicle-mounted DC-DC converter, for example, at least connected with the enabling end of the vehicle-mounted DC-DC converter, so as to obtain the enabling state of the vehicle-mounted DC-DC converter.
And S103, identifying the state of the vehicle-mounted direct current-direct current converter according to the working current and voltage of the storage battery and the state of the enabling end of the vehicle-mounted direct current-direct current converter.
For example, when the enable terminal of the on-vehicle dc-dc converter is inactive, the controller of the vehicle recognizes that the on-vehicle dc-dc converter is inactive; when the state of the enabling end of the vehicle-mounted direct current-direct current converter is working, if the voltage of the storage battery is reduced and continuously reduced, and the storage battery is continuously discharged to the outside, the state of the vehicle-mounted direct current-direct current converter is identified as abnormal.
Therefore, the state identification method of the vehicle-mounted direct current-to-direct current converter provided by the embodiment of the invention can be used for identifying the state of the vehicle-mounted direct current-to-direct current converter in advance before the vehicle does not report the fault, so that a driver is prevented from continuing driving the vehicle when the vehicle-mounted direct current-to-direct current converter is abnormal, the driving safety is improved, the probability of damage of a storage battery is reduced, and the user experience is improved.
Fig. 2 is a flowchart of a state identification method of a vehicle-mounted dc-dc converter according to an embodiment of the present invention.
As shown in fig. 2, the method for identifying the state of the on-vehicle dc-dc converter according to the embodiment of the present invention includes the following steps:
s201, obtaining the working current and voltage of the storage battery.

It should be noted that, the contents of steps S201 and S202 in the embodiment of the present invention please refer to steps S101 and S102 in the above embodiment.
And S203, calculating the average current of the storage battery according to the working current of the storage battery.
And S204, identifying the state of the vehicle-mounted direct current-direct current converter according to the average current and voltage of the storage battery and the state of the enabling end of the vehicle-mounted direct current-direct current converter.
Since the operating current of the battery may be close to 0 when the battery is fully charged or when power is supplied to a large load, the controller of the vehicle calculates the average current of the battery after acquiring the operating current of the battery in order to improve the determination of the state of identifying the on-vehicle dc-dc converter.
When the state of an enabling end of the vehicle-mounted direct current-direct current converter is non-working, a controller of the vehicle identifies that the state of the vehicle-mounted direct current-direct current converter is non-working; when the state of the enabling end of the vehicle-mounted direct current-direct current converter is working, if the voltage of the storage battery is reduced and continuously reduced, and the working current of the storage battery is larger than a set current (the set current can be set according to actual conditions), the state of the vehicle-mounted direct current-direct current converter is identified as abnormal.
And S205, when the state of the vehicle-mounted DC-DC converter is abnormal, generating vehicle-mounted DC-DC abnormal information.
And S206, sending the vehicle-mounted direct current to direct current abnormal information to the terminal.
For example, when recognizing that the state of the on-vehicle dc-dc converter is abnormal, the controller of the vehicle generates on-vehicle dc-dc abnormal information and transmits the on-vehicle dc-dc abnormal information to a terminal (such as a mobile phone) to remind a driver of the abnormality of the current on-vehicle dc-dc converter.
As another example, a driver's terminal (e.g., a mobile phone) downloads a vehicle-related APP (Application). When the controller of the vehicle recognizes that the state of the vehicle-mounted direct current-to-direct current converter is abnormal, vehicle-mounted direct current-to-direct current abnormal information is generated, the vehicle-mounted direct current-to-direct current abnormal information is sent to the terminal APP, and then the vehicle-mounted direct current-to-direct current abnormal information is pushed to after-sales personnel through the terminal APP, so that the after-sales personnel can be timely reminded to immediately analyze the fault generation reason and actively contact a vehicle owner.
Therefore, the state identification method of the vehicle-mounted DC-DC converter provided by the embodiment of the invention can be used for identifying and diagnosing the vehicle possibly with the potential risk of the abnormality of the DC-DC converter in advance before the vehicle does not report the fault, and the potential risk is avoided under the condition that a user uses the vehicle without being influenced. Even when the direct current-direct current converter fails or other failures caused by the fact that the direct current-direct current converter does not work occur, after-sales personnel can obtain information in time, active contact with a vehicle owner can be achieved, user worry is greatly reduced, user experience is improved, and brand value is improved.
In order not to increase the workload of the vehicle control unit VCU or add an additional controller, the execution subject of the state identification method of the vehicle-mounted dc-dc converter according to the embodiment of the present invention may also be a TSP (Telematics Service Provider) platform. For example, state identification logic for an on-board dc-dc converter may be added to the TSP platform. That is, the TSP platform is used as the main execution body of the state recognition method for the in-vehicle dc-dc converter according to the embodiment of the present invention.
Fig. 3 is a schematic diagram of a state recognition system of an on-vehicle dc-dc converter according to an embodiment of the present invention.
As shown in fig. 3, a state identification system for a vehicle-mounted dc-dc converter according to an embodiment of the present invention includes: the System comprises a storage Battery, a Battery manager BMS (Battery Management System), a vehicle control unit VCU (vehicle control Unit), a vehicle-mounted T-BOX (Telematics BOX), a TSP platform and a mobile phone APP.
When the TSP platform executes the state identification method of the vehicle-mounted DC-DC converter, the working current and voltage of the storage battery are acquired in real time through the battery manager, and are sent to the VCU through the LIN bus. The vehicle control unit VCU is connected to the on-board dc-dc converter, for example, at least to an enable end of the on-board dc-dc converter, so as to obtain an enable state of the on-board dc-dc converter. And the VCU of the vehicle control unit sends the working current and voltage of the storage battery and the enabling state of the vehicle-mounted DC-DC converter to the vehicle-mounted T-BOX through the CAN bus. The working current and voltage of the storage battery and the enabling state of the vehicle-mounted direct current-direct current converter are uploaded to the TSP platform at the cloud end by the vehicle-mounted T-BOX, the information uploading process does not generate cost, and other information needs to be uploaded by the vehicle-mounted T-BOX.
The TSP platform judges that the state of the vehicle-mounted DC-DC converter is abnormal if the storage battery is discharged outwards and the voltage of the storage battery is reduced and continuously reduced when the enabling state of the vehicle-mounted DC-DC converter is working. And the TSP platform immediately pushes the abnormal information of the vehicle-mounted DC-DC converter to the background server. And the background server pushes the abnormal information of the vehicle-mounted DC-DC converter to the mobile phone APP. Through cell-phone APP with the unusual information propelling movement of on-vehicle DC-DC converter to after-sales personnel, this in-process only produces the flow, can not additionally increase cost and expense, alright like this in time remind after-sales personnel backstage analysis trouble immediately to produce the reason, promote user experience and feel.
Therefore, the method for identifying the state of the vehicle-mounted DC-DC converter can be used for identifying and diagnosing the vehicle with the potential abnormal risk of the DC-DC converter in advance before the vehicle does not report the fault, avoiding the potential risk without influencing the use of the vehicle by a user, and even obtaining information in time by after-sales personnel when the fault of the DC-DC converter or other faults caused by the fact that the DC-DC converter does not work occur, so that the vehicle owner can be actively contacted, the user worry is greatly reduced, and the brand value is improved.
In summary, according to the method for identifying the state of the on-board dc-dc converter in the embodiment of the present invention, the operating current and the voltage of the battery are obtained, the state of the enable terminal of the on-board dc-dc converter is obtained, and then the state of the on-board dc-dc converter is identified according to the operating current and the voltage of the battery and the state of the enable terminal of the on-board dc-dc converter. Therefore, the method can identify the state of the vehicle-mounted direct current-direct current converter in advance before the vehicle does not report the fault, and avoids the driver from continuing to drive the vehicle when the vehicle-mounted direct current-direct current converter is abnormal, so that the driving safety is improved, the probability of damage of the storage battery is reduced, and the user experience is improved.
