FIG. 1 is a flow chart of a data processing method according to an embodiment of the present invention, as shown in FIG. 1, the method includes the steps of:
step S102, acquiring state data of the vehicle in the charging process.
In the technical solution provided in the above step S102 of the present invention, the state data of the vehicle may be obtained when the vehicle is in a charging process, where the state data may be state data of each component in the vehicle, for example, may be a connection state, a closed state, etc. between each component, and may be used to represent a state of the vehicle, for example, a charging state and a non-charging state. The state of charge may include a charge heating state and a normal state of charge. The charge heating state may include a heat-before-charge mode and a charge-while-heat mode, which are only exemplified herein, without specific limitation to state data and charge state.
Alternatively, the status of various components of the vehicle during the charging process may be obtained to determine status data of the vehicle during the charging process.
For example, during the charging process of the vehicle, the battery temperature of a battery management component (Battery Management System, abbreviated as BMS) in the vehicle may be detected, and whether the battery temperature is within a certain temperature range may be determined, for example, whether the battery temperature is within a range of-10 ℃ to 10 ℃, if so, the charging-while-heating mode of the vehicle in the charging heating state may be determined, and the battery temperature of the battery management component may be obtained, thereby obtaining state data during the charging-while-heating process of the vehicle. And whether the temperature of the battery is less than or equal to minus 25 ℃ can be determined, if so, the temperature of the battery can be indicated to be too low, and in order to ensure the performance of the battery, the battery can be heated and then charged, so that a heating-before-charging mode of the vehicle in a charging heating state can be determined, the temperature of the battery management component can be obtained, and the state data of the vehicle in a heating process after the vehicle is charged can be obtained.

In the related art, the mechanical structure and the assembly structure of the whole vehicle control assembly can be tested, however, the electronic and electric functions of the vehicle cannot be tested and judged, and therefore, there is a technical problem that the electronic and electric performance in the vehicle cannot be determined. In the embodiment of the invention, the environment required by data interaction among the components of the vehicle in the charging process can be simulated, and the simulation data can be obtained based on the simulation, so that whether the electronic and electric functions of the control components in the vehicle reach expectations can be intuitively determined based on the simulation data, and further the technical effect of clearly determining the electronic and electric performances of the control components is realized.
It should be noted that, as long as the line of the vehicle is simulated based on the state data of the vehicle during the charging process of the vehicle, the process and the method for obtaining the simulated data are all within the protection scope of the embodiment of the present invention.
And step S106, testing the control assembly in the vehicle based on the simulation data to obtain a test result, wherein the test result is used for representing the electronic and electric functions of the control assembly.
In the technical solution of the above step S106 of the present invention, after the simulation of the state data of the vehicle is performed to obtain the simulation data, the control component in the line of the vehicle may be tested based on the obtained simulation data to obtain the test result, where the test result may be output data of the control component, may be used to characterize the electronic and electrical functions of the control component in the vehicle, and may determine that the electronic and electrical functions of the control component are normal or abnormal based on the test result. The control component may be a component in the vehicle for activating or shutting down various functions of the vehicle, for example, a battery management component and a whole vehicle control component (Hybrid Control Unit, abbreviated as HCU) of the vehicle, and the like. It should be noted that the present invention is merely illustrative, and the control components and the test results of the vehicle are not particularly limited.
Optionally, the simulation test software can detect simulation data of the vehicle in real time, the simulation data are transmitted to the simulation test software, the control component is tested, and whether the electronic and electric functions of the control component reach the expected effect can be determined. It should be noted that the present invention is merely illustrative, and the apparatus and method for testing the control assembly are not particularly limited.
For example, in a vehicle charging process, state data of a battery management component in a vehicle may be obtained, for example, a battery temperature of the battery management component is 8 ℃, which may indicate that the vehicle is in a charging and heating mode at this time, a line of the vehicle may be simulated based on the state data at this time, a simulation circuit may be obtained, a control component in the line may be tested based on the state data in the simulation circuit, and a test result may be obtained, so that an electronic and electrical performance of the control component may be determined based on the test result, where a relay in the battery management component may be a main negative relay.
In the embodiment of the invention, the circuit of the vehicle is simulated based on the state data to obtain the simulation circuit, and the control component of the vehicle is tested in the simulation circuit, so that the electronic and electric functions of the control component of the vehicle are determined, and the technical effect of determining the electronic and electric performance of the control component in the vehicle is realized.
Step S102 to step S106 are performed to obtain state data of the vehicle in the charging process; based on the state data, carrying out simulation on a line of the vehicle in the charging process to obtain simulation data; and testing the control assembly in the vehicle based on the simulation data to obtain a test result, wherein the test result is used for representing the electronic and electric functions of the control assembly. That is, the embodiment of the invention can obtain the simulation data by performing simulation on the state data acquired in the vehicle charging process, can test the control component based on the simulation data, and can obtain the test result of the control component by the simulation test, thereby determining whether the electronic and electric functions of the control component can achieve the expected effect, further solving the technical problem that the electronic and electric performances of the control component in the vehicle cannot be determined, and realizing the technical effect that the electronic and electric performances of the control component in the vehicle can be determined.
The above-described method of this embodiment is further described below.
As an optional embodiment, step S102, acquiring a power-on signal; in response to the power-up signal, control data for the control component is determined, wherein the control data includes at least one of: control data of battery temperature of a battery management component in the control component, control data of a whole vehicle control component in the control component and control data of a charging interface state in a vehicle; parameters of the control component are modified based on the control data.
In this embodiment, a power-ON signal of the vehicle may be acquired, control data of a control component in the vehicle may be determined, and parameters of the corresponding control component may be modified based ON the control data, where the power-ON signal may be information for powering up (IG-ON) a system performing a simulation test. The control data can be used for controlling the obtained simulation circuit to test the control component in the charging state; may include at least one of: control data of battery temperature of the battery management assembly, control data of the whole vehicle control assembly, control data of the state of a charging interface in the vehicle and the like. The charging interface state may be a dc connection state or an ac connection state.
Optionally, after the power-on signal of the vehicle is obtained, control data of the control component may be set, and based on the set control data, parameters of the corresponding control component may be modified, for example, a heating interval of a battery temperature may be set, a temperature value of a charging seat of the vehicle may be set, and an electrical interface state may be a direct current connection or an alternating current connection. Parameters of the corresponding control components can be modified based on the control data of the three control components.
For example, after the power-on signal is collected, the control data of the control component to be tested can be input by clicking the related control on the display, the input control data can be obtained, and the parameters of the control component can be modified based on the control data. It should be noted that the present invention is merely illustrative, and the process, the operation method and the apparatus for inputting the control data are not particularly limited.
As another example, since the vehicle may be determined to be in the charge-while-heating mode when the battery temperature of the battery management assembly is between-10 deg.c and 10 deg.c, the relay of the battery management assembly is closed, and the cradle temperature value is less than 100 deg.c. Thus, the battery temperature of the battery management assembly can be entered on the display between-8 ℃, the relay of the battery management assembly is closed, and the charging stand temperature value is 80 ℃. The control data can be obtained, based on the control data, a circuit of the vehicle in a charging and heating mode can be simulated to obtain a simulated circuit, parameters of a relay of a battery management component, parameters of a battery temperature, parameters of a charging seat temperature and the like in the simulated circuit can be modified based on the control data, for example, the charging seat temperature value of the whole vehicle control component can be controlled to be smaller than 100 ℃, the heating request signal value of the whole vehicle control component can be modified to have a request, the data can be transmitted to the battery management component, and the battery temperature of the battery management component can be modified to be-8 ℃. Based on the parameters of each modified component, the control component of the vehicle can be tested in the simulation circuit in the charging and heating process to obtain a test result, so that the electronic and electrical performance of the control component in the charging and heating process can be determined.
Optionally, when the system for simulating and testing is electrified, an electrified signal of the vehicle can be obtained, after the electrification, faults stored in the vehicle can be cleared, faults affecting electrification and charging can be avoided, and further the technical effect of improving the accuracy of the charging and heating function test of the vehicle is achieved.
It should be noted that the present invention is merely illustrative, and the control data and the parameters of the control components are not particularly limited.
As an optional embodiment, step S102, obtaining state data of the vehicle during charging includes: acquiring log data of a vehicle, wherein the log data are used for representing the working states of all components in the vehicle; status data is determined based on the log data.
In this embodiment, during a vehicle charging process, log data of the vehicle may be obtained, and state data of the vehicle may be determined based on the log data, wherein the log data may be used to characterize the operating states of various components in the vehicle. The various components may include control components and other components, where the other components may include components such as power distribution units (Power Distribution Unit, abbreviated as PDUs), programmable power supplies, signal conditioning power supplies, resistor emulation boards, input/output (I/O) wiring layers, fault injection boards, and emulation boards. It should be noted that the present invention is merely illustrative, and the components are not particularly limited.
Alternatively, the operating states of all the components in the vehicle at each moment are determined, and may be stored in Log data (Log) of the vehicle, and the state data of each component in the vehicle during a period of time may be determined by recording and analyzing the Log data, for example, log data during the period of time may be extracted and analyzed.
As an alternative embodiment, step S102, determining status data based on log data, includes: and responding to the log data that the main negative relay of the battery management assembly in the control assembly is closed, the log data that the low-voltage power supply in the vehicle is in a working state, the log data that the heater in the vehicle is in an output state, and determining state data for representing that the vehicle is in a charging heating state.
In this embodiment, the obtained log data may be analyzed, when the main negative relay of the battery management assembly is closed, the voltage power supply in the vehicle is in a working state, and the heater in the vehicle is in an output state, it may be determined that the state data of the vehicle is a charging heating state, where the low voltage power supply may be a Direct Current-Direct Current (DC-DC) power supply. The heater may be a water pump (Positive Temperature Coefficient, abbreviated PTC) with a thermistor, i.e., a water pump PTC. It should be noted that the low voltage power supply and the heater are not particularly limited by the examples.
Optionally, when log data of the vehicle is recorded, the working states of the components in the log data of a period of time may be analyzed to determine the working states of the components when the vehicle is in a charging process, so as to obtain the state data of the components in the charging process.
For example, the logged log data of a period of time may be analyzed, and when it is determined that the battery is in the charging and heating state, the operating state of the main negative relay of the battery management assembly is in the closed state, the operating state of the low-voltage power supply of the vehicle is in the operating state, and the operating state of the heater of the vehicle is in the output state, so that the data may be determined as state data when the battery is in the charging and heating state.
For another example, when the operating state of the main negative relay of the battery management assembly is in an off state or the low voltage power supply of the vehicle is in an inactive state or the heater of the vehicle is not in an active state, it may be determined that the battery is in a normal charge state.
As an alternative example, when the main negative relay of the battery management component is in a closed state, it can be stated that the vehicle starts to charge at this time, and the whole vehicle control component can be controlled to send a signal for starting to charge to the dc-dc conversion power supply, and the power supply can be controlled to operate at this time; the whole vehicle control component can be controlled to transmit power for driving the water pump PTC to the water pump PTC in an output state, the water pump PTC can be controlled to be in the output state, and the vehicle can be described as being in a charging and heating state based on the fact that the corresponding component in the vehicle is in the working state; in the rest of the cases, it may be stated that the vehicle is not in the charge heating state.
As an optional embodiment, step S104, performing simulation on the line of the vehicle during the charging process based on the state data to obtain simulation data, includes: and responding to the state data to represent that the vehicle is in a charging heating state, and carrying out simulation on a line of the vehicle in a charging process based on the log data to obtain simulation data.
In this embodiment, log data of the vehicle in the charging process may be obtained, when the state data is used to characterize the vehicle in the charging heating state, log data in the charging heating state may be obtained, a transmission process of the vehicle in the charging heating process may be determined based on the log data, and a line of the vehicle in the charging heating process may be simulated based on the log data, so as to obtain simulated data.
Optionally, when the vehicle is in a charging and heating state, log data of the vehicle in a time period corresponding to the state data may be extracted, and data transmission among all components in a line of the vehicle may be simulated based on the log data, so as to obtain simulated data of the vehicle in the charging and heating state.
For example, when the vehicle is in a charging and heating state, log data of the vehicle may be obtained, if the battery temperature of the battery management component is-8 ℃ and the relay of the battery management component is closed and the temperature value of the charging seat is 80 ℃ in the obtained log data of the vehicle, it may be explained that the vehicle is in a charging and heating mode at this time, simulation may be performed on related components (such as a whole vehicle control component and a battery management component) in a line of the vehicle based on the log data, and the related components in the line of the vehicle may be controlled based on the log data, so as to obtain simulation data.
As an optional embodiment, step S106, testing the control component in the vehicle based on the simulation data to obtain a test result, includes: testing the control assembly based on the simulation data and the log data, and determining a response result of the battery management assembly in the control assembly and a response result of the whole vehicle control assembly in the control assembly; based on the response result, a test result of the control component is obtained.
In this embodiment, the control components in the vehicle may be tested based on the simulation data, the log data, and the like, the respective response results of the battery management component and the whole vehicle control component in the control components may be determined, and the test result may be determined based on the response results of the control components, where the response results may include the response results of the whole vehicle control component and the response results of the battery management component, may be state data or output data or signals of the whole vehicle controller or the battery management component after the simulation, for example, may be connection states between the components, and closed or open states of the components, and the like, and may be used to characterize the state of the vehicle after the simulation.
Optionally, simulation test software can be deployed on the vehicle, state data and log data of the vehicle in the charging process can be monitored in real time through the software, when the vehicle is in a charging heating state, the software can be controlled to extract log data of a corresponding time period, and a circuit of the vehicle is simulated to obtain a simulation circuit. The simulation circuit can test the control of the corresponding control component based on the log data, can determine the response result obtained by the control components such as the battery management component, the whole vehicle control component and the like based on the control, and can determine whether the electronic and electric functions of the control components in the vehicle can reach expectations based on the response result.
For example, when the vehicle is in a charging and heating state, the simulation test software may be controlled to extract log data of the vehicle. Since the battery temperature of the battery management assembly is-30 deg.c, the relay of the battery management assembly is closed and the charging stand temperature value is 50 deg.c in the log data of the vehicle, it can be explained that the vehicle is in the charge-before-heat mode at this time. The log data can be obtained, and the line of the vehicle is simulated based on the log data to obtain a simulation circuit.
