Example 1

According to an embodiment of the present invention, there is provided an embodiment of a data processing method of a vehicle, it being noted that the steps shown in the flowcharts of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

Fig. 1 is a flowchart of a data processing method of a vehicle according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:

step S102, control data of a simulation circuit of the vehicle is obtained, wherein the simulation circuit is used for simulating a starting process or a closing process of a high-voltage system of the vehicle.

In the technical scheme provided in the step S102, control data of a simulation circuit of the vehicle can be obtained, and a starting process or a closing process of a high-voltage system of the vehicle is simulated by the simulation circuit based on the control data, wherein the simulation circuit can comprise various components of the vehicle and can be used for performing simulation on the starting or closing process of the high-voltage system of the vehicle. The control data may be used to control the status of various components in the simulated analog circuit, where the various components of the vehicle may include components such as a vehicle control component, a micro control unit, and a battery management component. It should be noted that the present invention is merely illustrative, and the components and control data of the vehicle are not particularly limited.

Alternatively, when different control data are set, the simulation circuit may be controlled to simulate a start-up or shut-down process in which the vehicle is in a high-voltage system. Therefore, in the embodiment of the invention, the simulation analog circuit is controlled by setting different control data, and the starting or closing process of the high-voltage system, the processes of collision monitoring, high-voltage insulation detection and the like of the high-voltage system can be simulated by utilizing the simulation analog circuit, so that the technical effect of determining the electronic and electric properties of the component under different processes of the high-voltage system of the vehicle is achieved.

Step S104, adjusting parameters of the simulation circuit based on the control data, and determining a control result of a control component in the adjusted simulation circuit on starting or closing a high-voltage system for driving the vehicle.

In the technical solution provided in the above step S104 of the present invention, parameters of corresponding components in the simulation circuit may be adjusted by control data, after parameter adjustment, a start process or a shutdown process of the high voltage system may be simulated by using the simulation circuit, and a control result of a control component in the simulation circuit in the simulation process may be determined, where the control component may include a vehicle control component and a battery management component (Battery Management System, abbreviated as BMS) and may be used to control the high voltage system of the vehicle to be started or shut down, and the vehicle control component may be a hybrid vehicle controller (Hybrid Control Unit, abbreviated as HCU). The control result can be used for representing states of all components in the simulation analog circuit and information transmitted among the components, for example, the micro control unit transmits high-voltage down information to the whole vehicle control component, and the main negative relay of the battery management component is opened or closed. It should be noted that the present invention is merely illustrative, and the control components and the control results of the vehicle are not particularly limited.

Optionally, components required in the starting or closing process of the high-voltage system can be connected to obtain a simulation circuit of the vehicle, and in the simulation circuit of the vehicle, the set control data can be transmitted to the simulation circuit, and parameters of the corresponding components can be adjusted based on the control data.

For example, when the low-voltage power supply of the vehicle is set to perform power-down (IG-OFF) or the communication node of the battery management component is set to be lost, the fault injection board simulates a high-voltage interlocking fault, and control data such as a vehicle collision signal can be set, the shutdown process of the high-voltage system can be determined. Thus, the communication node loss of the battery management assembly may be set as the control data. The control data lost by the communication node of the battery management assembly is acquired, the control data can be input into a simulation circuit, and the simulation circuit is utilized to simulate the closing process of the high-voltage system. In the simulation process, the communication node parameters of the battery management component in the simulation circuit can be adjusted to be in a lost state based on the control data. After the parameters are adjusted, a control component in the simulation analog circuit can be controlled to start or stop the high-voltage system. After the high-voltage system is completely started or shut down, the control result of the control assembly can be determined.

Step S106, based on the control result, determining the state of the control component, wherein the state is used for representing the electronic and electrical performance of the control component.

In the technical solution of step S106 of the present invention, after the parameters in the simulation circuit are adjusted by the control data, the components in the simulation circuit may be controlled based on the adjusted parameters to obtain a control result, and based on the control result, the state of the control component may be determined, where the state of the control component may be used to characterize the electronic and electrical performance of the control component, and may include a normal state and an abnormal state.

Optionally, after the control result is obtained, the control result of the high-voltage system can be started or closed through simulation test software deployed in the simulation circuit to monitor and judge, so that the state of the control component can be determined, and whether the electronic and electrical performance of the control component reaches the expected value can be judged.

For example, the high-voltage power-down permission signal transmitted by the micro control unit to the whole vehicle controller can be recorded through the simulation test software, the states of the main positive high-voltage relay and the main negative high-voltage relay in the battery management assembly can be recorded through the simulation test software, the control result recorded in the simulation test software can be compared with a predetermined control result, and if the control result and the control result are the same, the fact that the electronic and electric states of the control assembly are normal in the process of starting or closing the high-voltage system of the vehicle can be described; conversely, the abnormal state of the electronic and electric state can be described.

In the embodiment of the invention, the control result in the simulation circuit can be analyzed and judged, so that whether the electronic and electric performance of the control component of the vehicle is normal or not can be determined, whether the electronic and electric functions of the control component meet expectations or not in the process of starting or closing the high-voltage system of the vehicle can be determined, and the technical problem that the electronic and electric performance of the control component of the vehicle in the process of starting or closing the high-voltage system can not be determined is solved.

In the embodiment of the present invention, in the steps S102 to S106, control data of a simulation circuit of a vehicle is obtained, where the simulation circuit is used to simulate a starting process or a closing process of a high-voltage system of the vehicle; adjusting parameters of the simulation circuit based on the control data, and determining a control result of a control component in the adjusted simulation circuit on starting or closing a high-voltage system for driving the vehicle; based on the control result, a state of the control component is determined, wherein the state is used to characterize the electrical and electronic performance of the control component. That is, the embodiment of the invention can carry out simulation test on the starting and closing process of the high-voltage system by setting different control data, can adjust the parameters of the components in the simulation circuit based on the control data, can control the simulation circuit to start or close the high-voltage system based on the adjusted parameters, can obtain a control result, and can determine whether the electronic and electric functions of the control components in the vehicle can achieve the purpose of expected effect based on the control result, thereby solving the technical problem that the electronic and electric performances of the control components of the vehicle can not be determined in the starting or closing process of the high-voltage system, and realizing the technical effect that the electronic and electric performances of the control components of the vehicle can be determined in the starting or closing process of the high-voltage system.

The above-described method of this embodiment is further described below.

As an alternative embodiment, step S102, obtaining control data of a simulation circuit of a vehicle includes: and acquiring an instruction control signal, and determining control data corresponding to the instruction control signal as control data of a simulation circuit, wherein the instruction control signal is used for indicating the simulation circuit to simulate the starting or closing process of a high-voltage system in the vehicle.

In this embodiment, the command control signal may be acquired, control data corresponding to the command control signal may be determined, and the control data may be used as control data of a simulation circuit, where the command control signal may be used to instruct the simulation circuit to simulate a start-up or shut-down process of a high voltage system in a vehicle.

Alternatively, when a process of starting up the high voltage system or shutting down the high voltage system is desired to be tested, an instruction control signal corresponding to the desired process may be input by clicking on an associated control on the display. The control data corresponding to the command control signal can be used as the control data of the simulation circuit, and parameters in the simulation circuit are modified based on the control data so as to complete the simulation of the process of starting or closing the high-voltage system.

For example, control data may be predetermined when the vehicle is in a state of starting the high voltage system, and when it is desired to simulate the starting state of the high voltage system, an instruction control signal to start the high voltage system may be issued by clicking a test control in the display interface. The command control signal is acquired, and control data of the high-voltage system starting corresponding to the command control signal of the high-voltage system starting can be determined, so that the process of starting the high-voltage system is simulated based on the control data.

In the embodiment of the invention, the command control signal in the state of starting or closing the high-voltage system can be preset, the command control signal corresponding to the process to be tested is obtained, and the control data corresponding to the command control signal can be determined as the control data of the simulation circuit in the process to be tested, so that the aim of rapidly testing the starting and closing process of the high-voltage system can be fulfilled.

As an optional embodiment, step S102, obtaining the command control signal, and determining the control data corresponding to the command control signal includes: responding to the instruction control signal for indicating the simulation circuit to simulate the starting process of the high-voltage system, and detecting whether collision signals exist in the simulation circuit; and determining control data corresponding to the collision signal in response to the collision signal in the simulation circuit, or determining control data corresponding to the command control signal in response to the collision signal not in the simulation circuit.

In this embodiment, it may be determined whether the command control signal is used to instruct the emulation simulation circuit to simulate the start-up process of the high voltage system, and if so, whether a collision signal exists in the emulation simulation circuit may be detected. If collision signals exist, control data corresponding to the collision signals can be determined, so that the collision monitoring process of the high-voltage system can be simulated based on the collision signals; if no collision signal exists, control data corresponding to the command control signal can be determined, so that a starting process of the high-voltage system can be simulated based on the control data, wherein the collision signal can be used for representing whether the vehicle collides or not.

Optionally, after the instruction control signal for instructing the emulation simulation circuit to simulate the start-up process of the high voltage system is acquired, control data corresponding to the instruction control signal may be determined. The corresponding high-voltage system starting process can be simulated based on the control data through the simulation circuit. In the simulation process, an air bag (Airbag) controller in the simulation circuit can be used for detecting signals sent by a sensor in the simulation circuit to determine whether collision (including front collision and rear collision) occurs, and if the collision is detected, the existence of collision signals in the simulation circuit is indicated. The control data corresponding to the collision signal can be determined to be used as the control data of the simulation circuit, so that the collision condition during starting of the high-voltage system can be detected and simulated. If no collision is detected, the control data corresponding to the command control signal at the moment can be determined as the control data of the simulation circuit, so that the process of starting the high-voltage system is simulated.

For example, when it is desired to test the collision monitoring function during the start-up of the high voltage system, by clicking the test control in the display interface, an instruction control signal for testing the collision monitoring function during the start-up of the high voltage system may be issued. For example, the sensor may be configured to emit a signal that is indicative of a collision. The control data corresponding to the command control signal can be input into a simulation circuit, and the simulation circuit is utilized to simulate the collision detection function of the starting high-voltage system. In the simulation process, parameters of the sensors in the simulation circuit may be adjusted based on the control data. Based on the adjusted parameters, signals sent by the air bag detection sensor can be controlled, so that whether collision occurs or not is determined, whether the main positive relay and the main negative relay of the battery management assembly are disconnected or not can be controlled, and whether connection signals of the main positive relay and the main negative relay of the battery management assembly are changed or not is detected. If both relays are turned off, high voltage down-charging is possible.

For another example, in the simulation process, the moment of sending the collision signal may be recorded through the test interface software in the simulation circuit, the moment of disconnecting the main positive relay and the main negative relay may be recorded, the time difference between the two moments may be determined, whether the reaction time of the collision monitoring of the high voltage system is normal may be determined through the time difference, and if the time difference is within one second, it may be indicated that the reaction time of the collision monitoring of the high voltage system is normal. The battery management component can be controlled to feed back fault (fault) information to the whole vehicle control component. At the moment of collision, the test interface software is also required to be controlled to detect whether the micro control unit monitors collision signals sent by the whole vehicle controller and disconnection signals of the two relays. At this time, the micro control unit can be controlled to trigger the active discharge function, and whether the micro control unit externally sends out an active discharge signal or not and the active discharge can be monitored through the test interface software. If the voltage value of the motor direct current bus sent by the micro control unit is lower than 60V, the active discharge of the high-voltage system is ended, the simulation of the collision monitoring function in the starting process of the high-voltage system can be described, and after the simulation is ended, data such as the control result can be stored in log data, so that the fault condition can be conveniently extracted and analyzed.

As an alternative embodiment, step S106, determining the state of the control component based on the control result, includes: determining that the state of the control component is a normal state in response to the control result being the same as a preset control result; or determining that the state of the control component is an abnormal state in response to the control result being different from the preset control result.

In this embodiment, after the control result is obtained based on the simulation circuit, it may be determined whether the control result is the same as the preset control result, and if so, it may be determined that the state of the control component is a normal state in the simulation process; if the states are different, the state of the control component in the simulation process can be determined to be abnormal.

Because the mechanical structure and the assembly structure of the whole vehicle control assembly are tested in the related art, the test and the judgment of the electronic and electric functions of the control assembly in the vehicle cannot be determined, and therefore, the technical problem that the electronic and electric performance in the vehicle cannot be determined in the starting process or the closing process of the high-voltage system exists. In the embodiment of the invention, the control result of the control component after the control related control component realizes the process can be determined in advance based on the starting or closing process of the high-voltage system to be tested, so as to obtain the preset control result. And simulating environment and control data required by information interaction between the whole vehicle control assembly and other assemblies in a simulation circuit of the vehicle, performing simulation on a starting process and a closing process of a high-voltage system of the vehicle, and obtaining an actual control result of the control assembly after the simulation. The actual control result of the control component in the vehicle can be compared with the preset control result, and whether the electronic and electric functions of the control component in the vehicle reach the expectations can be determined, so that the technical effect that the electronic and electric performances of the control component in the vehicle can be determined in the starting process or the closing process of the high-voltage system is realized.

As an optional embodiment, step S106, in response to the state of the control component being an abnormal state, obtains a change state of each component in the simulation circuit; and analyzing the change state of each component to determine abnormal components in each component.

In this embodiment, when the control result is different from the preset control result, it may be determined that the state of the control component is an abnormal state, and at this time, the change states of the components in the simulation circuit may be obtained, the change states of the components may be analyzed, and it may be determined whether the abnormal component exists in the components.

In the embodiment of the invention, the control data, the control result and the like can be stored in the Log (Log) according to the time sequence, and the troubleshooting and the solving of the component faults in the simulation circuit are facilitated by recording and analyzing the data in the Log.

For example, a log in a period of time can be extracted for analysis, the state of each component in the simulation circuit in the period of time and the information transmitted between the components can be determined, if the state of a certain component or the transmitted information is abnormal, the component can be described as an abnormal component, so that the technical effect of troubleshooting and solving the faults of the simulation circuit can be realized.

As an optional embodiment, step S104, the control data includes resistance control data, where adjusting parameters of the simulation circuit based on the control data includes: adjusting the resistance value of the insulation resistor in the simulation circuit based on the resistance control data; determining a control result of a control component in the adjusted simulation circuit comprises the following steps: and determining a control result of the battery management component in the control component and a control result of the whole vehicle control component in the control component in response to the adjusted resistance value of the insulation resistance being in the target range.

In this embodiment, the control data may include resistance control data, a process of starting or closing the high voltage system may be simulated by using a simulation circuit based on the resistance control data, a resistance of an insulation resistor in the simulation circuit may be adjusted to obtain the adjusted resistance of the insulation resistor, whether the resistance is within a target range may be determined, and if yes, a control result of the battery management assembly and a control result of the whole vehicle control assembly may be determined, where the resistance control data may be a resistance of the insulation resistor.

Alternatively, when it is desired to test the high-voltage insulation detection function, resistance value control data may be set as control data for testing the high-voltage insulation detection function. The resistance control data can be obtained, the high-voltage insulation detection process can be simulated by using the simulation circuit, the resistance of the corresponding insulation resistor can be adjusted based on the resistance control data in the high-voltage insulation detection process, and after adjustment, the whole vehicle control assembly, the battery management assembly and the like can be controlled, so that the high-voltage insulation detection is realized. And can determine the status of the control assembly and the information transmitted after the high voltage insulation detection is achieved. It should be noted that the present invention is merely illustrative, and the control data, the control method and the state of the control component for testing the high voltage insulation detection function are not particularly limited.

For example, in a simulation circuit of a vehicle, control data may be acquired, and in response to the control data being resistance control data, a process of high-voltage insulation detection may be simulated by the simulation circuit. When the resistance value of the insulation resistor is set to be 60-200 kiloohms, components in the simulation analog circuit can be controlled to activate the high-voltage insulation detection function. Therefore, the resistance value of the insulation resistance can be set to 100 kilo ohms as the resistance value control data. And acquiring the resistance control data, inputting the resistance control data into a simulation circuit, and performing simulation on the process of activating the high-voltage insulation detection function by using the simulation circuit. In this process, the resistance value of the insulation resistance in the simulation circuit can be adjusted to 100 kilo ohms based on the resistance control data. Based on the modified resistance value, whether a secondary insulation fault signal (BMS_ Insulation Warning) of the battery management component is set or not CAN be determined through test interface software, the signal CAN be sent to the whole vehicle control component through a CAN bus, when the whole vehicle control component receives the signal, the secondary insulation fault CAN be determined to occur at the moment, the signal CAN be transmitted to an observation instrument (Instrument Calibration, simply called IC) through a gateway controller, whether an alarm lamp on the observation instrument is lightened or not CAN be determined, whether a high-voltage insulation fault is displayed in a display area of the observation instrument or not CAN be determined, if the display area of the observation instrument is successfully displayed, the fault diagnosis function CAN be effectively indicated, and whether the electronic and electric performance of the control component in the simulation process is normal or not CAN be determined.

For another example, different insulation resistance values can be set repeatedly, and the alarm lamp of the monitoring observation instrument can be used as the threshold value of the resistance of the high-voltage insulation monitoring function, for example, 60-200 kiloohms. The resistance value can be set to above 300 kiloohms, whether the alarm lamp of the observation instrument disappears or not is determined, and whether the insulation alarm information on the whole vehicle control component is set to 0 or not is determined after the battery management component detects that the resistance value is recovered to be normal.

As an optional embodiment, step S104, determining, based on the control result, the state of the control component includes: and responding to the control result of the battery management assembly and the control result of the whole vehicle control assembly to send out an insulation alarm signal, and determining that the state of the control assembly is a normal state.

In this embodiment, when the control result of the battery management component and the control result of the vehicle control component are insulation alarm signals, it may be determined that the state of the control component is a normal state, where the insulation alarm signals may be insulation fault signals, and may include a primary insulation fault signal and a secondary insulation fault signal. Primary insulation faults may be used to characterize higher severity insulation faults. Secondary insulation faults may be used to characterize less severe insulation faults.

Optionally, based on the resistance control data, a process of high-voltage insulation detection is simulated by using a simulation circuit. After the simulation is finished, the control result of the battery management assembly and the control result of the whole vehicle control assembly can be obtained. The control results can be identified and judged, and whether the two control results contain the insulation alarm signal or not is determined. If so, it may be stated that the state of the control component of the vehicle is normal at this time, that is, the electronic and electrical performance of the control component is normal.

For example, in a simulation circuit of a vehicle, control data may be acquired, and in response to the control data being resistance control data, a process of high-voltage insulation detection may be simulated by the simulation circuit. When the resistance value of the insulation resistor is set below 60 kiloohms, components in the simulation analog circuit can be controlled to activate the high-voltage insulation detection function. Therefore, the resistance value of the insulation resistance can be set to 50 kilo ohms as the resistance value control data. And acquiring the resistance control data, inputting the resistance control data into a simulation circuit, and performing simulation on the process of activating the high-voltage insulation detection function by using the simulation circuit. In this process, the resistance value of the insulation resistance in the simulation circuit can be adjusted to 50 kilo ohms based on the resistance control data. Based on the modified resistance value, whether a primary insulation fault signal of the battery management component is set or not CAN be determined through test interface software, the signal CAN be sent to the whole vehicle control component through a CAN bus, after the whole vehicle control component receives the signal, the occurrence of the primary insulation fault CAN be determined, the signal CAN be transmitted to an observation instrument through a gateway controller, whether an alarm lamp on the observation instrument is lightened or not CAN be determined, whether a high-voltage insulation fault is displayed in a display area or not CAN be determined, and if the display area is successfully displayed, the fault diagnosis function CAN be effectively described. The control result of the battery management component in the control result is that a primary insulation fault signal is sent, the control result of the whole vehicle control component is that a primary insulation fault occurs, the state of the control component can be determined to be a normal state, and then the electronic and electrical performance of the control component in the simulation process can be described as normal.
