[0044] Figure 2 The figure is a schematic diagram of the structure of an active protection device for an automobile provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0046] An embodiment of the present invention provides an active protection method for an automobile. The active protection method can be executed by an active protection device for an automobile and is suitable for suppressing abnormal conditions caused by the driver's driving behavior and other reasons during the driving of the automobile. Figure 1Schematic diagram of a process flow of an active vehicle protection method provided by an embodiment of the present invention. Figure 1 , the automobile active protection method comprises the following steps:

[0047] S110: Acquire the state monitoring data of the vehicle, and determine whether the state monitoring data is abnormal.

[0048] Among them, the state monitoring data can be voltage data, current data or temperature data, and the state monitoring data can be used to indicate faults such as overtemperature, overvoltage, overcurrent, surge, etc. The state monitoring data can be collected by setting a state monitoring data collection device, such as a voltage sensor, a current sensor or a temperature sensor, at the port of the automotive electronic device such as the power supply port of the battery pack or the bus port of the control system, to collect the port voltage, port current or port temperature as the state monitoring data. Among them, the state monitoring data collection device is set on the side close to the power supply end (away from the back-stage circuit) to ensure that in the event of an abnormality, after the protection instruction is executed, the collection device can continue to collect the state monitoring data. Exemplarily, the voltage data can be but not limited to the battery voltage data or the motor voltage data in the car; the current data can be but not limited to the battery current data or the motor current data in the car; the temperature data can be but not limited to the battery temperature data or the motor temperature data in the car.

[0049] Exemplarily, the condition for determining whether the state monitoring data is abnormal may be: when the state monitoring data exceeds a preset threshold, the state monitoring data is determined to be abnormal. For example, when the surge amplitude exceeds a safety threshold, it is determined that a surge has occurred.

[0050] S120: If the status monitoring data is abnormal, a protection instruction of a corresponding level is generated according to the abnormal level of the status monitoring data, and the status monitoring data is transmitted to a main control unit of the vehicle.

[0051] Among them, when the status monitoring data is abnormal, a hierarchical protection mechanism can be formed according to the abnormal level of the status monitoring data. For the abnormal level from low to high, reminder instructions, warning instructions and direct action instructions can be generated step by step; the higher the abnormal level, the stronger the effect of the protection instruction. Outputting protection instructions in time according to abnormal data can effectively prevent the spread of faults to the subsequent circuits. At the same time, transmitting the status monitoring data to the main control unit is conducive to the main control unit to analyze the actual cause of the abnormality. In addition, the vehicle operation data and historical data are also the basis for the main control unit to analyze the cause of the abnormality.

[0052] Exemplarily, the vehicle operation data may be any data that can reflect the current operating state of the vehicle, including but not limited to: at least one of motor rotor position data, motor speed data, vehicle charging state data, acceleration data, gyroscope data, and accelerator pedal position data. The vehicle operation data may be collected by detection devices such as sensors, detection circuits, or detection software. The vehicle operation data may be used to indicate the actual driving state of the vehicle when an abnormality occurs, such as vehicle speed, whether it is turning, etc. The historical data may be data related to the abnormal state of the vehicle pre-stored in the background database. There may be multiple historical data, corresponding to various states of the vehicle. The historical data may be generated and stored during the factory test of the vehicle, or it may be continuously supplemented and updated during the driving process of the vehicle. The historical data may specifically include historical state monitoring data when an abnormality occurs in the previous driving process of the vehicle, historical vehicle operation data, and historical abnormal feature information extracted from the above-mentioned historical basic data, etc.

[0053] S130, obtaining current driving behavior data output by the main control unit; wherein the main control unit generates the current driving behavior data according to the state monitoring data, the vehicle operation data and the historical data.

[0054] Among them, the main control unit can first generate preliminary driving behavior data through the state monitoring data and the vehicle operation data; then determine whether there is behavior data matching the preliminary driving behavior data in the historical data, so as to determine the specific current driving behavior data. It is also possible to first determine whether there is basic data matching the state monitoring data and the vehicle operation data in the historical data, and then determine the specific current driving behavior data. Exemplarily, when the matching degree between the current data and the historical data exceeds the matching threshold, it can be considered that the current data matches the historical data, and the matching threshold is set, for example, between 70% and 90%. Exemplarily, the current driving behavior data can indicate the driving instructions currently executed by the vehicle.

[0055] S140: Generate a driving control instruction and / or an alarm signal according to the current driving behavior data to adjust the driving state of the vehicle and end the abnormal state of the vehicle.

[0056] The driving control instructions are used to control the vehicle to return to a normal driving state or a healthy driving state, thereby slowing down or avoiding the continued occurrence of abnormal conditions. If it is analyzed that the abnormal driving state of the vehicle is caused by the driver's bad driving habits, an alarm signal can be output to remind the driver, so that the driver can change the driving instructions (such as slowing down, etc.) according to the reminder; at the same time, a driving log and corresponding driving suggestions can be generated and provided to the driver so that the driver can correct his or her bad driving habits.

[0057] Exemplarily, when the current driving behavior data is rapid overtaking data, the driving control instruction may be a sudden acceleration limit instruction to internally control the acceleration of the car; the alarm signal may be an alarm signal corresponding to rapid overtaking to remind the driver of bad driving behavior and the need to adjust the driving behavior.

[0058] When the current driving behavior data is rapid turning data, since it also belongs to rapid acceleration behavior, the driving control instruction can still be a rapid acceleration limit instruction to internally control the acceleration of the car; the alarm signal can be an alarm signal corresponding to a rapid turn to remind the driver that he has bad driving behavior and needs to adjust his driving behavior.

[0059] In the automobile active protection method provided by the embodiment of the present invention, whether the automobile is abnormal is determined by judging whether the state monitoring data is abnormal, and the judgment process is simple and easy. When the state monitoring data is abnormal, in addition to generating a protection instruction to protect the fault in time, the state monitoring data is also transmitted to the main control unit, and the main control unit generates current driving behavior data according to the state monitoring data, the automobile operation data and the historical data; wherein the current driving behavior data characterizes the current driving state of the automobile, and the difference between the current driving state of the automobile and the normal driving state can preliminarily indicate the cause of the abnormality. According to the current driving behavior data, a driving control instruction and / or an alarm signal are generated. The driving control instruction can be directly used to correct the driving state of the vehicle, and the alarm signal can remind the driver to make a correction action to change the driving state of the vehicle. Both can reduce the generation of abnormal states from the source. In summary, the embodiment of the present invention can obtain the current driving state of the automobile according to the current driving behavior data generated by the main control unit after determining that the automobile is abnormal through the state monitoring data, and guide the automobile to self-adjust to achieve active protection.

[0060] The specific process of the main control unit generating the current driving behavior data is described below, but it is not intended to limit the present invention.

[0061] In one embodiment, optionally, the historical data includes: historical state monitoring data, historical vehicle operation data, and historical behavior data corresponding to the historical state monitoring data and the historical vehicle operation data. Then, generating current driving behavior data according to the state monitoring data, the vehicle operation data and the historical data includes:

[0062] Determine whether the status monitoring data and vehicle operation data match the historical status monitoring data and historical vehicle operation data; if so, use the historical behavior data as the current driving behavior data; if not, generate the current driving behavior data based on the status monitoring data and vehicle operation data.

[0063] Among them, when a set of status monitoring data and vehicle operation data are matched with the corresponding data in the historical data, the match is considered successful. When the match is successful, the historical behavior data can be directly used as the current driving behavior data, and there is no need to analyze the current driving behavior data based on the current data, which effectively reduces the calculation process.

[0064] In another embodiment, optionally, the historical data includes: historical behavior data. Then, the current driving behavior data is generated according to the state monitoring data, the vehicle operation data and the historical data, including:

[0065] Generate preliminary driving behavior data based on condition monitoring data and vehicle operation data.

[0066] Determine whether the preliminary driving behavior data matches the historical behavior data; if so, use the historical behavior data as the current driving behavior data; if not, use the preliminary driving behavior data as the current driving behavior data.

[0067] This configuration of the present embodiment can effectively reduce the storage space occupied by the backend database.

[0068] On the basis of the above-mentioned embodiments, optionally, the historical data also includes historical driving control instructions corresponding to the historical behavior data. Then, when the current data matches the historical data, that is, when the historical behavior data is used as the current driving behavior data, the historical driving control instructions corresponding to the historical behavior data can be directly used as the driving control instructions, thereby reducing the calculation process. If the current driving behavior data does not correspond to the historical behavior data, the driving control instructions are regenerated according to the current driving behavior data.

[0069] Based on the above embodiments, optionally, after generating the driving control instruction, the current driving behavior data and the current driving control instruction may be used to update the historical data. After generating the alarm signal, the current driving behavior data and its related data may be used to update the historical data.

[0070] On the basis of the above-mentioned embodiments, optionally, the hierarchical protection mechanism formed according to the abnormal level of the status monitoring data includes three levels of protection; according to the protection level, the protection instruction can be a reminder instruction, a warning instruction or a direct action instruction. Then, generating a corresponding level of protection instruction according to the abnormal level of the status monitoring data specifically includes: if the value of the status monitoring data is greater than the first abnormal threshold, a reminder instruction is generated; if the value of the status monitoring data is greater than the second abnormal threshold, a warning instruction is generated; if the value of the status monitoring data is greater than the third abnormal threshold, a direct action instruction is generated. Among them, the second abnormal threshold is greater than the first abnormal threshold, and the third abnormal threshold is greater than the second abnormal threshold.

[0071] On the basis of the above-mentioned embodiments, optionally, a direct action instruction can be generated according to the type of the state monitoring data to perform a corresponding protection action on the subsequent circuit, inhibit the transmission of the fault to the subsequent circuit, and protect the subsequent circuit. After the driving control instruction and / or the alarm signal are generated, if the driving state of the vehicle has returned to normal after adjustment and the state monitoring data has returned to normal, a recovery instruction can be generated to release the protection action on the subsequent circuit and restore the subsequent circuit to normal operation.

[0072] Specifically, if the status monitoring data is voltage data and the abnormality type is overvoltage abnormality, the direct action instruction is a voltage clamping instruction to clamp the voltage to protect the subsequent circuit; and after the voltage data indicates that the abnormality disappears, an unclamping instruction is output.

[0073] If the status monitoring data is current data and the abnormality type is overcurrent surge, the direct action instruction is a current cut-off instruction to cut off the current loop and protect the subsequent circuit; and when the current data indicates that the abnormality disappears, a current recovery instruction is output. Compared with the solution of cutting off the current by disconnecting the fuse in the prior art, this embodiment can restore the circuit to normal after the overcurrent abnormality disappears, reducing the impact of active protection on the normal operation of electronic equipment in the car.

[0074] If the status monitoring data is temperature data and the abnormality type is over-temperature abnormality, the direct action instruction is the current cut-off instruction to cut off the current loop and protect the subsequent circuit; and when the temperature data indicates that the abnormality disappears, the current recovery instruction is output. Since the over-temperature in the car is mainly caused by the abnormal increase of current due to faults such as short circuits in the connection circuits of electronic equipment; or the excessive power consumption of a certain device exceeds the preset temperature rise and other current-related factors. Therefore, the over-temperature problem can be effectively solved by cutting off the current.

[0075] On the basis of the above-mentioned methods, optionally, after the background database obtains the status monitoring data, it can extract the characteristic information in the status monitoring data, and summarize and analyze the characteristic information under multiple abnormal conditions. In this way, on the one hand, the abnormal judgment conditions of the status monitoring data can be updated, and the active protection device of the automobile can obtain the updated abnormal judgment conditions from the background database. In this way, the active protection method can be adjusted in a targeted and personalized manner. Secondly, the prediction function of the abnormal state can be realized. The active protection device of the automobile can obtain the characteristic information of the status monitoring data of various types of abnormalities from the background database, and judge whether the driving of the automobile has an abnormal trend by analyzing whether the current status monitoring data has characteristics close to the abnormal state, so as to timely carry out abnormal warning or preventive treatment.

[0076] Exemplarily, taking the state monitoring data as surge data as an example, the characteristic information of the surge data may include at least one of the characteristics of the surge process, such as surge amplitude, surge start time and surge duration, which can be used to describe the surge process. Among them, the surge amplitude can be understood as the peak value, valley value or peak-to-peak value of the surge monitoring data; the surge start time can be understood as the system time or local time when the surge reaches or just exceeds the safety threshold; the surge duration can be understood as the duration of the surge continuously exceeding the safety threshold or the sum of the time when the surge exceeds the safety threshold. Exemplarily, when the surge amplitude exceeds the safety threshold, it is judged that a surge has occurred. When the surge amplitude exceeds the first surge threshold, a surge reminder instruction can be output; when the surge amplitude exceeds the second surge threshold, a surge warning instruction can be output; when the surge amplitude exceeds the third surge threshold, a voltage clamping instruction or a current cut-off instruction can be output to suppress the surge from spreading to the subsequent circuit. Among them, the first surge threshold is greater than or equal to the safety threshold, the second surge threshold is greater than the first surge threshold, and the third surge threshold is greater than the second surge threshold.

[0077] Still taking surge as an example, the current driving behavior data may include the current vehicle status data analyzed based on the surge data and the vehicle operation data to preliminarily indicate the cause of the surge. Exemplarily, the surge start time is used as the surge feature, and the acceleration data is used as the vehicle operation data; then, based on the surge start time and the acceleration data at the start of the surge, it can be determined whether the vehicle is in an accelerated state at the start of the surge and recorded, and the current driving behavior data can be used as a basis for determining whether the surge is caused by vehicle acceleration. The encoding method of the above-mentioned parts of the data can be selected according to the actual situation, and is not limited here.

[0078] In summary, the embodiment of the present invention provides an active protection architecture for automobiles, which can be specifically divided into several parts: monitoring, protection, reporting, optimization and control. Specifically, the monitoring process includes: the active protection device collects status monitoring data in real time and determines whether it is abnormal; the protection process includes: when the active protection device monitors the abnormality, it outputs a protection instruction.

After the abnormality disappears, the active protection device returns to the normal monitoring state. In addition, the continuously updated historical data can provide data for the upgrading and transformation of the automobile in terms of active protection, so as to realize the re-optimization of the active protection scheme through big data analysis.
