Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the description of the present application, unless explicitly stated and limited otherwise, the term "coupled" is to be interpreted broadly, as for example, directly coupled, indirectly coupled through an intervening medium, and as an internal communication between two devices. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
The whole vehicle control mode of the electric automobile comprises a parking mode, a driving mode and a charging mode. Referring to fig. 1, the electronic device performs signal interaction with a Battery management system (Battery MANAGEMENT SYSTEM, BMS), an On Board Charger (OBC), and a fast charging pile, wherein a fast charging wake-up signal triggered by the fast charging pile and a slow charging wake-up signal triggered by the OBC are hard line signals, and information (key On electrical signal) representing a driving mode is also the hard line signals, and other signals are CAN signals.
The electronic device is a device for controlling the electric automobile, and in implementation, the control device may be a whole automobile controller (Vehicle control unit, VCU).
The BMS acquires a quick charging connection signal (CC 2) of the quick charging gun, the CC2 represents whether the quick charging gun is connected or not, and meanwhile, the BMS performs CAN signal interaction with the quick charging pile;
The OBC acquires a slow charging connection signal (CC) and a charging control signal (CP) of the slow charging pile, wherein the CC represents whether a slow charging gun is connected or not, and the CP signal represents the power supply capacity of the slow charging pile and is a signal in a PWM wave form;
The quick charging pile sends a quick charging wake-up signal to the electronic equipment, and CAN interact with the BMS through CAN signals.
The CAN signal sometimes becomes abnormal, resulting in failure to perform mode switching accurately. For example: when the driving mode needs to be entered, the charging connection signal may be abnormal, so that the driving mode cannot be entered normally.
Based on this, the embodiment of the application provides a mode switching method, a device, an electronic device and a storage medium, wherein the method comprises the following steps: responding to the information representing the driving mode, determining whether a charging wake-up signal of the electric automobile represents wake-up and whether a charging connection signal of the electric automobile represents connection; if the charging wake-up signal is a slow charging wake-up signal, the charging connection signal is a slow charging connection signal; if the charging wake-up signal is a fast charging wake-up signal, the charging connection signal is a fast charging connection signal; if the charging wake-up signal represents that the charging wake-up signal is not wake-up and the charging connection signal represents connection, prompting whether to charge or not is carried out; and after receiving the information representing uncharged state, controlling the electric automobile to enter a driving mode.
According to the scheme, after the information representing the driving mode is received, whether the charging wake-up signal of the electric automobile represents wake-up or not and whether the charging connection signal of the electric automobile represents connection or not are determined; if the charging wake-up signal is characterized by not waking up, and the charging connection signal is characterized by being connected, the probability of abnormal charging connection signals caused by the problems of wiring harnesses and the like is higher, so that prompt on whether to charge is needed, after information representing that the charging is not performed is received, the abnormal charging connection signals are determined, and the electric automobile is controlled to enter a driving mode, so that the electric automobile can be started to run normally, and the utilization rate and the robustness of the electric automobile are improved.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems with reference to the drawings and specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
The embodiment of the application provides a first mode switching method, as shown in fig. 2, which may include:
Step S201: and responding to the information representing the driving mode, determining whether a charging wake-up signal of the electric automobile represents wake-up and whether a charging connection signal of the electric automobile represents connection.
If the charging wake-up signal is a slow charging wake-up signal, the charging connection signal is a slow charging connection signal; if the charging wake-up signal is a fast charging wake-up signal, the charging connection signal is a fast charging connection signal.
In implementation, the charging connection signal may be abnormal (for example, the charging gun is not connected in the charging port of the whole vehicle, but the charging connection signal represents connection), if the charging connection signal represents connection, the electric vehicle cannot normally start to run without entering the driving mode. While the charge connection signal is abnormal, but in practice there is no charge, the charge wake-up signal is typically indicative of not waking up. Based on this, the embodiment determines whether the charging wake-up signal of the electric vehicle represents wake-up and whether the charging connection signal of the electric vehicle represents connection after receiving the information representing the driving mode.
For example, the slow charge is ac charge, slow charge wake signal=12v, characterizing wake, slow charge wake signal=0v, characterizing no wake; slow charge connection signal = 12V, characterizing connection, slow charge connection signal = 0V, characterizing disconnection;
the rapid charging is direct-current charging, the rapid charging wake-up signal=12v, the characteristic wake-up is that the rapid charging wake-up signal=0v, and the characteristic wake-up is that the rapid charging is not performed; quick charge connect signal = 12V, characterizing connect, quick charge connect signal = 0V, characterizing disconnect.
Step S202: if the charging wake-up signal represents that the charging wake-up signal is not wake-up and the charging connection signal represents connection, prompting whether to charge or not is carried out.
As described above, the charging connection signal may be abnormal due to a wire harness or the like, but the charging wake-up signal is generally indicative of not waking up when no charging is actually performed. Therefore, when the charging wake-up signal is characterized as not being waken up and the charging connection signal is characterized as being connected, the probability of the abnormal charging connection signal caused by the problems of wire harnesses and the like is relatively high, and prompt on whether to charge is needed, so that a user can further confirm whether to charge.
The specific implementation manner of the prompt for whether to charge is not limited in this embodiment, for example, an interface including "please confirm whether to charge" is displayed through a display screen of the electric vehicle, or a voice of "please confirm whether to charge" is broadcasted, etc.
Step S203: and after receiving the information representing uncharged state, controlling the electric automobile to enter a driving mode.
In this embodiment, if the information indicating that the electric vehicle is not charged is received, it indicates that the user has confirmed that the electric vehicle is not charged, and the charging connection signal indicates that the connection is caused by an abnormality of the charging connection signal, so as to control the electric vehicle to enter the driving mode.
The specific implementation manner of triggering the information representing the uncharged information is not limited, for example, a display screen of the electric automobile displays a prompt of whether to charge in a mode of containing an interface of 'please confirm whether to charge', and a user triggers the information representing the uncharged information by clicking a key of 'uncharged' in the interface; if the prompt of whether to charge is performed by broadcasting the voice of 'please confirm whether to charge', the user triggers the information representing the uncharged state by inputting the voice of 'uncharged state'.
According to the scheme, after the information representing the driving mode is received, whether the charging wake-up signal of the electric automobile represents wake-up or not and whether the charging connection signal of the electric automobile represents connection or not are determined; if the charging wake-up signal is characterized by not waking up, and the charging connection signal is characterized by being connected, the probability of abnormal charging connection signals caused by the problems of wiring harnesses and the like is higher, so that prompt on whether to charge is needed, after information representing that the charging is not performed is received, the abnormal charging connection signals are determined, and the electric automobile is controlled to enter a driving mode, so that the electric automobile can be started to run normally, and the utilization rate and the robustness of the electric automobile are improved.
In some alternative embodiments, the mode switching method further comprises the steps of:
When the electric automobile is in a driving mode, if a PWM wave signal is detected, the slow charge wake-up signal represents wake-up, the slow charge connection signal represents connection, and the current speed of the electric automobile is smaller than a preset speed, the electric automobile is controlled to enter a slow charge mode.
In the implementation, if the speed of the electric vehicle is high during the running process of the electric vehicle, the electric vehicle suddenly enters a slow charging mode, the vehicle can lose power, and the electric vehicle runs on a highway at high risk and has the risk of being knocked into the rear.
In addition, only the slow charging connection signal represents connection, and the abnormal situation of the slow charging connection signal caused by the problems of wire harnesses and the like can occur.
Based on the above, the embodiment performs redundancy detection of the slow charge related signals, if the PWM wave signal is detected, the slow charge wake-up signal is used for representing wake-up, and the slow charge connection signal is used for representing connection, so that the electric automobile has real slow charge requirements, and if the current speed of the electric automobile is smaller than the preset speed at this time, the electric automobile is controlled to enter a slow charge mode, the occurrence of emergency stop of the electric automobile is reduced, and the running safety is improved.
In some optional embodiments, before the controlling the electric vehicle to enter the slow charging mode, it is determined that at least one of the following is satisfied:
the communication handshake message flag bit represents handshake failure;
the fast charge wake-up signal characterizes that the fast charge wake-up signal is not waken up;
the fast charge connection signal characterizes the disconnection.
In implementation, the priority of the fast charging mode is higher than that of the slow charging mode, in the slow charging process of the electric automobile, if a fast charging related signal is abnormal or the fast charging gun is inserted by mistake, the electric automobile can end the slow charging function to conduct power down, at the moment, the slow charging is ended, the fast charging is not started, the electric automobile is not fully charged, and the trip is influenced.
Based on this, the embodiment performs redundancy detection on the fast-charging related signal, so long as the handshake failure of the communication handshake message flag bit is satisfied, the fast-charging wake-up signal is characterized by not being woken up, and one of the fast-charging connection signal is characterized by not being connected, the fast-charging related signal can be normally and slowly charged, so that the real slow-charging requirement is ensured when the fast-charging mode is entered, and the fast-charging requirement is not satisfied.
In some alternative embodiments, the mode switching method further comprises the steps of:
When the electric automobile is in a driving mode, if the communication handshake message flag bit indicates that handshake is successful, the quick charge wake-up signal indicates wake-up, the quick charge connection signal indicates connection, and the current speed of the electric automobile is smaller than a preset speed, the electric automobile is controlled to enter a quick charge mode; or alternatively
When the electric automobile is in the slow charging mode, if the communication handshake message flag bit indicates that handshake is successful, the fast charging wake-up signal indicates wake-up, and the fast charging connection signal indicates connection, the electric automobile is controlled to enter the fast charging mode.
In the implementation, if the speed of the electric automobile is high during the running process of the electric automobile, the electric automobile suddenly enters a fast mode, the automobile can lose power, and the electric automobile runs on a highway at a very dangerous speed, so that the electric automobile has the risk of being knocked into the rear.
In addition, only the quick charge connection signal represents connection, and the abnormal situation of the quick charge connection signal caused by the problems of wiring harness and the like can occur.
Based on this, the embodiment carries out the redundant detection of the quick charge related signal, if the communication handshake message flag bit representation handshake is detected to be successful, the quick charge wake-up signal representation wakes up, and the quick charge connection signal representation is connected, so that the electric automobile has real quick charge requirements, and if the current speed of the electric automobile is smaller than the preset speed at this time, the electric automobile is controlled to enter the quick charge mode, the occurrence of the emergency stop of the electric automobile is reduced, and the running safety is improved.
In implementation, the priority of the fast charging mode is higher than that of the slow charging mode, only the fast charging connection signals are used for representing connection, and the situation that the fast charging connection signals are abnormal due to the problems of wiring harnesses and the like can occur. At this time, although the slow charging is finished, the fast charging is not started, so that the electric automobile is not fully charged, and the travel is influenced.
Based on this, the embodiment performs the redundancy detection of the quick charge related signal, if the communication handshake message flag bit is detected to be successful in the handshake, the quick charge wake-up signal is characterized to be waken, and the quick charge connection signal is characterized to be connected, which indicates that the electric automobile has a real quick charge requirement, controls the electric automobile to enter a quick charge mode, and ensures the real quick charge requirement when entering the quick charge mode.
The embodiment of the application provides a second mode switching method, as shown in fig. 3, which may include:
step S301: and responding to the information representing the driving mode, determining whether a charging wake-up signal of the electric automobile represents wake-up and whether a charging connection signal of the electric automobile represents connection.
If the charging wake-up signal is a slow charging wake-up signal, the charging connection signal is a slow charging connection signal; if the charging wake-up signal is a fast charging wake-up signal, the charging connection signal is a fast charging connection signal.
The specific implementation of step S301 may refer to the above embodiment, and will not be described herein.
Step S302: and if the charging wake-up signal represents that the electric vehicle is not waken, and the charging connection signal represents that the electric vehicle is not connected, controlling the electric vehicle to enter a driving mode.
In implementation, if the charging wake-up signal is characterized by not waking up and the charging connection signal is characterized by not being connected, the electric automobile is not required to be charged, and the charging connection signal is normal.
Based on this, in this embodiment, if the charging wake-up signal indicates that the vehicle is not woken up, and the charging connection signal indicates that the vehicle is not connected, the electric vehicle is directly controlled to enter the driving mode.
Above-mentioned scheme, when the wakeup signal characterization that charges is not awakened, and the connection signal characterization that charges is not connected, confirm that electric automobile does not have the demand of charging, and the connection signal that charges is normal to control electric automobile accurately and get into driving mode.
In addition, when the electric automobile is in a driving mode, a slow charging mode or a fast charging mode, if no wake-up source (fast charging wake-up signal, slow charging wake-up signal, key ON signal) exists, the electric automobile is controlled to enter a parking mode.
In implementation, when the electric automobile is in the parking mode, redundant detection of charging related signals is also required, and details are not repeated here.
