An abnormality sometimes occurs in the CAN signal, and thus the mode switching cannot be performed 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, an embodiment of the present application provides a mode switching method, an apparatus, an electronic device, and a storage medium, where the method includes: responding to the information representing the driving mode, and 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 quick charging wake-up signal, the charging connection signal is a quick charging connection signal; if the charging awakening signal represents that the charging awakening signal is not awakened and the charging connection signal represents connection, prompting whether charging is carried out; and after receiving the information representing the uncharged state, controlling the electric automobile to enter a driving mode.

The following describes the technical solutions of the present application and how to solve the above technical problems in detail with reference to the accompanying drawings and specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
An embodiment of the present application provides a first mode switching method, as shown in fig. 2, the method may include:
step S201: in response to the information characterizing the driving mode, determining whether a charging wake-up signal of the electric vehicle characterizes wake-up and whether a charging connection signal of the electric vehicle characterizes connection.
If the charging wake-up signal is a slow charging wake-up signal, the charging connection signal is a slow charging connection signal; and if the charging wake-up signal is a quick charging wake-up signal, the charging connection signal is a quick charging connection signal.
In the implementation, the problem of the wire harness and the like may cause the charging connection signal to be abnormal (if the charging gun is not connected in the charging port of the whole vehicle, but the charging connection signal is connected in a representation manner), and if the charging connection signal is connected in a representation manner, the electric vehicle cannot be started normally. And when the charging connection signal is abnormal but charging is not actually carried out, the charging wake-up signal usually represents that the charging wake-up signal is not woken up. Therefore, after the information representing the driving mode is received, whether the charging wake-up signal of the electric vehicle represents wake-up or not and whether the charging connection signal of the electric vehicle represents connection or not are determined.
Illustratively, slow charging is ac charging, a slow-charge wake-up signal of 12V characterizes wake-up, a slow-charge wake-up signal of 0V characterizes no wake-up; the slow charging connection signal is 12V and represents connection, and the slow charging connection signal is 0V and represents disconnection;
the quick charging is direct current charging, a quick charging wake-up signal is 12V, the characterization is awakened, a quick charging wake-up signal is 0V, and the characterization is not awakened; the fast charge connection signal is 12V, the representation is connected, the fast charge connection signal is 0V, and the representation is not connected.
Step S202: and if the charging awakening signal representation is not awakened and the charging connection signal representation is connected, prompting whether charging is carried out.
As described above, the charging connection signal may be abnormal due to a problem of the wire harness, and the charging connection signal is abnormal, but when there is no charging, the charging wake-up signal usually indicates that the charging wake-up signal is not wake-up. Therefore, when the charging wake-up signal representation is not woken up and the charging connection signal representation is connected, the probability of charging connection signal abnormality caused by problems such as wiring harnesses is high, and whether charging is required to be prompted, so that a user can further confirm whether charging is performed.
The specific implementation manner of prompting whether to charge is not limited in this embodiment, for example, an interface including "please confirm whether to charge" is displayed on a display screen of the electric vehicle, or a voice of "please confirm whether to charge" is broadcasted.
Step S203: and after receiving the information representing the 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 abnormal 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 non-charging state is not limited in this embodiment, for example, whether the charging state is to be prompted is performed in a manner that a display screen of the electric vehicle displays an interface including "please confirm whether the charging state is to be performed", and the user triggers the information representing the non-charging state by clicking a button of "non-charging" in the interface; if carry out the suggestion whether charge through reporting the pronunciation of "please confirm whether charge" the voice, the user triggers the information that the sign is not charged through the pronunciation of input "not charging".
According to the scheme, after the information representing the driving mode is received, whether the charging awakening signal of the electric automobile represents awakening or not and whether the charging connection signal of the electric automobile represents connection or not are determined; if the charging awakening signal is not awakened and the charging connection signal is connected in a representation manner, the probability that the charging connection signal is abnormal due to the problems of wiring harnesses and the like is higher, therefore, whether charging is needed or not is prompted, after the information that the representation is not charged is received, the charging connection signal is determined to be abnormal, the electric automobile is controlled to enter a driving mode, the electric automobile can be started normally to drive, and the utilization rate and the robustness of the electric automobile are improved.
In some optional embodiments, the mode switching method further comprises the following steps:
when the electric automobile is in a driving mode, if a PWM wave signal is detected, the slow charge wake-up signal is characterized to be woken up, the slow charge connection signal is characterized to be connected, 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, in the driving process of the electric automobile, if the speed of the electric automobile is high, the electric automobile suddenly enters a slow charging mode, the vehicle loses power, the electric automobile runs on a highway very dangerously, and the risk of rear-end collision exists.
In addition, only the slow charging connection signal represents connection, and the condition that the slow charging connection signal is abnormal due to the problems of wiring harnesses and the like can occur.
Based on this, this embodiment has carried out the redundant detection of relevant signal of slow charging, if detect PWM ripples signal, and the awakening signal of slow charging sign awakens up, and fills the connection signal sign connection slowly, shows that electric automobile has real slow charging needs, if electric automobile's present speed of a motor vehicle is less than preset speed of a motor vehicle this moment, and the motor vehicle of controlling again gets into the mode of slowly charging, reduces the emergence of the condition that electric automobile promptly stopped, has improved driving safety nature.

the flag bit of the communication handshake message represents handshake failure;
the quick-charge wake-up signal represents that the signal is not woken up;
and the quick charging connection signal represents that the connection is not performed.
In the 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 related signal of the fast charging is abnormal or a fast charging gun is inserted by mistake, the electric automobile can end the slow charging function to power off, at the moment, although the slow charging is ended, the fast charging is not started, so that the electric automobile is not fully charged, and the trip is influenced.
Based on this, the embodiment performs redundancy detection on the fast charge related signal, and as long as one of the communication handshake message flag bit representation handshake failure, the fast charge wake-up signal representation not wake-up, and the fast charge connection signal representation not connected is satisfied, the slow charge will be performed normally, so that a real slow charge requirement is ensured when the slow charge mode is entered, and no fast charge requirement is met.
In some optional embodiments, the mode switching method further comprises the following steps:
when the electric automobile is in a driving mode, if the communication handshake message flag bit represents that handshake is successful, the quick-charge wake-up signal represents wake-up, the quick-charge connection signal represents connection, and the current speed of the electric automobile is smaller than a preset speed, controlling the electric automobile to enter a quick-charge mode; or
When the electric automobile is in the slow charging mode, if the communication handshake message flag bit represents that the handshake is successful, the quick charging wake-up signal represents and wakes up, and the quick charging connection signal represents and connects, the electric automobile is controlled to enter the quick charging mode.
In the implementation, in the driving process of the electric automobile, if the speed of the electric automobile is high, the electric automobile suddenly enters a fast mode, the vehicle loses power, the driving on a highway is very dangerous, and the risk of rear-end collision exists.
In addition, only the quick-charging connection signal represents connection, and the situation that the quick-charging connection signal is abnormal due to the problems of wiring harnesses and the like can occur.
Based on this, the embodiment performs redundant detection on the related signals of the fast charge, if the communication handshake message flag representation is detected to be successful in handshake, the fast charge wake-up signal representation is awakened, and the fast charge connection signal representation is connected, which indicates that the electric automobile has a real fast charge requirement, and if the current speed of the electric automobile is smaller than the preset speed at this moment, the electric automobile is controlled to enter the fast charge mode, so that the occurrence of emergency stop of the electric automobile is reduced, and the driving safety is improved.
In implementation, the priority of the fast charging mode is higher than that of the slow charging mode, only the representation of the fast charging connection signal is connected, and the situation that the fast charging connection signal is 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 traveling is influenced.
Based on this, the embodiment performs redundancy detection on the fast charge related signals, and if it is detected that the communication handshake message flag bit representation handshake succeeds, and the fast charge wake-up signal representation wake-up, and the fast charge connection signal representation connection indicates that the electric vehicle has a real fast charge requirement, the electric vehicle is controlled to enter the fast charge mode, and a real fast charge requirement is ensured when the electric vehicle enters the fast charge mode.
