For convenience of understanding and explanation, a vehicle safety protection method, a system, a vehicle and a storage medium provided by the embodiments of the present application are described in detail below with reference to fig. 4 to 8.
Fig. 4 is a schematic flowchart of a vehicle safety protection method according to an embodiment of the present invention, where the method may be executed by a vehicle safety protection system, and the system may be implemented as part of or all of the vehicle safety protection system through software, hardware, or a combination of software and hardware. As shown in fig. 4, the method includes:
s101, the vehicle door controller acquires a safety locking signal and sends the safety locking signal to the engine controller, wherein the safety locking signal is generated after the closing state of each vehicle door travel switch and each trunk travel switch in the vehicle are detected.
Specifically, the safety locking signal is used for indicating the closing state of each door travel switch and each trunk travel switch in the vehicle, and is generated according to the detected closing state of each door travel switch and each trunk travel switch in the vehicle. The safety locking signal may comprise two states, one being an open state and the other being a closed state. When all door travel switches and trunk travel switches in the vehicle are closed, the safety locking signal is in a closed state; when any one of the door travel switches or the trunk travel switches in the vehicle is not closed, the safety locking signal is in an off state.
The door controller may detect the safety lock signal and send the safety lock signal to the engine controller. Wherein, the safety locking signal may be sent to the engine controller within a preset period. The preset period is set according to actual requirements in a self-defined mode, and can be 1000ms, namely, the vehicle door controller sends a safe locking signal to the engine controller every 1000 ms.
S102, when the engine controller detects a shielding mode and determines that the vehicle accords with a safe driving rule, shielding the safe locking signal based on the shielding mode and controlling the engine to normally work; the shielding modes comprise a first shielding mode and a second shielding mode, and the first shielding mode is generated when the gear switch is switched to the isolation mode; the second shielding mode is generated by the telematics device based on the configured security lock-out signal soft-shield function parameter.
It should be noted that, the above-mentioned shielding mode refers to shielding the safety locking signal, that is, no matter which state the safety locking signal is in, the normal operation of the vehicle is not affected, that is, no matter which state the door travel switches and the trunk travel switch are in, or the off state, the normal operation of the vehicle is not affected.
The shielding mode may include a first shielding mode and a second shielding mode, where the first shielding mode is to shield the security locking signal by a physical method; the second shielding mode is to shield the safety locking signal in a software mode, and is generated by the vehicle-mounted information device based on the configured safety locking signal soft shielding function parameter. The first shielding mode or the second shielding mode is caused when the safety locking signal is not closed, which may be caused when the trunk cannot be closed due to the fact that the vehicle transports large articles, or when the isolation mode is triggered due to the fact that the locking signal cannot be closed due to accidents and other reasons.
It should be noted that the first shielding mode is generated when the shift switch is switched to the isolation mode. The gear switch can be a selector switch, and the selector switch can be switched to two different gear modes, namely a normal mode and an isolation mode. As shown in fig. 5, if the shift switch is in the normal mode, the shift switch is connected in series with each door travel switch and each trunk travel switch in the vehicle. If all door travel switches and trunk travel switches in the vehicle are in a closed state, a safety locking signal is generated and is in the closed state. If any one of the door travel switches or the trunk travel switch in the vehicle is in an off state, a safety locking signal is generated and is in the off state.
If the gear switch is switched to the isolation mode, the gear switch is not connected in series with each door travel switch and trunk travel switch in the vehicle, but is directly connected with the controller, for example, directly connected with the controller through a wire. When the gear switch is switched to the isolation mode, the safety locking signal is directly generated, and the normal work of the vehicle is not influenced by the safety locking signal.
Specifically, the engine controller may detect a shielding mode, and control the engine to operate normally by detecting whether the vehicle is in a first shielding mode or a second shielding mode, and performing shielding processing on the safety lock signal based on the shielding mode when the first shielding mode or the second shielding mode is detected.
As an optional implementation manner, in the process of detecting whether the vehicle is in the first shielding mode, the mode information of the gear switch may be monitored by the gear monitoring circuit to detect a locking mode signal, when the locking mode signal indicates that the gear switch is switched to the isolation mode, it is determined that the vehicle is currently in the first shielding mode, and otherwise, it is determined that the vehicle is not currently in the first shielding mode. In the process of detecting whether the vehicle is in the second shielding mode, whether a soft shielding signal can be received or not can be checked from the vehicle-mounted information device, the soft shielding signal is generated based on the configured soft shielding function parameter of the safety locking signal, when the soft shielding signal is received, the vehicle is determined to be in the second shielding mode currently, otherwise, the vehicle is determined not to be in the second shielding mode currently.
When the engine controller detects the shielding mode, namely detects that the vehicle is in the first shielding mode or the second shielding mode, the vehicle is determined to accord with the safe driving rule, and the safe locking signal is shielded based on the shielding mode to control the engine to normally work when the driving parameters of the vehicle are determined to be normal. For example, when it is determined that the trunk cannot be closed due to the fact that the vehicle transports large articles, or when the locking signal cannot be closed due to other reasons such as accidents and the like, but other system parameters are normal, the safety locking signal is shielded, and the engine is controlled to normally work.
The application provides a vehicle safety protection method, a vehicle door controller is used for obtaining a safety locking signal and sending the safety locking signal to an engine controller, the safety locking signal is generated after a gear switch detects the closing state of each vehicle door travel switch and a trunk travel switch, when the engine controller detects a shielding mode and determines that a vehicle accords with a safety driving rule, the safety locking signal is shielded based on the shielding mode to control the engine to normally work, the shielding mode comprises a first shielding mode and a second shielding mode, and the first shielding mode is generated when the gear switch is switched to the isolation mode; the second masking mode is generated by the telematics device based on the configured secure lock-out signal soft-mask function parameter. According to the technical scheme, the first shielding mode and the second shielding mode are arranged, so that when a user uses a vehicle to transport large articles or some special scenes to cause that a vehicle door or a trunk cannot be closed, the shielding modes can be automatically detected, a safety locking signal of the vehicle is shielded in a physical or software configuration mode to control the engine to normally work, normal starting of the vehicle is guaranteed, labor cost is reduced, waste of social resources is avoided, the first shielding mode and the second shielding mode can be mutually backed up for use, and system availability is improved.
In another embodiment of the present application, a method for monitoring whether a security locking signal is shielded is further provided, and specifically, before shielding the security locking signal based on a shielding mode, an engine controller may further generate a corresponding information prompt instruction based on a first shielding mode and a second shielding mode, where the information prompt instruction is used to prompt a user whether to continue shielding the security locking signal, and then perform information prompt on the first shielding mode or the second shielding mode in response to the information prompt instruction.
Specifically, when the user forgets to cancel the physical isolation mode for recovery by using the vehicle physical isolation at a certain time, if the first shielding mode is detected during the use of the vehicle in the next driving cycle, that is, after the ignition of the engine controller, an information prompt instruction corresponding to the first shielding mode may be generated based on the first shielding mode, the information prompt instruction including information prompt contents corresponding to the first shielding mode, and the information prompt may be performed for the first shielding mode in response to the information prompt instruction corresponding to the first shielding mode.
Optionally, the information prompt instruction may be prompted in a voice broadcast manner, or may be prompted in a screen display manner of a DHU in the vehicle. The information prompt content may be, for example, "hello, that the vehicle safety lock signal is not formed currently, that the vehicle safety lock signal is in a physically isolated state, and that whether the first shielding mode is used is asked to be continued? And prompting the user whether to continue to isolate and shield the safety locking signal.
It should be noted that the above-mentioned one driving cycle of the vehicle refers to the whole process from the ignition of the vehicle to the flameout of the vehicle.
Further, when the user is isolated by using the software mode at a certain time, that is, when the engine controller detects the second shielding mode after ignition, an information presentation instruction corresponding to the second shielding mode may be generated based on the second shielding mode, the information presentation instruction including information presentation contents corresponding to the second shielding mode, and the information presentation for the second shielding mode may be performed in response to the information presentation instruction corresponding to the second shielding mode.
Optionally, the information prompt instruction may be prompted in a voice broadcast manner, or may be prompted in a screen display manner of a DHU in the vehicle. The information prompt content may be, for example, "do you well, do not form a current vehicle security lock signal, are in a software isolated state, ask whether to continue using the second mask mode? ", to remind the user whether to continue to mask the secure lock-out signal.
In addition, the soft shielding function parameters of the safety locking signal can be set, the shielding period of the safety locking signal in the first shielding mode is modified to be effective in one driving period, and the software mode is isolated and failed after the vehicle is shut down, so that the situation that the vehicle owner forgets to recover the vehicle to be in the normal mode can be effectively prevented, and the use safety of the vehicle is improved.
In the embodiment, whether the safety locking signal is shielded or not is prompted in an information prompting mode, so that a user can be timely reminded to confirm whether to continue using the shielding mode or not, and the safety of the user in using the vehicle is further ensured.
In another embodiment of the present application, fig. 6 is a schematic flow chart of a vehicle safety protection method provided in the embodiment of the present application. As shown in fig. 6, the method includes:
s201, when the engine controller does not detect the shielding mode, acquiring a safety locking signal and vehicle speed information.
And S202, judging whether the engine is controlled to normally work or not based on the safety locking signal and the vehicle speed information.
It should be noted that the speed information of the vehicle may be obtained by a wheel speed sensor on a wheel axle of the driving wheel, and may be calculated by a preset formula according to a wheel diameter of the vehicle when the vehicle leaves a factory.
In the embodiment of the present application, please refer to fig. 7, in the process of detecting the shielding mode after ignition, when the shielding mode is not detected, that is, the first shielding mode is not detected by the gear monitoring circuit and the second shielding mode is not detected, the safety locking signal may be obtained, and whether the safety locking signal is in the off state is determined by detecting the closed states of each door travel switch and the trunk travel switch of the vehicle, that is, whether any one of each door travel switch and the trunk travel switch of the vehicle has the open state is detected; when the safety locking signal is determined to be in a closed state, namely all door travel switches and trunk travel switches of the vehicle are closed, the engine is allowed to output, and the engine is controlled to normally work; when the safety locking signal is determined to be in a disconnected state, namely any one of a vehicle door travel switch and a trunk travel switch of the vehicle is opened, judging whether the vehicle speed information is zero, and when the vehicle speed information is determined to be zero, prohibiting the output of an engine, namely controlling the stopping power output of the engine; and when the vehicle speed information is determined to be not zero, allowing the engine to output, namely controlling the engine to work normally.
In the process of judging whether the safety locking signal is in the off state, the vehicle door controller may send the safety locking signal to the engine controller in a preset period, and when the engine controller does not acquire the safety locking signal within a first preset time, it is determined that the safety locking signal is in the off state. The one preset period and the first preset time may be set by a user according to actual needs, where the one preset period may be 1000ms, for example, and the first preset time may be 3000ms, for example. For example, the door controller may send the safety lock signal to the engine controller every 1000ms, and when the engine controller does not acquire the safety lock signal for more than 3000ms, the safety lock signal is determined to be in an off state for safety reasons.
In this embodiment, when the shielding mode is not detected, the off state of the safety locking signal is determined by detecting whether each door travel switch and the trunk of the vehicle are closed, so as to determine whether the engine normally works based on the safety locking signal and the vehicle speed information, and when the vehicle speed is zero and the safety locking signal is in the off state due to the fact that each door travel switch and the trunk of the vehicle are not closed, the output of the engine is prohibited, so that personal injuries and deaths and property losses caused by sudden starting of the vehicle with the doors not closed are avoided.
In another embodiment of the application, the vehicle-mounted information device acquires a safety locking signal and a locking mode signal from the vehicle door controller by taking second preset time as a period, and acquires a soft shielding function parameter of the safety locking signal from the engine controller, wherein the locking mode signal is generated when the gear switch is switched to a normal mode or an isolation mode; and the vehicle-mounted information device carries out information prompt based on the safety locking signal, the locking mode signal and the safety locking signal soft shielding function parameter.
It should be noted that the engine controller has a configuration function of a soft shielding function parameter of a safety locking signal, where the soft shielding function parameter of the safety locking signal is a configuration parameter required when the safety locking signal is shielded in a software manner, and the configuration parameter may be displayed on an interface through the vehicle-mounted information device, and may include parameters such as time of the soft shielding function, for example, a "soft shielding function enable of the safety locking signal" option may be displayed on the interface, and a user may operate the option on the interface, for example, select "soft shielding function enable of the safety locking signal" as enable, or select "soft shielding function enable of the safety locking signal" as disable, so that the vehicle-mounted information device shields the safety locking signal according to the configured soft shielding function parameter of the safety locking signal. The configured functional parameters are effective in one driving period, and when the vehicle is shut down, the configured functional parameters are automatically cleared.
Specifically, the vehicle-mounted information device may obtain a safety locking signal and a locking mode signal from the vehicle door controller with a second preset time as a period, where the locking mode signal is generated when the gear switch is switched to the normal mode or the isolation mode, and obtain a soft shielding function parameter of the safety locking signal from the engine controller with the second preset time as the period.
As an implementation manner, after the vehicle is ignited and started, if it is detected that the locking mode signal is in the isolation mode, that is, when it is detected that the vehicle is in the first shielding mode, a corresponding information prompt instruction is generated, and the information prompt is performed on the safety locking signal through the information prompt instruction to prompt a user whether to return to the normal mode or continue to use the first shielding mode. And the second preset time is set by the user in a self-defined way according to the actual requirement in advance.
As another implementation manner, after the vehicle is ignited and started, if it is detected that the soft shielding function parameter of the safety locking signal is configured, that is, when it is detected that the vehicle is in the second shielding mode, a corresponding information prompt instruction is generated, and the information prompt is performed on the safety locking signal through the information prompt instruction to prompt a user whether to return to the normal mode or continue to use the second shielding mode.
As another implementation manner, after the safety locking signal and the configured parameters of the soft shielding function of the safety locking signal are acquired, when it is detected that the safety locking signal is in an off state and the "soft shielding function of the safety locking signal is enabled" is not enabled, when it is detected that the accelerator is stepped on, a corresponding information prompt instruction may be generated, and the information prompt instruction is used to perform information prompt on the safety locking signal so as to prompt a user that the safety locking signal is off, that is, that there is an open in each door travel switch or trunk travel switch in the vehicle.
Optionally, the information prompting instruction may prompt information in a sound or screen display manner. When information is prompted in a screen display mode, prompting can be specifically performed in a pop-up window mode.
For example, when the vehicle-mounted information device is a DHU, the DHU may acquire the safety lock signal and the lock mode signal from the vehicle door controller at a cycle of 1000ms, and simultaneously acquire a configurable parameter "the safety lock signal soft-shielding function is enabled" from the engine controller at a cycle of 1000ms, and display the same on the interface for prompting. After the vehicle is re-ignited, if the locking mode signal is detected to be in the isolation mode, an acousto-optic prompt can be sent out and displayed on the DHU interface in a pop-up window mode to prompt the vehicle owner to return to the normal mode or continue to use the isolation mode; when the safety locking signal is disconnected and the 'safety locking signal soft shielding function enable' is not enabled, the accelerator is detected to be stepped on, an acousto-optic prompt can be sent out and displayed on a popup window of a DHU interface to prompt a vehicle owner that the safety locking signal is in a disconnected state.
In the embodiment, when the ignition of the vehicle is started, the information prompt is carried out on the user, and the user is timely reminded whether to remove the shielding mode or not so as to avoid causing risks.
In another embodiment of the application, a mode for detecting whether the vehicle has the behavior of getting on or off the vehicle is further provided, the speed information and the safety locking signal of the vehicle can be obtained through the vehicle door controller, and when the speed information of the vehicle is determined to be zero and the safety locking signal is in an off state, the behavior of getting on or off the vehicle is determined to exist in the vehicle; and when the vehicle door controller determines that the speed information of the vehicle is not zero and the safety locking signal is in a closed state, determining that the vehicle does not have the behavior of getting on or off the vehicle.
The speed information of the vehicle is zero, which indicates that the vehicle is in a stationary state, and when the safety locking signal is in an off state, which indicates that each door travel switch or trunk switch in the vehicle is open, the vehicle has a behavior of getting on or off the vehicle by a user; the speed information of the vehicle is not zero, the vehicle is in a running state, and when the safety locking signal is in a closed state, the vehicle indicates that all door travel switches or trunk switches in the vehicle are closed, so that the vehicle does not have the behavior of getting on or off the vehicle by a user.
According to the embodiment of the application, whether the vehicle has the behavior of getting on or off the vehicle can be determined through the speed information and the safety locking signal of the vehicle, so that the driving of a user when the behavior of getting on or off the vehicle exists can be avoided, and the driving safety of the vehicle is ensured.
