Detailed Description
In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.
Currently, as the auxiliary driving function of a vehicle is more and more improved, more sensors are installed at various parts of the vehicle to acquire surrounding information of the vehicle in real time and provide the surrounding information to a vehicle control system, thereby helping a user to drive the vehicle. For example, in the parking process, the image sensor installed at the rear of the vehicle can acquire the image information of the environment behind the current vehicle in real time, and transmit the image information to the vehicle control system, and the vehicle control system can display the processed image on the large screen of the vehicle for the user to refer to when parking.
However, in the actual use process of the functions, the signal lock losing phenomenon can occasionally occur, namely, the sensor image information received by the vehicle control system is wrong. And the reason for generating the error can be that the sensor itself is faulty, or that the image information is configured to be faulty in the transmission process. That is, in general, the user and the vehicle system cannot directly determine the root cause of the signal loss lock, and thus, the vehicle cannot make a corresponding solution to the signal loss lock phenomenon. After signal lock loss occurs, the vehicle control system cannot accurately acquire image information around the vehicle, so that a large screen of the vehicle cannot display real-time images, which usually requires users to detect that the image information is displayed incorrectly in the using process, or manually reset a sensor after receiving alarm information, so as to attempt to solve the problem of information lock loss.
However, the solution requires manual operation of a user, which not only affects the use experience of the user on the vehicle system, but also creates a certain potential safety hazard for driving the vehicle.
Aiming at the problems, the inventor provides a signal unlocking processing method, a signal unlocking processing device, a vehicle and a storage medium, so that the vehicle can reset a sensor in time under the condition of signal unlocking, and user experience is improved. The specific method for handling signal loss lock is described in detail in the following embodiments.
The following describes a hardware environment of a signal loss lock processing method provided in the embodiment of the present application.
Fig. 1 shows an application scenario diagram of a method for processing signal loss lock according to an embodiment of the present application. The signal unlocking processing method provided by the application is applied to a parking assist integrated System (SOC) in a vehicle control System, wherein the SOC System 110 is composed of at least one main controller 111, one or more memories 112 and the like, the main controller 111 is used for acquiring and processing image data acquired by a parking sensor 120 and receiving feedback signals transmitted by various microcontrollers, and the memories 112 are used for storing the image data transmitted by the parking sensor 120. After acquiring the image data in the current environment, the parking sensor 120 in the vehicle may convert the parallel image data into serial data through the serializer 130, so as to transmit the image data to the remote SOC system 110 through a low voltage differential signaling (LVDS, low Voltage Differential Signaling) interface. Before the image data enters the main controller 111 of the SOC system 110, the vehicle may also configure the serial image data into parallel data through the deserializer 140, where the microcontroller for managing the operation of the deserializer 140 may send a prompt message to the main controller 111 in the SOC system 110 through one IO interface of the microcontroller in the case that the configuration of the image data by the deserializer 140 is abnormal or the configuration of the image data is incorrect.
The method for processing signal lock loss provided by the embodiment of the application will be specifically described below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for handling signal loss lock according to an embodiment of the present application, and the flow chart shown in fig. 2 will be described in detail, where the method for handling signal loss lock specifically includes the following steps:
step S110: and under the condition that the data transmission of the image data of the parking sensor meets the preset abnormal condition, recording the continuous loss condition corresponding to the image data transmitted by the parking sensor.
In the embodiment of the application, the main controller in the vehicle SOC system can judge whether the received image data is abnormal or not through a preset abnormal condition. If the data transmission of the image data of the parking sensor meets the preset abnormal condition, the main controller can determine that the currently received image data frame has an abnormal condition. At this time, the main controller may further record a continuous loss condition corresponding to the image data transmitted by the parking sensor, so as to determine whether to actively reset the sensor based on the continuous loss condition corresponding to the image data.
It will be appreciated that if the data transmission of the image data of the parking sensor satisfies the preset abnormal condition, it indicates that the image data received by the main controller at the current moment is wrong, but at this time, the main controller does not need to directly reset the parking sensor. This is because the erroneous image data transmitted from the parking sensor may be an error occurring only for a short time, and the image data can be automatically recovered to be normal after a short time, and if the main controller directly transmits a reset signal to the parking sensor at this time, the transmission of the reset signal and the resetting of the parking sensor all take a long time, typically at least 500 milliseconds. If the image data of the parking sensor with errors is only one or a few frames of images, the image data received by the main controller will automatically return to normal within a period of less than 500 milliseconds, and in this case, the main controller does not need to spend more time to perform additional reset operation on the parking sensor. That is, after the data transmission of the image data of the parking sensor satisfies the preset abnormal condition, the main controller still needs to further acquire the continuous loss condition corresponding to the image data transmitted by the parking sensor, so as to determine whether the image data with the error is a short-time sporadic error or a long-time continuous error, and further determine whether the parking sensor needs to be reset finally.
Specifically, the main controller judges that the data transmission of the image data of the parking sensor meets the preset abnormal condition, that is, the parking sensor cannot acquire the image data, so that the image data of the current frame which the main controller should receive is lost, that is, that the image data of the current frame which the main controller should receive is obviously wrong, or that the main controller receives an indication signal for indicating that the image data is wrong, or the like, wherein the specific preset abnormal condition is not limited, and the main controller can judge that the image data received by the main controller is wrong at the current moment only when the data transmission of the image data of the parking sensor meets the preset abnormal condition.
Step S120: and if the continuous loss condition meets a preset loss condition, outputting a reset signal to the parking sensor, wherein the reset signal is used for controlling the parking sensor to reset.
In the embodiment of the application, the main controller may determine, according to the continuous loss condition corresponding to the image data transmitted by the parking sensor, whether the data transmission of the image data is abnormal, whether only the image data of the current frame is abnormal or the image data of the continuous multiple frames is abnormal. If the continuous loss condition corresponding to the image data meets the preset loss condition, the main controller can determine that the image data of the continuous multiframe is lost currently, that is, the abnormal transmission of the image data of the parking sensor cannot be automatically recovered in a short time, so that the main controller can output a reset signal to the parking sensor to instruct the parking sensor to recover the normal transmission of the image data through the reset operation of power down and power up again.
It can be understood that the error of the image data transmitted by the parking sensor may be that the hardware of the parking sensor fails, so that the main controller cannot receive normal image data, or the parking sensor may work normally, but because of the failure of the transmission line, the image data acquired by the sensor is lost in the process of being transmitted to the main controller, so that the main controller cannot receive the image data, wherein because of more modules passing through the image data transmission process, the main controller cannot directly find an accurate failure position according to the abnormality of the received image data. Therefore, the main controller can only send a reset signal to the sensor to control the sensor to reset under the condition that the image data is judged to be abnormal, and meanwhile, the problem that the image data is abnormal due to accidental faults in the line transmission process can be solved.
According to the signal unlocking processing method, under the condition that the data transmission of the image data of the parking sensor meets the preset abnormal condition, continuous loss conditions corresponding to the image data transmitted by the parking sensor are recorded; if the continuous loss condition meets the preset loss condition, outputting a reset signal to the parking sensor, wherein the reset signal is used for controlling the parking sensor to reset. The method can accurately detect the signal unlocking condition of the parking sensor, automatically reset the sensor, solve the signal unlocking problem in time, avoid the need of manually resetting the sensor by a user, and improve the use experience of the user.
Referring to fig. 3, fig. 3 is a schematic flow chart of a method for handling signal loss lock according to another embodiment of the present application, and the flow chart shown in fig. 3 will be described in detail, where the method for handling signal loss lock specifically includes the following steps:
step S210: and under the condition that the data transmission of the image data of the parking sensor meets the preset abnormal condition, recording the continuous loss condition corresponding to the image data transmitted by the parking sensor.
In some embodiments, as shown in fig. 4, the main controller may determine whether the data transmission of the image data of the parking sensor satisfies a preset abnormal condition by:
step S211: and acquiring the indication level signal received by the abnormality indication port.
In the embodiment of the application, in order to enable the main controller to react more quickly when the data transmission of the image data of the parking sensor is abnormal, in the transmission process of the image data, the deserializer for configuring the serial image data into the parallel data can send an indication level signal to the sensor while configuring the image parameters, so that the main controller can judge whether the image data of the current frame is abnormal or not in advance before receiving the image data of the current frame, and further can react more timely under the condition that the image data is abnormal.
As can be appreciated, in the process of configuring the image parameters by the deserializer, two situations exist, one is that the configuration parameters of the deserializer are abnormal or the parameter configuration is incorrect, and at this time, the signal of the indication level sent by the deserializer to the main controller can enable the main controller to timely obtain the signal of the abnormal image data and timely make the action of recording the continuous loss situation corresponding to the image data; the other is that the configuration parameters of the deserializer are normal, and the indication level signal sent by the deserializer to the main controller is used for representing that the image data received by the deserializer are normal, and the main controller can normally receive and understand the image data transmitted by the deserializer.
In some embodiments, the deserializer may include a microcontroller having one IO pin connected to one IO pin of a controller in the vehicle SOC system, and upon abnormality of the deserializer configuration parameters, the microcontroller may output an indication level signal to the main controller that characterizes the abnormality of the image data.
Step S212: if the indication level signal is a preset level signal, recording continuous loss conditions corresponding to the image data transmitted by the parking sensor, wherein the preset level signal is used for representing that the image data configured by the deserializer is abnormal.
In this embodiment of the present application, the main controller may receive the indication level signal, and determine whether the received current frame image data is abnormal according to whether the indication level signal is a preset level signal. The preset level signal may be a low level signal or a high level signal, which is not specifically limited, and the meaning of the different level signals may be preset. If the main controller judges that the current frame of image data is abnormal according to the indication level signal, the main controller can judge whether the current image data is abnormal or is abnormal due to short-time sporadic faults or long-time mandatory faults by recording continuous loss conditions corresponding to the image data transmitted by the parking sensor, so as to further judge whether the parking sensor needs to be reset or not.
In other embodiments, as shown in fig. 5, the main controller may further determine whether the data transmission of the image data of the parking sensor satisfies the preset abnormal condition by:
step S213: it is determined whether the image data is received by the image receiving channel.
In this embodiment of the present application, the main controller may further continuously query, by means of a software program, whether the image receiving channel receives the image data. If the transmission of the image data of the parking sensor is not abnormal, the main controller can stably receive multi-frame image data in the image receiving channel; if the transmission of the image data of the parking sensor is abnormal, the main controller can also judge the abnormal state of the transmission of the image data of the parking sensor according to the fact that the image data is not received in time in the image receiving channel, and further judge whether the operation of resetting the parking sensor is needed.
It can be understood that whether image data is received or not is queried in the image channel by means of software, so that not only can the change of circuit hardware be reduced, one IO pin on the main controller is not required to be connected to one IO pin on the microcontroller in the deserializer, but also software programs can be used on more vehicle control systems, and the application range is wider.
Step S214: and if the image receiving channel does not receive the image data, recording continuous loss conditions corresponding to the image data transmitted by the parking sensor.
In the embodiment of the application, the main controller receives the image data transmitted by the parking sensor through the image receiving channel, so that if the main controller does not receive the image data in the image channel, the abnormal condition of the data transmission of the image data of the parking sensor is indicated. However, as is clear from the above analysis, the image data in which the abnormality occurs may be only the image data of the current frame, and it is not possible to determine whether the subsequent continuous multi-frame image data is abnormal, that is, whether the current abnormality is a short-time sporadic failure or a long-time inevitable failure. Therefore, the main controller can be used for further judging whether to reset the parking sensor by recording continuous loss conditions corresponding to the image data of the parking sensor.
Step S220: and if the continuous loss condition meets a preset loss condition, outputting a reset signal to the parking sensor, wherein the reset signal is used for controlling the parking sensor to reset.
In some embodiments, the main controller may determine whether the continuous loss condition corresponding to the image data satisfies the preset loss condition by:
and if the number of the continuously lost image frames in the image data transmitted by the parking sensor is greater than or equal to the preset number of frames, outputting a reset signal to the parking sensor.
The main controller can judge whether the current image data transmission is abnormal or not according to the number of continuously lost image frames in the image data transmitted by the parking sensor. It can be understood that if the number of frames of the continuously lost image is greater than or equal to the preset number of frames, the main controller can determine that the current image data transmission is abnormal and cannot automatically recover to normal, and the parking sensor needs an additional control instruction at this time to recover the image data transmission to normal. The main controller can send a reset signal to the parking sensor so as to instruct the parking sensor to perform power-down and power-up operation.
As one possible embodiment, the main controller may output a reset signal to the parking sensor in the case where the number of consecutive lost image frames is greater than or equal to 60 frames. That is, the main controller may use the image data of 60 consecutive frames as a criterion for determining whether the transmission abnormality of the image data can be automatically recovered, and if the number of frames of the image data that is continuously lost is less than 60 frames, it indicates that the main controller has received the image data again normally in a short time, and it is not necessary to recover the transmission of the image data by sending a reset command to the parking sensor.
In other embodiments, the main controller may further determine whether the continuous loss condition corresponding to the image data satisfies the preset loss condition by:
and if the duration of continuously losing the image data in the image data transmitted by the parking sensor reaches the preset duration, outputting a reset signal to the parking sensor.
The main controller can judge whether the current abnormal condition belongs to short-time sporadic faults or long-time inevitable faults through the abnormal time length of the image data transmission. If the abnormal transmission condition of the current image data belongs to a short-time occasional fault, namely the duration of continuously losing the image data in the image data transmitted by the parking sensor is smaller than the preset duration, the abnormal transmission condition of the image data can automatically recover to be normal in a short time, and the main controller does not need to perform any operation on the parking sensor or other components. However, if the abnormal transmission condition of the current image data belongs to a long-term inevitable fault, that is, the duration of continuously losing the image data in the image data transmitted by the parking sensor is longer than or equal to the preset duration, at this time, the abnormal transmission of the image data cannot be spontaneously recovered to be normal, and the main controller needs to recover the transmission of the image data by a certain control instruction. In this case, the main controller may output a reset signal to the parking sensor, and return the transmission of the image data to normal by resetting the parking sensor.
In some embodiments, the main controller may set the preset duration to a time length of 2 seconds, and if the duration of the continuous loss of the image data in the image data is greater than or equal to 2 seconds, the main controller may generate a reset signal to the parking sensor to instruct the sensor to perform a reset operation.
It should be understood that the transmission of the image data is abnormal, and the reason for the occurrence of the abnormality is not necessarily on the parking sensor, but may be that the image data is lost due to a failure of a transmission line during the transmission of the image data, or that the parking sensor is failed, but the failure cannot be resolved by a reset operation. Meanwhile, since the image data loss phenomenon is sporadic, the main controller cannot directly obtain the cause of the failure when the failure occurs. Therefore, the main controller resets the parking sensor, and only has a certain probability of restoring the transmission of the image data to be normal.
Step S230: and if the data transmission of the image data of the parking sensor meets the preset abnormal condition, repeatedly executing the steps of recording the continuous loss condition corresponding to the image data transmitted by the parking sensor until the continuous loss condition meets the preset numerical condition, and outputting a reset signal to the parking sensor.
In the embodiment of the application, as shown by the analysis, the main controller sends the reset signal to the parking sensor when the image data transmission is abnormal, so that the image data transmission is recovered to be normal only with a certain probability. Therefore, the main controller can still continuously acquire the transmission condition of the image data after transmitting the reset signal to judge whether the abnormal phenomenon is recovered. Specifically, after sending the reset signal to the parking sensor, the main controller may still determine whether the data transmission of the image data of the parking sensor satisfies the preset abnormal condition. If the data transmission of the image data meets the preset abnormal condition and the continuous loss condition corresponding to the image data transmitted by the parking sensor meets the preset numerical condition, the fact that the reset signal transmitted to the parking sensor last time does not solve the abnormal condition of the image data transmission is indicated, and at the moment, the main controller can also transmit the reset signal to the parking sensor again.
Step S240: the number of times of repeatedly transmitting the reset signal is acquired.
In this embodiment of the present application, the main controller may acquire the number of times of repeatedly sending the reset signal to the parking sensor, and according to the above analysis, it is known that the abnormal situation of the transmission of the image data may not be necessarily solved by the reset operation of the parking sensor, and if the main controller still cannot solve the abnormal situation of the transmission of the image data after sending the reset signal to the parking sensor multiple times, it indicates that the abnormal situation cannot be temporarily solved by resetting the parking sensor. Therefore, the main controller can also acquire the times of repeatedly sending the reset signal so as to judge whether the reset signal can act or not and solve the abnormal image data transmission condition.
Step S250: and if the number of times exceeds a preset value, outputting alarm information, wherein the alarm information is used for prompting the fault of the parking sensor.
In this embodiment of the present application, if the number of times that the main controller sends the reset signal to the parking sensor exceeds the preset value, it indicates that the abnormal transmission phenomenon of the image data that occurs at present cannot be simply solved by the reset operation, and at this time, the main controller may output the alarm information to prompt the user that the parking sensor fails, and the current image data cannot be normally acquired.
Referring to fig. 6, a software flow diagram of a method for handling signal lock loss according to an embodiment of the present application is shown. The main controller can acquire multi-path image data in the image receiving channels to further judge whether each image receiving channel has the image data, if the image data do not exist, the abnormal transmission phenomenon of the image data of the parking sensor is indicated, at the moment, the main controller can record the continuous loss condition of the image data, if the continuous loss condition meets the preset loss condition, a reset signal is generated to the parking sensor, and the image of the corresponding channel is blacked out; if the continuous loss condition does not meet the preset loss condition, judging whether an image is updated, if yes, updating an image memory, displaying the updated image on a large screen of the vehicle machine for reference by a user, and if no image is updated, recording the continuous loss condition of the image data again.
According to the signal lock loss processing method provided by the embodiment of the application, under the condition that the data transmission of the image data of the parking sensor meets the preset abnormal condition, the continuous loss condition corresponding to the image data transmitted by the parking sensor is recorded, wherein the preset abnormal condition can be that the main controller acquires that the indication level signal received by the abnormal indication port is the preset level signal, or can be that the image receiving channel does not receive the image data; if the continuous loss condition meets a preset loss condition, outputting a reset signal to the parking sensor, wherein the reset signal is used for controlling the parking sensor to reset, and the preset loss condition can be that the number of frames of the continuous lost image is greater than or equal to a preset number of frames, or that the duration of the continuous lost image data in the image data transmitted by the parking sensor reaches a preset duration. The method can accurately detect the signal unlocking condition of the parking sensor, automatically reset the sensor, solve the signal unlocking problem in time, avoid the need of manually resetting the sensor by a user, and improve the use experience of the user.
Referring to fig. 7, which is a block diagram illustrating a signal loss lock processing apparatus 200 according to an embodiment of the present application, the signal loss lock processing apparatus 200 includes: the anomaly determination module 210 and the reset control module 220. The anomaly determination module 210 is configured to record a continuous loss condition corresponding to the image data transmitted by the parking sensor when the data transmission of the image data of the parking sensor meets a preset anomaly condition; the reset control module 220 outputs a reset signal to the parking sensor if the continuous loss condition meets a preset loss condition, wherein the reset signal is used for controlling the parking sensor to reset.
