The embodiments described below by referring to the drawings are illustrative and intended to explain the present application and should not be construed as limiting the application.

The following describes a feeding inspection method and device for a vehicle, a vehicle and a storage medium according to embodiments of the present application with reference to the accompanying drawings. Aiming at the problems that in the related art mentioned in the background art, the vehicle fault is difficult to reproduce, so that the power supply reason of the vehicle cannot be accurately positioned and the dependence of abnormal monitoring is increased, the application provides a power supply checking method of the vehicle. Therefore, the problems that the power supply reason of the vehicle cannot be accurately positioned, abnormal monitoring dependence is increased and the like in the related art are solved, the controller is additionally arranged to wake up the source monitoring, the positioning accuracy of the power supply reason is improved, meanwhile, the power supply reason can be automatically stored when being monitored, and the dependence of the abnormal monitoring on the Internet of vehicles is reduced.

Specifically, fig. 1 is a schematic flow chart of a feeding inspection method of a vehicle according to an embodiment of the present application.

As shown in fig. 1, the method for checking the power feeding of the vehicle includes the steps of:

In step S101, a network non-sleep time period after the current vehicle is powered down is obtained.

Specifically, with rapid development of vehicle intellectualization and networking, vehicle network architecture and network management are increasingly complex, so that abnormal wake-up or non-dormancy of a network is easy to occur when a vehicle is powered down, and a power supply phenomenon occurs to the vehicle, so that the vehicle cannot be started, and in order to avoid failure investigation omission and incapability of determining specific power supply reasons to influence driving experience of a user, the embodiment of the application can rapidly and accurately position the power supply reasons of the vehicle in a vehicle networking management network section and a non-vehicle networking management network section by adding a controller wake-up source monitoring and related power supply investigation method, thereby solving the power supply investigation problem in the related technology.

Based on the above, the embodiment of the application needs to acquire the network non-dormant time after the current vehicle is powered down, namely, the network non-dormant state when the vehicle is in the powered down state, so as to further monitor whether the vehicle has a feeding problem according to the network non-dormant time.

In step S102, if the time period of the network that is not dormant is longer than the first preset time period, the current wake-up source of the current vehicle is obtained.

According to one embodiment of the application, obtaining a current wake-up source for a current vehicle includes: monitoring an address identification code corresponding to a network management frame of the current vehicle, and acquiring the monitoring duration of the address identification code; if the monitoring time length is longer than the second preset time length, the signal position corresponding to the address identification code is set as an invalid bit, otherwise, the signal position corresponding to the address identification code is set as an valid bit; and obtaining the current wake-up source of the current vehicle according to the signal bit corresponding to the address identification code.

The first preset duration and the second preset duration can be set by a person skilled in the art according to actual feed investigation requirements, or can be related durations obtained through computer simulation or multiple experiments, and are not particularly limited herein.

Specifically, in the internet of vehicles management network segment, as shown in fig. 2, after acquiring the network non-dormancy time after the current vehicle is powered down, the embodiment of the application judges whether the network non-dormancy time is greater than a first preset time, if the network non-dormancy time is greater than the first preset time (for example, 40 min), it is indicated that a wake-up source continuously wakes up the vehicle after the current vehicle is powered down, at this time, an address identification code corresponding to a network management frame of the current vehicle needs to be further acquired, the address identification code is monitored, the monitored time of the address identification code is acquired, if the monitored time is greater than a second preset time, the signal position corresponding to the address identification code is set as an invalid bit, otherwise, the signal position corresponding to the address identification code is set as a valid bit, and further, the current wake-up source of the current vehicle is obtained according to the signal position corresponding to the address identification code.

For example, when the current vehicle is in the power-down state, if the obtained time period of the network which is not dormant is longer than 40min, it is indicated that there is a wake-up source after the current vehicle is powered down to continuously wake up the vehicle, so that the vehicle is always in a working state, at this time, address identification codes corresponding to network management frames of the current vehicle, that is, scrNodeID (Identity Document, identity identification codes) of all network management frames need to be further obtained, and when the corresponding ID appears, CGW (CENTRAL GATE WAY ) or domain control starts to record scrNodeID of the network management frames; secondly, the CGW or the domain control feeds back information of all network management frames to 0x574, when the corresponding scrNodeID occurs, the corresponding signal bit is set to be a valid bit in 0x574, namely set to be 1, and the network management frames acquired after power-down are sent to the TBOX (TELEMATICS BOX, internet of vehicles system) according to the period through the CGW or the domain control, if the TBOX receives the corresponding ID for timeout for 2 seconds, the corresponding signal bit is set to be a null bit in 0x574, namely set to be clear 0, for example, the signal bit of the network management frame can be represented as 000100. Wherein, every time a frame signal is monitored to be 1, resetting the timing for 2 s; and finally, obtaining a current wake-up source of the current vehicle according to the signal bit corresponding to the address identification code, and sending the current wake-up source to the TBOX by the CGW or the domain control.

It should be noted that, in the embodiment of the present application, the vehicle is developed based on autosar network management, and autosar network characteristics are multiple master control, so each controller has a communication requirement and actively sends out a network management frame.

In step S103, if the current wake-up source is a specific wake-up source, the current power supply checking is ended, otherwise, the current wake-up source is used as an abnormal wake-up source.

Specifically, as shown in fig. 2, in the embodiment of the present application, if the current wake-up source of the current vehicle is a specific wake-up source, for example, a hazard lamp of the current vehicle is turned on, a high-voltage power-on of a trolley-bus hybrid project or a pet mode is activated, it is indicated that the current wake-up source of the current vehicle is the specific wake-up source, and no other wake-up reasons exist, and then the current power supply investigation is ended.

Further, if the current wake-up source of the current vehicle is not a specific wake-up source, it is indicated that the current wake-up source is an abnormal wake-up source, for example, the vehicle-mounted display screen is on, and the network state of the current vehicle can be determined to be in a non-sleep state, that is, an abnormal state.

According to one embodiment of the present application, after taking the current wake-up source as the abnormal wake-up source, the method further comprises: obtaining an abnormal wake-up source to generate a corresponding abnormal wake-up reason; and sending the abnormal wake-up source and the abnormal wake-up reason to the target cloud.

Specifically, after obtaining an abnormal awakening source, the embodiment of the application analyzes the abnormal awakening source through TBOX to obtain an abnormal awakening reason of the current vehicle, and sends the abnormal awakening source and the abnormal awakening reason to a target cloud, the target cloud performs data acquisition, and analyzes the abnormal awakening source and the abnormal awakening reason to obtain analysis results corresponding to the abnormal awakening source and the abnormal awakening reason of the current vehicle.

According to one embodiment of the present application, after sending the abnormal wake source and the abnormal wake cause to the target cloud, the method further includes: receiving an analysis result generated by the target cloud based on the abnormal wake-up source and the abnormal wake-up reason; determining target feeding equipment and a target feeding scene of the current vehicle according to the analysis result; and generating the feeding reason of the current vehicle according to the target feeding equipment and the target feeding scene.

Specifically, based on an analysis result generated by the target cloud to the abnormal wake-up source and the abnormal wake-up reason of the current vehicle, determining target power supply equipment and a target power supply scene of the current vehicle according to the analysis result, and finally generating the power supply reason of the current vehicle according to the target power supply equipment and the target power supply scene.

For example, in the embodiment of the present application, if the target cloud determines that the vehicle-mounted purifier of the current vehicle is still continuously purifying, the vehicle-mounted navigation is still in a navigation state or other vehicle-mounted devices in a running state according to the analysis result, it is indicated that the power supply source of the current vehicle is that the vehicle-mounted purifier is still continuously purifying or the vehicle-mounted navigation is still in a navigation state when the current vehicle is powered down, so that the current vehicle cannot sleep for a long time and is always in an abnormal wake-up state.

According to one embodiment of the present application, after generating the feeding cause of the current vehicle according to the target feeding device and the target feeding scenario, the method further includes: storing the feed reason to a preset storage device, and acquiring the storage times of the preset storage device; if the storage times are smaller than the preset storage times, continuing to store the feed reason.

According to one embodiment of the present application, the obtaining the number of times of storing the preset storage device further includes: if the storage times are greater than or equal to the set storage times, comparing the address identification codes to obtain the priority of the address identification codes, wherein the smaller the address identification codes are, the higher the priority is; and storing the feeding reason of the current vehicle according to the priority of the address identification code.

The preset storage device may be a storage device selected by a person skilled in the art according to actual use requirements, and the preset storage times may be storage times set by a person skilled in the art according to actual storage memory of the storage device, which is not specifically limited herein.

Specifically, in the non-internet of vehicles management network segment, after the power supply reason of the current vehicle is obtained according to the power supply checking method, if the power supply reason is caused by special scenes such as a hazard lamp switch, a pet mode is activated, a hybrid electric vehicle project is powered on at high voltage, and the like, a specific working state signal is sent to a bus, the bus controller stops an abnormal monitoring strategy after receiving the state signal, the network is not dormant when the specific state activation signal is not received and the network is powered off for more than one hour, at the moment, the controller starts an abnormal recording function, and stores the power supply reason to a preset storage device (for example, E side), and the fact that the E side is limited in storage memory, the E side is allowed to store three abnormal times at maximum in an ignition cycle from power off to power on again, and meanwhile, the E side data cannot be eliminated, and the E side data cannot be recorded in front through clear after sale or subsequent abnormal conditions only so as to ensure that the data record cannot be lost.

Wherein, the E side records the wake-up reason according to 1 byte as shown in table 1:

TABLE 1

	Wakeup source
		00000000	wakeup source 1
00000001	wakeup source 2
		00000010	wakeup source 3
……	……
		00111111	wakeup source 64

Therefore, the E-party in the embodiment of the present application cannot completely record all wake-up sources during recording, so that the embodiment of the present application needs to obtain the storage times of the E-party first, and if the storage times are less than the preset storage times (for example, 3 times), it is indicated that there is a storage memory in the E-party at this time, so that the feed reason can be continuously stored; if the number of storage times is greater than or equal to the set number of storage times, it is indicated that the storage memory is insufficient in the E side at this time, and therefore, it is necessary to distinguish the priority of the recorded address identification codes, and order the IDs corresponding to the wake-up reason according to 1 byte record, and the IDs according to the size of the IDs, where the smaller the IDs, the higher the priority, for example, as shown in table 2, 0x01: IGN1_RELAY output, 0x06: both wake-up reasons for the valid position light output exist at the same time, and the priority record 0x01 is recorded because the ID corresponding to the ign1_delay output is smaller.

TABLE 2

Therefore, after the serious feeding problem occurs to the vehicle, the target feeding equipment and the target feeding scene in the E side can be read through the diagnostic equipment or the specific equipment, and the feeding reason of the current vehicle can be directly positioned, so that the positioning accuracy of the feeding reason is improved.
