Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic flow chart of a method for determining a cause of a vehicle navigation failure according to the present invention, where the method may be performed by a device for determining a cause of a vehicle navigation failure according to the present invention, and the device may be implemented in software and/or hardware. In a specific embodiment, the apparatus may be integrated in an electronic device. The following embodiments will be described taking the example of the integration of the apparatus in an electronic device, and referring to fig. 1, the method may specifically include the following steps:
Step 101, when the vehicle navigation function fails, acquiring an abnormal data packet of a signal transmission link of the vehicle navigation signal.
The abnormal data packet comprises at least one error code, each error code is generated by at least one controller in the signal transmission link, and the controllers and the error codes are in one-to-one correspondence.
Specifically, the vehicle navigation installed on the vehicle can realize the vehicle navigation function, can realize the positioning of the vehicle, and guides the running path of the vehicle through the positioning. The operation of the vehicle navigation function of the vehicle navigation is realized based on the received vehicle navigation signal, wherein the vehicle navigation signal is a communication signal used for transmitting information capable of realizing the navigation function, and the vehicle navigation signal comprises a vehicle position signal, a satellite signal, a road section information signal and the like. The signal transmission link is a transmission channel of the vehicle navigation signal, and after the vehicle receives the vehicle navigation signal, the vehicle navigation signal is required to be transmitted to the vehicle navigation through the signal transmission link, and the signal transmission link comprises a signal transmission medium and at least one controller. The controller is a system for controlling signal transmission, such as car navigation. When the vehicle navigation function fails, the navigation result is wrong, such as vehicle positioning error, incapability of positioning the vehicle, and the like. At this time, the controller having an operation failure in the signal transmission link generates an error code, which is a digital code generated by the controller in the present invention to indicate the controller having a possible failure and the possible cause of the failure.
Fig. 2b is a block diagram of an exemplary signal transmission link of the method for determining a cause of a vehicle navigation failure according to the present invention. For example, in the signal transmission link shown in fig. 2b, if the vehicle-mounted terminal has an operation failure, the signal transmission link is interrupted at this time, so that the vehicle-mounted information entertainment system and the vehicle-mounted navigation also have operation failures, and therefore, at this time, the vehicle-mounted terminal, the vehicle-mounted information entertainment system and the vehicle-mounted navigation all generate error codes. And when the vehicle-mounted terminal and the vehicle-mounted information entertainment system have no operation faults, and only the vehicle-mounted navigation has the operation faults, the vehicle-mounted navigation can generate error codes.
After the vehicle navigation function fails and the controller in the signal transmission link generates an error code, the controller in the vehicle packs at least one error code to generate an abnormal data packet. The controller in the vehicle herein refers to any controller in the vehicle, for example, a whole vehicle controller, any controller in a signal transmission link. The electronic device executing the method receives the abnormal data packet, wherein the abnormal data packet comprises at least one error code generated by at least one controller in the signal transmission link, and the controllers are in one-to-one correspondence with the error codes. The abnormal data packet in the signal transmission link may further include contents such as a work log of each controller, which is not limited in this application.
Step 102, if it is determined that the signal transmission link is capable of transmitting the vehicle navigation signal, determining, for each error code in the abnormal data packet, a controller to be checked indicated by the error code.
Specifically, after the abnormal data packet of the signal transmission link is acquired, whether the signal transmission link can transmit the vehicle navigation signal is determined. For example, it may be determined whether the signal transmission link is capable of transmitting the car navigation signal by transmitting a test signal to the signal transmission link, by whether the test signal is capable of being transmitted in the signal transmission link. When the signal transmission link is capable of transmitting the vehicle navigation signal, the fault of the vehicle navigation function is caused by the controller. Thus, for each error code in the abnormal data packet, the controller indicated by the error code is determined as the controller to be examined. The controller to be checked indicated by the error code may be the controller generating the error code, or may be other controllers, which is not limited in the present invention.
And step 103, determining the to-be-examined controller which cannot work normally as a fault controller, and determining the fault reason according to an error code generated by the fault controller.
Specifically, after determining the controllers to be checked indicated by the error codes, checking the working state of at least one controller to be checked, and determining whether the at least one controller to be checked can work normally. The controller to be checked which cannot work normally is determined as a fault controller, and one or more fault controllers can be arranged. And determining the fault reason according to the error code generated by the fault controller, and taking the fault reason as the fault reason of the vehicle navigation.
Optionally, according to the error code generated by the fault controller and the mapping relation between the error code and the fault reason, determining the fault reason corresponding to the error code generated by the fault controller.
Specifically, a database is preset in the electronic equipment for executing the method, and a plurality of groups of mapping relations between error codes and fault reasons are preset in the database. And determining the fault reason corresponding to the error code generated by the fault controller according to the error code generated by the fault controller and the mapping relation between the preset error code and the fault reason.
The fault controller is an in-vehicle navigation, the error code generated by the in-vehicle navigation is 1, and in the mapping relation between the error code of the database and the fault cause, the fault cause corresponding to the error code 1 is damage to the in-vehicle navigation internal device. Therefore, the failure cause of the vehicle navigation is determined to be damage to the internal components of the vehicle navigation.
According to the scheme, when the vehicle navigation function fails, an abnormal data packet of a signal transmission link of a vehicle navigation signal is acquired; the abnormal data packet comprises at least one error code, each error code is generated by at least one controller in the signal transmission link, and the controllers and the error codes are in one-to-one correspondence; if the signal transmission link is determined to be capable of transmitting the vehicle navigation signal, determining a to-be-examined controller indicated by the error code aiming at each error code in the abnormal data packet; and determining the to-be-examined controller which cannot work normally as a fault controller, and determining the fault reason according to an error code generated by the fault controller. On one hand, the scheme of the invention determines whether the signal transmission link can transmit the vehicle navigation signal, so that the probability of misjudgment during fault determination can be reduced, and the reliability of fault determination can be improved. On the other hand, the fault cause is determined according to the error code, so that the dependence on professional staff during fault determination is reduced, the efficiency of fault cause determination is improved, and the fault determination time is shortened.
Fig. 2a is another flow chart of the vehicle navigation fault cause determining method provided by the present invention, and this embodiment is based on the embodiment shown in fig. 1 and various alternative implementations, to describe in detail whether the signal transmission link is capable of transmitting the first test signal, and to describe in detail the output result of transmitting the second test signal to the controller to be examined to determine the controller to be examined. As shown in fig. 2a, the method may comprise the steps of:
step 201, when the vehicle navigation function fails, acquiring an abnormal data packet of a signal transmission link of the vehicle navigation signal.
Specifically, when the vehicle navigation function fails, a navigation result is wrong, for example, a vehicle is positioned in error, the vehicle cannot be positioned, and the like. At this time, an abnormal data packet of the signal transmission link of the vehicle navigation signal is acquired, the abnormal data packet includes at least one error code generated by at least one controller in the signal transmission link, and the controllers are in one-to-one correspondence with the error codes. The controller in the signal transmission link is a system for controlling signal transmission.
Step 202, determining whether the signal transmission link is capable of transmitting the first test signal according to the phenomenon of the signal transmission link after the first test signal is transmitted.
Specifically, the first test signal is a signal for testing the signal transmission link. After the first test signal is transmitted to the signal transmission link, the phenomenon of the signal transmission link after the first test signal is transmitted is obtained, and whether the signal transmission link can transmit the first test signal is determined according to the phenomenon of the signal transmission link after the first test signal is transmitted.
Step 203, if the phenomenon of the signal transmission link is inconsistent with the preset phenomenon, determining that the signal transmission link cannot transmit the vehicle navigation signal, and determining that the failure cause is that the signal transmission link is broken.
Specifically, the preset phenomenon is a phenomenon generated after the signal transmission link transmits the first test signal when the signal transmission link can transmit the vehicle navigation signal. For example, the preset phenomenon may be that the signal transmission link may transmit the first test signal. If the phenomenon of the signal transmission link is inconsistent with the preset phenomenon, the signal transmission link is not capable of transmitting the vehicle navigation signal, and the reason of the fault is determined to be that the signal transmission link is broken.
Step 204, if the phenomenon of the signal transmission link is consistent with the preset phenomenon, determining that the signal transmission link can transmit the vehicle navigation signal.
Specifically, if the phenomenon of the signal transmission link is consistent with the preset phenomenon, it is indicated that the signal transmission link can transmit the vehicle navigation signal, and it is indicated that the failure of the vehicle navigation function is caused by the controller.
Step 205, if it is determined that the signal transmission link is capable of transmitting the vehicle navigation signal, determining, for each error code in the abnormal data packet, a controller to be checked indicated by the error code.
Specifically, when the signal transmission link is capable of transmitting the vehicle navigation signal, it is indicated that the failure of the vehicle navigation function is caused by the controller. Thus, for each error code in the abnormal data packet, the controller indicated by the error code is determined as the controller to be examined. The controller to be checked indicated by the error code may be the controller generating the error code, or may be other controllers, which is not limited in the present invention.
Step 206, for each controller to be inspected, sending a second test signal to the controller to be inspected, and determining an output result of the controller to be inspected.
Specifically, the second test signal is a signal for testing the controller to be examined. After the controller to be checked indicated by the error code is determined, whether the controller to be checked can work normally or not is determined. The mode of determining whether the controllers to be checked can work normally is that a second test signal is sent to each controller to be checked respectively, and an output result of the controller to be checked is obtained.
In one possible implementation, the signal transmission link includes a signal transmission medium and at least one controller. The transmission medium comprises an antenna and an inter-network connection device, and the controller comprises a vehicle navigation controller and an intermediate controller. The antenna, the intermediate controllers and the vehicle-mounted navigation are sequentially connected, the antenna is connected with one intermediate controller, the intermediate controllers are directly connected or connected through the inter-network connecting equipment, and the intermediate controllers are directly connected with the vehicle-mounted navigation or connected through the inter-network connecting equipment. The transmission direction of the vehicle navigation signal in the signal transmission link is from the antenna to the vehicle navigation through the intermediate controller in sequence.
Further, the inter-network connection device is a gateway. The intermediate controller comprises a vehicle-mounted information entertainment system and a vehicle-mounted terminal. The antenna is connected with one end of the vehicle-mounted terminal, the other end of the vehicle-mounted terminal is connected with one end of the gateway, the other end of the gateway is connected with one end of the vehicle-mounted information entertainment system, and the other end of the vehicle-mounted information entertainment system is connected with the vehicle-mounted navigation. The controller to be examined comprises at least one of a vehicle navigation system, a vehicle infotainment system and a vehicle terminal.
Illustratively, as shown in FIG. 2b, the signal transmission link includes an antenna, an in-vehicle terminal, a gateway, an in-vehicle infotainment system, and in-vehicle navigation. The signal transmission medium comprises an antenna and a gateway, and the intermediate controller comprises a vehicle navigation system and a vehicle information entertainment system. The antenna, the vehicle-mounted terminal, the gateway, the vehicle-mounted information entertainment system and the vehicle-mounted navigation are sequentially connected. The antenna is connected with the vehicle-mounted terminal through a wire harness, the vehicle-mounted terminal is connected with the gateway through an Ethernet, the gateway is connected with the vehicle-mounted information entertainment system through the Ethernet, and the vehicle-mounted information entertainment system is connected with the vehicle-mounted navigation through an interface.
Optionally, for each controller to be examined, a second test signal is sent to the controller to be examined, and determining the output result of the controller to be examined may be implemented through steps 2061 to 2062.
Step 2061, determining the order of the transmission directions of the controllers to be inspected in the signal transmission link as the inspecting order of the controllers to be inspected.
The transmission direction of the controller to be examined in the signal transmission link is from the antenna to the vehicle-mounted terminal, the vehicle-mounted terminal to the vehicle-mounted infotainment system, and the vehicle-mounted infotainment system to the vehicle-mounted navigation. And when the controller to be checked is a vehicle-mounted information entertainment system and a vehicle-mounted navigation system, the order of the reverse direction of the transmission direction of the controller to be checked in the signal transmission link is from the vehicle-mounted navigation to the vehicle-mounted information entertainment system. Therefore, the checking sequence of the controllers to be checked is determined to be checking the vehicle navigation first and then checking the vehicle information entertainment system.
The order of the reverse direction of the transmission direction of the to-be-inspected controller in the signal transmission link is determined as the inspection order of the to-be-inspected controller, because the problem phenomenon can be solved, and the efficiency of determining the fault cause can be improved. In the present embodiment, the problem is that the vehicle navigation function fails, so that the direction from the vehicle navigation to the antenna can be examined. In this embodiment, an error code generated by the controller to be inspected, which has a fault phenomenon, indicates the controller to be inspected. And when the upstream controller in the transmission direction of the signal transmission link fails, the downstream controller is caused to generate an error code. In the signal transmission link, when a plurality of upstream controllers are connected or correspond to one downstream controller, the failure determination efficiency is low due to direct checking from the upstream controllers, and the efficiency of the failure cause determination can be improved due to sequential checking along the direction opposite to the transmission direction in the transmission link. After the output result of the controllers to be checked with the fault phenomenon is determined, the next controller to be checked with the reverse direction of the transmission direction can be determined according to the error code generated by the controllers to be checked, all the controllers do not need to be checked one by one, the efficiency of determining the fault cause is improved, and the fault determining time is shortened.
Step 2062, sequentially sending a second test signal to the to-be-inspected controller according to the inspecting sequence of the to-be-inspected controller, and determining the output result of the to-be-inspected controller.
Specifically, after determining the checking sequence of the controllers to be checked, sequentially sending a second test signal to the controllers to be checked according to the checking sequence of the controllers to be checked, and determining the output result of each controller to be checked.
The checking sequence of the to-be-checked controller is that the vehicle navigation is checked firstly, and then the vehicle information entertainment system is checked. Firstly, a second test signal is sent to the vehicle-mounted navigation, the output result of the vehicle-mounted navigation is determined, and then the second test signal is sent to the vehicle-mounted information entertainment system, and the output result of the vehicle-mounted information entertainment system is determined.
Step 207, if the output result of the to-be-inspected controller is consistent with the preset result, determining that the to-be-inspected controller is a to-be-inspected controller capable of operating normally.
Specifically, the preset result is an output result of the controller to be inspected after the second test signal is sent to the controller to be inspected when the controller to be inspected can work normally. If the output result of the to-be-inspected controller is consistent with the preset result, determining that the to-be-inspected controller is the to-be-inspected controller which can work normally.
The controller to be examined is a vehicle navigation device, and the preset result sent to the vehicle navigation device by the second test signal is that the vehicle navigation device is positioned currently. After the second test signal is sent to the vehicle navigation, the output result is that the vehicle navigation is positioned currently, the output result is consistent with the preset result, and the vehicle navigation is determined to be the controller to be checked which can work normally.
And step 208, if the output result of the to-be-inspected controller is inconsistent with the preset result, determining that the to-be-inspected controller is the to-be-inspected controller which can not work normally.
The controller to be examined is a vehicle navigation device, and the preset result sent to the vehicle navigation device by the second test signal is that the vehicle navigation device is positioned currently. After the second test signal is sent to the vehicle navigation, if the output result is that the vehicle navigation does not present the current positioning, the output result is inconsistent with the preset result, and the vehicle navigation is determined to be the controller to be checked which can not work normally.
And step 209, determining the to-be-examined controller which cannot work normally as a fault controller, and determining the fault reason according to an error code generated by the fault controller.
Specifically, the to-be-examined controller which cannot work normally is determined as a fault controller, and one or more fault controllers can be used. And determining the fault reason according to the error code generated by the fault controller, and taking the fault reason as the fault reason of the vehicle navigation.
It should be understood that, although the steps in the flowchart of fig. 2a are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 2a may comprise a plurality of sub-steps or phases, which are not necessarily performed at the same time, but may be performed at different times, the order of execution of which may not necessarily be sequential, but may be performed in rotation or alternatively with at least a portion of the sub-steps or phases of other steps or steps.
According to the scheme of the invention, whether the signal transmission link can transmit the vehicle navigation signal or not is determined according to the phenomenon of the signal transmission link after the first test signal is transmitted, the probability of misjudgment during fault determination is reduced, and the reliability of fault determination is improved. And the checking sequence of the controllers to be checked is determined according to the transmission direction in the signal transmission link, and the error code indicates the controllers to be checked, so that after the output result of the controllers to be checked with the fault phenomenon is determined, the next controller to be checked can be determined according to the error code generated by the controllers to be checked, the efficiency of determining the fault reason is further improved, and the fault determining time is shortened.
