In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or 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.
With the popularization of automobile electric control systems, more or less automobiles produced at present are provided with the automobile electric control systems. However, the types of the electric control systems used are more and more along with the increase of the types of the vehicles in the vehicle factories. For example, there are 20 models under a certain vehicle manufacturer flag, and there are 10 or more engine ECUs mounted. It is difficult, if not expert, to determine which engine ECU is fitted to a particular vehicle.
Therefore, the scheme provides a solution for automatically identifying the electric control system of the current automobile assembly, and helps a user to accurately select the most suitable diagnosis system to perform diagnosis function operation on the automobile.
For convenience of understanding, a specific flow in the embodiment of the present application is described below, and referring to fig. 1, an embodiment of an automatic matching method for an automobile diagnostic system in the embodiment of the present application may include:
101. sending a diagnosis request command to the electronic control system to be tested by adopting one of preset communication protocols, and if receiving a first response message sent by the electronic control system to be tested, determining that the current communication protocol is a target communication protocol adopted by the electronic control system to be tested;
in actual application, communication protocols adopted by different vehicles may be different, common automobile communication protocols include a CAN BUS protocol, a KWP protocol and the like, and specific communication protocols are not limited herein. When the electronic control system is diagnosed, a communication protocol adopted by the electronic control system to be tested needs to be determined.
Specifically, at least two preset communication protocols are preset in the vehicle diagnosis device to adapt to more electric control systems. The vehicle diagnosis equipment can send a diagnosis request command to the electronic control system to be tested by adopting one of preset communication protocols, if a first response message sent by the electronic control system to be tested is received, the current communication protocol is determined to be a target communication protocol adopted by the electronic control system to be tested, if the first response message sent by the electronic control system to be tested is not received, the communication protocol adopted by the electronic control system to be tested is not the communication protocol used in the current testing process, and other communication protocols in the preset communication protocols are adopted to send the diagnosis request command to the electronic control system to be tested until the target communication protocol adopted by the electronic control system to be tested is detected.
For example, there are 5 types of engine EMS systems, 2 types of engine EMS systems are based on the KWP protocol, and 3 types of engine EMS systems are based on the CAN BUS protocol, and if there is no reply command, the vehicle EMS system will communicate with the diagnostic system based on the CAN BUS protocol, and the communication protocol used by the engine EMS system will be the CAN BUS protocol.
Optionally, the electronic control system to be tested in the embodiment of the present application may be an engine system, a transmission system, or an anti-lock braking system.
102. Sending a group of preset data stream commands to the electric control system to be tested by adopting a target communication protocol, and receiving a second response message sent by the electric control system to be tested;
after the target communication protocol adopted by the electric control system to be tested is determined, the electric control system to be tested can be communicated with. In the embodiment of the application, a target communication protocol can be adopted to send a group of preset data stream commands to the electric control system to be tested, receive a second response message sent by the electric control system to be tested, and determine the diagnosis system matched with the electric control system to be tested according to the second response message.
In practical applications, each type of diagnostic system has different points from other diagnostic systems, which are specifically embodied in that the data stream commands are different. Specifically, at least two groups of preset data stream commands can be preset in the vehicle diagnosis device in advance so as to adapt to more electronic control systems to be tested.
103. And judging whether the second response message meets a preset condition, and if so, determining that a target diagnosis system corresponding to a group of preset data stream commands currently used is matched with the electric control system to be tested.
And if all the preset data stream commands in the currently used group of preset data stream commands are responded and the response values are within the preset range, determining that the second response message meets the preset condition, and determining that the electronic control system to be tested is matched with the diagnostic system corresponding to the currently adopted group of data stream commands.
Optionally, the group of preset data stream commands includes at least two preset data stream commands, and the number of the specific preset data stream commands may be reasonably set and modified according to actual requirements, which is not limited herein.
For example, if there are 5 types of engine systems, 2 types of engine systems are based on the KWP protocol, and 3 types of engine systems are based on the CAN BUS protocol, the diagnostic system based on the KWP protocol is called to communicate with the EMS system of the vehicle, and if there is no reply command, the diagnostic system based on the CAN BUS protocol communicates with the vehicle. If a reply command exists, the EMS system assembled on the vehicle is the CAN BUS protocol, then the diagnostic systems of the three CAN BUS protocols are called in sequence, 20 data stream contents are sent to the EMS system of the current vehicle, and if the 20 data stream commands of the diagnostic system of which CAN BUS protocol all receive positive response replies and the replied data stream values are all in the correct range, the EMS system assembled on the vehicle type is the diagnostic system of the CAN BUS protocol. By analogy, all systems such as a TCU system, an ABS system and the like can be identified. By using the scheme, the electric control system of the current automobile assembly can be effectively identified, and a user is helped to accurately select the most suitable diagnosis system to carry out diagnosis function operation on the automobile.
The vehicle diagnosis device in the embodiment of the application can automatically adopt one of preset communication protocols to send a diagnosis request command to the electric control system to be tested, if a first response message sent by the electric control system to be tested is received, the current communication protocol is determined to be a target communication protocol adopted by the electric control system to be tested, a group of preset data flow commands are sent to the electric control system to be tested by adopting the target communication protocol, a second response message sent by the electric control system to be tested is received, whether the second response message meets a preset condition or not is judged, and if the second response message meets the preset condition, the target diagnosis system corresponding to the group of preset data flow commands used currently is determined to be matched with the electric control system to be tested. The vehicle diagnosis equipment in the embodiment of the application can automatically match the corresponding diagnosis system for the electric control system to be tested, so that the diagnosis efficiency is improved, and the user experience is improved.
On the basis of the embodiment shown in fig. 1, in order to improve the efficiency of automatic matching of the automobile diagnosis system, the embodiment of the application adopts the vehicle identification code of the vehicle to screen the communication protocol or the preset data stream command set.

201. sending a diagnosis request command to the electronic control system to be tested by adopting one of preset communication protocols, and if receiving a first response message sent by the electronic control system to be tested, determining that the current communication protocol is a target communication protocol adopted by the electronic control system to be tested;
202. acquiring a vehicle identification code of a target vehicle, and determining a target set formed by all diagnosis systems corresponding to the vehicle identification code according to a preset mapping relation;
in practical application, the same type of electric control system of each manufacturer may be multiple, and multiple electric control systems correspond to multiple diagnosis systems. The mapping relation between a manufacturer and various diagnosis systems of the same type of electric control system of the manufacturer can be pre-established, after the vehicle identification code (VIN code) of the target vehicle is obtained, the manufacturer to which the target vehicle belongs can be identified according to the vehicle identification code, and then the target set formed by all diagnosis systems corresponding to the vehicle identification code is determined according to the preset mapping relation, and the diagnosis systems corresponding to other manufacturers are not needed to be adopted for matching in the matching process, so that the number of the diagnosis systems needing to be matched and verified is greatly reduced, and the matching and verifying efficiency is improved.
For example, there are 10 car factories, each manufacturer has 10 EMS systems, and in the embodiment of the present application, the vehicle diagnostic device may directly match and test 100 models of diagnostic systems, and preferably, after identifying the manufacturer based on the VIN code, only 10 models of diagnostic systems may be tested, so that the matching verification efficiency is improved.
203. Adopting a preset data stream command corresponding to one diagnostic system in the target set as a group of preset data stream commands to send to the tested electronic control system;
after the target communication protocol adopted by the electric control system to be tested is determined, the electric control system to be tested can be communicated with. In the embodiment of the application, a preset data stream command corresponding to one diagnostic system in a target set can be used as a group of preset data stream commands to be sent to the electric control system to be tested, a second response message sent by the electric control system to be tested is received, and the diagnostic system matched with the electric control system to be tested is determined according to the second response message.
204. Sending a group of preset data stream commands to the electric control system to be tested by adopting a target communication protocol, and receiving a second response message sent by the electric control system to be tested;
205. and judging whether the second response message meets a preset condition, and if so, determining that a target diagnosis system corresponding to a group of preset data stream commands currently used is matched with the electric control system to be tested.
The contents described in steps 201, 204, and 205 in this embodiment of the application are similar to the contents described in the above-mentioned steps 101 to 103, and are not described herein again specifically.
It should be understood that, in the various embodiments of the present application, the sequence numbers of the above steps do not mean the execution sequence, and the execution sequence of the steps should be determined by their functions and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
For the convenience of understanding, the automatic matching method of the automobile diagnosis system in the embodiment of the present application will be described below with reference to a specific application example.
1. The process begins by calling all the assembled engine systems (e.g., table one) of the vehicle manufacturer in turn to send a diagnosis request command, such as a 1001 enter command, to the current vehicle. If the request command sent by a called system is the response reply command, it indicates that the current automobile is equipped with the engine system of the protocol (for example, the current automobile type is judged to be equipped with the CAN protocol engine system).
