Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the drawings in the embodiments of the present application, and 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 invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the voltage value at the current moment can be displayed in a vehicle diagnosis software interface, but the function of judging whether the voltage value at the current moment is normal is not available, and in the long-time vehicle diagnosis process, if the voltage value is low, a plurality of diagnosis functions can be failed to execute, and even various fault codes can be reported without any reason.
For this purpose, the application correspondingly provides a vehicle diagnosis scheme which can finish vehicle diagnosis under the condition of low voltage value.
Referring to fig. 1, an embodiment of the present application discloses a vehicle diagnosis method, including:
step S11: and acquiring a voltage value of the target vehicle at the current time, and judging whether the voltage value at the current time is smaller than a first preset voltage threshold value or not.
In this embodiment, it is understood that the first preset voltage threshold may be preset based on the diagnosis of the target function, if the target function to be diagnosed is more or more complex, the preset voltage threshold may be set to be higher, for example, 14V, and if the target function to be diagnosed is simpler, the preset voltage threshold may be set to be lower, for example, 11V. The voltage value at the current time is compared with the first preset voltage threshold value to determine whether the voltage value at the current time can meet the voltage value required by the target function diagnosis, so that the probability of completing the target function diagnosis is improved.
Step S12: and if the voltage value at the current time is smaller than the first preset voltage threshold value, starting an engine of the target vehicle.
If the voltage value at the current moment is smaller than the first preset voltage threshold value, the fact that the electric quantity of the current vehicle is difficult to support the subsequent diagnosis tasks is indicated, and the fact that certain diagnosis tasks cannot be completed due to too low voltage is quite likely to cause diagnosis failure, so that if the current voltage value is smaller than the first preset voltage threshold value, the engine is started to charge the vehicle.
Step S13: and stopping the engine when the voltage value of the target vehicle is detected to be larger than a second preset voltage threshold value, and performing target function diagnosis on the target vehicle.
In this embodiment, during the operation of the engine, the battery of the target vehicle is charged during the operation of the engine, and when the voltage value of the target vehicle is detected to be greater than the second preset voltage threshold, the operation of the engine is stopped, and the battery power can meet the battery power required for diagnosing the vehicle, where the second preset voltage threshold can also be set based on the target function required for diagnosing. In some embodiments, the second preset voltage threshold may also be the same as the first preset voltage threshold.
As can be seen, the method includes the steps that firstly, a voltage value of a target vehicle at a current time is obtained, and whether the voltage value at the current time is smaller than a first preset voltage threshold value or not is judged; if the voltage value at the current time is smaller than the first preset voltage threshold value, starting an engine of the target vehicle; and stopping the engine when the voltage value of the target vehicle is detected to be larger than a second preset voltage threshold value, and performing target function diagnosis on the target vehicle. Therefore, whether the voltage value at the current moment can support the subsequent vehicle diagnosis is judged by comparing whether the voltage value at the current moment is smaller than a first preset voltage threshold value or not; if the voltage value at the current moment is smaller than a first preset voltage threshold value, starting the engine, and completing the charging task of the target vehicle in the running process of the engine, so that the voltage value can be increased; when the voltage value of the target vehicle is detected to be larger than the second preset voltage threshold value, the target vehicle is enabled to obtain enough voltage to support completion of target function diagnosis, and the engine operation is stopped, so that the situation that the vehicle diagnosis fails due to the fact that the voltage value at the current moment is too low is avoided.
Referring to fig. 2, an embodiment of the present application discloses a specific vehicle diagnosis method, including:
step S21: and acquiring at least one instruction information of original factory data, maintenance experience, customer feedback and online data corresponding to the vehicles of at least one vehicle type, and creating an instruction information base based on the instruction information so as to acquire an engine starting instruction and an engine stopping instruction of the target vehicle from the instruction information base.
In this embodiment, when it is subsequently determined that the voltage value of the target vehicle at the current time is smaller than the first preset voltage threshold, the engine of the target vehicle needs to be started, it may be understood that an engine start instruction is required when the engine is started, so that an instruction information base may be created, so that when an engine start instruction and an engine stop instruction are required, a related instruction may be obtained from the instruction information base, and it should be noted that the instruction information base may be created based on different vehicle type information.
Step S22: and acquiring a voltage value of the target vehicle at the current time, and judging whether the voltage value at the current time is smaller than a first preset voltage threshold value or not.
In this embodiment, the first preset voltage threshold may be set based on the vehicle diagnosis situation, for example, the first preset voltage threshold is set to 11V, and if the voltage value of the target vehicle at the current time is 13V, the voltage value at the current time is greater than the first preset voltage threshold, so that the vehicle diagnosis may be performed; if the voltage value of the target vehicle at the current time is 9V, the voltage value at the current time is smaller than the first preset voltage threshold, so that the subsequent engine starting step is required.
Step S23: if the voltage value at the current time is smaller than the preset voltage threshold, acquiring the model information of the target vehicle, acquiring an engine starting instruction corresponding to the model information from the instruction information base, and sending the engine starting instruction to an engine of the target vehicle so as to start the engine.
In this embodiment, if the voltage value at the current time is smaller than the preset voltage threshold, it is indicated that the voltage value at the current time cannot support to complete the target function diagnosis, and therefore the target vehicle needs to be charged, so that the vehicle type information of the target vehicle is acquired first, an engine starting instruction corresponding to the vehicle type information is acquired from the instruction information base, and then the engine starting instruction is sent to the engine so as to start the engine, thereby achieving the purpose of charging the target vehicle. It can be appreciated that if the engine start instruction is not acquired, the first preset prompt message may be displayed through the first preset window. For example, if the engine start instruction is not acquired, a first preset prompt message for representing the instruction acquisition failure is displayed through a center console or an instrument panel of the target vehicle, so that a user can perform related processing based on the first preset prompt message, and vehicle diagnosis failure is avoided.
Step S24: when the voltage value of the target vehicle is detected to be larger than a second preset voltage threshold value, the engine stop instruction corresponding to the vehicle type information is acquired so as to stop the engine operation, and target function diagnosis is carried out on the target vehicle.
Therefore, the method and the device can judge whether the voltage value at the current time is smaller than the preset voltage threshold value or not, and if the voltage value is smaller than the first preset voltage threshold value, the battery of the target vehicle needs to be charged, so that the engine is started, the battery of the target vehicle is charged, the purpose of improving the voltage is achieved, and further the target function diagnosis is supported. Before starting the engine operation, a command information base is constructed based on the model information of each vehicle so as to acquire corresponding commands based on the model information of different target vehicles, enabling the engine operation to be started and the engine operation to be stopped.
Referring to fig. 3, an embodiment of the present application discloses a specific vehicle diagnosis method, including:
step S31: and acquiring a voltage value of the target vehicle at the current time, and judging whether the voltage value at the current time is smaller than a first preset voltage threshold value or not.
Step S32: and if the voltage value at the current time is smaller than the first preset voltage threshold value, starting an engine of the target vehicle.
In this embodiment, before starting the engine of the target vehicle, the method further includes: acquiring the vehicle type information of the target vehicle; an engine start command and an engine stop command are acquired based on the vehicle type information so as to start the engine using the engine start command and stop the engine operation using the engine stop command.
In this embodiment, the process of obtaining the engine start instruction and the engine stop instruction further includes: and if the engine starting instruction and/or the engine stopping instruction are not acquired, displaying a first preset prompt message. It can be understood that the first preset prompting message may be "no target instruction is obtained", or "no target instruction is queried," and whether to query the instruction is confirmed, so as to prompt the user whether the instruction to be obtained is correct.
Step S33: and during the starting period of the engine, judging whether the target function meets the preset execution condition or not, and correspondingly prompting according to a judging result.
In the present embodiment, diagnostic functions that can be executed during the engine start-up, such as a read version information function, a read data stream function, a read trouble code function, and a first preset action test function, may be preset, or diagnostic functions that cannot be executed during the engine start-up, such as a clear trouble code function, a preset special function, and a second preset action test function, may be preset. It should be noted that when the target function cannot be executed, the target function that cannot be executed may be directly masked from the interface, for example, a first icon of the function that can be executed and a second icon corresponding to the function that cannot be executed may be displayed differently, and the second icon may be grayed out or may not be displayed directly.
In this embodiment, it is determined whether the target function is any one or more of a version information reading function, a data stream reading function, a fault code reading function, and a first preset action test function; and if the target function is judged to be any one or more of a version information reading function, a data stream reading function, a fault code reading function and a first preset action test function, executing the target function. For example, the target function is a fast test function, and the fast test function belongs to a first preset action test function, so that the fast test function meets a preset execution condition, and the target function is executed.
In this embodiment, the method further includes: during the starting of the engine, if an instruction for executing a target function sent by a user is detected, judging whether the target function meets a preset executing condition or not; if yes, executing the target function; if not, displaying a second preset prompt message.
In this embodiment, it is determined whether the target function is any one or more of a function of clearing a fault code, a preset special function, and a second preset action test function; if the target function is judged to be any one or more of a fault code clearing function, a preset special function and a second preset action test function, second preset prompt information can be displayed through a second preset window. For example, the second preset prompting information may be "the engine is running, the execution condition is not satisfied temporarily", so that the user obtains the second preset prompting information to stop the target function that does not satisfy the preset execution condition.
In this embodiment, the determining whether the target function meets a preset execution condition specifically includes: and acquiring the vehicle type information of the target vehicle, and judging whether the target function meets a preset execution condition or not based on the vehicle type information. It is understood that the diagnostic functions executable by different vehicle types during the engine start-up are different, so in this embodiment, the vehicle type information of the target vehicle is acquired before judging whether the target function satisfies the preset execution condition, so as to judge whether the target function satisfies the preset execution condition according to the vehicle type information.
Step S34: and stopping the engine when the voltage value of the target vehicle is detected to be larger than a second preset voltage threshold value, and performing target function diagnosis on the target vehicle.
Therefore, the purpose of charging the target vehicle with the voltage value smaller than the preset voltage threshold value is achieved through the preset period of engine operation, and further the purpose of improving the voltage value is achieved to support target function diagnosis of the target vehicle; during engine start, a target function satisfying a preset execution condition can be executed, improving diagnostic efficiency.

and the diagnosis module 13 is used for stopping the engine operation and performing target function diagnosis on the target vehicle when the voltage value of the target vehicle is detected to be larger than a second preset voltage threshold value.
As can be seen, the method includes the steps that firstly, a voltage value of a target vehicle at a current time is obtained, and whether the voltage value at the current time is smaller than a first preset voltage threshold value or not is judged; if the voltage value at the current time is smaller than the first preset voltage threshold value, starting an engine of the target vehicle; and stopping the engine when the voltage value of the target vehicle is detected to be larger than a second preset voltage threshold value, and performing target function diagnosis on the target vehicle. Therefore, whether the voltage value at the current moment can support the subsequent vehicle diagnosis is judged by comparing whether the voltage value at the current moment is smaller than a first preset voltage threshold value or not; if the voltage value at the current moment is smaller than a first preset voltage threshold value, starting the engine, and completing the charging task of the target vehicle in the running process of the engine, so that the voltage value can be increased; when the voltage value of the target vehicle is detected to be larger than the second preset voltage threshold value, the target vehicle is enabled to obtain enough voltage to support completion of target function diagnosis, and the engine operation is stopped, so that the situation that the vehicle diagnosis fails due to the fact that the voltage value at the current moment is too low is avoided.
