In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
The application provides a method for generating driving data in a simulation mode, which is mainly used for a simulation terminal, wherein the simulation terminal at least comprises a simulation control processor, and driving data meeting requirements can be generated in a simulation mode according to simulation generation conditions set on an operation interface by a user and a change rule acquired from a background system.
Example one
Fig. 1 is a schematic flowchart of a method for generating driving data through simulation according to an embodiment of the present application, where an execution subject of the method may be a simulation terminal, and the method includes the following steps:
s101: a simulation request of a user is received.
The driving data refers to data actually generated by the vehicle in the driving process, and includes but is not limited to state data and fault data of the vehicle; the simulation request includes, but is not limited to, a simulation time period, a type of parameter to be simulated, and a value range of each parameter.
It should be noted that the above-mentioned parameter types to be simulated include, but are not limited to, vehicle speed, remaining oil amount, water temperature, air flow, rotation speed of wheels, state of safety belt, state of door and window; the value ranges include the minimum value and the maximum value of each parameter.
In addition, the simulation time periods and the value ranges can be multiple, for example, the whole process from ignition starting to flameout parking of the vehicle can be divided into multiple simulation time periods.
S102: and respectively obtaining the change rule of each parameter in the corresponding value range.
It should be noted that, for a certain vehicle, the value of each parameter is not constant from ignition start to ignition off. Therefore, in order to ensure that the driving data generated by simulation is close to the actual driving data to the maximum extent, the variation rule of each parameter in the corresponding value range is acquired in advance before the corresponding driving data is generated according to the simulation request of the user.
In one embodiment, the change rule may be obtained through a big data platform.
It should be understood that, when the simulation request includes a plurality of simulation time periods and corresponding value ranges, the change rules that are satisfied when the parameter changes from the minimum value in the value range to the maximum value in the value range in each simulation time period may be obtained, and then the change rules are combined accordingly, so as to obtain the change rule in a longer simulation time period (for example, from ignition start to flameout process).
S103: and correspondingly generating simulation data of each parameter in the simulation time period according to the acquired change rule.
Since the driving data usually includes the variation values of various parameters of the vehicle during driving. Therefore, after the simulation data of each parameter is generated in the simulation time period, the driving data in the application is generated accordingly.
Therefore, in the embodiment of the application, the simulated driving data close to the actual driving data CAN be obtained on the premise of not depending on any CAN tool and vehicle-mounted equipment, so that the possibility of obtaining the driving data through manual intervention is reduced, and the testing efficiency and accuracy are improved; in addition, because the CAN tool and the vehicle-mounted terminal do not need to be familiar in advance, the requirements on testing personnel are reduced, and the method has strong usability and practicability.
Example two
Fig. 2 is a schematic flow chart of a method for generating driving data through simulation provided in an embodiment two of the present application, which is a further detailed and explanatory view of step S102 in the embodiment one, where an execution subject of the method may be a simulation terminal, and the method includes the following steps:

Wherein the attribute information includes but is not limited to a serial number of the in-vehicle terminal to be simulated.
Because the parameter change rules of each vehicle are not completely the same, before the change rule of each parameter in the corresponding value range is searched, the vehicle type information to be simulated needs to be determined, so that the driving data generated by simulation has higher authenticity.
It should be noted that, after being used for the first time, the vehicle-mounted terminal is usually bound with a certain vehicle, so as to implement a function dedicated for a special vehicle. Therefore, the type of the vehicle to be simulated can be obtained by searching the vehicle type information matched with the vehicle-mounted terminal.
In one embodiment, the vehicle types include, but are not limited to, cars, MPVs, vans, and passenger cars.
In one embodiment, after receiving the simulation request of the user, the method further comprises:
judging whether the simulation request contains a request for triggering alarm or not;
if the request of triggering the alarm is included, searching a triggering alarm condition corresponding to each parameter from a preset database;
judging whether the generated analog data meet corresponding triggering alarm conditions;
and if the corresponding triggering alarm condition is met, generating a corresponding alarm event.
S203: and correspondingly generating simulation data of each parameter in the simulation time period according to the acquired change rule.
In one embodiment, if the type of the parameter is a speed, obtaining a speed at each moment in the simulation time period according to an obtained speed change rule, and correspondingly generating speed simulation data according to the speed at each moment.
S204: and establishing communication connection with a server through a preset IP and a port, and sending the generated simulation data to the server through the established communication connection so as to instruct the server to perform test analysis according to the simulation data.
In one embodiment, a communication connection may be established with the server according to a preset domain name and port.

In one embodiment, the server may be an application server of some kind.
In one embodiment, the server may establish a communication connection with a client in advance so as to send the received simulation data to the client to instruct the client to perform test analysis of the vehicle according to the simulation data.
In one embodiment, the communication connection between the server and the client can be established by referring to the way the server establishes the communication connection with the preset simulation system.
In one embodiment, the server may parse and process the received simulation data into a format of a chart or a graph, and then send the processed simulation data to the client, so that the client may directly display the simulation data on the display interface after receiving the simulation data.
In one embodiment, to prevent information leakage, the server may encrypt the received analog data and then send the encrypted analog data to the client after receiving the analog data.
In one embodiment, the analog terminal may process the analog data generated in step S202 into data suitable for transmission in advance according to the type of transmission protocol supported by the established communication connection, so as to facilitate the server to receive and analyze the data.
In one embodiment, the server may parse the received analog data according to a predetermined protocol, such as: the analysis is performed according to the private protocol or the ministerial protocol of the communication department JT/T905.
In one embodiment, the server may perform corresponding storage after parsing the received simulation data.
S205: and receiving a message containing the test result returned by the server.
Wherein the test result comprises test success and test failure.
It should be understood that when the client is selected to perform the test analysis, the test result returned by the server is actually the test result returned by the client.
In one embodiment, the simulation terminal can adjust driving data generated by simulation in time when receiving a test failure message returned by the server, so as to ensure smooth test operation.
For convenience of explanation, the above steps will be explained only by taking the vehicle speed data in the simulation of the driving data as an example. When the vehicle speed at each moment in a time period of 0-t1 generated by simulation is less than 40km/h and the vehicle speed at each moment in a time period of t1-t2 is kept between 40km/h and 110km/h, and after a request of gradually decelerating and stopping the vehicle after the time period of t2 is received, whether a request of triggering an alarm is received or not is detected, if the user request is detected to generate a rapid acceleration alarm event and an overspeed alarm event in the time period of t1-t2, attribute information of a vehicle-mounted terminal to be simulated is obtained, corresponding adaptive vehicle type information is searched through the obtained attribute information, the vehicle speed change rule of the vehicle in the historical driving process and the conditions of the rapid acceleration alarm event and the overspeed alarm event in the time period of t1-t2 are searched through a large data platform, and if the vehicle speed change rule of the vehicle is inquired to be linearly increased in the time period of 0-t1, randomly changing within the time period t1-t2 and reaching 100km/h within a short time of the vehicle speed can trigger a rapid acceleration alarm event and keeping between 100km/h-110km/h within a long time of the vehicle speed can trigger a overspeed alarm event, linearly decreasing after the time t2, obtaining the speed of each moment in the simulation time period according to the obtained change rule, correspondingly generating simulation data of the speed of each moment according to the speed of each moment, generating a rapid acceleration alarm event when the rapid change of the data is detected to be 100km/h, and finally, sending the group of data to a server which establishes communication connection in advance for corresponding test analysis, and receiving a message which contains a test result and is returned by the server.
Therefore, compared with the first embodiment, the second embodiment of the application provides a specific implementation mode for obtaining the change rule of each parameter in the corresponding value range, so that the driving data generated by simulation can be closer to the real driving data, and the method has strong usability and practicability.
