Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of vehicle simulation testing, and in particular, to a vehicle simulation testing device, method, electronic equipment, storage medium and vehicle. Background Art

[0002] As the number of cars increases, people are increasingly dependent on cars as an efficient means of transportation for daily travel. In addition to paying more attention to hardware conditions such as car power and appearance, users are also paying more and more attention to the stability of the car's central control. At present, central control manufacturers generally use Monkey stress testing to verify the stability of the car's central control.

[0003] However, traditional Monkey stress testing only focuses on user behavior, for example, most of them use ADB commands to simulate user clicks, slides, simulated key presses and other events. But for the car's central control, it is far from enough to only focus on user behavior, because the car's mobility is strong, so the changes in the car's external environment are relatively complex, and the migration of the external environment will cause changes in the network environment of the car's central control. Therefore, the traditional Monkey stress testing solution only focuses on a single operating scenario of user behavior and is difficult to meet the multi-dimensional testing requirements of the stability of the car's central control. This leads to the traditional Monkey stress test at least unable to fully verify the stability of the car's central control in different network environments, at least there are problems such as insufficient verification, incomplete testing, and inaccurate results.

[0004] It should be noted that the aforementioned ADB is the abbreviation of Android Debug Bridge, which is translated as Android Debug Bridge. Summary of the invention

[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0037] It should be particularly noted that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.

[0038] Figure 1 Schematic diagram of a vehicle simulation test device provided by an embodiment of the present invention. This embodiment can be applied to any type of vehicle control simulation test scenario, such as automobiles, tricycles, motorcycles, electric vehicles, etc. The device can be implemented in software and / or hardware. Figure 1As shown, the vehicle simulation test device provided in this embodiment establishes a connection with the vehicle to be tested; the vehicle simulation test device at least includes a scenario simulation thread module, a Monkey execution thread module and a control module.

[0039] The scenario simulation thread module is connected to the control module and is at least used to receive the scenario simulation instructions issued by the control module during the simulation test process to simulate at least one network environment under the actual vehicle working condition according to the scenario simulation instructions.

[0040] The Monkey execution thread module is connected to the control module and is at least used to receive the Monkey test instructions issued by the control module during the simulation test, so as to control the vehicle computer under test to perform random simulation of user operations in at least one network environment under actual vehicle working conditions according to the Monkey test instructions until the simulation test is completed.

[0041] The control module is at least used to generate a simulation test report and save a simulation test log according to the random simulation actions and action execution results performed by the vehicle computer to be tested on user operations in each network environment under actual vehicle working conditions during the simulation test.

[0042] The vehicle machine to be tested may specifically refer to the central control system of the vehicle to be tested, and the vehicle machine to be tested may include, for example, a central control large screen, a cockpit domain controller, etc. In addition, the connection between the vehicle simulation test device and the vehicle machine to be tested may be a wired connection established through a network cable or optical fiber, or a wireless connection established based on WiFi, Bluetooth, etc.

[0043] It is known that the control module can adopt terminals such as single-chip microcomputers, industrial computers, and computers. In a specific embodiment, the control module can be, for example, a microcomputer motherboard based on ARM (Advanced RISC Machine) (such as Raspberry Pi), and the control module can use a secure digital card (such as an SD card, MicroSD card, etc.) as a memory hard disk. There are 1 / 2 / 4 Universal Serial Bus (USB) interfaces and a 10 / 100 Ethernet interface (Type A has no network port) around the card motherboard, which can not only connect a keyboard, a mouse, and a network cable, but also has a TV output interface for video analog signals and a high-definition multimedia interface (HDMI); all of the above components are integrated on a motherboard that is only slightly larger than a credit card, and have all the basic functions of a personal computer (PC). Just connect a display (such as a TV) and a keyboard to execute functions such as spreadsheets, word processing, and playing high-definition videos. It is understandable that the scene simulation instructions and Monkey test instructions can be multi-binary instructions issued by the Raspberry Pi.

[0044] In a specific implementation, the scenario simulation thread module can use ATC (Augmented Traffic Control). ATC is a tool for simulating network conditions and is also a project that allows users to control the connection between devices and the Internet. ATC can simulate different network conditions, for example, it can control multiple network factors such as bandwidth, delay, packet loss, packet damage, packet reordering, etc. ATC can run on a gateway, which can control the network of devices such as mobile phones connected to the network. ATC has a World Wide Web (Web) interface, and ATC can switch different network conditions through the Web interface. Since ATC uses Iptables and Tc internally, it only supports the Linux platform (Raspberry Pi is essentially a simple Linux computer).

[0045] It can be known that the random simulation actions performed by the user operation can be, for example, the action of clicking the navigation application icon on the central control screen, the event of sliding the browser search page displayed on the central control screen, the virtual key action of entering the contact's mobile phone number in the call interface of the central control screen, etc. In addition, the simulation test report can include the action execution results generated during any round of simulation test (for example, which functions of the vehicle to be tested have no response, crash and other test problems in which network environment, which functions have passed the test without problems), retest suggestions and other information after the completion of any round of simulation test; the simulation test log can refer to a text document that records the execution times, test times and other information of different vehicle to be tested function tests in different network environments during any round of simulation test.

[0046] In summary, this embodiment provides a vehicle simulation test device. First, the scenario simulation thread module receives the scenario simulation instruction issued by the control module during the simulation test, so as to simulate at least one network environment under the actual vehicle working condition according to the scenario simulation instruction; then, the Monkey execution thread module receives the Monkey test instruction issued by the control module during the simulation test, so as to control the vehicle machine to be tested to perform random simulation of user operations in at least one network environment under the actual vehicle working condition according to the Monkey test instruction until the simulation test is completed; finally, the control module generates a simulation test report and saves the simulation test log according to the random simulation actions and action execution results of the vehicle machine to be tested on the user operations in each network environment under the actual vehicle working condition during the simulation test.

[0047] In view of this, this embodiment can simulate at least one network environment under the actual vehicle working condition through the scene simulation field module during the simulation test of the automobile central control, and then use the Monkey execution thread module to control the vehicle machine to be tested to randomly simulate user operations in the corresponding network environment under different actual vehicle working conditions. In other words, this embodiment measures the stability of the vehicle machine to be tested from the dual perspectives of user behavior and network environment changes, which is closer to the actual vehicle operation scenario, and overcomes the existing Monkey stress test for automobile testing, which only focuses on a single operation scenario of user behavior, but is difficult to meet the multi-dimensional testing requirements of the stability of the automobile central control and has problems such as insufficient verification, incomplete testing, and inaccurate results, thereby improving the verification adequacy, comprehensiveness of testing, and accuracy of results of the vehicle control simulation test.

[0048] It should be noted that, in addition to the vehicle central control simulation test scenario, the technical solution of the embodiment of the present invention can be but is not limited to being adapted to the simulation test scenarios of various mobile terminals (such as mobile phones, computers, etc.) (correspondingly, the Monkey execution thread module controls the mobile terminal to be tested to perform random simulation of user operations in at least one network environment under actual working conditions according to the Monkey test instructions) to expand the stability test dimension of the mobile terminal, which is conducive to improving the performance of the mobile terminal in different network scenarios. I will not go into details.

[0049] In the above-mentioned embodiments or implementations, the specific method of the scene simulation thread module simulating at least one network environment under the actual vehicle working condition is described below, but it does not limit the present invention. In a specific implementation, optionally, the scene simulation thread module is at least specifically used to parse out the network environment allocation parameters according to the scene simulation instruction, and then simulate at least one network environment under the actual vehicle working condition based on the network environment allocation parameters.

[0050] In another specific implementation, optionally, the scenario simulation thread module simulates at least one network environment under the actual vehicle working condition based on the network environment allocation parameters, including at least:

[0051] The scenario simulation thread module simulates at least one network environment under actual vehicle operating conditions by allocating network uplink bandwidth, network downlink bandwidth, network uplink packet loss rate, network downlink packet loss rate, network uplink delay, network downlink delay and / or domain name resolution server delay.

[0052] In another specific embodiment, optionally, the network environment under actual vehicle operating conditions includes at least one of: an intermittent network environment under actual vehicle high-speed driving conditions, a short-term network disconnection environment under actual vehicle tunnel driving conditions, a 2G or 3G network environment under actual vehicle operating conditions in the field, and a weak network environment under actual vehicle operating conditions in an underground garage.

[0053] The network environment adjustment parameters include at least network uplink bandwidth, network downlink bandwidth, network uplink packet loss rate, network downlink packet loss rate, network uplink delay, network downlink delay and / or domain name resolution server (Domain Name System, DNS) delay.

[0054] Specifically, assuming that the network environment allocation parameters include network uplink bandwidth, network downlink bandwidth, network uplink packet loss rate, network downlink packet loss rate, network uplink delay, network downlink delay and DNS delay, Table 1 is a network environment parameter table provided by an embodiment of the present invention.

[0055] Table 1

[0056]

[0057] See Table 1. The uplink / downlink bandwidth in Table 1 refers to the aforementioned network uplink bandwidth and network downlink bandwidth; the uplink / downlink packet loss rate in Table 1 refers to the aforementioned network uplink packet loss rate and network downlink packet loss rate; the uplink / downlink delay in Table 1 refers to the aforementioned network uplink delay and network downlink delay.

[0058] Continuing to refer to Table 1, the intermittent network environment under the actual vehicle high-speed driving condition can be used to simulate the intermittent network environment of the vehicle to be tested when the vehicle is driving on the highway. At this time, the scenario simulation thread module can select the corresponding parameter configuration (that is, the network environment allocation parameters corresponding to the intermittent network environment under the actual vehicle high-speed driving condition) from various network environments (such as 2G, 3G, 4G, no network, high packet loss rate environment, etc.) shown in Table 1 according to random time intervals (the random time intervals can be equal time intervals or unequal time intervals) to construct the intermittent network environment under the actual vehicle high-speed driving condition.

[0059] Continuing to refer to Table 1, the short-term network disconnection environment under the actual vehicle tunnel driving condition can be used to simulate the environment where the vehicle under test is in a short period of time without network availability when the vehicle is driving in the tunnel. At this time, the scenario simulation thread module can randomly disconnect the network for a period of time at any time, for example, it can restore the network after a random time of 10s to 1000s of network disconnection. The restored network can select the corresponding parameter configuration (that is, the network environment allocation parameters corresponding to the short-term network disconnection environment under the actual vehicle tunnel driving condition) from other network environments (such as 2G, 3G, 4G, high packet loss rate environment, etc.) shown in Table 1 except for no network, and finally realize the construction of the short-term network disconnection environment under the actual vehicle tunnel driving condition.

[0060] Continuing to refer to Table 1, the 2G or 3G network environment under the field vehicle working condition can be used to simulate the 2G or 3G weak network environment of the vehicle under test when the vehicle is driving in the suburbs, rural areas and other field environments. At this time, the scenario simulation thread module can select the corresponding parameter configuration (that is, the network environment allocation parameters corresponding to the 2G or 3G network environment under the field vehicle working condition) from the 2G or 3G network environment shown in Table 1 to realize the construction of the 2G or 3G network environment under the field vehicle working condition.

[0061] Continuing to refer to Table 1, the weak network environment under the actual working condition of the underground garage can be used to simulate the weak network environment of the vehicle to be tested when the vehicle is driving or parking in the underground garage. At this time, the scene simulation thread module can select the corresponding parameter configuration (that is, the network environment allocation parameters corresponding to the weak network environment under the actual working condition of the underground garage) from the network environment with high uplink latency or high uplink packet loss or high downlink latency or high downlink packet loss characteristics shown in Table 1 [such as low packet loss rate, high latency environment (uplink), low packet loss rate, high latency environment (downlink), low packet loss rate, high latency environment, high packet loss rate environment (uplink), high packet loss rate environment (downlink), high packet loss rate environment] to realize the construction of the weak network environment under the actual working condition of the underground garage.

[0062] In summary, this embodiment can simulate at least one network environment under the actual vehicle working condition through the scene simulation field module during the simulation test of the automobile central control, and then use the Monkey execution thread module to control the vehicle machine to be tested to randomly simulate user operations in the corresponding network environment under different actual vehicle working conditions. In other words, this embodiment can measure the stability of the vehicle machine to be tested from the dual perspectives of user behavior and network environment changes, which is closer to the actual vehicle operation scenario, and overcomes the existing Monkey stress test for automobile testing, which only focuses on a single operation scenario of user behavior, but is difficult to meet the multi-dimensional testing requirements of the stability of the automobile central control and has problems such as insufficient verification, incomplete testing, and inaccurate results, thereby improving the verification adequacy, comprehensiveness of testing, and accuracy of results of vehicle control simulation testing.
