Description

Technical Field

[0001] This disclosure relates to the field of vehicle testing technology, and in particular to vehicle testing methods, apparatus, electronic equipment and computer program products. Background Technology

[0002] In the current booming field of intelligent driving technology, the required functions are increasing daily, and the technology iteration cycle is becoming shorter. When using actual vehicle road verification methods for vehicle testing, the scale of vehicles, venues, and manpower required is large. Furthermore, due to the extreme difficulty in determining boundary conditions, testing the vehicle's rotational conditions results in long testing cycles and high costs. Using pure software virtual simulation for vehicle testing can reduce costs to some extent, but because software testing is too theoretical, the results of pure software virtual simulation tests have significant errors compared to the results of actual road verification.

[0003] Therefore, obtaining more accurate vehicle testing results at a lower cost is a pressing issue that needs to be addressed. Currently, no effective solution has been proposed to address this problem. Summary of the Invention

[0004] This disclosure provides a vehicle testing method, apparatus, electronic device, and computer program product to at least solve the technical problem of inaccurate vehicle test results in the prior art.

[0005] According to one embodiment of this disclosure, a vehicle testing method is provided, comprising: controlling a vehicle under test to move along a first trajectory, wherein the vehicle under test is used to acquire driving information of a preset vehicle, and the driving information is used to simulate the driving state of the preset vehicle; in response to the vehicle under test moving to a first target position on the first trajectory, detecting the rotation condition of the vehicle under test, wherein the rotation condition is the condition of a first target component of the vehicle under test when the vehicle under test is in a simulated driving state; and controlling the driving state of a virtual vehicle in a virtual scene based on the rotation condition.

[0006] According to one embodiment of this disclosure, a vehicle testing device is also provided, comprising: a first control module, configured to control a vehicle under test to move along a first trajectory, wherein the vehicle under test is configured to acquire driving information of a preset vehicle, the driving information being used to simulate the driving state of the preset vehicle; a detection module, configured to detect the rotation condition of the vehicle under test in response to the vehicle under test moving to a first target position on the first trajectory, wherein the rotation condition is the condition of a first target component of the vehicle under test when the vehicle under test is in a simulated driving state; and a second control module, configured to control the driving state of a virtual vehicle in a virtual scene based on the rotation condition.

[0009] According to one embodiment of this disclosure, a computer program product is also provided, including a computer program that is executed by a processor using the vehicle testing method proposed in this disclosure.

[0010] In the embodiments of this disclosure, the vehicle under test is controlled to move along a first trajectory to a first target position, and the rotation condition of the vehicle under test is detected. Based on the rotation condition, the driving state of a virtual vehicle in a virtual scene is controlled. The vehicle under test is used to acquire driving information of a preset vehicle, and this driving information is used to simulate the driving state of the preset vehicle. The rotation condition refers to the condition of the first target component of the vehicle under test when it is in the simulated driving state.

Compared with the actual road vehicle testing in the prior art, the method in this embodiment effectively reduces the costs of venue, manpower, and equipment. Furthermore, the rotation condition detected when the vehicle under test is in a driving state is more accurate than the results of virtual software simulation testing. In other words, the method in this embodiment solves the technical problems of high vehicle testing costs and inaccurate test results in the prior art by controlling the vehicle under test to simulate the driving state of a preset vehicle and detecting the rotation condition of the vehicle under test in the simulated driving state, achieving more efficient vehicle testing and more accurate vehicle testing results.

[0024] It should be noted here that, in some optional embodiments, the above... Figure 1 The electronic device shown may include hardware elements (including circuitry), software elements (including computer code stored on a computer-readable medium), or a combination of both hardware and software elements. It should be noted that... Figure 1 This is only one instance of a specific particular example, and is intended to illustrate the types of components that may exist in the aforementioned electronic devices.

[0025] Under the aforementioned operating environment, this disclosure provides, for example... Figure 2 The test method for the vehicle shown can be performed by... Figure 1 The computer terminal or similar electronic device shown is used for execution. Figure 2 This is a flowchart of a vehicle testing method according to an embodiment of the present disclosure. Figure 2 As shown, the method may include the following steps:

[0026] Step S20: Control the vehicle under test to move along the first trajectory, wherein the vehicle under test is used to acquire the driving information of the preset vehicle, and the driving information is used to simulate the driving state of the preset vehicle.

[0027] Optionally, the driving information of the preset vehicle may include information such as the driving speed, acceleration, deceleration, turning distance, and torque of the preset vehicle in various driving states on the real road (such as uphill, downhill, turning, emergency stop, rapid acceleration, and rapid deceleration). The vehicle under test simulates the driving state of the preset vehicle based on the driving information, and it is possible to measure whether the performance of the wheels of the vehicle under test is normal in various driving states. This is convenient for subsequent improvement and analysis of the vehicle under test. For example, when the vehicle under test is set to uphill, the wheel speed at which the vehicle under test can successfully achieve uphill operation can be tested and then applied to the automatic speed control of subsequent intelligent driving vehicles.

[0028] Step S22: In response to the vehicle under test moving to the first target position on the first trajectory, the rotation condition of the vehicle under test is detected, wherein the rotation condition is the condition of the first target component of the vehicle under test when the vehicle under test is in a simulated driving state.

[0029] In step S22, the test vehicle is detected when it is in the first target position. That is to say, the rotation condition of the test vehicle can be detected while it is stationary. Compared with the actual road test method in the prior art, the test process in this embodiment is simpler and less costly.

[0030] Step S24: Based on the rotational conditions, control the driving state of the virtual vehicle in the virtual scene.

[0031] In other words, the obtained wheel speed and wheel steering angle can be used as reference data for subsequent virtual experience design. Taking a virtual driving experience game as an example, based on the wheel speed and wheel steering angle obtained from the test under various driving conditions, the driving state of the virtual vehicle in the virtual scene can be set. For example, when the virtual vehicle is triggered to go uphill, the speed of the virtual vehicle can be increased to the speed set for going uphill.

[0032] In the embodiments of this disclosure, the vehicle under test is controlled to move along a first trajectory to a first target position, and the rotation condition of the vehicle under test is detected. Based on the rotation condition, the driving state of a virtual vehicle in a virtual scene is controlled. The vehicle under test is used to acquire driving information of a preset vehicle, and this driving information is used to simulate the driving state of the preset vehicle. The rotation condition refers to the condition of the first target component of the vehicle under test when it is in the simulated driving state. In this embodiment, the vehicle under test at the first target position simulates the driving state of a preset vehicle, and the rotation condition of the vehicle under test in the simulated driving state is detected. The vehicle under test can be tested in an indoor environment. Compared with the actual road vehicle testing in the prior art, the method in this embodiment effectively reduces the costs of venue, manpower, and equipment. Furthermore, the rotation condition detected when the vehicle under test is in a driving state is more accurate than the results of virtual software simulation testing. In other words, the method in this embodiment solves the technical problems of high vehicle testing costs and inaccurate test results in the prior art by controlling the vehicle under test to simulate the driving state of a preset vehicle and detecting the rotation condition of the vehicle under test in the simulated driving state, achieving more efficient vehicle testing and more accurate vehicle testing results.

[0033] The method described in this embodiment will be further described below.

[0034] As an optional implementation, step S22, detecting the rotational condition of the vehicle under test, further includes the following method steps:

[0035] Step S221: Detect the position information of the first target component of the vehicle under test; in response to determining the second target position of the first target component through the position information of the first target component, obtain the rotation condition.

[0036] The location information of the first target component is detected and the location information of the first target component is used to determine the location of the second target component, so that the first target component is located in an accurate detection position, thereby improving the accuracy of the detection results.

[0037] In step S221, the first target component can be the vehicle's wheels and brake discs. The operating conditions of the first target component can be wheel speed, wheel steering angle, brake disc speed, brake disc steering angle, etc. Based on the rotational operating conditions, other vehicle information can also be obtained, such as wheel torque information, rapid acceleration information, rapid deceleration information, rotation distance information, and rotational torque information.

[0038] As an optional implementation, in step S221, the first target component includes the wheels of the vehicle under test, and detecting the rotational condition of the vehicle under test includes:

[0039] Step S2210: Detect the first position information of the wheel within the target area, wherein the target area is the area enclosed by the bearing inner ring of the target detection device; in response to determining that the wheel is located at a third target position through the first position information, inflate the inner tube of the wheel to obtain a rotational condition.

[0040] In step S2210, the target detection device is connected to the vehicle under test. When the vehicle under test is simulating the driving state of a preset vehicle, the target detection device can detect the rotation condition of the target component. Specifically, the rotation condition can include information such as the number of wheel rotations, rotation speed, and rotation duration.

[0041] Optionally, the first position information of the wheel in the target area can be used to characterize the coincidence of the geometric center of the wheel and the geometric center of the bearing inner ring. When the wheel is in the third target position, the geometric center of the wheel coincides with the geometric center of the bearing inner ring, so that the tension force of the inner tube in all directions is uniform when the inner tube is inflated. After inflation, the wheel can fit against the bearing inner ring, and the bearing inner ring can apply uniform pressure to the wheel in all directions, so as to achieve a tight connection between the wheel and the bearing inner ring.

[0042] In step S2210, after the inner tube of the wheel is inflated, the tire is securely connected to the inner ring of the bearing. When the test vehicle is running, the rotation of the wheel can drive the inner ring of the bearing to rotate relative to the outer ring of the bearing, thereby converting the rotational speed of the wheel into the rotational speed of the inner ring of the bearing. At this time, the rotational speed of the wheel can be obtained by detecting the rotational speed of the inner ring of the bearing. For example, the target detection device includes a detection element connected to the inner ring of the bearing. The number of rotations and rotation duration of the inner ring of the bearing are detected by the detection element (e.g., sensor, encoder, etc.). The number of rotations, rotational speed, rotation duration, and other information of the wheel can be obtained by analysis and calculation.

[0043] As an optional implementation, in step S221, the first target component includes the wheels of the vehicle under test, and detecting the rotational condition of the vehicle under test includes:

[0044] Step S2211: Detect the second position information of the wheel of the vehicle under test within the target area, wherein the target area is the area enclosed by the inner ring of the bearing of the target detection device;

[0045] In step S2211, the target detection device may further include a detection element connected to the inner ring of the bearing. When the vehicle under test is in a simulated driving state of a preset vehicle, the rotation of the wheel drives the inner ring of the bearing to rotate. The rotation condition of the wheel can be obtained by detecting the number of rotations and the rotation duration of the inner ring of the bearing through the detection element. Specifically, the rotation condition may include information such as the number of rotations, rotation speed, and rotation duration of the wheel.

[0046] Step S2212: In response to determining that the wheel is located at the fourth target position through the second position information, the second target component of the target detection device is controlled to start inflating, and the rotation condition is acquired when the second target component meets the target state, wherein the second target component is the tensioning member of the locking mechanism of the target detection device.

[0047] The second position information can be used to characterize the degree of coincidence between the geometric center of the wheel and the geometric center of the tensioner and the inner ring of the bearing. When the wheel is in the fourth target position, the geometric center of the wheel can coincide with the geometric center of the tensioner and the inner ring of the bearing, so that the tensioner can apply uniform pressure to the wheel in multiple directions after inflation. The wheel can be fastened to the inner ring of the bearing through the tensioner, and the rotation of the wheel can drive the tensioner and the inner ring of the bearing to rotate synchronously.

[0048] In step S2212, a tensioner is used for inflation and deflation. Different sizes of tensioners can be selected based on the tire size and model, allowing the target detection equipment to be applied to various vehicle models. Simultaneously, the tensioner reduces damage to the tire during the inflation and deflation process. Preferably, the tensioner is annular and located on the surface of the inner ring of the bearing. The target state of the second target component is tensioned. When the second target component is tensioned, the tensioner is completely in contact with the outer tire of the wheel, and the tensioner applies pressure to the wheel to ensure a stable connection between the wheel and the target detection equipment.

[0049] As an optional implementation, in step S221, the first target component includes the brake disc of the vehicle under test, and detecting the rotational condition of the vehicle under test includes:

[0050] Step S2213: Detect the third position information of the brake disc within the target area, wherein the target area is the area enclosed by the inner ring of the bearing of the target detection device;

[0051] Step S2214: In response to determining that the brake disc is located at the fifth target position through the third position information, the rotation condition is obtained.

[0052] In this embodiment, the wheels are disassembled and the brake discs are connected to the target detection equipment. This allows the wheels to be removed for separate testing when the clearance between the wheel arch and the tire of the vehicle under test is too small to be directly tested as a whole vehicle. This effectively improves the practicality of the vehicle testing method disclosed herein.

[0053] It should be noted that steps S2210 to S2214, as different embodiments in this application, are applicable to different testing environments. For example, when the target detection device is connected to the wheel of the vehicle under test, steps S2210 to S2212 can be applied to perform vehicle performance testing without disassembling the wheel. When the entire vehicle cannot be tested directly due to vehicle model issues, steps S2213 to S2214 can be applied to test the brake disc separately by disassembling the wheel and connecting the target detection device to the brake disc. The above embodiments make the vehicle testing method adaptable to various types of vehicles.

[0054] In the embodiments of this disclosure, in order to simultaneously detect wheel speed and wheel steering angle, the target detection device further includes a steering angle detection element, a fixed part, and a rotating part. The bearing of the target detection device is fastened to the rotating part, and the rotating part is rotatably connected to the fixed part. The steering angle detection element is disposed on the rotating part, and the fixed part is fixedly connected to a reference surface such as the ground or a detection platform. When the wheel turns, it drives the bearing to turn, so that the rotating part turns synchronously. At this time, the steering angle detection element can detect the rotation angle and rotation duration of the rotating part, thereby obtaining the wheel steering angle, steering speed, etc.

[0055] In the method disclosed in the above embodiments, the vehicle to be tested located at the first target position is connected to the target detection device, which can simultaneously detect the wheel speed and steering angle. Compared with the speed measuring platform and dynamometer in the prior art that only support wheel speed detection, more vehicle parameters can be measured in this embodiment. Compared with the method of using external special tooling for vehicle testing in the prior art, the testing method in this embodiment is simpler and uses less manpower and material resources.

[0056] As an optional implementation, the following steps are included before step S22:

[0057] Step S210: Obtain the wheelbase information of the vehicle to be tested;

[0058] Step S211: Based on the wheel track information, control the first and second guide rails of the target support equipment to move to the avoidance position so that the vehicle under test can move to the first target position.

[0059] Combining steps S210 and S211, the first guide rail and the second guide rail move to the avoidance position. When the vehicle under test moves along the first trajectory, at least part of the first trajectory is formed by the first guide rail and the second guide rail. That is, the vehicle under test moves along the first guide rail and the second guide rail to the first target position. The first guide rail and the second guide rail have different avoidance positions according to the wheel track of different vehicles under test, which makes the method of this disclosure applicable to more vehicle models with different wheel track.

[0060] As an optional implementation, the following steps are included before step S22:

[0061] Step S212: Obtain the wheelbase information of the vehicle to be tested;

[0062] Step S213: Based on the wheelbase information, control the movement of the third and fourth guide rails of the target support device;

[0063] In step S214, in response to the third and fourth guide rails moving to a position matching the wheelbase of the vehicle under test, the target detection device is controlled to move along the second trajectory to the first target position to detect the rotational condition of the vehicle under test.

[0064] It should be noted that there are multiple ways to connect the target detection device and the target support device in this embodiment, and there are multiple corresponding second trajectories. For example, when the target detection device is slidably connected to the first guide rail and the second guide rail, the second trajectory of the target detection device is a trajectory that slides along the wheelbase direction of the vehicle. When the target detection device is slidably connected to the third guide rail and the fourth guide rail, the second trajectory of the target detection device is a trajectory that slides along the wheel track direction of the vehicle.

[0065] By combining steps S212 to S214, the third and fourth guide rails are moved to different positions according to the wheelbase of different vehicles under test, which can adapt to the wheelbase of different vehicles under test.

[0066] As an optional implementation, the target support device also includes a lifting mechanism. In step S214, before controlling the target detection device to move along the second trajectory to the first target position, the method further includes: determining that the vehicle to be tested is located at the first target position, controlling the lifting mechanism to drive the vehicle to be tested to a preset height in the vertical direction, and then controlling the target detection device to move along the second trajectory to the first target position.

[0067] In this embodiment, the inner ring of the bearing of the target detection device is a certain distance away from the target support device. A lifting mechanism is set to raise the vehicle to be tested, so that the first target component can be more easily matched and connected with the inner ring of the bearing.

[0068] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of this disclosure, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a terminal device, such as a mobile phone, computer, server, or network device, to execute the methods of the various embodiments of this disclosure.

As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the apparatus described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0073] The second control module 304 is used to control the driving state of the virtual vehicle in the virtual scene based on the rotation condition.

Based on the rotational condition, the driving state of the virtual vehicle in a virtual scene is controlled. The vehicle under test is used to acquire driving information of a preset vehicle, and this driving information is used to simulate the driving state of the preset vehicle.
