Description

Technical Field

[0001] The present invention relates to the technical field of automobile testing, and in particular to an automobile road testing system based on virtual reality and road test data processing. Background Art

[0002] Automotive testing technology is a skill that must be understood and mastered by those working in the automotive industry. The automotive road test course is a required practical course for students majoring in automotive engineering and other related fields. Automotive road testing requires professional testing sites, testing equipment, test vehicles, and professional automotive testers. Automotive colleges and universities, as well as automotive testing R&D departments, face the challenges of not only meeting the aforementioned testing conditions and favorable weather conditions, but also incurring high teaching or training costs. This is particularly true when conducting relevant tests in colleges and universities. Due to limitations in teaching conditions such as test sites, test equipment, and test hours, it's difficult to ensure students' in-depth participation in the tests. Most courses utilize demonstration experiments, resulting in suboptimal practical teaching results and difficulty in achieving teaching objectives.

[0003] There are two main technical routes for existing automobile virtual experiment platforms. One is pure software, which is directly installed on a computer or server. Trainees only use input devices such as a mouse and keyboard to set experimental parameters and observe experimental results, which has poor practicality. The other type uses simulated driving equipment such as simulated steering wheels, accelerators and brakes to simulate the test process, but it is difficult to simulate the driving experience of a real car. The test results do not match the driving process to a high degree, which cannot effectively train test personnel. In addition, when driving on a simulated road, it is impossible to feel the impact caused by the vehicle colliding with the road. Summary of the Invention

[0020] Beneficial effects

[0021] The invention provides an automobile road test system based on virtual reality and road test data processing.

[0022] Compared with the existing technology, it has the following beneficial effects:

[0023] 1. The automobile road test system based on virtual reality and road test data processing simulates a vehicle collision, so that the experimental operating table controls the air pump to blow air into the inner cavity of the trachea, and transports the gas to the inner cavity of the hollow tube through the connecting tube, and then starts the driving motor connected to the inner cavity of the shell, so that the output end of the driving motor drives the baffle to rotate through the first connecting rod, so that a gap appears between the surface of the baffle and the inner cavity of the hollow tube, so that the inflated gas pushes the third sliding rod to extend, and at the same time the second slider drives the second spring to follow and slide in the inner cavity of the second slide groove, and at the same time the first sealing ring and the second sealing ring realize the sealing function, so that the extrusion plate squeezes the second sliding rod, so that the second sliding rod slides in the inner cavity of the second sleeve, and the rubber sleeve hits the driving cabin, thereby solving the problem of not being able to feel the impact caused by the vehicle colliding with the road when driving on the simulated road.

[0024] 2. This automobile road test system based on virtual reality and road test data processing can simulate the realistic tilting and shaking caused by a vehicle collision by rotating the ball bearing on the fixed plate when the cockpit is hit, thereby driving the cockpit to expand and contract in the inner cavity of the first sliding rod and the first sleeve.

[0025] 3. The automobile road test system based on virtual reality and road test data processing adopts virtual test and simulation technology. It can conduct relevant automobile road tests indoors on a driving simulator without the need for professional automobile road test sites, test equipment, test vehicles and professional automobile test personnel. Since it is conducted indoors, it is not restricted by weather conditions, the test organization is flexible, and participants can participate in the test safely and in depth. There are no test-related test costs. At the same time, by changing the test vehicle and the test road mathematical model, automobile road virtual tests with various test vehicles and road conditions are carried out, and the test results are compared, which further improves the teaching effect of practical teaching or related technical training.

[0026] 4. The automobile road test system based on virtual reality and road test data processing can restore the test process of automobile road tests to the greatest extent by adopting a multi-freedom driving simulation cockpit. The steering wheel, accelerator and brake of the real vehicle ensure that the driving operation during the road test is the same as the actual test. The free driving cockpit can convert the accelerations in different directions received by the vehicle during the test into deflections of the seat in different directions and speeds in real time, simulating the actual driving experience. The driving operation of the test personnel can be reflected in the vehicle's driving data and driving experience through real-time calculations through the background mathematical model, which can simulate the test process and test results of automobile road tests in real time.

[0045] See also Figure 11 The cockpit 35 includes a freedom cockpit 351, a seat 352, a display 353, a steering wheel 354, an accelerator 355 and a brake 356.

[0046] S1. When in use, first open the rotating door 34 to allow the driver to get into the inner cavity of the freedom cockpit 351, and then let the driver sit on the seat 352 with the safety belt. At the same time, through the console 31, the changes in road conditions are simulated, which can maximize the restoration of the test process of the automobile road test and the tester's feelings, effectively improving the defect of the general virtual test process that the real feeling is not strong. Then, the steering wheel 354, accelerator 355 and brake 356 in the cockpit 35 can be used to change the real operations of steering, refueling and parking of the vehicle displayed on the console 31. During the driving process of the steering wheel 354, the rotation of the rotating component 37 can drive the six cylinders 38 to extend and retract, and the parameter information of the vehicle driving is transmitted to the MBOX drive. The driver conversion drives the electric motor to rotate and finally realizes the left and right flipping of the cockpit and the front and rear pitching, displacement, yaw and other actions, ensuring that the driving operation during the road test is the same as the actual test. The steering wheel 354 has a force feedback function, which can simulate the changes in the steering wheel assist torque during vehicle driving and the steering wheel force feedback when the road conditions change, solving the problem of lack of road feel during the virtual test. The tester inputs the driving operation conditions through the steering wheel 354, accelerator 355 and brake 356 in the cockpit 35. Through the background mathematical model and real-time calculation, the driving data such as the direction, speed and acceleration of the vehicle are obtained, which can simulate the test process and test results of the automobile road test in real time, solving the problem of mismatch between the virtual test results and the driving operation.

[0047] S2. When in use, the experimental console 1 includes a computer host, a monitor, a keyboard, a mouse and other hardware, which mainly realizes the functions of learning theoretical knowledge of test equipment and test process, virtual installation and setting of test equipment, setting of automobile road test conditions, obtaining test result data and evaluating and assessing the test process.

[0048] S3. During use, when the simulated vehicle collides on the right side, the console 31 transmits the information to the experimental operation table 1 through the server 2, and the experimental operation table 1 controls the air pump to blow air into the inner cavity of the air pipe 366, and transmits the gas to the inner cavity of the hollow tube 362 through the connecting tube 365, and then starts the driving motor 3672 in the inner cavity of the connecting shell 3671 on the right side, so that the output end of the driving motor 3672 drives the baffle 3675 to rotate through the first connecting rod 3673, so that a gap appears between the surface of the baffle 3675 and the inner cavity of the hollow tube 362, so that the inflated gas will push the third sliding rod 363 on the right to extend, and at the same time the second slider 3616 will drive the second spring 3617 to follow the inner cavity of the second slide groove 3618 When the first sliding rod 369 is pressed against the second sliding plate 3617, the second sliding rod 369 slides in the inner cavity of the second sleeve 3619, and the rubber sleeve 3610 hits the cockpit 35. At the same time, the first slider 3611 drives the first spring 3613 to follow and slide in the inner cavity of the first slide groove 3612. When the air is not inflated, the driving motor 3672 drives the baffle 3675 to reset, blocking the inner cavity of the hollow tube 362, so that the third sliding rod 363 loses its pushing force. Then, under the elastic force of the second spring 3617 and the first spring 3613, the hollow tube 362 and the second sliding rod 369 are respectively driven to reset.

[0049] S4. During use, when the cockpit 35 is hit, the ball 392 can rotate the fixed plate 391, thereby driving the cockpit 35 to drive the first sliding rod 393 and the inner cavity of the first sleeve 394 to expand and contract, so that the cockpit 35 can simulate the tilting and shaking caused by the vehicle collision when it is hit. When the impact force disappears, the elastic force of the third spring 395 will drive the first sliding rod 393 to return to its original position, thereby returning the cockpit 35 to its original position.

[0050] In addition, the server 2 is used to transmit the fuel consumption, emissions, torque, power, coolant, lubricating oil, temperature, and pressure performance values ​​in the driving simulator 3 to the experimental operating table 1 for parameter display, so that the driving status of the driving simulator 3 can be observed, and the impact device 36 can impact the corresponding position according to the impact conditions of the left and right ends of one side.
