Description

Technical Field

[0001] The invention specifically relates to a guidance device for testing the risk avoidance capability of a vehicle and a guidance debugging method thereof. Background Art

[0002] The moose test is a commonly used international project to test the risk avoidance ability of vehicles. It was first created in Sweden. The method is to enter the test area at a constant speed when the vehicle is fully loaded (four passengers, and the luggage compartment is loaded with corresponding weights), and dodge at high speed without braking or accelerating. The two testers in the front two seats repeatedly increase the speed of the vehicle, record the speed at the time when it reaches the out-of-control state, and verify it twice to determine the reliability of the out-of-control speed value. It should also be added that the speed of the test is mainly based on the speedometer of the vehicle itself. In the moose test, the vehicle needs to be carried out in an unloaded state. During the test, the vehicle enters the test area at a constant speed, changes lanes urgently to avoid obstacles after discovering them, and does not perform any acceleration or braking operations during the process, and only passes by adjusting the direction. The final score is based on the speed of the vehicle passing without knocking down any piles. The higher the speed, the better the score. Generally speaking, a vehicle speed of 70 to 79 km / h is considered good, and over 80 km / h is considered excellent. In the elk test route, the pile barrel is frequently knocked over. After the pile barrel leaves its original position, it needs to be quickly reset for the next test. However, there is a lack of a unified reset method and standardized quantitative processing method, resulting in low reset accuracy, which affects the accuracy of the test results, especially on gravel, ice and snow covered road conditions, the reset accuracy is lower and it takes longer.

[0011] A guidance and debugging method for vehicle risk avoidance capability test is implemented by using the above-mentioned guidance device for vehicle risk avoidance capability test. The guidance and debugging method for vehicle risk avoidance capability test is as follows: after pile barrels are placed according to the formation form and size requirements, a corresponding number of guidance devices for vehicle risk avoidance capability test are selected for deployment, each second light beam guidance plate in the guidance device for vehicle risk avoidance capability test is adjusted, and multiple second light beam guidance plates are respectively moved to their respective predetermined positions to ensure that the light beam of each second light beam guidance plate is irradiated to the top, bottom or other predetermined position of a corresponding pile barrel.

[0013] 2. The multi-point indicator in the present invention is divided into two structural forms. The first is a same-drive multi-point indicator. Multiple first light beam guide plates drive the multi-track guide shaft through the first drive member to form a self-rotation motion so as to move up and down on the two guide rails.

[0030] Specific implementation method six: Fig.11 , Fig.12 , Fig.13 and Fig.14 The present embodiment is described. The guiding device for testing the risk avoidance capability of a vehicle in the present embodiment is a single device that can partially adjust the position of an emitted light beam, and specifically comprises a base 1, a lifting support rod 2 and a multi-point indicator 3. The base 1 is horizontally arranged, and the lifting support rod 2 is vertically arranged on the base 1. The lower end of the lifting support rod 2 is connected to the base 1, and the upper end of the lifting support rod 2 is provided with a multi-point indicator 3; the multi-point indicator 3 is an heterogeneous multi-point indicator, and the multi-point indicator 3 comprises a double-track support frame 3-1 and a plurality of second light beam guiding plates 3-2, and the plurality of second light beam guiding plates 3-2 reciprocate along the length direction of the double-track support frame 3-1, and each second light beam guiding plate 3-2 is a self-driven light beam guiding plate, and each second light beam guiding plate 3-2 is a self-driven light beam guiding plate. The two-beam guiding plate 3-2 includes a supporting frame 3-2-1, a second light source 3-2-2, two second driving members 3-2-3 and two gears 3-2-4. The supporting frame 3-2-1 is mounted on the double-track supporting frame 3-1. The two gears 3-2-4 are arranged in parallel in the supporting frame 3-2-1. Each gear 3-2-4 is correspondingly provided with a second driving member 3-2-3. The front side of the supporting frame 3-2-1 is hinged with the second light source 3-2-2. The back side of the supporting frame 3-2-1 is provided with two second driving members 3-2-3 in parallel. The power output shaft of each second driving member 3-2-3 passes through the supporting frame 3-2-1 and is connected to its corresponding gear 3-2-4. Each gear 3-2-4 is meshed with the double-track supporting frame 3-1.

[0031] In this embodiment, the front side of the support frame 3-2-1 is hinged with the second light source 3-2-2, and the lamp body of the second light source 3-2-2 is connected to the support frame 3-2-1 via an existing spherical hinge seat to achieve multi-position swing of the lamp body.

[0032] Furthermore, the difference between the heterogeneous drive multi-point indicator and the homogeneous drive multi-point indicator is that the second light beam guide plate 3-2 in the heterogeneous drive multi-point indicator drives each gear 3-2-4 to move up and down on the double-track support frame 3-1 through each second drive member 3-2-3, and can independently drive each second light beam guide plate 3-2.

The above two guiding devices can guide the pile bucket 11 to quickly return to its original position, which is beneficial to improve the test accuracy and the uniform standardization of the layout route, and is suitable for large-scale sports games or other rapid response related tests.

[0033] Specific implementation method seven: Combination Figures 1 to 10 , Figures 15 to 18The figure shows the present embodiment. The present embodiment is used for the guidance and debugging method of the vehicle risk avoidance ability test. After placing the pile buckets 11 in accordance with the formation form and size requirements, a corresponding number of guidance devices for the vehicle risk avoidance ability test are selected for deployment. The specific deployment process is: the standard formation is divided into two groups, that is, the pile buckets 11 corresponding to each side of the car are a group, each group of pile buckets 11 corresponds to a guidance device for the vehicle risk avoidance ability test, the distance value between two adjacent pile buckets 11 in the formation is obtained, and the angle between the top or bottom of each pile bucket 11 and the position of the first light source 8-2 in the corresponding first light beam guiding plate 8 is derived using the trigonometric function formula. The vertical distance where the first light source 8-2 is located, the vertical position is the distance from the first light source 8-2 to the bottom of the base 1, that is, the sum of the height of the base 1, the height of the lifting support rod 2 after adjustment, and the length from the top of the lifting support rod 2 to the first light source 8-2. After obtaining the distance from each first light source 8-2 to the bottom of the base 1 one by one, drive the first driving member 5 to synchronously adjust each first light beam guiding plate 8 until each first light source 8-2 moves to a predetermined position, and the predetermined position is the vertical position of the first light source 8-2, which is the distance from it to the bottom of the base 1 to ensure that the light emitted by the first light source 8-2 is irradiated to the predetermined position of the corresponding pile bucket 11. Similarly, adjust the vertical position of each first light source 8-2 in the guidance device for the vehicle risk avoidance ability test corresponding to another group of pile buckets 11, and the horizontal distance between the two groups of pile buckets 11 is the horizontal distance between the two guidance devices for adjusting the vehicle risk avoidance ability test.

[0034] In this embodiment, the guidance device for adjusting the vehicle's risk avoidance ability test can correspond to guiding a variety of different formations, or it can correspond to guiding only one formation. It can also combine multiple guidance devices for adjusting the vehicle's risk avoidance ability test and use them simultaneously to form a large-span or other complex formation arrangement.

[0035] After adjusting each first light beam guiding plate 8 in the vehicle hazard avoidance ability test guiding device, multiple first light beam guiding plates 8 are synchronously moved to the predetermined position to ensure that the light beam of each first light beam guiding plate 8 is irradiated to the top, bottom or other predetermined position of a corresponding pile bucket 11. When the vehicle is started to perform the elk test, when it is found that a local pile bucket 11 has deviated from the original position, the position of the pile bucket 11 is rearranged based on the position of the light beam emitted by the first light beam guiding plate 8 corresponding to the pile bucket 11. The placement principle is to ensure that the light beam of the first light beam guiding plate 8 is re-irradiated to the bottom of the pile bucket 11, thereby realizing the operation process of accurately and quickly rearranging the pile bucket 11.

[0036] The guidance device for testing the risk avoidance ability of a vehicle involved in the implementation of the present method is a guidance device for testing the risk avoidance ability of a same-drive vehicle, specifically comprising a base 1, a lifting support rod 2 and a multi-point indicator 3, wherein the base 1 is arranged horizontally, the lifting support rod 2 is vertically arranged on the base 1, the lower end of the lifting support rod 2 is connected to the base 1, and the upper end of the lifting support rod 2 is provided with a multi-point indicator 3; the multi-point indicator 3 is a same-drive multi-point indicator, and the multi-point indicator 3 comprises a main support plate 4, a first driving member 5, a multi-track guide shaft 6, two guide rails 7 and a plurality of first light beam guiding plates 8, the main support plate 4 is vertically arranged on the lifting support rod 2, the lower end of the main support plate 4 is connected to the lifting support The upper end of the support rod 2 is detachably connected, and two guide rails 7 are arranged side by side on the main support plate 4 along the length direction of the main support plate 4. The multi-track guide shaft 6 is arranged between the two guide rails 7. A plurality of track grooves 10 are processed on the multi-track guide shaft 6. The upper end of the multi-track guide shaft 6 passes through the top of the main support plate 4 and is connected to the first driving member 5. The lower end of the multi-track guide shaft 6 is hinged to the bottom of the main support plate 4. A plurality of first light beam guiding plates 8 are sleeved between the two guide rails 7 along the length direction of the main support plate 4. The back side of each first light beam guiding plate 8 is hinged to a track groove 10 in the multi-track guide shaft 6. Each first light beam guiding plate 8 reciprocates between the two guide rails 7 driven by the rotation of the multi-track guide shaft 6.

[0037] Furthermore, the multi-point indicator 3 is a same-drive multi-point indicator. The first driving member 5 on the multi-point indicator 3 drives the multi-track guide shaft 6 to rotate, and the sliding column 8-3 drives the first light beam guiding plate 8 to slide along the multiple track grooves 10 on the multi-track guide shaft 6, so that the first light beam guiding plate 8 moves up and down on the two guide rails 7 through at least one first slider 8-4 and at least one second slider 8-5, thereby ensuring that the light beam of the first light beam guiding plate 8 is accurately irradiated on the top, bottom or other predetermined positions of the pile barrel 11.

[0038] Specific implementation method eight: Combination Figures 11 to 18As shown in the figure, the guidance and debugging method of the vehicle risk avoidance ability test is to place the pile buckets 11 according to the formation form and size requirements, select the corresponding number of guidance devices for the vehicle risk avoidance ability test for deployment, adjust each second light beam guidance plate 3-2 in the guidance device for the vehicle risk avoidance ability test, and move multiple second light beam guidance plates 3-2 to their respective predetermined positions to ensure that the light beam of each second light beam guidance plate 3-2 is irradiated to the top, bottom or other predetermined positions of a corresponding pile bucket 11. When the vehicle is started to perform the elk test, when it is found that a local pile bucket 11 has deviated from its original position, the position of the pile bucket 11 is rearranged based on the position of the light beam emitted by the second light beam guidance plate 3-2 corresponding to the pile bucket 11. The placement principle is to ensure that the light beam of the second light beam guidance plate 3-2 is re-irradiated to the top, bottom or other predetermined positions of the pile bucket 11, thereby realizing the operation process of accurately and quickly re-arranging the pile bucket 11.

[0039] The specific process of selecting a corresponding number of guidance devices for testing the risk avoidance ability of vehicles for deployment is as follows: the standard formation is divided into two groups, that is, the pile buckets 11 corresponding to each side of the car are one group, each group of pile buckets 11 corresponds to a guidance device for testing the risk avoidance ability of vehicles, and the distance value between two adjacent pile buckets 11 in the formation is obtained. According to the angle between the top or bottom of each pile bucket 11 and the position of the second light source 3-2-2 in the corresponding second light beam guiding plate 3-2, the vertical distance of the second light source 3-2-2 is derived using a trigonometric function formula. The vertical position is the distance from the second light source 3-2-2 to the bottom of the base 1. The distance, i.e. the sum of the height of the base 1, the height of the lifting support rod 2 after adjustment, and the length from the top of the lifting support rod 2 to the second light source 3-2-2, is obtained one by one. After the distance from each second light source 3-2-2 to the bottom of the base 1, each second driving member 3-2-3 is driven to synchronously or asynchronously adjust each second light beam guiding plate 3-2 until each second light source 3-2-2 moves to a predetermined position, which is the vertical position of the second light source 3-2-2. The distance from the bottom of the base 1 can ensure that the light emitted by the second light source 3-2-2 is irradiated to the predetermined position of the corresponding pile bucket 11. Similarly, the vertical position of each second light source 3-2-2 in the guiding device for the vehicle risk avoidance ability test corresponding to another group of pile buckets 11 is adjusted.

[0040] In this embodiment, the guidance device for adjusting the vehicle's risk avoidance ability test can correspond to guiding a variety of different formations, or it can correspond to guiding only one formation. It can also combine multiple guidance devices for adjusting the vehicle's risk avoidance ability test and use them simultaneously to form a large-span or other complex formation arrangement.

[0041] During the implementation of this method, the guidance device involved in the vehicle avoidance ability test is a single device that can partially adjust the position of the emitted light beam, specifically including a base 1, a lifting support rod 2 and a multi-point indicator 3, the base 1 is horizontally arranged, the lifting support rod 2 is vertically arranged on the base 1, the lower end of the lifting support rod 2 is connected to the base 1, and the upper end of the lifting support rod 2 is provided with a multi-point indicator 3; the multi-point indicator 3 is a heterogeneous drive multi-point indicator, the multi-point indicator 3 includes a double-track support frame 3-1 and a plurality of second light beam guiding plates 3-2, the plurality of second light beam guiding plates 3-2 reciprocate along the length direction of the double-track support frame 3-1, each second light beam guiding plate 3-2 is a self-driven light beam guiding plate, and each second The beam guiding plate 3-2 includes a support frame 3-2-1, a second light source 3-2-2, two second driving members 3-2-3 and two gears 3-2-4. The support frame 3-2-1 is mounted on the double-track support frame 3-1. The two gears 3-2-4 are arranged in parallel in the support frame 3-2-1. Each gear 3-2-4 is correspondingly provided with a second driving member 3-2-3. The front side of the support frame 3-2-1 is hinged with the second light source 3-2-2. The back side of the support frame 3-2-1 is provided with two second driving members 3-2-3 in parallel. The power output shaft of each second driving member 3-2-3 passes through the support frame 3-2-1 and is connected to its corresponding gear 3-2-4. Each gear 3-2-4 is meshed with the double-track support frame 3-1.

[0042] Furthermore, the multi-point indicator 3 is a heterogeneous drive multi-point indicator, wherein the second light beam guiding plate 3-2 is a self-driven light beam guiding plate, and the two second driving members 3-2-3 on the second light beam guiding plate 3-2 drive the two gears 3-2-4 to move up and down on the double-track support frame 3-1, thereby ensuring that the light beam of each second light beam guiding plate 3-2 is irradiated to the top, bottom or other predetermined position of a corresponding pile bucket 11. During the process of starting the vehicle for the moose test, if it is found that the pile bucket 11 is partially deviated from its original position, the position of the pile bucket 11 can be restored to its original position based on the position of the light beam emitted by the second light beam guiding plate 3-2 corresponding to the pile bucket 11.

[0043] When the present invention is used in a special-shaped or large-span formation, the position of the pile bucket 11 can be guided by increasing the number of guiding devices or opening the light beam guiding plates at appropriate positions.

[0044] Working process of the present invention: When the first form of the multi-point indicator 3 is a same-drive multi-point indicator: first, the staff places the base 1 of the guidance device for testing the vehicle's risk avoidance ability on the ground, and then uses the lifting support rod 2 to extend the device to the specified height, and starts the first driving member 5 on the multi-point indicator 3. The first driving member 5 drives the multi-track guide shaft 6 to rotate on the main support plate 4, so that the multiple track grooves 10 on the multi-track guide shaft 6 drive the multiple first light beam guiding plates 8 to move back and forth between the two guide rails 7, so that the light beam of the first light beam guiding plate 8 is irradiated on the top, bottom or other predetermined positions of the corresponding pile bucket 11, and then the vehicle is started for the moose test. During the test, if the pile bucket 11 is offset, the staff can quickly restore the pile bucket 11 to its original position through the guidance of the light beam of the first light beam guiding plate 8.

[0045] When the second form of the multi-point indicator 3 is a heterodyne multi-point indicator: first, the staff places the base 1 of the guidance device for testing the vehicle's risk avoidance ability on the ground, and then uses the lifting support rod 2 to extend the device to a specified height, and starts the two second driving members 3-2-3 on the multi-point indicator 3. The two second driving members 3-2-3 drive the two gears 3-2-4 to reciprocate on the double-track support frame 3-1, wherein the two second driving members 3-2-3, the two gears 3-2-4, and the double-track support frame 3-1 are installed on the support frame 3-2-1, and the second light beam guiding plate 3-2 is installed on the support frame 3-2-1, and its working principle is the same as that of the first form.
