Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0052] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the vehicle angle information measuring device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0053] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a vehicle angle information measurement program.

[0054] exist Figure 1 In the vehicle angle information measuring device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the vehicle angle information measuring device of the present invention can be set in the vehicle angle information measuring device. The vehicle angle information measuring device calls the vehicle angle information measuring program stored in the memory 1005 through the processor 1001 and executes the vehicle angle information measuring method provided in the embodiment of the present invention.

[0055] This invention provides a method for measuring vehicle angle information, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of a vehicle angle information measurement method according to the present invention.

[0056] In this embodiment, the vehicle angle information measurement method includes the following steps:

[0057] Step S10: Upon receiving the angle measurement command, control the vehicle under test to adjust to the angle test state.

[0058] It should be noted that this embodiment is applied when it is necessary to measure the included angle information of a vehicle under test (e.g., when it is necessary to test the approach angle or departure angle of a vehicle). It receives an included angle test command, controls the vehicle under test to adjust to the included angle test state, acquires the plumb bob measurement information and level measurement information of the vehicle under test in the included angle test state, determines the test point of the vehicle under test based on the plumb bob measurement information and the level measurement information, acquires the position information of the test point, and determines the included angle information between the vehicle under test and the ground based on the position information of the test point. Because this invention receives... When the angle measurement command is received, the vehicle under test is controlled to adjust to the angle test state to ensure that the vehicle under test is in a state that meets the angle test conditions, effectively avoiding errors in the angle test. The plumb bob measurement information and the level measurement information of the vehicle under test in the angle test state are obtained. The test point of the vehicle under test is determined based on the plumb bob measurement information and the level measurement information, thereby accurately locating the test point of the vehicle under test. Based on the position information of the test point, the angle information between the vehicle under test and the ground is determined, effectively avoiding measurement errors and improving the efficiency of angle information measurement.

[0059] Compared with the prior art, the present invention determines the test point of the vehicle under test based on the measurement information of the plumb bob and the measurement information of the level, thereby ensuring the accuracy of the selection of the test point of the vehicle under test, effectively avoiding the problem of error in the angle measurement caused by the deviation of the test point, obtaining the position information of the test point, and determining the angle information between the vehicle under test and the ground based on the position information of the test point, realizing the accurate measurement of the vehicle angle information and improving the efficiency of angle information measurement.

[0060] It should be understood that the execution subject of the method in this embodiment may be a vehicle angle information measuring device with data processing, network communication and program operation functions, such as a central controller, or other devices or equipment that can achieve the same or similar functions. Here, the above-mentioned vehicle angle information measuring device (hereinafter referred to as the angle measuring device) is used as an example for explanation.

[0061] It should be noted that the included angle measurement command can be a measurement command received when an included angle measurement is required. The included angle measurement can refer to the included angle of the vehicle under test, such as the approach angle or departure angle, measured by the included angle measurement device. The included angle test state can be a state in which the vehicle under test meets the included angle measurement standard. For example, the included angle test state can be a state in which the vehicle under test is fully loaded and stationary, and the tires are aligned and consistent.

[0062] It should be understood that, in order to effectively avoid errors in angle measurement and improve measurement accuracy, the angle measuring device in this embodiment controls the vehicle under test to adjust to the angle test state, i.e., the state that meets the angle measurement standard, when it receives the angle measurement command, so that the vehicle under test is in the state that meets the angle measurement standard.

[0063] For example, when the angle measuring device receives the departure angle measurement command, it controls the vehicle under test to adjust to a fully loaded and stationary state, with the tires aligned and maintaining the same direction for the angle test, to ensure the stability of the vehicle under test, effectively avoid the error of the angle measurement, and thus improve the accuracy of the departure angle measurement.

[0064] Step S20: Obtain the plumb bob measurement information and the level measurement information of the vehicle under test in the angle test state.

[0065] It should be noted that the plumb bob measurement information can be the measurement information of the vehicle under test obtained by the angle measuring device through the plumb bob, such as the tire distance from the ground or the distance from the vehicle body contact point to the ground. Similarly, the level measurement information can be the measurement information of the vehicle under test obtained by the angle measuring device through the level, such as the tangent information between the vehicle body contact point and the tire.

[0066] It should be understood that, in order to ensure the accuracy of the included angle test, the included angle measuring device in this embodiment uses a plumb bob and a level to measure the information of the vehicle under test, using the plumb bob measurement information and the level measurement information of the vehicle under test in the included angle test state.

[0067] Step S30: Determine the test point of the vehicle under test based on the measurement information of the plumb bob and the measurement information of the level.

[0068] It should be noted that the points to be measured can be the various measurement points corresponding to the vehicle under test. The angle measuring device can measure the angle information of the vehicle under test based on the various measurement points of the vehicle under test. For example, the angle measuring device can measure the wheel contact point, the near point of the vehicle body, etc., to obtain the angle information of the vehicle under test.

[0069] It should be understood that, in order to ensure the accuracy of the included angle information measurement, the included angle measuring device in this embodiment determines the measurement point of the vehicle under test based on the measurement information of the plumb bob and the measurement information of the level. Compared with the prior art, this embodiment ensures the accuracy of the selection of the measurement point corresponding to the vehicle under test, and effectively avoids the problem of error in the included angle information measurement caused by inaccurate selection of the measurement point.

[0070] In a specific implementation, when the included angle measuring device receives an included angle measurement command, it controls the vehicle under test to adjust to the included angle test state based on the included angle measurement command. Based on the included angle measurement command, it measures and marks the vehicle under test in the included angle test state using a plumb bob and a level, and obtains the plumb bob measurement information and the level measurement information of the vehicle under test in the included angle test state. Based on the plumb bob measurement information and the level measurement information, it determines the test point of the vehicle under test.

[0071] For example, when the angle measuring device receives the departure angle and approach angle measurement command, it controls the vehicle under test to adjust to the angle test state, that is, controls the vehicle under test to adjust to a fully loaded and stationary state with the vehicle tires aligned. The plumb bob is naturally lowered along the center of the wheel until it just touches the ground. At this point, the contact point between the center of the plumb bob and the ground is the center of the wheel. The center of the wheel is marked as the wheel contact point. The plumb bob is then pressed against the wheel contact points of the two tires on both sides of the vehicle under test. One end of the level is parallel and pressed against the plumb bob line, while the other end is slowly raised until it contacts the vehicle body. The point where the level contacts the vehicle body is marked as the vehicle body's near point. That is, the wheel contact point and the vehicle body's near point obtained by measuring and marking with the plumb bob and level are the test points.

[0072] Step S40: Obtain the location information of the point to be measured, and determine the angle information between the vehicle to be measured and the ground based on the location information of the point to be measured.

[0073] It should be noted that the location information of the test point can be the coordinate information of the test point corresponding to the test vehicle. For example, the location information of the test point can be the type information, quantity information, and coordinate information of each point in the test point. The aforementioned angle information can be related to the approach angle or departure angle between the test vehicle and the ground.

[0074] In a specific implementation, the angle measuring device acquires the position information of the point to be measured, determines the line length and spacing between each point to be measured corresponding to the vehicle to be measured based on the position information, and calculates the angle information between the vehicle to be measured and the ground based on the above line length and spacing using a preset angle formula.

[0075] Furthermore, in order to effectively determine the angle information between the vehicle under test and the ground based on the point to be measured, the above step S40 may include:

[0076] Obtain the location information of the point to be measured;

[0077] Draw the test line corresponding to the test point based on the location information of the test point;

[0078] Obtain the length of the line to be tested;

[0079] The angle between the vehicle under test and the ground is determined based on the line length and the location information of the point to be measured.

[0080] It should be noted that the line to be measured can be a line segment drawn based on the positional information of the point to be measured. For example, the line to be measured can be a line segment drawn based on the wheel contact point or a line segment drawn based on the near-ground mapping point. The angle measuring device can calculate the angle information between the vehicle under test and the ground based on the line length. The aforementioned line length can be the length of each line segment corresponding to the vehicle under test.

[0081] In a specific implementation, the angle measuring device acquires the position information of the point to be measured, connects the points to be measured according to the position information, draws the line to be measured corresponding to the point to be measured, acquires the line length of the line to be measured, and determines the angle information between the vehicle to be measured and the ground based on the line length and the position information of the point to be measured.

[0082] Furthermore, in order to accurately calculate the angle information between the vehicle under test and the ground, the above-mentioned determination of the angle information between the vehicle under test and the ground based on the line length and the position information of the point under test may include:

[0083] The distance between the vehicle's perimeter and the near-ground mapping point is determined based on the location information of the point to be measured.

[0084] The angle information between the vehicle under test and the ground is determined based on the spacing and the line length.

[0085] It should be noted that the spacing can be the distance between the vehicle's near point and the ground near point, because the ground near point is the point on the ground that is mapped from the vehicle's near point along the vertical direction. Therefore, the spacing can be the height of the vehicle's near point from the ground.

[0086] Further, determining the angle information between the vehicle under test and the ground based on the spacing and the line length includes:

[0087] Based on the spacing and the line length, the angle between the vehicle under test and the ground is obtained using a preset angle formula, wherein the preset angle formula is as follows:

[0088] φ = DEGREES(ATAN(H / L))

[0089] In the formula, φ is the angle between the vehicle under test and the ground, H is the distance, and L is the line length.

[0090] It should be noted that the preset angle formula can be a formula for calculating the departure angle and approach angle of the vehicle under test.

[0091] When calculating the approach angle, the preset angle formula is as follows, where φ1 is the approach angle of the vehicle under test, H1 is the distance between the front near point of the vehicle under test and the front near ground mapping point of the vehicle under test, and L1 is the distance between the front near ground mapping point of the vehicle under test and the line connecting the contact points of the front wheels on both sides of the vehicle under test.

[0092] φ1=DEGREES(ATAN(H1 / L1))

[0093] When calculating the departure angle, the preset included angle formula is as follows, where φ2 is the departure angle of the vehicle under test, H2 is the distance between the near point of the rear side of the vehicle under test and the near ground mapping point of the rear side of the vehicle under test, and L2 is the distance between the near ground mapping point of the rear side of the vehicle under test and the line connecting the contact points of the rear wheels on both sides of the vehicle under test.

[0094] φ2=DEGREES(ATAN(H2 / L2))

[0095] Reference Figure 3 , Figure 3 This is a schematic diagram showing the location distribution of each test point and test line in this embodiment. J1 is the contact point of the front left wheel of the vehicle under test, J2 is the contact point of the front right wheel of the vehicle under test, J3 is the contact point of the rear left wheel of the vehicle under test, J4 is the contact point of the rear right wheel of the vehicle under test, A1 is the front near-ground mapping point of the vehicle under test, A2 is the rear near-ground mapping point of the vehicle under test, B1 is the intersection of the line connecting A1 and A2 and the line connecting J1 and J2, and B2 is the intersection of the line connecting A1 and A2 and the line connecting J3 and J4.

[0096] This embodiment controls the vehicle under test to adjust to the angle testing state upon receiving an angle measurement command. It acquires the plumb bob and level measurements of the vehicle under test in this state, determines the test point based on the plumb bob and level measurements, obtains the position information of the test point, and determines the angle between the vehicle and the ground based on the position information of the test point. Because this invention controls the vehicle under test to adjust to the angle testing state upon receiving the angle measurement command, it ensures that the vehicle is in a state that meets the angle testing conditions, effectively avoiding errors in angle testing. It acquires the plumb bob and level measurements of the vehicle under test in this state, determines the test point based on the plumb bob and level measurements, and thus accurately locates the test point. Based on the position information of the test point, it determines the angle between the vehicle and the ground, achieving accurate measurement of vehicle angle information, effectively avoiding measurement errors, and improving the efficiency of angle information measurement.

[0097] refer to Figure 4 , Figure 4 This is a flowchart illustrating a second embodiment of a vehicle angle information measurement method according to the present invention.

[0098] Based on the first embodiment described above, in this embodiment, step S30 includes:

[0099] Step S301: Determine the wheel contact point of the vehicle under test based on the plumb bob measurement information.

[0100] It should be noted that the wheel contact point can be the contact point between the wheel of the vehicle under test and the ground, that is, the tangent point between the wheel and the ground, and the plumb bob measurement information can be the information obtained by the angle measuring device through the plumb bob measuring the vehicle under test.

[0101] In practice, the angle measuring device can be used to lower a plumb bob vertically along the center of the wheel until it contacts the ground. The point of contact between the bottom of the plumb bob and the ground is the wheel contact point. The wheel contact points include the front left wheel contact point, the rear left wheel contact point, the front right wheel contact point, and the rear right wheel contact point.

[0102] Step S302: Obtain the position information of the wheel contact point.

[0103] It should be noted that the position information of the wheel contact point may include the coordinate information, position marking information, or position distribution information of the wheel contact point. The angle measuring device can mark the position of the wheel contact point and determine the position distribution information of the wheel contact point based on the marked points.

[0104] Step S303: Determine the test point of the vehicle under test based on the measurement information of the plumb bob, the measurement information of the level, and the position information of the wheel contact point.

[0105] In practice, the angle measuring device determines the position information of the wheel contact point, the wheel center point, the vehicle perimeter, and the corresponding ground mapping point based on the plumb bob measurement information and the level measurement information to determine the test points of the vehicle under test.

[0106] This embodiment determines the wheel contact point of the vehicle under test based on the plumb bob measurement information, obtains the position information of the wheel contact point, and determines the test point of the vehicle under test based on the plumb bob measurement information, the level measurement information, and the position information of the wheel contact point. Because this invention determines the wheel contact point of the vehicle under test based on the plumb bob measurement information, it accurately marks the tangent point between the wheel and the ground. Then, it obtains the position information of the wheel contact point based on the marked point, and determines the test point of the vehicle under test based on the plumb bob measurement information, the level measurement information, and the position information of the wheel contact point. This ensures the accuracy of the test point corresponding to the vehicle under test and effectively avoids the problem of angle measurement errors caused by inaccurate selection of the test point.

[0107] refer to Figure 5 , Figure 5 This is a flowchart illustrating a third embodiment of a vehicle angle information measurement method according to the present invention.

[0108] Based on the second embodiment described above, in this embodiment, step S303 includes:

[0109] Step S313: Determine the near point of the vehicle body of the test vehicle based on the position information of the wheel contact point and the measurement information of the level.

[0110] Step S323: Obtain the location information of the vehicle's nearest point;

[0111] Step S333: Determine the test point of the vehicle under test based on the measurement information of the plumb bob, the position information of the wheel contact point, and the position information of the vehicle body perimeter.

[0112] It should be noted that the level measurement information can be obtained by using an angle measuring device to measure the vehicle under test through a level. The aforementioned vehicle perimeter can be the point where the extension line from the wheel contact point to the vehicle body first contacts the vehicle body. The vehicle perimeter can include the front perimeter and the rear perimeter. The location information of the aforementioned vehicle perimeter can include coordinate information, location marker information, or location distribution information, such as the vehicle perimeter's location on the vehicle body and its location relative to the ground.

[0113] In practice, the angle measuring device determines the positions of the wheel contact points on both sides of the vehicle under test based on the position information of the wheel contact points. A plumb line is used to closely adhere to the wheel contact points on both sides. Then, one end of a level is parallel to and closely adhered to the plumb line, while the other end is raised until it contacts the vehicle body. The first point of contact between the level and the vehicle body is marked as the vehicle body perimeter. The position information of the vehicle body perimeter is obtained based on the marked point. The test point of the vehicle under test is determined based on the plumb line measurement information, the position information of the wheel contact points, and the position information of the vehicle body perimeter.

[0114] Furthermore, in order to accurately determine the test points of the vehicle under test, step S333 above may include:

[0115] Step S3331: Determine the near-ground mapping point of the vehicle body near point to the ground based on the vehicle body near point location information and the plumb bob measurement information;

[0116] Step S3332: Obtain the location information of the near-ground mapping point;

[0117] Step S3333: Determine the test point of the vehicle under test based on the location information of the near-ground mapping point and the location information of the wheel contact point.

[0118] It should be noted that the near-ground mapping point can be the location point where the vehicle's near point is vertically mapped to the ground. The angle measuring device can extend from the vehicle's near point to the ground using a plumb bob until it contacts the ground; this contact point is marked as the near-ground mapping point of the vehicle under test. The location information of the aforementioned near-ground mapping point can include its coordinates, location markings, or location distribution information, for example, the location information of the near-ground mapping point can be its coordinates relative to the wheel contact point.

[0119] This embodiment determines the vehicle's perimeter based on the position information of the wheel contact point and the level measurement information, obtains the position information of the vehicle's perimeter, and determines the test point of the vehicle based on the plumb bob measurement information, the position information of the wheel contact point, and the position information of the vehicle's perimeter. Because this invention measures the vehicle under test with a level, and thus determines the vehicle's perimeter based on the position information of the wheel contact point and the level measurement information, it achieves accurate positioning of the vehicle's perimeter. Compared with the prior art, this embodiment accurately positions the vehicle's perimeter, marks the perimeter, and obtains the position information of the perimeter based on the marked point. The test point of the vehicle is then determined based on the plumb bob measurement information, the position information of the wheel contact point, and the position information of the vehicle's perimeter, thereby ensuring the accuracy of the test point corresponding to the vehicle under test and effectively avoiding the problem of angle measurement errors caused by inaccurate selection of the test point.

[0120] Furthermore, this embodiment of the invention also proposes a storage medium storing a vehicle angle information measurement program, which, when executed by a processor, implements the steps of the vehicle angle information measurement method described above.

[0121] Since this storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0124] The state adjustment module 10 is used to control the vehicle under test to adjust to the angle test state when it receives the angle measurement command;

[0125] Information acquisition module 20 is used to acquire the plumb bob measurement information and level measurement information of the vehicle under test in the included angle test state;

[0126] The measurement point acquisition module 30 is used to determine the measurement points of the vehicle under test based on the plumb bob measurement information and the level measurement information.

[0127] Angle acquisition module 40 is used to acquire the position information of the point to be measured, and determine the angle information between the vehicle to be measured and the ground based on the position information of the point to be measured.

[0128] Furthermore, the measuring point acquisition module 30 is also used to determine the wheel contact point of the vehicle under test based on the plumb bob measurement information; acquire the position information of the wheel contact point; and determine the test point of the vehicle under test based on the plumb bob measurement information, the level measurement information, and the position information of the wheel contact point.

[0129] Furthermore, the measuring point acquisition module 30 is also used to determine the vehicle body perimeter of the vehicle under test based on the position information of the wheel contact point and the level measurement information; acquire the position information of the vehicle body perimeter; and determine the test point of the vehicle under test based on the plumb bob measurement information, the position information of the wheel contact point and the position information of the vehicle body perimeter.

[0130] Furthermore, the measurement point acquisition module 30 is also used to determine the near-ground mapping point of the vehicle body near point mapped to the ground based on the position information of the vehicle body near point and the measurement information of the plumb bob; acquire the position information of the near-ground mapping point; and determine the test point of the vehicle under test based on the position information of the near-ground mapping point and the position information of the wheel contact point.

[0132] Furthermore, the included angle acquisition module 40 is also used to determine the distance between the vehicle's perihelion and the near-ground mapping point based on the location information of the point to be measured; and to determine the included angle information between the vehicle to be measured and the ground based on the distance and the line length.

[0133] Furthermore, the angle acquisition module 40 is also used to obtain the angle information between the vehicle under test and the ground based on the spacing and the line length using a preset angle formula, wherein the preset angle formula is as follows:

[0134] φ = DEGREES(ATAN(H / L))

[0135] In the formula, φ is the angle between the vehicle under test and the ground, H is the distance, and L is the line length.

[0136] This embodiment controls the vehicle under test to adjust to the angle testing state upon receiving an angle measurement command. It acquires the plumb bob and level measurements of the vehicle under test in this state, determines the test point based on the plumb bob and level measurements, obtains the position information of the test point, and determines the angle between the vehicle and the ground based on the position information of the test point. Because this invention controls the vehicle under test to adjust to the angle testing state upon receiving the angle measurement command, it ensures that the vehicle is in a state that meets the angle testing conditions, effectively avoiding errors in angle testing. It acquires the plumb bob and level measurements of the vehicle under test in this state, determines the test point based on the plumb bob and level measurements, and thus accurately locates the test point. Based on the position information of the test point, it determines the angle between the vehicle and the ground, achieving accurate measurement of vehicle angle information, effectively avoiding measurement errors, and improving the efficiency of angle information measurement.
