Description

Technical Field

[0001] The present application relates to the field of vehicle testing technology, and in particular to a position information offset method and system, electronic equipment, and storage medium. Background Art

[0002] In the vehicle-to-everything (V2X-HIL) testing of the vehicle network, multiple different simulation scenarios need to be tested, so the switching of 3D scenes is a key technology for achieving smooth transition of the vehicle in different simulation scenarios.

[0003] During the test, the simulated vehicle needs to be positioned, and currently it is completely dependent on the simulated global navigation satellite system. The simulated global navigation satellite system locates the position information of the simulated vehicle in real time, and sends the located position information directly to the device under test, thereby updating the position of the simulated vehicle in real time.

[0004] However, when switching to a new scene, if the starting position of the simulated vehicle in the new scene is usually quite different from the ending position in the previous scene, the position of the simulated vehicle will suddenly change when the positioning information is directly used to position the vehicle, that is, the actual position in the new scene is directly transmitted to the DUT for positioning. This sudden position change not only affects the realism of the simulation, but also causes the DUT to fail to respond correctly, resulting in distorted simulation results. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0064] The present application embodiment provides a method for offsetting location information, such as Figure 1 As shown, the following steps are included:

[0065] S101, obtaining the position information of the end position of the previous scene and the position information of the start position of the current scene.

[0066] The location information includes the longitude and latitude of the location.

[0067] Specifically, the longitude and latitude of the position at the end of the test of the previous scene are obtained, and after the scene is switched, the longitude and latitude of the starting position of the current scene after the scene is switched are obtained. For example, the latitude of the end position of the previous scene is 30.0 degrees and the longitude is 120.0 degrees.

[0068] S102: Calculate the distance between the end position and the start position based on the position information of the end position and the position information of the start position.

[0069] It should be noted that in order to allow the car to smoothly transition from the end position to the start position, it is necessary to calculate the position information of multiple gently changing positions between the end position and the start position. Therefore, it is necessary to consider the movement of the car in this process, so it is necessary to calculate the distance between the end position and the start position so that its movement in this distance can be considered in subsequent steps.

[0070] Optionally, in another embodiment of the present application, a specific implementation of step S102 is as follows: Figure 2 As shown, including:

[0071] S201. Calculate the longitude difference and latitude difference between the end position and the start position based on the position information of the end position and the position information of the start position.

[0072] Specifically, the difference between the longitude of the end position and the longitude of the start position is calculated to obtain the longitude difference between the end position and the start position. Similarly, the difference between the latitude of the end position and the latitude of the start position is calculated to obtain the latitude difference between the end position and the start position.

[0073] S202: Calculate the distance between the end position and the start position using the longitude difference and latitude difference between the end position and the start position and the radius of the earth.

[0074] Specifically, the distance between the end position and the start position is calculated by the Haversine formula using the longitude difference and latitude difference between the end position and the start position and the radius of the earth.

[0075] Optionally, considering that the end position may be relatively close to the start position, there will be no sudden change in position, and there is no need to perform position shift. Therefore, in another embodiment of the present application, after executing step S102 and before executing step S103, the following may be further performed:

[0076] Based on the distance between the end position and the start position, determine whether position information offset is required.

[0077] Specifically, it may be determined whether the distance between the end position and the start position is less than a preset distance. If it is determined that the distance between the end position and the start position is less than the preset distance, it is determined that the position information shift is not required. If it is determined that the distance between the end position and the start position is not less than the preset distance, it is determined that the position information shift is required.

[0078] If it is determined that position shifting is required, step S103 is executed.

[0079] S103, calculating the driving time and driving distance of each driving stage within the distance between the end position and the start position according to the preset maximum speed and the preset acceleration.

[0080] The driving phase includes an acceleration phase, a constant speed phase and a deceleration phase.

[0081] It should be noted that in order to allow the car to have a smooth and stable transition from the end position to the actual position and avoid abnormal positioning of the measured part, in the embodiment of the present application, the process of the car from the end position to the starting position is realized in three stages of movement, namely, the acceleration stage, the uniform speed stage and the deceleration stage. The movement mode of each stage is different, so the calculation of its position is also different. Therefore, it is necessary to calculate the driving time and driving distance of each driving stage within the distance between the end position and the starting position, so as to be able to calculate the position information of the position in each stage in a targeted manner.

[0082] It should also be noted that during the acceleration phase, the vehicle is accelerated at a certain acceleration until it reaches a certain speed. During the uniform speed phase, the vehicle is driven at a preset maximum speed. During the deceleration phase, the vehicle is decelerated from a certain speed at a certain acceleration.

[0083] Therefore, according to the scene change, the preset maximum speed and preset acceleration are set to ensure smooth and stable transition, so that in the acceleration stage, the speed is accelerated from zero to the preset maximum speed according to the preset acceleration; in the uniform speed stage, the vehicle is driven according to the preset maximum speed; in the deceleration stage, the vehicle is decelerated from the preset maximum speed to zero according to the preset acceleration. Therefore, the driving time and driving distance of the three driving stages within the distance between the end position and the starting position can be calculated according to the preset maximum speed and the preset acceleration.

[0084] Optionally, in another embodiment of the present application, a specific implementation of step S103 is as follows: Figure 3 As shown, the following steps are included:

[0085] S301, calculating the driving time and driving distance for accelerating the speed from zero to a preset maximum speed according to a preset acceleration, and obtaining the driving time and driving distance in the acceleration phase.

[0086] S302: Calculate the driving time and driving distance required to decelerate the speed from a preset maximum speed to zero according to a preset acceleration, and obtain the driving time and driving distance in the deceleration stage.

[0087] S303: Subtract the sum of the driving distance in the acceleration phase and the driving distance in the deceleration phase from the distance between the end position and the start position to obtain the driving distance in the uniform speed phase.

[0088] S304: Calculate the driving time in the uniform speed stage based on the preset maximum speed and the driving distance in the uniform speed stage.

[0089] For example, the preset maximum speed of the vehicle is 10.0m / s and the preset acceleration is 2m / s 2 , the time and distance of the three driving stages can be calculated respectively:

[0090] Driving time and distance during the acceleration phase: t_acc = 5.0000 seconds, d_acc = 25.0000 meters.

[0091] Driving time and distance during the uniform speed phase: t_cruise = 2.3631 seconds, d_cruise = 23.6308 meters.

[0092] Travel time and travel distance during the deceleration phase: t_dec = 5.0000 seconds, d_dec = 25.0000 meters.

[0093] S104, dividing the time from the end position to the start position into a plurality of time periods.

[0094] In order to smoothly transition from the end position to the start position, in the embodiment of the present application, multiple position points between the end position and the start position are analyzed. Therefore, the total driving time from the end position to the start position is divided into multiple time periods, so that the position information of the position after each time period can be analyzed respectively.

[0095] Optionally, the time from the end position to the start position may be divided into a plurality of time periods according to preset time intervals.

[0096] S105: Based on the driving time and driving distance of each driving stage, calculate and obtain the position information corresponding to each time period.

[0097] The location information corresponding to each time period refers to the location information of the location after the driving time period.

[0098] Specifically, based on the driving time and driving distance of each driving stage, the driving stage of each time period can be determined, so as to determine whether the vehicle is accelerating, driving at a constant speed or accelerating in the time period, that is, by determining the driving stage, the driving mode can be determined, and then the driving distance in the time period can be further analyzed according to the driving mode, and finally the longitude and latitude can be determined according to the driving distance. Specifically, the offset of longitude and latitude can be determined by the driving distance, that is, the change in distance, so as to determine the longitude and latitude of the position of the vehicle after driving in the time period, and obtain the position information corresponding to the time period.

[0099] Optionally, in another embodiment of the present application, a specific implementation of step S105 is as follows: Figure 4 As shown, including:

[0100] S401. Based on the driving time and driving distance of each driving stage, the driving distance of each time period is calculated by linear interpolation.

[0101] It should be noted that the driving time and driving distance of each driving stage are equivalent to the time and distance of multiple position points, and the position points of each driving time period are between the position points corresponding to each driving stage, and the time of each time period is known, so the driving distance of each time period can be directly calculated by linear interpolation based on the time and distance of the last two position points, that is, the distance traveled by the car in each time period.

[0102] S402: Calculate the position information corresponding to each time period based on the heading angle from the end position to the start position and the travel distance in each time period.

[0103] Specifically, the driving distance in a certain time period can be decomposed into vectors in the longitude and latitude directions according to the heading angle from the end position to the start position, so that the change in longitude and latitude can be determined based on these two vectors, and further based on the longitude and latitude of the previous position, the location information corresponding to the time period can be determined.

[0104] S106: Using the position information corresponding to each time period, a smooth transition path from the end position to the start position is formed.

[0105] Specifically, the position information corresponding to each time period can be transmitted to the simulation system, so that the simulation system can use the position information corresponding to each time period to form a smooth transition path from the end position to the start position to avoid sudden changes in position.

[0106] The embodiment of the present application provides a method for offsetting position information, which obtains the position information of the end position of the previous scene and the position information of the start position of the current scene. Wherein, the position information includes the longitude and latitude of the position. Then, based on the position information of the end position and the position information of the start position, the distance between the end position and the start position is calculated so that analysis can be performed on this distance. According to the preset maximum speed and the preset acceleration, the driving time and driving distance of each driving stage within the distance between the end position and the start position are calculated. Wherein, the driving stage includes an acceleration stage, a uniform speed stage, and a deceleration stage, so that the three stages of driving can be passed to ensure that the position information can be stably and smoothly transitioned from the end position to the start position. Then, the time from the end position to the start position is divided into multiple time periods, and based on the driving time and driving distance of each driving stage, the position information corresponding to each time period is calculated. Wherein, the position information corresponding to each time period refers to the position information of the position after the driving time period. Finally, the position information corresponding to each time period is used to form a smooth transition path from the end position to the starting position, thereby realizing a method for analyzing the position information of multiple positions between the end position and the starting position. By analyzing each position point, it is possible to smoothly transition from the end position to the starting position, avoiding sudden position changes and thus avoiding distortion of the simulation results.
