[0068] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0069] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0070] Figure 1 This is a flowchart illustrating a vehicle roadmap simulation control method according to an embodiment of the present invention. This embodiment is applicable to the simulation of vehicle roadmaps. The method can be executed by a vehicle roadmap simulation control device, which can be implemented in hardware and / or software. Figure 1 As shown, the method includes:

[0071] S101, Obtain the preset vehicle road map.

[0072] The preset vehicle road profile is the curve of the change between the first time and the first speed, which can be obtained according to the actual design requirements of the vehicle.

[0073] S102, run the preset vehicle road map and obtain the first real-time mileage.

[0074] The system simulates the operation of the entire vehicle according to a preset vehicle road map, and simultaneously acquires the first real-time mileage of the vehicle's operation.

[0075] S103, Get preset mileage.

[0076] The preset mileage can be set according to actual design requirements, and this embodiment of the invention does not impose specific limitations.

[0077] S104, obtain the first adjusted vehicle road spectrum based on the first real-time mileage and the preset mileage.

[0078] During the simulated operation of the vehicle, there will be a mileage deviation between the real-time mileage and the preset mileage. In order to ensure the feasibility of the road spectrum comparison experiment, the road spectrum can be adjusted. Usually, when the mileage deviation is large, the running time needs to be increased appropriately, and then the first adjusted vehicle road spectrum is obtained based on the current first real-time mileage and the preset mileage.

[0079] S105, runs the first adjustment vehicle road spectrum and obtains real-time gradient.

[0080] The vehicle is simulated to run according to the adjusted first vehicle road spectrum, and the real-time gradient is also acquired during the operation.

[0081] S106, obtain the preset slope.

[0082] The preset slope can be set according to actual design requirements, and the embodiments of the present invention do not impose specific limitations.

[0083] S107, obtains the second adjusted vehicle road spectrum based on real-time slope and preset slope.

[0084] Since the first adjusted vehicle route spectrum usually increases the running time, in order to ensure the consistency of the total time, the vehicle speed can be appropriately increased and the running time shortened. At the same time, it is necessary to ensure acceleration under road conditions with a small gradient. Therefore, the second adjusted vehicle route spectrum needs to be obtained based on the real-time gradient and the preset gradient.

[0085] S108, run the second adjustment vehicle road spectrum and obtain the second real-time mileage.

[0086] During the simulated operation of the vehicle according to the first adjusted vehicle road spectrum, it is necessary to obtain the second real-time mileage again.

[0087] S109 obtains vehicle speed adjustment information based on the second real-time mileage and the preset mileage.

[0088] Specifically, when the mileage deviation is small enough and the total time and total mileage are consistent with the set vehicle, it is necessary to obtain vehicle speed adjustment information and adjust the vehicle speed to ensure the overall vehicle operation status.

[0089] S110 adjusts vehicle speed information to complete the whole vehicle road spectrum simulation.

[0090] The vehicle needs to adjust its speed information to continue the simulation until the simulation ends.

[0091] This invention, in its embodiments, acquires a preset vehicle road spectrum based on a first time and a first vehicle speed; runs the preset vehicle road spectrum and acquires a first real-time mileage; acquires a preset mileage; acquires a first adjusted vehicle road spectrum based on the first real-time mileage and the preset mileage; runs the first adjusted vehicle road spectrum and acquires a real-time gradient; acquires a preset gradient; acquires a second adjusted vehicle road spectrum based on the real-time gradient and the preset gradient; runs the second adjusted vehicle road spectrum and acquires a second real-time mileage; acquires vehicle speed adjustment information based on the second real-time mileage and the preset mileage; and completes the whole vehicle road spectrum simulation based on the vehicle speed adjustment information. This improves the fitting degree of the road spectrum and enhances the accuracy of reflecting the overall vehicle operating status.

[0092] Optional, Figure 2 A flowchart of another vehicle road spectrum simulation control method provided in an embodiment of the present invention is shown below. Figure 2 As shown, the method includes:

[0093] S201, Obtain the preset vehicle road map.

[0094] S202, run the preset vehicle road map and obtain the first real-time mileage.

[0095] S203, obtain preset mileage.

[0096] S204, obtain the first mileage deviation value based on the first real-time mileage and the preset mileage.

[0097] Specifically, the difference between the first real-time mileage and the preset mileage is calculated to obtain the first mileage deviation value.

[0098] S205, obtain the first preset mileage deviation value.

[0099] The first preset mileage deviation value can be set according to actual design requirements, and the embodiments of the present invention do not impose specific limitations.

[0100] S206, determine whether the first mileage deviation value is greater than the first preset mileage deviation value; if yes, proceed to step S207; if no, proceed to step S202.

[0101] S207, Obtain the first adjusted vehicle road spectrum.

[0102] Specifically, when the first mileage deviation value is less than or equal to the first preset mileage deviation value, it is considered that the current simulated vehicle operation state is consistent with the operation state of the set vehicle under the same preset vehicle road spectrum, and the simulation operation continues according to the preset vehicle road spectrum. When the first mileage deviation value is greater than the first preset mileage deviation value, it is considered that there is a large deviation between the current simulated vehicle operation state and the operation state of the set vehicle under the same preset vehicle road spectrum, and it is necessary to appropriately increase the operation time to obtain the first adjusted vehicle road spectrum.

[0103] S208, runs the first adjustment vehicle road spectrum and obtains real-time gradient.

[0104] S209, obtain the preset slope.

[0105] S210 obtains a second adjusted vehicle road spectrum based on real-time gradient and preset gradient.

[0106] S211, run the second adjustment vehicle road spectrum and obtain the second real-time mileage.

[0107] S212, obtains vehicle speed adjustment information based on the second real-time mileage and the preset mileage.

[0108] S213, adjusts vehicle speed information to complete the whole vehicle road spectrum simulation.

[0109] This invention, in its embodiments, acquires a preset vehicle road spectrum based on a first time and a first vehicle speed; runs the preset vehicle road spectrum and acquires a first real-time mileage; acquires a preset mileage; acquires a first mileage deviation value based on the first real-time mileage and the preset mileage; acquires a first preset mileage deviation value; acquires a first adjusted vehicle road spectrum based on the first mileage deviation value and the first preset mileage deviation value; runs the first adjusted vehicle road spectrum and acquires a real-time gradient; acquires a preset gradient; acquires a second adjusted vehicle road spectrum based on the real-time gradient and the preset gradient; runs the second adjusted vehicle road spectrum and acquires a second real-time mileage; acquires vehicle speed adjustment information based on the second real-time mileage and the preset mileage; and completes the whole vehicle road spectrum simulation based on the vehicle speed adjustment information. This improves the fitting degree of the road spectrum and enhances the accuracy of reflecting the overall vehicle operating status.

[0110] Optional, Figure 3 A flowchart of another vehicle road spectrum simulation control method provided in an embodiment of the present invention is shown below. Figure 3 As shown, the method includes:

[0113] S303, get the preset mileage.

[0114] S304, obtain the first mileage deviation value based on the first real-time mileage and the preset mileage.

[0115] S305, obtain the first preset mileage deviation value.

[0116] S306, determine whether the first mileage deviation value is greater than the first preset mileage deviation value; if yes, proceed to step S307; if no, proceed to step S302.

[0117] S307, Get the current vehicle speed.

[0118] S308 calculates the increase in running time based on the current vehicle speed and the first mileage deviation value.

[0119] S309, obtain the first adjusted vehicle road spectrum based on the increase in running time.

[0120] The process involves obtaining the current vehicle speed, performing a division operation between the first mileage deviation value and the current vehicle speed to obtain the increase in running time, adjusting the vehicle's route spectrum according to the increase in running time, and then continuing to simulate the vehicle's operation under the first adjusted vehicle route spectrum to reduce the mileage deviation.

[0121] S310, runs the first adjustment vehicle road spectrum and obtains real-time gradient.

[0122] S311, obtain the preset slope.

[0123] S312, obtains the second adjusted vehicle road spectrum based on real-time slope and preset slope.

[0125] S314 obtains vehicle speed adjustment information based on the second real-time mileage and the preset mileage.

[0126] S315 adjusts vehicle speed information to complete the whole vehicle road spectrum simulation.

This improves the fitting degree of the road spectrum and enhances the accuracy of reflecting the overall vehicle operating status.

[0128] Optional, Figure 4 A flowchart of another vehicle road spectrum simulation control method provided in an embodiment of the present invention is shown below. Figure 4 As shown, the method includes:

[0129] S401, Obtain the preset vehicle road map.

[0130] S402, run the preset vehicle road map and obtain the first real-time mileage.

[0131] S403, get preset mileage.

[0143] S415, obtain the second adjusted vehicle road spectrum.

[0144] In the simulation of the vehicle running according to the first adjusted vehicle road spectrum, to compensate for mileage deviations, the running time is increased using the increase in running time. Therefore, the road spectrum needs to be adjusted again to avoid increasing the total time. This requires obtaining the actual slope and the preset slope. The slope deviation value is obtained by calculating the difference between the actual slope and the preset slope. Simultaneously, the preset slope deviation value is also obtained. The preset slope deviation value can be set according to actual design requirements, and this embodiment of the invention does not impose specific limitations. An exemplary preset slope deviation value can be 2.5%. When the slope deviation value is less than the preset slope deviation value, the current road slope is considered relatively small, suitable for vehicle acceleration, and road spectrum adjustment can be performed to obtain the second adjusted vehicle road spectrum. When the slope deviation value is greater than or equal to the preset slope deviation value, the current road slope is considered relatively large, unsuitable for vehicle acceleration.

[0145] S416, run the second adjustment vehicle road spectrum and obtain the second real-time mileage.

[0146] S417 obtains vehicle speed adjustment information based on the second real-time mileage and the preset mileage.

[0147] S418 adjusts vehicle speed information to complete the whole vehicle road spectrum simulation.

[0164] S515, obtain the vehicle speed increase value.

[0165] S516, the second adjusted vehicle road spectrum is obtained based on the increase in vehicle speed and the increase in running time.

[0166] When the slope deviation value is smaller than the preset slope deviation value, the vehicle speed increase value can be obtained, the vehicle speed can be increased, and the running time increase value under the first adjusted vehicle road spectrum can be removed to obtain the second adjusted vehicle road spectrum. This is equivalent to shortening the running time by increasing the vehicle speed in actual conditions, thereby ensuring that the simulated running state of the whole vehicle is consistent with the running state of the set vehicle.

This improves the fitting degree of the road spectrum and enhances the accuracy of reflecting the overall vehicle operating status.

[0171] Optional, Figure 6 A flowchart of another vehicle road spectrum simulation control method provided in an embodiment of the present invention is shown below. Figure 6 As shown, the method includes:

[0177] S606, determine whether the first mileage deviation value is greater than the first preset mileage deviation value; if yes, proceed to step S607; if no, proceed to step S602.

[0178] S607, Get the current vehicle speed.

[0179] S608 calculates the increase in running time based on the current vehicle speed and the first mileage deviation value.

[0180] S609, obtain the first adjusted vehicle road spectrum based on the increase in running time.

[0181] S610, runs the first adjustment vehicle road spectrum and obtains real-time gradient.

[0182] S611, obtain the preset slope.

[0183] S612 obtains the slope deviation value based on the real-time slope and the preset slope.

[0184] S613, obtain the preset slope deviation value.

[0185] S614, determine whether the slope deviation value is less than the preset slope deviation value; if yes, proceed to step S615; if no, proceed to step S610.

[0186] S615, obtain the vehicle speed increase value.

[0187] S616, obtains the second adjusted vehicle road spectrum based on the increase in vehicle speed and the increase in running time.

[0189] S618, obtains the second mileage deviation value based on the second real-time mileage and the preset mileage.

[0190] S619, obtain the second preset mileage deviation value.

[0191] S620, determine whether the second mileage deviation value is less than the second preset mileage deviation value; if yes, proceed to step S621; if no, proceed to step S617.

[0192] S621, obtain vehicle speed adjustment information.

[0193] In this process, during the simulated operation of the vehicle according to the second adjusted vehicle road spectrum, a second real-time mileage is acquired. Simultaneously, a difference calculation is performed using this second mileage to obtain a second mileage deviation value. A second preset mileage deviation value is also acquired. This second preset mileage deviation value can be set according to actual design requirements, and this embodiment of the invention does not impose specific limitations. When the second mileage deviation value is less than the second preset mileage deviation value, it is considered that, with the total simulated operation time remaining unchanged, the mileage deviation is sufficiently small, and the total mileage is approximately the same. Therefore, vehicle speed adjustment information is acquired, and vehicle speed is adjusted to ensure the vehicle continues to simulate operation. When the second mileage deviation value is greater than or equal to the second preset mileage deviation value, it is considered that the simulated operation state of the vehicle still differs from the set vehicle, and therefore, operation continues according to the second adjusted vehicle road spectrum.

[0194] S622 adjusts vehicle speed information to complete the whole vehicle road spectrum simulation.

[0195] This invention embodiment acquires a preset vehicle road spectrum based on a first time and a first vehicle speed; runs the preset vehicle road spectrum and acquires a first real-time mileage; acquires a preset mileage; acquires a first mileage deviation value based on the first real-time mileage and the preset mileage, and acquires a first preset mileage deviation value; acquires the current vehicle speed; acquires an increase in running time based on the current vehicle speed and the first mileage deviation value; acquires a first adjusted vehicle road spectrum based on the increase in running time; runs the first adjusted vehicle road spectrum and acquires a real-time gradient; acquires a preset gradient; acquires a preset gradient deviation value when the gradient deviation value is less than the preset gradient deviation value; acquires a speed increase value based on the gradient deviation value and the preset gradient deviation value, and acquires a second adjusted vehicle road spectrum based on the speed increase value and the increase in running time; runs the second adjusted vehicle road spectrum and acquires a second real-time mileage; acquires a second mileage deviation value based on the second real-time mileage and the preset mileage; acquires a second preset mileage deviation value; acquires vehicle speed adjustment information based on the second mileage deviation value and the second preset mileage deviation value; and completes the whole vehicle road spectrum simulation based on the vehicle speed adjustment information. This improves the fitting degree of the road spectrum and enhances the accuracy of reflecting the whole vehicle's operating status.

[0196] Optional, Figure 7 A flowchart of another vehicle road spectrum simulation control method provided in an embodiment of the present invention is shown below. Figure 7 As shown, the method includes:

[0197] S701, Obtain the preset vehicle road map.

[0198] S702 runs the preset vehicle road map and obtains the first real-time mileage.

[0199] S703, get preset mileage.

[0200] S704, obtain the first mileage deviation value based on the first real-time mileage and the preset mileage.

[0201] S705, obtain the first preset mileage deviation value.

[0202] S706, determine whether the first mileage deviation value is greater than the first preset mileage deviation value; if yes, proceed to step S707; if no, proceed to step S702.

[0203] S707, Get the current vehicle speed.

[0204] S708 calculates the increase in running time based on the current vehicle speed and the first mileage deviation value.

[0205] S709, obtain the first adjusted vehicle road spectrum based on the increase in running time.

[0217] S721, restore vehicle speed under the preset vehicle road spectrum.

[0218] When the second mileage deviation value is less than the second preset mileage deviation value, it is considered that the total mileage deviation during the whole vehicle simulation operation is small enough. Therefore, the vehicle speed during the whole vehicle simulation operation can be restored to the vehicle speed under the preset vehicle road spectrum, that is, the simulation operation can continue according to the preset vehicle road spectrum.

[0219] S722, based on the vehicle speed under the preset vehicle road spectrum, completes the whole vehicle road spectrum simulation.

[0220] In this embodiment of the invention, when the second mileage deviation value is less than the second preset mileage deviation value, the vehicle speed is restored to the speed under the preset vehicle road spectrum, and operation continues to complete the vehicle road spectrum simulation. This improves the fitting degree of the road spectrum and enhances the accuracy of reflecting the vehicle's operating status.
