Abstract
Description
Technical Field
[0001] This specification relates to the field of vehicle technology, and in particular to a method and device for vehicle speed control. Background Technology
[0002] In existing technologies, when a vehicle uses an advanced driver assistance system (ADAS) for cruise control, the vehicle's speed can be adjusted based on the surrounding traffic conditions to control the distance between the vehicle and other vehicles. When adjusting the vehicle's speed, the maximum permissible speed is determined by combining the speed limit of the current road segment with a set speed. For example, the maximum permissible speed is set when there are no other vehicles around. However, in existing speed control methods, the method of determining the maximum permissible speed on a road segment is limited in its effectiveness when dealing with complex and changing road conditions. Because it only considers the speed limit of the current road segment, it provides limited assistance to the driver and fails to provide a good driving experience. Summary of the Invention

[0026] To enable vehicles to cruise at speeds that better match actual road conditions and provide a better driving experience for users, this invention provides a vehicle speed control method. The method will be described in detail below through exemplary embodiments, but should not be construed as limiting.
[0027] Figure 1 This is a flowchart illustrating an exemplary embodiment of a vehicle speed control method applied to a vehicle. Figure 1 As shown, the method may include the following processes:
[0028] In step S101, the vehicle speed control method used by the vehicle is obtained.
[0029] When a user wants to use the driver assistance system to control the vehicle's cruise control, the system can adjust the vehicle's speed based on the surrounding traffic conditions, such as the distance between the surrounding vehicles and the vehicle itself. However, when the surrounding vehicles are far away, the driver assistance system can increase the vehicle's speed. The maximum speed increase depends on the control method selected by the user.
[0030] The vehicle's central control interface allows users to select speed control methods. For example, the interface may display options such as big data speed control and speed limit control. The vehicle will adjust its speed according to the user's selection. When the user selects big data speed control, the vehicle will determine the maximum speed that can be adjusted for that road segment based on the big data speed limits. When the user selects speed limit control, the vehicle will determine the maximum speed that can be adjusted for that road segment based on the speed limit.
[0031] In step S102, in response to the vehicle speed control method being a big data vehicle speed control method, the big data vehicle speed and speed limit of the current road segment of the vehicle are obtained.
[0032] During vehicle operation, the vehicle control system can acquire big data vehicle speeds and speed limits corresponding to various road segments. For example, high-precision maps can be used to obtain these data. The big data vehicle speeds can be the most frequently used speeds for vehicles on the current road segment, while the speed limits are the speed limits shown on the speed limit signs for that segment. Besides obtaining speed limits through high-precision maps, sensors on the vehicle can also be used to obtain the speed limits shown on external speed limit signs. There are no restrictions on the methods used to acquire the big data vehicle speeds and speed limits.
[0033] Each road segment corresponds to a big data speed limit. For example, on a 10-kilometer-long highway, the speed limit is always 40 kilometers per hour. However, the big data speed limit for the first five kilometers is 30 kilometers per hour, and the big data speed limit for the last five kilometers is 35 kilometers per hour. Therefore, this highway can be divided into two segments: the first segment has a big data speed limit of 30 kilometers per hour and a speed limit of 40 kilometers per hour; the second segment has a big data speed limit of 35 kilometers per hour and a speed limit of 40 kilometers per hour.
[0034] In step S103, in response to the big data vehicle speed being in a preset first speed range, the vehicle speed control threshold is set to the big data vehicle speed, and the first speed range is set according to the speed limit vehicle speed.
[0035] When a vehicle activates its big data-based speed control mode, it determines a first speed range based on the acquired speed limit. This first speed range can be defined as greater than a fixed value but less than a fixed multiple of the speed limit. For example, if the acquired speed limit is 100 km / h, the first speed range can be defined as 30 km / h to 110 km / h. When the big data speed falls within this range, the vehicle uses that big data speed as the speed control threshold for the current road segment.
[0036] In step S104, the vehicle speed is adjusted according to the vehicle speed adjustment threshold so that the adjusted vehicle speed is less than or equal to the vehicle speed adjustment threshold.
[0037] When a vehicle uses a driver assistance system to adjust its speed, the adjusted speed can only be less than or equal to the speed adjustment threshold. For example, when there are vehicles around the vehicle, the driver assistance system will reduce the speed based on the speed of the surrounding vehicles. However, when there are no vehicles around, the driver assistance system will increase the speed, but it cannot make the speed exceed the speed adjustment threshold. Adjusting the speed based on the surrounding vehicles is an existing technology in the industry, and will not be elaborated on here.
[0038] In one example, when a vehicle first activates the big data speed control method during its journey, it can directly use the big data speed of that road segment as the speed control threshold without needing to define a specific range. Alternatively, if the big data speed obtained after defining a range is not within that range when the big data speed control method is first activated, the speed limit of the current road segment can be directly used as the speed control threshold.
[0039] In one example, when a vehicle reaches the next road segment, it acquires the new segment's big data speed and speed limit. Based on the new speed limit, a new first speed range is determined according to preset rules. It is then determined whether the big data speed for this new road segment falls within the first speed range of the new segment. If so, the vehicle uses the big data speed corresponding to this new road segment as the speed control threshold for that new segment; otherwise, the speed control threshold remains unchanged.
[0040] In one example, after setting the vehicle speed control threshold to the big data vehicle speed, the method further includes: in response to receiving a setting instruction for a set vehicle speed, obtaining the set vehicle speed after setting based on the setting instruction; and updating the vehicle speed control threshold to the set vehicle speed.
[0041] After activating the big data speed control mode, the vehicle uses the big data speed as the speed control threshold for the current road segment and adjusts the speed accordingly. If the user is not satisfied with the speed control threshold determined by the big data speed, they can set a new speed setting by long-pressing or tapping the control button. The vehicle will then use this new speed setting as the speed control threshold for the driver assistance system when adjusting the speed on the current road segment.
[0042] For example, if the user's current speed is determined by big data and the speed control threshold is 50 kilometers per hour, and there are no other vehicles around the vehicle, the driver assistance system can adjust the vehicle speed to the speed control threshold, i.e., 50 kilometers per hour. However, if the user is not satisfied with this speed threshold, the user can adjust the button to set a set speed, such as 70 kilometers per hour. At this time, the speed threshold for the vehicle on the current road segment is 70 kilometers per hour, and the driver assistance system can adjust the speed to 70 kilometers per hour based on the surrounding vehicle conditions.
[0043] When a user issues a setting command for a vehicle speed, it can be either the first time setting the speed or when the vehicle already has a set speed, and the user adjusts the set speed using the setting command. When a user sets a speed for the first time, it can be understood that the vehicle previously had no set speed; after receiving the setting command for the first time, the vehicle has the set speed. Once the vehicle has a set speed, it can be adjusted subsequently using setting commands, and the adjusted set speed will be used as the speed control threshold for the current road segment.
[0044] This can be understood as the vehicle's set speed changing according to the user's settings. When the vehicle has no set speed, the set speed does not need to be considered when determining the speed range. When the vehicle has a set speed, the first speed range for big data speeds can be determined based on the vehicle's current set speed and the speed limit of the current road segment.
[0045] In addition to adjusting the vehicle speed via buttons, users can also adjust the speed via the accelerator. After increasing the vehicle speed to a satisfactory level using the accelerator, pressing the button will set the vehicle's speed to the current satisfactory speed and use this set speed as the speed control threshold for the current road segment.
[0046] In one example, after updating the vehicle speed control threshold to the set vehicle speed, the method further includes: if the vehicle's travel segment changes from the current segment to a first segment, obtaining the speed limit speed and big data speed of the first segment, and determining the changed first speed range based on the set vehicle speed and the speed limit speed of the first segment; in response to the big data speed of the first segment being within the changed first speed range, adjusting the vehicle speed control threshold to the big data speed of the first segment.
[0047] This can be understood as follows: once a vehicle has a set speed, it will use that set speed as the speed control threshold in the current road segment. However, when entering the next road segment, i.e., entering the first road segment, the vehicle speed control threshold needs to be redefined. When determining the first speed range for the big data speed of the new road segment, in addition to considering the speed limit of the new road segment, it is also necessary to consider the magnitude of the vehicle's set speed at this time, and use this to set the first speed range for that road segment.
[0048] For example, when a vehicle has a set speed, the first speed range for a new road segment can be set to be greater than a fixed value, less than the vehicle's current set speed, and the difference between the set speed and the set speed should be less than a fixed value and less than a fixed multiple of the speed limit. This fixed multiple can be less than 1. These conditions are used to determine the first speed range for the new road segment. It's important to note that the rules for setting the first speed range can be configured according to vehicle strategy; there are no restrictions here. When the average speed of the vehicle on this new road segment falls within the first speed range of that new road segment, the vehicle's speed control threshold for the current road segment (i.e., the first road segment) is adjusted to this average speed. This process is repeated when the vehicle enters a new road segment during subsequent travel.
[0049] In one example, in response to the fact that the speed of the vehicle on the first road segment is not in the changed first speed range; if the speed limit of the first road segment is in the second speed range, the second speed range is determined according to the set speed; then the vehicle speed control threshold is adjusted to the speed limit of the first road segment.
[0050] When a vehicle enters a new road segment, if the speed recorded by the big data is not within the first speed range defined for that new road segment, it can be determined whether the speed limit for that road segment is within the second speed range. If the speed limit for that road segment is within the second speed range, the vehicle's speed control threshold can be adjusted to that speed limit. Since the vehicle currently has a set speed, determining the second speed range for the current road segment's speed limit requires basing it on the set speed.
[0051] For example, the second speed range for this road segment can be set to be greater than a fixed value but less than the vehicle's current set speed, and the difference between the speed limit and the set speed cannot be too large. The specific range settings are customizable and not restricted here. For instance, when entering a new road segment, if the vehicle's set speed is 100 km / h, and the user wants the speed limit to be greater than 30 km / h, less than the set speed, and the difference between the two speed limits cannot exceed 50 km / h, then the second speed range for this new road segment could be 50 km / h to 100 km / h.
[0052] In another scenario, if a user uses the big data speed control method but hasn't set a set speed (i.e., the vehicle has no set speed), when the vehicle enters a new road segment, the first speed range corresponding to the big data speed limit for that new road segment can be determined without considering the set speed. Furthermore, regardless of whether the big data speed control method is activated for the first time and the big data speed is not in the first speed range, or whether it has been activated for a while and the big data speed is not in the first speed range on a new road segment, the speed control threshold can be determined based on the speed limit. Whether it's the first speed range corresponding to the big data speed limit or the second speed range corresponding to the speed limit, the set speed can be disregarded when determining these ranges. For example, the first speed range corresponding to the big data speed limit can be set to be greater than a fixed value and less than a fixed multiple of the speed limit. This multiple doesn't have to be an integer and can be determined based on the actual situation. The second speed range corresponding to the speed limit can be set to be greater than a fixed value. The method of setting the speed range can be set according to the vehicle's own usage and is not restricted here.
[0053] In one example, the method further includes: in response to the fact that the speed of the first road segment is not in the changed first speed range and the speed limit of the first road segment is not in the second speed range, the vehicle speed control threshold remains unchanged.
[0054] This can be understood as follows: if the speed of vehicles in this section of the road is not within the corresponding speed range, then the vehicles will maintain their original speed control threshold, meaning that the vehicle speed control threshold will not change.
[0055] When the vehicle has no set speed, the above method is used to first determine whether the big data speed meets the first speed range corresponding to the situation. If it does not meet the speed range, the speed limit speed is then determined to meet the second speed range corresponding to the situation. When neither speed meets the conditions, the vehicle maintains the speed control threshold.
[0056] In one example, the vehicle speed control method includes: the big data vehicle speed control method and the speed limit vehicle speed control method; the method further includes: in response to the vehicle speed control method using the speed limit vehicle speed control method, obtaining the speed limit vehicle speed of the current road segment; in response to the vehicle having a set speed, determining a second speed range based on the set speed; in response to the speed limit vehicle speed being in the second speed range, adjusting the vehicle speed control threshold to the speed limit vehicle speed.
[0057] When users select a vehicle speed control method, in addition to the big data vehicle speed control method, they can also choose the speed limit vehicle speed control method. If the user selects the speed limit vehicle speed control method, only the speed limit of the current road segment can be obtained. If this speed limit vehicle speed is in the second speed range for the speed limit vehicle speed, then the speed limit vehicle speed will be used as the vehicle speed control threshold.
[0058] When a vehicle has a set speed, the second speed range needs to be determined based on that set speed. For example, the second speed range for a given road segment can be set to be greater than a fixed value but less than the vehicle's current set speed, and the difference between the speed limit and the set speed should not be too large. In another scenario, where the vehicle does not have a set speed, the second speed range for the given road segment can be set to be greater than a fixed value. The specific range setting method can be determined based on the vehicle's driving strategy.
[0059] When a vehicle enters a new road segment, its speed is controlled using a speed limit method. This involves acquiring only the speed limit for the new road segment and, depending on whether the vehicle has a set speed, determining a second speed range for that speed limit based on its corresponding rules. If the speed limit is within this range, the speed control threshold is adjusted to the speed limit; otherwise, the vehicle's speed control threshold remains unchanged.
[0060] The embodiments provided in this specification enable vehicles to acquire big data speeds and speed limits for road segments when using an assisted driving system to control vehicle speed. Based on the acquired speed limits and the vehicle's own conditions, a speed range is determined to assess whether the big data speeds meet the criteria. The compliant big data speeds are then used as the maximum speed for vehicle speed control. This allows for better speed control based on big data speeds during driving, enabling the vehicle to adapt more effectively to various road conditions and improving the driver's experience.
