[0001] The present invention relates to the field of automobiles, and in particular to a control method, computer equipment and storage medium for an AMT gearbox. Background Art

[0002] In actual working conditions, vehicles often experience neutral coasting downhill. However, based on driver experience and a large number of accident analyses, there are hidden dangers in maintaining neutral coasting when going downhill. On a steep downhill section, when the road slope is large, it is easy to cause the vehicle speed to be too fast and out of control. In order to avoid the situation where the vehicle speed is too fast and out of control when the slope is large, the neutral coasting strategy for downhill in the prior art can often only be performed when the accelerator pedal opening is zero. In addition, in the prior art, when the slope information ahead cannot be perceived, the neutral coasting speed needs to be limited to prevent the vehicle from losing control due to going down a steep slope.

[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0024] According to one aspect of an embodiment of the present application, a control method for an AMT gearbox is provided. Optionally, in this embodiment, the control method for an AMT gearbox can be applied to Figure 1 In the hardware environment composed of the terminal 102 and the server 104 shown in FIG. Figure 1 As shown, the server 104 is connected to the terminal 102 via a network, and can be used to provide services for the terminal or a client installed on the terminal. A database can be set on the server or independently of the server to provide data storage services for the server 104, and can also be used to process cloud services. The above network includes but is not limited to: a wide area network, a metropolitan area network or a local area network, and the terminal 102 is not limited to a PC, a mobile phone, a tablet computer, etc. The control method of the AMT gearbox of the embodiment of the present application can be executed by the server 104, or by the terminal 102, or by the server 104 and the terminal 102. Among them, the terminal 102 executes the control method of the AMT gearbox of the embodiment of the present application, and it can also be executed by the client installed thereon.

[0025] Taking the control method of the AMT transmission in this embodiment executed by the terminal 102 and / or the server 104 as an example, Figure 2 is a flow chart of an optional control method of an AMT transmission according to an embodiment of the present application, such as Figure 2 As shown, the process of the method may include the following steps:

[0026] Step S202, obtaining the slope information of the road section to be traveled;

[0027] Step S204, determining the ramp attribute information of the road section to be traveled according to the slope information, wherein the ramp attribute information includes a slope value and ramp position information;

[0028] Step S206: Determine the neutral coasting strategy for the road section to be driven according to the ramp attributes.

[0029] Through the above steps S202 to S206, after obtaining the slope information of the road section to be traveled, the ramp attribute information of the road section to be traveled is determined according to the slope information, and the ramp attribute information includes the slope value and the ramp position information. The ramp attribute information of the road section to be traveled is determined according to the slope information, and the ramp attribute information includes the slope value and the ramp position information. Through the above control method, the neutral gliding strategy when going downhill in the prior art is solved, and neutral gliding can often only be performed when the accelerator pedal opening is zero. When the slope information ahead cannot be perceived, the speed of neutral gliding needs to be limited to prevent the problem of vehicle loss of control due to going down a steep slope, so as to achieve the effect of being able to maximize the use of the vehicle's kinetic energy to complete downhill driving and reduce fuel consumption.

[0030] For the technical solution in step S202, the slope information of the road section to be traveled is obtained. Exemplarily, as an optional embodiment, the slope information may include the slope angle, the absolute value of the slope angle, and the position information corresponding to the slope. As an exemplary embodiment, the slope information of the road section to be traveled can be obtained through GPS information, or can be obtained through other optional methods, which are not specifically limited in this embodiment; by obtaining the slope information of the road section to be traveled, different road conditions can be judged based on different slope information, thereby determining the corresponding neutral coasting strategy based on different road conditions.

[0031] For the technical solution in step S204, the ramp attribute information of the road section to be traveled is determined according to the slope information, and the ramp attribute information includes the slope value and the ramp position information. As an exemplary embodiment, the ramp attribute information may also include road conditions, traffic conditions, the number of curves, the turning angle of the curves, altitude, road conditions, etc. In the present application, the slope value and the ramp position information will affect the determination of the neutral coasting strategy. It is understandable that the road conditions, traffic conditions, the number of curves, the turning angle of the curves, altitude, and road conditions will also individually or comprehensively affect the determination of the neutral coasting strategy.

[0032] It can be understood that a whole section of the road to be traveled may not only include one downhill slope, but may also include several downhill slopes or a combination of downhill slopes and flat slopes. Based on this, the ramp position information in the ramp attribute information may include the distribution of slopes, the positions of different slope intervals in the road section; and also include the position information of a slope such as the starting position and the ending position.

[0033] For the technical solution in step S206, after determining the ramp attribute of the road section to be driven according to the slope information, the neutral coasting strategy of the road section to be driven is determined according to the ramp attribute. When the corresponding ramp attributes are different, the neutral coasting strategy is also different. As an exemplary embodiment, under the slope attribute information with a small slope value and / or good road conditions, good traffic conditions, a small number of bends, a small turning angle of the bends, a low altitude, and good road conditions, the vehicle will not lose control due to the steep slope, so the road of the road section to be driven can be fully utilized for neutral coasting. At this time, in order to prevent the phenomenon of vehicle loss of control due to neutral coasting, the conditions for starting neutral coasting need to be appropriately restricted. Optionally, at a preset distance from the road section to be driven, if the accelerator pedal opening is less than the preset opening value and the vehicle speed is less than the preset vehicle speed value, the neutral coasting function can be activated to use the inertia of the vehicle to complete the driving of the road section to be driven.

[0034] Under the slope attribute information of large slope value and / or poor road condition, poor traffic condition, large number of curves, large turning angle of curves, high altitude and poor road condition, neutral gear coasting while driving may cause a sudden increase in vehicle speed and cause the vehicle to lose control. Therefore, optionally, when the road condition is a steep slope, a neutral gear coasting prohibition strategy is executed at the second preset distance before downhill to prevent the vehicle from losing control due to a sudden increase in vehicle speed caused by neutral gear coasting.

[0035] As an exemplary embodiment, after determining the neutral coasting strategy of the road section to be traveled based on the ramp attributes, the method includes: obtaining vehicle status information when entering the slope of the road section to be traveled; the vehicle status information includes throttle opening and / or vehicle speed; determining whether to activate neutral coasting based on the slope value and the vehicle status information, wherein the throttle opening and / or the vehicle speed required to activate neutral coasting are inversely correlated with the slope value.

[0036] For the above technical solution, after obtaining the vehicle state information when entering the road section to be driven, it is determined whether to activate neutral coasting based on the slope value and the vehicle state information after obtaining the vehicle state. As an exemplary embodiment, under the slope attribute information of small slope value and / or good road condition, good traffic condition, small number of curves, small turning angle of curves, low altitude and good road condition, the vehicle will not lose control due to descending steep slope, so the road section to be driven can be fully utilized for neutral coasting. At this time, in order to prevent the vehicle from losing control due to neutral coasting, the conditions for starting neutral coasting need to be appropriately restricted. Optionally, at a preset distance from the road section to be driven, if the accelerator pedal opening is greater than the preset opening value or the vehicle speed is greater than the preset vehicle speed value, the neutral coasting function can be stopped to prevent the vehicle from losing control due to the sudden increase in vehicle speed caused by neutral coasting.

[0037] It is understandable that when the slope value increases, the vehicle will be more and more likely to lose control due to a sudden increase in vehicle speed caused by coasting in neutral, and the speed will be faster. When the slope value increases, in order to prevent the vehicle from losing control due to a sudden increase in vehicle speed caused by coasting in neutral, the condition for triggering coasting in neutral will be changed to be more stringent, that is, the throttle opening and / or the vehicle speed value required to activate coasting in neutral will be reduced.

[0038] It can be understood that the above-mentioned slope value can also be other influencing factors in the ramp attribute information, including road conditions, traffic conditions, number of curves, turning angles of curves, altitude, road conditions, etc., which may affect the throttle opening and / or vehicle speed value, and no specific restrictions are made here.

[0039] As an exemplary embodiment, determining the neutral gliding strategy of the section to be traveled on based on the ramp attributes includes: judging whether the slope value is less than a first preset slope value; when the slope value is less than the first preset slope value, determining that neutral gliding can be performed on the section to be traveled; when the slope value is greater than the first preset slope value, determining that neutral gliding is prohibited on the section to be traveled.

[0040] For the above technical solution, when the slope value is greater than the first preset slope value, it indicates that the vehicle may lose control due to a sudden increase in vehicle speed caused by neutral coasting when driving on the section to be driven. Therefore, when the slope value is greater than the first preset slope value, it is determined to execute the strategy of prohibiting neutral coasting on the section to be driven.

[0041] It is understandable that the situation where the slope value is greater than the first preset slope value can also be determined based on the slope attribute information of the road condition, traffic condition, number of bends, turning angle of the bend, altitude, road condition, etc. For example, for the slope attribute information of the road condition, traffic condition, road condition, etc. that cannot be determined by data, the critical characterization value of the road condition, traffic condition, and road condition can be comprehensively determined by a mathematical model and a statistical algorithm. When the current road condition, traffic condition, and road condition information are greater than the critical characterization value, it indicates that the vehicle may be out of control due to a sudden increase in vehicle speed caused by neutral sliding when driving on the road section to be driven. Based on this, when the current road condition and / or traffic condition and / or road condition information are greater than the corresponding critical characterization value, it is determined that the neutral sliding strategy is to be executed on the road section to be driven. For the slope attribute information of the number of bends, the turning angle of the bends, and the altitude that can be determined by data, it can be determined whether the neutral sliding strategy is to be executed on the road section to be driven by presetting the preset value of the number of bends, the preset value of the turning angle of the bends, and the preset value of the altitude. For example, when the number of curves is greater than the preset value of the number of curves and / or the turning angle of the curve is greater than the preset value of the turning angle of the curve and / or the altitude is greater than the preset value of the altitude, it indicates that a sudden increase in vehicle speed due to neutral coasting may occur when driving on the section to be driven, resulting in vehicle loss of control, and it is determined to execute a strategy prohibiting neutral coasting on the section to be driven.

[0042] As an exemplary embodiment, when the slope value is less than the first preset slope value, the throttle opening when entering the ramp of the road section to be traveled is obtained; it is determined whether the throttle opening when entering the ramp of the road section to be traveled is less than the first preset throttle opening; when the throttle opening when entering the ramp of the road section to be traveled is less than the first preset throttle opening, the neutral coasting signal is activated.

[0043] For the above technical solution, when the slope value is less than the first preset slope value, it indicates that when driving on the road section to be driven, when the throttle opening is small, there will be no problem of vehicle speed increase caused by neutral coasting and thus causing the vehicle to lose control. Based on this, a throttle opening value can be preset as the first preset throttle opening, and when the slope value is less than the first preset slope value and the throttle opening value is less than the first preset throttle opening, the neutral coasting operation will not cause the vehicle speed increase caused by neutral coasting and thus causing the vehicle to lose control, and the neutral coasting signal can be activated to perform the neutral coasting operation.

[0044] It is understandable that the situation where the slope value is less than the first preset slope value can also be determined based on the slope attribute information of the road condition, traffic condition, number of bends, turning angle of the bend, altitude, road condition, etc. For example, for the slope attribute information of the road condition, traffic condition, road condition, etc. that cannot be determined by data, the critical characterization value of the road condition, traffic condition, and road condition can be comprehensively determined by mathematical models and statistical algorithms. When the current road condition, traffic condition, and road condition information are less than the critical characterization value, it indicates that there will be no sudden increase in vehicle speed caused by neutral sliding when driving on the road section to be driven, thereby causing the vehicle to lose control. Based on this, when the current road condition and / or traffic condition and / or road condition information are less than the corresponding critical characterization value and the throttle opening value is less than the first preset throttle opening, the neutral sliding signal can be activated to perform the neutral sliding operation. For the slope attribute information of the number of bends, turning angle of the bends, altitude, etc. that can be determined by data, it can be determined whether to execute the neutral sliding prohibition strategy on the road section to be driven by presetting the preset value of the number of bends, the preset value of the turning angle of the bends, and the preset value of the altitude. For example, when the number of curves is less than the preset value of the number of curves and / or the turning angle of the curve is less than the preset value of the turning angle of the curve and / or the altitude is less than the preset altitude and / or the throttle opening value is less than the first preset throttle opening, it indicates that there will be no sudden increase in vehicle speed due to neutral coasting when driving on the road section to be driven, which will cause the vehicle to lose control. The neutral coasting signal can be activated to perform the neutral coasting operation.

[0045] As an exemplary embodiment, when the slope value is less than the first preset slope value, it is determined whether the slope value is greater than a second preset slope value; when the slope value is greater than the second preset slope value, the vehicle speed when entering the ramp of the road section to be traveled is obtained; it is determined whether the vehicle speed when entering the ramp of the road section to be traveled is less than the preset vehicle speed value; when the vehicle speed value is less than the preset vehicle speed value, the neutral coasting signal is activated.

[0046] For the above technical solution, the situation where the slope value is less than the first preset value is further divided. When the slope value is less than the first preset slope value, it is determined whether the slope value is greater than the second preset slope value. When the slope value is greater than the second preset slope value, it can be represented that when the vehicle speed is too fast when entering the ramp of the road section to be driven, due to the presence of a certain slope in the road section to be driven, there will be a problem of vehicle loss of control caused by a sudden increase in vehicle speed due to coasting in neutral gear. Based on this, when the slope value is greater than the second preset slope value, it is determined whether the vehicle speed when entering the ramp of the road section to be driven is less than the preset vehicle speed value. When the slope value is greater than the second preset slope value and the vehicle speed is less than the preset vehicle speed value, it can be represented that when driving on the road section to be driven, there will be no problem of vehicle loss of control caused by a sudden increase in vehicle speed due to coasting in neutral gear. When the slope value is greater than the second preset slope value and the vehicle speed is greater than the preset vehicle speed value, it may indicate that when driving on the road section to be driven, there may be a problem of vehicle loss of control caused by a sudden increase in vehicle speed due to coasting in neutral gear.

[0047] As an exemplary embodiment, when the slope value is greater than the first preset slope value, the corresponding gear is selected based on the slope value.

[0048] With respect to the above technical solution, when the slope value is greater than the first preset slope value, it indicates that the vehicle may lose control due to a sudden increase in vehicle speed caused by coasting in neutral gear when driving on the road section to be driven. In order to prevent the vehicle from losing control due to a sudden increase in vehicle speed caused by coasting in neutral gear, braking measures can be taken according to the corresponding gear selected based on the slope value. For example, when the slope value is larger, a lower gear can be selected based on the slope value. When the vehicle is in a low gear, the engine will bring about a braking effect to prevent the vehicle from losing control due to a sudden increase in vehicle speed caused by coasting in neutral gear.

[0049] As an exemplary embodiment, after determining the neutral coasting strategy of the road section to be traveled according to the ramp attributes, the method includes: acquiring the current position information of the vehicle; determining a prohibited neutral coasting point based on the vehicle position information and the slope position information; and when the vehicle reaches the prohibited neutral coasting point, confirming that the neutral coasting strategy is prohibited neutral coasting.

[0050] In view of the above technical solution, in order to prevent the vehicle from losing control due to a sudden increase in vehicle speed caused by neutral coasting when the slope is too large. After obtaining the current position information of the vehicle, the position information corresponding to the slope whose slope value is greater than the first preset value is obtained, and the neutral coasting prohibited point is determined based on the current position information of the vehicle and the position information corresponding to the slope. As an exemplary embodiment, the neutral coasting point may be a point at a second preset distance from the slope position information. When the vehicle is at the second preset distance from the slope position, it indicates that the vehicle has reached the prohibited coasting point. At this time, the neutral coasting strategy is determined to prohibit neutral coasting, and a signal indicating that neutral coasting is prohibited is output. The problem of vehicle loss of control due to descending a steep slope will not occur, thereby improving safety.

[0051] As an exemplary embodiment, determining the neutral coasting strategy of the road section to be traveled based on the ramp attributes includes: dividing the road section to be traveled into multiple slope intervals according to the slope information; and determining the neutral coasting strategy corresponding to each slope interval in the road section to be traveled based on the slope values ​​of the slope intervals.

[0052] With respect to the above technical solution, it can be understood that a whole section of the road to be traveled may not only include one downhill slope, but may also include a combination of several downhill slopes or downhill slopes and flat slopes. Based on this, the ramp position information in the ramp attribute information may include the distribution of the slope, the position of different slope intervals in the road section; and also include the position information of a slope such as the starting position and the ending position. Based on this, as an optional embodiment, the average slope corresponding to each downhill slope at the starting position and the ending position is calculated for the starting position and the ending position of the slope, and different neutral sliding strategies in the above scheme are specifically executed for different average slopes. The slope change rate of the current slope can be calculated, and the slope change rate is used as a distinction, and the intervals with a slope change rate greater than the preset value of the slope change rate are taken as different multiple intervals, so as to determine multiple intervals with different slope values ​​and different slope change rates, and the different neutral sliding strategies in the above scheme are specifically executed for each interval with different slope values. The contour lines of the road section to be traveled can be obtained based on GPS, the road section to be traveled within the contour line interval is used as a plurality of different slope intervals, and different neutral gear coasting strategies in the above scheme are specifically executed for each different slope interval.

[0053] It can be understood that the slope value can also be other influencing factors such as road conditions, traffic conditions, number of curves, turning angles of curves, altitude, road conditions, etc. that can be divided into intervals and will affect the neutral gliding strategy, and no specific restrictions are made here.

[0054] It can be understood that the targeted execution of the neutral coasting strategy for multiple intervals with different slope values ​​can maximize the use of the vehicle's kinetic energy to complete downhill driving and reduce fuel consumption.

[0055] Through the above technical solution, the neutral gliding strategy for the road section to be driven according to the slope attribute includes: dividing the road section to be driven into multiple slope intervals according to the slope information; determining the neutral gliding strategy corresponding to each slope interval in the road section to be driven according to the slope value of the slope interval, which solves the problem of the neutral gliding strategy for downhill in the prior art, which can only be performed when the accelerator pedal opening is zero. When the slope information ahead cannot be perceived, the neutral gliding speed needs to be limited to prevent the problem of vehicle loss of control due to steep downhill, so as to achieve the effect of being able to maximize the use of the vehicle's kinetic energy to complete downhill driving and reduce fuel consumption.
