[0022] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0023] It should be clear that the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0024] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0025] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0026] The steep slope descent function in the vehicle usually monitors the downhill state and the vehicle slip risk in real time through sensors (such as wheel speed sensors, acceleration sensors, etc.) in the vehicle. When the vehicle is downhill, the vehicle speed when downhill can be automatically controlled, and the brake force is applied to the wheels, so that the user can smoothly pass through the downhill slope section without stepping on the brake pedal. In order to improve the driving safety and comfort during downhill, it is usually necessary to turn on the steep slope descent function before downhill.

[0027] At present, it is usually necessary for the user to manually open the physical switch or virtual switch of the steep slope descent function to turn on the steep slope descent function. If the user does not manually turn on the steep slope descent function in advance, it may be necessary to operate the physical switch or virtual switch to turn on the steep slope descent function during downhill, which may have driving risks and reduce the driving safety and comfort to some extent. In addition, the virtual switch of the steep slope descent function of some vehicles may be in the secondary menu of the vehicle system, which is less convenient for the user to operate.

[0028] To solve the above problems, in the embodiment of the present application, first, the first driving position of the vehicle is acquired; second, when the first driving position is the same as the path position corresponding to the pre-stored recording route, the second driving position of the vehicle is acquired; then, the target recording route is determined according to the second driving position; finally, the speed of the vehicle is controlled according to the speed information corresponding to the target recording route. In other words, when the vehicle drives to the path position of the pre-stored recording route, the steep slope slow descent function in the vehicle is activated, so that the speed of the vehicle can be automatically controlled. The user does not need to be distracted to operate the physical switch or the virtual switch to turn on the steep slope slow descent function, which improves the driving safety and comfort to a certain extent. In addition, the user does not need to manually operate the physical switch or the virtual switch to use the steep slope slow descent function, thereby improving the convenience of using the steep slope slow descent function.

[0029] Specifically, the following detailed description is made in combination with the accompanying drawings and specific embodiments.

[0030] Reference is made to Figure 1 A flowchart of a steep slope slow descent control method provided in the embodiment of the present application is shown in FIG. 1. As shown in FIG. 1, the method specifically includes steps S101 to S104. Figure 1

[0031] Step S101: Acquire the first driving position of the vehicle.

[0032] It can be understood that the first driving position is the geometric position of the vehicle when driving on the road. For example, the first driving position P1 of the vehicle can be represented by spatial coordinates (a1, b1, c1), wherein a1 represents the latitude of the first driving position P1, b1 represents the longitude of the first driving position P1, and c1 represents the altitude of the first driving position P1.

[0033] Of course, the first driving position can also be represented by other ways by the person skilled in the art, which is not specifically limited in the embodiment of the present application.

[0034] In the embodiment of the present application, in order to determine the timing of activating the steep slope slow descent function, the first driving position of the vehicle needs to be acquired to determine whether the vehicle drives to the road section where the speed needs to be automatically controlled. It can be understood that the positioning module is usually provided in the vehicle, which can determine the first driving position of the vehicle by collecting the positioning data of the vehicle.

[0035] Step S102: When the first driving position is the same as the path position corresponding to the pre-stored recording route, acquire the second driving position of the vehicle.

[0036] It can be understood that the pre-stored recording route refers to the road section where the speed of the vehicle needs to be automatically controlled. In the embodiment of the present application, the path position corresponding to the pre-stored recording route and the speed corresponding to the path position need to be stored first to determine the timing of activating the steep slope slow descent function. ​

[0037] In a possible implementation, a plurality of path positions of a pre-stored recorded route and a vehicle speed corresponding to each path position during vehicle driving are recorded.

[0038] Specifically, on a road section where the vehicle needs to be automatically controlled in speed, the steep slope slow descent function is manually started, a plurality of path positions of a pre-stored recorded route and a vehicle speed corresponding to each path position during vehicle driving are recorded, and the pre-stored recorded route corresponding to the road section is generated and stored in a storage module of the vehicle.

[0039] It should be noted that during vehicle driving, the user can adjust the vehicle speed through the accelerator pedal or the brake pedal. At this time, the vehicle records the adjusted vehicle speed and the path position corresponding to the vehicle speed.

[0040] In the embodiment of the present application, the i-th path position of the s-th pre-stored recorded route L s may be represented as { (Q s 1, V s 1), (Q s 2, V s 2), …, (Q s n , V s n}. Q s i represents the i-th path position of the s-th pre-stored recorded route L s , and V s represents the vehicle speed corresponding to the i-th path position of the s-th pre-stored recorded route L s , i≤n.

[0041] wherein the i-th path position Q s i of the s-th pre-stored recorded route L s i may also be represented by spatial coordinates (x s i , y s i ), x s i represents the latitude of the i-th path position of the s-th pre-stored recorded route L s , y s i represents the longitude of the i-th path position of the s-th pre-stored recorded route L s , and z s i represents the altitude of the i-th path position of the s-th pre-stored recorded route L s .

[0042] Of course, the skilled person in the art can also express the path position in other ways, and the embodiments of the present application do not make specific limitations in this regard. It should be noted that, in order to facilitate comparison of whether the first driving position and the path position are the same, it is necessary to ensure that the first driving position and the path position are expressed in the same way.

[0043] In the embodiments of the present application, when the first driving position is the same as the path position corresponding to the pre-recorded route, it can be considered that the vehicle needs to be automatically controlled in speed. At this time, it is necessary to activate the steep slope slow descent function to realize automatic control of speed. For example, the first driving position is (a1, b1, c1), and the pre-recorded route L s The i-th path position Q s i of the pre-recorded route L s i is (x s , y i , z s i ). When a1=x s i , b1=y s i , and c1=z s i , it can be considered that the vehicle travels to a downhill section that needs to be automatically controlled in speed, and the steep slope slow descent function is activated.

[0044] However, the path position that is the same as the first driving position can be a path position corresponding to different pre-recorded routes. For example, the path position Q (x, y, z) that is the same as the first driving position is the i-th path position of the pre-recorded route L1 and the j-th path position of the pre-recorded route L2. Therefore, in the embodiments of the present application, the second driving position of the vehicle needs to be obtained to determine the driving route of the vehicle, and then determine the speed of the vehicle that is automatically controlled.

[0045] It can be understood that the vehicle travels from the first driving position to the second driving position. The second driving position is the geometric position of the vehicle when it travels on the road. For example, the second driving position P2 of the vehicle can be expressed by the spatial coordinates (a2, b2, c2), wherein a2 represents the latitude of the second driving position P2, b2 represents the longitude of the second driving position P2, and c2 represents the altitude of the second driving position P2.

[0046] It should be noted that the skilled person in the art can also express the second driving position in other ways, and the embodiments of the present application do not make specific limitations in this regard. Of course, the second driving position and the expression of the second driving position also need to have a unified standard.

[0047] In the embodiments of the present application, the positioning data of the vehicle can be collected by the positioning module described above to determine the second driving position of the vehicle.

[0048] In practical application, the user usually expects the steep slope descent function of the vehicle to be activated before the downhill, so as to automatically control the vehicle speed during the downhill, instead of activating the steep slope descent function during the downhill of the vehicle.

[0049] In a possible implementation, the second driving position of the vehicle is acquired when the first driving position is the same as an initial path position corresponding to the pre-stored recorded route.

[0050] It can be understood that the initial path position is the first path position corresponding to the pre-stored recorded route. For example, the pre-stored recorded route L1 is { (Q 1 1, V 1 1), (Q 1 2, V 1 2), …, (Q 1 n , V 1 n} and the path position Q 1 1 is the first path position corresponding to the pre-stored recorded route L1.

[0051] In the embodiments of the present application, when the first driving position is the same as the initial path position corresponding to the pre-stored recorded route, it can be considered that the vehicle speed needs to be automatically controlled. At this time, the steep slope descent function is activated to realize the automatic control of the vehicle speed. For example, the first driving position is (a1, b1, c1) and the first path position Q 1 1 of the pre-stored recorded route L1 is (x 1 1, y 1 1, z 1 1). When a1=x 1 1, b1=y 1 1 and c1=z 1 1, it can be considered that the vehicle drives to the downhill section that needs to be automatically controlled, and the steep slope descent function is activated.

[0052] It can be understood that the steep slope descent function is activated before the vehicle passes through the section corresponding to the pre-stored recorded route, so as to automatically control the vehicle speed during the whole downhill, instead of activating the steep slope descent function during the process that the vehicle passes through the section corresponding to the pre-stored recorded route. Thus, the user does not need to reduce the vehicle speed through the brake pedal when the vehicle drives on the section corresponding to the pre-stored recorded route, and only needs to focus on controlling the steering wheel, which improves the driving safety and the simplicity of the user operation to a certain extent.

[0053] Step S103: determining a target recorded route according to the second driving position.

[0054] It can be understood that the second driving position is a path position recorded only in the target recorded route.

[0055] Therefore, the target recorded route can be determined according to the second driving position. Specifically, the second driving position is compared with the path positions in each of the pre-stored recorded routes, and the pre-stored recorded route having the same path position as the second driving position is the target recorded route.

[0056] Referring to Figure 2 , a schematic diagram of a road is provided for the embodiments of the present application. In Figure 2 , a road L1 and a road L2 are shown, and the arrow direction in the middle of the road is the road passing direction. The pre-stored recorded route corresponding to the road L1 is { (Q 1 1, V 1 1), (Q 1 2, V 1 2), …, (Q 1 n , V 1 n ); and the pre-stored recorded route corresponding to the road L2 is { (Q s 1, V s 1), (Q s 2, V s 2), …, (Q s n , V s n}. When the vehicle drives to a point P2 of the road S1, a second driving position P2 (a2, b2, c2) can be obtained. The second driving position P2 (a2, b2, c2) is only a path position in the pre-stored recorded route corresponding to the road L1. Therefore, it can be determined that the target recorded route is the pre-stored recorded route corresponding to the road L1.

[0057] Step S104: controlling the vehicle speed according to the vehicle speed information corresponding to the target recorded route.

[0058] It can be understood that the vehicle speed information corresponding to the target recorded route includes the vehicle speed corresponding to the second driving position and the vehicle speed corresponding to the path position after the second driving position. For example, the target recorded route is { (Q 1 1, V 1 1), (Q 1 2, V 1 2), …, (Q 1 n , V 1 n}. When the second driving position is Q 1 2, the vehicle speed information corresponding to the target recorded route includes V 1 2, V 1 3, …, V 1 n .

[0059] In the embodiment of the present application, after the target recorded route is determined, the vehicle needs to automatically control the vehicle speed according to the vehicle speed corresponding to the path position in the target recorded route, so that the vehicle travels according to the vehicle speed in the target recorded route.

[0060] In order for the user to know in time whether the steep slope slow descent is activated, so that the user can not step on the brake pedal and focus on controlling the steering wheel, the driving safety and comfort are improved. In a possible implementation, the vehicle speed is controlled according to the vehicle speed information corresponding to the target recorded route, and the activation information is output.

[0061] It can be understood that the activation information is used to prompt the user that the steep slope slow descent function has been activated. The vehicle can output the exit information in various ways. For example, the indicator light set on the control instrument is turned on, the broadcast voice of "the steep slope slow descent function has been activated" is output, etc. Of course, those skilled in the art can set other output ways of the activation information according to actual needs. The embodiment of the present application does not make specific limitation on this.

[0062] In the embodiment of the present application, first, the first driving position of the vehicle is acquired; second, when the first driving position is the same as the path position corresponding to the pre-stored recorded route, the second driving position of the vehicle is acquired; then, the target recorded route is determined according to the second driving position; finally, the vehicle speed is controlled according to the vehicle speed information corresponding to the target recorded route. In other words, when the vehicle travels to the path position of the pre-stored recorded route, the steep slope slow descent function in the vehicle is activated, so as to automatically control the vehicle speed. The user does not need to operate the physical switch or the virtual switch to start the steep slope slow descent function, which improves the driving safety and comfort to a certain extent. In addition, the user can use the steep slope slow descent function without manually operating the physical switch or the virtual switch, thereby improving the convenience of using the steep slope slow descent function.

[0063] In order to make the vehicle exit the steep slope slow descent function, in a possible way, the method further includes: when the vehicle travels to the last path position corresponding to the target recorded route or receives a closing instruction sent by the user or the vehicle speed is greater than a preset vehicle speed threshold, the control on the vehicle is exited.

[0064] It can be understood that when the vehicle travels to the last path position corresponding to the target recorded route, it can be considered that the vehicle has traveled through the section where the vehicle speed needs to be automatically controlled, and at this time, the vehicle speed does not need to be controlled. For example, the target recorded route is { (Q 1 1, V 1 1), (Q 1 2, V 1 2), …, (Q 1 n , V 1 n}, and the last path position corresponding to the} is Q 1 n When the vehicle travels to Q 1 n , the vehicle has traveled through the road section corresponding to the target recorded route, and thus the control over the vehicle can be exited.

[0065] In the embodiment of the present application, when the vehicle activates the steep slope slow descent function, if the user does not need to use the steep slope slow descent function to automatically control the vehicle speed, a closing instruction can be sent to the vehicle to exit the control over the vehicle. For example, the closing instruction can be sent to the vehicle by closing a physical switch or a simulated switch, outputting a voice, and the like. Further, when the vehicle receives the closing instruction sent by the user, the control over the vehicle is exited.

[0066] It should be noted that the control over the vehicle can also be exited when the vehicle speed is greater than a preset vehicle speed threshold. It can be understood that, during the downhill process of the vehicle, the vehicle speed can become large due to the conversion of the gravitational potential energy of the vehicle into kinetic energy. Therefore, in most cases, the vehicle speed needs to be automatically controlled during the downhill process of the vehicle. At this time, in order to ensure smooth passing through the downhill road section, the vehicle speed needs to be automatically controlled to be less than a preset vehicle speed threshold. When the vehicle speed is greater than the vehicle speed threshold, it can be considered that the vehicle has traveled through the downhill road section that needs to be automatically controlled, and thus the vehicle speed does not need to be controlled.

[0067] The vehicle speed threshold is a preset value, for example, 50 kph, 55 kph, 60 kph, or the like. Of course, a person skilled in the art can set other vehicle speed thresholds according to actual needs. The embodiment of the present application does not make a specific limitation in this regard.

[0068] In the embodiment of the present application, by setting the exit condition of the steep slope slow descent function, the automatic exit of the steep slope slow descent function is realized, thereby improving the flexibility of using the steep slope slow descent function.

[0069] In order to enable the user to know in time whether the steep slope slow descent is exited, in a possible implementation manner, when the vehicle travels to the last path position corresponding to the target recorded route, or receives the closing instruction sent by the user, or the vehicle speed is greater than the preset vehicle speed threshold, the control over the vehicle is exited, and exit information is output.

[0070] It can be understood that the exit information is used to prompt the user that the steep slope slow descent function has been closed. The vehicle can output the exit information in various ways. For example, a light on the control instrument is turned off, a broadcast voice of “the steep slope slow descent function has been closed” is output, and the like. Of course, a person skilled in the art can set other output manners of the exit information according to actual needs. The embodiment of the present application does not make a specific limitation in this regard.

[0071] It should be noted that when the user closes the steep slope slow descending function through other ways after not completely driving through the last path position corresponding to the target recorded route, it can be considered that the user does not want to use the steep slope slow descending function on the road section corresponding to the target recorded route, and at this time, the vehicle will not activate the steep slope slow descending function. To some extent, the problem that the frequent activation of the steep slope slow descending function affects the user experience can be avoided.

[0072] As described above, the pre-recorded route is usually stored in the vehicle. In order to provide the user experience, in a possible implementation, in response to the pre-recorded route deletion operation triggered by the user, the path position corresponding to the pre-recorded route deletion operation and the vehicle speed corresponding to the path position are deleted.

[0073] In the embodiment of the application, the user can perform the pre-recorded route deletion operation through the display screen in the vehicle to determine the pre-recorded route to be deleted. Further, the path position corresponding to the pre-recorded route and the vehicle speed corresponding to the path position are deleted.
