For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0053] Figure 2 is a structural schematic diagram of the vehicle creep control device provided by an embodiment of this application;

[0054] Figure 3 is a structural schematic diagram of the electronic device provided by an embodiment of this application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following will clearly and completely describe the technical solutions in this application with reference to the drawings in this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in this application belong to the scope of protection of this application.

[0056] An embodiment of this application provides a vehicle creep control method, and its execution subject can be an electronic device. For example, it can be a controller. The following will be described by taking the execution subject of this method as a controller as an example. Figure 1 is a flowchart of the vehicle creep control method provided by an embodiment of this application. Referring to Figure 1 , this method may include:

[0057] Step 110: When the creep mode of the vehicle is turned on, obtain the road condition information of the target road section in front of the vehicle in the driving direction and the status information of the vehicle; the road condition information includes the average vehicle speed within the road section, and the status information includes the driving speed of the vehicle;

[0058] Step 120: Determine the road segment type of the target road segment based on at least one of the road condition information and the status information.

[0059] Step 130: If the road segment type is a congestion type or a parking type, the first distance between the vehicle and the target road segment is less than the first distance threshold, and the driving speed is higher than the average speed within the road segment, control the creep parameters of the vehicle based on the road segment type; the creep parameters include a creep speed parameter and / or a creep mode start / stop parameter.

[0060] In step 110, when the creep mode of the vehicle is turned on, the controller can obtain the road condition information of the target road segment in front of the vehicle's driving direction and the status information of the vehicle. Specifically, the target road segment is a section of road that the vehicle is about to drive on. Both the road condition information of the target road segment and the status information of the vehicle can be real-time information obtained at any time as the vehicle drives. The road condition information can be obtained from the vehicle's navigation module, and the status information can be obtained from the vehicle control module. The road condition information can include the average speed within the road segment, thereby reflecting the overall driving speed of the target road segment. The status information can include the driving speed of the vehicle (this vehicle).

[0061] In step 120, the controller can determine the road segment type of the target road segment based on at least one of the road condition information and the status information. Specifically, the road segment type can be used to characterize the congestion situation of the target road segment.

[0062] In step 130, if the road segment type of the target road segment is a congestion type or a parking type, the first distance between the vehicle and the target road segment is less than the first distance threshold (e.g., 20 m), and the driving speed of the vehicle is higher than the average speed within the target road segment, the controller can control the creep parameters of the vehicle based on the road segment type.

[0063] Specifically, when the vehicle is far from the target road segment, the controller can obtain the first distance between the vehicle and the target road segment through the in-vehicle navigation module. When the vehicle drives to a position close to the target road segment before reaching it, the controller can obtain the first distance between the vehicle and the target road segment through the in-vehicle radar module, and the accuracy of the first distance at this time is higher. The controller can control the creep parameters of the vehicle in advance when the first distance between the vehicle and the target road segment decreases to less than the first distance threshold and the vehicle has not reached the target road segment yet. For example, control the creep speed parameter and / or the creep mode start / stop parameter of the vehicle. The creep speed parameter characterizes the creep speed of the vehicle, and the creep mode start / stop parameter characterizes whether the creep mode of the vehicle is turned on or off. It should be noted that the creep mode of the vehicle is default to be turned on.

[0064] The vehicle creep control method provided by the embodiments of the present application determines the road section type of the target road section through road condition information and status information. When the road section type is a congestion type or a stop type, the creep of the vehicle is controlled based on the road section type. Before the vehicle reaches the target road section, the creep of the vehicle can be adjusted in advance based on the road section type, improving the intelligence level of the creep mode, enabling the vehicle to adapt to the real-time road conditions of the front road section in a timely manner, reducing the number of manual operations of the driver on the brakes and accelerator of the vehicle, reducing the vehicle control difficulty, and saving the driving cost.

[0065] In some embodiments, the road condition information further includes the road section length of the target road section and the road section status information on whether the target road section is congested; determining the road section type of the target road section based on at least one of the road condition information and the status information includes: if the road section status information is congested, the road section length is greater than a first length threshold, and the average vehicle speed within the road section is lower than a first speed threshold, determining that the road section type of the target road section is a congestion type.

[0066] If the road section status information is congested, the road section length is greater than a first length threshold (e.g., 100 m), and the average vehicle speed within the road section is lower than a first speed threshold (e.g., 10 km / h), the controller can determine that the road section type of the target road section is a congestion type. The parking probability of the target road section of the congestion type is relatively small.

[0067] The vehicle creep control method provided by the embodiments of the present application determines the road section type of the target road section through road condition information, and based on the road section type, controls the creep parameters of the vehicle. Before the vehicle reaches the target road section, the creep of the vehicle can be adjusted in advance based on the road section type of the target road section, improving the intelligence level of the creep mode, enabling the vehicle to adapt to the real-time road conditions of the target road section in a timely manner, reducing the number of operations of the driver on the brakes and accelerator of the vehicle, reducing the vehicle control difficulty, and saving the driving cost.

[0068] In some embodiments, controlling the creep parameters of the vehicle based on the road section type includes: if the road section type is a congestion type and the average vehicle speed within the road section is greater than or equal to a second speed threshold, determining a creep speed parameter smaller than the average vehicle speed within the road section according to the average vehicle speed within the road section, and controlling the creep speed of the vehicle with the creep speed parameter; if the road section type is a congestion type and the average vehicle speed within the road section is lower than the second speed threshold, determining that the creep mode start-stop parameter is to stop the creep mode, and adjusting the driving vehicle speed to zero.

[0069] If the road segment type of the target road segment is the congestion type and the average vehicle speed within the road segment is greater than or equal to the second speed threshold (e.g., 1 km / h), the controller can determine a creep speed parameter less than the average vehicle speed within the road segment based on the average vehicle speed within the road segment, and then control the vehicle to creep at the creep speed parameter. For example: when the average vehicle speeds within the road segment are 10 km / h, 8 km / h, 6 km / h, 4 km / h, and 2 km / h in sequence, the creep speed parameters can be 9.5 km / h, 7.5 km / h, 5.5 km / h, 3.5 km / h, and 1.5 km / h in sequence. The determined creep speed parameter will be displayed on the main instrument of the vehicle to prompt the driver.

[0070] If the road segment type of the target road segment is the congestion type and the average vehicle speed within the road segment is less than the second speed threshold (e.g., 1 km / h), stop the creep mode and adjust the driving speed to zero.

[0071] The vehicle creep control method provided by the embodiments of the present application adjusts the creep speed parameter or stops the creep mode based on the average vehicle speed within the road segment when the road segment type of the target road segment is the congestion type, improves the intelligence level of the creep mode, enables the vehicle to adapt to the real-time road conditions of the target road segment in a timely manner, reduces the number of operations of the driver on the brake and accelerator of the vehicle, reduces the vehicle control difficulty, and saves the driving cost.

[0072] In some embodiments, the road condition information further includes the second distance between the target traffic light in the target road segment and the vehicle, and the timing information of the target traffic light; determining the road segment type of the target road segment based on at least one of the road condition information and the status information includes: determining a first duration based on the second distance and the average vehicle speed within the road segment; the first duration is the expected duration required for the vehicle to reach the position of the target traffic light; determining a second duration that the vehicle needs to wait after reaching the position of the target traffic light based on the first duration and the timing information; if the second duration is greater than the preset duration, determining that the road segment type of the target road segment is the stop type.

[0073] Specifically, the target traffic light is the traffic light closest to the vehicle in the target road segment. The timing information of the target traffic light mainly includes the color of the traffic light and the countdown of the current color. The stop type means that the vehicle has a high probability of stopping in the target road segment.

[0074] The controller can divide the second distance by the average vehicle speed within the road section to obtain the first duration, which is the expected required duration for the vehicle to reach the position where the target traffic light is located. The controller can determine the second duration that the vehicle needs to wait after reaching the position where the target traffic light is located based on the first duration and the timing information. If the second duration is greater than the preset duration, it can be determined that the road section type of the target road section is the parking type. The parking probability of the target road section with the parking type is relatively high. When the road section type is the parking type, the parking probability of the vehicle within the target road section is greater than the parking probability of the vehicle within the target road section when the road section type is the congestion type.

[0075] For example: The second distance between the vehicle and the target traffic light is 100m, the average vehicle speed within the road section is 36 km / h, the target traffic light is red, and the countdown of the red light remains 30s. Calculate the first duration as 10s, determine the second duration as 20s, which is greater than the preset duration (such as: 5s), and judge that the road section type of the target road section is the parking type.

[0076] The vehicle creep control method provided by the embodiments of the present application determines the road section type of the target road section through road condition information, and then controls the creep of the vehicle based on the road section type. It can adjust the creep of the vehicle in advance based on the road section type before the vehicle reaches the target road section, improving the intelligence level of the creep mode, enabling the vehicle to adapt to the real-time road conditions of the target road section in a timely manner, reducing the operation times of the driver on the brake and accelerator of the vehicle, reducing the vehicle control difficulty, and saving the driving cost.

[0077] In some embodiments, the vehicle creep control method further includes: obtaining the historical parking information of the vehicle; determining the road section type of the target road section based on at least one of the road condition information and the status information, including: if the historical parking information indicates that the parking probability of the vehicle in the target road section within a fixed time period is greater than the preset probability, and it is determined based on the driving vehicle speed that the vehicle will pass through the target road section within the fixed time period, it is determined that the road section type of the target road section is the parking type.

[0078] Specifically, the controller can determine that the parking probability of the vehicle in the target road section within a fixed time period is greater than the preset probability based on the historical parking information of the vehicle. It can also simultaneously obtain the vehicle gear information and the vehicle door status information corresponding to the historical parking information of the vehicle, so as to assist in judging the parking probability of the vehicle in the target road section. For example, if the vehicle has a high-frequency stop in the target road section during the period from 17:00 to 18:00 on weekdays and the gear is switched to the P gear or there is a door opening / closing action, it can be judged that the parking probability of the vehicle in the target road section within the fixed time period is greater than the preset probability. At this time, if it is determined based on the driving vehicle speed of the vehicle that the vehicle will pass through the target road section within the fixed time period, it can be determined that the road section type of the target road section is the parking type. That the target road section is of the parking type indicates that the parking probability of the vehicle within the target road section is relatively high.

[0079] The vehicle creep control method provided by the embodiment of the present application determines the road section type of the target road section through the status information, and then controls the creep of the vehicle based on the road section type. It can adjust the creep of the vehicle in advance based on the road section type before the vehicle reaches the target road section, improving the intelligence level of the creep mode, enabling the vehicle to adapt to the real-time road conditions of the target road section in a timely manner, reducing the number of operations of the driver on the brakes and accelerator of the vehicle, reducing the vehicle control difficulty, and saving the driving cost.

[0080] In some embodiments, controlling the creep parameters of the vehicle based on the road section type includes: if the road section type is a parking type, determining that the creep mode start / stop parameter is to stop the creep mode and adjusting the driving speed to zero.

[0081] If the controller determines that the road section type of the target road section is a parking type, it can stop the creep mode of the vehicle and adjust the driving speed of the vehicle to zero.

[0082] The vehicle creep control method provided by the embodiment of the present application stops the creep mode and adjusts the driving speed of the vehicle to zero when the road section type of the target road section is a parking type, improving the intelligence level of the creep mode, enabling the vehicle to adapt to the real-time road conditions of the target road section in a timely manner, reducing the number of operations of the driver on the brakes and accelerator of the vehicle, reducing the vehicle control difficulty, and saving the driving cost.
