However, for older models that did not come equipped with AH, adding this function requires hardware upgrades, which is quite challenging. Therefore, how to enable AH in vehicles without it is a technical problem that needs to be solved. Summary of the Invention

[0027] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0029] It should be understood that the steps described in the method embodiments of this disclosure may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this disclosure is not limited in this respect.

[0030] With the improvement of automotive R&D and manufacturing capabilities, more and more new models are equipped with automatic parking functions. However, some older models do not have automatic parking functions when they leave the factory. Only through hardware upgrades can automatic parking functions be added, which is quite difficult to implement. To address this issue, this disclosure provides an automatic parking method. The method obtains the vehicle's location information and acceleration through a global positioning system configured on a mobile terminal, determines the time when the parking brake needs to be activated based on the collected information, and sends a control signal to the vehicle to activate the parking brake. Automatic parking is achieved without hardware upgrades. The method is described below with reference to specific embodiments.

[0031] Figure 1 This is a flowchart of an automatic parking method provided in an embodiment of this disclosure. The method can be executed by an automatic parking device, which can be installed on a mobile terminal. Figure 1 As shown, the automatic parking method provided in this embodiment includes the following steps:

[0032] S101, The mobile terminal obtains the location information and acceleration of the vehicle it is in through the Global Positioning System.

[0033] In this embodiment of the disclosure, the automatic parking device can obtain the location information and acceleration of the vehicle where the mobile terminal is located in real time through the Global Positioning System (GPS) on the mobile terminal.

[0034] In one exemplary embodiment of this disclosure, the automatic parking device can obtain the location information of the vehicle at various times by using GPS on the mobile terminal, and then calculate the acceleration of the vehicle at various times based on the location information.

[0035] S102. Based on the positioning information, if the distance between the locations in two consecutively collected positioning information is less than a preset distance, the vehicle is in a stationary state.

[0036] The preset distance in this embodiment can be understood as a pre-set distance threshold. When the distance the vehicle moves within one collection cycle of the GPS system is less than the preset distance, it can be determined that the vehicle is stationary.

[0037] In this embodiment of the present disclosure, after obtaining the vehicle's location information via GPS, the automatic parking device can extract two location information from two consecutively collected location information, thereby determining the distance between the two locations, comparing it with a preset distance, and determining that the vehicle is in a stationary state when the distance between the two locations is less than the preset distance.

[0038] In one exemplary embodiment of the present disclosure, the automatic parking device can determine the location in the currently collected location information and the location in the previously collected location information after obtaining location information through GPS, and then determine the distance between the two locations, compare the distance with a preset distance, and determine that the distance is less than the preset distance, at which point the vehicle is in a stationary state.

[0039] S103. Based on the acceleration, determine whether the vehicle speed change within a preset time before the vehicle comes to a stop meets the conditions for activating the parking brake.

[0040] The preset time in this embodiment can be understood as a pre-set time period for determining whether the vehicle meets the conditions for opening the parking brake.

[0041] In this embodiment of the present disclosure, the automatic parking device can determine the vehicle speed change within a preset time before the vehicle comes to a stop after obtaining the vehicle's acceleration, and then compare the vehicle speed change with the preset parking brake activation conditions to determine that the vehicle speed change meets the preset parking brake activation conditions.

[0042] In one exemplary embodiment of the present disclosure, the automatic parking device can determine that the vehicle's acceleration is always negative for a preset time before the vehicle comes to a standstill, i.e., the vehicle is always in a deceleration state for a preset time before coming to a standstill, and then determine that the vehicle speed change meets the conditions for opening the parking brake.

[0043] S104. Send a control signal to the vehicle so that the vehicle activates the parking brake upon receiving the control signal.

[0044] The control signals in this embodiment can be understood as signals used to control the vehicle to activate the parking brake.

[0045] In this embodiment of the disclosure, after determining that the conditions for opening the parking brake are met, the automatic parking device can send a control signal to the vehicle where the mobile terminal is located through a pre-established communication connection with the vehicle, such as a Bluetooth connection, a Wi-Fi Peer-to-Peer (Wi-Fi P2P) connection, so that the vehicle can activate the parking brake in response to the control signal.

[0046] This embodiment of the disclosure uses a mobile terminal to obtain the location information and acceleration of the vehicle via a global positioning system. Based on the location information, it determines that the distance between two consecutively collected location information is less than a preset distance, indicating that the vehicle is stationary. Based on the acceleration, it determines that the vehicle speed change within a preset time before the vehicle came to a stop meets the conditions for activating the parking brake. A control signal is then sent to the vehicle so that it activates the parking brake upon receiving the control signal. This allows the mobile terminal to collect the vehicle's location information and acceleration, determine the moment when the parking brake needs to be activated based on the collected information, and send a control signal to activate the parking brake. Thus, without upgrading the vehicle's hardware, the mobile terminal's global positioning system enables vehicles without automatic parking to automatically park, eliminating the need for the driver to keep their foot on the brake for extended periods, improving driving comfort and enhancing the user experience.

[0047] In some embodiments of this disclosure, the positioning information includes latitude and longitude coordinates and timestamp information.

[0048] Specifically, the location in the positioning information can be represented by latitude and longitude coordinates, and each latitude and longitude coordinate corresponds to a timestamp. The positioning information obtained by the automatic parking device through GPS is the latitude and longitude coordinates of the vehicle at each time.

[0049] In other embodiments of this disclosure, the automatic parking device can determine, based on the acceleration and a pre-trained analysis model, whether the vehicle speed change within a preset time before the vehicle comes to a stop meets the conditions for engaging the parking brake. The pre-trained analysis model is trained based on pre-collected sample data, which includes acceleration sample data of the vehicle within a preset time and label information indicating whether the parking brake is engaged after the preset time. The acceleration sample data and the label information are in one-to-one correspondence.

[0050] Specifically, the pre-trained analysis model can be a classification model trained based on convolutional neural networks, deep neural networks, recurrent neural networks, etc. It can output classification results based on the input acceleration information, indicating whether the parking brake activation conditions are met or not. During the training of the analysis model, labeled sample data can be collected in advance, namely, acceleration sample data of each vehicle within a preset time and corresponding label information indicating whether the parking brake is activated after the preset time. This sample data can be collected and organized from the automatic parking log files of vehicles equipped with automatic parking functions, or it can be manually labeled based on unlabeled acceleration sample data; no limitation is made here. After the analysis model is trained, the automatic parking device can input the obtained vehicle acceleration into the analysis model to obtain the model's output results. Based on the output results, it can then determine whether the vehicle speed change within the preset time before the vehicle reaches a stationary state meets the parking brake activation conditions.

[0051] Optionally, the automatic parking device can collect vehicle acceleration data during vehicle operation and select acceleration data collected within a preset time before the parking brake is engaged, using this data to improve the training of the analysis model.

[0052] Figure 2 This is a flowchart illustrating a method for determining the conditions for opening the parking brake, as provided in an embodiment of this disclosure. Figure 2 As shown, based on the above embodiments, the conditions for opening the parking brake can be determined by the following method.

[0053] S201. Based on the acceleration, calculate the change in vehicle speed within a preset time before the vehicle comes to a standstill.

[0054] In this embodiment of the present disclosure, the automatic parking device can calculate the overall change in vehicle speed over a preset time period before the vehicle comes to a stop after obtaining the vehicle's acceleration.

[0055] In one exemplary embodiment of this disclosure, the automatic parking device can calculate the sum of the vehicle's accelerations at each unit of time within a preset time period before the vehicle comes to a standstill, thereby obtaining the change in vehicle speed within the preset time period.

[0056] In another exemplary embodiment of the present disclosure, the automatic parking device can, after obtaining the acceleration of the vehicle, calculate the speed of the vehicle at a first moment based on the acceleration data within a preset time before the vehicle comes to a stop, and determine its value as the change in vehicle speed within a preset time before the vehicle comes to a stop. The first moment is the moment when there is still a preset time before the vehicle comes to a stop.

[0057] S202. Determine that the change in vehicle speed is greater than or equal to a preset threshold.

[0058] In this embodiment of the present disclosure, the automatic parking device can calculate the change in vehicle speed and then compare the change in vehicle speed with a preset threshold to determine that the change in vehicle speed is greater than or equal to the preset threshold.

[0059] S203. Determine that the vehicle speed change within a preset time before the vehicle comes to a standstill meets the conditions for activating the parking brake.

[0060] In this embodiment of the present disclosure, the automatic parking device can determine the vehicle speed change within a preset time before the vehicle is stationary after determining that the change in vehicle speed is greater than or equal to a preset threshold, thereby satisfying the conditions for activating the parking brake.

[0061] This embodiment of the disclosure calculates the change in vehicle speed within a preset time before the vehicle comes to a standstill based on the acceleration, determines that the change in vehicle speed is greater than or equal to a preset threshold, and determines that the change in vehicle speed within the preset time before the vehicle comes to a standstill meets the conditions for opening the parking brake. It can calculate an accurate change in vehicle speed based on acceleration, and more accurately measure whether the vehicle meets the conditions for opening the parking brake, reducing the probability of misjudgment.

[0062] Figure 3 This is a flowchart illustrating a method for determining the pedal depth to reach a preset depth, as provided in an embodiment of this disclosure. Figure 3 As shown, based on the above embodiments, the pedal depth can be determined to reach the preset depth by the following method.

[0063] S301, Receive the braking signal and power system stop working information sent by the vehicle.

[0064] The brake signal in this embodiment can be understood as the signal generated when the brake pedal is pressed. When the user presses the automatic pedal, the vehicle's power system will also stop working.

[0065] In this embodiment of the disclosure, the automatic parking device can receive braking signals and information indicating that the power system has stopped working from the vehicle before determining that the vehicle is stationary based on positioning information.

[0066] S302. Based on the brake signal, determine the depth to which the brake pedal of the vehicle is depressed.

[0067] In this embodiment of the disclosure, the pedal depth can be understood as information obtained by a stroke sensor to characterize the depth to which the brake pedal is depressed.

[0068] In this embodiment of the disclosure, the automatic parking device can analyze the brake signal to determine the information contained therein about the depth to which the vehicle's brake pedal is depressed.

[0069] S303. Determine that the depth to which the brake pedal is depressed is greater than or equal to a preset depth.

[0070] In this embodiment of the present disclosure, the automatic parking device can, after obtaining the pedal depth where the brake pedal is depressed, compare the pedal depth with a preset depth to determine that the pedal depth is greater than or equal to the preset depth.

[0071] In one exemplary embodiment of the present disclosure, the automatic parking device can determine that the driver has pressed the brake pedal deeply after determining that the pedal depth is greater than or equal to a preset depth. At this time, it is determined that the user may want to activate the parking brake. Therefore, based on the positioning information and acceleration, it is further determined that the vehicle is stationary and the current condition of the vehicle meets the conditions for activating the parking brake.

[0072] This embodiment of the disclosure receives a brake signal and information indicating that the power system has stopped working from the vehicle. Based on the brake signal, it determines the depth to which the brake pedal is depressed and determines that the depth is greater than or equal to a preset depth. After determining that the user has deeply depressed the brake based on the received brake signal, it further analyzes whether the conditions for opening the parking brake are met based on positioning information and acceleration. This eliminates the need for the automatic parking device to continuously analyze positioning information and acceleration, reducing the overall workload while ensuring the parking brake function is achieved, and also reducing the probability of misinterpreting the user's intentions.

[0073] In some embodiments of this disclosure, the automatic parking device can determine, based on the positioning information and pre-acquired map data, that there are traffic lights within a preset range around the vehicle.

[0074] Specifically, the preset range can be understood as a circular area defined by the vehicle as the center and a preset length as the radius. The automatic parking device can determine the location of each traffic light based on pre-acquired map data, and then determine the preset range based on the vehicle's positioning information and the preset radius. By comparing the preset range with the location of each traffic light, it can determine that there are traffic lights within the preset range around the vehicle, and that the user may have stopped after encountering a red light. Therefore, the vehicle will not move forward in a short period of time, and it can be determined that the user may want to activate the parking brake. At this point, the vehicle speed change is further determined based on acceleration to meet the conditions for activating the parking brake. This allows the automatic parking device to reduce the overall workload while ensuring the parking brake function is achieved, and also reduces the probability of misjudging the user's intention.

[0075] Figure 4This is a flowchart illustrating a method for releasing the parking brake according to an embodiment of this disclosure. Figure 4 As shown, based on the above embodiments, the parking brake can be released by the following method.

[0076] S401, Receive information from the vehicle that the accelerator pedal has been pressed.

[0077] In this embodiment of the present disclosure, the automatic parking device can receive information from the vehicle that the accelerator pedal has been pressed after sending a control signal to the vehicle.

[0078] S402. Determine that the vehicle has released the parking brake, and execute the step of the mobile terminal obtaining the vehicle's location information and acceleration through the global positioning system.

[0079] In this embodiment of the present disclosure, after receiving information from the vehicle that the accelerator pedal has been pressed, the automatic parking device can determine that the user wants to control the vehicle to move forward. The user releases the vehicle's parking brake by pressing the accelerator pedal. Therefore, after receiving information that the accelerator pedal has been pressed, the automatic parking device can determine that the vehicle has released the parking brake and continue to execute the step in S104 where the mobile terminal obtains the location information and acceleration of the vehicle through the global positioning system.

[0080] This embodiment of the disclosure determines that the vehicle has released the parking brake by receiving information from the vehicle that the accelerator pedal has been pressed, and executes the steps of the mobile terminal obtaining the vehicle's location information and acceleration through the global positioning system. This enables the vehicle's position and acceleration to continue monitoring after the parking brake is released, so that the parking brake can be activated again when needed.
