Description

Technical Field

[0001] The present invention relates to the field of automatic parking control, and in particular to an automatic parking control method and system with multi-mode selection. Background Art

[0002] Autohold is a vehicle auxiliary function. When the autohold function is turned on, the parking brake system will automatically start after the vehicle stops after braking. At this time, the electronic brake system such as EPS will intervene to automatically brake. At this time, the brake pedal will feel a sense of unloading, and the driver can release the brake pedal without the vehicle slipping, thereby improving the user experience. When you need to drive, you only need to step on the accelerator pedal to resume the vehicle's driving.

[0003] The existing automatic parking technology is generally only provided with an on and off switch, and the automatic parking system starts and shuts down the automatic parking function according to the on and off switch. With the advancement of technology, a solution for automatically turning on and off the automatic parking system according to user needs has been developed, and the automatic parking function can be adaptively turned on and off through voice, monitoring of vehicle status, etc.

[0004] However, existing technologies often only consider how to turn on and off the automatic parking function, and there is no relevant technology research and development on how to match different users after the parking function is activated. Generally, the automatic parking function of the car is fixed before leaving the factory, and the automatic parking brake release logic and time are fixed under various working conditions or different user usage. It cannot meet the needs of different customers, and they often complain that the automatic parking release is slow or too fast, resulting in rear-end collisions. It cannot meet the driving habits of all customers at the same time, and cannot provide selectivity, resulting in poor user experience. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a multi-mode selection automatic parking control method for realizing a variety of automatic parking system modes for users to choose and use, so as to achieve the purpose of matching the automatic parking release time with user needs through different modes.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a multi-mode selection automatic parking control method, the automatic parking system obtains the release parameters selected or set by the user through the vehicle-mounted interactive system, and when the release of the automatic parking function is triggered, the release of the automatic parking function is controlled based on the release parameters.

[0007] The release parameters selected or set by the user include the response time of the auto hold function release.

[0008] Automatic parking modes corresponding to a variety of release parameters are pre-set, and the parking function of the vehicle is released by selecting the automatic parking mode.

[0009] When the automatic parking system controls the vehicle to be in a parking state, the driving torque of the wheel end is detected in real time. When the driving torque of the wheel end is greater than the starting torque of the vehicle, the vehicle braking circuit is controlled to start depressurizing and the automatic parking function is controlled to release the parking after N milliseconds. The vehicle moves under the action of the driving torque; various automatic parking models correspond to different N values.

[0010] The current automatic parking mode is recorded each time the vehicle is turned off. After the vehicle is started and the conditions for starting the automatic parking function are met, the automatic parking system executes the automatic parking mode recorded before the last shutdown to control the parking release of the vehicle.

[0011] The automatic parking control system obtains the vehicle driving mode data. The automatic parking mode is associated with the vehicle driving mode. The corresponding automatic parking mode is obtained and executed according to the current vehicle driving mode.

[0012] The vehicle driving modes include ECO mode, NORMAL mode and SPORT mode. When the vehicle is started, the vehicle driving mode is read. When the vehicle driving mode is in NORMAL mode, the automatic parking mode recorded when the power was last turned off is used for automatic parking control, or the automatic parking mode corresponding to the current vehicle driving mode is used for parking control; when the vehicle driving mode is in ECO mode or SPORT mode, the automatic parking mode corresponding to the current vehicle driving mode is used for parking control; the parking mode manually selected by the user is set to the highest priority. When the parking mode manually selected and entered by the user is detected after this power-on, the automatic parking mode manually selected by the user is executed.

[0013] The automatic parking mode includes at least an automatic parking NORMAL mode and an automatic parking SPORT mode, wherein the N value in the automatic parking NORMAL mode is greater than the N value in the automatic parking SPORT mode, wherein the N value is the time value required for the automatic parking function to be released.

[0014] The automatic parking mode also includes a custom mode, which is used to input the configuration parameter N value set by the user through the in-vehicle interactive system. In the custom mode, the automatic parking system controls the parking based on the parameter N value input by the user; the N value is limited to a set value range by software.

[0015] A multi-mode selection automatic parking control system, the control system comprising an automatic parking system and an in-vehicle interactive system; a user inputs release parameters selected or set by the user into the automatic parking system through the in-vehicle interactive system, and the automatic parking system controls the release of the automatic parking function based on the release parameters when the release of the automatic parking function is triggered according to the parameters input by the user or the automatic parking mode selected.

[0016] The advantages of the present invention are: it is used to realize multiple automatic parking system modes for users to choose and use, and the purpose of matching the automatic parking release time with user needs is achieved through different modes. The automatic parking function has different release times and different driving experiences in different modes. At the same time, the two control modes of the automatic parking system can be set separately or in association with the vehicle mode to improve the driving experience of the whole vehicle. The driving habits of different customers can be met by different parking release times, and the automatic parking control mode is associated with the vehicle control mode to achieve the style selection of the vehicle driving mode.

[0020] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0021] The automatic parking control system mentioned in the present invention is used to realize the automatic parking function that users can selectively realize in multiple modes, so as to meet the different needs of users, and two modes are used as examples for introduction. The two automatic parking modes are NORMAL mode and SPORT mode. The different parking release times are used to meet the driving habits of different customers. At the same time, the automatic parking control mode is associated with the vehicle control mode to realize the style selection of the vehicle driving mode. The specific introduction is as follows:

[0022] The present embodiment provides a multi-mode selection automatic parking control method, including the automatic parking system obtaining the release parameters selected or set by the user through the vehicle-mounted interactive system, and when the release of the automatic parking function is triggered, the release of the automatic parking function is controlled based on the release parameters. The vehicle-mounted interactive system includes but is not limited to the vehicle's multimedia touch screen, the vehicle's mechanical physical buttons, and virtual buttons and soft switches set in the vehicle-mounted touch screen, which are used to enter the user's setting parameters or the user's selection switching commands, which are used to connect to the automatic parking system, and the automatic parking system executes the automatic parking control function according to the release parameters input by the user or the mode selected by the user. After the automatic parking system is started, it will execute and control the automatic parking function according to the release parameters input by the user or the selected mode to achieve the purpose of automatic parking. The activation of the automatic parking system function requires a judgment on the vehicle's conditions. The automatic parking function will only be activated when the conditions are met, otherwise it will not be activated. After the automatic parking system function is activated, the status of the brake pedal and the vehicle speed are collected to determine whether the parking function is activated. If activated, the automatic parking system controls the electronic braking system to brake and clamp the vehicle. Then the vehicle's accelerator pedal is collected in real time to obtain the vehicle's driving torque. When the vehicle's driving torque is greater than the set threshold, the automatic parking function needs to be released. At this time, the automatic parking system controls the release of the vehicle's parking function according to the release parameters set by the user or the release parameters selected by the user in the automatic parking mode.

[0023] The release parameter here is the response time of the automatic parking function release, which refers to the response time required for the automatic parking system to fully release the parking function from the beginning, that is, the action time N milliseconds from the beginning of the pressure relief to the end of the pressure relief of the automatic parking system controlling the brake circuit.

[0024] There are two aspects to the user's setting or selection of the automatic parking system through the vehicle interactive system:

[0025] 1. Develop multiple automatic parking modes with different release parameters N in advance. The automatic parking function corresponding to each mode differs only in the release time N value when releasing the parking. The release time is N milliseconds, and the release is controlled at the millisecond level. Pre-set multiple automatic parking modes corresponding to release parameters, each automatic parking mode corresponds to a different N value, and the parking function of the vehicle is released by selecting the automatic parking mode. The selectable automatic parking modes are displayed on the display screen of the in-vehicle interactive system. The user sets the working mode of the automatic parking system by selecting the automatic parking mode, thereby controlling the parking release.

[0026] 2. The user manually enters the release parameter, that is, the release time N value. If the user manually enters the N value instead of selecting an existing mode, it is defined as a custom mode. In the custom mode, the user enters the value of the release parameter N value through the vehicle teaching system, and the value range of the N value is limited in advance by software, allowing only the N value entered by the user to be adjusted within the limited range, thereby satisfying the user's purpose of adaptive adjustment.

[0027] When the automatic parking system controls the vehicle to be in a parking state, the driving torque of the wheel end is detected in real time. When the driving torque of the wheel end is greater than the starting torque of the vehicle, the vehicle braking circuit is controlled to start depressurizing and the automatic parking function is controlled to release the parking state after N milliseconds, and the vehicle travels under the action of the driving torque; wherein the N value is different in different automatic parking modes or release parameters, and different control effects of starting can be achieved through different N values, thereby meeting the different needs of users. For example, some people like to release the parking slowly, while some people like to release the parking quickly. Therefore, different personalized needs of users can be met by selecting different modes or manually entering parameters.

[0028] In a preferred embodiment, a memory function of the automatic parking mode is provided, and the current automatic parking mode is recorded each time the vehicle is shut down. When the vehicle is started and the conditions for starting the automatic parking function are met, the automatic parking system executes the automatic parking mode recorded before the last shutdown to control the parking release of the vehicle, thereby realizing the recording of user preferences, and controlling the execution of the automatic parking function according to the recorded automatic parking mode after the vehicle is started next time.

[0029] In a preferred embodiment, since the driving mode of the vehicle generally represents the driving habits and needs of the user, the vehicle driving mode and the automatic parking mode can be matched, so as to automatically adjust the parameters of the automatic parking function to match the needs of the user and improve the user experience. The vehicle driving mode generally includes ECO mode, NORMAL mode and SPORT mode, each mode corresponds to the different driving habits of the user, such as eco mode represents energy-saving mode, in this mode, it is used to pay more attention to fuel consumption, and in sport mode, it is used to demand more power, so the vehicle driving mode and the automatic parking mode can be corresponded and matched according to this situation. After the vehicle starts working, the automatic parking control system obtains the whole vehicle driving mode data, the automatic parking mode is associated with the whole vehicle driving mode, and the corresponding automatic parking mode is obtained according to the current vehicle driving mode. The corresponding relationship between the automatic parking mode and the whole vehicle driving mode is pre-calibrated and stored in the controller memory of the automatic parking system. When needed, the data is called to obtain the corresponding automatic parking mode, thereby achieving the purpose of quickly and automatically controlling the automatic parking according to the vehicle driving mode.

[0030] In a preferred embodiment of the present application, when the vehicle is started, the vehicle driving mode is read. When the vehicle driving mode is in NORMAL mode, the automatic parking mode set or selected by the user through the vehicle-mounted interactive system recorded when the power was last turned off is used for automatic parking control; if the automatic parking mode at the last power off is not recorded, the automatic parking mode corresponding to the current vehicle driving mode is used for parking control; the purpose of this is to meet the automatic parking mode manually set by the user in NORMAL mode as much as possible, because the mode manually set or selected by the user is the mode closest to the user's needs, and if there is no record or the recorded automatic driving mode is not manually selected by the user, the automatic parking mode corresponding to the pre-set NORMAL mode is directly used for parking control. This method meets the needs of manual selection by the user and achieves the purpose of improving user experience, while also meeting the automatic selection and execution of the working mode of the automatic parking system.

[0031] When the vehicle driving mode is in ECO mode or SPORT mode, the automatic parking mode corresponding to the current vehicle driving mode is used for parking control. Because the user adjusts the vehicle driving mode, it actually means that the user's posture needs have changed at this time. The pre-set comparison relationship between the driving mode and the automatic parking mode takes into account the relationship between the vehicle driving mode and the automatic parking mode during calibration. Therefore, according to this comparison relationship, the automatic parking mode required by the driver at this time can be most accurately matched automatically. For example, the sport mode pursues sportiness, and the corresponding N value of the automatic parking mode will be as small as possible. In this way, the release time of the automatic parking function is reduced, and the sportiness is increased, thereby meeting the needs of users.

[0032] In a preferred embodiment, the priority of the parking mode manually selected by the user is set to be the highest. No matter what automatic parking mode the automatic parking system is in at this time, once the user selects the automatic parking mode or enters the release parameters through the vehicle-mounted interactive system, the function of the automatic parking system is configured with the parameters manually selected or set by the user, thereby realizing the automatic parking function. When the parking mode manually selected and entered by the user is detected after the power-on, the automatic parking mode manually selected by the user is executed. The purpose of this is to meet the needs of users as much as possible, with the highest priority for manual control by the user and the second priority for automatic selection of the parking mode according to the vehicle driving mode, thereby meeting the needs of users and improving user experience.

[0033] The automatic parking mode in this embodiment includes at least an automatic parking NORMAL mode and an automatic parking SPORT mode, wherein the N value in the automatic parking NORMAL mode is greater than the N value in the automatic parking SPORT mode, wherein the N value is the time required for the automatic parking function to be released. The smaller the N value, the faster the release, thereby reducing the sportiness and satisfying the requirements of the sport mode. The corresponding relationship between the driving mode and the automatic parking mode is as follows: Figure 2 As shown, the automatic parking NORMAL mode corresponds to the ECO and NORMAL modes of the vehicle driving mode; the automatic parking SPORT mode corresponds to the SPORT mode of the vehicle driving mode.

[0034] In a preferred solution of this embodiment, the automatic parking mode also includes a custom mode, which is used to input the configuration parameter N value set by the user through the vehicle interactive system. The automatic parking system performs parking control based on the parameter N value input by the user in the custom mode; wherein the N value is limited to a set value range by software. This can meet the user's adjustment of the release time of the automatic parking mode within a certain range, thereby providing the user with more adjustability and further improving the user experience.

[0035] This embodiment also provides a multi-mode selection automatic parking control system, the control system includes an automatic parking system and an in-vehicle interactive system; the user inputs the release parameters selected or set by the user to the automatic parking system through the in-vehicle interactive system, and the automatic parking system controls the release of the automatic parking function based on the release parameters when the release of the automatic parking function is triggered according to the parameters input by the user or the selected automatic parking mode. The automatic parking system also accesses the vehicle CAN network to obtain the vehicle's driving mode data and normal operating parameters. The automatic parking system controls the parking of the vehicle according to the control method in the above embodiment, and realizes different parking modes for vehicle parking control.

[0036] This embodiment uses two automatic parking modes for illustration, which are NORMAL mode and SPORT mode. Customers can make independent selections through the AUTOHOLD mode selection interface on the large in-vehicle screen according to their driving habits. The NORMAL mode is relatively safe. The driving torque obtained at the wheel end is greater than the starting torque of the vehicle, the brake circuit starts to release pressure, and the automatic parking function is released after N milliseconds, and the vehicle is no longer parked. The vehicle starts to travel under the action of the driving torque; the SPORT mode is characterized by a relatively fast response. The driving torque obtained at the wheel end is greater than the starting torque of the vehicle, the brake circuit starts to release pressure quickly, and the automatic parking function is released after N / 2 milliseconds, and the vehicle is no longer parked. The vehicle starts to travel under the action of the driving force; at the same time, the automatic parking control mode can also be associated with the whole vehicle driving mode. According to the default combination relationship, the mode changes with the selection of the whole vehicle driving mode;

[0037] The automatic parking control scheme of the parking mode selectable in this embodiment is based on the basic configuration of the vehicle, and is also equipped with an LCD display, an instrument, a vehicle dynamic control system (ESC or Onebox), and the vehicle dynamic control system contains a slope sensor, and is also equipped with an electronic parking system, an automatic parking function and a vehicle driving mode selection function. Based on the above conditions, the automatic parking control scheme in this embodiment can be realized.

[0038] like Figure 1 The figure shows the logic control diagram for the automatic parking control system mode selection. The automatic parking function is turned on when the following conditions are met:

[0039] 1. The engine needs to be in the starting state;

[0040] 2. The car door should be completely closed;

[0041] 3. The driver's seat belt needs to be fastened;

[0042] 4. The LCD screen in the car needs to be activated and work normally without any errors;

[0043] 5. When the above four conditions are met, the mode of the automatic parking system executes the automatic parking mode of the vehicle before the last shutdown. If you need to change the automatic parking mode, you can select the NORMAL mode or SPORT mode through the automatic parking system mode selection interface on the large screen. After selection, the central gateway will process and record it, and support the default mode selection after the next vehicle start; the NORMAL mode is relatively safe. The driving torque obtained at the wheel end is greater than the starting torque of the vehicle, the brake circuit begins to release pressure, and the automatic parking function is released after N milliseconds. The vehicle is no longer parked and starts to move under the action of the driving torque; the SPORT mode is characterized by a relatively fast response. The driving torque obtained at the wheel end is greater than the starting torque of the vehicle, the brake circuit begins to release pressure quickly, and the automatic parking function is released after N / 2 milliseconds. The vehicle is no longer parked and starts to move under the action of the driving force;

[0044] like Figure 2 The following figure shows the logical relationship between the automatic parking mode selection and the vehicle and system mode selection. The automatic parking mode is automatically matched according to the vehicle driving mode.

[0045] 1. The function of vehicle driving mode selection can be associated with the automatic parking mode. When the vehicle driving mode is selected in ECO and NORMAL modes, the automatic parking mode is NORMAL mode; when the vehicle driving mode is selected in SPORT mode, the automatic parking mode is SPORT mode;

[0046] 2. When the vehicle driving mode maintains the current state, the automatic parking mode can be selected as normal mode or sport mode through the automatic parking system mode selection interface on the large screen. After selection, the central processor will record it and support the default mode selection after the vehicle is started next time.

[0047] Through the above scheme, this embodiment realizes different release times of the automatic parking function in different modes and different driving experiences. At the same time, the two control modes of the automatic parking system can be set separately or in association with the vehicle mode to improve the driving experience of the whole vehicle. The driving habits of different customers can be met by different parking release times, and the automatic parking control mode is associated with the vehicle control mode to achieve the style selection of the vehicle driving mode.

[0048] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
