Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic parking control, in particular to a multi-mode selection automatic parking control method and system. BACKGROUND

[0002] Autohold is a vehicle auxiliary function. When the automatic parking function is turned on, the parking brake system will automatically start after each brake is stopped. At this time, the electronic brake system such as EPS will intervene to automatically brake, and at this time the brake pedal will feel a kind of unloading feeling, and the driver can release the brake pedal without slipping the vehicle, thereby improving the user experience. When driving is needed, the vehicle can be restored by stepping on the accelerator pedal.

[0003] The prior art automatic parking generally only has an on and off switch, and the automatic parking system starts and stops the automatic parking function according to the on and off switch. With the progress of technology, a scheme of automatically turning on and off the automatic parking system according to user needs is developed, and the automatic parking function is turned on and off adaptively through voice, monitoring the vehicle state and the like.

[0004] However, the prior art generally only considers how to turn on and off the automatic parking function, and does not have related research and development on how to match different users after the parking function is started. Generally, the automatic parking function of the automobile is fixed before leaving the factory, and the automatic parking brake release logic and time are fixed under various working conditions or different user use conditions. It cannot meet the needs of different customers, and customers often complain that the automatic parking release is slow or too fast, which leads to rear-end collision. It cannot meet the driving habits of all customers at the same time, cannot provide selectivity, and leads to poor user experience. SUMMARY

[0005] The purpose of the present application is to overcome the shortcomings of the prior art and provide a multi-mode selection automatic parking control method for realizing multiple automatic parking system modes for user selection and use, and realizing the purpose of matching user needs through different modes.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: 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 interaction system, and controls the release of the automatic parking function based on the release parameters when triggering the release of the automatic parking function.

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

[0008] A plurality of release parameters corresponding to the automatic parking mode are set in advance, and the release of the parking function of the vehicle is realized by selecting the automatic parking mode.

[0009] When the automatic parking system controls the vehicle in the parking state, it detects the driving torque of the wheel end in real time. When the driving torque of the wheel end is greater than the vehicle's starting torque, it controls the vehicle's braking circuit to start depressurizing and controls the automatic parking function to release the parking position after N milliseconds. The vehicle then 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 vehicle's parking release.

[0011] The automatic parking control system obtains the vehicle driving mode data. The automatic parking mode is associated with the vehicle driving mode and 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 is 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 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 includes 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 selected automatic parking mode.

[0016] The present invention offers the advantage of enabling multiple automatic parking system modes for user selection, allowing the automatic parking release time to be tailored to user needs. The automatic parking function provides different release times and driving experiences in different modes. Furthermore, the two control modes of the automatic parking system can be set independently or linked to the vehicle mode, enhancing the overall driving experience. By varying the parking release time, different driving habits can be accommodated. Linking the automatic parking control mode with the vehicle control mode allows for personalized driving style.

[0019] Figure 2 Schematic diagram of the automatic parking mode selection principle in the associated vehicle mode of the present invention. DETAILED DESCRIPTION

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

[0021] The automatic parking control system mentioned in this invention is used to realize the user's selective automatic parking function in multiple modes, thereby meeting the different needs of users. Two modes are used as examples for introduction. The two automatic parking modes are NORMAL mode and SPORT mode. The two automatic parking modes are different to meet the driving habits of different customers by different parking release times. At the same time, the automatic parking control mode is linked with the vehicle control mode to realize the style selection of the vehicle driving mode. The details are 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 controlling the release of the automatic parking function based on the release parameters when the release of the automatic parking function is triggered. 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, etc., 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. 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 mode selected by the user to achieve the purpose of automatic parking. The activation of the automatic parking system requires a judgment of 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 brake pedal status and vehicle speed status 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's brakes. 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, that is, the action time N milliseconds from the start of the automatic parking system controlling the brake circuit to release pressure to the end of pressure release.

[0024] There are two aspects to setting or selecting the automatic parking system through the vehicle interactive system:

[0025] 1. Pre-develop multiple automatic parking modes with different release parameters N. The corresponding automatic parking function of each mode differs only in the release time N value when releasing the parking function. The release time is N milliseconds, and the release is controlled in milliseconds. Multiple automatic parking modes corresponding to pre-set release parameters are configured, each corresponding to a different N value. The vehicle's parking function is released by selecting the automatic parking mode. The selectable automatic parking modes are displayed on the display of the in-vehicle interactive system. The user sets the operating 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, namely the release time N. If the user manually enters the N value instead of selecting an existing mode, it is defined as custom mode. In custom mode, the user enters the release parameter N value through the onboard teaching system. The range of N value is pre-limited by software, allowing the user to adjust the N value only within the restricted range, thereby meeting the user's adaptive adjustment purpose.

[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 position after N milliseconds, and the vehicle travels under the action of the driving torque; the N value is different in different automatic parking modes or release parameters. Different N values ​​can be used to achieve different control effects for starting, thereby meeting different needs of users. For example, some people like slow release of parking, while some people like fast release of parking. 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 turned off. 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. After the vehicle is started next time, the execution of the automatic parking function is controlled according to the recorded automatic parking mode.

[0029] In a preferred embodiment, since a vehicle's driving mode generally represents a user's driving habits and needs, the vehicle's driving mode can be matched to an automatic parking mode, thereby automatically adjusting the parameters of the automatic parking function to suit the user's needs and improving the user experience. Vehicle driving modes generally include ECO mode, NORMAL mode, and SPORT mode, each corresponding to a different user's driving habits. For example, eco mode represents an energy-saving mode for those who prioritize fuel efficiency, while sport mode is for those who prioritize power. Therefore, the vehicle's driving mode and automatic parking mode can be matched accordingly. After the vehicle is started, the automatic parking control system acquires vehicle driving mode data. The automatic parking mode is associated with the vehicle's driving mode and the corresponding automatic parking mode is retrieved and executed based on the current vehicle driving mode. The correspondence between the automatic parking mode and the vehicle driving mode is pre-calibrated and stored in the automatic parking system's controller memory. When needed, the data is retrieved and compared to obtain the corresponding automatic parking mode, thereby achieving rapid and automatic control of automatic parking based on the vehicle's 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 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 improves the 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 at this time have changed. The pre-set mapping 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 mapping 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, so that 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 user-selected parking mode is given the highest priority. Regardless of the current automatic parking mode, once the user selects the automatic parking mode or enters the release parameters through the vehicle interaction system, the automatic parking system is configured with the user-selected or set parameters, thereby implementing the automatic parking function. Upon detecting the user-selected parking mode after power-up, the user-selected automatic parking mode is executed. This is intended to meet user needs as much as possible, giving the user's manual control the highest priority and the automatic parking mode selected based on the vehicle's driving mode the second highest priority, thereby meeting user needs and improving the user experience.

[0033] The automatic parking mode in this embodiment includes at least the automatic parking NORMAL mode and the 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, thus reducing the sportiness and meeting the requirements of the sport mode. 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 embodiment of this embodiment, the automatic parking mode also includes a custom mode, in which a user-configured parameter N value is input through the vehicle's interactive system. In this custom mode, the automatic parking system controls parking based on the user-entered parameter N value. The N value is software-limited to a set range. This allows users to adjust the release time of the automatic parking mode within a certain range, providing greater adjustability and further enhancing the user experience.

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

[0036] This embodiment uses two automatic parking modes for illustration, namely NORMAL mode and SPORT mode. Customers can make their own selection based on their driving habits through the AUTOHOLD mode selection interface on the in-vehicle large screen. NORMAL mode is relatively safe. When the driving torque obtained at the wheel end is greater than the vehicle's starting torque, the brake circuit begins to release pressure, and the automatic hold function is released after N milliseconds, and the vehicle is no longer parked, and begins to move under the action of the driving torque. SPORT mode is characterized by a relatively fast response. When the driving torque obtained at the wheel end is greater than the vehicle's starting torque, the brake circuit begins to release pressure quickly, and the automatic hold function is released after N / 2 milliseconds, and the vehicle is no longer parked, and begins to move under the action of the driving force. At the same time, the automatic parking control mode can also be associated with the entire vehicle driving mode. According to the default combination relationship, the mode changes with the selection of the entire vehicle driving mode.

[0037] The automatic parking control scheme of this embodiment, with selectable parking modes, is based on the vehicle's basic configuration, along with an LCD display, instrument cluster, and vehicle dynamics control (ESC or Onebox). The vehicle dynamics control system also includes a slope sensor, an electronic parking system, automatic parking functionality, and a vehicle driving mode selection function. Based on these conditions, the automatic parking control scheme of this embodiment can be implemented.

[0038] like Figure 1 The figure below shows the logic control diagram for the automatic parking control system mode selection. The automatic parking function is activated 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 working properly without any errors;

[0043] 5. When the above four conditions are met, the automatic parking system will execute the automatic parking mode that the vehicle was in before the engine was last turned off. If you need to change the automatic parking mode, you can select 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. The automatic parking function is released after N milliseconds, and the vehicle is no longer parked. The vehicle 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. The automatic parking function is released after N / 2 milliseconds, and the vehicle is no longer parked. The vehicle 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 vehicle driving mode selection function can be linked to the automatic parking mode. When the vehicle driving mode is selected in ECO and NORMAL mode, 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's driving mode remains in its 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 solution, this embodiment achieves different release times for the automatic parking function in different modes, resulting in a different driving experience. Furthermore, the two control modes of the automatic parking system can be set independently or linked to the vehicle mode, enhancing the overall driving experience. By varying the parking release time, different driving habits can be met. Linking the automatic parking control mode with the vehicle control mode allows for personalized driving style selection.

[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 scope of protection of the present invention.
