[0051] The handle control method of the vehicle of the embodiment of the present application adopts the handle control system of the vehicle. Before introducing the handle control method of the vehicle of the embodiment of the present application, the handle control system of the vehicle of the embodiment of the present application is introduced first.

[0052] It can be understood that the embodiment of the present application aims to provide an intelligent rail handle device for the second row of a vehicle to improve the convenience and safety of passengers in the second row getting on and off the vehicle, especially for people with lower height such as children and the elderly.

[0053] Specifically, the handle control system of the vehicle includes a rail, a sliding block, a handle, an image acquisition unit, a signal transmission unit, an image processing unit, a control unit, a driving unit, and a feedback unit. The image acquisition unit of the embodiment of the present application is a high-definition camera, which is used to capture the full-body image of the passenger and has high resolution and good distortion correction capability. The embodiment of the present application adjusts the pixels and focal length of the high-definition camera to ensure the resolution and recognition accuracy of the image. The signal transmission unit of the embodiment of the present application is a wireless or wired communication device, such as a router, a switch, etc. The signal transmission unit has stable signal transmission capability and transmits the collected image signals to the control unit in real time and losslessly. The image processing unit of the embodiment of the present application is a computer or a special image processing hardware device, such as an image processor or a graphics card, etc. The image processing unit has high-efficiency image processing capability and can quickly and accurately extract the height data of the passenger.

[0054] The control unit of the embodiment of the present application is a microcontroller or a processor, and corresponding control software and algorithms. The control unit has intelligent decision-making capability and can automatically adjust the height of the handle according to the height data of the passenger. The driving unit of the embodiment of the present application is a driving device such as a motor or an actuator, and corresponding driving circuit and control circuit. The driving unit can adjust the height of the handle according to the instructions of the control system and has the ability of precise control and rapid response. The feedback unit of the embodiment of the present application is a feedback device such as a position sensor or a height sensor, and corresponding signal processing circuit. The feedback unit monitors the position and height of the handle in real time and feeds back the data to the control system, and has the ability of high precision and real-time response.

[0055] Further, the handle control system of the vehicle of the embodiment of the present application further includes a safety guarantee unit, which is a guarantee device such as an emergency stop button or other safety protection device, which can ensure the safety of the adjustment process, including safety protection measures and emergency stop mechanism, and has reliability and stability.

[0056] Optionally, Figure 1 The schematic diagram of the handle control system of the vehicle of one specific embodiment of the present application is as shown in FIG. 1. Figure 1As shown, the track of the handle control system of the vehicle of the embodiment of the present application is installed on the upper end of the B pillar of the automobile, the sliding block can slide on the track, and the handle body is connected with the sliding block and can move along the track with the sliding block. Through the cooperative work of the above-mentioned system units, the handle control system of the vehicle can automatically adapt to passengers of different heights, provide convenient boarding gripping points, and is more friendly and safe for children and old passengers, thereby improving the comfort and safety of the vehicle, especially for the second-row passengers in large vehicles.

[0057] Next, the handle control method of the vehicle of the present application will be introduced in combination with specific embodiments.

[0058] Specifically, Figure 2 The flowchart of the handle control method of the vehicle provided by the embodiment of the present application is shown.

[0059] As Figure 2 shown, the handle control method of the vehicle includes the following steps:

[0060] In step S201, the current position of the handle is obtained by the feedback unit, the full-body image information of the passenger is collected by the image collection unit, and the contour information of the passenger is obtained by processing the full-body image information by the image processing unit. The height data of the passenger is obtained by analyzing the contour information based on a preset image processing algorithm.

[0061] Among them, the current position of the handle of the embodiment of the present application is obtained by the feedback unit, that is, the position and height of the handle are obtained in real time by a position sensor or a height sensor and the like, and are transmitted to the control unit by a signal transmission unit.

[0062] In the embodiment of the present application, the high-definition camera is used to collect the full-body image information of the passenger, which includes head information, upper body information and lower body information, so as to obtain the height of the passenger by analyzing the body proportion.

[0063] Further, the full-body image information collected by the embodiment of the present application is processed to extract the contour information of the passenger, and the image processing algorithm such as edge detection and image segmentation is used to analyze the image to obtain the height data of the passenger.

[0064] It should be noted that the camera with high resolution can be selected in the embodiment of the present application, so as to capture more delicate image details. High-resolution images are helpful to more accurately identify the contour and height of the passenger. In addition, the appropriate focal length and angle of view can be selected according to the space layout and passenger position inside the vehicle, so as to ensure that the camera can clearly shoot the full-body image of the second-row passenger, while avoiding image distortion.

[0065] Therefore, by selecting a high-definition camera, reasonably installing a position, real-time image capturing and transmission, and accurate image processing and height recognition algorithm, the image acquisition module can accurately capture the full-body image of the second row of passengers, and provide reliable data support for subsequent handrail height adjustment.

[0066] In step S202, the target position of the handrail is obtained based on the preset height adjustment strategy and the height data by the control unit, and a target control instruction is generated according to the target position.

[0067] It can be understood that the control unit of the embodiment of the application can automatically adjust the height of the handrail according to the height data of the passenger, that is, the target position of the handrail is obtained according to the height data, so that the target control instruction is generated according to the target position, and the target control instruction is executed by the driving unit.

[0068] Specifically, the preset height adjustment strategy of the embodiment of the application matches the passenger height data with the handrail height to achieve personalized and comfortable riding experience. The preset height adjustment strategy of the embodiment of the application can be a series of algorithms or rules, which aims to optimize the position of the handrail according to the specific height of the passenger.

[0069] Optionally, the embodiment of the application can establish a linear relationship between the passenger height and the handrail height, for example, a reference height and a corresponding reference handrail height can be set, and then the handrail height is adjusted by a certain proportion according to the difference between the passenger height and the reference height.

[0070] Optionally, the embodiment of the application can use a piecewise function algorithm to divide the passenger height into multiple intervals, and each interval corresponds to a specific handrail height adjustment rule. For example, for shorter passengers, the handrail may need to be adjusted lower; and for taller passengers, the handrail needs to be adjusted higher. By applying different adjustment rules in different height intervals, the comfort needs of passengers can be more carefully met.

[0071] Optionally, the embodiment of the application can use big data and machine learning technology to develop a height adjustment strategy based on statistical learning. By collecting a large amount of passenger height data and their preference information for the height of the handrail, a machine learning algorithm is used for training and optimization to establish a complex mapping relationship between the passenger height and the handrail height. Thus, the demand of the passenger for the height of the handrail can be more accurately predicted, and personalized adjustment can be automatically performed.

[0072] In addition, when formulating the height adjustment strategy, the embodiment of the application can also refer to the relevant principles of ergonomics. By considering the physiological characteristics and comfort needs of passengers, a more reasonable and scientific height adjustment strategy can be designed. For example, the height range of the handrail is determined according to the natural stretching range of the human arm.

[0073] It should be noted that, regardless of which algorithm or rule is used, the goal of the preset height adjustment strategy is to enable the handle to be automatically and accurately adjusted to the most comfortable height position for the passenger.

[0074] Further, the target control instruction of the embodiment of the present application includes specific height information to which the handle needs to be adjusted, and after the control instruction from the processor is received by the driving unit, the instruction content is parsed, and the corresponding actuator (such as a motor) is controlled to act.

[0075] Therefore, the present application can automatically adjust the height of the handle according to the passenger height data, and provide a more comfortable and convenient riding experience for the passenger.

[0076] In step S203, the current position of the handle is adjusted to the target position according to the target control instruction by the driving unit.

[0077] Specifically, the driving unit of the embodiment of the present application drives the handle to move up and down according to the requirements of the target control instruction until the specified height position is reached.

[0078] After the adjustment is completed, the passenger can also adjust the height of the handle as needed.

[0079] Optionally, in some embodiments, when the current position of the handle is adjusted to the target position according to the target control instruction, it further includes: obtaining the current position and calculating the deviation between the current position and the target position; determining whether the handle meets the preset fine adjustment condition according to the deviation; if the handle meets the preset fine adjustment condition, generating a current fine adjustment instruction based on the deviation, and adjusting the current position according to the current fine adjustment instruction.

[0080] It can be understood that the embodiment of the present application obtains the current position of the handle in real time by installing a position sensor or a height sensor, and feeds it back to the control unit. During the adjustment process, if the sensor detects that the position of the handle does not meet the requirements of the instruction, the control system can make corresponding adjustments to ensure that the handle can accurately stay at the specified height.

[0081] Specifically, the embodiment of the present application first calculates the deviation between the current position and the target position, and the preset fine adjustment condition of the embodiment of the present application includes the size of the deviation, the change rate of the deviation, the moving speed of the handle and other factors. If the deviation is small and meets certain stability requirements, it can be considered that the handle has approached the target position and needs to be fine-tuned to ensure accurate arrival.

[0082] Further, if the handle meets the fine-tuning condition, the system generates a fine-tuning instruction based on the current deviation, which specifies how the handle needs to further adjust its position to reduce or eliminate the deviation. In addition, the fine-tuning instruction of the embodiments of the present application can include information such as the direction, speed, and acceleration of the adjustment.

[0083] Thus, by introducing the fine-tuning mechanism, the embodiments of the present application can significantly improve the accuracy and stability of the handle control system of the vehicle, ensuring that the handle reaches the target position quickly and smoothly, thereby improving user experience and product performance.

[0084] Optionally, in some embodiments, after adjusting the current position according to the current fine-tuning instruction, the steps of repeatedly executing the steps of obtaining the current position, calculating the deviation between the current position and the target position, and determining whether the handle meets the preset fine-tuning condition according to the deviation are further included; if the handle meets the preset fine-tuning condition, the current fine-tuning instruction is updated based on the deviation, and the current position is adjusted according to the current fine-tuning instruction until the current position meets the preset accuracy requirement.

[0085] Specifically, after adjusting the current position of the handle according to the current fine-tuning instruction for the first time, the system does not stop immediately, but continues to perform the fine-tuning process, including obtaining the current position of the handle again, and calculating the deviation between this position and the target position. The system will again determine whether the handle still meets the preset fine-tuning condition according to the new deviation, which can include the size of the deviation, whether the deviation is within an acceptable range, the trend of the deviation, etc.

[0086] Optionally, if the handle still meets the fine-tuning condition, it means that further adjustment is needed to reduce the deviation. At this time, the system updates the fine-tuning instruction according to the current deviation. This new fine-tuning instruction can adjust parameters such as the direction, speed, or acceleration of the adjustment to more accurately guide the handle to move towards the target position.

[0087] Further, the system continues to adjust the current position of the handle according to the updated fine-tuning instruction, and this process is repeated until the current position of the handle meets the preset accuracy requirement. When the deviation between the current position of the handle and the target position is reduced to within the preset accuracy range, the system considers that the handle has reached the target position sufficiently, and thus the system stops the fine-tuning process and locks the handle in the final position.

[0088] Thus, by using the iterative fine-tuning strategy, the system can ensure that the handle has extremely high accuracy and stability when reaching the target position, improving the flexibility and adaptability of the system, and being able to cope with various deviations and changes that may occur in different environments.

[0089] Optionally, in some embodiments, when adjusting the current position of the handle to the target position according to the target control instruction, further comprising: acquiring a plurality of running state information of the system, and determining whether each running state information exceeds a corresponding preset threshold; if any running state information exceeds the corresponding preset threshold, issuing a preset safety warning information, and controlling the system to stop running.

[0090] It can be understood that in the handle control system of the vehicle, it is crucial to ensure the safety of the adjustment process. Therefore, the embodiments of the present application acquire a plurality of running state information of the system, which includes but is not limited to the current, voltage, temperature, and rotating speed of the motor, etc. For each acquired running state information, the system compares it with the preset threshold. If any running state information exceeds the corresponding preset threshold, the system will immediately determine it as an abnormal situation and issue a preset safety warning information.

[0091] Further, in order to prevent the abnormal situation from further deteriorating or causing greater damage, the system will automatically control the system to stop running, such as cutting off the power supply, stopping the motor from rotating, etc., to ensure that the system is in a safe state.

[0092] It should be noted that the preset threshold corresponding to each running state information of the embodiments of the present application can be set according to the design specifications, safety standards, and long-term running experience of the system, which is not limited here.

[0093] Optionally, in some embodiments, when adjusting the current position of the handle to the target position according to the target control instruction, further comprising: determining whether the track encounters an obstacle according to the plurality of running state information; if the track encounters an obstacle, issuing a preset safety warning information, and controlling the system to stop running.

[0094] Among them, the running state information of the embodiments of the present application also includes the environmental changes near the track detected by the sensor, the abnormal resistance measured by the force sensor, etc.

[0095] Specifically, based on the collected plurality of running state information, the system determines whether the track encounters an obstacle through a preset algorithm or logic. For example, if the motor encounters an abnormal resistance when trying to move the handle, and such resistance exceeds the preset threshold, and other sensors (such as infrared sensors, laser sensors, etc.) also detect that there is an object blocking on the track, the system can determine that the track encounters an obstacle.

[0096] Further, once the system determines that an obstacle is encountered on the track, it will immediately trigger the preset safety warning mechanism, including sounding an alarm, sending an alarm signal to the remote monitoring center, displaying an error code to the user, and the like, to remind the relevant personnel to pay attention and take appropriate measures. Similarly, the system will also immediately control the system to stop running at the same time to ensure that the system is in a safe state.

[0097] Therefore, the embodiments of the present application maintain high safety and reliability in complex and variable operating environments by setting up an obstacle detection function, can quickly respond when encountering obstacles, prevent collision accidents from occurring, and thus protect the safety of equipment and personnel.

[0098] In order to enable those skilled in the art to further understand the handle control method of the vehicle of the embodiments of the present application, the following enumerated embodiments illustrate the implementation steps of the method.

[0099] Specifically, Figure 3 The flow chart of the handle control method of the vehicle of one specific embodiment of the present application is shown in Figure 3 The handle control method of the vehicle includes the following steps:

[0100] (1) acquiring a full-body image of the passenger through an image acquisition module;

[0101] (2) transmitting the acquired image signal to the control system;

[0102] (3) processing the received image signal to extract the height data of the passenger;

[0103] (4) the control unit adjusts the height of the handle through the driving unit according to the calculated height data;

[0104] (5) real-time monitoring the position and height of the handle and feeding back the data to the control unit, and detecting obstacles in the moving process, if an obstacle is encountered, taking safety protection measures and emergency stop mechanism and the like measures, and controlling the system to stop running.

[0105] Therefore, the embodiments of the present application adapt to passengers of different heights by automatically adjusting the height of the handle, reduce the difficulty of getting on and off the vehicle, and improve the convenience. Especially for children and the elderly, it is easier to grasp the appropriate handle, reducing the difficulty of getting on and off the vehicle. In addition, the embodiments of the present application automatically adjust the height of the handle, so that the passenger can better maintain balance and stability when getting on and off the vehicle, reducing the risk of accidental falling. At the same time, in an emergency, such as a vehicle collision, the handle can be quickly adjusted to a safe position to provide additional safety protection for the passenger.

[0106] According to the handle control method of the vehicle provided in the embodiments of the present application, the current position of the handle is acquired, the whole body image information of the passenger is collected, the contour information of the passenger is obtained by processing the whole body image information, the height data of the passenger is obtained by analyzing the contour information through a preset image processing algorithm, the target position of the handle is obtained based on a preset height adjustment strategy according to the height data, the target control instruction is generated according to the target position, and the current position of the handle is adjusted to the target position according to the target control instruction. Therefore, the problems in the prior art that the fixed handle cannot help the people with lower height to get on and off the vehicle, and the difficulty of passengers to escape independently in an emergency is increased, and the like are solved, and the handle control method has high adaptability and intelligent characteristics, can meet the needs of different passengers, improves the convenience and safety of passengers getting on and off the vehicle, and improves the use experience of passengers.
