[0002] Currently, many car trunks on the market are designed to open and close using either an electric motor or a hydraulic system. Especially in high-end vehicles, the motor control is highly precise, with control curves and limit point settings carefully considered for the user. For example, the opening height cannot be too low, allowing for easy loading and unloading at the rear of the vehicle; conversely, the opening height cannot be too high, taking into account obstructions such as fire sprinklers above the vehicle.

[0003] However, the actual parking locations of vehicles are not always ideal, especially on uneven roads, which cause the vehicle to tilt. This reduces the adaptability of the pre-set motor control curves and limit points to the current vehicle posture, and may even lead to malfunctions.

[0004] Therefore, a solution is needed that can adjust the pre-set motor control strategy according to the actual changes in the vehicle's current posture, so that the opening and closing of the vehicle's trunk is not affected by the vehicle's posture. Summary of the Invention

[0050] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Figure 1 This is a flowchart of a vehicle trunk lid control method provided by one or more embodiments of the present invention.

[0052] like Figure 1 As shown, the vehicle trunk lid control method includes:

[0053] Step S1: Obtain the standard control strategy information for the vehicle's trunk lid;

[0054] Step S2, the standard control strategy information includes the torque control curve and stroke control range of the motor that drives the trunk lid to open or close under the standard state of the vehicle;

[0055] Step S3: Obtain vehicle status information;

[0056] Step S4: Generate strategy adjustment information for the standard control strategy based on the vehicle status information;

[0057] Step S5: Based on the current vehicle status and the corresponding strategy adjustment information, adjust the standard control strategy to control the motor that drives the vehicle's trunk lid to open or close.

[0058] The above solution achieves the following beneficial technical effects:

[0059] This application adjusts the torque of the motor driving the trunk according to the vehicle's posture to correspond to the load change, thus solving the problem of insufficient torque of the trunk lid motor caused by the vehicle tilting when parked on a sloped road.

[0060] This application adjusts the limit point of the motor driving the trunk according to the vehicle's posture, thereby solving the problem of the trunk opening too high and hitting the garage fire sprinkler head when parked on a sloping road.

[0061] This application adjusts the torque of the motor driving the trunk according to the size of the window opening, thus solving the problem of incomplete closure caused by air pressure blockage during the trunk closing process.

[0062] This application employs different strategies to adjust the motor torque of the top-opening or side-opening trunk lid according to the vehicle's longitudinal or lateral tilt state, thereby ensuring a reliable closing process.

[0063] Specifically, the standard vehicle state can be defined as the vehicle being level with all windows closed. A corresponding standard control strategy for the trunk lid can be set, including the motor torque control curve and travel control range for opening and closing the trunk lid in this standard state. The standard trunk lid control strategy typically needs to consider whether the opening height will be too high (e.g., with an upward-opening trunk lid), potentially causing impact from objects above, and the load changes during trunk lid opening (e.g., a larger load when an upward-opening trunk lid is opened to a horizontal position). Changes in vehicle posture can cause the trunk lid to not actually be level when it reaches its intended horizontal position, and the height after full opening may exceed the original position. Therefore, the corresponding motor torque control curve and travel range need to be adjusted.

[0064] Information about the vehicle's parking posture, such as the vehicle's tilt angle, can be obtained using onboard gyroscope attitude sensing technology. Information about the opening and closing status of the front and rear windows, as well as the degree of opening, can be obtained using window position sensors.

[0065] For example, when a vehicle deviates from its standard operating state, the demands on the torque control curve and travel control range change. Adjustments can be made to the torque control curve and travel control range in the standard control strategy to adapt to the current vehicle condition.

[0066] The trunk lid is usually driven directly by an electric motor or indirectly by a hydraulic system. When the load increases, the torque output of the electric motor needs to be increased.

[0067] Typically, top-opening trunk lids are close to a cantilever structure. When the trunk lid is in a horizontal position, the motor load is relatively large, and the motor needs to output a correspondingly high torque. Side-opening trunk lids, on the other hand, are not cantilever structures and are basically kept horizontal. The motor load is relatively even, but when the ground tilts, it has a greater impact on the opening and closing torque of the side-opening trunk lid.

[0068] For example, when the trunk lid is first opened and when it is finally closed, there is a process of squeezing and impacting with the locking tongue and other mechanisms, which requires a large torque to ensure smooth opening or closing. The opening and closing of the car windows affects the efficiency of air pressure blocking in the car, so the peak value of the motor torque control curve must be adjusted accordingly for the opening and closing of the car windows.

[0069] For example, when the car windows are completely closed, the cabin forms a sealed shell. During the final closing stage of the trunk lid, the lack of air circulation causes a sharp increase in internal pressure, increasing the load on the motor. This requires the motor to output a larger torque while slowing down the closing speed to ensure complete closure. However, when the car windows are open, the cabin forms an air passage, and the trunk lid is less obstructed by airflow, so the motor does not need to output a large torque to close completely.

[0070] The initial vehicle data is set based on typical stable conditions to form a standard control strategy, which includes pre-set torque control curves and travel control ranges. For example, when the vehicle is parked on a level surface, the change in motor load is measured as the trunk lid opens, fully opens, and then closes, and the control torque output curve is matched accordingly. The standard control strategy also includes designing the motor step distance and the trunk lid opening angle within the travel control range to ensure the trunk lid opens at a reasonable angle. For instance, considering the low ceiling of a garage with fire sprinklers overhead, the trunk lid opening angle should not be too high, and ease of entry and exit during loading and unloading should also be considered.

[0071] However, when the terrain changes (such as on a garage ramp), the vehicle is tilted. For example, when the top-opening trunk lid is opened to a horizontal position, the opening angle is different from the original horizontal position. If the motor is still driven by the original torque control curve, it may not only affect the achievement of the ideal opening angle, but may also cause the motor to continuously output and cause serious heat generation.

[0072] Alternatively, if the vehicle tilts to one side, and the side-opening trunk lid motor outputs torque control according to the standard control strategy under relatively uniform load conditions, the motor may not have enough torque to close properly or may not decelerate effectively, potentially causing injury to the user.

[0073] For example, when the vehicle is going downhill, the pre-set opening angle of the trunk lid may exceed the preset position, such as if it hits a consumer nozzle. Therefore, the motor's step stroke control range needs to adapt to the current step limit point. Rotary encoders, limit switches, Hall effect switches, proximity switches, etc., can be used to detect motor rotation or door opening angles.

[0074] Therefore, the torque control curve and travel control range need to be adjusted according to the current vehicle condition. For example, the torque control curve can be shifted according to the slope of the ground to ensure that the trunk lid does not suffer from insufficient torque due to changes in slope, resulting in incomplete opening or incomplete opening.

[0075] Since the vehicle's structure and drive components have not undergone fundamental changes, the vehicle's state is affected only by the environment. For example, changes in terrain may cause the motor torque control curve and travel control range in the standard control strategy to become unsuitable for the current vehicle posture. Therefore, the motor torque control curve and travel control range in the standard control strategy can be adjusted to adapt to the current state. This can be done by shifting the torque control curve or changing the limit points of the travel control range, so that the opening and closing of the vehicle's trunk lid and the degree of window opening can adapt to the current vehicle posture.

[0076] In this embodiment, the strategy adjustment information for generating the standard control strategy based on vehicle status information includes:

[0077] Vehicle status information includes vehicle parking posture information;

[0078] The offset of the motor torque control curve is adjusted according to the angle of the vehicle's deviation from the horizontal plane when it is parked on the ground.

[0079] Specifically, for example, if the vehicle's gyroscope detects that the vehicle is on an uphill slope, the peak of the torque control curve for the trunk lid of an upward-opening vehicle needs to be adjusted to correspond to the change in slope angle. This can be achieved by shifting the peak of the motor's torque control curve, which corresponds to the original position of the trunk lid opening, to the latter half of the opening. Through this adjustment, the peak of the torque control curve can be aligned with the actual horizontal state of the trunk lid.

[0080] In this embodiment, the strategy adjustment information for generating the standard control strategy based on the vehicle status information further includes:

[0081] The offset of the motor travel control range is adjusted according to the angle of the vehicle's deviation from the horizontal plane when it is parked on the ground.

[0082] Specifically, for example, if the vehicle's onboard gyroscope detects that the vehicle is on a downhill slope, to prevent the trunk lid of an upward-opening vehicle from hitting objects on top when fully opened, the travel control range is shifted forward by half compared to when the vehicle is level. This prevents the trunk lid from exceeding its original highest point after opening. Through this adjustment, the motor's stepping range can be adjusted to prevent the vehicle's trunk lid from hitting objects above.

[0083] In this embodiment, the strategy adjustment information for generating the standard control strategy based on the vehicle status information further includes:

[0084] Vehicle status information includes information about the open / closed status of the vehicle's windows;

[0085] Adjust the peak value of the motor torque control curve based on the window opening status.

[0086] Specifically, when one or more windows are open, the opening area increases, improving airflow inside the vehicle. This reduces the torque required during the final closing phase, lowering the peak value of the torque control curve. Regardless of whether the windows are open or closed, the trunk lid closing or locking process requires significant torque in the final stage, sometimes even resulting in an impact-type closure. Therefore, the impact on the motor torque control curve is primarily the peak torque value, with almost no effect on the motor's travel range.

[0087] However, it cannot be ruled out that external airflow affects the air pressure changes inside the car, especially when the windows are open, which would require more complex offset processing and peak-to-peak adjustment of the torque control curve.

[0088] In this embodiment, adjusting the offset of the motor torque control curve based on the angle of the vehicle's deviation from the horizontal plane when parked includes:

[0089] Vehicle parking posture information includes longitudinal posture angle information and lateral posture angle information;

[0090] Adjust the offset of the torque control curve of the top-opening trunk lid motor based on the vehicle's longitudinal attitude angle information;

[0091] The offset of the torque control curve of the side-opening trunk lid motor is adjusted based on the vehicle's lateral attitude angle information.

[0092] Specifically, trunk lids are divided into top-opening and side-opening types. Top-opening trunk lids are sensitive to changes in the vehicle's longitudinal attitude angle, while side-opening trunk lids are sensitive to changes in the vehicle's lateral attitude angle. The offset motor torque control curve and stroke control range, as well as the peak and peak values, can be adjusted according to the vehicle's specific attitude on a slope and the type of trunk lid matched to the vehicle.

[0093] For example, if a side-opening trunk lid opens to the right and the vehicle happens to be tilted to the left, it is necessary to increase the peak value of the torque control curve during the opening phase. During the closing phase, in addition to increasing the peak value of the torque control curve, it is also necessary to control the direction of the motor's torque output to prevent the side-opening trunk lid from closing due to gravity, which could cause injury to the user.

[0094] In this embodiment, adjusting the offset of the motor travel control range according to the angle of the vehicle's parking position relative to the horizontal plane includes:

[0095] The limit points of the motor travel control range for the top-opening trunk lid are adjusted based on the vehicle's longitudinal posture angle information.

[0096] Specifically, for example, the opening angle of a vehicle's trunk lid may be limited at a certain docking platform, such as a tubular docking and unloading platform. Alternatively, multiple limit points may be pre-set on the motor's stroke curve for loading and unloading goods. Changes in vehicle posture cause changes in the loading and unloading docking position. Therefore, it is necessary to offset the limit points according to the current vehicle posture to ensure that the opening angle of the vehicle's trunk lid matches the original loading and unloading channel.
