Description

Technical Field

[0001] This invention discloses a luggage loading anti-collision reminder system, control method, and vehicle, belonging to the field of automotive technology. Background Technology

[0002] Car trunk space is limited, but we often encounter situations where we need to put a lot of things in the trunk. However, with so many items, it's difficult to assess whether the trunk lid can be closed. In such cases, we can only try closing it gently to see if the items will hit the rear windshield and if the trunk lock can be engaged. We often need to rearrange the items and try again. If the items are not arranged properly, we have to try several times before we can succeed, which reduces the efficiency for users in scenarios where they need to pack many items into the trunk. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention proposes a luggage loading anti-collision reminder system, control method, and vehicle, solving the efficiency problem for users in scenarios where many items need to be loaded into their luggage.

[0004] The technical solution of the present invention is as follows:

[0005] According to a first aspect of the present invention, a luggage loading anti-collision reminder system is provided, comprising a millimeter-wave radar, a red light system and an audible reminder system respectively electrically connected to a vehicle body controller, wherein the millimeter-wave radar and the red light system are respectively installed near the luggage compartment lid lock position, and the audible reminder system is installed inside the luggage compartment or inside the power tailgate.

[0006] Preferably, the millimeter-wave radar is used to perform spatial calibration inside the trunk when the trunk lid is closed to obtain the current maximum boundary data of the remaining space and feed it back to the body controller; the body controller is used to acquire the current maximum boundary data of the remaining space, build a current maximum boundary model of the remaining space based on it, and send it to the red light system; the red light system is used to receive the current maximum boundary model of the remaining space and activate the corresponding location reminder strategy.

[0007] The millimeter-wave radar is also used to monitor the remaining space inside the trunk corresponding to the trunk lid position in real time when the trunk lid is fully open and to feed it back to the vehicle body controller. The vehicle body controller is also used to receive the remaining space inside the trunk corresponding to the trunk lid position and to determine whether the remaining space inside the trunk corresponding to the trunk lid position exceeds the maximum boundary model of the current remaining space calibrated at the previous moment. If so, it generates out-of-position data and out-of-position reminder data, sends the out-of-position data to the red light system, and sends the out-of-position reminder data to the sound reminder system.

[0008] The red light system is used to generate three-dimensional angle data based on the out-of-position data and the current remaining space maximum boundary model, and to perform corresponding operations.

[0009] The sound alert system is used to receive out-of-location alert data and control the buzzer to perform the corresponding alert operation.

[0010] According to a second aspect of the present invention, a control method for a luggage loading anti-collision reminder system is provided, applied to the luggage loading anti-collision reminder system described in the first aspect, comprising:

[0011] When the vehicle starts, the body controller sends a collision avoidance warning activation signal to the millimeter-wave radar, the red light system, and the sound warning system, respectively.

[0012] The millimeter-wave radar performs spatial calibration inside the trunk when the trunk lid is closed, obtains the maximum boundary data of the current remaining space, and feeds it back to the vehicle controller.

[0013] Obtain the current maximum boundary data of the remaining space, build a model of the current maximum boundary of the remaining space based on it, and send it to the red light system;

[0014] The red light system receives the current maximum boundary model of the remaining space and activates the corresponding location reminder strategy.

[0015] Preferably, it also includes:

[0016] When the trunk lid is fully open, the millimeter-wave radar monitors the remaining space inside the trunk corresponding to the position of the trunk lid in real time and feeds it back to the vehicle controller.

[0017] The vehicle body controller is also used to receive the remaining space inside the trunk corresponding to the trunk lid position, and determine whether the remaining space inside the trunk corresponding to the trunk lid position exceeds the maximum boundary model of the current remaining space calibrated at the previous moment. If so, it generates out-of-position data and out-of-position reminder data, sends the out-of-position data to the red light system, and sends the out-of-position reminder data to the sound reminder system.

[0018] The red light system is used to generate three-dimensional angle data based on the out-of-position data and the current remaining space maximum boundary model, and to perform corresponding operations.

[0019] The sound alert system is used to receive out-of-location alert data and control the buzzer to perform the corresponding alert operation.

[0020] Preferably, if the remaining space inside the suitcase corresponding to the position of the suitcase lid does not exceed the maximum boundary model of the current remaining space calibrated at the previous moment, then the remaining space inside the suitcase corresponding to the position of the suitcase lid transmitted by the millimeter-wave radar is reacquired.

[0021] Preferably, after the vehicle is started, the millimeter-wave radar will perform spatial calibration inside the trunk each time the trunk lid is closed to obtain the maximum boundary data of the current remaining space and send it to the vehicle body controller.

[0022] The vehicle body controller acquires the current maximum boundary data of the remaining space and establishes a current maximum boundary model of the remaining space based on it, deletes the previously established maximum boundary model of the remaining space, and sends the current maximum boundary model of the remaining space to the red light system.

[0023] The red light system receives the current maximum boundary model of the remaining space and deletes the previously received maximum boundary model of the remaining space.

[0024] According to a third aspect of the present invention, a vehicle is provided, comprising:

[0025] One or more processors;

[0026] Memory for storing the one or more processor-executable instructions;

[0027] Wherein, the one or more processors are configured as follows:

[0028] Perform the method described in the first aspect of the embodiments of the present invention.

[0029] According to a fourth aspect of the present invention, a non-transitory computer-readable storage medium is provided, wherein when instructions in the storage medium are executed by a processor of a terminal, the terminal is enabled to perform the method described in the first aspect of the present invention.

[0030] According to a fifth aspect of the present invention, an application product is provided that, when the application product is running on a terminal, causes the terminal to execute the method described in the first aspect of the present invention.

[0031] The beneficial effects of this invention are as follows:

[0032] This invention provides a luggage loading anti-collision reminder system, control method, and vehicle. Utilizing the occupancy detection function of millimeter-wave radar, when a user loads a large number of items into the luggage, if the items exceed the luggage's limits, the millimeter-wave radar will issue an audible reminder and simultaneously circle the area exceeding the limits with a red light, making it easy for the user to pinpoint the over-limited area. This effectively prevents items inside the luggage from colliding with the luggage lid when it is closed, greatly improving the efficiency of loading items under these conditions.

[0033] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the invention. Attached Figure Description

[0035] Figure 2 This is a schematic block diagram illustrating the outline of a luggage item loading anti-collision reminder system according to an exemplary embodiment. Detailed Implementation

[0036] 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.

[0037] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] Example 1: Figure 1This is a schematic block diagram of a luggage loading anti-collision reminder system according to an exemplary embodiment, including a millimeter-wave radar, a red light system and an audible reminder system, which are electrically connected to the vehicle body controller. The millimeter-wave radar and the red light system are respectively installed near the luggage compartment lid lock position, and the audible reminder system is installed inside the luggage compartment or inside the power tailgate. The red light system can preferably be a laser red line locator.

[0040] The millimeter-wave radar is used to perform spatial calibration inside the trunk when the trunk lid is closed, obtain the maximum boundary data of the current remaining space, and feed it back to the body controller. The body controller is used to obtain the maximum boundary data of the current remaining space, build a model of the maximum boundary of the current remaining space, and send it to the red light system. The red light system is used to receive the model of the maximum boundary of the current remaining space and activate the corresponding location reminder strategy.

[0041] When the trunk lid closes naturally, there is a contour, called the natural contour L1. Items inside the trunk cannot exceed this contour; otherwise, the trunk lid will collide with the items when it closes. This natural contour is the ultimate limit. The calibration contour is determined based on this ultimate limit. The boundary pointing inwards from the vehicle is recorded as negative, and the boundary pointing outwards is recorded as positive. The millimeter-wave radar calibration contour L2 can be calculated as L1 - 1 cm. This 1 cm refers to subtracting 1 cm from each point of the natural contour inwards from the vehicle, thus forming a new contour, which is the calibration contour. This ensures that the trunk lid will not collide with the items inside the trunk when it closes.

[0042] Millimeter-wave radar is also used to monitor the remaining space inside the trunk corresponding to the trunk lid position in real time when the trunk lid is fully open and to feed this information back to the vehicle control system. The vehicle control system receives this remaining space data and determines whether it exceeds the previously calibrated maximum boundary model of the remaining space. If so, it generates out-of-bounds data and an out-of-bounds warning, sending the out-of-bounds data to the red light system and the out-of-bounds warning data to the audible warning system. The red light system generates three-dimensional angle data based on the out-of-bounds data and the current maximum boundary model of the remaining space and performs corresponding operations to circle the out-of-bounds items with red lights. The audible warning system receives the out-of-bounds warning data and controls the buzzer to perform the corresponding warning operation.

[0043] Example 2: A control method for a luggage loading anti-collision reminder system according to an exemplary embodiment includes:

[0044] When the vehicle starts, the body control unit sends a collision avoidance warning activation signal to the millimeter-wave radar, the red light system, and the sound warning system, respectively.

[0045] With the trunk lid closed, the millimeter-wave radar performs spatial calibration inside the trunk to obtain the maximum boundary data of the current remaining space and feeds it back to the vehicle controller.

[0046] Obtain the current maximum boundary data of the remaining space, build a model of the current maximum boundary of the remaining space based on it, and send it to the red light system;

[0047] The red light system receives the maximum boundary model of the remaining space and activates the corresponding location alert strategy.

[0048] When the trunk lid is fully open, the millimeter-wave radar monitors the remaining space inside the trunk corresponding to the position of the trunk lid in real time and feeds it back to the vehicle controller.

[0049] The vehicle controller is also used to receive the remaining space inside the trunk corresponding to the trunk lid position, and determine whether the remaining space inside the trunk corresponding to the trunk lid position exceeds the maximum boundary model of the current remaining space calibrated at the previous moment. If so, it generates out-of-position data and out-of-position reminder data, sends the out-of-position data to the red light system, and sends the out-of-position reminder data to the sound reminder system.

[0050] The red lighting system is used to generate three-dimensional angle data based on the out-of-position data and the current maximum boundary model of the remaining space, and to perform corresponding operations.

[0051] The sound alert system is used to receive out-of-location alert data and control the buzzer to perform the corresponding alert operation.

[0052] If the remaining space inside the suitcase corresponding to the above-mentioned suitcase lid position does not exceed the maximum boundary model of the current remaining space calibrated at the previous moment, then the remaining space inside the suitcase corresponding to the suitcase lid position transmitted by the millimeter-wave radar is reacquired.

[0053] Upon vehicle startup, the millimeter-wave radar performs spatial calibration inside the trunk each time the trunk lid is closed to obtain the maximum remaining space boundary data, which is then sent to the body controller. The body controller acquires this maximum remaining space boundary data, builds a model of the maximum remaining space boundary based on it, deletes the previously built model, and sends this model to the red light system. The red light system receives the current maximum remaining space boundary model and deletes the previously received model.
