[0002] The space in the car trunk is limited, but we often encounter such a situation. Many things need to be put into the trunk, but it is difficult to evaluate whether the trunk lid can be closed when there are too many things. At this time, we can only try to close it gently to see whether the loaded things will hit the rear windshield and whether the trunk lock can be locked. It is often necessary to reorganize the items and try again. If the items are not placed properly, it is necessary to try repeatedly several times before success, which reduces the efficiency of users in scenarios where many items need to be loaded into the trunk.

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Embodiment 1: Figure 1It is a structural schematic block diagram of a luggage compartment item loading anti-collision reminder system according to an exemplary embodiment, including a millimeter-wave radar, a red light system and a sound reminder system electrically connected to the vehicle body controller respectively, the millimeter-wave radar and the red light system are respectively installed near the luggage compartment lid lock position, the sound reminder system is installed on the inside of the luggage compartment or the inside of the electric tailgate, and the red light system can preferably use a laser red line locator.

[0040] The above-mentioned millimeter-wave radar is used to calibrate the space 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 obtain the current maximum boundary data of the remaining space and establish the 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 position reminder strategy.

[0041] The above current remaining space maximum boundary data is as follows Figure 2 As shown, when the trunk lid is closed naturally, there is a contour, called the natural contour L1. The items in the trunk cannot exceed this contour. Once exceeded, it means that the trunk lid will collide with the items when closed. This natural contour is also the most extreme boundary. The determination of the calibration contour is based on the extreme boundary. The boundary toward the inside of the car is recorded as negative, and the boundary toward the outside of the car is recorded as positive. Then, the contour L2 of the millimeter-wave radar calibration can be calculated as L1-1 cm. This 1 cm means that each point of the natural contour is subtracted 1 cm toward the inside of the car. In this way, a new contour can be formed, which is the calibration contour, so that the trunk lid will not collide with the items in the trunk when closed.

[0042] The millimeter-wave radar is also used to monitor the remaining space inside the trunk corresponding to the position of the trunk lid in real time when the trunk lid is fully opened and feed it back to the body controller. The body controller is also used to receive the remaining space inside the trunk corresponding to the position of the trunk lid, and determine whether the remaining space inside the trunk corresponding to the position of the trunk lid exceeds the current maximum boundary model of the remaining space calibrated at the last moment. If so, it generates the exceeding position data and the exceeding position reminder data, sends the exceeding position data to the red light system, and sends the exceeding position reminder data to the sound reminder system. The red light system is used to generate three-dimensional angle data based on the exceeding position data and the current maximum boundary model of the remaining space and perform corresponding operations to circle the over-limit items with red light. The sound reminder system is used to receive the exceeding position reminder data and control the buzzer to perform corresponding reminder operations.

[0043] Embodiment 2: A control method of a luggage compartment item loading anti-collision reminder system according to an exemplary embodiment includes:

[0044] When the vehicle is started, the body controller sends the anti-collision reminder activation signal to the millimeter-wave radar, red light system and sound reminder system respectively;

[0045] When the trunk lid is closed, the millimeter-wave radar calibrates the space inside the trunk to obtain the maximum boundary data of the current remaining space and feeds it back to the body controller;

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

[0047] The red light system receives the current maximum boundary model of the remaining space and initiates the corresponding position reminder strategy.

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

[0049] The body controller is also used to receive the remaining space inside the trunk corresponding to the position of the trunk lid, and determine whether the remaining space inside the trunk corresponding to the position of the trunk lid exceeds the maximum boundary model of the current remaining space calibrated at the last moment, and if so, generate exceeding position data and exceeding position reminder data, send the exceeding position data to the red light system, and send the exceeding position reminder data to the sound reminder system;

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

[0051] The sound reminder system is used to receive out-of-position reminder data and control the buzzer to perform corresponding reminder operations.

[0052] When the remaining space inside the trunk corresponding to the trunk lid position does not exceed the current maximum boundary model of the remaining space calibrated at the last moment, the remaining space inside the trunk corresponding to the trunk lid position sent by the millimeter-wave radar is re-acquired.

[0053] After the vehicle is started, the millimeter-wave radar will calibrate the space inside the trunk every time the trunk lid is closed to obtain the current maximum boundary data of the remaining space and send it to the body controller. The body controller obtains the current maximum boundary data of the remaining space and establishes the current maximum boundary model of the remaining space based on it and deletes the last established maximum boundary model of the remaining space, and sends the current maximum boundary model of the remaining space to the red light system. The red light system receives the current maximum boundary model of the remaining space and deletes the last received current maximum boundary model of the remaining space.
