detailed description

In order to further explain the technical means and effects that the present invention adopts to achieve the intended purpose of the invention, the specific implementation, structure and features of the intelligent automatic opening system for the trunk of a car proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. And its effect, detailed description is as follows.

As shown in FIG. 1 , the intelligent automatic opening system of the automobile trunk of the present invention includes a keyless entry module 1 , a reversing radar module 2 and a vehicle body control module 3 . The keyless entry module 1 , the reversing radar module 2 and the vehicle body control module 3 are electrically connected via a bus.

The keyless entry module 1 is mainly used to ensure that the trunk can only be opened when the driver himself operates, so as to ensure the safety of the belongings in the car. After the car is turned off, the keyless entry module 1 is turned on.

The reversing radar module 2 is used for recording and detecting user signals. The reversing radar module 2 includes a plurality of radars, and existing automobiles are generally equipped with four radars or three radars. The reversing radar module 2 stores the predetermined storage sequence in the reversing radar module 2 through the driver's prior setting. After the reversing radar module 2 completes the memory of the stored sequence, if the same sequence as the stored sequence is detected again under certain conditions , a trunk opening request will be sent to the body control module 3 to achieve the purpose of opening the trunk. That is to say, when the reversing radar module 2 is in the detection state and detects the recording sequence again, it is considered that the driver has an intention indication to open the trunk. For example, as shown in Figure 2, between the left rear wheel 4 and the right rear wheel 5 of the car, there are radar one, radar two, radar three, and radar four in sequence, and the serial numbers corresponding to these four radars are 1, 2, 3, 4. The driver's pre-stored storage sequence in the reversing radar module 2 is 1234321. When the driver approaches the vehicle, he moves from radar 1 to radar 4, and then from radar 4 to radar 1. The current sequence with a value of 1234321 is generated. If the current sequence matches the pre-stored storage sequence, it can be considered that the driver intends to open the trunk. On the contrary, if the generated current sequence does not match the stored sequence, it is not considered that the driver intends to open the trunk. The method is mainly used to prevent misoperation and ensure certain security.

As shown in Figure 3, the specific working process of the present invention is as follows: when the driver turns off the engine and leaves the car within a certain range, the keyless entry module 1 is turned on, and the system is activated. At this time, it can be considered that the driver has parked for shopping or picked up objects. . When the keyless entry module 1 judges that the driver carries the one-button start key and approaches the car again, the system will start the reversing radar module 2 for detection. If the car door or the trunk is opened, the system believes that the driver does not need to The trunk is opened automatically intelligently, and the reversing radar module 2 is turned off at this time, and the workflow ends.

But if the state that the car door or the trunk is opened does not occur, and the reversing radar module 2 detects that the storage sequence identical to that set in advance occurs, then the reversing radar module 2 requests the body control module 3 to automatically open the trunk. It can be considered that the driver holds the object with both hands and does not have any extra hands to perform the zipper action. According to the previous setting, the radar corresponding to the storage sequence preset by the reversing radar module 2 is walked sequentially, that is, it is considered to send a signal to the body control module 3 to make Turn on the trunk action.

That is, the keyless entry module 1 , the reversing radar module 2 , and the vehicle body control module 3 of the present invention activate the rear modules sequentially according to the judgment of the front modules.

The present invention completes the intelligent automatic opening function of the new functional trunk through design and combination. That is, by simplifying the intelligent opening system of the car trunk, the reliability of the switch operation is improved without increasing the component cost.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Anyone familiar with this field Those skilled in the art, without departing from the scope of the technical solution of the present invention, may use the technical content disclosed above to make some changes or modify them into equivalent embodiments with equivalent changes, but as long as they do not depart from the technical solution of the present invention, the Technical Essence Any simple modifications, equivalent changes and modifications made to the above embodiments still fall within the scope of the technical solution of the present invention.
