Detailed Description
Other advantages and effects of the present invention will become apparent to those skilled in the art from the disclosure of the present specification, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings and preferred embodiments. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It should be understood that the preferred embodiments are illustrative of the invention only and are not limiting upon the scope of the invention.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The embodiment provides a method for opening an automobile door, as shown in fig. 1, the method is based on a gyroscope of a mobile terminal, the automobile door in the embodiment is an electric side door, and the starting method specifically includes:
firstly, real-name authentication of the mobile terminal on a vehicle machine needs to be opened, and a distance between the mobile terminal and the vehicle machine, a rotation angle theta and a rotation angular velocity alpha data of the mobile terminal and a data interaction channel of a vehicle body controller are opened. The mobile terminal in this implementation is provided with a gyroscope.
The mobile terminal is paired with the vehicle end, and then information interaction between the mobile terminal and the vehicle is realized, specifically:
when a vehicle owner carrying a common mechanical key approaches the vehicle for a set distance, a signal of a radio frequency generator inside the mechanical key is received by an antenna in a handle, a TBOX module on the vehicle is awakened, and a BT communication module inside the mechanical key starts to work. The position information of the mobile terminal forms a torrent file in a B-code form, the torrent file is sent to the cloud end through a network channel, and a tracker server in the torrent file identifies the unique identifier and the IP address sent by a BT communication module in the TBOX.
After the two are successfully paired, an info-hash part in the tracker server confirms the check code information carried by the BT communication chunk, and after the confirmation is successful, the TB communication combination end is allowed to download data; after the BT communication block receives the reply of allowing downloading, a started command and a download command are sent to download data containing the position information of the mobile terminal; after data are analyzed, data transmission is carried out on a CAN line by using a USB interface of a TBOX chunk, and high and low levels containing protocol information and mobile terminal position data are formed; the level is identified by a CAN interface transceiver of the vehicle body control module, read and input into a CPU of the vehicle body controller,
a user holds the mobile terminal with the gyroscope to move to the automobile, the mobile terminal is rotated, and the mobile terminal end collects the position of the mobile terminal of the user for many times through the gyroscope and sends the position to the automobile end. This is because the angle of the rotating mobile terminal needs to be calculated by at least the position information of two mobile terminals, and the rotational acceleration of the mobile terminal needs to be calculated by at least the angle of two rotating mobile terminals.
When the mobile terminal is out of the set detection range of the vehicle end, the vehicle end does not process the rotation action information sent by the mobile terminal, and when the mobile terminal enters the set detection range of the vehicle end, the CPU can convert the rotation angular velocity alpha and the angle theta of the rotation action of the mobile terminal according to the input multiple groups of data.
When mobile terminal's rotation action accords with preset requirement, then the door is opened, and the preset requirement of this embodiment is for both satisfying condition a, also satisfying condition b, wherein:
the condition a is: the rotation angle theta also reaches the set rotation angle;
the condition b is: the rotational angular velocity alpha reaches the set angular velocity value.
If both the condition a and the condition b are satisfied, the door is opened, and if either the rotation angular velocity a reaches the set angular velocity value or the rotation angle θ does not reach the set rotation angle, the power side door is not opened.
In this embodiment, the electric side door can be driven to open only when the rotational angular velocity and the rotational angle of the mobile terminal respectively reach the set angular velocity value and the set rotational angle, so that the mode of opening the electric side door has an error-proof mechanism.
In this embodiment, the method for opening the electric side door includes:
and when the mobile terminal is in the set detection range and the rotation angle theta and the rotation angular velocity alpha respectively reach the set rotation angle and the set angular velocity, driving the door to electrically open and half lock. At this time, the full-lock signal is changed from 1 to 0.
When the controller detects that the full-locking signal is changed from 1 to 0, the controller drives the electric driver to be powered on, so that the electric opening of the vehicle door is realized, and the controller converts the opening angle of the vehicle door through a square wave signal fed back by a Hall sensor on a motor of the electric driver. When the door lock of the vehicle door is completely separated from the lock pin, the door lock half-locking signal switching electric signal is changed from 1 to 0.
When the controller detects that the switch electric signal of the half-lock signal of the door lock is changed from 1 to 0, the controller drives the electric opening motor in the lock body to reversely rotate and reset.
When the controller detects that the vehicle door is opened to reach a full-opening state, the electric driver is controlled to brake and hover.

The present embodiment provides an opening system for an automobile door, which is based on the opening method for an automobile door provided in embodiment 1, as shown in fig. 2, and includes a distance detection module 2 and an automobile body opening judgment module 3, both of which are integrated on an automobile body controller 1.
The distance detection module 2 is configured to detect a distance between the mobile terminal and the vehicle end, if the mobile terminal is outside a set detection range of the vehicle end, the CPU of the vehicle body controller 1 does not process data transmitted by the mobile terminal, and if the mobile terminal is within the set detection range of the vehicle end, the CPU of the vehicle body controller 1 processes data transmitted by the mobile terminal.
The door opening judging module 3 is configured to receive a rotation action of the mobile terminal, and based on a CPU processing result, judge whether the rotation action of the mobile terminal meets a preset requirement, and if the rotation action meets the preset requirement, drive the door lock to electrically open the motor to start the door, the rotation action of the mobile terminal meets the preset requirement, which means that the rotation angle of the mobile terminal reaches a preset angle, the rotation angular velocity of the mobile terminal reaches a preset angular velocity, or a combination of the two.
