The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

The invention provides a method for opening an electric tail gate of an electric automobile based on face recognition detection, wherein the main flow is that firstly, face feature information of a user is collected through a T-box terminal and is input into a database, the terminal learns relevant features of the face feature, and information of a plurality of users can be collected according to customer requirements. After the user with learning authentication passes through the fixed camera, judging and identifying whether the user accords with the prestored information. If the face verification passing signal is passed, the camera forwards the verification completion information to the vehicle body controller module, and the vehicle body controller module forwards a door opening request to the controller module of the electric tail door for processing through a field bus after receiving the face verification passing signal. The electric tail gate controller module which receives the information drives the electric stay bar to execute the opening action, and the Hall sensor continuously records the position information in the stay bar process until the complete opening action of the electric tail gate is completed.

The invention is described in further detail below with reference to the attached drawing figures:

referring to fig. 1, a flowchart of a method for automatically opening an electric tail gate of an automobile in the invention specifically includes the following steps:

s1, acquiring face characteristic information of a user, and obtaining pre-stored information of the user after characteristic learning of the face characteristic information.

S2, storing pre-stored information of a user, simultaneously executing the action of opening the electric tail gate, and storing the enabling state position of the electric tail gate.

S3, acquiring face verification information, and judging and identifying whether the face verification information accords with the pre-stored information of the user.

And S4, if the face verification information accords with the pre-stored information of the user, judging whether the electric tail gate is at the closed initial position or not.

And S5, if the electric tail gate is at the closed initial position, controlling the electric tail gate to be opened until the electric tail gate is opened to the electric tail gate enabling state position.

The electric tail gate is opened and is supported and opened by driving the electric stay bar through the motor, in the opening process, position information of the electric stay bar is collected in real time, when an anti-pinch signal appears, the electric stay bar stops supporting and opening and runs reversely until the anti-pinch signal disappears, and the motor continues to drive the electric stay bar to support and open. If the electric tail gate is interfered by external factors in the opening process and can not reach the enabling state position of the electric tail gate, the electric tail gate is controlled to be closed, and whether the electric tail gate is at the closing initial position is judged again.

Referring to fig. 2, a flowchart of a specific implementation of opening an electric tail gate of an automobile in the present invention specifically includes the following steps:

step 1, firstly, facial feature information of a user is acquired through a mobile terminal, head motion information is used for closing a back door operation, back door opening operation is recorded and executed for the first time, and a system can automatically memorize back door opening angle positions.

Step 2, the user walks to the tail of the automobile, stands ready to open the electric tail gate operation in the detection range of the camera, and at least stands for 3 seconds when the camera detects and identifies the face of the user, so that the operation of opening the electric tail gate can be executed, and the false triggering of the face to open the electric tail gate is prevented.

And 3, after the face verification information is identified, the car networking control unit T-box transmits an electric tail gate opening signal to the car body controller unit BCM, and the car body controller unit BCM receives the signal of the car networking control unit T-box and forwards the signal to the electric tail gate control module ECU.

Step 4, after receiving the switch signal, the electric tail gate control module ECU judges whether the electric tail gate is at a closed initial position or not by a Hall sensor, and if the electric tail gate is at a non-initial position state, the flow is ended; if the motor is in the initial position state, the motor drives the electric stay bar to start working.

And 5, continuously acquiring position information by the Hall sensor in the executing process of the electric stay bar action, stopping the electric stay bar action and reversely running for a section to form when an anti-pinch signal appears, and continuing to open after the anti-pinch signal disappears.

And 6, feeding back the detected position information to an ECU (electronic control Unit) by the Hall sensor until the electric tail gate is opened to a memory enabling state position, and stopping sucking and operating by the motor when the signal is in a qualified state. If the electric tail gate fails to move to the memory enabling position due to interference of external factors, the electric tail gate control module ECU automatically closes the electric tail gate and re-executes the steps 4-6.
