Detailed ways

The embodiment of the present invention solves the technical problem of how to reduce the impact noise generated when the electric tailgate is opened in a fully locked state by providing a method and device for controlling the electric tailgate of an automobile.

In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the automobile electric tailgate control method of the present embodiment includes:

Step S1, after receiving the opening instruction of the electric tailgate, obtaining the locking state of the electric tailgate;

Step S2, if the locked state of the electric tailgate is fully locked, unlock the electric tailgate and control the electric stay of the electric tailgate to pull the electric tailgate after unlocking the electric tailgate;

Step S3, after the first preset time period, control the electric strut to push open the electric tailgate.

In the traditional electric tailgate control method, after the electric tailgate is unlocked in the fully locked state, the reverse force generated by the sealing structure will make the electric tailgate spring up quickly, resulting in a large impact noise.

In this embodiment, at the moment when the electric tailgate is fully locked, a short reverse current can be applied to the motor of the electric strut to control the reverse rotation of the motor, so that the electric strut pulls the electric tailgate, and the electric tailgate will not Quickly pop up, thereby reducing the impact noise generated when the electric tailgate is fully locked. After the first preset period of time, a positive current is applied to the motor of the electric strut to control the forward rotation of the motor, so that the electric strut pushes the electric tailgate open to complete the opening of the electric tailgate.

The electric tailgate of this embodiment also has a half-lock state. When the electric tailgate is opened in the half-lock state, the reverse force generated by the sealing structure is small, and no large impact noise will be generated. Therefore, the electric tailgate is opened in the half-lock state. There is no need to control the electric tailgate to pull the electric tailgate when opening the door; and if the electric tailgate is controlled to pull the electric tailgate at the moment of unlocking in the half-lock state, it may cause the electric tailgate to enter the full lock state, resulting in the inability to open the electric tailgate . Therefore, after step S1, the method for controlling an electric tailgate of a vehicle in this embodiment further includes: if the locked state of the electric tailgate is a half-lock state, unlocking the electric tailgate and controlling the electric strut to push the electric tailgate open.

Step S3 can directly control the forward rotation of the motor when the motor is reversed, but may cause damage to the gears of the motor. In order to ensure smooth switching of the forward and reverse rotation of the motor, after step S2 and before step S3, the method for controlling an electric tailgate of a vehicle in this embodiment may further include: stopping applying current to the motor of the electric strut after a second preset time period. The second preset duration is the time for applying reverse current to the motor. After stopping the application of current to the motor, the motor will gradually decelerate, and the first preset time period can be set to ensure that the motor can decelerate and stop. In this way, the motor is controlled to rotate forward after the motor stops, which can avoid damage to the gears of the motor.

The above is aimed at the opening method of the electric tailgate. For closing the electric tailgate, if the electric tailgate is closed when the opening is small, in order to make the electric tailgate close against the reverse force generated by the sealing structure, the traditional electric tailgate The tailgate control method needs to apply a lot of current to the motor, which also produces a lot of impact noise. In order to reduce the impact noise generated when the electric tailgate is closed at a small angle, in this embodiment, the method for controlling the electric tailgate of an automobile may further include:

After receiving the closing command of the electric tailgate, obtain the opening of the electric tailgate; if the opening of the electric tailgate is lower than the preset opening threshold, increase the opening of the electric tailgate to above the opening threshold; The opening of the small electric tailgate reaches zero, and in the process of reducing the opening of the electric tailgate from the opening threshold to zero, the electric tailgate is controlled to accelerate to the calibrated speed.

Wherein, the opening threshold may be 30%-50%. This is equivalent to increasing the opening of the electric tailgate to a large angle when the electric tailgate is closed at a small angle, and then controlling the opening of the electric tailgate to be reduced from a large angle to zero, and when the opening of the electric tailgate is changed from open to In the process of reducing the speed threshold to zero, the electric tailgate is controlled to accelerate to a higher speed, so that the electric tailgate can overcome the reverse force generated by the sealing structure and close, which is different from the traditional method that needs to open the electric tailgate from less than In the process when the angle of the degree threshold drops to zero, a large current is applied to the motor to accelerate the electric tailgate rapidly. In this embodiment, the electric tailgate is accelerated when the opening of the electric tailgate drops from the opening threshold to zero. , The acceleration time is long, so there is no need to apply a large current to the motor to accelerate quickly, which can reduce the impact noise generated when the electric tailgate is closed at a small angle. Of course, the speed of the electric tailgate may not reach the calibrated speed when the opening of the electric tailgate drops to zero. In this case, the electric tailgate will always accelerate when the opening of the electric tailgate decreases from the opening threshold to zero. While the opening of the electric tailgate decreases from above the opening threshold to the opening threshold, the electric tailgate can move at an accelerated speed or at a constant speed.

As shown in Figure 2, the present embodiment also provides a vehicle electric tailgate control device, including:

The acquisition module is configured to obtain the locking state of the electric tailgate after receiving the opening instruction of the electric tailgate;

The control module is used to unlock the electric tailgate and control the electric support rod of the electric tailgate to pull the electric tailgate after unlocking the electric tailgate if the lock state of the electric tailgate is fully locked;

The control module is also used to control the electric strut to push open the electric tailgate after the first preset time period.

Furthermore, the control module can also be used for:

After a second preset period of time, stop applying current to the motor of the electric strut.

Further, the obtaining module can also be used to obtain the opening degree of the electric tailgate after receiving the closing command of the electric tailgate;

The control module can also be used to increase the opening of the electric tailgate to above the opening threshold if the opening of the electric tailgate is lower than the preset opening threshold;

The control module can also be used to reduce the opening of the electric tailgate to zero, and control the electric tailgate to accelerate to a calibrated speed during the process of reducing the opening of the electric tailgate from the opening threshold to zero.

Further, the control module can also be used for: if the locked state of the electric tailgate is half-locked, unlock the electric tailgate and control the electric stay to push the electric tailgate open.
