[0020] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless otherwise specifically stated.
[0021] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.
[0022] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.
[0023] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0024] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0025] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0026] When the weather outside is extremely cold, the electric sliding door of a car parked outdoors may not open normally due to freezing.
[0027] Specifically, when the driver completes the official business that needs to be handled and drives away, the sliding door is fixed to the door frame due to ice between the sliding door and the door frame, and the motor cannot drive the sliding door to open.
[0028] When people were waiting in the car for the official business personnel to return, they were unable to get out of the car because the sliding door was fixed to the door frame by ice, which seriously affected the driving and passenger experience.
[0029] In view of this, the present disclosure proposes a method, device and medium for opening an electric sliding door of an automobile, which can open an electric sliding door of an automobile that is frozen in cold weather, thereby improving the driving experience.
[0030] Figure 1 FIG. 1 is a flow chart showing a method for opening an electric sliding door of an automobile according to some embodiments of the present disclosure. Figure 1 As shown, the vehicle electric sliding door opening method includes steps 110 to 160.
[0031] In step 110 , a sliding door opening instruction is obtained.
[0032] There are two ways to obtain the sliding door opening instruction. The first way is to obtain the instruction from the central control, such as the person in the car can issue the sliding door opening instruction through the central control screen; the second way is that the person outside the car can issue the sliding door opening instruction through the mobile terminal. Specifically, if it is the first way, first establish a communication connection with the car central control, then receive the sliding door opening instruction sent from the car central control, and return the sliding door opening instruction. If it is the second way, the person outside the car sends the sliding door opening instruction to the car central control through the mobile terminal, and the sliding door opening instruction is forwarded by the car central control.
[0033] In step 120 , based on the sliding door opening instruction, a driving motor for opening the sliding door is controlled to rotate.
[0034] The drive motor is used to drive the sliding door to slide. By detecting the rotation speed of the drive motor, it is possible to indirectly know whether the sliding door is frozen. If the rotation speed is zero, it indicates that the sliding door has been frozen and cannot be opened normally.
[0035] In step 130 , the rotation speed of the driving motor is detected.
[0036] In step 140, if the rotation speed is equal to zero, the heating strips mounted on the edge of the sliding door are controlled to heat the ice.
[0037] From the above, it can be known that when the rotation speed of the driving motor is equal to zero, it indicates that the sliding door is frozen by ice. The ice is heated by the heating strips sleeved on the edge of the sliding door to melt the ice and further open the sliding door.
[0038] In step 150, the detecting action and the heating action are repeatedly performed.
[0039] The detection action and the heating action are performed alternately. For example, after heating for 5 seconds, the rotation speed is detected to be greater than zero. If it is not greater than zero, it indicates that the ice has not melted enough, and heating is continued. If it is found that the rotation speed of the driving motor is not equal to zero or is greater than zero after several alternations, it indicates that the ice has melted to the extent that the sliding door can be opened normally, and the heating of the ice with the help of the heating strip is stopped.
[0040] In step 160 , when it is detected that the rotation speed is greater than zero, the heating is stopped and the electric sliding door of the vehicle is opened.
[0041] The speed of the driving motor is greater than zero, indicating that the sliding door is in the process of opening.
[0042] In some embodiments, a voice prompt system is also used to remind the driver and passengers that the sliding door is opened normally, thereby improving the driver and passengers' experience.
[0043] In the method for opening the electric sliding door of a car in the disclosed embodiment, the frozen electric sliding door can be opened normally even in severe cold weather, thereby improving the driving experience.
