The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of single item(s) or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", wherein a, b, c may be single or plural.
It is further noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in Random Access Memory (RAM), memory, Read Only Memory (ROM), electrically programmable ROM, electrically erasable programmable ROM, registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application.

the second driving unit is used for selecting a third speed parameter corresponding to the environment temperature and the parking gradient from a speed parameter set when the judgment result of the first judging unit is that the first preset condition is not met, and driving the electric tail gate to be opened or closed by using the third speed parameter; the speed parameter set comprises at least one speed parameter; the speed parameter has a corresponding relationship with the ambient temperature and the grade;
a second judging unit, configured to judge whether the ambient temperature and the parking gradient satisfy a second preset condition when the judgment result of the first judging unit is that the first preset condition is not satisfied; the second preset condition comprises a second preset temperature range and a second preset parking gradient range;
the third driving unit is used for acquiring a second speed parameter when the judgment result of the second judging unit meets the second preset condition, and driving the electric tail gate to be opened or closed by using the second speed parameter;
and the fourth driving unit is used for selecting a third speed parameter corresponding to the ambient temperature and the parking gradient from a speed parameter set when the judgment result of the second judging unit is that the second preset condition is not met, and driving the electric tailgate to be opened or closed by using the third speed parameter.
6. The apparatus according to claim 5, wherein the first determining unit specifically includes:
the first judgment subunit is used for judging whether the environment temperature is within the first preset temperature range;
and the second judgment subunit is used for judging whether the parking gradient is within the first preset gradient range.
