In the present embodiment, the user can set the door control mode by operating the center control of the automobile.
If the vehicle door main body is opened according to the expected vehicle door opening value, the expected vehicle door opening value needs to be converted into a motor rotating angle, and then the motor is controlled to open the vehicle door main body according to the motor rotating angle.
Specifically, the speed at which the door is opened in the present invention is determined based on the expected value of the door opening. In this embodiment, the maximum opening degree of the door inside handle is L, the stroke of the distance by which the user pulls the door inside handle is s (0 ≦ s ≦ L), and the maximum opening degree of the door is R ≦ 90 °, so that the door opening prediction period value q is q ═ s/L × 100%, and the target opening degree t of the door is t ═ q × R. If the expected value q of the opening degree of the vehicle door is greater than 0.1, the opening process of the vehicle door comprises three stages of acceleration, constant speed and deceleration, the opening speed of the vehicle door in the constant speed stage is V0, the rotating stroke of the motor from closing to fully opening of the vehicle door is S0, the total expected opening time is T0, the duration time of the acceleration stage and the duration time of the deceleration stage are both T1, and the opening speed of the vehicle door in the acceleration stage and the deceleration stage is obtained by looking up a table according to the size of the expected value q of the opening degree of the vehicle door. The opening speed V0 of the vehicle door in the constant speed stage is V0 ═ q × S0/(T0-T1). If the expected value q of the opening degree of the vehicle door is not more than 0.1, the opening process of the vehicle door only comprises a constant speed stage.

and if the distance between the vehicle door main body and the obstacle is larger than or equal to the first distance threshold value, unlocking the vehicle door and opening the vehicle door main body according to the expected value of the opening degree of the vehicle door.
That is, if the door controller judges that the distance is too small according to the distance signal before the motor performs the door opening action, the door opening action is not performed, the door body and the barrier are prevented from being rubbed and touched, and the central control of the automobile carries out related prompt on a user and waits for the user to input the expected door opening degree value again.
Further, the method for controlling the opening degree of the electric vehicle further comprises the step of judging whether to stop opening the door in the process of opening the vehicle door main body.
