It is to be understood that the position of the vehicle seat relative to the pedal is adjustable, and that the user can adjust the position of the vehicle seat, and thus the distance between the vehicle seat and the pedal, when the user is seated on the vehicle seat, to make the driving operation or ride more comfortable, so that the first positional relationship information may be dynamic, which changes as the adjustment of the vehicle seat by the user changes.
It can be understood that the pedal can be an accelerator pedal or a brake pedal, the specific type of the pedal is not applied and is not limited, the position relation between the accelerator pedal and the brake pedal relative to the vehicle is fixed, and the first position relation information between the vehicle seat and the pedal can be obtained only by arranging one displacement sensor.
Step 102: reference point position information of the vehicle seat is acquired based on the first position relationship information. It is to be understood that the first positional relationship information may be obtained based on a position of the vehicle seat after the position of the vehicle seat is adjusted by the user, and thus the first positional relationship information may represent a posture of the user, for example, the higher the height of the user, the larger the distance between the vehicle seat and the pedal, and the smaller the height of the user, the smaller the distance between the vehicle seat and the pedal, and thus the reference position information of the vehicle seat may be determined based on the first positional relationship information, and the reference position information may represent a shortest distance between a center point in a height direction of buttocks of the user and a seat surface of the vehicle seat when the user is seated on the vehicle seat.
Step 103: inclination angle information of a backrest of a vehicle seat is acquired. It will be appreciated that the inclination information of the backrest may be indicative of the sitting posture of the user.
Step 104: adjusting a position of the headrest relative to the backrest based on the reference point position information and the tilt angle information of the backrest. The position of the headrest is adjusted based on the reference point position information and the inclination angle information of the backrest, so that the position of the headrest is adapted to the posture and the sitting posture of the user, the setting position of the headrest is more appropriate, and the comfort level of the user can be improved. It will be appreciated that adjusting the position of the headrest may include adjusting the effective height of the headrest and the tilt angle of the headrest.
The control method of the vehicle provided by the embodiment of the application comprises the steps of firstly obtaining a first position relation between a seat and a pedal of the vehicle, representing the posture of a user sitting on the seat of the vehicle through the first position relation, then determining reference point position information based on the first position relation, enabling the reference point position information to be adaptive to the posture of the user, then obtaining inclination angle information of a backrest, enabling the inclination angle information of the backrest to represent the sitting posture of the user, finally adjusting the position of a headrest by combining the reference point position information and the inclination angle information of the backrest, enabling the position of the headrest to be adaptive to the posture and the sitting posture of the user, enabling the supporting effect of the headrest to be better, effectively supporting the head of the user, improving the comfort level of the user and improving user experience.

After the reference datum plane is defined, because the rotation center of the pedal is fixed, under the condition that the first position relation information of the vehicle seat is not changed, the first distance between the reference datum plane and the rotation center is fixed, the vertical distance between the reference point position information and the rotation center can be obtained by utilizing a trigonometric function based on the first distance, the second distance and the inclination angle information of the pedal, the vertical distance is the reference vertical distance, and the reference point position information can be obtained on the reference datum plane based on the reference vertical distance.
