Description

Adjustment method of seat in vehicle, parking method and related equipment Technical Field The present application relates to the field of vehicles, and in particular, to a method for adjusting a seat in a vehicle, a parking method, and related devices. Background As the economic level increases, the level of intelligentization of the vehicle also increases. At present, the adjustment links of the seats in the vehicles mostly adopt a manual adjustment mode, namely, the seats are required to be manually adjusted by users. However, in the process of manually adjusting the seat, the user is often required to adjust the seat repeatedly, and the adjustment process of the seat is complicated, so a scheme capable of automatically adjusting the seat in the vehicle is needed to be introduced. Disclosure of Invention The application provides a seat adjusting method, a parking method and related equipment in a vehicle, wherein the position relation between a first point and a seat where a user is located is preset, so that the distance between eyes of the user and the first point can represent size information of the body of the user, and the seat adjusting information is determined according to the distance between the eyes of the user and the first point in the vehicle, thereby being beneficial to improving the fit degree between the adjusted seat and the body size of the user. In order to solve the technical problems, the application provides the following technical scheme: In a first aspect, the present application provides a method for adjusting a seat in a vehicle, which may be used in a vehicle field, where the vehicle obtains a first position of an eye of a user in the vehicle and a position of a first point in the vehicle, where a positional relationship between the first point and the seat where the user is located is preset, that is, a position of the first point corresponding to the target user is determined based on the position of the seat where the target user is located, where the first point may be a point of the preset position on the seat where the target user is located, or the first point may be a point obtained by shifting a point of a certain preset position on the seat where the target user is located. The vehicle determines a first value of the distance between the eyes of the user and the first point according to the first position and the position of the first point, determines adjustment information of the seat according to the first value, and executes adjustment operation on the seat according to the adjustment information of the seat. In the implementation manner, according to the value parameter of the distance between the eyes of the user and the first point in the vehicle, the adjustment information of the seat is determined, and the adjustment operation is automatically carried out on the seat according to the adjustment information of the seat, namely, a scheme for automatically adjusting the seat in the vehicle is provided; in addition, since the positional relationship between the first point and the seat in which the user is located is preset, the distance between the eyes of the user and the first point can represent the size information of the body of the user, and the adjustment information of the seat is determined according to the distance between the eyes of the user and the first point in the vehicle, it is advantageous to improve the degree of adaptation between the adjusted seat and the body size of the user. Optionally, the first point represents a position of the coccyx of the user when sitting in the seat, and the first value represents a sitting position of the user. For example, "the position of the coccyx of the target user while sitting on the seat" can also be understood as "the connection point of the human trunk and the thighs of the target user", that is, the crotch point (hippoint) of the target user. The position of the first point is calculated based on movement parameters of the seat, the movement parameters of the seat comprise movement parameters of the current position of the seat relative to a preset position of the seat, the movement parameters can comprise first movement parameters and/or second movement parameters, the first movement parameters indicate the movement distance of the seat where the target user is located in the longitudinal direction of the vehicle, and the second movement parameters indicate the movement distance of the seat where the target user is located in the vertical direction of the vehicle body floor. The first point may be a point at a preset position on the seat where the target user is located, or the first point may be a point obtained by shifting a point at a certain preset position on the seat where the target user is located. Illustratively, the first point may be a midpoint of a fold line between the seat back and the seat cushion of the seat in which the target user is located. Or the first point may be a point obtai
