Method and system for adjusting vehicle seat Technical Field The application relates to the technical field of adjustment of vehicle seats, in particular to an adjustment method and an adjustment system of a vehicle seat. Background With the development of automobile technology, more and more manufacturers define more scene functions in the interior cabin of a seat. For example, enabling car seats to adjust based on user needs to make the seats more fit the human body to promote user experience. In the prior art, a vehicle seat provides a comfort mode, and when a user wants to adjust the seat to enable the seat to be more fit with own needs, the vehicle can control the seat to finish the adjustment of the backrest to fall down and the leg rest to be lifted by triggering a key started, so that the user can lie on the seat more comfortably. In this way, since the backrest lies flat, the restraint function of the safety belt on the human body can be disabled, the safety belt is very unsafe to use in the driving process, and only one seat adjustment type is too single to meet different requirements of users on seat adjustment. In addition, the existing vehicle seat also provides a back and waist massage mode of a partially fixed mode, and when a user wants to use, the user can massage the vehicle seat by controlling the buttons to open the massage mode. In this way, the seat adjustment type is limited, and the requirements of users with different body types and different sitting postures on the seat adjustment cannot be met. Therefore, the seat adjusting method provided by the prior art has the problems that the seat adjusting type is limited, and the seat adjusting requirements of different users cannot be met.
