The invention discloses a vehicle seat system and an adjusting method of a vehicle seat back plate. The system comprises a seat, a back plate, an upper sliding block assembly, a lower sliding block assembly, an upper connecting rod, a lower connecting rod, a driving motor and a controller. The controller obtains the current position of the upper connecting rod and the current position of the lower connecting rod after the chair back deflects; setting a backboard target position, and obtaining an upper connecting rod target position and a lower connecting rod target position corresponding to the backboard target position; obtaining upper sliding block displacement according to the current position of the upper connecting rod and the target position of the upper connecting rod; obtaining lower sliding block displacement according to the lower connecting rod current position and the lower connecting rod target position; the target position of the backboard is adjusted, so that the total displacement of the sum of the upper sliding block displacement and the lower sliding block displacement is shortest; and the driving motor is controlled to enable the upper sliding block assembly, the lower sliding block assembly and the lower connecting rod to move according to the corresponding displacement and angle. The position of the back plate can be adjusted in a self-adaptive mode along with inclination of the seat, the occupied space is small during adjustment, and better comfort and convenience are achieved.
本申请公开了一种车辆座椅系统及车辆座椅背板的调节方法;系统包括:座椅、背板、上滑块总成、下滑块总成、上连杆、下连杆、驱动电机和控制器;控制器在椅背发生偏转后,获取上连杆当前位置和下连杆当前位置;设置背板目标位置,获得背板目标位置对应的上连杆目标位置和下连杆目标位置;根据上连杆当前位置和上连杆目标位置获得上滑块位移;根据下连杆当前位置和下连杆目标位置获得下滑块位移;调整背板目标位置,使上滑块位移与下滑块位移之和的总位移最短;控制驱动电机使上滑块总成、下滑块总成和下连杆按照对应的位移和角度运动。能够随着座椅倾斜自适应调节背板的位置,且调节时占用空间较小,具有更好的舒适性与便捷性。
