Abstract: The seat waist support, namely lumbar, is mainly used in the early days to reduce the fatigue caused by sedentary, but with the development of the automobile industry for more than 100 years, the phenomenon of sitting for a long time has gradually appeared on the drivers. In order to relieve the fatigue in long-distance driving and improve their comfort and safety, the demand for adjustable seat backrest is on the rise. Based on the pressure sensors, the paper proposes and optimizes the control strategy of lumbar recall under the memory-recall mode of the auto seat, which makes the lumbar recall with high precision, without noise, in a short time and solves the engineering problem of lumbar reset due to the limitation of hardware structure.
