A Study on Control Logic Design for Power Seat 2019-01-0466

The large luxury sedan seats have a maximum movement of 22 way, each of which offers wide moving ranges from 30mm to 260mm. Although the mechanism provides a wide range of adjustments to enhance passenger comfort performance, the seat’s operating range is the largest and widest out of all moving parts of the interior components, facing many constraints on its movement in the constrained interior space. In addition, the power seat is operated by a motor, which makes it difficult for users to determine the amount of adjustment, unlike the manual seat adjustment that allows users to decide the adjustment scope according to their power and feeling. IMS, one-touch mode, is also constrained by parameters such as indoor space package, user's lifestyle, etc. during function playback. In this regard, this paper aims to design the seat control logic to achieve the best seat comfort while satisfying each constraint. This paper discusses constraints of power seat movement through seat control logic and methods to devise robust design of control logic. The results of this study are as follows. - Increase robustness of power seat control logic - Provide optimal adjustments and comfort at each location - Offer differentiated custom control and seating modes for each seat - Improve customer satisfaction and quality by upgrading software In addition to the detailed specification of power seat control logic constraints, the design method for satisfying each constraint condition and the customized power seat control in each seat will be examined and actual application cases will be identified.
