Method for determining optimal sitting posture of intelligent seat of shared automobile based on eye ellipse

Abstract

The invention discloses a method for determining the optimal sitting posture of an intelligent seat of a shared automobile based on an eye ellipse. The method comprises the following steps that 1, a camera detects the body size of a driver when the driver gets on the automobile; 2, whether the driver enters the automobile or not is judged; 3, a plurality of driver sitting posture arrangement schemes are generated according to a cab arrangement size and driver height; 4, safety check is performed on the generated various driver sitting posture arrangement schemes; 5, sitting postures passing the safety check are scored according to a unified evaluation standard, and the sitting posture with the highest score is selected as the optimal sitting posture; 6, a single chip microcomputer calls the optimal sitting posture, and a stepping motor driving circuit is controlled to adjust a driver seat to a position corresponding to the optimal sitting posture; 7, whether the automobile seat enters a manual adjustment state or not is judged by detecting whether a manual adjustment button is triggered or not; and 8, after a driving state is finished, the seat enters a reset state and automatically moves to the rearmost end position of a front-back adjustable stroke.

Description

technical field [0001] The invention relates to the technical field of automobile ergonomics, in particular to a method for determining an optimal sitting posture of a driver based on an eye ellipse, which is applied to an intelligent seat adjustment system of a shared automobile. Background technique [0002] During the driving process, the driver's joint angle and sitting posture are not only related to driving and riding comfort, but a good driving sitting posture can also ensure that the driver has a good vision and manipulation convenience, thereby ensuring driving safety. At present, the general standards related to the determination of the driver's sitting posture include SAE J1517-2011, SAE J941-2008, and ISO 4513. Through the experimental research on the layout tools such as eye ellipse and H point, the driver's seat position and eye position can be determined respectively. Point location prediction. [0003] Driving comfort and fatigue are related to the driving s...

Problems solved by technology

However, the seat adjustment results of this technical solution are based on the driver's feeling, and some drivers have non-standard sitting postures. At the same time, the operation steps are cumbersome and time-consuming, and there is little difference from the traditional electric seat adjustment, and the degree of intelligence is low.
