Abstract
Official abstract text for this publication.
A method, device and system for a method, device, and system for automatically adjusting driver-related in-vehicle equipment, the method including the steps of: acquiring a driver's height from a detection device of a vehicle; determining preset values of additional body parameters of the driver based on the driver's height and calculating a position for entry using the driver's height and the preset values of the additional body parameters of the driver; and adjusting the equipment including a driver's seat to the position for entry so as to facilitate the driver to enter the vehicle and sit on the seat.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for automatically adjusting driver-related in-vehicle equipment, the method comprising the steps of: acquiring a height of a driver from a first detection device of a vehicle; determining preset values of additional body parameters of the driver based on the driver's height and calculating a position for entry using the driver's height and the preset values of the additional body parameters of the driver; adjusting the equipment comprising a driver's seat to the position for entry so as to facilitate the driver to enter the vehicle and sit on the seat; acquiring updated values of the additional body parameters of the driver sitting on the seat from a second detection device of the vehicle and calculating a position for driving using the driver's height and the updated values of the additional body parameters of the driver; and adjusting the seat from the position for entry to the position for driving so as to optimize a driving posture of the driver sitting on the seat, wherein the step of determining preset values of additional body parameters of the driver based on the driver's height comprises: determining each of the preset values of the additional body parameters of the driver by multiplying the driver's height with a corresponding first proportionality factor, each corresponding first proportionality factor being derived from and greater than a corresponding second proportionality factor that is obtained from ergonomic data for representing a physical proportion of each of the additional body parameters of the driver to the driver's height, such that each of the preset values of the additional body parameters of the driver is greater than the corresponding updated value of the additional body parameters of the driver, and wherein the additional body parameters of the driver comprises the driver's torso length and the driver's head length, and both in the step of calculating a position for entry and in the step of calculating a position for driving, a formula below is used to calculate a height from an intersection point of a seat cushion and a backrest to a floor of the vehicle as a first adjustment parameter for the position for entry and a first adjustment parameter for the position for driving: h ′ = { h ′ = A × h driver - l upper × cos θ ′ - l head + B , others s 0 - l upper × cos θ ′ - l head , when h ′ < s 0 - l upper × cos θ ′ - l head l 0 - m 0 - l upper × cos θ ′ - l head , when h ′ > l 0 - m 0 - l upper × cos
