Abstract: A seat support mechanism (1) for a four-wheel vehicle driving simulator includes: a base (2) placed on a ground; a seat support base (5) with a seat (3) being fixed, a pair of cylinder type actuators (6) that connects the base (2) and the seat support base (5) at two front positions of the seat support base (5) to have a gap therebetween, and has both end portions as universal joints; a pair of hydraulic dampers (7) that connects the base (2) and the seat support base (5) at two back positions of the seat support base (5) to have a gap therebetween, and has both end portions as universal joints; and a ball joint (9) that connects the base (2) and the seat support base (5) at a central portion of the seat support base (5) to have a gap therebetween.
Abstract: An automatic-brake simulator (A) for a four-wheel vehicle is constituted by a body portion (a seat (11), a curved frame (12), a frame (13), a base (14), universal joints (15), and electric actuators (16)), an operation portion (a driving-operation device (2)), a control portion (a control-use computer (3), a sensor group (4), an orientation sensor (5), and a storage (6)), and an audiovisual portion (a head-mounted display (7), speakers (8), and a display (9)). When an automatic brake is activated, the seat on which an experiencing person (T) sits vibrates, and shifts and inclines forward, backward, leftward, rightward, upward, and downward in response to actuation of a group of the electric actuators while a composite VR moving image on the head-mounted display becomes still in a state in which a virtual obstacle is present immediately before the eyes.
Abstract: A seat support mechanism of a driving simulator for a four-wheeled automobile includes a lower frame (2) that is supported on a base (1) at one front point by a universal joint (6) and at two back points by cylinder actuators (5). The seat support mechanism further includes an upper frame (3) that is supported on the lower frame at one front point by a universal joint (8) and at two back points by cylinder actuators (7). The one front point and the two back points are arranged so as to form a substantially isosceles triangle that has the one front point as the apex, and a seat is mounted on and fixed to the upper frame.
