Abstract: This vehicle control system comprises: a driving control section 1 that performs switching between autonomous driving and manual driving of a vehicle V; a seat 10 that can be changed to forms which are different during autonomous driving and during manual driving; and a seat control unit 2 that controls the operation of the seat 10 when changing the forms. If the seat 10 is in the form adopted during autonomous driving, the driving control unit 1 can perform control so that the switching from autonomous driving to manual driving of the vehicle V is not performed. Thus, it is possible to improve safety when switching from autonomous driving to manual driving.

Abstract: A vehicle seat (1) is provided with a cushion frame (5) that can be moved up and down by means of a link mechanism (6). To assist the upward movement of the cushion frame (5), a torsion bar (14) is disposed in a connection pipe (12) having both ends secured to a pair of left and right rear links (11, 11). A position holding member (24) holds the torsion bar (14) and is supported by the connection pipe (12), whereby the positional shift of the axis of the torsion bar (14) is suppressed. The position holding member (24) engages an extension portion (16) extending perpendicular to the shaft portion (15), and thus, does not rotate around the axis relative to the torsion bar (14). Therefore, in the position holding member (24), portions requiring reinforcement against a transverse force from the torsion bar (14) are limited a narrow range, and the position holding member (24) can be reduced in size and weight.
