PROBLEM TO BE SOLVED: To evaluate comfort with high precision in light of a riding condition of an occupant. SOLUTION: A physical volume showing a volume of a space around a seat in a cabin is calculated (102), and a visual volume showing a volume of a space in a vision of an occupant seated on a seat is calculated (104). A comfort value in a riding time t is calculated based on a comfort evaluation function Cs(t) defined according to a physical volume Vp(m<SP>3</SP>), a visual volume Vv(m<SP>3</SP>) and the riding time t of the occupant (106), so as to evaluate comfort in the cabin. The vision of the visual volume is made smaller as a vehicle speed gets higher, so that the visual volume is defined according to the vehicle speed. Also, Formula 10 is preferable as the comfort evaluation function Cs(t). In the formula, B, A' and B' are coefficients (1/m<SP>3</SP>), and C and C' are constants. COPYRIGHT: (C)2008,JPO&INPIT
