Lower structure of driver's compartment and method for determining pedal slant angles

A method for determining pedal slant angles of pedals of plural kinds of vehicle which are respectively equipped with a lower structure of a driver's compartment of a vehicle and have different levels of a sitting point of a driver's seat,

• wherein said lower structure of a driver's compartment of a vehicle comprises:
• an acceleration pedal to be pressed by an operational foot of a driver seated in the driver's seat, the acceleration pedal having a pressing face which is to be pressed by the operational foot and formed to slant such that a front portion thereof is positioned at a higher level than a rear portion thereof;
• a brake pedal to be pressed by the operational foot of the driver, the brake pedal having a pressing face which is to be pressed by the operational foot and formed to slant such that a front portion thereof is positioned at a higher level than a rear portion thereof;
• and
• a floor portion on which a heel portion of the operational foot of the driver is placed,
• wherein said pressing face of the acceleration pedal is located in front of said pressing face of the brake pedal, and a slant angle of the pressing face of the acceleration pedal relative to a horizontal face is different from a slant angle of the pressing face of the brake pedal relative to the horizontal face in a side view,
• said acceleration and brake pedals are comprised of a hanging type of pedal in which an upper end thereof is pivotally supported such that the pedal swings around the upper end,
• a slant angle, relative to the horizontal face, of an imaginary tangential line of said pressing face of the acceleration pedal which passes through a specified heel-placing point on said floor portion which is located at the center between the acceleration pedal and the brake pedal in a vehicle width direction is set to be smaller than a slant angle, relative to the horizontal face, of an imaginary tangential line of said pressing face of the brake pedal which passes through said specified heel-placing point on the floor portion in the side view, and
• in said method for determining pedal slant angles of pedals, the respective pedal slant angles of the acceleration and brake pedals of the plural kinds of vehicle are set such that said respective slant angles, relative to the horizontal face, of the imaginary tangential lines of the acceleration and brake pedals of the vehicle having a higher level of the sitting point of the driver's seat from the floor portion are relatively small compared to said respective slant angles, relative to the horizontal face, of the acceleration and brake pedals of the vehicle having a lower level of the sitting point of the driver's seat from the floor portion.

• said acceleration pedal is comprised of an organ type of pedal in which a lower end thereof is pivotally supported such that the pedal swings around the lower upper end, and said pressing face of the acceleration pedal is formed in a substantially flat shape,
• said brake pedal is comprised of a hanging type of pedal in which an upper end thereof is pivotally supported such that the pedal swings around the upper end,
• said slant angle of the pressing face of the acceleration pedal relative to the horizontal face is set to be greater than a slant angle, relative to the horizontal face, of an imaginary tangential line of said pressing face of the brake pedal which passes through a specified heel-placing point on the floor portion which is located at the center between the acceleration pedal and the brake pedal in a vehicle width direction in the side view, and
