1. An autonomous vehicle autonomously traveling in a work area for operation, comprising:
- a body;
a travel unit for moving said vehicle;
a distance measurement unit for measuring the distance from said body to a wall; and
a travel control unit for controlling said travel unit to determine said work area depending upon said distance output from said distance measurement unit at the start of operation and to move said body within said determined work area.

Abstract
An autonomous vehicle which permits a work area to be set without requiring the operator to input a numerical value includes a body, a travel unit for moving said body, a distance measurement unit for measuring the distance from the body to a wall, and a travel control unit for determining a work area depending upon the distance output from the distance measurement unit at the start of operation and controlling the travel unit to travel the body within the determined work area. Note that a method of controlling the traveling of such an autonomous vehicle is claimed as well.

14. A method of controlling the traveling of an autonomous vehicle, comprising:
-
a first step of measuring the distance from said autonomous vehicle to an obstacle; a second step of comparing said distance measured in said first step and a first prescribed distance; a third step of controlling said autonomous vehicle to travel such that the distance from said autonomous vehicle to said obstacle is equal to said distance measured in said first step, if said distance measured in said first step is larger than said first prescribed distance, and a fourth step of controlling said autonomous vehicle to travel such that said distance from said autonomous vehicle to said obstacle is equal to a second prescribed distance smaller than said first prescribed distance, if said distance measured in said first step is smaller than said first prescribed distance.

15. A method of controlling the traveling of an autonomous vehicle, comprising:
-
a first step of measuring the distance from said autonomous vehicle to an obstacle; a second step of comparing said distance measured in said first step and a first prescribed distance; a third step of controlling said autonomous vehicle to travel within a work area separated from said obstacle by said distance measured in said first step, if said distance measured in said first step is larger than said first prescribed distance; and a fourth step of controlling said autonomous vehicle to travel within said work area separated from said obstacle by a second prescribed distance smaller than said first prescribed distance, if said distance measured in said first step is smaller than said first prescribed distance.
