ELECTRIC VEHICLE AND METHOD FOR CONTROLLING THE SAME
First Claim
1. An electric vehicle comprising:
- a body portion;
an operating section that detects an operating direction of an inputted operation;
an obstacle sensor that detects obstacles existing in a vicinity of the body portion;
an obstacle determination section that forms a search region extending from the body portion in the operating direction and determines an obstacle existing in the search region among obstacles detected by the obstacle sensor, as the obstacle to be avoided; and
a control section that controls a movement of the body portion so that the body portion avoids the obstacle to be avoided, determined by the obstacle determination section.

Abstract
An electric wheelchair includes a body portion, an operating section to detect an operation by an operator, an obstacle sensor to detect an obstacle existing in the vicinity of the body portion, an obstacle determination section to form a search region extending from the body portion in an operating direction, and to determine an obstacle existing in the search region, as the obstacle to be avoided, a virtual repulsive force calculation section to calculate a virtual repulsive force to move the body portion away from the obstacle determined by the obstacle determination section, a resultant force calculation section to calculate a resultant force composed of an operating force and the virtual repulsive force, and a control section to control a movement of the body portion so that the body portion is moved in a direction of the resultant force.

20. A method for controlling an electric vehicle having an obstacle sensor and an operating section, comprising:
-
detecting a periphery of a body portion by the obstacle sensor; detecting an operating direction of an operation inputted to the operating section by the operating section; forming a search region extending from the body portion in the operating direction by an obstacle determination section, and determining an obstacle existing in the search region among obstacles detected by the obstacle sensor, as the obstacle to be avoided, by the obstacle determination section; and controlling a movement of the body portion by a control section so that the body portion avoid the obstacle when it is determined that there is the obstacle in the search region by the obstacle determination section in determining the obstacle.
