Apparatus for controlling speed of mobile object
First Claim
1. An obtainer for obtaining speed feeling of a driver of a movable object, the obtainer comprising:
- a gaze point setter that sets a gaze point of the driver of the mobile object;
a motion detector that detects relative motion of an environmental field around the mobile object with respect to the mobile object;
a divergent component calculator that;
projects the relative motion of the environmental field in a coordinate system, the coordinate system being formed by modeling a retina sphere of the driver of the mobile object, andcalculates each of divergent components of the projected relative motion of the environmental field radially expanding from the gaze point; and
a speed feeling calculator that calculates speed feeling of the driver based on the divergent components of the projected relative motion of the environmental field radially expanding from the gaze point calculated by the divergent component calculator.

Abstract
In an obtainer for obtaining speed feeling of a driver of a movable object, a gaze point setter sets a gaze point of the driver, and a motion detector detects relative motion of an environmental field around the mobile object with respect to the mobile object. A divergent component calculator projects the relative motion of the environmental field in a coordinate system. The coordinate system is formed by modeling a retina sphere of the driver of the mobile object. The divergent calculator calculates each of divergent components of the projected relative motion of the environmental field radially expanding from the gaze point. A speed feeling calculator calculates speed feeling of the driver based on the divergent components of the projected relative motion of the environmental field radially expanding from the gaze point calculated by the divergent component calculator.

3. A speed control apparatus for a mobile object, the apparatus comprising:
-
a gaze point setter that sets a gaze point of a driver of the mobile object; a motion detector that detects relative motion of an environmental field around the mobile object with respect to the mobile object; a divergent component calculator that; projects the relative motion of the environmental field in a coordinate system, the coordinate system being formed by modeling a retina sphere of the driver of the mobile object, and calculates each of divergent components of the projected relative motion of the environmental field radially expanding from the gaze point; a total calculator that calculates a total of at least a number of the divergent components of the projected relative motion of the environmental field, the at least the number of the divergent components being included in a predetermined area containing the gaze point; and a controller that controls the speed of the mobile object such that the total of the at least a number of the divergent components of the projected relative motion of the environmental field is substantially kept constant. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13)
