Abstract:
An autonomous vehicle includes: a first sensor which obtains environmental information on surrounding environment of the autonomous vehicle; and a control unit which controls a drive unit based on a self position. The control unit includes: a first estimation unit which calculates a first estimate value indicating an estimated self position, by estimation using a probabilistic method based on the environmental information; and a second estimation unit which calculates a second estimate value indicating an estimated self position, by estimation using a matching method based on the environmental information, and the control unit changes, according to the first estimate value, a second estimate range for the calculating of the second estimate value by the second estimation unit, and controls the drive unit using the second estimate value as the self position.
