Abstract

To provide an attitude estimation system for an automobile and an offset error calculation method for a three-axis acceleration sensor for correcting an error caused depending on the mounting attitude of an acceleration sensor with respect to an automobile, using a three-axis acceleration sensor, a Roll angle Roll_A and a Pitch angle Pitch_A are measured in a state where an automobile is parked with a forward orientation in a parking lot, where a Roll angle Roll_B and a Pitch angle Pitch_B are measured in a state where the automobile is parked with an opposite orientation in the parking lot, and the average of Roll_A and Roll_B is set as an offset error in the Roll direction, and the average of Pitch_A and Pitch_B is set as an offset error in the pitch direction.
