Detecting Mount Angle of Mobile Device in Vehicle Using Motion Sensors
First Claim
Patent Images
1. A method comprising:
- obtaining motion data from a motion sensor of a mobile device mounted to a vehicle, where the motion data is obtained while the vehicle is moving;
obtaining a subset of the motion data obtained while the vehicle was not turning and the mobile device was not rotating;
obtaining a motion vector from the subset of motion data; and
obtaining a mounting angle from the motion vector, where the method is performed by one or more hardware processors.

Abstract
Motion sensors of a mobile device mounted to a vehicle are used to detect a mount angle of the mobile device. The motion sensors are used to determine whether the vehicle is accelerating or de-accelerating, whether the vehicle is turning and whether the mount angle of the mobile device is rotating. The mount angle of the mobile device is obtained from data output from the motion sensors and can be used to correct a compass heading. Data from the motion sensors that are obtained while the vehicle is turning or the mobile device is rotating are not used to obtain the mount angle.
