Abstract
An approach is provided by a mobile information handling system that includes a processor, and a gyroscope, a gravity sensor, and a memory each accessible by the processor. The approach identifies, at the mobile device that is moving with a vehicle, when a rotation of the gyroscope is at a near-zero moment, and an acceleration, wherein the acceleration is detected as being on a plane that is near-perpendicular with a gravity sensed by the gravity sensor. Then the detection is made, the approach determines a direction of the vehicle as being parallel to a direction of the detected acceleration. The approach then aligns a coordinate system used in the mobile device based on the determined direction of the vehicle.
