A method of transforming measurements from an accelerometer of a mobile phone to a reference frame of a vehicle in which the mobile phone is disposed includes classifying the measurements into those caused by the vehicle. Using these measurements, the method detects positive or negative acceleration events, determines a direction of an event with respect to the mobile phone, and determines a direction of the event with respect to the vehicle. Based on the two directions, the measurements are transformed to the reference frame of the vehicle.
