An onboard device includes a first learning unit that obtains gravity direction information caused by gravity by learning raw sensor information sensed by a sensor while the vehicle is not accelerated, a second learning unit that obtains travel direction information of the vehicle by learning the raw sensor information sensed by the sensor while the vehicle is accelerated; and a calculating unit that calculates an orientation conversion parameter for converting the raw information into the normalized information using the gravity direction information and the travel direction information. The raw sensor information is the acceleration information actually sensed by the sensor when the onboard device is installed in an arbitrary orientation in the vehicle, and the normalized sensor information is equivalent to the acceleration information that would be sensed by the sensor when the onboard device is installed in the vehicle with a specified orientation.
