Abstract
A method for determining the position in a vehicle of a first device in communication with a microprocessor may include receiving, at the microprocessor, a first set of inertial data from at least one sensor of the first device; receiving, at the microprocessor, a second set of inertial data from at least one sensor of a reference device disposed within the vehicle; and determining, using the microprocessor, the position of the first device in the vehicle by comparing the first set of inertial data with the second set of inertial data.
Claims20
A method for determining the position in a vehicle of a first device in communication with a microprocessor, the method comprising:
- receiving, at the microprocessor, a first set of inertial data from at least one sensor of the first device;
- receiving, at the microprocessor, a second set of inertial data from at least one sensor of a reference device disposed within the vehicle;
- and
- determining, using the microprocessor, the position of the first device in the vehicle based on at least one difference between the first set of inertial data and the second set of inertial data, wherein determining the position of the first device comprises detecting for the first device a relative lateral position with respect to the vehicle center;
- wherein the reference device in the vehicle is one of the following:
- a device fixed at a reference point in the vehicle;
- a device connected to an onboard diagnostics system;
- a component of the vehicle;
- a second device within the vehicle;
- or
- a second device at an unknown position.
A method for translating orientation-dependent sensor measurements from a device of unknown orientation inside a vehicle into a vehicle coordinate frame, the method comprising:
- receiving a first set of inertial data from at least one sensor of the first device;
- estimating a moving vector of the vehicle from the first set of inertial data;
- and
- using the moving vector to determine the sensor measurement along the axis of movement.
