Abstract
An approach is provided for determining vehicle speed. The approach, for example, involves determining sensor data from a magnetometer, an accelerometer, or a combination thereof associated with a vehicle. The approach also involves processing the sensor data to determine a rotational frequency of at least one tire of the vehicle. The approach further involves calculating a speed, a tire/wheel diameter, a safety condition, and/or a maintenance condition of the vehicle based on the rotational frequency and providing the speed, the tire/wheel diameter, the safety condition, and/or the maintenance condition as an output.
Claims20
A method comprising:
- determining, by a processor, sensor data from a magnetometer, an accelerometer, or a combination thereof associated with a vehicle;
- processing, by the processor, the sensor data to determine a rotational frequency of at least one tire of the vehicle;
- calculating, by the processor, a speed of the vehicle based on the rotational frequency;
- and
- providing, by the processor, the speed as an output.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
- determine sensor data from a magnetometer, an accelerometer, or a combination thereof associated with a vehicle;
- process the sensor data to determine a rotational frequency of at least one tire of the vehicle;
- calculate a diameter of the at least one tire or wheel of the vehicle based on the rotational frequency;
- and
- provide the diameter as an output.
A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to perform:
- determining sensor data from a magnetometer, an accelerometer, or a combination thereof associated with a vehicle;
- processing the sensor data to determine a rotational frequency of at least one tire of the vehicle;
- calculating a safety condition, a maintenance condition, or a combination thereof of the vehicle based on the rotational frequency;
- and
- providing the safety condition, the maintenance condition, or a combination thereof as an output.
