Abstract
Systems and methods for the calibration of 3-axis accelerometers using vertical sample buffers in accordance embodiments of the invention are disclosed. In one embodiment, a telematics system includes a processor, an acceleration sensor, a velocity sensor, and a memory configured to store an acceleration alignment application, wherein the acceleration alignment application configures the processor to receive a velocity information sample using the velocity sensor, determine vehicular acceleration information along at least one vehicle axes using the velocity information sample, receive at least one acceleration sensor acceleration information sample using the acceleration sensor, determine a plurality of vertical vector samples using the vehicular acceleration information, calculate an average vertical vector sample using at least one of the vertical vector samples, and calibrate at least one of the vehicle axes to an acceleration sensor axis using the vehicular acceleration information, the acceleration sensor acceleration sample, and the average vertical vector sample.
