Abstract
Systems and methods for low-latency calibration of the alignment of 3-axis accelerometers in accordance embodiments of the invention are disclosed. In one embodiment of the invention, 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 determine vehicular forward acceleration information and vehicular lateral acceleration information, calculate a lateral acceleration vector, a forward acceleration vector, and a vertical acceleration vector using a forward incline vector and a lateral incline vector determined using the vehicular forward acceleration information and vehicular lateral acceleration information.
