Systems and Methods for Low Latency 3-Axis Accelerometer Calibration

A telematics system, comprising:

• a processor;
• an acceleration sensor connected to the processor and configured to determine forward acceleration information along a forward axis, lateral acceleration information along a lateral axis, and vertical acceleration information along a vertical axis;
• a velocity sensor connected to the processor and configured to determine velocity information along a vehicular forward axis and heading information;
• and
• a memory connected to the processor and configured to store an acceleration alignment application;
• wherein the acceleration alignment application configures the processor to:
• determine vehicular forward acceleration information along the vehicular forward axis using the velocity information;
• determine vehicular lateral acceleration information using the velocity information and the heading information;
• calculate a lateral acceleration vector using the forward acceleration information, the lateral acceleration information, the vertical acceleration information, and the vehicular lateral acceleration information;
• calculate a forward acceleration vector using the lateral acceleration vector and the vehicular forward acceleration information;
• calculate a vertical acceleration vector using the lateral acceleration vector and the forward acceleration vector;
• compute lateral alignment information using the lateral acceleration vector, the forward acceleration information, the lateral acceleration information, and the vertical acceleration information;
• compute forward alignment information using the forward acceleration vector, the forward acceleration information, the lateral acceleration information, and the vertical acceleration information;
• and
• compute vertical alignment information using the vertical acceleration vector, the forward acceleration information, the lateral acceleration information, and the vertical acceleration information.
