Abstract
Disclosed herein is a system and method of acquiring the bias of a yaw rate sensor for a vehicle. The method includes matching, by a processor, map information based on global positioning system (GPS) information and vehicle speed information and determining a curvature of a road. The method further includes calculating, by the processor, a map based yaw degree based on the curvature of the road using steering angle information and the vehicle speed information. Additionally, the method includes acquiring, by the processor, the bias of the yaw rate sensor by comparing a measured value of the yaw rate sensor with the map based yaw degree.

A method of acquiring a bias of a yaw rate sensor for a vehicle, comprising:
- matching, by a processor, map information based on global positioning system (GPS) information and vehicle speed information;
- determining, by the processor, a curvature of a road;
- calculating, by the processor, a map based yaw degree based on the curvature of the road using steering angle information and the vehicle speed information;
- and
- acquiring, by the processor, the bias of the yaw rate sensor by comparing a measured value of the yaw rate sensor with the map based yaw degree.
A system of acquiring a bias of a yaw rate sensor for a vehicle, comprising:
- a processor configured to:
- match map information based on global positioning system (GPS) information and vehicle speed information;
- determine a curvature of a road;
- calculate a map based yaw degree based on the curvature of the road using steering angle information and the vehicle speed information;
- and
- acquire the bias of the yaw rate sensor by comparing a measured value of the yaw rate sensor with the map based yaw degree.
A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
- program instructions that match map information based on global positioning system (GPS) information and vehicle speed information;
- program instructions that determine a curvature of a road;
- program instructions that calculate a map based yaw degree based on the curvature of the road using steering angle information and the vehicle speed information;
- and
- program instructions that acquire the bias of the yaw rate sensor by comparing a measured value of the yaw rate sensor with the map based yaw degree.
