Multi-rate vehicle side slip angle estimation using low-cost GPS/IMU

This paper proposes a side slip angle estimation method using a low-cost Global Positioning System (GPS)/Inertial Measurement Unit (IMU). To estimate the side slip angle, we use the yaw rate of IMU and the course angle of GPS. Planar lateral vehicle model-based estimator was designed to integrate the yaw rate of IMU and course angle of GPS. The proposed method was validated via an experiment.
