چکیده

This paper proposes a cost-effective method to estimate the vehicle sideslip angle on various frictional surfaces on banked roads. This paper demonstrates that the vehicle sideslip can be estimated by combining measurements of Global Positioning System (GPS), Inertial Measurement Unit (IMU), and a magnetometer in the Kalman filter framework. Among all the measurements, the magnetometer is the most vulnerable to exogenous disturbances. To reject them, a stochastic filter is designed and integrated into the Kalman filter framework. Significant delays in GPS measurements are addressed by “measurement shifting”. The performance and accuracy of the proposed method are verified by comprehensive simulations and experiments.

Vehicle Sideslip Angle Estimation Using Two Single-antenna Gps Receivers

Knowing vehicle sideslip angle accurately is critical for active safety systems such as Electronic Stability Control (ESC). Vehicle sideslip angle can be measured through optical speed sensors, or dual-antenna GPS. These measurement systems are costly (~$5k to $100k), which prohibits wide adoption of such systems. This paper demonstrates that the vehicle sideslip angle can be estimated in real-...

State and Parameter Estimation for Vehicle Dynamics Control Using Gps

Many types of vehicle control systems can conceivably be developed to help drivers maintain stability, avoid roll-over, and customize handling characteristics. A lack of state and parameter information, however, presents a major obstacle. This dissertation presents state and parameter estimation methods using the Global Positioning System (GPS) for vehicle dynamics control. It begins by explain...

Vehicle sideslip angle measurement based on sensor data fusion using an integrated ANFIS and an Unscented Kalman Filter algorithm

Most existing ESC (Electronic Stability Control) systems rely on the measurement of both yaw rate and sideslip angle. However, one of the main issues is that the sideslip angle cannot be measured directly because the sensors are too expensive. For this reason, sideslip angle estimation has been widely discussed in the relevant literature. The modeling of sideslip angle is complex due to the non...

Integrating Inertial Sensors with GPS for Vehicle Dynamics Control

ABSTRACT This paper demonstrates a method of estimating several key vehicle states – sideslip angle, longitudinal velocity, roll and grade – by combining automotive grade inertial sensors with a Global Positioning System (GPS) receiver. Kinematic Kalman filters that are independent of uncertain vehicle parameters integrate the inertial sensors with GPS to provide high update estimates of the ve...
