Nonlinear Observer for Vehicle Velocity with Friction and Road Bank Angle Adaptation – Validation and Comparison with an Extended Kalman Filter
نویسندگان
چکیده
Many active safety systems in automotive vehicles, for instance yaw stability systems such as ESC/ESP, depend on information about vehicle velocity, in particular lateral velocity or side-slip angle, to be able to function properly. However, the vehicle velocity is rarely measured directly due to issues of cost and reliability, and must therefore in general be inferred from other measurements, such as wheel speed, steering angle, yaw rate, and acceleration measurements.

Identification of an Autonomous Underwater Vehicle Dynamic Using Extended Kalman Filter with ARMA Noise Model
In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...

In designing the anti-lock braking system (ABS), some states and parameters of vehicle system such as road friction of coefficient and wheel slip should be estimated due to lack of cost effective and reliable sensors for direct measurement. Because of nonlinear characteristics of vehicle dynamics and tire forces, development of a nonlinear estimation algorithm is necessary. However, considerati...
متن کاملNonlinear observer for vehicle velocity estimation
A nonlinear observer for estimation of lateral and longitudinal velocity of automotive vehicles is proposed, based on acceleration and yaw rate measurements in addition to wheel speed and steering angle measurements. Stability of the observer is proved in the form of input-to-state stability of the observer error dynamics, under an assumption on the friction model. This assumption is treated wi...
متن کاملVehicle Roll and Road Bank Angles Estimation
Abstract: Driving safety can be enhanced by better understanding of risk situation, which can be achieved by the knowledge of vehicle dynamic states as well as the road geometry. Among the parameters of the road that have an influence on vehicle dynamics, one can find the bank angle, which can not however be measured by low cost onboard sensors. In this paper, a new method of road bank angle an...
متن کاملSliding Mode
We describe a nonlinear observer-based design for control of vehicle traction that is important in providing safety and obtaining desired longitudinal vehicle motion. First, a robust sliding mode controller is designed to maintain the wheel slip at any given value. Simulations show that longitudinal traction controller is capable of controlling the vehicle with parameter deviations and disturba...
