چکیده
This paper proposes an autonomous vehicle trajectory tracking system that fully considers road friction. When intelligent drives at high speed on roads with different friction coefficients, the difficulty of its control lies in fast and accurate identification coefficients. Therefore, improved strategy is designed based traditional recursive least squares (RLS), which utilized for coefficient. First, tire force slip rate required estimation coefficient by constructing dynamics model effective are calculated. In this paper, a variable forgetting factor (VFF-RLS) method proposed construction estimator. Second, identified results output to predictive controller (MPC) constructed as way improve angle constraints, realize vehicle. Finally, joint simulation test Carsim Matlab/Simulink show VFF-RLS estimator has outstanding performance.

Road Friction Coefficient Estimation For Vehicle Path Prediction
One of the most noticeable trends of the automotive industry in the 1990's is the emerging of active safety technologies. Instead of passive protection and crash worthiness, emphasis has been shifted toward accident prevention and damage reduction using active safety techniques. To develop effective active safety devices, it is necessary to estimate vehicle motions accurately, and reliable road...

متن کاملLADAR-Based Vehicle Tracking and Trajectory Estimation for Urban Driving
Safe mobility for unmanned ground vehicles requires reliable detection of other vehicles, along with precise estimates of their locations and trajectories. Here we describe the algorithms and system we have developed for accurate trajectory estimation of nearby vehicles using an onboard scanning LADAR. We introduce a variable-axis Ackerman steering model and compare this to an independent steer...
متن کاملEstimation of the Maximum Tire-Road Friction Coefficient
We develop and test a ‘‘slip-based’’ method to estimate the maximum available tire-road friction during braking. The method is based on the hypothesis that the low-slip, low-m parts of the slip curve used during normal driving can indicate the maximum tire-road friction coefficient, mmax . We find support for this hypothesis in the literature and through experiments. The friction estimation alg...
متن کاملVehicle Trajectory Estimation Based on Monocular Vision
This paper proposes a system to estimate the 3D position and velocity of vehicles, from images acquired with a monocular camera. Given image regions where vehicles are detected, Gaussian distributions are estimated detailing the most probable 3D road regions where vehicles lay. This is done by combining an assumed image formation model with the Unscented Transform mechanism. These distributions...
