Study on Velocity Estimation for Four-Wheel Independent Drive Electric Vehicle by UKF

2013 Fifth International Conference on Measuring Technology and Mechatronics Automation, 2013
The four wheel torque is easy to get in the four-wheel i ndependent drive electric vehicle and the vehicle velocity estimation was studied by Unscented Kalman Filter (UKF) in this paper. The velocity estimation algorithm made use of the longitudinal acceleration, lateral acceleration and yaw rate signals measured by low cost sensors.

Estimation of road adhesion coefficient for four-wheel independent drive electric vehicle

2020 5th International Conference on Mechanical, Control and Computer Engineering (ICMCCE), 2020
In order to improve the stability of the vehicle during control process, it is necessary to estimate vehicle state parameters. One of the most important parameters is the road adhesion coefficient. In this paper, Dugoff tire model, seven-degree-of-freedom (7-DOF) vehicle model and adhesion coefficient observer based on unscented Kalman filter (UKF ...

A Novel Tyre Force Distribution Method for Four-Wheel Independent Driving Vehicles

Applied Mechanics and Materials, 2014
This paper discusses an optimal algorithm for distributing tyre force by an analytical multiplier penalty function method with which the maneuverability and stability of the four-wheel independent driving vehicles can be improved. Based on hierarchical method, the controller is divided into the upper level and lower level one.

Lateral stabilization of a four wheel independent drive electric vehicle on slippery roads

Mechatronics, 2015
Abstract In this paper, a new controller is proposed for lateral stabilization of four wheel independent drive electric vehicles without mechanical differential. The proposed controller has three levels including high, medium and low control levels. Desired vehicle dynamics such as reference longitudinal speed and reference yaw rate are determined by
