All-electric intelligent anti-lock braking system (ABS) is a new technology to be developed and applied in the Electric Vehicles(EVs). It could completely replace the traditional mechanical brake as well as hybrid ABS system which is not suitable for electric vehicles. Thus it greatly improves the reaction speed, shorten the braking time, and is more easily to be integrated in the electric vehicle...
In this paper a model-based design and testing method focusing on the electric vehicle driveability aspect is proposed. The design approach is divided into two steps. The first step is the Model-in-the-Loop co-simulation coupling a vector-controlled electric drive modelled in MATLAB/Simulink to a planar forward-facing electric vehicle LMS Imagine. Lab Amesim model. The second step represents a mechanical-level...
So far, the authors' group have developed a pitching control method for electric vehicle (EV) based on the quick torque response of motors in order to improve the driving comfort. In this paper, a novel estimation method of braking torque is proposed to generate ideal vehicle acceleration for pitching control. The acceleration reference can be obtained from the estimated braking torque, motor torque,...
The paper presents the development of a generic simulation model on MATLAB/Simulink platform of an electric vehicle (EV). The components of the model such as the vehicle model, driver model, drivetrain model and the battery model are individually studied and modeling equations developed. The model accuracy is validated by comparison with the dynamometer test results on the motor. The model is employed...
Based on analyzing the driving system of motors in series, it indicates that the system simplifies the structure and realizes the effective self-action differential when the electric vehicle(EV) runs on the level road without any variety or at low velocity. When the EV runs on the variational road, especially the friction force is variant, the EV is unstable according to the character of the permanent-magnet...
A novel power assisted steering system was proposed in this paper, due to the independent driving characteristics of electric vehicle (EV) with four-wheel-independent-drive. The basic theory of differential drive torque assisted steering is discussed at first. After that, vehicle dynamics model with steering system was built in SIMULINK, and the control strategy for minimizing the difference between...
In this article is proposed an approach to study electric vehicles based on an experimental platform that adequately reproduces the behavior of electric vehicles by obtaining the correct equivalences between a vehicle and a test bench. In the first part the general dynamic equation of movement of a vehicle is stated, then how to obtain an equivalent dynamic equation for the test bench that represents...
