Vehicle dynamics have very complex characteristic and nonlinear behaviour. Vehicle dynamics are decomposed of many internal and external components which influence vehicle stability. External components come from environment such as wind forces, surface coarse of road, lane bend or sudden maneuver, which will change the value of vehicle stability parameters, i.e. yaw rate and sideslip. Both are influenced...
This paper presents sensorless control of Permanent Magnet Synchronous Motor (PMSM). In the sensorless control method, the stator current is measured to estimate the speed of the motor. When PMSM sensorless control is used in an electric vehicle, sometimes it causes another problem. When the motor is running in steady state and the motor is suddenly given a large load that has reverse torque direction,...
The development of electric vehicle is now growing rapidly. Demands to deliver a reliable and easy to drive in motor control causes Brushless Direct Current (BLDC) motor becomes a potential candidate. A BLDC motor drive is a potential option for an electric vehicle since it has a high reliability, simple design, and ability to work at high rotation per minute (RPM). This paper discussed the Permanent...
Charger is an important part in e-car. For a massive number of e-cars in the future, battery charger should have characteristics of high efficiency, rapid charging capability, portability, low-cost and compatible with the national standar electricity. In order to cover thus five parameters, the battery charger design should be transformerless, employing buck swith converting method, and having a microprocessor...
