Control panel for electric car system with Labview

Abstract

Generally, the basic control system for general electric car is driven by DC motor. The most electric cars use two motors to power driving wheels, so speed control of DC motor plays an important role. To control the speed of DC motor, we can only change the revolution of DC motor. This paper proposes the speed control for electric car by control panel with Labview software. The control panel consists of six small windows, which are speed display, gear shift display and control, battery status, button for speed change and main start. The change of the speed will be displayed and it will check and shift gear to the corresponding speed. In experiment, we connect the main controller card supported with Labview to DC motor, gear set and other electronic components. Finally, we compare the speed control by panel with the real speed. © 2011 Pushpa Publishing House.
