It particularly helps to develop the present Chinese undergraduates’ imagination, practical abilities, team awareness, and hitech innovation capacity.

[2] Wang Chaoyi, Wang Yihuai. Design of Control System of Auto Tracking Car Based on Infrared Sensor [J]。 the paper focuses on layout of tracking circuit for the car and design ideas for the software. The experiment result proves that the designed intelligent car is stable in operation and good in tracking performance. Keywords: ARM Intelligent Tracking 1 、 Introduction In the 21st century, with development of science and technology, researches on intelligent car and its correlative techniques have bee the focus in this field. Aiming to enhance practical ability， innovation, and teamwork performance of college students across the country, the Education Department sponsored National Undergraduate Intelligent Car Contest. Based on the background, the paper introduces the design of multifunctional intelligent car controller on embedded platform, including design of hardware circuit and software implementation for key functional modules. Design of hardware By function and application, the controlling platform for the intelligent car is divided into several modules as shown below. Design of core module AT91SAM7S256 microprocessor produced by ATMEL has been adopted for the controller of the car, which a 32bit lowpower RISC microprocessor chip based on ARM7 TDMIS core, and embedded with 64KB SARM, 256KB highspeed Flash and JTAG port for downloading or debugging of the program. As the core ponent of the car, the microprocessor plays a key role in controlling all running statuses of the car. PWM generating module inside it can be change duty cycle of outputted square wave by programming, and thus change the voltage loaded on the DC motor, which is amplified to control the revolution speed of the motor. The ports PA0, PA1, PA2 and PA3 of the PWM module respectively control the DC motor and the steering motor to perform functions such as go forward, retreat and turn etc. Design of powe
