【文章內容簡介】 riving through various sensors Except some smart cars equipped with multiple outside sensors can fully perception of information and traffic facilities and to judge whether the vehicles and drivers in danger has the independent pathfinding navigation avoid bump no parking fees etc Function Effectively improve the safe transport of manipulation reduce the pilot fatigue improve passenger fort Of course battery electric vehicle is the key the electric car battery mainly has the use of leadacid batteries nickel cadmium battery the battery sodium sulfide sodium sulfide lithium battery the battery the battery the flywheel zinc air fuel cell and solar battery the battery In many kind of cells the fuel cell is by far the most want to solve the problem of energy shortage car Fuel cells have high pollution characteristics different from other battery the battery need not only external constantly supply of fuel and electricity can continuously steadily Fuel cell vehicles FCEV can be matched with the car engine performance and fuel economy and emission in the aspects of superior internalbustion vehicles ic car from ordinary consumers distance is still very far away only a few pAlong with the puter and electronic product constantly upgrading electric car open class in mature technology and perfected that drive more safe convenient and flexible fortable Now the electreople in bandwagon Electric cars with traditional to pete in the market the car Will was electric cars and intelligent car replaced This is the question that day after timing will e ABS GPS and various new 4WD 4WS electronic products and the modern era excellent performance auto tacit understanding is tiein bring us unparalleled precision driving fort and safety of driving The hardware and software of the intelligent vehicle are designed based on AVRThis system could set the route in advance The vehicle could municate with the PC vianRF401 and could run safely with the help of ultra sound detection and infrared measuring circuitNeural work self study is used to improve the intelligence of the vehicle The performance of servo systems will determine the property of the robot． Based on AVRseries MCUthe velocity servo system for driving motor is created in this paperincluding a discrete PIregulator which will work out a PWM control signal with applying the skill of integral separation． The velocities of motors will be controlled real － time with the speed sampling frequency set for 2KHz by using the AVR － GCC piler software development． Compared to the servo system development based on the 51 Series MCUthe system here has these advantages of simpler peripheral circuit and faster data processing ． The experiments demonstrate thatthe mobile robot runs stably and smoothly by the control of AVR unitsand that the design proposal especially benefits the development of intelligent mobile robotsalso can be widely used in the development of other smart devices and product lines． A new design of contest robot cont rol system based on AVR Atmega8 was put forward According to the character of contest robot the main cont rol unit motor drive unit sense detection unit and LCDdisplay unit wereintroduced Furthermore the servo driver system based on MCBL3006S the line t racker sensor system and the obstacle avoidance sensor system were presented in detail Finally the performance showsthat the cont rol system is open simple easy programming intelligent and efficiency Avoidance rules of intelligent vehicle obstacle are introducted Through the collection of infrared sensor formation the rules use diode D1 to launch and diode D2 to receive infrared signals Infrared transmitter signal without a dedicated circuit es directly from the MCU clock frequency which not only simplifie the circuit and debugging but also make the circuit stability and anti jamming capability greatly enhanced After the experimental verification the system runs reliably meet the design requirements A smart car control sys tem of the path informat ion identif ied based on CCD camera was introduced The hardware s truc ture and scheme were designed The contro l strategy of s teering mechanismwas presented T he smart car not only can identify the road prec isely but also have antinterference performance and small s teady state error This article designed smartcar systemincludes the aspects of the sensor information acquisition and processing motor drive control algorithm and control strategy etcUsing laser sensor to collect the road information which can feedback to the microcontroller control systemthen making analytical processing bined with the softwareWith velocity feedback and PID control algorithms to control steering engine and the speed of smartcarVerified by actual operation this method makes smartcar travel stably and reliablyand its average speed to reach 26m s and get a satisfied results By the aid o f the pro fessio na l know ledge of contr ol patter
