基于单片机的智能电动车设计

AbstractIn the era of high-speed development of science and technology.Withthe popularization of AI Artificial Intelligence technology and driverlessdriving,the trend of automobile driving technology has gradually shown itsface.Now the listed cars (such as Tesla electric vehicle,Honda new energyvehicle,Toyota New Energy Vehicle)have begun to take a share in the AImarket.One of the most serious problems China is facing is the highincidence of traffic accidents,and the death rate of traffic accidents ranksfirst in the world.At present,the government and many business of the worldhave come to solve this problem.To improve the threshold of vehicle safetymonitoring,to introduce foreign car building technology,to improve thephysical stability of the car structure,to strengthen the strength of the carbody and so on,are all measures that we have taken,while artificialintelligence driving is the future of safe driving,with mature manual driving,computer reliable calculation will greatly reduce driving errors and thusreduce the incidence of traffic accidents.Of course,the Great Wall is notbuilt in one day,and safe driving is a long-term problem for all mankind.Itrequires not only the improvement of automobile safety coefficient,but alsothe improvement of policies,traffic management system and theimprovement of comprehensive quality of car owners.It is a longrevolutionary journey.This system takes AT89C51 as the main control core,and makes anintelligent car,aiming to explore the intelligent car.Design and manufactureintelligent electric vehicle.The components include battery pack,single chipmicrocomputer,motor with encoder,plastic tire,ultrasonic sensor,LEDdigital tube,acrylic plate,etc.Realization function:the car controls themotor through the single-chip microcomputer,and the car completes thefollowing actions in 30 seconds:forward,left,backward and right;thecontroller of the car should preset a good time,after the car stops,throughthe motor with code,calculate the number of turns of the motor rolling,so asto calculate the distance,and the LED digital tube shows the travel time andthe final travel distance.Complete all actions within the scheduled time.When the car is in front of and encounters obstacles,the ultrasonic sensor
