The Research Of The Control System Of Intelligent Car

Intelligent electric car not only can satisfy the elder’s indoor and outdooractivities, and also can be applied to medical rehabilitation training for the disabled.In this paper, I use the embedded intelligent technology to design the intelligentwalking vehicle control system which has high performance, low power consumption,simple operation and so on. The work what I finished is as follows：1. Hardware design. On this hand intelligent car consists of S3C2440coremotherboard, power supply and conversion module, the extension interface circuit,USB camera image acquisition module, GPS global positioning module and GPRScommunication module and so on.2. Software design. Intelligent car has the USB interface camera equipment andGPS global positioning and GPRS communication equipment driver, being able tocomplete the video image acquisition function and the global positioning function ofcommunication.3. JPEG compression algorithm. For the image in the network transmission withslow and low accuracy of global positioning system problems, so I use JPEG imagecompression and double difference single point positioning algorithm to achievequality improvement of the image.Designed with ARM9S3C2440in series as the core of intelligent car, intelligentcar has functions of road surveying and global positioning communication etc, furtherperfecting the special needs of the elderly activities, what’s more walking vehiclecontrol system has been finished the function test in production of electric car, and thesystem has good portability and can be used in similar products.
