I ncluding the minimum system circuit, power management part, motor drive circuit, servo drive circuit, path recognition circuit and the geminate transistors circuit, the system takes the MC9S12XS128 SCM as its microcontroller. Besides , relative calculations of parameters are also given. In this a utomatic c arp arking g arage s ystem, the smart car is designed to drive to the assigned garage automatically from the entrance and to park in the storage accurately, though identifying information of roads, traffic lights and garages. Firstly, the system is used to deal with the information searched D camera, then to find the deviation between the position of the car and the central black line, and correct the car through a steering gear. In addition, the infrared tubes can be installed in front of the car to determine the locations of the empty parking spaces and the signal lights. Similarly, the directions of signal lights can be detected D camera as well to make the car drive in the garage correctly.
