A design of path recognition based on acceleration transducer has been proposed.This design uses the three-axis accelerometer MMA7260Q.It detect the acceleration signal when the smart car is moving.As the core of controller
Embedded SCM MC9S1212DG128B has been used.The acceleration signal is sampled and converted to digital data via the ADC of the microcontroller.Then the data are saved in EEPROM.So the problem of the smart car’s path analysis is resolved very well.
