摘　　要：提出了一种基于加速度传感器的路径识别设计。该设计采用三轴加速度传感器MMA7260Q测量智能车在运动中的加速度信号,以嵌入式单片机MC9S12DG128B作为核心控制器,对加速度信号进行采样,A/D转换,再将特征数据存储在EEPROM中。很好地解决了智能车运动路径分析的问题。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.
