| Abstract: | A smart car system which takes laeser seneors to obtain lane information was proposed.The hardware includes the circuit of MCU system,mainboard,motor driving,sensors module and speed measuring.The system uses MC9S08AC16 as the core,low-cost infrared sensor to detect speed and bipolar circuit driving the motor,lasers of 14 emissions and 7 receipts detect the track,motor drive with "H" type bipolar drive circuit.The method of enumeration and table look-up to control steering gear is applied,and this arithmetic is suitable for 8 bit MCU.Bang-bang and P controlalgorithm are taken to control speed. |
