Abstract : The intelligent automobile is a new vehicle during this century. It can be carried out to keep away
from barriers ahead automatically , can navigate to lead the way automatically in the unfamiliar region , and
even to drive automatically. This paper introduces the working principle and design method of embedded sys
tem based on C8051F005. The system circuit is given and its working process is discussed. The main working
flow chart and design thought are presented also. The hardware circuit mainly includes measuring the distance
with ultrasonic wave circuit , and photo electricity detecting circuit.
Key words : embedded system ; ultrasonic wave ; phototransistor ; unpiloted vehicle
