Based on the analysis of the measurement characteristics and uncertainty of ultrasonic sensor,a novel ultrasonic sensor model is introduced.In this model,the reliability of grid information in the sector region of ultrasonic sensor can be calculated using the D-S evidence theory,the obstacle position can be detected in the range of ultrasonic sensor.The simulation results indicate that the model is efficiency and applicability.
