Demands for vehicular systems with greater user support are increasing rapidly. The safety driving support system using a driving sound source has been investigated. As one piece of environmental traffic information, the information of approaching vehicles is important to secure driver safety. The papers to detect the approaching vehicles and to estimate the direction of the approaching vehicles have been reported. However, there is few research to estimate the time when the approaching vehicle arrives at the intersection. It is important to examine the estimation accuracy of the arrival time information from a viewpoint of the traffic accident prevention. This paper describes a basic technique of the support system which estimates the arrival time and the vehicle speed from the vehicle sound. This method applies a beamforming to control the direction of the sound in order to emphasize the vehicle sound captured by the 4-microphone array. Moreover, the arrival time and the vehicle speed are estimated using the support vector machine with the spectrum of vehicle sounds as input data. The feasibility of the arrival time and the vehicle speed estimation using vehicle sounds is confirmed in this paper. |
