PURPOSE:To reduce an accident by providing a drive circuit for driving a sounding device by fetching a signal from a luminous energy arithmetic part and a signal from a vehicle speed detecting part, so as to aurally inform a walker of approach. CONSTITUTION:A luminous energy detector 6 is mounted on a roof part or the like with a relatively fine view in a body of an electric vehicle. A luminous energy arithmetic part 7 performs an arithmetic process based on a signal from the luminous energy detector 6. A sounding device 8 is mounted on the vehicle so as to propagate a sound in a forward direction of the vehicle. In a vehicle speed detecting part 9, a speed of the vehicle is detected, and in a sounding part 10, a signal of the vehicle speed detecting part 9 is fetched to generate a signal for sounding from the sounding device 8. In a drive circuit 11, signals from the luminous energy arithmetic part 7 and the sounding part 10 are fetched to drive the sounding device 8. |
