Реферат: The invention discloses an electronic sound signaling system (100) that generates warning sounds in the forward and reverse mode of operation of a vehicle. The signaling system (100) incorporates an electronic circuit (120) with a standard automotive horn or alarm device (110) in place of mechanical contacts or circuit breakers. The electronic circuitry (120) includes electronically powered programmable microcontroller (130), a horn driver circuit, voltage sensing circuit, on a printed circuit board (PCB) Assembly and one or more sensors (140, 160, 170). The sound signaling system (100) uses the standard automotive horn device (110) to generate warning sounds in response to one or more sensor signals. The system (100) also performs multiple functions and is compatible to operate in different voltage ranges. The system has many advantages, including increased reliability, increased operating voltage range, reduced circuit complexity, reduced cost and reduced ambient noise.
