Abstract
A multi-function electronic warning horn system comprises a couple of horns (1, 2) and a microprocessor (6), integrated in an electronic module (16) comprising a voltage adjuster (13), an oscillator (17), power stages (3, 4) and a control circuit (7). Horns (1, 2) are controlled by either the push-button (5) of the steering wheel for the traditional function of acoustic signaling or by a coded signal transmitted to microprocessor (6) by the “intelligent” electronic unit or onboard computer of the vehicle for the function of buzzer.
Claims10
A multi-function electronic horn warning system for a motor-vehicle having an onboard computer and a push-button (5) in communication with the onboard computer, said system having an acoustic warning function and a signalling buzzer function wherein the signalling buzzer function provides notification of a state of the motor-vehicle by generating sound cycles, said horn warning system comprising:
- a horn (1;2) activated by the push-button (5) and the onboard computer,
- an electronic module having a control circuit (7) connectable to the push-button (5) and to the onboard computer, a voltage adjuster (13), a ceramic resonator (17) and a power stage (3;4) connected to the horn,
- said electronic module having a programmable microprocessor (6) controlled by said control circuit (7) and connected to the power stage (3;4) for activating the horn in said acoustic warning and signalling buzzer functions, said programmable microprocessor having software that allows a user to program and modify the sequence, duration, frequency and sound level of said sound cycles.
