Vehicle horn control system

摘要

A system for controlling a vehicle horn includes a current delivery circuit and a control circuit that controls the current delivery circuit in response to a horn activation signal received from a horn pad switch. The control circuit includes a control module that generates a horn termination signal if a duration of the horn activation signal exceeds a predetermined duration. The horn termination signal is configured to cause the current delivery circuit to prevent delivery of current to the horn to deactivate the horn. The control circuit further includes a bypass circuit configured to cause the current delivery circuit to deliver current to the horn to activate the horn responsive to the horn activation signal in the absence of the horn termination signal.

1. A system for controlling a vehicle horn, comprising:
a current delivery circuit configured to control delivery of current to said vehicle horn; and a control circuit configured to control said current delivery circuit in response to a horn activation signal received from a horn pad switch, said control circuit comprising:
a control module configured to generate a horn termination signal if a duration of the horn activation signal exceeds a first predetermined duration, the horn termination signal configured to cause said current delivery circuit to prevent delivery of current to the horn to deactivate the horn; anda bypass circuit configured to cause said current delivery circuit to deliver current to the horn to activate the horn responsive to said horn activation signal in the absence of said horn termination signal.
