Embodiment Construction

[0013] The system described herein can be used to control a vehicle horn in a manner that extends the range of use of the horn while also protecting the horn from damage over time. Specifically, the system employs a control module to prevent current delivery to the horn if the horn pad switch is stuck or activated for too long, while also employing a bypass circuit that allows relatively short periods of activation of the horn that would otherwise The relatively short duration activation of the horn will be excluded by the debounce circuit of the control module.

[0014] Referring now to the drawings, wherein like reference numerals are used to identify like parts throughout the several views, figure 1 One embodiment of a vehicle horn assembly 10 is shown. Assembly 10 may include a horn 12 , a horn pad switch 14 , a clock spring 16 and one embodiment of a system 18 for controlling horn 12 .

[0015] Horn 12 may produce sound in response to activation of switch 14 by a vehicl...

Abstract

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.

Description

technical field [0001] The present invention generally relates to a vehicle system. More particularly, the present invention relates to a system for controlling a horn of a vehicle, which can extend the usage range of the horn while protecting the horn from damage. Background technique [0002] Vehicle horns are provided to enable the driver of a vehicle to warn other vehicles and pedestrians of a possible collision or other hazardous situation. A typical vehicle horn employs an electromagnet that is actuated in response to movement of a horn pad switch, causing a metal diaphragm to move in an oscillating motion and emit sound. The horn may be damaged if it is activated for too long. Therefore, a control module is usually inserted between the horn pad switch and the horn to allow improved control of the horn's response to the horn pad switch, in particular, enabling the horn to be deactivated if the horn pad switch becomes stuck. While the control module protects the horn...
