Abstract
Various implementations of a horn system include one or more force sensors disposed on a first portion of a driver air bag module and one or more actuators disposed on a second portion of the driver air bag module. For example, the force sensors may be disposed adjacent a perimeter of a base plate of the driver air bag module, and the actuators may extend inwardly toward the force sensors from an inner surface of a cover of the driver air bag module, or vice versa. To actuate the horn, the cover is moved axially toward the base plate, causing the actuators to apply force to the force sensors. Force signals received from the force sensors are used by one or more processors to determine characteristics of the force received and/or select a control message for communicating to the horn system based on the force signal characteristics.
