ABSTRACT:
A vehicle turn signal system (10), and an associated method, utilizes turn selectors (14, 16) located on a steering wheel (12). The system has right and left turn signal indicator circuits (34, 38) that are each energizable to indicate an intended movement of the vehicle toward the right or left, respectively. A micro-controller 20 controls the energization of the right and left turn indicator circuits (34, 38). Each of the right and left selectors (14, 16) is actuatable in a first manner for causing the micro-controller (20) to energize the respective indicator circuit (34 or 38) to perform a first indication operation and actuatable in a second manner for causing the micro-controller to energize the respective indicator circuit (34 or 38) to perform a second indication operation. In one embodiment, the first manner of selector actuation is a relatively short duration actuation, and the second manner of selector is a relatively long duration actuation. Also, in one embodiment, the first indication operation is a timed duration indication for lane changing and the second indication operation is conventional turn indication (e.g., indication until cancelled).
