Flasher for motor vehicles providing distinctive hazard-flash patterns to signal rapid deceleration and other hazards

摘要

A flasher-control system for motor vehicles which automatically provides two different flash patterns for signaling with vehicle's turn-signal/hazard-signal lamps: (1) uniform patterns for turn signals, and (2) distinctive non-uniform sequences for hazard alerts The distinctive non-uniform, hazard-alert flash sequence is used: (a) to signal very rapid deceleration of a vehicle when triggered by a deceleration sensing means, and (b) to signal other hazards when activated by the driver. The purposes of the distinctive non-uniform, hazard-alert flash are, compared to conventional turn-signal-rate hazard flashers, to make hazard-alert signals readily distinguishable from turn signals and to make such signals more conspicuous, striking and attention getting and thus more effective in signaling hazards. A lamp-out detector is included which can be used with any number and combination of incandescent and LED lamps, including a vehicle with all LED signal lamps.
