Abstract

An intergated secruity, tip-over, and turn signal system for a motorcycle. The system provides multiple-functions with one control unit and a simplified wiring network. The system provides vehicle turn signal control including automatic turn-off of turn signal lamps at the end of a turn. The systems monitors the lateral forces acting on the motorcycle and disables the turn signal lamps, starter system, and fuel system when a tip-over condition is detected. For theft deterrence and prevention, the system allows a rider to disable the vehicle starter and ignition systems while the vehicle is parked. Tamper sensors in the system activate turn signals and an audible alarm if tampering is detected.
