Auxiliary unit control module for use with existing remote vehicle control unit

摘要

A control unit for an auxiliary vehicle unit which may find particular application in conjunction with an already installed remotely activated vehicle control system, for example an original equipment manufacturer keyless entry or alarm system. An input is connected to a designated wiring of a vehicle which is triggered by the already installed remotely activated vehicle control system. It is then detected whether the designated wiring is triggered at least twice within a predetermined period of time. If it is determined that the designating wiring is triggered twice within the predetermined period of time, then the auxiliary unit is triggered. The auxiliary units may typically be a remote vehicle starter or window roll-up unit, and the designated wirings of the vehicle may typically be door lock or unlock wirings. <IMAGE>
