PURPOSE:To enable to simplify a circuit, by a method wherein an alarming device is commonly used through combination of an alarming device, which generates an alarming signal only during a stop, with an alarming device, which generates an alarming signal only during running, by means of an OR circuit. CONSTITUTION:During a stop, when from the condition of each of switches 2a-2d of a first alarming signal generating circuit 2, a key is decided to remain inserted in a key hole, an alarming signal is outputted from an AND circuit 21, and when a seat belt is decided to remain unbelted, an alarming signal is outputted from an ADN circuit 22 for a specified time set by a timer 26. Further, during running of a vehicle, when a gear transmission instruction signal is outputted from a second alarming signal generating circuit 3, an alarming lamp 12 is lighted and simultaneously, an alarming signal is outputted. The alarming signals from the two circuits 2 and 3 are combined together by an OR circuit 4 to perform alarm through a single alarming device 5, but since the former is outputted during a stop and the latter during running, the one can be alarmed in distinction from the other even if there is no priority order. |
