Claims

[Scope of Claim for Utility Model Registration] An engine rapid preheating control device for a vehicle engine, comprising: a glow plug attached to a preheating point of the engine; an entry detection means for detecting when a driver enters the vehicle; and a vehicle key. a switch, an opening/closing element provided in a power supply path from the vehicle battery to the glow plug without going through the key switch, and a first control signal for generating a first control signal for closing the opening/closing element in response to activation of the key switch. 1, a signal generating means, a timer means for generating a timer signal until a predetermined time elapses in response to the detection signal of the occupancy detecting means; starting at the rising edge of the timer signal of the timer means;
a second signal generating means that generates a second control signal for closing the opening/closing element from the start to the end, the second signal generating means ending at the fall of the timer signal or the first turning on of the key switch; An engine rapid preheating control device comprising: driving means for driving the opening/closing element under a logical sum condition of the first and second control signals of the first and second signal generating means.
