Claims

[Scope of utility model registration request]

(1) Automatic engine stop/start that captures the detection outputs of various sensors or circuits that detect the operating status of each part of the vehicle, and automatically stops or starts the engine under predetermined conditions based on these detection outputs. The device includes a blower that sends hot or cold air obtained from the near conditioner into the vehicle interior, a neutral switch that turns on when the transmission is switched to the neutral position, and a temperature control device installed at the air outlet of the near conditioner. A sensor receives the detection output of the temperature sensor and compares the temperature at the air outlet at the time of automatic engine stop with the temperature at any time after the engine automatically stops, and when the difference between these temperatures reaches a predetermined value or more, An automatic engine stop/start device comprising at least a control circuit that outputs a drive signal to the blower and outputs an automatic engine start signal when the Yoyutral switch is in an ON state.

(2) The control circuit includes a hold circuit that stores and holds the detection output of the temperature sensor at the time when the engine automatic stop signal is input, and compares the output signal of the hold circuit with the detection output of the temperature sensor. Claim (1) of the utility model registration claim is characterized in that the device includes a comparison circuit and an AND gate that takes a logical product of the comparison output of the comparison circuit and the detection output of the neutral switch. Automatic engine stop/start device. .
