PURPOSE:To ensure the precise control of the subject device as controlled on an output signal from an outside temperature sensor by memorizing said output signal available when an engine stop has been detected, and controlling on reading out the memorized output signal for a predetermined time in re-starting the engine. CONSTITUTION:Outside temperature 201, ignition-switch-off information 202, engine cooling water temperature 203 and car speed 204 are outputted into the outside temperature correction part 300 of a control device 200. And when an engine stop signal has been inputted from an ignition switch 202, the corresponding value of the outside temperature sensor 201 is recorded. Also, when the ignition switch 202 is ON and the water temperature 203 is over a predetermined level, an engine is judged as just started and the outside temperature 201 as memorized is read out, thereby estimating actual outside temperature. And after a predetermined time has passed and it has become possible to detect the actual outside temperature, the subject device returns to normal control. According to the aforesaid constitution, control can be made with precise outside temperature. |
