PURPOSE:To make a proper shift-up indication attainable all the time, by comparing the setting value, made into the larger the lower in engine temperature, with the actual value of an engine speed and, when the actual value is larger than the setting value, letting a device perform the shift-up indication. CONSTITUTION:A device bearing the above caption compares the speed detection value by an engine speed detecting device 1 with the speed setting value by a setting value generating device 2 by a comparing device 3. And, when the speed detection value is larger than the setting value, it outputs a signal for a shift-up indication to a shift-up indication device 4 of a lamp or a buzzer or the like from this comparing device 3. In this case, there is provided with an engine temperature detecting device 5 which detects a warming-up state of an engine, and it is constituted so as to make the setting value, to be generated at the generating device 2, larger the lower in the engine temperature detection value. With this constitution, even at the time of engine temperature being low, a proper shift-up indication is made so as to be giveable all the time. |
