PURPOSE:To facilitate the subsequent processes by issuing a warning to expedite the connection of a power transmitting system it the suction supplied to a servo unit is weakened when the engine is not making self sustaining operation, and by issuing a warning to tell abnormal condition of the servo unit when the suction is still weak even after self sustaining operation of the engine is established. CONSTITUTION:If the suction supplied to a sero unit is weakened beyond the set level of suction when the engine is stopped, and a suction switch 26 is ON. As L terminal voltage VL of an alternator 9 is under a definite voltage VS, the output of a comparator 10 becomes ''1''. At that time, if a transmission gear is in either position of 5, 4, or 3 speed, the clutch is cut, and the clutch switch 8 is ON, each output from and-gate 32 and 33 is set to ''1'', and a warning expediting the connection of the clutch is issued from a speaker 35. On the other hand, even after the output of the comparator 10 is set to 0 by operation of the engine, if the suction switch 26 is ON, the warning apparatus 41 is operated, and the trouble of the servo unit is announced. |
