Abstract

PURPOSE:To positively promote the awakening of a driver by starting an air conditioner for cooling air, when the abnormality in the running condition is detected, and jetting the cooling air to the face of the driver. CONSTITUTION:The awakening actuator 44 of an awakening device 40 is ordinally kept in the state of shutting an opening/closing door 43 and therefore cooling air is not subjected to flow in a cooling air taking out duct 41 so that the cooling air is not blown from a cooling air nozzle 42. The other hand, when the running condition is judged to be abnormal analyzing the information from an abnormality detecting sensor 45 through a judging part 46, the awakening actuator 44 is indicated, on the basis of this judgement, by the control circuit 34 of a control part 30 for making the opening/closing door 43 open. Therefore, the cooling air just behind the evaporator 21 of a refrigerating cycle is taken out to the cooling air taking out duct 41 so as to jet the cooling air from the cooling air nozzle 42 to the vicinity of the face of the driver A and thereby it is possible to awake the driver A.
