PROBLEM TO BE SOLVED: To appropriately cool an engine when the engine tends to be overheated. SOLUTION: After determining whether the temperature of cooling water is lower than 100 deg.C at S101, when the temperature of the cooling water is lower than 100 deg.C, the next step to proceed to is S102 where engine operation in idling is stopped by cutting fuel. When the temperature of the cooling water is 100 deg.C or more, the next step to proceed to is S103 where a cooling water temperature elevated alarm is operated and a water temperature alarm lamp 31 is lighted, followed by proceeding to S104. At S104, it is determined whether SOC of a main battery is left more than 80%, and when the SOC is left more than 80%, the next step to proceed to is S105 where a motor A2 is rotated to continue circulation of the cooling water of the engine 1 and ensure cooling of the engine 1. And when the SOC of the main battery is determined to be left 80% or less at S104, the next step to proceed to is S106 where the engine 1 is operated to perform normal idling rotation and continue the circulation of the cooling water of the engine 1 to ensure cooling thereof. |
