车辆的冷却系统
摘要：
本发明提供一种车辆的冷却系统，具备：流路（116），其使冷却车辆的驱动装置的液体介质循环；流量检测部（114），其检测在流路中流动的液体介质的流量；温度传感器，其检测液体介质的温度；泵，其设置在流路上，用于使液体介质循环；转速传感器，其检测泵的转速；以及控制装置（30），其控制泵的驱动。控制装置根据液体介质的流量、液体介质的温度以及泵的转速，确定冷却系统的不良部位。由此，能够更详细地区别并检测冷却系统的异常，因此，修理时应该确认的部位被限定，作业效率得到改善。
摘要（英）：

A cooling system for a vehicle is equipped with: a flow passage (116) that circulates a liquid medium that cools a drive device of the vehicle; a flow amount detection unit (114) that detects the amount of liquid medium flowing through the flow passage; a temperature sensor (108) that detects the temperature of the liquid medium; a pump (104) that is provided on the flow passage and circulates the liquid medium; a rotation speed sensor (105) that detects the rotation speed of the pump; and a control device (30) that controls the driving of the pump. The control device (30) specifies a failure site of the cooling system based on the flow amount of the liquid medium, the temperature of the liquid medium, and the rotation speed of the pump. Abnormalities in the cooling system can thus be detected and distinguished in greater detail, thereby limiting the number of locations that should be checked during repairs and improving work efficiency.
