    • PROBLEM TO BE SOLVED: To prevent inconvenience from being caused by low oil temperature, even when oil temperature estimating accuracy is poor.
      SOLUTION: An electronic control unit 10 starts time counting by a timer 22 when an IG detecting means 21 detects that an ignition switch is turned off, and acquires the cooling water temperature of engine cooling water at its time from a cooling water temperature sensor 18, and preserves its value in a memory 23. The electronic control unit 10 finishes the time counting of the timer 22 when the IG detecting means 21 detects that the ignition switch is turned on, and preserves counted time in the memory 23 as elapsed time. The electronic control unit 10 estimates the final arrival temperature (that is, the substantial outside air temperature) of the oil temperature, by executing predetermined arithmetic operation processing, by using the elapsed time and the last time engine cooling water temperature preserved in the memory 23 and the engine cooling water temperature acquired this time from the cooling water temperature sensor 18 in outside air temperature estimating processing the later.

    • 要解决的问题:为了防止由油温低引起的不便,即使油温估计精度差。 解决方案:当IG检测装置21检测到点火开关被关闭时,电子控制单元10开始计时器22的计时,并且从冷却水温度获取发动机冷却水的冷却水温度 传感器18,并将其值保存在存储器23中。当IG检测装置21检测到点火开关被接通时,电子控制单元10完成定时器22的计时,并将经过的存储器23中的计时时间保留 时间。 电子控制单元10通过使用保存在存储器23中的经过时间和最后一次发动机冷却水温度执行预定的算术运算处理来估算油温的最终到达温度(即实际的外部空气温度) 以及此后从外部空气温度估计处理中的冷却水温度传感器18获取的发动机冷却水温度。 版权所有(C)2010,JPO&INPIT
