チ制御装置。 A drive system clutch means 10 is provided in the middle of an engine drive system that transmits engine driving force to the front and rear wheels, and connects the front and rear wheels to a direct drive connection state by means of an external clutch engagement force, and detection means 23a, 23b,
In a drive system clutch control device for a four-wheel drive vehicle, the clutch control means 23e outputs a control signal for increasing or decreasing the clutch engagement force based on an input signal from the clutch control means 23c, and the presence or absence of program runaway of the clutch control means is constantly monitored. The four-wheel vehicle is characterized in that it is equipped with a monitoring circuit 243 that detects the presence or absence of a program runaway, and power source operation cutoff circuits 246 and 25 that control on/off the operating power source of the drive train clutch means by detecting the presence or absence of program runaway. Drive train clutch control device for drive vehicles.
