  • Control system for power transmission device for vehicle
    Patent number: 10190681
    Abstract: A protection control selection unit is provided. The protection control selection unit selects control that uses one of a completely engaging heat generation amount and a releasing heat generation amount, by which the amount of heat that is generated in a lockup clutch is reduced. The completely engaging heat generation amount is generated in the lockup clutch in a period before the lockup clutch is completely engaged from a state of lockup engagement control. The releasing heat generation amount is generated in the lockup clutch in a period before the lockup clutch is released from the state of the lockup engagement control. Thus, an increase in the temperature of the lockup clutch at the time when the lockup clutch is completely engaged or released from the state of the lockup engagement control is suitably suppressed.
