  • System for controlling coupling force of a fluid coupling
    Patent number: 5141089
    Abstract: The coupling force of a fluid coupling interposed between the combustion engine and the driving wheels is controlled when the automotive vehicle is decelerated. When the automotive vehicle is brought into a decelerated state, the supply of fuel to the combustion engine is suspended by cutting the fuel off. The control of cutting fuel off is delayed by a given period of time after the control over the coupling force of the fluid coupling has been started. The given delay time is so set as to correspond to the state in which the fluid coupling slips.
