Abstract: A control system for a torque converter lock-up clutch operates in a hydraulic circuit having line pressure applied to a lock-up clutch control valve and supplied selectively to a clutch-apply pressure chamber or a clutch-release pressure chamber. The control valve includes a valve spool, four control lands and a valve spring urging the control body to a starting position where the valve directs line pressure to the release pressure chamber and connects the apply pressure chamber to a cooler. When control pressure is applied, the valve spool moves to a shift-up position, supplies line pressure to the apply pressure chamber and connects the release-pressure chamber to an outlet line. A pulse-width modulated solenoid valve varies pressure in the release-pressure chamber by means of a throttle opening in the clutch plate, whereby control pressure is modulated so that force between the friction surfaces of the clutch is reduced to allow clutch slippage.

Abstract: A circuit arrangement for compensating for the temperature dependence of the sensitivity and of the null point of a piezoresistive pressure sensor having a temperature sensor thermally coupled thereto. The temperature sensor is coupled to an auxiliary amplifier, in the output circuit of which the feed diagonal of the pressure sensor is connected. The output diagonal of the pressure sensor is connected to an output amplifier, to which a temperature-dependent correction voltage can be applied on the input side via a resistor arrangement. To perform the compensation of the temperature dependence of the sensitivity independently of the temperature dependence of the null point, the resistor arrangement is connected directly to the output of the temperature sensor, preferably via jumpers.
