Lock-up controller of lock-up type automatic speed changer

Abstract

Abstract PURPOSE:To prevent generation of vibration of a car body, by stopping lock- up operation of a torque converter by a preset time when an accelerator pedal is again depressed after release of the pedal. CONSTITUTION:If an accelerator pedal is again depressed after release of the pedal, an idle signal S1, is switched to an H level, and this signal is inverted to an L level in a NOT gate 13 and fed to a NOR gate 14 while used for charge of a capacitor 17. In consequence, the NOR gate 14 is input with two signals both in an L level by the preset time determined by a resistor 16 and the capacitor 17, and an H level is output, then this signal is inverted to an L level in a NOT gate 15 and fed to an AND gate 22. Accordingly, lock-up control is neglected, and output of a lock-up signal SL can be inhibited.
