Solenoid clutch controller for vehicle

Abstract

Abstract PURPOSE: To eliminate vibration of a vehicle body during the operation of engine brake, by interrupting a clutch current when a vehicle speed is lower than a set value and an intake manifold negative pressure is lower than a prescribed value. CONSTITUTION: A vehicle speed switch 51 turned on at over a set speed, and a negative pressure switch 52 switched on when negative pressure in an intake manifold is higher than a prescribed value are connected to a NAND gate 57, respectively. Output of the NAND gate 57 is input to a NAND gate 54 through an invertor 72 together with a signal sent from an accelerator switch 50. Output of the NAND gate 54 is fed to a NAND gate 55 together with a signal sent from a shift lever switch 53 to thereby control a current of a clutch coil 7. Since an intake manifold pressure signal is used, there is no possibility that a clutch current is interrupted during the operation of engine brake, whereby vibration of the vehicle body may not be generated.
