A system for controlling an electro-magnetic clutch of an internal combustion engine mounted on a car which is capable of eliminating residual magnetism during the deceleration of the car. The electro-magnetic clutch has a drive member secured to a crankshaft of the internal combustion engine, a driven member adjacent the drive member and a magnetizing coil provided in one of the members. An accelerator switch is provided for detecting the deceleration of the car and a car speed switch is provided for producing a signal when the car speed decreases below a predetermined speed. Both of output signals of the accelerator switch and the car speed switch are fed to a control circuit. The control circuit is such that the current flowing through the magnetizing coil is inverted upon occurrence of these output signals of the accelerator switch and the car speed switch, so that the residual magnetism in the clutch is eliminated.

A speed change control system for an automatic transmission for motor vehicles having a planetary gear mechanism and a brake band for altering the transmission ratio. The system is to tighten gradually the brake band. The system comprises a servo-piston, a piston rod secured to the servo-piston and to the brake band, and an accumulator piston axially slidably disposed in the bore of the servo-piston. The servo-piston is biased by a first spring for returning the servo-piston for releasing the brake band, and the accumulator piston is biased by a second spring. Apply side and release side oil chambers are formed on opposite sides of the servo-piston, and an accumulator oil chamber is formed by the accumulator piston in the bore. Pressure oil is applied to the apply side oil chamber, so that the servo-piston moves in a brake band engagement direction against the first spring. After that, the accumulator piston moves a predetermined stroke against the second spring. Thereafter, the accumulator piston engages with the servo-piston, so that both pistons move together for tightening the brake band.
