Abstract

PURPOSE: To avoid shocks from abrupt actions of the engine brake applied at a speed faster than the set value by realizing a buffer coupling by gradually increasing the electromagnetic clutch excitation when the car speed reaches the predetermined speed while the acceleration pedal is kept in the free state.
CONSTITUTION: During car run on a down slope, if the acceleration pedal is not pressed and a switch 9 is at the OFF position, when the speed is below the set value and a switch 10 is at the OFF position, a transistor 2 is turned off and a coil 1 of the clutch is not excited. When the speed increases and reaches the set value, the switch 10 is turned on and a signal of H level is inputted a switching circuit 18. At the same time, a mode sensor 22 turns on the transistor of an instantaneous switching control circuit 21 and lets a capacitor 214 discharge. Therefore, the circuit 18 selects output of an oscillator 17 for a predetermined length of time and the output drives the transistor 2, gradually increasing the excitation current of the coil 1. Thus, the engine brake is applied gradually without generating shocks.
