IPC: F02D41/12
Filed: 1984-10-24
Abstract: PURPOSE:To prevent stoppage of engine operation due to 'fuel-cut' while simplifying the wiring by making a brake signal unnecessary, by executing 'fuel-cut' by comparing the rate of change in the deceleration speed of a vehicle and making judgement whether the brake is acted for deceleration. CONSTITUTION:When pulse signals are furnished from a speed sensor 5 to a micro-processor 1, the time when the pulse signals are applied to the processor 1 is stored in a memory 2, and the period of said pulse signals is stored in the memory 2. Then the micro-processor 1 calculates the rate of change of the vehicle speed and makes comparison between the above rate of change with a reference value stored in the memory 2. In case that judgement is that the rate of change of the vehicle speed is equal to or higher than said reference value, judgement is made that the brake is acted fore deceleration, and fuel supplied to the engine is cut when the engine speed is lower than a first reference value and an throttle valve 7 is closed completely. With such an arrangement, it is enabled to simplify the wiring by making the brake signal unnecessary.
