Abstract
A system for controlling an output power of an internal combustion engine having a plurality of cylinders for use in a traction control system including a wheel slippage detecting portion for detecting a wheel slippage, a command portion for determining an amount of a change in the output power of the engine in accordance with the detected wheel slippage, a control portion responsive to the amount of a change in the output power of the engine to provide a first control command for effecting a fuel cut-off control and a second control command for effecting an ignition timing retard control, a first control portion for performing the fuel cut-off control in accordance with the first control command, and a second control portion for performing the ignition timing retard control in accordance with the second control command, wherein when the first control command requires a change in the number of resting state, the ignition timing retard control is delayed such that the control of the output power of the engine can be carried out smoothly without causing undesired aberration in the output power.
