ABSTRACT:
In a traction controller for cutting fuel supply to the cylinders of a multi-cylinder engine based on a slip factor of the drive wheels of a vehicle, an ordinary fuel cut mode in which fuel is cut to only some cylinders and a multi-cylinder fuel cut mode in which fuel is cut to a larger number of cylinders are provided. When the slip factor exceeds a first threshold value, ordinary fuel cut begins, and when the fuel cut duration time exceeds a predetermined value and the slip factor exceeds a second threshold value higher than the first threshold value, multi-cylinder fuel cut is performed. In this way, the drive wheels are prevented from slipping while preventing hunting of the slip factor due to multi-cylinder fuel cut and temperature rise of a catalytic converter.
