Abstract
The invention relates to a control system for preventing wheel spinning in the drive wheels of a motor vehicle with an engine with fuel injection. The control system has wheel speed sensing means and a processor unit which limits the quantity of fuel injected in steps in proportion to the wheel slippage. In a first step, the injected quantity is reduced to a cylinder by one half for example. In a second step, the fuel supply is completely shut off to this cylinder. The process then continues correspondingly by incremental shutting off of portions of cylinders until the wheel slippage drops, and the process is then reversed.
