Patent Images
1. A driving wheel slip device for a vehicle which as an engine, comprising:
- slip detecting means for detecting a slip condition of a driving wheel;
fuel supply means for reducing a fuel supply to an engine of the vehicle in response to an output of said slip detecting means; and
ignition control means for reducing a spark energy of an ignition plug of the engine, in synchronization with said fuel supply control means, wherein said ignition control means comprises ignition timing changing means for changing ignition timing of the engine from a standard ignition timing under a normal fuel supply control to an advanced ignition timing, in synchronization with said fuel supply control means, said ignition timing changing means comprising;
advanced ignition timing setting means for determining a set value of an advanced ignition timing which is advanced by a predetermined amount from said standard ignition timing, wherein an output from said advanced ignition timing setting means controls the ignition timing based upon said set value.
