Excess slip control device for driving wheel.

摘要

An excess slip control device for a driving wheel 11,12, comprising a driving wheel speed sensor 21,22 for detecting a driving wheel speed Vw of a vehicle 1, a slip determining means 35 for determining a slip condition of a driving wheel 11,12 according to an output from the driving wheel speed sensor 21,22, a fuel supply suppressing means 35 for suppressing fuel supply to an engine 31 according to an output from the slip determining means 35, and a retard control means 35 for controlling an ignition timing to a retard position according to an output from the slip determining means 35. Thus, the fuel quantity to be supplied to the engine and the ignition timing are controlled according to the slip condition of the driving wheel. Accordingly, an operational shock due to a fluctuation in engine torque may be reduced to thereby improve the drivability, and a control lag may be also eliminated.
