1. A vehicle comprising:

  • a vehicle body;

    drive wheels on the vehicle body;

    non-drive wheels on the vehicle body;

    an internal combustion engine in the vehicle body;

    a gear train for kinematically connecting the internal combustion engine to the drive wheels;

    said internal combustion engine comprising;

    an engine body having a plurality of cylinders;

    spark plugs arranged at each of the cylinders;

    intake means for introducing air into the cylinders;

    exhaust means for removing resultant exhaust gas from the cylinders;

    fuel introducing means for introducing an amount of fuel into the intake means for defining a combustible air-fuel mixture to be introduced into the cylinders;

    means for controlling the amount of fuel to be introduced into the intake means from the fuel introducing means for controlling the air-fuel ratio of the air-fuel mixture;

    means for controlling timing of a spark signal to each spark plug to obtain a desired ignition time;

    means, responsive to a knocking condition of the engine, for adjusting said desired setting of the ignition timing for suppressing knocking in the engine;

    means for detecting the speed of the drive wheels of the vehicle;

    means, based on the detected value of the drive wheel speed, for detecting slippage of the drive wheels when the vehicle is accelerated;

    means, based on the detected slippage at the drive wheels, for allowing a setting of the torque applied to the drive wheels to be reduced, to suppress slippage during an acceleration of the vehicle; and

    means for cancelling the operation of the knocking control means so that a control of the ignition timing based on the engine knocking condition is stopped during the operation of said torque control means.
