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.

Abstract
A slip control system for a vehicle provided with an internal combustion engine having a knocking control system for controlling an ignition timing retarding amount in accordance with a degree of knocking detected by a knocking sensor mounted on a body of the engine. The slip control system controls the torque applied to drive wheels of the vehicle in accordance with a degree of slip generated at the drive wheels. A circuit is provided for cancelling the operation of the knocking control system during the operation of the slip control system.
