<p>PURPOSE:To improve power performance, such as running stability, acceleration performance on the surface of road which has low coefficient of friction, etc. in such a way that engine output is controlled by detecting any slip of driving wheels to the surface of road. CONSTITUTION:When any slip is produced, control signals S1, S2 are applied as output in response to the slip rate from a slip discriminating circuit 10, and as a throttle valve control circuit 21 operates a servo motor 23 on the basis of the slip information from the control signal S1 taking priority of those signals from an accelerator pedal position sensor 22, the opening of a throttle valve 8 is getting smaller irrespectively of treading amount on an accelerator pedal (A). Thus, the engine output is lowered while the slip rate is lessened. In addition, opening rate of a control path 13 is made smaller in such a way that a solenoid valve 12 receives the control signal S2 in response to the slip rate, the exhaust bypass quantity increases by opening a valve 16, the supercharged pressure is lowered, and an engine torque 7 goes down.</p> |
