    • A controller (6) computes an oxygen storage amount of a catalyst (3) separately as a high speed component/amount and a low speed component/amount according to predetermined release/adsorption characteristics. A target air-fuel ratio of an engine is computed and the air-fuel ratio of the engine is controlled so that the high speed component is maintained constant. The target air-fuel ratio of the engine (1) is limited by an upper limiter and lower limiter so that the high speed component converges to the target value, an excessively large variation of the air-fuel ratio is prevented, and impairment of drivability and fuel cost-performance is also prevented. Further, after lean running due to fuel cut, etc., the lower limiter is lowered to the rich side, and the oxygen storage amount is rapidly induced to converge on the target value.
    • 控制器(6)根据预定的释放/吸附特性,分别计算催化剂(3)的氧气存储量作为高速成分/量和低速成分/量。 计算发动机的目标空燃比,并且控制发动机的空燃比,使得高速分量保持恒定。 发动机(1)的目标空燃比由上限制器和下限制器限制,使得高速分量收敛到目标值,防止空燃比变化过大,驾驶性能受损 并且还防止燃料成本性能。 此外,由于燃料切断等而在稀薄运行之后,下部限制器被降低到浓侧,并且迅速地使氧气储存量收敛于目标值。

    • The invention relates to a method for influencing a torque conveyed by a driving motor of a motor vehicle. According to the inventive method, load alternation that occurs during cornering of the motor vehicle is detected. A minimum value of an intervening variable which influences the conveyed torque is detected when load alternation occurs during cornering and the driving motor is impinged upon with the minimum value of the intervening variable for a given time. The aim of the invention is to improve the load alternation behaviour of the motor vehicle during cornering and to improve performance of the motor vehicle in overrun. The detected minimum value of the intervening variable and/or the time is/are corrected according to the friction coefficient of a roadway and/or according to a deceleration of the motor vehicle, whereby the motor vehicle drives on said roadway.
