    • The invention relates to a method for limitation of torque build-up of an engine (230) in a motor vehicle (100, 110), comprising the steps of - continuously identifying (s410) a pattern pertaining to a maximum permissible torque (Tqmax), and - responding to torque demand (s420) by guiding said torque build-up towards torque desired (Tqreq). The method comprises also the steps of - responding to torque demand by continuously determining (s440) a difference (Tqdiff; Tqdiffnorm) between said maximum permissible torque (Tqmax) and a prevailing torque (Tq), and - controlling the torque build-up (s460) so that the resulting torque (Tq) is a function of said continuously determined difference (Tqdiff; Tqdiffnorm). The invention relates also to a computer programme product containing programme code (P) for a computer (200; 210; 500) for implementing a method according to the invention. The invention relates also to a device and a motor vehicle (100; 110) equipped with the device.

    • The present invention proposes a system for regulation of torque demanded Tq demand from a prime mover of a vehicle, which prime mover is adapted to responding to the torque demanded Tq demand by delivering a dynamic torque Tq fw . This dynamic torque Tq fw is related by a gear ratio i to a dynamic wheel torque Tq wheel which a power train comprising the prime mover is adapted to imparting to at least one tractive wheel of the vehicle. According to the present invention the system is adapted to conducting the regulation of the torque demanded Tq demand in such a way that a difference between the torque demanded Tq demand and the dynamic torque Tq fw is actively limited by employing feedback of the dynamic torque Tq fw (t— Δ t) at an earlier time t— Δt . The torque demanded Tq demand at a time t for the regulation is here limited to a maximum value Tq demand,max which exceeds the dynamic torque Tq f W (t— Δt) at an earlier time t— Δt by an offset value Tq offset max , i.e. Tq demand,max (t) = Tq fw (t - Δ t) + Tq offset>max . The torque demanded Tq demand is thus continuously varied according to the dynamic torque Tq fw , so that power train oscillations in the vehicle are reduced in number and/or magnitude.
    • 本发明提出了一种用于调节来自车辆的原动机的扭矩要求的Tq需求的系统,该系统通过传递动态转矩Tq fw来适应对扭矩要求的Tq需求。 该动态转矩Tq fw与齿轮比i与动力轮转矩Tq轮相关联,动力轮转矩Tq轮包括原动机的动力传动系适用于赋予车辆的至少一个牵引轮。 根据本发明,该系统适于以这样的方式进行扭矩要求的Tq需求的调节,使得通过使用动态转矩Tq fw的反馈主动地限制需求的扭矩Tq需求与动态转矩Tq fw之间的差 (t-&Dgr; t)在更早的时间t-&Dgr; t。 这时需要在时间t的Tq需求在这里被限制在最大值Tq需求max,其最大值超过在较早时间t-&Dgr; t处的偏移量的动态转矩Tq f W(t-&Dgr; t) 值Tq offset max,即Tq需求,max(t)= Tq fw(t - &Dgr; t)+ Tq offset> max。 因此,要求的Tq需求的扭矩根据动态转矩Tq fw而不断变化,使得车辆中的动力传动系振动数量和/或幅度减小。
