    • A power system (36) is disclosed as having a power source (22), a transmission (24) configured to receive a torque output from the power source and to drive a traction device (14), and an operator input device (18). The power system may also have a controller (27) configured to reference a signal from the operator input device with a map stored in memory to determine a corresponding speed of the power source, and to determine a margin between an actual and a maximum available torque output of the power source at a current speed. The controller may also be configured to selectively adjust a speed of the power source mapped to the maximum displaced position of the operator input device based on the margin, and to selectively adjust fueling of the power source at a current displacement position of the operator input device and operation of the transmission based on the signal and map.

    • 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.
    • 本发明涉及一种用于限制机动车辆(100,110)中的发动机(230)的转矩积分的方法,包括以下步骤:连续地识别(s410)与最大允许转矩(Tqmax)有关的模式, 并且通过将所述扭矩积分引导到所需扭矩(Tqreq)来响应扭矩需求(s420)。 该方法还包括以下步骤:通过连续地确定(s440)所述最大允许转矩(Tqmax)和主要转矩(Tq)之间的差(Tqdiff; Tqdiffnorm)来响应扭矩需求,以及 - 控制转矩积分( s460),使得所得到的转矩(Tq)是所述连续确定的差(Tqdiff; Tqdiffnorm)的函数。 本发明还涉及包含用于实现根据本发明的方法的计算机(200; 210; 500)的程序代码(P)的计算机程序产品。 本发明还涉及配备有该装置的装置和机动车辆(100; 110)。
