METHOD AND DEVICE FOR LIMITING THE TORQUE BUILD-UP OF AN ENGINE

摘要

A method for limitation of torque build-up of an engine (230) in a motor vehicle (100, 110), including the steps of continuously identifying (s410) a pattern pertaining to a maximum permissible torque (Tqmax); responding to torque demand (s420) by guiding torque build-up towards desired torque (Tqreq); responding to torque demand by continuously determining (s440) a difference (Tqdiff; Tqdiffnorm) between 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 the continuously determined difference (Tqdiff; Tqdiffnorm). Also a computer program product containing program code (P) for a computer (200; 210; 500) for implementing a method according to the invention. Also a device that performs the method and a motor vehicle (100; 110) equipped with the device are disclosed.

1. A method for limitation of torque build-up of an engine in a motor vehicle, comprising the steps of:
continuously identifying a pattern pertaining to a maximum permissible torque (Tqmax); responding to torque demand by guiding said torque build-up towards a desired torque (Tqreq); and responding to torque demand (Tqreq) by continuously determining a difference (Tqdiff; Tqdiffnorm) between said maximum permissible torque (Tqmax) and a prevailing torque (Tq); and controlling the said torque build-up towards said maximum permissible torque (Tqmax) so that the resulting torque (Tq) is a function of said continuously determined difference (Tqdiff; Tqdiffnorm).
