<p>The invention relates to a method for regulating the speed of an engine (230) in response to extra load, comprising the step of - continuously determining (s410) a prevailing speed (n) of said engine. The method comprises also the steps of - determining (s430), upon activation of extra load (s420), a maximum permissible engine speed set-point value (n_init) and a corresponding power mobilisation reference (TH_ref) for the regulation of said speed (n), - regulating (s450) said speed (n) towards said maximum permissible set-point value (n init; n_refMax) when more power is being mobilised than said power mobilisation reference (TH_ref), and - regulating (s450) said speed (n) according to a specific relationship between engine speed set-point value (n_ref) and power mobilisation (TH) when less power is being mobilised than said power mobilisation reference (TH ref). The invention relates also to a computer programme product comprising programme code (P) for a computer (200; 210) for implementing a method according to the invention. The invention relates also to a device for regulating the speed of an engine (230) in response to extra load, and to a motor vehicle (100; 110) equipped with the device.</p> |
