Claim 13:
14. System for safe actuation of auxiliary traction in road implements comprising a control system communicating with an operation panel, wherein the operation panel is provided with at least one traffic route of the road implement, the said traffic route containing data of the altimetric route profile, wherein:
the control system, provided with an algorithm, selects operating modes from the data of the altimetric route profile, with the operating modes being at least one of i) traction, ii) regenerative braking, iii) free shaft, or a combination thereof;
the control system is provided with a security mode operation, where the control system is set as default to initiate and maintain in the operating mode iii) free shaft; and
the control system is provided with a rationalizing function, wherein the control system receives predictive information of ramps and slopes being comprised in the data of the altimetric route profile;
said rationalizing function choosing one or more ramps or slopes of the route to select the operating modes i) traction or ii) regenerative braking, after the control system identifies whether predefined multiple safety requirements are fulfilled;
wherein the control system returns to the iii) free shaft mode, when the predefined multiple safety requirements are unfulfilled.
