Abstract

A vehicular control system (1) for an electric traction system (ET) of a vehicle (V) with electric or hybrid propulsion, the vehicle (V) with electric or hybrid propulsion comprises a vehicular powertrain (GM) comprising the electric traction system (ET) and a transmission system (T) interposed between the electric traction system (ET) and driving wheels (W) of the vehicle with electric or hybrid propulsion (V). The electric traction system (ET) comprises at least one multiphase electric motor (ME) and is electronically controllable to selectively operate in different operating modes comprising at least one electric mode, wherein the vehicle (V) with electric or hybrid propulsion is propelled by the electric motor (ME). The vehicular control system (1) is designed to determine (10) the presence of a possible critical condition of the electric traction (ET) system of the vehicle (V) with electric or hybrid propulsion; in case a possible critical condition of the electric traction system (ET) of the vehicle (V) with electric or hybrid propulsion is determined to be present, inhibit (11) first phases of the electric motor (ME) of the vehicle (V) with electric or hybrid propulsion; verify (12) that the position of a rotor of the electric motor (ME) of the vehicle (V) with electric or hybrid propulsion meets a proprietary criterion; and if the position of a rotor of the electric motor (ME) of the vehicle (V) with electric or hybrid propulsion meets the proprietary criterion, inhibit (13) the remaining second phases of the electric motor (ME) of the vehicle (V) with electric or hybrid propulsion.
