Method for managing a stall phase of an internal combustion engine associated with an electric motor

A method for managing a stall phase of an internal combustion engine associated with an electric motor in a vehicle including wheels, when an anomaly occurs during the course of a procedure to determine an angular position of the internal combustion engine, the method comprising, once a symptom of the anomaly is detected:

• implementing a diagnostics procedure to one or more of:
• (i) confirm the anomaly (and) (ii) determine an origin of the anomaly;
• reading an indicator informing as to a mechanical connection of the wheels to the internal combustion engine;
• in a case in which none of the wheels of the vehicle is connected to the internal combustion engine, commanding, by a management device, the electric motor to switch to a predetermined motor operating mode is maintained for as long as the diagnostics procedure remains uncompleted;
• and then
• commanding, by the management device, the electric motor to return to another operating mode in which the electric motor was operating before being switched to the predetermined motor operating mode.
