Abstract
A method for controlling and monitoring a hybrid vehicle including a driving internal combustion engine, and an electric machine that is operational, upon an instruction, in a form of a driving engine and is powered by a battery. The method detects a vehicle operating state, in transmitting, in response, an operating instruction to the electric machine only, without requesting any particular instruction from the internal combustion engine and respecting the vehicle stability constraint and a protecting constraint of the electric components thereof.

1-11. (canceled)
A method for controlling and supervising a hybrid vehicle including a driving engine, and an electric machine able on command to operate as a driving motor and supplied by a battery, the method comprising:
- detecting an operating state of the vehicle;
- and
- producing in response an operating setting for the electric machine only, without demanding any particular control of the engine, while ensuring compliance with a stability constraint for the vehicle and with a protection constraint for electrical items of the vehicle.
A device for controlling and supervising a hybrid vehicle comprising:
- a driving engine;
- an electric machine able on command to operate as a driving motor and supplied by a battery;
- a first module that detects an operating state of the hybrid vehicle, which produces an operating state vector;
- and
- a second module that makes it possible to establish a setting on the basis of the operating state vector, the second module cooperating with a stability control unit for the vehicle and an electrotechnical protection unit for electrical items of the vehicle, the setting being applied to the electric machine alone of the hybrid vehicle.
