Abstract: A method determines a force to be transmitted to driving wheels of a vehicle provided with a hybrid power train with several gear ratios and a traction battery. The method includes determining, over all of a speed range that the vehicle is capable of achieving, a maximum force that the power train is theoretically capable of transmitting to the wheels in predetermined nominal conditions of charge of the traction battery and/or of outside temperature and/or of atmospheric pressure; and determining, over all of the speed range, a drivability force that the power train is capable of transmitting to the wheels. The drivability force confirms that whatever the value of the speed of the vehicle, the drivability force is less than or equal to the maximum force; and the drivability force evolves within the speed range without exhibiting an inflexion point at values of the speed requiring a gear change.

Abstract: A method for reducing energy of torque for electrically boosting acceleration of a hybrid vehicle including a power train, a heat engine, an electric machine capable of jointly or separately outputting a torque to a wheel in accordance with management laws optimizing energy consumption of the vehicle, and a traction battery which is capable of recovering all or part of kinetic energy of a decelerating vehicle in a form of electric energy, and rechargeable via the heat engine. In the method electric boost torque available for the torque boost is reduced by a reduction coefficient of 0 to 1 according to an amount of energy remaining in an energy range of the battery reserved for the torque boost.

Abstract: A method for managing energy in response to a request of a driver for torque on a power train of a hybrid vehicle including a heat engine and at least one electric motor powered by a battery, capable of recovering energy during deceleration in accordance with a management rule distributing the energy supply from the heat engine and from the electric motor in real time. The energy-management law depends on: an equivalence factor that is based on an instantaneous energy state of the battery, an energy target, and travel conditions of the vehicle; and a discharge precompensation factor that is based on energy potential that can be recovered during deceleration.
