The state of charge of a traction battery of a hybrid vehicle power train is managed by, during a phase of running of the vehicle to a current destination, predicting a temperature that a battery will reach, after the power train is switched off, at a time of departure to a future destination; estimating, as a function of the battery temperature previously predicted, a minimum state of charge of the battery making it possible to provide, during a phase of running to the future destination, a predefined minimum power level; and maintaining the state of charge of the battery close to the minimum state of charge.

The battery model parameters are adjusted during vehicle operation using a Kalman filter and reinitialized to new values in response to a vehicle key-on, in response to a change in the battery current exceeding a corresponding threshold, and/or in response to any of the parameter values crossing an associated limit.

A method and system controller includes determining a power requirement for a vehicle system to complete a planned trip over a route. The method includes determining whether an amount of available power from the vehicle system is sufficient to propel the vehicle system to complete the planned trip by comparing the available power with the power requirement that is determined. The method includes changing one or more operational aspects of the planned trip based on the comparison between the amount of available power and the power requirement that is determined to generate a newly planned modified trip.

Method for determining predicted acceleration information which describes a future acceleration potential of an electric vehicle having an electric motor as the drive device, which is supplied with electric power from a battery in the electric vehicle, this method including the following steps: —Supplying power predictive information of the electric motor, which describes the predicted available acceleration power of the electric motor for at least one future period of time, —Determining the acceleration information from the power predictive information by using a vehicle model which supplies the prevailing operating state of the electric vehicle, at least one vehicle parameter describing the acceleration possible on the basis of the acceleration power and/or using predictive path data supplied in particular by a navigation system for the period of time.

A controller for a hybrid vehicle predicts whether necessary discharging electric power from a power storage device which is required to perform downshift in a transmission exceeds upper-limit discharging electric power of the power storage device when downshift in the transmission is performed in a hybrid vehicle travel mode and controls a compressor rotation speed such that a rate of increase of the compressor rotation speed of a supercharger at the time of performing downshift in the transmission increases as the upper-limit discharging electric power decreases when it is predicted that the necessary discharging electric power exceeds the upper-limit discharging electric power.

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.
