    Abstract: A method compensates for wheel torque interruption for a change in braking ratio in a vehicle with an electric traction unit linked to wheels by a gearbox that transmits, to the wheels, the braking torque of the electric traction unit in the deceleration phase over at least two transmission ratios, and a mechanical braking system acting on the wheels independently of the electric traction unit. The method includes defining a setpoint for mechanical braking torque at the wheels, depending on the control type of the electric traction unit, and the date of the downshift ratio change request to the gearbox. The mechanical braking torque setpoint is equal to the difference between an anticipated torque request to the electric traction unit and the estimation of the torque at the wheel, before the date of the end of the shift at the gearbox, if the electric traction unit is torque-controlled.

    Abstract: A method for estimating residual capacities of a plurality of batteries connected to an electrical power distribution network includes storing in the batteries energy coming from the network, releasing to return the energy to the network, gathering information relating to physical quantities to determine a state of ageing of each battery, during the storing, charging a selected battery until a predefined maximum charge level is reached, during the releasing, discharging the selected battery, if the selected battery has reached the maximum charge level during the storing, until a predefined minimum charge level is reached, or making the selected battery inactive if the selected battery has not yet reached the predefined maximum charge level, then measuring a level of energy yielded by the selected battery, and calculating a residual capacity of the selected battery based on the measurement of the level of energy yielded by the battery.
