Abstract: A method for controlling command of lifting a load suspended from a boom, carried by a mast of a crane, includes determining: depending on the mass of the suspended load, a specified load factor quantifying an acceptable exceedance with respect to a predetermined maximum allowable load for said crane; a maximum permitted lifting acceleration, depending on the mass of the suspended load, on the specified load factor and on the distribution position of the load suspended on the boom with respect to the mast; from lifting speed setpoints, optimized lifting speed setpoints intended to be executed by a motor device for displacing the suspended load according to a lifting movement so that the acceleration related to the lifting movement remains, in absolute value, less than or equal to the maximum permitted acceleration.

Abstract: A method for controlling displacement of a load suspended to a point of attachment of a lifting machine includes an acquisition step during which a piloting setpoint is acquired and which is representative of the displacement speed that the operator wishes to confer on the suspended load, a processing step during which a setpoint called execution setpoint, which is applied to a drive motor in order to displace the suspended load, is elaborated from the piloting setpoint, the processing step including a C3 smoothing substep by third-order filtering during which a third-order filter is applied to the piloting setpoint in order to generate a filtered piloting setpoint of smoothness class C3, and the execution setpoint is defined from the filtered piloting setpoint.

Abstract: The invention relates to a four wheel drive hybrid vehicle provided with at least one power train on each wheel set, a first power train (1) including at least one heat engine, a second power train (2) including at least one electric machine, the vehicle also being provided with a friction braking system on each drive wheel and sensor (7).

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.

Abstract: A method for estimating the derivative of a motor vehicle wheel slippage including: a) inputting data concerning speed of the wheels, engine torques applied on the wheels, braking pressures, engaged gearbox ratio; b) estimating acceleration of each wheel while performing a discrete derivation and a filtering of the speed of each wheel; c) estimating the torque applied to each wheel taking into account the braking pressure, engaged gearbox ratio, and clutch status; d) estimating inertia of the wheels for each of the vehicle front and rear axles; e) performing a geometric transformation of the estimate of the acceleration of each wheel estimated in b); f) estimating the derivation of the slippage of each wheel, based on the values estimated in c), d) and e).
