Abstract: System for controlling the stability of a vehicle, the system comprising means for imparting a longitudinal force to the tire and means for calculating a slip GOpt by determining the values of the coefficient of friction ?i, for each slip Gi corresponding to successive levels “i”, using in parallel “n” calculation algorithms each determining a target value of the slip making it possible thus to obtain as many target values GCn as there are algorithms used, the system selecting the best of the target values GCn as the optimum slip value GOpt by subjecting the “n” target values GCn to comparisons aimed at eliminating the least likely target values, the comparisons being made on the basis of a function f(?) of a descriptor of the physical functioning of the rotation of the tire on the ground making it possible to calculate characteristic values. For example, one interesting characteristic value is the variation in G with respect to time.

Abstract: A system is presented for controlling the stability of a vehicle. The system includes a controller using a slip parameter GOPT corresponding to a predetermined value of the coefficient of friction ? or a controller maintaining the functioning of the tire at an optimal value ?OPT of the drift angle corresponding to the maximum value of the draft thrust Ftarget. The controller performs the following operations (where X is either the slip G or the drift angle ?, and Y is either ? or F). Estimations or measurements are determined for at least one pair of values (Xi, Yi). The corresponding values of the slope ?i are determined for the straight line passing through the origin (Xi, Yi). Coefficients Ap are calculated by direct calculation or by a regression from a sufficient number of pairs with (?i, Xi) so as to model a variation curve ?i=f(Xi, Ap). A target value XTarget is calculated by using a predetermined invariant “Invt”.

Abstract: A telepresence system comprising a workstation which allows a user to specify a venue located at a remote site. The workstation accepts control information from, and conveys sensory information to, the user. The telepresence system also comprises several remotely controlled systems at remote locations, which carry sensors collecting sensory information from their environment. Each remotely controlled system also requires human assistance to operate according to control information sent by the user. The telepresence system also comprises a means for allocating one of the remotely controlled systems to the specified venue. The telepresence system also comprises a means for allocating a human assistant to assist the allocated remote system.
