Patent number: 10023159Abstract: A method of managing the braking of an aircraft having landing gear with wheels fitted with friction brakes and with auxiliary brakes that enable energy to be dissipated by other than friction. The method comprises the steps of, (1) when braking is requested, testing the braking parameters to determine whether the aircraft is in a braking situation for which the friction brakes are not essential for providing the requested braking, and (2) performing the requested braking by giving priority to actuating the auxiliary brakes so long as the aircraft remains within the braking situation, and actuating the friction brakes only if the aircraft departs from the braking situation.Type: GrantFiled: November 29, 2010Date of Patent: July 17, 2018Assignee: MESSIER-BUGATTI-DOWTYInventors: Anthony Sorin, David Lemay, Michel Basset, Yann Chamaillard

Patent number: 9902391Abstract: A method manages energy of a power unit of a hybrid vehicle. The power unit includes at least one internal combustion engine and an electric drive machine, coupled to wheels of the vehicle by a transmission with discrete ratios. The method includes minimizing, at each operating point of the energy, an energy criterion linked to a sum of consumption of the internal combustion engine and an electrical consumption of the electrical machine multiplied by an equivalence factor weighting a supply of energy from the internal combustion engine and a supply of energy of electrical origin. The minimized criterion is a mixed criterion which is a sum of an energy criterion and a discomfort criterion linked to management of kinematic modes of the transmission.Type: GrantFiled: November 4, 2014Date of Patent: February 27, 2018Assignee: RENAULT s.a.s.Inventors: Thomas Miro-Padonavi, Maxime Debert, Yann Chamaillard, Guillaume Colin

Patent number: 9134730Abstract: The invention relates to a management method for managing a turning movement of an aircraft taxiing on the ground, the aircraft having wheels each fitted with an independent drive device, in which method commands are generated for the independent drive devices so that at least some of those devices contribute to the turning movement. According to the invention, the method comprises the steps of: estimating at each instant during the turning movement: an instantaneous total power developed by all of the independent drive devices in response to the commands; and an instantaneous mean angular acceleration for all of the wheels; and adapting the commands to the independent drive devices such that the total instantaneous power developed by all of the independent drive devices is minimized, while conserving the mean angular acceleration.Type: GrantFiled: May 3, 2011Date of Patent: September 15, 2015Assignee: MESSIER-BUGATTI-DOWTYInventors: David Lemay, David Frank, Michel Basset, Yann Chamaillard
