  • Patent number: 9611825
    Abstract: A method for monitoring/controlling starting of a heat engine of a hybrid vehicle including at least one electrical engine, including: launching a simulated sequence for starting the heat engine by using a start battery; measuring and recording progress over time of at least one parameter of the start battery, including a given current strength and voltage at terminals of the start battery; and detecting whether or not the progress over time of the at least one parameter reaches a predetermined value defining a state of the start battery, with or without a required capacity, for starting the heat engine during a predetermined time interval.

  • Patent number: 9464561
    Abstract: A cooling system for a hybrid powertrain of a motor vehicle comprising an internal combustion engine and an electric traction assembly, comprising a main circuit that can be traversed by a coolant in order to cool the internal combustion engine to a first temperature level and a secondary circuit that can be traversed by a coolant to cool the electric traction assembly to a second temperature level, lower than the first level, each of the circuits and comprising a radiator capable of cooling the coolant by means of heat exchange with an air flow, at least one hydraulic pump for circulating the coolant in the coolant circuits, and one electronic control unit capable of controlling the hydraulic pumps. The control unit comprises a module for recovering information on the dynamics of the vehicle and a module for controlling the flow from the hydraulic pumps on the basis of that information.

  • Publication number: 20150308398
    Abstract: A method for monitoring/controlling starting of a heat engine of a hybrid vehicle including at least one electrical engine, including: launching a pseudo-sequence for starting the heat engine by using a start battery; measuring and recording progress over time of at least one parameter of the start battery, including a given current strength and voltage at terminals of the start battery; and detecting whether or not the progress over time of the at least one parameter reaches a predetermined value defining a state of the start battery, with or without a required capacity, for starting the heat engine during a given time interval.

  • Publication number: 20090218846
    Abstract: A trapping detection seal for opening leaves, for example motor vehicle opening leaves, of elongate shape with an elastically deformable cross section including a first cut-out region arranged between a first conducting region and a second conduction region so as to enable the two conducting regions to come into contact with one another during deformation of the seal in a first direction. A second cut-out region is arranged between the first conducting region and a third conducting region, the cross section of the seal being deformable in at least a second direction, which is different from the first direction, to enable the first conducting region to come into contact with the third conduction region during deformation of the seal in the second direction.
