Abstract: A method for controlling a hybrid vehicle including an internal combustion engine and electric motors each coupled to a wheel of a rear axle by a coupling device, and an electronic control unit connected to sensors, to a mechanism selecting a propulsion mode and also to the internal combustion engine and to the electric motors. The method includes: depending on running conditions of the vehicle and depending on the selected propulsion mode, controlling the coupling devices, controlling operation of the internal combustion engine and of the electric motors, and controlling torque of the internal combustion engine and of the electric motors.

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.

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.

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.
