摘要： A method controls a power train of a vehicle immobilized in a parking position, the vehicle being provided with a parking brake device for immobilizing the vehicle and at least one electric motor. The method includes detecting the slope direction and/or slope data when the parking brake device is in an actuated position, detecting that the parking brake device has switched from the actuated position to a released position, and applying a motor torque setpoint to the electric motor in accordance with the detected slope direction and/or slope data.

摘要： 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.

摘要： Disclosed herein is an invention concerning a method for managing charging of a Li-ion battery based on at least one parameter chosen from a group consisting of a state of deterioration of the Li-ion battery and cell unbalance, the method comprising the following steps: determining an end-of-charge voltage value of said Li-ion battery, generating a control signal controlling the charging of said Li-ion battery, and transmitting the control signal to a charger, the control signal being generated in such a way that the Li-ion battery is charged based on the end-of-charge voltage value determined in step a), said end-of-charge voltage value being increased based on the state of deterioration of said Li-ion battery until a limit value is reached, in order to ensure a constant minimal level of required energy in said Li-ion battery is provided at a predetermined reference temperature.

摘要： A body shell structure of a motor vehicle includes a side superstructure of the body shell defining on either side of the vehicle two recess portions for wheel arch housings of the vehicle connected by a floor of the vehicle. The body shell structure includes, in each of the two recess portions for wheel arch housing, a wheel arch housing part and at least one mount for attaching the rear shock absorber, assembled by edges thereof to each of the wheel arch housing parts. The wheel arch housing part defines at least one substantially oblique surface portion around and beyond the edges of the mount. The superstructure also includes a structural plate rigidly connected to an oblique surface portion of the wheel arch housing part and secured to a substantially vertical surface portion of the superstructure.

摘要： A method manages a state of charge of a traction battery of a rechargeable hybrid vehicle including a hybrid power train to provide propulsion. The battery being capable of operating according to a first operating mode over a state of charge range, of which an amplitude is bounded by predefined maximum and minimum state of charge values, in which the battery supplies substantially all power necessary for propulsion, and a second operating mode, in which the state of charge of the battery is kept substantially constantly around an equilibrium state of charge value. The method includes estimating an ageing state of the battery, comparing the estimated ageing state of the battery in relation to a given ageing state threshold, and reducing the amplitude of the state of charge range linked to the first operating mode when the ageing state of the battery rises above the given ageing state threshold.

摘要： A conduit for cooling a heating element includes an inlet mouth for entry of a fresh air flow, a plurality of cooling channels, the fresh air flow dividing between the channels into a plurality of air flows to collect heat produced by the heating element, an outlet mouth for an exit of a heated air flow, the heated air flow resulting from a merger of the plurality of air flows after the heat collection, and air deflectors in the outlet mouth facing the channel outlets situated closest to an exit opening of the outlet mouth relative to the other channel outlets to prevent at least one of the plurality of air flows from exiting the cooling channels. The air deflectors extend over lengths which reduce as distances from the opening of the outlet mouth increase to guide the air flows towards the exit opening of the outlet mouth.
