  • Patent number: 9944290
    Abstract: A method controls regenerative braking of a motor vehicle provided with an electric or hybrid powertrain. The method includes determining that a driver is pressing neither a throttle pedal nor a brake pedal of the vehicle. The method also includes determining a correction coefficient as a function of a torque supplied by a motor of the powertrain, of a speed and an angular velocity at a wheel of the vehicle, of a gradient, of a mass of the vehicle, and of friction. Next, the method includes determining a setpoint for regenerative braking without pressure on the brake pedal as a function of the correction coefficient and of two maps of torque as a function of a rotational speed of the powertrain, for a substantially zero gradient and a vehicle mass substantially equal to a reference mass of the vehicle.

    Abstract: A method for managing the temperature of a battery of an electric or hybrid vehicle includes recording a temperature value at which the cooling or heating of the battery is triggered. The method further includes, for two consecutive values in a predefined sequence of states of charge: a step of comparing a real gradient to a reference gradient of the battery temperature; and a step of modifying, depending on the comparison, the value of the trigger temperature, or the value of the power output by cooling or heating the battery; and also includes applying the modified trigger temperature or output power for the following two consecutive values of the state of charge of the battery in the predefined sequence.

  • Patent number: 9931950
    Abstract: During a method for recovering electrical energy, for example during a deceleration phase of a motor vehicle including at least one electric accumulator battery, a low alternator voltage is applied during a first type of vehicle driving phase, and a high alternator voltage higher than the low alternator voltage is applied for a second type of vehicle driving phase. The transition from the low alternator voltage to the high alternator voltage is carried out by applying a first voltage step of a predefined amplitude, followed by a knee in the voltage curve, the voltage curve then continuing into at least a second voltage ramp phase of which the average slope is strictly lower than the voltage ramp of the first step.

  • Patent number: 9919745
    Abstract: A motor vehicle structure includes two left and right bell-shaped suspension element supports arranged inside a front compartment close to a bulkhead of the vehicle. The suspension element supports are respectively adjacent to side walls of the front compartment. Each of the suspension element supports includes an internal face opposite the side wall. The structure also includes left and right spacers that extend respectively between the left and right suspension element supports and the rigid cross member, in a substantially longitudinal direction. The spacers are respectively anchored to the internal faces of the two suspension element supports. The spacers each have a skirt-shaped edge that can be applied to the suspension element supports, and a folded edge extending between a free end and an opposing attachment end to be joined to the cross member. The spacers include a central portion joining the folded edge and the skirt-shaped edge together.

  • Patent number: 9908534
    Abstract: An operating method for a vehicle includes a driving in manual mode, in which a longitudinal movement and a lateral movement are controlled by a human driver, and a driving in autonomous mode, in which the longitudinal movement and the lateral movement are controlled by an automated system. In the method, an alerting of the human driver is activated in particular in autonomous mode when the automated system receives a first distance that separates the vehicle from an end of the zone in which the autonomous mode is authorized. An automatic stopping of the vehicle before reaching the zone end is activated in autonomous mode when the human driver does not resume control of the vehicle after receiving the first distance from the automated system.
