  • Publication number: 20120302397
    Abstract: The invention essentially relates to a method for optimising the recharging of a hybrid vehicle battery. When the clutch (10) is in the open position and/or when the gearbox (8) is in neutral, the heat engine (7) is at idling speed (W1) by default when the charge status (SOC) of the high-voltage battery (19) is below a parameterisable threshold or a raised idling speed (W2) when the charge status (SOC) of the high-voltage battery (19) is above the parameterisable threshold in order to increase the power generated by the first electrical machine (11) in order to recharge the battery.

  • Patent number: 8311692
    Abstract: The invention relates to a braking method for a hybrid vehicle (1) comprising a drivetrain (3) controlled by a drivetrain computer (12), and a hydraulic braking system (15) controlled by a braking computer (21). In this method, as soon as the drivetrain computer (12) detects that the electrical braking torque is decreasing, this drivetrain computer (12) informs the hydraulic braking computer (21) of the value of the reduction in electric braking torque. The braking computer (21) then operates the hydraulic braking system (15) in such a way that the hydraulic braking torque applied to the wheels (2) by the brakes (17) compensates for this reduction in electric braking torque.

  • Publication number: 20120253577
    Abstract: A method for disconnecting an electrical machine connected with the wheels of a vehicle's drive axle by means of a dog clutch having intermeshing couplers includes, upon receipt of a command to disengage, two successively activated steps. In the first step, a torque equal to a calibrated threshold of a target torque (d) is applied to the electrical machine so to effect a zero torque between the couplers. During this step, a dog clutch actuator is deactivated so to allow the dog clutch to disengage from the electrical machine as quickly as possible. Next, a torque having a value determined according to a slope whose value ranges from the calibrated threshold of the target torque (d) to zero is applied to the electrical machine.
