  • Braking method for hybrid vehicles compensating for an electric braking torque
    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.

  • METHOD FOR BRAKING A HYBRID VEHICLE AND METHOD FOR IMPROVING A HYBRID VEHICLE IMPLEMENTING SAID METHOD
    Publication number: 20100106386
    Abstract: The invention relates to a method for braking a hybrid vehicle (1) including a thermal engine and an electric machine (3) defining a traction chain. According to this method, when the depression of the brake pedal is detected, an additional electric braking torque is added (Cf_recup), and the additional electric braking torque is modulated according to the position of the brake pedal as measured by a pedal stroke sensor (42) and/or to the braking hydraulic pressure as measured by a braking pressure sensor (43).
